[Invited] Auditory perceptual world in people with visual impairments

<p>Support systems have been developed to facilitate the active participation of the visually impaired, as the impairment limit information acquisition and activities. However, efforts to improve the quality and quantity of information presented to persons with disabilities are still in the developmental stage due to the unique perception and recognition styles in persons with visual impairment. By clarifying such perception and recognition mechanisms and the current status of assistive technologies, researchers can develop support schemes taking advantage of the abilities of people with visual impairment, and extend their information processing. Therefore, the purpose of this presentation is to organize the unique characteristics of perceptual ability and communication strategies reportedly acquired by persons with visual and hearing impairments and the information assurance methods based on sensory substitution. Particularly, this talk includes a visual substitution system that focuses on sound and tactile information, in addition to their sensory substitution functions, and example applications through support methods in parasports and computer games. The content of this talk is based on the articles written by the author [1], [2] .</p>
