VIRTUAL AUDITORY SPACE FOR VISUALLY IMPAIRED – METHODS FOR TESTING VIRTUAL SOUND SOURCE LOCALIZATION

Abstract

This article deals with issue of virtual sound source positioning for the purposes of acoustic navigation in unknown spaces and extends our research published last year. Navigation experiment was based on using PERSEUS assistive device. No appropriate standards in the field of performing subjective localization a navigation tests can be found. Our methods of design and evaluation of the listening and navigation tests are proposed and discussed. The following text is considered as an overview with references to our previous articles, which contain more detailed info.
