- Assistive Drone (Assistive UAV, Assistive Quadcopter)
- A small unmanned aerial vehicle configured to assist a person with a disability — most often a blind or low-vision user — with tasks such as locating objects, navigating unfamiliar environments, scann…
- Chart Question Answering (Chart QA, ChartQA, Visual Question Answering for Charts)
- The task of answering natural-language questions about a data visualization, typically a chart provided as an image or structured specification. A chart question answering system must identify the cha…
- Depth Estimation (Monocular Depth Estimation, Depth Prediction)
- The computer vision task of predicting the distance from the camera to each point in a scene, producing a depth map in which each pixel carries a distance value. Monocular depth estimation uses a sing…
- Embodied Exploration
- An approach to virtual environment interaction in which the user builds understanding of a space by physically walking, turning, reaching, and sweeping rather than by teleporting or using controller-b…
- Mixed-Visual Ability (diverse visual abilities, mixed-visual-ability team)
- Mixed-visual ability refers to teams or workplace settings that include members with a range of visual abilities, including sighted individuals, people with low vision, and people who are blind. The c…
- Mobile Virtual Reality (Mobile VR, Smartphone VR)
- Virtual reality systems delivered through a smartphone and consumer-grade accessories (wireless headphones, simple hand-held mounts) rather than a dedicated head-mounted display and PC rig. For access…
- OrCam (OrCam MyEye, OrCam Read)
- A family of wearable assistive devices made by OrCam Technologies that use a camera and on-device AI to read printed text aloud, identify faces and products, and recognize colors and banknotes for bli…
- Pedestrian Navigation (Pedestrian Wayfinding, On-Foot Navigation)
- Pedestrian navigation refers to wayfinding and route-following on foot in outdoor environments, including sidewalks, crosswalks, public transit access points, and shared streets. For blind and low vis…
- Product Identification (Product Recognition)
- The task of determining what a packaged or unpackaged product is from visual (or other sensory) input, at a level of detail useful to an end user: generic type (soup, cereal, shampoo), brand (Campbell…
- Robotic Guide Dog (Robot Guide Dog, Quadruped Guide Robot)

- Semantic Scene Graph (SSG, scene graph)
- A semantic scene graph is a structured data representation of a 3D or 2D environment that encodes objects, their properties (such as position, size, color, and audio characteristics), and the spatial …
- Social Wayfinding (Social Navigation Assistance)
- Social wayfinding refers to the capacity to perceive and navigate the dynamics of a social scene, not just its physical layout. It covers identifying who is present, where they are oriented, whether t…
- Spatial Reasoning
- The cognitive process of understanding where objects are, how they are oriented, and how they relate to each other in three-dimensional space. Spatial reasoning is central to tasks like assembling pro…
- 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…
- Tactile Authoring (Tactile Graphic Authoring, BLV Authoring)
- The creation of tactile graphics — raised-line drawings, swell-paper images, or refreshable-display renderings — by or with blind and low-vision authors, rather than exclusively by sighted experts. Ta…
- Vibro-Audio Map (VAM, Vibro-Audio Display)
- A multimodal map representation for touchscreen devices that combines vibrotactile feedback with synchronised audio cues to convey spatial information non-visually. Users explore the map by dragging a…
- Video-to-Haptics (Video to Haptics, V2H)
- A class of techniques that automatically generate haptic feedback (typically vibrotactile or force cues) from visual content in video, so that viewers feel sensations synchronised with what they see. …
- Vista Space (Vista)
- In Montello's classification of psychological spaces, a Vista is a far-field space that can be visually apprehended from a single vantage point without appreciable locomotion - a horizon view, a city …
