Towards an ambient assisted living user interaction taxonomy

Extensive research in the field of ambient assisted living (AAL) provides profound knowledge about the design of AAL systems. However, more generic design characteristics for user interaction have not been formalized for this domain yet. Thus, we propose to develop a domain specific taxonomy for the design of user interaction in AAL systems. We adopted a systematic taxonomy development approach that combines an empirical and a pseudo-conceptual strategy. Six co-researchers from different disciplines conduct the iterative research process. Next to AAL systems existing taxonomies in the field of human-computer interaction are analyzed following the Delphi method. In this paper we present our research process and preliminary results from the first iteration. The final taxonomy allows classification and should support the analysis of user interaction utilized in AAL systems. Furthermore, it can deal as a practical design guideline.
