Abstract:
Objective:To compare the effectiveness of a new virtual reality (VR) working memory test system with that of the traditional E-prime working memory test system in terms of evaluating executive function in cognitive rehabilitation.Methods:Two experienced rehabilitation therapists tested 30 healthy subjects. The average reaction time and accuracy of the traditional and the VR-based working memory test systems in completing the 2-back task were compared. The usability and user experience of the VR-based working memory test system were also evaluated using the system usability scale (SUS), a simulator discomfort scale (SSQ) and semi-structured interviews.Results:There was no significant difference in the average reaction time and accuracy of the 30 subjects between the two different tests. The SUS score of the VR working memory test was at the " Good-Excellent" level, and the SSQ scores demonstrated that no significant discomfort was observed. In the interviews the VR working memory test system was described as easy to operate and as having a strong sense of immersion.Conclusions:The VR-based working memory test system has good usability and user acceptance, and can provide subjects with an immersive and persona-lized test scenario. Therefore, it can be used as a tool for testing working memory.
