| 抄録: | Visually impaired people have difficulties in perceiving environmental information
including the size of a space and the presence of objects, by means of visual information. Particularly,
auditory-trained visually impaired people can recognize 3-D spatial information by
means of environmental sounds. However, a systematic learning method of auditory spatial
perception for walking training has not been sufficiently established because of insufficient information
regarding visually impaired people’s movement in the real environment; most acquire
this ability through practical experience. In this report, the authors aimed at demonstrating the
mobility of visually impaired people, for example, which acoustical factors can be used in some
living situations and in what kind of environmental situations do they find it difficult to perceive
silent objects. Results indicated the following facts: Totally visually impaired people tend to
get more spatial information from auditory cues than do not-totally visually impaired people.
Regarding available auditory cues, items of rotating the head in order to listen carefully to environmental
sounds, and hitting floors forcefully with a white cane or foot to increase the volume
of reflected or reverberated sounds were the cues most often selected by the totally visually
impaired participants who can perceive obstacles with auditory information. |
