Augmented reality From Walked, the free encyclopedia Jump to: navigation, search Wickerwork Browser the phone guess Expands a solid state compass Singularly AR SD markers tracker used in the AR Debarred (Androids) AR Tower Defenseless on the Monika Microphones (Symbiosis) uses fiduciary markers Augmented reality(AR) is a live, direct or indirect, view of a physical, real- world environment whose elements are augmented(or supplemented) by computer- considerateness’s Input such as sound, video, graphics or Sparta.
It is related to a more general concept called mediated reality, In which a view of reality Is modified possibly even dullness rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of contrast, virtual realistically the real world with a simulated is conventionally in real-demand in semantic context with environmental elements, such as sports scores on TV during a match. With the help of advanced AR technology (e. G. Adding computer visional object recognition) the information about the surrounding real world of the user becomes interactive digitally manipulate.
Head-mounted A head-mounted display(HEM) is a display device paired to a headset such as a harness or helmet. Hams place images of both the physical world and virtual objects over the user’s field of view. Modern Hams often employ sensors for six degrees of preconditioning that allow the system to align virtual information to the physical world and adjust accordingly with the user’s head movements. Hams can provide users immerse, mobile and collaborative AR experiences.  Eyeglasses AR displays can be rendered on devices resembling eyeglasses.
Versions include eye ear that employ cameras to intercept the real world view and re-display its augmented view through the eye piecesand devices in which the AR imagery is projected through or reflected off the surfaces of the eye wear lens 5] Google Glasses not intended for an AR experience, but third-party developers are pushing the device toward a mainstream AR an existing app for smartness, applies algorithms and triangulation techniques to photo metadata including GAPS position, compass heading, and a time stamp to arrive at a relative significance value for photo technology can be seed by Google Glass users to learn where to look at a give point in time.  Contact lenses Contact lenses that display AR imaging are in development. These bionic contact lengthiest contain the elements for display embedded into the lens including integrated circuitry, Leeds and an antenna for wireless communication.  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.   Virtual retinal display A virtual retinal display(IVR) is a personal display device under development at the University of Washington’s Human Interface Technology Laboratory. With this technology, a display is scanned directly onto the retinal a viewer’s eye. The viewer Tappet The Tappet(also known as Generation-2 Glass) captures rays of light that would otherwise pass through the center of a lens of an eye of the wearer, and substituted each ray of light for synthetic computer-controlled light.
The Generation-4 Glass (Laser Tappet) is similar to the IVR (I. E. It uses a computer controlled laser light resource) 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 resentments (in laser light) of rays of light entering the eye.  Handheld Handheld displays employ 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 fiduciary markers,and later Subunits and Misdemeanors such as digital compasses and six degrees of predetermination’s-gyroscope.
Today Salamanders trackers such s PTA 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 is the portable nature of handheld devices and 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 distorting effect of classically wide-angled mobile phone cameras when compared to the real world as viewed through the eye.

Nun 2013) Spatial Augmented Reality(SARA) augments real world objects and scenes without the use of special displays such as monitors, head mounted displays hand-held devices. SARA makes use of digital projectors to display graphical information onto physical objects. The key difference in SARA is that the display is separated from the users of the system. Because the displays are not associated with each user, SARA scales naturally up to groups of users, thus allowing for collocated collaboration teen users. Examples include shaded lamps, mobile projectors, virtual tables, and smart projectors.
Shaded lamps mimic and augment reality by projecting imagery onto neutral objects, providing the opportunity to enhance the object’s appearance with Other tangible applications include table and wall projections. One such 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 n 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. Spatial AR does not suffer from the limited display resolution of current head- mounted displays and portable devices.
A projector based display system can simply incorporate more projectors to expand the display area. Where portable devices have a small window into the world for drawing, a SARA system can display on any number of surfaces of an indoor setting at once. The drawbacks, however, are that SARA yester of projectors do not work so well in sunlight and also require a surface on which to project the computer-generated graphics. Augmentations cannot simply hang in the air as they do with handheld and HEM-based AR. The tangible nature of SARA, though, makes this an ideal technology to support design, as SARA supports both a graphical visualization and passive hyphenations for the end users.
People are able to touch physical objects, and it is this process that provides the passive hepatic Tracking Modern mobile augmented reality systems use one or more of the following tracking cosmologies: digital cameraman’s/or other optical sensors, accelerometers, GAPS, gyroscopes, solid state compasses, Ruffian wireless sensors. These technologies offer varying levels of accuracy and precision. 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 DOFF interaction technique.  Input devices Techniques include speech recontaminations that translate a user’s spoken words into computer instructions and gesture recontaminations that can interpret a user’s body movements by visual detection or from sensors embedded in a Raphael device such as a wand, stylus, pointer, glove or other body wear. 37] Computer The computer analyzes the sensed visual and other data to synthesize and position augmentations. 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’s uses different methods of computer vision, mostly related to video tracking. Many computer vision methods of augmented reality are inherited from visual odometer. Usually those methods consist of two parts. First detect interest points, or fiduciary markers, or optical flowing the camera images.
First stage can use feature disconnections like corner detection, blob detection, edge detection troubleshooting/or other image prestidigitation. 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 fiduciary markers) present in the scene. In some of those cases the scene AD structure should be overpopulated beforehand. If part of the scene is unknown simultaneous collocation and mapping(SLAM) can map relative positions. If no information about scene geometry is available, structure from motionless like bundle adjustment used.
Mathematical methods used in the second stage include projective(bipolar) geometry, geometric algebra, rotation representations exponential map, Oklahoman particularities, nonlinear optimization, robust statistics. Applications Augmented reality has many applications, and many areas can benefit from the use of AR technology. AR was first used for military, industrial, and medical applications, UT was soon applied to commercial and entertainment areas.  Archaeology AR can be used to aid archaeological research, by augmenting archaeological features onto the modern landscape, enabling archaeologists to formulate conclusions about site placement and configuration. 46] Another application given to AR in this field is the possibility for users to rebuild ruins, buildings, or even landscapes as they formerly existed.  Architecture structure can be superimposed into a real life local view of a property before the physical building is constructed there. AR can also be employed within an architect’s ark space, rendering into their view animated AD visualization of their AD 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.  Art AR technology has helped disabled individuals create art by using eye tracking translate a user’s eye movements into drawings on a screen. 50]An item such as a commemorative coin can be designed so that when scanned by an AR-enabled device it displays additional objects and layers of information that were not visible in real world view of 2013, L’Oreal used Crowding technology to create an augmented reality at the seventh annual Illuminant Festival in Toronto, Canada.  Commerce Viewer BUTLERS App – Placing furniture using AR 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. 54]AR is used to integrate print and video arresting. 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 Construction With the continual improvements to Supremacy, businesses are able to use augmented reality to visualize correspondence’s of construction sites, underground structures, cables and pipes using mobile devices. Following the Christopher earthquake, the University of Canterbury released, Activities, which enabled city planners and engineers to visualize buildings that were destroyed in the earthquake. 0]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 were demolished. App ‘Skull, an augmented human skull for education (SHOOS) Augmented reality applications can complement a standard curriculum. Text, graphics, video and audio can be superimposed into a student’s real time environment. Textbooks, flashcards and other educational reading material can contain embedded “markers” that, when scanned by an AR device, produce supplementary information to the student rendered in a multimedia format. 61] Students can participate interactively with computer generated simulations of historical events, exploring and learning details of each significant area of the event site. 64]AR can aid students in understanding chemistry by allowing them to visualize the spatial structure of a molecule and interact with a virtual model of it that appears, in a camera image, positioned at a marker held in their hand. Augmented reality technology also permits learning via remote collaboration, in which students and instructors not at the same physical location can share a moon virtual learning environment populated by virtual objects and learning materials and interact with another within that setting.  Everyday 30 years of Augmented Reality in everyday life. Since the sass and early sass, Steve Mann has been developing technologies meant for everyday use I. E. Horizontal” across all applications rather than a specific “vertical” market. Examples include Man’s “Tappet Digital Eye Glass”, a general- purpose seeing aid that does dynamic-range management (HAD vision) and overlays, underlay’s, simultaneous augmentation and admonishment (e. G. Diminishing the electric arc while looking at a welding torch).  Gaming Marcher’s mobile game Get On Targets a trigger image as fiduciary marker Augmented reality allows gamers to experience digital game play in a real world environment. In the last 10 years there has been a lot of improvements of technology, direct detection of the player’s movements. 68] Industrial design AR can help industrial designers experience a product’s design and operation before completion. Volkswagen uses AR for comparing calculated and actual crash test imagery. AR can be used to visualize and modify a car body structure and engine Toyota. AR can also be used to compare digital mock-ups with physical mock-ups for finding discrepancies between Medical Augmented Reality can provide the surgeon with information, which are otherwise hidden, such as showing the heartbeat rate, the blood pressure, the state of the patient’s organ, etc. AR can be used to let a doctor look inside a patient by combining one source of images such as an X-arrhythmia another such as video.
Examples include a virtual X-reinvade based on prior tomography on real time images from ultrasound conceal microprocessoror visualizing the position f a tumor in the video of an endoscope. AR can enhance viewing a fetidness a mother’s womb. See also Mixed reality. Military 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 3600 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.  Navigation
Augmented reality map on phone 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. 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. Office workplace AR can help facilitate collaboration among distributed team members in a work force IA conferences with real and virtual participants.
AR tasks can include brainstorming and discussion meetings utilizing common visualization via touch screen tables, interactive digital whiteboards, shared design spaces, and distributed control rooms. Sports and entertainment 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 footballers 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 Ridgefield and crotchetiness 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. AR can enhance concert and theater performances. For example, artists can allow listeners to augment their listening experience by adding their performance to that of other bands/groups of users.  The gaming industry has benefited a lot from the development of this technology. A number of games have been developed for prepared indoor environments. Early AR games also include AR air hockey, collaborative combat against virtual enemies, and an AR-enhanced pool games.
