Suitability of a Common ZigBee Radio Module for Interaction and ADL Detection

Abstract

In this contribution we analyze whether it is possible to use a ZigBee module to detect interactions. The detection is done using modules with adjustable communication range. From the data we want to draw conclusions about the activities of daily living (ADL). This is important to detect because small changes in behavior which might indicate the beginning of dementia or a mild cognitive impairment. We have already done promising experiments with a radio module. In this paper we analyze whether it is also possible to use a common ZigBee module. Therefore we compare it with the module we used already and then modify the antenna to shorten the range. Our findings show that it is possible to use the ZigBee module for interaction and ADL detection by adjustable range after modifications in the antenna circuit.
