BLINDTRACK: Guiding system for visually impaired - locating system for running on a track

Visually impaired people need to renounce several social activities what the sighted people can enjoy. In this paper we refer to the project BLINDTRACK which has the major goal to develop a guidance system. A real-time locating system (RTLS) based on radio signals guides the runners with the highest level of safety by estimating the angle of arrival (AoA) and round-trip time (RTT). First results show the position accuracy of the proposed locating system with real-world data. BLINDTRACK provides an enormous freedom for the visually impaired runners in compare to the other solutions: Sighted and blind runners will have the opportunity to perform sport together without another person's assistance.
