Indoor Positioning

Technology that determines a person's location within an indoor environment where GPS signals are unavailable or unreliable. Indoor positioning systems use various technologies including BLE beacons, Wi-Fi signal strength, RFID tags, ultra-wideband radio, and computer vision. For accessibility applications, accurate indoor positioning is essential for providing turn-by-turn navigation to people with visual impairments and for routing wheelchair users to accessible paths. The technology underpins accessible indoor wayfinding systems by continuously tracking a user's position relative to points of interest.
