ABSTRACT
There are many electronic devices for the visually impaired but few actually get used on a daily basis. This is due in part to the fact that many devices often fail to address the real needs of the users. In this study, we begin with a review of the existing literature followed by a survey of 54 blind people which suggests that one particular function could be particularly useful in a new device, namely, the ability to localize objects. We have tested the possibility of using a sound rendering system to indicate a particular spatial location, and propose to couple this with a biologically inspired image processing system that can locate visual patterns that correspond to particular objects and places. We believe that such a system can address one of the major problems faced by the visually handicapped, namely their difficulty in localizing specific objects.
