基于虚拟现实技术的心理健康状况测评系统

Mental health evaluation system based on virtual reality technology

传统测评系统难以构建出虚拟的测试环境,导致心理健康状况测评效果较差,因此设计基于虚拟现实技术的心理健康状况测评系统。该系统利用传感器、数据手套、头盔显示器等硬件设备采集测评人员心理健康数据;利用图像模块、交互控制等模块结合VC++和OpenGL构建虚拟现实心理健康评测环境,以提高测评有效性。使用层次分析法构建测评模型,完成心理健康状况测评。实验结果表明:该系统生态效度接近100%,且测评人员的空间存在感、参与感百分比均超过95%,虚拟现实模拟效果较好。

The traditional evaluation system is difficult to build a virtual test environment,which leads to the poor effect of mental health evaluation.Therefore,a mental health evaluation system based on virtual reality technology is designed.The system uses sensors,data gloves,helmet-mounted display and other hardware equipment to collect the mental health data of evaluation personnel.Meanwhile,the virtual reality mental health evaluation environment is constructed by using image module,interactive control module,VC++and OpenGL to improve the effectiveness of the evaluation.The analytic hierarchy process is used to construct the evaluation model and complete the evaluation of mental health.The experiment results show that the ecological validity of the system is close to 100%,and the percentages of spatial presence and participation of the evaluators are more than 95%,showing the good effect of the virtual reality simulation.
