Shin-ichiro Iwamiya, Katsuya Yamauchi, Kousuke Shiraishi, Masayuki Takada and Masaru Sato
Journal of Physiological Anthropology and Applied Human Science 23 267-271 2004 [Refereed]
The government of Fukuoka City conducted a survey to determine the effectiveness of an audio-guidance system for the blind. The blind participants confirmed the usefulness of the audio-guidance. In addition, the blind participants and the walking instructors also provided various comments and suggestions for the better utilization of audio-guidance systems for smoother transportation. In order ...
A Basic Study on Universal Design of Auditory Signals in Automobiles
Journal of Physiological Anthropology and Applied Human Science 23 295-298 2004 [Refereed]
In this paper, the impression of various kinds of auditory signals currently used in automobiles and a comprehensive evaluation were measured by a semantic defferential method. The desirable acoustic characteristic was examined for each type of auditory signal. Sharp sounds with dominant high-frequency components were not suitable for auditory signals in automobiles. This trend is expedient for...
