Evaluation Study of Virtual reality boty within the Human Body and within Society

这份报告简要描述了虚拟现实(VR)在人体内和社会内的评估研究取得的结果。最具体的结果来自医学应用。建立了一种使用VR技术的新的手术方法，并证明了其有效性。在这种方法中，3D-MRI或CT扫描图像通过半透明镜子叠加在患者的头部，以在手术前看到疾病的部位。作为虚拟现实技术在助残领域中的一种应用，本研究探讨了人、鼠形状对音素知觉的影响，以期构建一种针对沟通障碍的训练方法。结果表明，虚拟现实技术能够有效地利用视听信息获取语言概念。通过生理和心理实验，评价了虚拟现实刺激对人体的影响。结果发现，远周视表现出的视动刺激干扰了姿势控制，导致晕动病。这种影响在宽视觉显示器的情况下比头盔显示器更大。指出VR刺激对人体影响的评价应从多方面入手，结合客观试验进行。从实验心理学的角度，定量分析了VR暴力游戏对人类后续攻击行为的影响。结果发现，暴力游戏导致了攻击性行为，且在玩游戏的情况下，攻击行为比只看游戏的情况下更大。在不久的将来，需要一项长期的社会学研究来评估虚拟现实技术对社会的影响。

This report briefly describes the results obtained from evaluation studies of virtual reality (VR) both within the human body and within society. The most concrete result was obtained from a medical application. A new surgical method using VR technology was established and its efficacy was proved. In this method, 3D-MRI or CT scan image is superimposed on the patient's head via a semi-transparent mirror to see the seat of a disease before the operation. As an application of the VR to the aid for the disabled, an influence of humans mouse shape on phoneme perception was investigated in order to construct a training method for the communication disorder. From the results, the VR was found to be useful to get language concept using audio-visual information. Influences of the virtual reality stimulation on the human body were evaluated based on physiological and psychological experiments. From the results, optokinetic stimulation displayed on far peripheral vision was found to disturb the posture control and cause motion sickness. This influence was larger in the case of a wide visual display than a HMD. It was pointed out that the influences of the VR stimulation on the human body should be evaluated based on many-sided approach and objective tests. Furthermore, the influence of the VR violent game on subsequent aggressive behavior of the human was quantitatively analyzed from a point of view of experimental psychology. From the results, it was found that the violent game causes the aggressive behavior and its behavior is larger in the case that the subjects play the games than that they just watch them. In the near future, a long-term sociology study will be necessary to evaluate how the VR technology influences on the society.
