Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real-world are "augmented" by computer-generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory, and olfactory. The overlaid sensory information can be constructive (i.e. additive to the natural environment) or destructive (i.e. masking of the natural environment) and is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, whereas virtual reality completely replaces the user's real-world environment with a simulated one. Augmented reality is related to two largely synonymous terms: mixed reality and computer-mediated reality.
The primary value of augmented reality is that it brings components of the digital world into a person's perception of the real world, and does so not as a simple display of data, but through the integration of immersive sensations that are perceived as natural parts of an environment. The first functional AR systems that provided immersive mixed reality experiences for users were invented in the early 1990s, starting with the Virtual Fixtures system developed at the U.S. Air Force's Armstrong Laboratory in 1992. The first commercial augmented reality experiences were used largely in the entertainment and gaming businesses, but now other industries are also getting interested about AR's possibilities for example in knowledge sharing, educating, managing the information flood and organizing distant meetings. Augmented reality is also transforming the world of education, where content may be accessed by scanning or viewing an image with a mobile device or by bringing immersive, markerless AR experiences to the classroom. Another example is an AR helmet for construction workers which display information about the construction sites.
Augmented reality is used to enhance natural environments or situations and offer perceptually enriched experiences. With the help of advanced AR technologies (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally manipulable. Information about the environment and its objects is overlaid on the real world. This information can be virtual or real, e.g. seeing other real sensed or measured information such as electromagnetic radio waves overlaid in exact alignment with where they actually are in space. Augmented reality also has a lot of potential in the gathering and sharing of tacit knowledge. Augmentation techniques are typically performed in real time and in semantic context with environmental elements. Immersive perceptual information is sometimes combined with supplemental information like scores over a live video feed of a sporting event. This combines the benefits of both augmented reality technology and heads up display technology (HUD).

Hardware components for augmented reality are: processor, display, sensors and input devices. Modern mobile computing devices like smartphones and tablet computers contain these elements which often include a camera and MEMS sensors such as accelerometer, GPS, and solid state compass, making them suitable AR platforms.
There are 2 technologies: diffractive waveguides and reflective waveguides. Augmented reality systems guru Karl Guttag compared the optics of diffractive waveguides against the competing technology, reflective waveguides.
A head-mounted display (HMD) is a display device worn on the forehead, such as a harness or helmet. HMDs place images of both the physical world and virtual objects over the user's field of view. Modern HMDs often employ sensors for six degrees of freedom monitoring that allow the system to align virtual information to the physical world and adjust accordingly with the user's head movements. HMDs can provide VR users with mobile and collaborative experiences. Specific providers, such as uSens and Gestigon, include gesture controls for full virtual immersion.
In January 2015, Meta launched a project led by Horizons Ventures, Tim Draper, Alexis Ohanian, BOE Optoelectronics and Garry Tan. On February 17, 2016, Meta announced their second-generation product at TED, Meta 2. The Meta 2 head-mounted display headset uses a sensory array for hand interactions and positional tracking, visual field view of 90 degrees (diagonal), and resolution display of 2560 x 1440 (20 pixels per degree), which is considered the largest field of view (FOV) currently available.
AR displays can be rendered on devices resembling eyeglasses. Versions include eyewear that employs cameras to intercept the real world view and re-display its augmented view through the eyepieces and devices in which the AR imagery is projected through or reflected off the surfaces of the eyewear's lenspieces.
A head-up display (HUD) is a transparent display that presents data without requiring users to look away from their usual viewpoints. A precursor technology to augmented reality, heads-up displays were first developed for pilots in the 1950s, projecting simple flight data into their line of sight, thereby enabling them to keep their "heads up" and not look down at the instruments. Near-eye augmented reality devices can be used as portable head-up displays as they can show data, information, and images while the user views the real world. Many definitions of augmented reality only define it as overlaying the information. This is basically what a head-up display does; however, practically speaking, augmented reality is expected to include registration and tracking between the superimposed perceptions, sensations, information, data, and images and some portion of the real world.
A number of smartglasses have been launched for augmented reality. Due to encumbered control, smartglasses are primarily designed for micro-interaction like reading a text message but still far from more well-rounded applications of augmented reality.
Contact lenses that display AR imaging are in development. These bionic contact lenses might contain the elements for display embedded into the lens including integrated circuitry, LEDs and an antenna for wireless communication. The first contact lens display was reported in 1999, then 11 years later in 2010-2011. Another version of contact lenses, in development for the U.S. military, is designed to function with AR spectacles, allowing soldiers to focus on close-to-the-eye AR images on the spectacles and distant real world objects at the same time.
Many scientists have been working on contact lenses capable of many different technological feats. The company Samsung has been working on a contact lens as well. This lens, when finished, is meant to have a built-in camera on the lens itself. The design is intended to have you blink to control its interface for recording purposes. It is also intended to be linked with your smartphone to review footage, and control it separately. When successful, the lens would feature a camera, or sensor inside of it. It is said that it could be anything from a light sensor, to a temperature sensor.
In Augmented Reality, the distinction is made between two distinct modes of tracking, known as marker and markerless. Marker are visual cues which trigger the display of the virtual information. A piece of paper with some distinct geometries can be used. The camera recognizes the geometries by identifying specific points in the drawing. Markerless tracking, also called instant tracking, does not use markers. Instead the user positions the object in the camera view preferably in a horizontal plane. It uses sensors in mobile devices to accurately detect the real-world environment, such as the locations of walls and points of intersection.
Virtual retinal display
A virtual retinal display (VRD) is a personal display device under development at the University of Washington's Human Interface Technology Laboratory under Dr. Thomas A. Furness III. With this technology, a display is scanned directly onto the retina of a viewer's eye. This results in bright images with high resolution and high contrast. The viewer sees what appears to be a conventional display floating in space.
Several of tests were done in order to analyze the safety of the VRD. In one test, patients with partial loss of vision were selected to view images using the technology having either macular degeneration (a disease that degenerates the retina) or keratoconus. In the macular degeneration group, 5 out of 8 subjects preferred the VRD images to the CRT or paper images and thought they were better and brighter and were able to see equal or better resolution levels. The Kerocunus patients could all resolve smaller lines in several line tests using the VDR as opposed to their own correction. They also found the VDR images to be easier to view and sharper. As a result of these several tests, virtual retinal display is considered safe technology.
Virtual retinal display creates images that can be seen in ambient daylight and ambient roomlight. The VRD is considered a preferred candidate to use in a surgical display due to its combination of high resolution and high contrast and brightness. Additional tests show high potential for VRD to be used as a display technology for patients that have low vision.
The EyeTap (also known as Generation-2 Glass) captures rays of light that would otherwise pass through the center of the lens of the eye of the wearer, and substitutes synthetic computer-controlled light for each ray of real light.
The Generation-4 Glass (Laser EyeTap) is similar to the VRD (i.e. it uses a computer-controlled laser light source) except that it also has infinite depth of focus and causes the eye itself to, in effect, function as both a camera and a display by way of exact alignment with the eye and resynthesis (in laser light) of rays of light entering the eye.
A Handheld display employs a small display that fits in a user's hand. All handheld AR solutions to date opt for video see-through. Initially handheld AR employed fiducial markers, and later GPS units and MEMS sensors such as digital compasses and six degrees of freedom accelerometer–gyroscope. Today SLAM markerless trackers such as PTAM are starting to come into use. Handheld display AR promises to be the first commercial success for AR technologies. The two main advantages of handheld AR are the portable nature of handheld devices and the ubiquitous nature of camera phones. The disadvantages are the physical constraints of the user having to hold the handheld device out in front of them at all times, as well as the distorting effect of classically wide-angled mobile phone cameras when compared to the real world as viewed through the eye.
Spatial augmented reality (SAR) augments real-world objects and scenes without the use of special displays such as monitors, head-mounted displays or hand-held devices. SAR makes use of digital projectors to display graphical information onto physical objects. The key difference in SAR is that the display is separated from the users of the system. Because the displays are not associated with each user, SAR scales naturally up to groups of users, thus allowing for collocated collaboration between users.
Examples include shader lamps, mobile projectors, virtual tables, and smart projectors. Shader lamps mimic and augment reality by projecting imagery onto neutral objects, providing the opportunity to enhance the object's appearance with materials of a simple unit - a projector, camera, and sensor.
Other applications include table and wall projections. One innovation, the Extended Virtual Table, separates the virtual from the real by including beam-splitter mirrors attached to the ceiling at an adjustable angle. Virtual showcases, which employ beam-splitter mirrors together with multiple graphics displays, provide an interactive means of simultaneously engaging with the virtual and the real. Many more implementations and configurations make spatial augmented reality display an increasingly attractive interactive alternative.
A SAR system can display on any number of surfaces of an indoor setting at once. SAR supports both a graphical visualization and passive haptic sensation for the end users. Users are able to touch physical objects in a process that provides passive haptic sensation.
Modern mobile augmented-reality systems use one or more of the following motion tracking technologies: digital cameras and/or other optical sensors, accelerometers, GPS, gyroscopes, solid state compasses, RFID. These technologies offer varying levels of accuracy and precision. The most important is the position and orientation of the user's head. Tracking the user's hand(s) or a handheld input device can provide a 6DOF interaction technique.
Mobile augmented reality applications are gaining popularity due to the wide adoption of mobile and especially wearable devices. However, they often rely on computationally intensive computer vision algorithms with extreme latency requirements. To compensate for the lack of computing power, offloading data processing to a distant machine is often desired. Computation offloading introduces new constraints in applications, especially in terms of latency and bandwidth. Although there are a plethora of real-time multimedia transport protocols, there is a need for support from network infrastructure as well.
Techniques include speech recognition systems that translate a user's spoken words into computer instructions, and gesture recognition systems that interpret a user's body movements by visual detection or from sensors embedded in a peripheral device such as a wand, stylus, pointer, glove or other body wear. Products which are trying to serve as a controller of AR headsets include Wave by Seebright Inc. and Nimble by Intugine Technologies.
The computer analyzes the sensed visual and other data to synthesize and position augmentations. Computers are responsible for the graphics that go with augmented reality. Augmented reality uses a computer-generated image and it has an striking effect on the way the real world is shown. With the improvement of technology and computers, augmented reality is going to have a drastic change on our perspective of the real world. According to Time Magazine, in about 15–20 years it is predicted that Augmented reality and virtual reality are going to become the primary use for computer interactions. Computers are improving at a very fast rate, which means that we are figuring out new ways to improve other technology. The more that computers progress, augmented reality will become more flexible and more common in our society. Computers are the core of augmented reality.
 The Computer receives data from the sensors which determine the relative position of objects surface. This translates to an input to the computer which then outputs to the users by adding something that would otherwise not be there. The computer comprises memory and a processor. The computer takes the scanned environment then generates images or a video and puts it on the receiver for the observer to see. The fixed marks on an objects surface are stored in the memory of a computer. The computer also withdrawals from its memory to present images realistically to the onlooker. The best example of this is of the Pepsi Max AR Bus Shelter.
Software and algorithms
A key measure of AR systems is how realistically they integrate augmentations with the real world. The software must derive real world coordinates, independent from the camera, from camera images. That process is called image registration, and uses different methods of computer vision, mostly related to video tracking. Many computer vision methods of augmented reality are inherited from visual odometry.
Usually those methods consist of two parts. The first stage is to detect interest points, fiducial markers or optical flow in the camera images. This step can use feature detection methods like corner detection, blob detection, edge detection or thresholding, and other image processing methods. The second stage restores a real world coordinate system from the data obtained in the first stage. Some methods assume objects with known geometry (or fiducial markers) are present in the scene. In some of those cases the scene 3D structure should be precalculated beforehand. If part of the scene is unknown simultaneous localization and mapping (SLAM) can map relative positions. If no information about scene geometry is available, structure from motion methods like bundle adjustment are used. Mathematical methods used in the second stage include projective (epipolar) geometry, geometric algebra, rotation representation with exponential map, kalman and particle filters, nonlinear optimization, robust statistics.
Augmented Reality Markup Language (ARML) is a data standard developed within the Open Geospatial Consortium (OGC), which consists of XML grammar to describe the location and appearance of virtual objects in the scene, as well as ECMAScript bindings to allow dynamic access to properties of virtual objects.
To enable rapid development of augmented reality applications, some software development kits (SDKs) have emerged. A few SDKs such as CloudRidAR leverage cloud computing for performance improvement. AR SDKs are offered by Vuforia, ARToolKit, Catchoom CraftAR Mobinett AR, Wikitude, Blippar Layar, Meta. and ARLab.
The implementation of Augmented Reality in consumer products requires considering the design of the applications and the related constraints of the technology platform. Since AR system rely heavily on the immersion of the user and the interaction between the user and the system, design can facilitate the adoption of virtuality. For most Augmented Reality systems, a similar design guideline can be followed. The following lists some considerations for designing Augmented Reality applications:
Context Design focuses on the end-user's physical surrounding, spatial space, and accessibility that may play a role when using the AR system. Designers should be aware of the possible physical scenarios the end-user may be in such as:
- Public, in which the users uses their whole body to interact with the software
- Personal, in which the user uses a smartphone in a public space
- Intimate, in which the user is sitting with a desktop and is not really in movement
- Private, in which the user has on a wearable.
By evaluating each physical scenario, potential safety hazard can be avoided and changes can be made to greater improve the end-user's immersion. UX designers will have to define user journeys for the relevant physical scenarios and define how the interface will react to each.
Especially in AR systems, it is vital to also consider the spatial space and the surrounding elements that change the effectiveness of the AR technology. Environmental elements such as lighting, and sound can prevent the sensor of AR devices from detecting necessary data and ruin the immersion of the end-user.
Another aspect of context design involves the design of the system's functionality and its ability to accommodate for user preferences. While accessibility tools are common in basic application design, some consideration should be made when designing time-limited prompts (to prevent unintentional operations), audio cues and overall engagement time. It is important to note that in some situations, the application's functionality may hinder the user's ability. For example, applications that is used for driving should reduce the amount of user interaction and user audio cues instead.
Interaction design in augmented reality technology centers on the user's engagement with the end product to improve the overall user experience and enjoyment. The purpose of Interaction Design is to avoid alienating or confusing the user by organising the information presented. Since user interaction relies on the user's input, designers must make system controls easier to understand and accessible. A common technique to improve usability for augmented reality applications is by discovering the frequently accessed areas in the device's touch display and design the application to match those areas of control. It is also important to structure the user journey maps and the flow of information presented which reduce the system's overall cognitive load and greatly improves the learning curve of the application.
In interaction design, it is important for developers to utilize augmented reality technology that complement the system's function or purpose. For instance, the utilization of exciting AR filters and the design of the unique sharing platform in Snapchat enables users to better the user's social interactions. In other applications that require users to understand the focus and intent, designers can employ a reticle or raycast from the device. Moreover, augmented reality developers may find it appropriate to have digital elements scale or react to the direction of the camera and the context of objects that can are detected.
In general, visual design is the appearance of the developing application that engages the user. To improve the graphic interface elements and user interaction, developers may use visual cues to inform user what elements of UI are designed to interact with and how to interact with them. Since navigating in AR application may appear difficult and seem frustrating, visual cues design can make interactions seem more natural.
In some augmented reality applications that uses a 2D device as an interactive surface, the 2D control environment does not translate well in 3D space making users hesitant to explore their surroundings. To solve this issue, designers should apply visual cues to assist and encourage users to explore their surroundings.
It is important to note the two main objects in AR when developing VR applications: 3D volumetric objects that are manipulatable and realistically interact with light and shadow; and animated media imagery such as images and videos which are mostly traditional 2D media rendered in a new context for augmented reality. When virtual objects are projected onto a real environment, it is challenging for augmented reality application designers to ensure a perfectly seamless integration relative to the real-world environment, especially with 2D objects. As such, designers can add weight to objects, use depths maps, and choose different material properties that highlight the object's presence in the real world. Another visual design that can be applied is using different lighting techniques or casting shadows to improve overall depth judgment. For instance, a common lighting technique is simply placing a light source overhead at the 12 o’clock position, to create shadows upon virtual objects.

Augmented reality has been explored for many applications, from gaming and entertainment to medicine, education and business. Example application areas described below include Archaeology, Architecture, Commerce and Education. Some of the earliest cited examples include Augmented Reality used to support surgery by providing virtual overlays to guide medical practitioners to AR content for astronomy and welding.
The first description of AR as it is known today was in Virtual Light, the 1994 novel by William Gibson. In 2011, AR was blended with poetry by ni ka from Sekai Camera in Tokyo, Japan. The prose of these AR poems come from Paul Celan, "Die Niemandsrose", expressing the aftermath of the 2011 Tōhoku earthquake and tsunami.
AR has been used to aid archaeological research. By augmenting archaeological features onto the modern landscape, AR allows archaeologists to formulate possible site configurations from extant structures. Computer generated models of ruins, buildings, landscapes or even ancient people have been recycled into early archaeological AR applications. For example, implementing a system like, "VITA (Visual Interaction Tool for Archaeology)" will allow users to imagine and investigate instant excavation results without leaving their home. Each user can collaborate by mutually "navigating, searching, and viewing data." Hrvoje Benko, a researcher for the computer science department at Columbia University, points out that these particular systems and others like it can provide "3D panoramic images and 3D models of the site itself at different excavation stages" all the while organizing much of the data in a collaborative way that is easy to use. Collaborative AR systems supply multimodal interactions that combine the real world with virtual images of both environments. AR has been recently adopted also in the underwater archaeology field to efficiently support and facilitate the manipulation of archaeological artefacts.
AR can aid in visualizing building projects. Computer-generated images of a structure can be superimposed into a real-life local view of a property before the physical building is constructed there; this was demonstrated publicly by Trimble Navigation in 2004. AR can also be employed within an architect's workspace, rendering animated 3D visualizations of their 2D drawings. Architecture sight-seeing can be enhanced with AR applications, allowing users viewing a building's exterior to virtually see through its walls, viewing its interior objects and layout.
With the continual improvements to GPS accuracy, businesses are able to use augmented reality to visualize georeferenced models of construction sites, underground structures, cables and pipes using mobile devices. Augmented reality is applied to present new projects, to solve on-site construction challenges, and to enhance promotional materials. Examples include the Daqri Smart Helmet, an Android-powered hard hat used to create augmented reality for the industrial worker, including visual instructions, real-time alerts, and 3D mapping.
Following the Christchurch earthquake, the University of Canterbury released CityViewAR, which enabled city planners and engineers to visualize buildings that had been destroyed. Not only did this provide planners with tools to reference the previous cityscape, but it also served as a reminder to the magnitude of the devastation caused, as entire buildings had been demolished.
AR applied in the visual arts allows objects or places to trigger artistic multidimensional experiences and interpretations of reality.
Augmented Reality can aid in the progression of visual art in museums by allowing museum visitors to view artwork in galleries in a multidimensional way through their phone screens. The Museum of Modern Art in New York has created an exhibit in their art museum showcasing Augmented Reality features that viewers can see using an app on their smartphone. The museum has developed their personal app, called MoMAR Gallery, that museum guests can download and use in the Augmented Reality specialized gallery in order to view the museum's paintings in a different way. This allows individuals to see hidden aspects and information about the paintings, and to be able to have an interactive technological experience with artwork as well.
AR is used to integrate print and video marketing. Printed marketing material can be designed with certain "trigger" images that, when scanned by an AR-enabled device using image recognition, activate a video version of the promotional material. A major difference between augmented reality and straightforward image recognition is that one can overlay multiple media at the same time in the view screen, such as social media share buttons, the in-page video even audio and 3D objects. Traditional print-only publications are using augmented reality to connect many different types of media.
AR can enhance product previews such as allowing a customer to view what's inside a product's packaging without opening it. AR can also be used as an aid in selecting products from a catalog or through a kiosk. Scanned images of products can activate views of additional content such as customization options and additional images of the product in its use.
By 2010, virtual dressing rooms had been developed for e-commerce.
In 2012, a mint used AR techniques to market a commemorative coin for Aruba. The coin itself was used as an AR trigger, and when held in front of an AR-enabled device it revealed additional objects and layers of information that were not visible without the device.
In 2015, the Bulgarian startup iGreet developed its own AR technology and used it to make the first premade "live" greeting card. A traditional paper card was augmented with digital content which was revealed by using the iGreet app.
In 2017, Ikea announced Ikea Place app. The app contains a catalogue of over 2,000 products—nearly the company's full collection of umlauted sofas, armchairs, coffee tables, and storage units which one can place anywhere in a room with their phone.
In 2018, Apple announced USDZ AR file support for iPhones and iPads with iOS12. Apple has created an AR QuickLook Gallery that allows masses experience Augmented reality on their own Apple device.
In 2018, Shopify, the Canadian commerce company, announced ARkit2 integrations and their merchants are able to use the tools to upload 3D models of their products, which users will be able to tap on the goods inside Safari to view in their real-world environments.
In 2018, Twinkl released free AR classroom application, pupils can see how York looked over 1,900 years ago. Twinkl launched the first ever multi-player AR game, Little Red and has over 100 free AR educational models.
In educational settings, AR has been used to complement a standard curriculum. Text, graphics, video, and audio may be superimposed into a student's real-time environment. Textbooks, flashcards and other educational reading material may contain embedded "markers" or triggers that, when scanned by an AR device, produced supplementary information to the student rendered in a multimedia format.
As AR evolves, students can participate interactively and interact with knowledge more authentically. Instead of remaining passive recipients, students can become active learners, able to interact with their learning environment. Computer-generated simulations of historical events allow students to explore and learning details of each significant area of the event site.
In higher education, Construct3D, a Studierstube system, allows students to learn mechanical engineering concepts, math or geometry. Chemistry AR apps allow students to visualize and interact with the spatial structure of a molecule using a marker object held in the hand. Others have used HP Reveal, a free app, to create AR notecards for studying organic chemistry mechanisms or to create virtual demonstrations of how to use laboratory instrumentation. Anatomy students can visualize different systems of the human body in three dimensions.
Primary school children learn easily from interactive experiences. Astronomical constellations and the movements of objects in the solar system were oriented in 3D and overlaid in the direction the device was held, and expanded with supplemental video information. Paper-based science book illustrations could seem to come alive as video without requiring the child to navigate to web-based materials.
In 2013, a project was launched on Kickstarter to teach about electronics with an educational toy that allowed children to scan their circuit with an iPad and see the electric current flowing around. While some educational apps were available for AR by 2016, it was not broadly used. Apps that leverage augmented reality to aid learning included SkyView for studying astronomy, AR Circuits for building simple electric circuits, and SketchAr for drawing.
AR would also be a way for parents and teachers to achieve their goals for modern education, which might include providing a more individualized and flexible learning, making closer connections between what is taught at school and the real world, and helping students to become more engaged in their own learning.
A recent research compared the functionalities of augmented reality tools with potential for education 
Emergency management/search and rescue
Augmented reality systems are used in public safety situations, from super storms to suspects at large.
As early as 2009, two articles from Emergency Management magazine discussed the power of this technology for emergency management. The first was "Augmented Reality--Emerging Technology for Emergency Management" by Gerald Baron. Per Adam Crowe: "Technologies like augmented reality (ex: Google Glass) and the growing expectation of the public will continue to force professional emergency managers to radically shift when, where, and how technology is deployed before, during, and after disasters." Moreover, a 2018 article in the Journal of Agromedicine describes lessons learned from the development of an augmented reality prototype app developed to assist emergency responders in rural and agricultural environments. The article also describes this application's utility and current use as a training tool with rural firefighters, part of a National Farm Medicine Center research project on agricultural safety throughout Wisconsin and Minnesota.
Another early example was a search aircraft looking for a lost hiker in rugged mountain terrain. Augmented reality systems provided aerial camera operators with a geographic awareness of forest road names and locations blended with the camera video. The camera operator was better able to search for the hiker knowing the geographic context of the camera image. Once located, the operator could more efficiently direct rescuers to the hiker's location because the geographic position and reference landmarks were clearly labeled.
AR can be used to facilitate social interaction. An augmented reality social network framework called Talk2Me enables people to disseminate information and view others’ advertised information in an augmented reality way. The timely and dynamic information sharing and viewing functionalities of Talk2Me help initiate conversations and make friends for users with people in physical proximity.
Augmented reality also Gives users the ability to practice different forms of social interactions with other people in a safe, risk-free environment. Hannes Kauffman, Associate Professor for Virtual Reality at TU Vienna, says “In collaborative Augmented Reality multiple users may access a shared space populated by virtual objects, while remaining grounded in the real world. This technique is particularly powerful for educational purposes when users are collocated and can use natural means of communication (speech, gestures etc.), but can also be mixed successfully with immersive VR or remote collaboration.” (Hannes)Hannes cites a specific use for this technology, education.
The gaming industry embraced AR technology. A number of games were developed for prepared indoor environments, such as AR air hockey, Titans of Space, collaborative combat against virtual enemies, and AR-enhanced pool table games.
Augmented reality allowed video game players to experience digital game play in a real-world environment. Companies and platforms like Niantic and Proxy42 emerged as major augmented reality gaming creators. Niantic is notable for releasing the record-breaking game Pokémon Go. Disney has partnered with Lenovo to create the augmented reality game Star Wars: Jedi Challenges that works with a Lenovo Mirage AR headset, a tracking sensor and a Lightsaber controller, scheduled to launch in December 2017.
AR allows industrial designers to experience a product's design and operation before completion. Volkswagen has used AR for comparing calculated and actual crash test imagery. AR has been used to visualize and modify car body structure and engine layout. It has also been used to compare digital mock-ups with physical mock-ups for finding discrepancies between them.
AR provides surgeons with patient monitoring data in the style of a fighter pilot's heads-up display, and allows patient imaging records, including functional videos, to be accessed and overlaid. Examples include a virtual X-ray view based on prior tomography or on real-time images from ultrasound and confocal microscopy probes, visualizing the position of a tumor in the video of an endoscope, or radiation exposure risks from X-ray imaging devices. AR can enhance viewing a fetus inside a mother's womb. Siemens, Karl Storz and IRCAD have developed a system for laparoscopic liver surgery that uses AR to view sub-surface tumors and vessels. AR has been used for cockroach phobia treatment. Patients wearing augmented reality glasses can be reminded to take medications. Virtual reality has been seen promising in the medical field since the 90's. Augmented reality can be very helpful in the medical field. It could be used to provide crucial information to a doctor or surgeon with having them take their eyes off the patient. On the 30th of April, 2015 Microsoft announced the Microsoft HoloLens, their first shot at augmented reality. The HoloLens has advanced through the years and it has gotten so advanced that it has been used to project holograms for near infrared fluorescence based image guided surgery. As augment reality advances, the more it is implemented into medical use. Augmented reality and other computer based-utility is being used today to help train medical professionals. With the creation of Google Glass and Microsoft HoloLens, has helped pushed Augmented Reality into medical education.
Spatial immersion and interaction
Augmented reality applications, running on handheld devices utilized as virtual reality headsets, can also digitalize human presence in space and provide a computer generated model of them, in a virtual space where they can interact and perform various actions. Such capabilities are demonstrated by "Project Anywhere", developed by a postgraduate student at ETH Zurich, which was dubbed as an "out-of-body experience".
Building on decades of perceptual-motor research in experimental psychology, researchers at the Aviation Research Laboratory of the University of Illinois at Urbana-Champaign used augmented reality in the form of a flight path in the sky to teach flight students how to land a flight simulator. An adaptive augmented schedule in which students were shown the augmentation only when they departed from the flight path proved to be a more effective training intervention than a constant schedule. Flight students taught to land in the simulator with the adaptive augmentation learned to land a light aircraft more quickly than students with the same amount of landing training in the simulator but with constant augmentation or without any augmentation.
An interesting early application of AR occurred when Rockwell International created video map overlays of satellite and orbital debris tracks to aid in space observations at Air Force Maui Optical System. In their 1993 paper "Debris Correlation Using the Rockwell WorldView System" the authors describe the use of map overlays applied to video from space surveillance telescopes. The map overlays indicated the trajectories of various objects in geographic coordinates. This allowed telescope operators to identify satellites, and also to identify and catalog potentially dangerous space debris.
Starting in 2003 the US Army integrated the SmartCam3D augmented reality system into the Shadow Unmanned Aerial System to aid sensor operators using telescopic cameras to locate people or points of interest. The system combined both fixed geographic information including street names, points of interest, airports, and railroads with live video from the camera system. The system offered a "picture in picture" mode that allows the system to show a synthetic view of the area surrounding the camera's field of view. This helps solve a problem in which the field of view is so narrow that it excludes important context, as if "looking through a soda straw". The system displays real-time friend/foe/neutral location markers blended with live video, providing the operator with improved situational awareness.
As of 2010, Korean researchers are looking to implement mine-detecting robots into the military. The proposed design for such a robot includes a mobile platform that is like a track which would be able to cover uneven distances including stairs. The robot's mine detection sensor would include a combination of metal detectors and ground penetration radars to locate mines or IEDs. This unique design would be immeasurably helpful in saving lives of Korean soldiers.
Researchers at USAF Research Lab (Calhoun, Draper et al.) found an approximately two-fold increase in the speed at which UAV sensor operators found points of interest using this technology. This ability to maintain geographic awareness quantitatively enhances mission efficiency. The system is in use on the US Army RQ-7 Shadow and the MQ-1C Gray Eagle Unmanned Aerial Systems.
In combat, AR can serve as a networked communication system that renders useful battlefield data onto a soldier's goggles in real time. From the soldier's viewpoint, people and various objects can be marked with special indicators to warn of potential dangers. Virtual maps and 360° view camera imaging can also be rendered to aid a soldier's navigation and battlefield perspective, and this can be transmitted to military leaders at a remote command center.
The NASA X-38 was flown using a Hybrid Synthetic Vision system that overlaid map data on video to provide enhanced navigation for the spacecraft during flight tests from 1998 to 2002. It used the LandForm software and was useful for times of limited visibility, including an instance when the video camera window frosted over leaving astronauts to rely on the map overlays. The LandForm software was also test flown at the Army Yuma Proving Ground in 1999. In the photo at right one can see the map markers indicating runways, air traffic control tower, taxiways, and hangars overlaid on the video.
AR can augment the effectiveness of navigation devices. Information can be displayed on an automobile's windshield indicating destination directions and meter, weather, terrain, road conditions and traffic information as well as alerts to potential hazards in their path. Since 2012, a Swiss-based company WayRay has been developing holographic AR navigation systems that use holographic optical elements for projecting all route-related information including directions, important notifications, and points of interest right into the drivers’ line of sight and far ahead of the vehicle. Aboard maritime vessels, AR can allow bridge watch-standers to continuously monitor important information such as a ship's heading and speed while moving throughout the bridge or performing other tasks.
Augmented reality may have a good impact on work collaboration as people may be inclined to interact more actively with their learning environment. It may also encourage tacit knowledge renewal which makes firms more competitive. AR was used to facilitate collaboration among distributed team members via conferences with local and virtual participants. AR tasks included brainstorming and discussion meetings utilizing common visualization via touch screen tables, interactive digital whiteboards, shared design spaces and distributed control rooms.
In industrial environments, augmented reality is proving to have a substantial impact with more and more use cases emerging across all aspect of the product lifecycle, starting from product design and new product introduction (NPI) to manufacturing to service and maintenance, to material handling and distribution. For example, labels were displayed on parts of a system to clarify operating instructions for a mechanic performing maintenance on a system. Assembly lines benefited from the usage of AR. In addition to Boeing, BMW and Volkswagen were known for incorporating this technology into assembly lines for monitoring process improvements. Big machines are difficult to maintain because of their multiple layers or structures. AR permits people to look through the machine as if with an x-ray, pointing them to the problem right away.
As AR technology has evolved and second and third generation AR devices come to market, the impact of AR in enterprise continues to flourish. In a Harvard Business Review, Magid Abraham and Marco Annunziata discuss how AR devices are now being used to "boost workers’ productivity on an array of tasks the first time they're used, even without prior training." They go on to contend that "these technologies increase productivity by making workers more skilled and efficient, and thus have the potential to yield both more economic growth and better jobs."
Broadcast and live events
Weather visualizations were the first application of augmented reality to television. It has now become common in weathercasting to display full motion video of images captured in real-time from multiple cameras and other imaging devices. Coupled with 3D graphics symbols and mapped to a common virtual geospace model, these animated visualizations constitute the first true application of AR to TV.
AR has become common in sports telecasting. Sports and entertainment venues are provided with see-through and overlay augmentation through tracked camera feeds for enhanced viewing by the audience. Examples include the yellow "first down" line seen in television broadcasts of American football games showing the line the offensive team must cross to receive a first down. AR is also used in association with football and other sporting events to show commercial advertisements overlaid onto the view of the playing area. Sections of rugby fields and cricket pitches also display sponsored images. Swimming telecasts often add a line across the lanes to indicate the position of the current record holder as a race proceeds to allow viewers to compare the current race to the best performance. Other examples include hockey puck tracking and annotations of racing car performance and snooker ball trajectories.
Augmented reality for Next Generation TV allows viewers to interact with the programs they were watching. They can place objects into an existing program and interact with them, such as moving them around. Objects include avatars of real persons in real time who are also watching the same program.
AR has been used to enhance concert and theater performances. For example, artists allow listeners to augment their listening experience by adding their performance to that of other bands/groups of users.
Tourism and sightseeing
Travelers may use AR to access real-time informational displays regarding a location, its features, and comments or content provided by previous visitors. Advanced AR applications include simulations of historical events, places, and objects rendered into the landscape.
Companies can use AR to attract tourists to particular areas that they may not be familiar with by name. Tourists will be able to experience beautiful landscapes in first person with the use of AR devices. Companies like Phocuswright plan to use such technology in order to expose the lesser known but beautiful areas of the planet, and in turn, increase tourism. Other companies such as Matoke Tours have already developed an application where the user can see 360 degrees from several different places in Uganda. Matoke Tours and Phocuswright have the ability to display their apps on virtual reality headsets like the Samsung VR and Oculus Rift.
AR systems such as Word Lens can interpret the foreign text on signs and menus and, in a user's augmented view, re-display the text in the user's language. Spoken words of a foreign language can be translated and displayed in a user's view as printed subtitles.
Leeds College of Music teams have developed an AR app that can be used with Audient desks and allow students to use their smartphone or tablet to put layers of information or interactivity on top of an Audient mixing desk.
ARmony is a software package that makes use of augmented reality to help people to learn an instrument.
In a proof-of-concept project Ian Sterling, interaction design student at California College of the Arts, and software engineer Swaroop Pal demonstrated a HoloLens app whose primary purpose is to provide a 3D spatial UI for cross-platform devices — the Android Music Player app and Arduino-controlled Fan and Light — and also allow interaction using gaze and gesture control.
AR Mixer is an app that allows one to select and mix between songs by manipulating objects – such as changing the orientation of a bottle or can.
In a video, Uriel Yehezkel demonstrates using the Leap Motion controller and GECO MIDI to control Ableton Live with hand gestures and states that by this method he was able to control more than 10 parameters simultaneously with both hands and take full control over the construction of the song, emotion and energy.[better source needed]
A novel musical instrument that allows novices to play electronic musical compositions, interactively remixing and modulating their elements, by manipulating simple physical objects has been proposed.
A system using explicit gestures and implicit dance moves to control the visual augmentations of a live music performance that enable more dynamic and spontaneous performances and—in combination with indirect augmented reality—leading to a more intense interaction between artist and audience has been suggested.
Research by members of the CRIStAL at the University of Lille makes use of augmented reality in order to enrich musical performance. The ControllAR project allows musicians to augment their MIDI control surfaces with the remixed graphical user interfaces of music software. The Rouages project proposes to augment digital musical instruments in order to reveal their mechanisms to the audience and thus improve the perceived liveness. Reflets is a novel augmented reality display dedicated to musical performances where the audience acts as a 3D display by revealing virtual content on stage, which can also be used for 3D musical interaction and collaboration.
Augmented reality is becoming more frequently used for online advertising. Retailers offer the ability to upload a picture on their website and "try on" various clothes which is overlaid on the picture. Even further, companies such as Bodymetrics install dressing booths in department stores that offer full-body scanning. These booths render a 3-D model of the user, allowing the consumers to view different outfits on themselves without the need of physically changing clothes. For example, JC Penney and Bloomingdale's use "virtual dressing rooms" that allow customers to see themselves in clothes without trying them on. Another store that uses AR to market clothing to its customers is Neiman Marcus. Neiman Marcus offers consumers the ability to see their outfits in a 360 degree view with their "memory mirror". Makeup stores like L'Oreal, Sephora, Charlotte Tilbury, and Rimmel also have apps that utilize AR. These apps allow consumers to see how the makeup will look on them. According to Greg Jones, director of AR and VR at Google, augmented reality is going to "reconnect physical and digital retail."
AR technology is also used by furniture retailers such as IKEA, Houzz, and Wayfair. These retailers offer apps that allow consumers to view their products in their home prior to purchasing anything. IKEA launched their IKEA Place at the end of 2017 and made it possible to have 3D and true to scale models of furniture in their living space, through using the app and their camera. IKEA realized that their customers are not shopping in stores as often or directly buy things anymore. So they created IKEA Place to tackle these problems and have people try out the furniture with Augmented Reality and then decide if they want to buy it.
Snapchat users have access to augmented reality in the company's instant messaging app through use of camera filters. In September 2017, Snapchat updated its app to include a camera filter that allowed users to render an animated, cartoon version of themselves called "Bitmoji". These animated avatars would be projected in the real world through the camera, and can be photographed or video recorded. In the same month, Snapchat also announced a new feature called "Sky Filters" that will be available on its app. This new feature makes use of augmented reality to alter the look of a picture taken of the sky, much like how users can apply the app's filters to other pictures. Users can choose from sky filters such as starry night, stormy clouds, beautiful sunsets, and rainbow.
The Dangers of AR
There is a danger that will make individuals overconfident and put their life at risk because of it. Pokémon GO with a couple of deaths and many injuries is the perfect example of it. "Death by Pokémon GO”, by a pair of researchers from Purdue University's Krannert School of Management, says the game caused “a disproportionate increase in vehicular crashes and associated vehicular damage, personal injuries, and fatalities in the vicinity of locations, called PokéStops, where users can play the game while driving.”. The paper extrapolated what that might mean nationwide and concluded “the increase in crashes attributable to the introduction of Pokémon GO is 145,632 with an associated increase in the number of injuries of 29,370 and an associated increase in the number of fatalities of 256 over the period of July 6, 2016, through November 30, 2016.” The authors valued those crashes and fatalities at between $2bn and $7.3 billion for the same period.
Furthermore, more than one in three surveyed advanced internet users would like to edit out disturbing elements around them, such as garbage or graffiti. They would like to even modify their surroundings by erasing street signs, billboard ads, and uninteresting shopping windows. So it seems that AR is a threat to companies as it is an opportunity. Although this could be a nightmare to numerous brands that do not manage to capture consumer imaginations it also creates the risk that the wearers of augmented reality glasses may become unaware of surrounding dangers. Consumers want to use augmented reality glasses to change their surroundings into something that reflects their own personal opinions. Around two in five want to change the way their surroundings look and even how people appear to them.
Next, to the possible privacy issues that are described below, overload and over-reliance issues is the biggest danger of AR. For the development of new AR related products, this implies that the user-interface should follow certain guidelines as not to overload the user with information while also preventing the user to overly rely on the AR system such that important cues from the environment are missed. This is called the virtually-augmented key. Once the key is not taken into account people might not need the real world anymore.
The concept of modern augmented reality depends on the ability of the device to record and analyze the environment in real time. Because of this, there are potential legal concerns over privacy. While the First Amendment to the United States Constitution allows for such recording in the name of public interest, the constant recording of an AR device makes it difficult to do so without also recording outside of the public domain. Legal complications would be found in areas where a right to a certain amount of privacy is expected or where copyrighted media are displayed.
In terms of individual privacy, there exists the ease of access to information that one should not readily possess about a given person. This is accomplished through facial recognition technology. Assuming that AR automatically passes information about persons that the user sees, there could be anything seen from social media, criminal record, and marital status.
Privacy-compliant image capture solutions can be deployed to temper the impact of constant filming on individual privacy.

- Francisco Delgado is a NASA engineer and project manager specializing in human interface research and development. Starting 1998 he conducted research into displays that combined video with synthetic vision systems (called hybrid synthetic vision at the time) that we recognize today as augmented reality systems for the control of aircraft and spacecraft. In 1999 he and colleague Mike Abernathy flight-tested the LandForm system aboard a US Army helicopter. Delgado oversaw integration of the LandForm and SmartCam3D systems into the X-38 Crew Return Vehicle. In 2001, Aviation Week reported NASA astronaut's successful use of hybrid synthetic vision (augmented reality) to fly the X-38 during a flight test at Dryden Flight Research Center. The technology was used in all subsequent flights of the X-38. Delgado was co-recipient of the National Defense Industries Association 2004 Top 5 software of the year award for SmartCam3D.
