Design Research Of VR Platform Of Lower Limp Rehabilitation Robot Based On User Experience

Lower limb rehabilitation robot can simulate the law of lower limb movement during normal walking,and provide continuous,symmetrical walking training for patients with lower limb dysfunction,and improve the efficiency of rehabilitation training while reducing the physical burden of the rehabilitation.Virtual reality technology can generate virtual scenes,and help users build a sense of immersion,and then establish the nerve stimulation from the brain to the affected limb through the visual channel.This topic has obtained the development status of lower limb rehabilitation robots and virtual reality technology through data review,questionnaire survey and interviews,establishing spatial interface design rules for lower limb rehabilitation robots by constructing user portraits and analyzing user physiological and psychological characteristics.Analyzing software,hardware,and operation methods,combining experiments to find a more suitable operation for patients with lower limb dysfunction.Research is guided by the theory of user experience factors,according to the decision order of strategy,scope,structure,skeleton and surface,from concept to concrete,summed up the virtual space interface design process for lower limb rehabilitation robots.Through the KANO model in the design process,the functions that are more in line with the user's needs are selected and ranked by importance.Drawing on the design rules of the mobile terminal and the PC interface,the virtual space is built based on the user's operational behavior habits,and the learning cost of the user is reduced.Making low-fidelity interactive prototypes for usability testing in Beijing Rehabilitation Hospital Rehabilitation Treatment Room using wireframe drafts during the design process,mining the usability,usability issues of design products and suggesting improvements to ensure a better user experience.This topic realized the interaction between users,interfaces and virtual scenes by building a virtual reality platform,emphasized patient initiative and added fun to the patient's training process.The research finally formed a set of virtual reality platform interface with rehabilitation training as the core task process,Summarized a complete virtual reality space interface design method suitable for lower limb rehabilitation,and expanded the application of virtual reality technology in the field of rehabilitation.
