We present an empirical study that is being conducted in the context of developing a GPS locating system for individuals with Alzheimer's disease (AD) in Germany. A disposition of wandering is one of the most problematic symptoms as it fosters anxiety, disorientation and can even lead to life-threatening situations. Our qualitative empirical study contributes to the research on social phenomena which reveals some technical implications for the development of location-based services (LBS) in dementia care. We demonstrate that common concepts such as the dilemmas "awareness vs. privacy" in general and "safety vs. autonomy" in the context of monitoring systems for wandering patients need to be tackled from practice-based views. Our study attempts to understand caregivers' practices and attitudes towards these concepts.
