摘要：Visually impaired persons typically visualize graphical information through the tactile sensation of a pin matrix display. Unfortunately, the panel of a pin matrix display has a small gross area, the size of a postcard, so it is hard for several people to touch the panel and share the same information concurrently. Moreover, while the display is suitable for presenting a static figure, it is difficult to visualize a moving image with one's fingers. To solve these problems, we focused on the resolution of time in the sense of hearing, and conducted research on using sound from speakers arranged in a matrix to present both static and moving figures that can be shared by several people simultaneously. This paper describes an experiment we conducted to determine whether people could recognize the stroke order of the uppercase alphabet. Sound was broadcast from the various matrix speakers as if it were moving. Participants had a high average for correctly recognizing the alphabetic characters, demonstrating that people are able to recognize graphical information transmitted as moving sound.
