- CaBot (Carry-on Robot, Carnegie Mellon Suitcase Robot)
- A research project begun in 2017 at Carnegie Mellon University that developed a suitcase-shaped autonomous navigation robot to guide blind and low-vision travellers through indoor public spaces. CaBot…
- ChamBadge (Chambadge)
- A wearable accessible cell phone device developed as part of the Talking Braille ubiquitous computing system for indoor wayfinding. The ChamBadge combines a cell phone with a bone-conduction headset, …
- Cyber Crumb (Digital Crumb, Electronic Breadcrumb)
- A concept in accessible wayfinding where tiny, inexpensive solar-powered digital chips are placed along building walkways like a trail of breadcrumbs, storing location-specific information that can be…
- HULOP (Human-scale Localization Platform)
- An open-source indoor navigation platform originally developed by IBM Research to support blind navigation using Bluetooth Low Energy (BLE) beacon fingerprinting for localisation plus a topological ma…
- Indoor Localization (Indoor Positioning, Indoor Positioning System, IPS)
- The problem of determining the precise location of a person or device inside a building, where GPS signals are weak or unavailable. Indoor localization is foundational for accessible wayfinding system…
- 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,…
- Infrared (IR, Infrared Communication)
- A wireless communication technology that uses infrared light to transmit data over short distances, commonly used in assistive technology for line-of-sight data exchange between devices. In accessibil…
- Intersection Detection (Junction detection, Corridor intersection recognition)
- A computer-vision or sensor-fusion technique used in indoor navigation systems for blind travellers to identify where two or more walkable corridors meet, so the navigation software can update the use…
- Narrative Route Description (Verbal Route Guidance, Turn-by-Turn Narrative)
- A structured verbal representation of a travel route that guides users through sequential steps using spoken or text-based instructions. Effective narrative descriptions for blind travelers typically …
- Node Map (Topological node map, Graph map)
- A graph-based representation of a walkable space in which each node corresponds to a meaningful point — typically an intersection, a destination (room, exit, stairwell), or the user's current position…
- RSSI Fingerprinting (Received Signal Strength Fingerprinting, Radio Fingerprinting, Signal Fingerprinting)
- An indoor localization technique in which a device estimates its position by comparing the current pattern of received signal strengths (RSSI) from surrounding radio sources — most commonly Bluetooth …
- 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…
- Soundscape (Auditory Soundscape, Audio Landscape)
- An auditory environment where multiple spatialized sounds represent objects or landmarks in all directions around a listener, creating an acoustic representation of physical space. In accessibility ap…
- Suitcase Robot (Suitcase-shaped robot, Robotic suitcase)
- A class of autonomous navigation robots housed inside a rolling suitcase or carry-on-shaped enclosure, designed so that a blind or low-vision user can grip the handle and be guided to a destination wh…
- Ultra-Wideband (UWB, Ultra wideband)
- A short-range radio-frequency technology that uses very wide frequency bands (typically above 500 MHz) and very short pulses to enable centimetre-accurate distance and angle-of-arrival measurements be…
- Wi-Fi Fingerprinting (WiFi Fingerprinting, Wi-Fi Positioning)
- An indoor localization technique that estimates a device's position by comparing the signal strengths of nearby Wi-Fi access points against a pre-collected database of "fingerprints" — measurements ta…
- ZigBee (IEEE 802.15.4)
- A low-power, low-data-rate wireless networking protocol based on the IEEE 802.15.4 standard, designed for short-range communication between devices in personal area networks. In accessibility and assi…
