Abstract
About possibilities of the radiation of the auditory signal for walking by the blind, this study describes a side that blind people generate continual regulation to approach targets and destinations by adjustments of their body toward the speaker emitted the auditory signal. In subway stations, KAIGAN-line in Kobe, we observed that two blind persons approached the ticket gate with the radiation of the auditory signals. Based on their oriented locomotion in the structure near the ticket gate, they explored the turning place to the ticket gate by adjusting their steps and turning their head toward the radiation of the auditory signal without reaching the junction of tactile tiles. These adjustments do not always need to discriminate the indication as a signal. The random radiation by setting the auditory signal is a potential target for continual regulation to approach in preference to learning the auditory indications.
