Abstract

We propose a novel method for presentation of directional information. The system presents an perception of presence of obstacles by controlling environment sound field. Visual map and voice prompts are practical method for directional information presentation and used in car navigation system. However they occupy sense of sight and hearing. By contrast, our method can present directional information naturally without occupying sensory channels. Therefore, users can get benefits of directional information with enjoying surrounding environment.
