Abstract:
This paper presents our work on developing, implementing and evaluating a multimodal interactive guidance system that features spoken language and touch-screen input for elderly persons. The development foundation of the system comprises two systematically designed and empirically improved aspects: a set of development guidelines for elderly-friendly multimodal interaction according to common ageing-related decline of important human abilities, and a hybrid dialogue modelling approach with a formal method triggering and agent-based management for the elderly-centered multimodal interaction. To evaluate the minutely developed and implemented system, an experimental study was conducted with thirty-three elderly persons and empirical data were analyzed by applying an adapted version of a general evaluation framework, which provided overall positive analysis results and validated our effort to develop an effective, efficient and elderly friendly multimodal interaction.
