With the Tablet and smart phone development, the development of mobile applications (mobile Apps) has become more desirable and diversified in users’ perspective. In this study, an Android Apps was developed for an outpatient physical therapy clinic. The purpose of this handheld healthcare information system is to record medical processes and patient appointment. Our research starts with a special mobile App developed for the physical therapy room to assist therapists in an outpatient rehabilitation clinic at one medical center in New Taipei City. Currently, only paper-based system is available to keep records on patients’ appointments and treatment history. With the proposed system, therapists are able to query patients’ treatment histories in a timely manner. Whenever a patient arrives, the system would try to assign this person to rehabilitation equipment that is required by this patient’s treatment plan with shortest waiting list as the capacity is allowed. It is also possible to let therapists to fine tune the assignment and reallocate equipment as needed. Later, different scenarios are used to demonstrate the use of this Android App and the interaction between system and the therapist. The major benefits for using this system includes: (1) the ability to assist therapists to find an efficient way to allocate resources to patients, and (2) the ability to display an overview on total arrived patients and the dynamic of waiting lists for treatment resources.
