ReVive Usability Evaluation: A Virtual Augmented Reality-Based Content Program for Social Experience of Stroke Rehabilitation Patients

This study aimed to evaluate the usability of the 'ReVive' program, which was designed to improve the social adaptation ability of stroke rehabilitation patients using VR/AR technology. The subjects were 8 rehabilitation patients who had experienced rehabilitation treatment for stroke hemiplegia, spinal cord injury, etc. at a daycare center and a welfare facility for the disabled in Seoul in November 2023 and September 2024. The research method used a combination of quantitative and qualitative evaluation methods such as the program's usability evaluation (SUS), the impact on the daily life of rehabilitation patients (K-DAL), the user experience evaluation (UEQ), and in-depth interviews. The recognition rate of the LeapMotion2 sensor varied depending on the upper limb physical condition of the subjects participating in this study, showing differences in usability. As a result of the study, the ReVive program recorded a high average score of 81.7 points in the SUS, and the overall satisfaction was 86%. In particular, the practicality and interest factors of the program were evaluated as 4.5 points and 4.6 points, respectively, confirming that the user experience was positive. This study objectively demonstrated the effectiveness of a stroke rehabilitation program using VR technology and suggested the possibility of it as a digital rehabilitation training tool for the social reintegration of stroke rehabilitation patients after treatment.
