Implementation of Enhanced Virtual Mall for Measuring Executive Functions

Abstract

Objective: This study aims to measure working memory and decision-making ability in the enhanced virtual mall environment based on the embodied cognition theory. Background: Various technologies have been emerged to allow more precise measurements of patients' behavioral data. Therefore, we have developed the Virtual Mall environments based on the embodied cognition theory, to provide the possibilities of evaluation indicators other than those given by the traditional neuropsychological tests in the virtual environments. Method: Based on field observation, we developed the self-checkout system to measure the executive functions, and the results of performance were categorized by MET tests. Finally, we evaluated the possible form of clinical programs based on professional comments by the HCI and medical experts. Results: Four HCI experts reviewed eight elements of usability, and five medical experts assessed the potential of this program as a clinical purpose. Conclusion: This suggests that the self-checkout system developed in this study has potential as a clinical program. Application: These results of this study will be useful as a foundational work to create the VR scenarios and VR environment in neuropsychological tests for the measurement of working memory and decision making.
