Abstract
With the rapid transition into an ageing society for various countries, health care services aimed for elderly people, namely elderly care, are more and more important and attract attention from governments. Since the fast-growing of the smartphones and the popularization of location-based services, nowadays, more diverse services can be provided for elderly people. In this paper, we propose a concept of community-based walking trail sharing service, which is aimed at middle- and old-aged people, to encourage them to go outside. This system lets elderly people utilize smartphone easily to acquire their favorite pictures or walking information, and share the data with the server in the public place. Through our system, the users not only can share their information each other but also be able to receive suggestions or recommendations about walking trails from system server. By the recommendations, the users can find their potential friends who have same interests or hobbies, or obtain different walking trails for try. It is expected that the proposed service will make elderly people to express themselves, join more activities, and keep interact with people. As a result, the elderly people can maintain their healthy physically or mentally.
