Abstract:
This paper presents a multimodal interactive guidance system for elderly persons for the use in navigating in hospital environments. We used a unified modelling method combining the conventional recursive transition network based approach and agent-based dialogue theory to support the development of the central dialogue management component. Then we studied and specified a list of guidelines addressing the needs of designing and implementing multimodal interface for elderly persons. As an important step towards developing an effective, efficient and elderly-friendly multimodal interaction, the spoken language interface of the current system was evaluated by an elaborated experiment with sixteen elderly persons. The results of the experimental study are overall positive and provide evidence for our proposed guidelines, approaches and frameworks on interactive system development while advising further improvements.
