Paper Abstract

We propose navigational aid systems for the blind relying on active laser profilometry and infrared proximetry with a real time vibrotactile interface. The Teletact and the Vigitact are small hand held or badge worn devices to improve the spatial perception, the mobility and the security of blind people. The Teletact is a hand held laser telemeter and gives an accurate 3D spatial perception up to ten meters. The Vigitact is an infrared scanner and provides an automatic vigilance from knees to head up to two meters. Both devices are now commercially available. We will report on the basic functional parts of these devices, the results of everyday use by blind people, and future technological improvements.
