“How Would You Communicate With a Robot?”: People with Neourodevelopmental Disorder's Perspective

Neurodevelopmental disorders (NDDs) are charac-terised by impairments in communication. Socially assistive robots have been identified as a promising avenue to alleviate their burden. Since NDDs have different needs, their way of communicating with a robot (e.g., speech-based) could differ among individuals. This paper aims to investigate the most suitable modality to communicate with a robot for NDDs - among voice, cards, and buttons - and explore their opinion on this matter. We ran an exploratory study involving 29 NDDs participants: 13 of them could freely communicate with an autonomous QT robot, 9 took part in a group discussion, and 7 first interacted individually with the robot, and then they participated in a group discussion. Our results showed that i) the cards were the most used communication modality, ii) voice can be used for counting games, buttons for multiple-choice games, and cards for memory-like games, iii) opinions did not differ much among groups.*
