Navigation of blind and visually impaired people

Kurzfassung

The mobility of the blind and visually impaired is associated with many barriers and risks. To secure crossings, signalized intersections are partially equipped with acoustic or tactile indicators. However, environmental conditions might interfere with the acoustic identification of the green time. Furthermore, information such as intersection topology, bicycle traffic or the curb structure is not accessible to visually impaired road users. Therefore, most trips are limited to trained routes. Within the research project InMoBS (intra-urban mobility support for the blind and visually impaired) a prototype of a route planning and navigation system has been developed and evaluated in an exploratory manner.
