Interactive medicine case system for elderly recipient

In Japan, the number of elderly recipients who take medicines regularly has been increasing due to population aging. Since they sometimes induce serious accidents caused by incorrect dosing, we propose iMec System to promote correct dosing. The system is composed of iMec (intelligent medicine case), Ubiquitous Sensors, iMec Server, and Home Robot. iMec recognizes the types and quantities of medicines which a recipient has picked up, estimates whether the recipient is in the living states corresponding to common dosing timings by using Ubiquitous Sensors, and evaluates the dosing adequacy about type, quantity and timing. Ubiquitous Sensors, which are distributed wireless sensors, measure the position of the recipient and the condition of house appliances. iMec Server provides a medication monitoring interface by accumulating the adequacy and send emergency e-mail to caretakers if the adequacy is incorrect. And, Home Robot assists the recipient in correct dosing by its gestures and sounds. We used background subtraction method for confirming the dosages and simple Fuzzy inference algorithm for confirming the timings. We confirmed that iMec System was able to confirm the timings by experiments.
