This paper describes which auditory information affects the accuracy of "perception of crossability" for blind people. We have created a "virtual 3D acoustic environment" in which subjects feel a car passing in front of them to help them cross a road safely. The system is theoretically based on acoustic "time-to-contact" information, which is the most important concept in Ecological Psychology. Experimental results suggest that blind people tend to estimate the acoustic "time-to-contact" significantly longer than did sighted people. However, there are no significant differences between their sensitivities toward the speed of a moving sound source and the gain level of indirect sounds. [ABSTRACT FROM AUTHOR] |
