Computerized Screening and Testing System for Elderly Cognitive Health Based on Virtual Reality

Introduction: This paper aims to design a test system for elderly patients with cognitive impairment through VR technology to optimize the allocation of medical resources and improve the effect of cognitive testing. A VR cognitive system with functions such as user registration and login, VR task testing, and operation learning modules was designed, and it was developed under the principles of scientificity, interactivity, and convenience. Method: The study went through steps such as system construction, user experience testing, cognitive load assessment, task completion, and system stability verification. Result: The results showed that the system received high evaluations regarding user experience, task completion, and system stability, but cognitive load still needed to be optimized. The experimental comparison also found that the VR cognitive test system had a cognitive recovery degree of 30% to 60% for the elderly, while the traditional system was 10% to 25%. Conclusion: From these data, it can be seen that the VR elderly cognitive test system does contribute to the cognitive health of the elderly.
