WIT, 福祉情報工学}, month = {May}, note = {Information and Communication Technologies (ICTs) have provided a variety of communication services for different user groups. Some mobile phones also have functionality of videophone. These devices are convenient for signed language communication in providing flexibility of time and place of use. In this report we investigate access to signed language by mobile videophone. We conduct an experiment to investigate signed language perception under the condition of spatial resolutions of 37.5, 75, 150dpi, and display sizes of 1, 2, 3, 4, and 6 inches: the subjects repeat the sign stimulus by signing back exactly what had been presented. The signing picture conditions were determined by the combination of 3 spatial resolutions and 5 picture sizes. The results show that percentage of correct accuracy rate decreases significantly by spatial resolution and display sizes decreasing. The results also show that the signed language perception characteristics improvement by increasing spatial resolution despite on smaller display sizes. Moreover, the results show that the perception of hand shape was difficult through all experimental conditions, especially on smaller picture sizes 1 and 2 inches. Certain possible methods for improving communication in signed language via mobile videophone are also discussed.}, pages = {185--188}, title = {手話知覚に対する空間解像度の寄与に関する一検討}, volume = {109}, year = {2009}, yomi = {シオノメ, タケアキ and ワカツキ, ダイスケ} }
