Abstract(in English) The ventriloquism effect has been studied in only around subject′s just ahead field. In this report, we investigated that the difference threshold of audiovisual target in peripheral field. As the result, the threshold angle in peripheral field was larger than that in front. That is to say, the audiovisual target with spatial distance in peripheral field is easier to be regarded as in same position than that in front. And we attempted to expand visible filed when we use a head mounted display by compressing vision horizontally, and tried to maintain the sense of direction by using sound images.It was suggested that the sense of direction in a compressed visual field can be maintained by using a sound image up to about 25% compression ratio.
