Chikamune Wada · 2009
Most electronic travel aids for the visually impaired and blind persons use voice instruction to inform the device users of the distance to the destination. However, presentation method of voice instruction have not been designed by taking into account the specific characteristics of human cognition, and so users sometimes would be confused. Then, in this paper, we would like to investigate optimal presentation method. From the results, we proposed a new distance-presentation method by voice instruction and revealed its efficacy.
