Recognition of interactions with objects based on radio modules

In this contribution a novel system for the recognition of interaction with objects is presented. The developed system iActionlogger (interActionlogger) consists of radio modules that are used to recognize contact situations between a user and an object and is meant as a monitoring tool for users activities. Worldwide a great effort is done in developing technologies that allow elderly people to live independent and yet secure in their home environment for as long as possible. The recognition of Activities of Daily Living (ADLs) is an important point in order to evaluate the overall health status of a person. At this time no technology could win through to be the tool to reliably work in a realistic environment. In this paper we compare some of the existing technologies and evaluate our approach in respect to technical and user demands.
