- Location Awareness (Location-Aware Computing, Location Sensing)
- The ability of a computing system to determine and respond to the physical location of a user or device, typically using GPS, Wi-Fi positioning, cellular triangulation, or other sensing technologies. …
- Macro-Navigation (Macro Navigation)
- The process of navigating through the broader environment at the level of routes, streets, landmarks, and destinations — knowing where you are in a city, which direction to travel, and how to reach a …
- Map Accessibility (Accessible maps)
- The practice and field of making maps — digital geovisualizations, online navigation maps, tactile maps, and physical signage — perceivable, operable, understandable, and robust for users with disabil…
- Micro-Navigation (Micro Navigation)
- The process of navigating the immediate environment — detecting and avoiding obstacles, following the edge of a pavement, identifying surface changes, and maintaining a safe path. For blind and visual…
- Navigation Axis (Multi-Axial Navigation, Axis-Based Navigation)
- A navigation axis is a concept from screen reader research describing a specific linear serialization of a subset of web page elements that represents one navigation strategy. Rather than forcing blin…
- Pedestrian Navigation System (Pedestrian GPS, Walking Navigation)
- A navigation system designed specifically for people travelling on foot, as opposed to systems designed for car drivers. Pedestrian navigation systems must account for footpaths, crosswalks, stairs, p…
- Pseudo-Attraction Force
- A haptic illusion technique that creates the sensation of being pulled or pushed in a specific direction by exploiting the nonlinear relationship between physical and perceived acceleration. The techn…
- Robotic Guide Dog (Robot Guide Dog, Quadruped Guide Robot)
- A mobile robot — typically a quadruped platform — designed to provide navigation and obstacle-avoidance support for blind and low-vision users, filling a role analogous to that of a trained guide dog.…
- Route Planning (Journey Planning, Pre-Journey Planning)
- The process of determining a path from an origin to a destination before travel begins, including selecting roads or paths, identifying landmarks and decision points, and considering factors such as s…
- Signal Fingerprinting (Wireless Fingerprinting, RF Fingerprinting, Bluetooth Fingerprinting)
- Signal fingerprinting is a technique used in indoor positioning systems where the unique pattern of wireless signal strengths (such as Bluetooth, Wi-Fi, or RFID) at specific locations within a buildin…
- Social Robot Navigation (Socially-aware robot navigation, Social navigation)
- A subfield of robotics concerned with how a mobile robot should move through environments shared with humans — choosing paths, speeds, and timings that respect social norms as well as physical obstacl…
- Spatial Navigation (Spatial Orientation, Spatial Wayfinding)
- The cognitive process of determining and following a route from one location to another, involving the ability to remain oriented, recall routines, recognize landmarks, and make decisions at choice po…
- Spindex (Speech Index)
- An auditory navigation technique that uses the first letter of each word (spoken or synthesized) as an index to speed up list navigation. When scrolling through alphabetically ordered lists like conta…
- Surface Level Change (Elevation Change, Grade Change)
- Any change in the height of the ground or floor surface, including stairs, curbs, ramps, steps, potholes, and raised thresholds. Surface level changes are a significant mobility challenge and safety h…
- Tactile Dome (Truncated Dome, Detectable Warning Surface)
- Small raised bumps arranged in a grid pattern on ground surfaces to provide a tactile warning of an upcoming hazard, such as a curb edge, train platform edge, or street crossing. Tactile domes are par…
- Trajectory Analysis (Route Analysis, Path Analysis)
- The computational study of movement patterns over time and space, typically derived from GPS or other location data. Trajectory analysis involves modelling, comparing, and classifying sequences of spa…
- Veering (Lateral Drift)
- The tendency of blind and visually impaired pedestrians to gradually drift away from a straight path while walking, resulting in a curved trajectory rather than a direct line. Veering is a well-docume…
- 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…
- Voicemark (Voice Bookmark, Audio Bookmark)
- A navigable audio marker or bookmark that allows users to quickly locate and access specific sections of web content or documents through speech or keyboard interaction. Voicemarks are created by anal…
