Person-environment interaction

Caleb-Solly, Praminda

Abstract

This chapter presents an overview of human-computer interaction and design issues for person-environment interaction that are applied in Ambient Assisted Living (AAL), with consideration of the accessibility needs of people with age-related physical and cognitive impairments when designing interfaces. A review of the recent technologies that have been used to facilitate interaction via different modalities is presented, and the advantages and disadvantages they offer in relation to different physical and cognitive impairments. In addition, this review also considers the impact of stress, attention, social context, user experience and cognitive load on the usability of these technologies within specific AAL scenarios. This chapter also presents some key interaction models and considers how the recent AAL technologies designed for specific application areas can be assessed against these to ensure effectiveness and efficiency of user interaction. This chapter concludes with a set ofbest practice guidelines for designing person- environment interactions in the AAL context.
