abstract="Blind persons mostly depend upon walking sticks are seeing eye dog's when walking in urban areas. One way to facilitate their walking is to guide them along a walking path by means of sound signals.  Few studies however have been made on the effects of such signals on blind pedestrians.  This paper analyzes the results of various experiments conducted on three kinds of walking -- straight walking, turning, and obstacle avoidance -- in order to find out the basic features of the effects of sound signals on the walking of the blind.<p />",
