BraillePath, a Station-Navigation Proposal for Chennai
An interactive concept note for offline-first metro guidance designed for blind and low-vision passengers.
Field notes
BraillePath describes a proposed station-navigation stack rather than a currently available passenger app. Its route guidance would combine BLE anchors, phone-sensor estimates and downloadable station packs, with audio, screen-reader, refreshable-braille and haptic outputs. The submission proposes testing the system across three Chennai stations with 75 blind and low-vision passengers, then measuring route completion, travel time, assistance, confidence and technical reliability. The page also specifies a USD 450,000 grant request and USD 50,000 in co-financing.
