The MOBOT rollator human-robot interaction model and user evaluation process

Abstract

In this paper we discuss the integration of a communication model in the MOBOT assistive robotic platform and its evaluation by target users. The MOBOT platform envisions the development of cognitive robotic assistant prototypes that act proactively, adaptively and interactively with respect to elderly humans with slight walking and cognitive impairments. The respective multimodal action recognition system has been developed to monitor, analyze and predict user actions with a high level of accuracy and detail. The robotic platform incorporates a human-robot communication model that has been defined with semantics of human actions in interaction, their capture and their representation in terms of behavioral patterns, to achieve an effective, natural interaction, aiming to support elderly users of slight walking and cognitive inability. The platform has been evaluated in a series of validation experiments with end users, the procedure and results of which are also presented in this paper.
