Abstract

The Traveller is a multi-function device to aid blind people in unassisted walking. It provides 4 inter-related functions: (1) A magnetic compass, marked in braille to help a blind person orient himself, or to face and walk in a selected direction. (2) A straight-walker to guide the blind person to walk in a selected direction, using vibrators in the neck-strap at the side of the neck. (3) An obstacle alarm to signal the blind person that an obstacle is ahead at nearer that the pre-selected distance, using a vibrator at the back of the neck. (4) A queue-minder using a vibrator at the back of the neck, to signal the blind person while standing in a queue that the person in front has moved up.
