How RollSense turns a ride into route memory
RollSense combines motion and location measurements from an active wheelchair ride to describe where surface conditions changed and help riders remember how a route felt.
1. Mount the phone securely
The phone must be fixed securely to the wheelchair or mobility device. A stable mounting position helps RollSense distinguish movement from the route surface from movement caused by holding or repositioning the phone.
2. Start an active ride
Recording begins only after the rider starts a ride. During that active session, RollSense synchronizes GPS location with accelerometer and gyroscope measurements. Recording ends when the rider finishes the ride.
3. Translate movement into route context
The recorded signal is processed to identify relative vibration, repeated irregularities, and stronger impacts along the route. Device and mounting context matter, so the result is designed as a rider-specific view rather than a universal pavement score.
RollSense is currently in early closed beta. Sensor calibration and surface estimations are still being tested and refined with real rides.
4. Keep a personal route memory
Completed rides become a private history that can help a rider recall and compare route experiences. The planned Community Map is not active during the current closed beta, and beta ride data is not published to a public community map.
What RollSense does not claim
RollSense does not guarantee that a route is accessible, safe, obstacle-free, or suitable for every wheelchair user. Surface comfort is only one part of route suitability, and riders should continue to consider traffic, gradients, crossings, weather, construction, and their own mobility needs.
