Dialog Support for Totally Deafblind Persons by Conveying Back-channels through Vibration
نویسندگان
چکیده
We conducted an experiment using a vibration system using which a totally deafblind participant, communicating through an interpreter, could directly receive back-channel feedback from a conversational partner. Statistical analysis of the interaction structure showed that the back-channel vibration increased the participant’s turn-taking ability and interactivity during the communication. Moreover, from a qualitative analysis of the video data, we found that the experience of receiving back-channel feedback caused a change in his haptic behavior with respect to that during normal communication. Our results indicate that the low mental workload and learnability of this vibration system allows deafblind persons to improve their communication. In parallel with the experiment using a vibrator, we conducted a questionnaire survey among the interpreters, questioning them on their interpretation behavior.

The World Health Organizaion (WHO) states that 15 percent of world population are with disabilities. Deafblindness is a combination of vision and hearing impairments. There are a few people who are completely deaf and blind. Our world is organised around hearing sighted people, and this can present many challenges to a deafblind person. If you have little or no sight and hearing, learning to co...
