In recent years, healthcare is a hot topic. One of the important areas in healthcare is rehabilitation. This research focuses on hand rehabilitation for the elderly, adults, and children. Many studies were carried out using exercise games such as running game to aid in rehabilitation. However, in our research we will explore and experiment with new user engaging devices and user-interface techniques for serious games. Hopefully, we can derive new design models for doing so. The discovery of these design approaches will be fundamental and transformative as they can be used in other applications.
