Interactive medicine case system for promoting correct dosing

In Japan, the total number of elderly recipients who take medicine regularly has been increasing due to population aging. Since they sometimes induce the serious accidents caused by incorrect medication, we propose iMec System to promote correct medication. The system is composed of iMec (intelligent medicine case), the Ubiquitous Sensors, iMec Server, and the Home Robot. The iMec detects medicine in its storage space and evaluates the adequacy of dose about type, quantity and timing. The Ubiquitous Sensors measures the living activities of a recipient and assists the iMec in confirming the timing. The iMec Server accumulates the adequacy into its database and provides a web interface for telemonitoring. And, the Home Robot warns the recipient of incorrect medication by voices and gestures if the adequacy is low. By using iMec System, caretakers can check the adequacy via the server and can remind the recipient to take medicine. We used background subtraction method for confirming quantity and simple fuzzy inference method for confirming timing. We confirmed that iMec System was able to confirm the quantity and timing by experiments.
