Emotional Communication in Finger Braille

We describe analyses of the features of emotions (neutral, joy, sadness, and anger) expressed by Finger Braille interpreters andsubsequently examine the e ffectiveness of emotional expression and emotional communication between people unskilled in FingerBraille. The goal is to develop a Finger Braille system to teach emotional expression and a system to recognize emotion. The resultsindicate the following features of emotional expression by interpreters. The durations of the code of joy were significantly shorterthan the durations of the other emotions, the durations of the code of sadness were significantly longer, and the finger loadsof anger were significantly larger. The features of emotional expression by unskilled subjects were very similar to those of theinterpreters, and the coincidence ratio of emotional communication was 75.1%. Therefore, it was confirmed that people unskilledin Finger Braille can express and communicate emotions using this communication medium.
