My project is an app design about healthcare, which called Health ProCare. With the increasing of the aging population and the social work intensity, much more people have no time to take care of old people. Also the smart technology has become a part of our lives. So I try to design an app which use smart bracelet to track old people’s health and transform the information into this app, people can achieve long distance take care of the old people. The concept of the app is not to detect the disease, it is about caring. Old people will not sick suddenly, because disease is not a ‘one day work’. The reasons of the disease to old people are the bad lifestyle and unreasonable caring. So this app will try to help people take care of old people every time to have a good life quality and get away form the disease which will make old people have a healthy body.
