- Accessible Pedestrian Signal (APS, Audible Pedestrian Signal, Talking Traffic Signal)
- A traffic control device that communicates pedestrian signal information in non-visual formats, typically through audible tones, speech messages, or vibrating surfaces, enabling blind and visually imp…
- Accessible Routing (Accessible Navigation, Barrier-Free Routing, Accessible Wayfinding)
- The calculation of travel routes that account for accessibility barriers and the specific mobility needs of disabled pedestrians. Unlike standard navigation that optimises solely for distance or time,…
- Adaptive Navigation (Adaptive Navigation Support)
- A technique in which a system dynamically modifies the presentation of navigational elements (such as links, menus, or breadcrumbs) based on user characteristics, behaviour, or context. In accessibili…
- 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…
- Audio-Based Navigation (Audio Navigation, Auditory Navigation)
- A navigation approach that uses audio output — typically synthesised speech, spatial audio cues, or sonification — as the primary means of providing wayfinding information to users. Audio-based naviga…
- Bluetooth Beacons (BLE Beacons, iBeacons, Bluetooth Low Energy Beacons)
- Small wireless transmitters that use Bluetooth Low Energy (BLE) to broadcast signals to nearby smartphones and other devices. In accessibility contexts, Bluetooth beacons are deployed in indoor enviro…
- Cell Navigation (Table Cell Navigation, Cell-by-Cell Navigation)
- Cell navigation is a method of accessing tabular data non-visually by moving between individual cells using directional commands (up, down, left, right). Rather than reading a table linearly from top-…
- Clock Technique (Clock Method, Clock Face Direction System)
- An orientation method used in mobility training for blind and visually impaired people in which directions are communicated using the positions on an analogue clock face. The user imagines standing at…
- Cognitive Map (Cognitive Mapping)
- An internal mental representation of spatial relationships within an environment, formed through direct experience, exploration, or learning from maps and descriptions. Cognitive maps allow people to …
- Community Navigation (Community Travel, Community Mobility)
- The ability to plan, initiate, and complete trips within one's community, including getting to transit points on time, using public transportation, and accessing services at destinations. For people w…
- Crosswalk (Pedestrian Crossing, Zebra Crossing, Continental Crossing)
- A marked area on a roadway designated for pedestrians to cross safely, typically indicated by painted lines or patterns on the pavement. Zebra crossings (called "continental crossings" in the US) feat…
- Digital Compass (Electronic Compass, Magnetometer)
- An electronic sensor that detects the Earth's magnetic field to determine the direction a person or device is facing, providing heading information in degrees or cardinal directions. In assistive tech…
- Environmental Flow (Optic Flow, Sensory Flow)
- The ordered changes in a pedestrian's distances and directions to surrounding objects that occur while walking, providing continuous feedback about spatial position and movement through the environmen…
- Floor Plan (Floor Map, Building Plan, Building Layout)
- A floor plan is a scaled diagram of a room or building viewed from above, showing the arrangement of rooms, corridors, exits, and other spatial features. In accessibility contexts, floor plans present…
- Hamburger Menu (Hamburger Icon, Menu Icon)
- A UI pattern using three stacked horizontal lines (☰) to hide and reveal a primary navigation menu, most commonly on mobile interfaces. Accessibility considerations include the need for an accessible …
- Indoor Positioning System (IPS)
- A technology system that determines the location of people or objects inside buildings where GPS signals are unavailable or unreliable. Indoor positioning systems use various technologies including Wi…
- Inertial Sensing (IMU sensing, Inertial measurement)
- The use of accelerometers, gyroscopes, and magnetometers — often built into smartphones and wearable devices — to measure motion, orientation, and direction of movement. In accessibility applications,…
- Landmark-Based Navigation (Landmark Navigation, Landmark-Based Wayfinding)
- A wayfinding strategy that uses recognisable environmental features such as buildings, signs, or other prominent objects as reference points for giving directions, rather than relying solely on street…
- Last Meter Problem (Last Mile Problem, Final Approach Problem)
- In assistive technology for blind users, the challenge of bridging the gap between knowing an object exists and physically reaching or interacting with it. While object detection apps can identify wha…
- Link Annotation (Link Augmentation, Link Labelling)
- The practice of adding supplementary information to hyperlinks to help users make informed navigation decisions before clicking. In web accessibility, link annotations may include the accessibility le…
