Finger Braille is one of the tactual communication methods utilized by deafblind individuals. Deafblind 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, we designed the emotion teaching interface in order to express joy, sadness, anger and neutral for the Finger Braille emotion teaching system. We changed the previous background color (beige) of the teaching interface into 17 different colors. We also designed 8 kinds of dot patterns with different horizontal width and vertical length. The experiment to select the most suitable emotion teaching interfaces for joy, sadness, anger and neutral was conducted. The results showed that the dot patterns 6 (the wide and middle length pattern) or 1 (the small circle) with the lime, dark orange or yellow background colors are suitable for joy; the dot patterns 7 (the narrow and long pattern) or 4 (the narrow and middle length pattern) with the lavender, navy or blue background colors are suitable for sadness; the dot patterns 9 (the large circle) or 8 (the middle width and long pattern) with the red background color are suitable for anger; the dot pattern 5 (the middle circle) with the previous, honeydew, saddle brown or white background colors are suitable for neutral.
