Abstract

The paper presents tests of a remote guidance system for the blind. The idea behind the system is to relay a video stream from a camera carried by a blind person to a remote operator who can provide assistance based on the video and the GPS position of the blind user. The remote operator helps the blind traveller by short spoken instructions. The connection is established over the GSM network using High-Speed Downlink Packet Access data transfer. The aim of the paper is to present the performance of the system in an urban area. The study includes discussion about communication link reliability, GPS accuracy and camera resolution. Three tests were conducted: guiding the user in a university campus and helping him to cross the street and locate a tram. Tests shows that the system is useful and has great potential, albeit further improvements are necessary.
