Haptic Empathy: Conveying Emotional Meaning through Vibrotactile Feedback

Touch plays an essential role in communicating emotions and intensifying interpersonal communication[4]. A lot of research focuses on how to create or improve haptic interfaces looking into challenges and possibilities that the haptic technology can offer[30]. The objective of this research is to investigate whether people can share subjective feelings through simple vibrotactile feedback. In an initial experiment, we used the TECHTILE toolkit[19] to record 28 vibration sample sets for 4 different emotions (joy, anger, sadness, relaxation). We then replayed the vibrations to test how well they could be recognized. The results support the hypothesis that people can use vibration feedback as a medium for expressing specific subjective feelings. It also indicates some universalities in affective vibrotactile stimuli that even strangers with little to no knowledge about the senders could recognize the emotional meanings.
