Pedestrian Detection(also: Person Detection, Human Detection)

A computer vision task that identifies and locates people in images or video frames, typically using deep learning models such as convolutional neural networks. In accessibility applications, pedestrian detection is used in wearable assistive technologies for blind and low…

Pedestrian Navigation(also: 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 vision users, people with cognitive disabilities, and wheelchair users, the…

Personal Space(also: Interpersonal Distance, Personal Distance Zone)

The invisible boundary surrounding a person that they consider their own territory, the violation of which can cause discomfort or stress. Research by Edward T. Hall defined four distance zones: intimate (0-18 inches), personal (18 inches to 4 feet), social (4-12 feet), and…

Physical Guidance(also: Hands-On Guidance, Physical Assistance)

A body movement teaching technique in which an instructor physically moves or positions a student's body to demonstrate correct form, rhythm, or placement. Physical guidance is widely used in teaching dance, sports, and martial arts to blind and low vision students, as it…

Presentation Accessibility(also: Slide Accessibility, Accessible Presentations)

The practice of designing and delivering slide-based presentations so that all audience members, including those with disabilities, can access the content. Key principles include verbally describing all visual content on slides (text, images, diagrams, graphs), using nouns…

Procedural Feedback System(also: Process-Oriented Guidance System)

An assistive technology paradigm that provides dynamic, step-by-step support throughout complex multi-step tasks rather than addressing isolated moments of need. Unlike traditional assistive tools that help with discrete actions (e.g., identifying a color or reading a label),…

Product Identification(also: 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's, Kellogg's, Dove), and variety or flavour (tomato vs. chicken noodle; 90%…

Proprioception(also: Proprioceptive Sense, Body Position Sense)

The body's ability to sense its own position, movement, and orientation in space without relying on vision. Proprioceptive information comes from sensory receptors in muscles, tendons, and joints that detect stretch, tension, and pressure. For people who are blind or have low…
