First steps towards a recognition of ADLs with radio modules

The paper describes a system, designed for unsupervised detecting and recording the activities of daily living (ADL) of patients with mild cognitive impairment (MCI) without human observation. Many miniaturized, radio linked and mobile μC-based tags are used. Some are fixed to objects others are carried by the patients. All tags have a limited and adjustable communication range. Basic concept is to detect, to record and to analyze the combinations of μC-tags. This paper deals especially with a first user interface to evaluate the ADL of a patient as well as an evaluation of our system over several days for some activities with a sensitivity of 92%. This is the last step before entering a clinical environment.
