Outline of Final Research Achievements |
With the aim of guaranteeing the right to go out for visually impaired people, a prototype for a "verbal tourist guide" that virtually reproduces the environmental sounds heard when walking in accordance with voice directions and town guidance was created through experiments in which the person concerned was the test subject. Directions and town guidance by voice use the GPS function of the smartphone to provide guidance according to the situation sequentially. In addition, before going to the site, there is also a mode to prepare for the predetermined course at home etc. The environmental sound when walking is processed from on-site recordings with a video camera and provided according to the simulated walking conditions. These are integrated like a tourist guidebook and compiled into a video format form as a "verbal tourist guide."

Academic Significance and Societal Importance of the Research Achievements |
街歩きを疑似体験してもらう場合の課題は、第一に歩行路周辺の物的環境について納得し、安心してもらうことである。自動車の走行音や、周辺歩行者の足音、沿道の商店の呼び込みの声などの環境音について、視覚障碍者はこれまでの体験と照合して、納得できて初めて疑似歩行が開始できる。 第二に、より広範囲の位置関係が明確にならないと、街歩きの実感は得られない。晴眼者が略図や、鳥観図、航空写真等で面的な配置を確認するのと同様のことが、視覚障碍者にも保障されなければならない。 上記の二つの課題に対するひとつの解答を本研究で得た。学術的には視覚障害者の空間認知に関わる知見の拡充、社会的には外出権保障としての意義を持つ。
