This paper is concerned with the modality of gestures in communication between an intelligent wheelchair and a human user. Gestures can enable and facilitate human-robot interaction (HRI) and go beyond familiar pointing gestures considering also context-related, subtle, implicit gestural and vocal instructions that can enable a service. Some findings of a user study related to gestures are presented in this paper; the study took place at the Bremen Ambient Assisted Living Lab, a 60m2 apartment suitable for the elderly and people with physical or cognitive impairments.
