Augmented reality (AR) is an interactive experience that combines the real world and computer-generated 3D content. The content can span multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects. The overlaid sensory information can be constructive, or destructive. As such, it is one of the key technologies in the reality-virtuality continuum.
Motion capture is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots. In films, television shows and video games, motion capture refers to recording actions of human actors and using that information to animate digital character models in 2D or 3D computer animation. When it includes face and fingers or captures subtle expressions, it is often referred to as performance capture. In many fields, motion capture is sometimes called motion tracking, but in filmmaking and games, motion tracking usually refers more to match moving.
A fiducial marker or fiducial is an object placed in the field of view of an image for use as a point of reference or a measure. It may be either something placed into or on the imaging subject, or a mark or set of marks in the reticle of an optical instrument.
ARToolKit is an open-source computer tracking library for creation of strong augmented reality applications that overlay virtual imagery on the real world. Currently, it is maintained as an open-source project hosted on GitHub.
In computing, 3D interaction is a form of human-machine interaction where users are able to move and perform interaction in 3D space. Both human and machine process information where the physical position of elements in the 3D space is relevant.
Wikitude was a mobile augmented reality (AR) technology provider based in Salzburg, Austria. Founded in 2008, Wikitude initially focused on providing location-based augmented reality experiences through the Wikitude World Browser App. In 2012, the company restructured its proposition by launching the Wikitude SDK, a development framework that uses image recognition and tracking, and geolocation technology.
Vuforia is an augmented reality software development kit (SDK) for mobile devices that enables the creation of augmented reality applications. It uses computer vision technology to recognize and track planar images and 3D objects in real time. This image registration capability enables developers to position and orient virtual objects, such as 3D models and other media, in relation to real world objects when they are viewed through the camera of a mobile device. The virtual object then tracks the position and orientation of the image in real-time so that the viewer's perspective on the object corresponds with the perspective on the target. It thus appears that the virtual object is a part of the real-world scene.
Metaio GmbH was a privately held augmented reality (AR) company that was acquired by Apple Inc. in May 2015. Headquartered in Munich, Germany, with subsidiaries in San Francisco, California, New York City, New York, and Dallas, Texas, Metaio provided a software development kit (SDK) for programming PC, web, mobile applications, and custom offline augmented reality applications. Additionally, Metaio was the creator of Junaio, a free mobile AR browser available for Android and iOS devices.
WebAR, previously known as the Augmented Web, is a web technology that allows for augmented reality functionality within a web browser. It is a combination of HTML, Web Audio, WebGL, and WebRTC. From 2020s more known as web-based Augmented Reality or WebAR, which is about the use of augmented reality elements in browsers.
The Augmented Reality Markup Language (ARML) is a data standard to describe and interact with augmented reality (AR) scenes. It has been developed within the Open Geospatial Consortium (OGC) by a dedicated ARML 2.0 Standards Working Group. ARML consists of both an XML grammar to describe the location and appearance of virtual objects in the scene, as well as ECMAScript bindings to allow dynamic access to the properties of the virtual objects, as well as event handling, and is currently published in version 2.0. ARML focuses on visual augmented reality.
Tango was an augmented reality computing platform, developed and authored by the Advanced Technology and Projects (ATAP), a skunkworks division of Google. It used computer vision to enable mobile devices, such as smartphones and tablets, to detect their position relative to the world around them without using GPS or other external signals. This allowed application developers to create user experiences that include indoor navigation, 3D mapping, physical space measurement, environmental recognition, augmented reality, and windows into a virtual world.
Blend4Web is a free and open source framework for creating and displaying interactive 3D computer graphics in web browsers.
Microsoft HoloLens is an augmented reality (AR)/mixed reality (MR) headset developed and manufactured by Microsoft. HoloLens runs the Windows Mixed Reality platform under the Windows 10 operating system. Some of the positional tracking technology used in HoloLens can trace its lineage to the Microsoft Kinect, an accessory for Microsoft's Xbox 360 and Xbox One game consoles that was introduced in 2010.
Experience Curiosity is an interactive web application developed by NASA's Jet Propulsion Laboratory to celebrate the third anniversary of the Curiosity rover landing on Mars. This 3D serious game makes it possible to operate the rover, control its cameras and the robotic arm and reproduces some of the prominent events of the Mars Science Laboratory mission. The application was presented at the beginning of the WebGL section at SIGGRAPH 2015.
In virtual reality (VR) and augmented reality (AR), a pose tracking system detects the precise pose of head-mounted displays, controllers, other objects or body parts within Euclidean space. Pose tracking is often referred to as 6DOF tracking, for the six degrees of freedom in which the pose is often tracked.
ARCore, also known as Google Play Services for AR, is a software development kit developed by Google that allows for augmented reality (AR) applications to be built. ARCore has been integrated into a multitude of devices.
Verge3D is a real-time renderer and a toolkit used for creating interactive 3D experiences running on websites.
Commercial augmented reality (CAR) describes augmented reality (AR) applications that support various B2B (Business-to-Business) and B2C (Business-to-Consumer) commercial activities, particularly for the retail industry. The use of CAR started in 2010 with virtual dressing rooms for E-commerce.
NASA's Eyes Visualization is a freely available suite of computer visualization applications created by the Visualization Technology Applications and Development Team at NASA's Jet Propulsion Laboratory (JPL) to render scientifically accurate views of the planets studied by JPL missions and the spacecraft used in that study. The Eyes family of products is available for desktop computers running Windows 7+, and Mac OSX 10.8+. Deep Space Network Now and Experience Curiosity are web-based and available across all platforms. 3D models of spacecraft and other objects are displayed with the option of comparing their size to a human, school bus, or football stadium.
The Augmented Reality Sandtable (ARES) is an interactive, digital sand table that uses augmented reality (AR) technology to create a 3D battlespace map. It was developed by the Human Research and Engineering Directorate (HRED) at the Army Research Laboratory (ARL) to combine the positive aspects of traditional military sand tables with the latest digital technologies to better support soldier training and offer new possibilities of learning. It uses a projector to display a topographical map on top of the sand in a regular sandbox as well as a motion sensor that keeps track of changes in the layout of the sand to appropriately adjust the computer-generated terrain display.
