Abstract
Finger Braille is one of the tactual communication methods utilized by deaf blind individuals. Deaf blind people who are skilled in Finger Braille can catch up with speech conversation and express various emotions by changing dotting strength and speed. In this paper, the emotion teaching interface in order to express joy, sadness and anger for the Finger Braille emotion teaching system were designed. Three combinations of the background colors and dot patterns for each emotion, 12 kinds of teaching interfaces with different background colors or dot patterns, and 5 kinds of the other teaching interfaces which did not associate any emotions were designed. The experiment to evaluate the most suitable emotion teaching interfaces for joy, sadness and anger was conducted. The results showed that the dot pattern 1 (the small circle) with the yellow or dark orange background colors are suitable for joy, the dot pattern 7 (the narrow and long pattern) with the lavender or blue background colors are suitable for sadness, the dot pattern 9 (the large circle) with the red background color are suitable for anger.
