Smartphones, ultra wide band vital to indoor guidance system for the blind

Smartphones and ultra wide band (UWB) technology will be key to a new system to provide indoor support for the blind that's being developed by Japan's National Institute of Information and Communications Technology and Fujitsu. The system uses impulse radio UWB technology in base stations set up throughout an indoor area, as well as for mobile stations, all of which are controlled by a PC. A user's position data is sent via Bluetooth to a smartphone, which can provide audio instructions, including direction and distance. Announcement
