Design Of Amputee Rehabilitation Training System Based On Augmented Reality

The myoelectric control interface can be applied to the control of multifunctional prosthetic hands to help the amputated patient achieve efficient and natural prosthetic control.However,the amputated patients are unable to effectively control the myoelectric prosthesis due to poor quality of EMG signals and lack of training,and the general willingness to use myoelectric prosthesis is still low.The virtual rehabilitation training system can help the amputated patients to carry out efficient rehabilitation training,which has become the current mainstream training program.With the development of virtual reality and augmented reality technology,it is possible to design a virtual training system that is more realistic and participatory.At the same time,the game elements have also been added to the virtual rehabilitation training system to improve the enthusiasm of amputated patients.However,in the current research on the new virtual rehabilitation training system,there is a problem that the system is complicated to use,the versatility is poor,and the actual use experience is not emphasized.There is no ideal new virtual training system.One of the reasons for this situation is that the development of the new virtual training system involves a variety of research directions and technologies,which cannot be independently completed by the researchers on myoelectric control interface.In order to solve the above problems,the main research contents and results of this thesis are as follows:1.Through the investigation of the research status of myoelectric prosthesis and virtual training system,the ideal elements of virtual rehabilitation training system for amputation patients have been analyzed,and then the design of virtual rehabilitation training system based on augmented reality was proposed.Then,the hardware platform for research purposes and home use has been designed and developed.2.In order to solve the problem of collaboration between researchers on myoelectric control interface and researchers or developers on other directions,this thesis has developed a universal software platform for EMG training and testing,which provides researchers with the EMG training and testing experimental research platform,as well as the general user graphical interface.It also provides a common interface for researchers and developers in other research directions.3.To meet the requirements of amputated patients conducting home training and reduce their burden,this thesis has designed and implemented a portable EMG training and testing platform.A cloud platform for storaging and processing of EMG data has also been designed,to provide support for EMG data sharing and remote assisted rehabilitation.4.In order to provide a more participatory training environment for amputated patients,this thesis has implemented an immersive rehabilitation training environment based on augmented reality.This thesis also has realized a multi-degree of freedom virtual hand in the virtual environment,to provide researchers with an experimental platform for conducting researchs like the proportional decoding of EMG.5.In order to reduce the wearing burden of amputee and provide a more interactive and interesting training environment,this thesis has implemented an interactive rehabilitation training environment based on augmented reality,to help amputee “regain the arm”.The training environment has been tested by three amputees and the experimental results proved it effective in improving the effect of EMG training.This thesis also quickly realized two training games,further enhancing the enthusiasm of amputee for rehabilitation training.
