Abstract
Rehabilitation is a therapy that needs to receive continuously to see the effect of treatment. Patients not only need to do rehabilitation exercise in hospital, but also keep themselves in practice at home. One of the major difficulties that physical therapists is that the supply for rehabilitation medical service is unable to meet its patients. The other difficulty is that the therapists are unable to immediately grasp how effective the home rehabilitation exercise works. Another issue is no way to grasp the progress of the home exercise. The imbalance between the supply and demand for the rehabilitation service is becoming more serious. Information communications technology (ICT) can be solved the problems and be able to improve the quality of the medical service. While motion-sensing detecting and image recognition technologies are getting mature, and the accuracy of tracking skeleton motion can be used for evaluating the accuracy of the movement. More and more studies focus on how to use the ICT to assist rehabilitation exercise, to improve the effect, and to reduce the cost of rehabilitation. Through the interactive design, users are more willing to execute programs, thus rehabilitation effects are enhanced. The software design can change the traditional rehabilitation service, which easily make users bored, and can reduce the patient’s resistance to perform rehabilitation therapy. Researchers consider the virtual rehabilitation system can reduce treatment costs, include the human resource and financial ones, due to its affordable building cost and its success compliance and disease assessments, which truly meet the medical criteria. This study uses the patent literature as a resource for technological discussions and applies the patent analysis to find out the macro viewpoints of the current system development. This research also analyzes the features and patent portfolio of the products on the market. Finally, the study analyzed a real system and its patent portfolio, and the diffusion of the relative technologies and their business model point of view.
