Water, one of the most vital materials of our body, comprises 70% of it, 90% of our blood, 75% of our muscles and 85% of our brains. Every system in our body depends on water. According to the doctor’s advice, each people should drink more than 2000 c.c. water to maintain the regular works in our body. However, people never used to calculate how much water or tea they drank before, and almost people don’t know they drink too less water.

This drinking-water supply system turns a technology into an unaware service. With the RFID tags on each glass, we could know which glass belong to whom. In turn, we can sum up the amount of water that the user drinks. In this way, we can remind the users to take the proper amount of water, so the body can keep a good metabolism.

水，在我們的生命中佔有極為重要的角色!

我們的血液中，有90%是水，肌肉中有75%，而在大腦中則有85%，在在都顯示出水份對維持人類身體運作的重要性。醫學報告指出，建議每人每天應飲用超過2000c.c.的水，以讓我們身體的各機能運作正常；然而，人們卻很少認真的看待這個議題，甚至大部分的人根本不知道他們並沒有攝取到一天該飲用的水量。

多數人在固定的活動場所會有固定使用的水杯或飲水容器，這組供水裝置配合附有RFID標籤的個人杯子可以區辨哪位使用者(杯子)前來裝水，並計算使用者當天所累積的飲水量是多少，透過上述的機制本設計表現出科技提供服務於無形、利用科技關懷使用者的觀念，提醒使用者為了身體健康每人每天應攝取2000 c.c.以上的水，以保持良好的新陳代謝。
