Abstract in English:
The text reports findings of a case study based on the investigation of reminding activities and request practices in the specific context of supported living. These activities turn out to be highly adaptive processes that are embedded in complex assistive networks. The process of reminding and requesting represents a central practice deployed by the assistive institutional and social environment. It suggests to provide a consistent structure that meets individual needs in everyday life of cognitively impaired people. In the light of the development and engineering of assistive technologies we discuss if and how human practices could serve as a basis for modeling an Embodied Conversational Agent (ECA) based assistive system for cognitively impaired people with respect to the adherence of their autonomy.
