- 3D Reconstruction (Scene Reconstruction, 3D Scene Reconstruction)
- The computer vision task of recovering the 3D structure of a scene - geometry, camera positions, and sometimes object trajectories - from one or more 2D images or video frames. Techniques range from c…
- Attention Tunneling (Visual Tunneling, Attentional Tunneling, Cognitive Tunneling)
- A phenomenon in which a user concentrates so narrowly on a primary information source - typically a visual overlay, head-up display, or instrument - that they fail to notice relevant events, objects, …
- Audio Augmented Reality (Audio AR, Augmented Audio Reality, Audio-Augmented Environment)
- The overlay of digital sound — synthesised speech, music, earcons, or spatialised audio cues — onto a user's perception of their real or virtual environment. Audio augmented reality can be head-worn (…
- Gesture Interaction (Gesture-based interaction, Gestural interfaces)
- An input modality in which users control digital systems through hand, arm, or body movements detected by cameras, depth sensors, IMUs, or wearable devices rather than through traditional keyboards, p…
- Gorilla Arm (Gorilla-arm effect, Gorilla arm syndrome)
- A well-documented ergonomic phenomenon in which sustained unsupported arm elevation — typical of mid-air touchscreen, vertical display, or extended reality (XR) gesture interaction — produces rapid sh…
- Mobile AR (Smartphone AR, Handheld AR)
- Augmented reality experiences delivered on commodity smartphones and tablets using the built-in camera, display, inertial sensors, and (increasingly) depth sensors, without specialized AR headsets. Mo…
- Networked Minds Social Presence Inventory (Networked Minds Measure of Social Presence, NMSPI)
- The Networked Minds Social Presence Inventory is a self-report questionnaire developed by Biocca, Harms and colleagues to measure social presence - the sense of 'being together' with another person - …
- Proteus Effect
- The Proteus Effect is a phenomenon, first described by Yee and Bailenson (2007), in which the appearance of a person's avatar influences how they think, behave and interact in virtual or augmented env…
- Spatial Computing (Spatial interaction)
- A paradigm of computing in which digital content is rendered and interacted with in three-dimensional physical space, typically via head-worn augmented or mixed reality devices (e.g., HoloLens, Magic …
- Spatialization (Spatialisation, Audio Spatialization, 3D Audio Spatialization)
- The process of rendering a sound so that it appears to originate from a specific location in three-dimensional space around the listener. Spatialization typically combines head-related transfer functi…
- USDZ (Universal Scene Description Zip)
- A 3D file format based on Pixar's Universal Scene Description (USD), packaged as a zip archive so a single file can carry meshes, textures, materials, and animations. USDZ is the default 3D asset form…
- Visual-Inertial Odometry (VIO)
- A computer vision technique that combines camera imagery with motion sensor data (accelerometer and gyroscope) to track a device's position and orientation in 3D space. In accessibility applications, …
