AR (Augmented Reality)
AR is an enhanced version of reality where live direct or indirect views of physical real-world environments are augmented with superimposed computer-generated images.
Marker-based AR
Marker-based AR uses a camera and a visual marker to determine the center, orientation, and range of interaction of the augmented content.
Markerless AR
Markerless AR, also known as location-based or position-based AR, uses GPS, gyroscopes, accelerometers, and digital compasses to provide data based on location.
AR SDK
An AR Software Development Kit (SDK) is a set of software tools and libraries that allows developers to create AR applications.
SLAM (Simultaneous Localization and Mapping)
SLAM is a computational method used in AR that allows devices to map an environment and simultaneously track their own movement within it.
AR Glasses
AR glasses are wearable devices that overlay digital content onto the user's field of vision.
Mixed Reality (MR)
Mixed Reality is a blend of physical and digital worlds, unlocking natural and intuitive 3D human, computer, and environment interactions.
Haptic Feedback
Haptic Feedback refers to any tactile feedback given to the user through vibrations or motions, enhancing the realism of the AR experience.
Head-Mounted Display (HMD)
A head-mounted display is a wearable device that has a small display optic in front of one (monocular) or each eye (binocular).
Fiducial Marker
A fiducial marker is a physical reference that is used in the field of AR to help devices detect and track the position and orientation of objects.
Augmented Reality Cloud (ARCloud)
ARCloud is a persistent 3D digital copy of the physical world to enable shared AR experiences across different devices and users.
Occlusion in AR
Occlusion in AR is a technique used to render virtual objects behind real-world objects, enhancing the perception that they coexist in the same space.
Plane Detection
Plane Detection is a feature in AR systems that allows the device to detect flat surfaces in the environment to place virtual objects.
AR Visualization
AR Visualization refers to the process of displaying digital images and information superimposed onto the real world that a user sees.
Image Recognition in AR
Image Recognition in AR involves the identification of objects, places, signs, or other items within the camera's field of view to trigger AR content.
