What Communication Modalities Do Users Prefer in Real Time HRI?
This work addresses modality preferences for users in human-robot interaction, but it is incremental as it focuses on a specific experimental setup without broader SOTA impact.
The study investigated user preferences for communication modalities (voice, guiding touch, visual demonstration) in a real-time human-robot interaction task involving teaching a robot to mime a nursery rhyme, finding no preference in human effort but significant differences in enjoyment and marginal differences in perceived robot imitation ability.
This paper investigates users' preferred interaction modalities when playing an imitation game with KASPAR, a small child-sized humanoid robot. The study involved 16 adult participants teaching the robot to mime a nursery rhyme via one of three interaction modalities in a real-time Human-Robot Interaction (HRI) experiment: voice, guiding touch and visual demonstration. The findings suggest that the users appeared to have no preference in terms of human effort for completing the task. However, there was a significant difference in human enjoyment preferences of input modality and a marginal difference in the robot's perceived ability to imitate.
