- ARKit (Apple ARKit)
- ARKit is Apple's augmented reality development framework for iOS that enables developers to create AR experiences for iPhone and iPad. It uses the device's camera, motion sensors, and processor to det…
- Augmented Reality (AR) (AR, Augmented Reality)
- An interactive technology that overlays digital information — such as text, images, or video — onto the real-world environment in real time. In accessibility contexts, AR has significant potential for…
- Field of View (FoV, Viewing Angle)
- The angular extent of the observable world visible at any given moment. In the context of head-mounted displays like the HoloLens 2, the field of view refers to the area in which virtual content can b…
- Gesture-Based Interaction (Gesture Control, Gestural Input)
- A mode of human-computer interaction where users control digital systems through hand or body movements detected by cameras or sensors, rather than through traditional input devices. In mixed reality …
- Microsoft HoloLens (HoloLens, HoloLens 2)
- A self-contained, optical see-through mixed reality headset developed by Microsoft that overlays holographic content onto the real world. The HoloLens 2 features hand and eye tracking, spatial mapping…
- See-Through Display (Optical See-Through Display, Transparent Display, OST Display)
- A display technology that allows users to view digital content overlaid on the real world by projecting images onto a transparent or semi-transparent surface. Unlike opaque (occlusive) displays that b…
- Shared Augmented Reality (S-AR, Co-Located AR, Collaborative AR)
- An augmented reality setup in which multiple users share a spatially aligned view of virtual content anchored in the same physical environment. Each user wears a head-mounted display and can see and i…
- Spatial Anchor (World Anchor, Azure Spatial Anchor)
- A reference point in physical space used to precisely position and lock virtual content to real-world locations in augmented reality applications. Spatial anchors ensure that virtual objects remain co…
- Tactile Marker (Tactile Anchor, Physical Anchor)
- Physical objects such as coasters, placemats, or textured stickers placed in the environment to provide tactile reference points that help bridge virtual and physical interactions. In AR-based low-vis…
- Visual Inertial Odometry (VIO)
- A motion tracking technique that combines camera-based visual tracking with inertial sensor data (gyroscopes and accelerometers) to estimate a device’s position and orientation in 3D space with high a…
