项目摘要

In recent Virtual Reality (VR) systems, various practical applications have been expected in many fields such as medicine, rehabilitation and education. Therefore, enough considerationn of human factors are needed to construct the safe and comfortable VR systems. However, there is seldom a VR system that sufficiently considered the human factors actually. A guideline for the safe VR systems to prevent human from undesirable reactions such as motion sickness is desired. So we carried out a research project how to prevent or reduce VR sickness in virtual environments. First, we developed an integrated VR stimulation system that could control and display visual, acoustic and vestibular stimuli simultaneously, and then a monitoring system of human body reactions. Secondly, using these systems, we examined whether visually induced self-motion perception (vection) that was possible to relate the VR sickness could control or not by a different kind of sensory stimulation such as an acoustic or vestibular stimulus. From our experimental results, it was ascertained that the acoustic and vestibular stimulus was effective to reduce the vection. In addition, we examined influence on human body concerning temporal and spatial gaps between a real and a virtual word under Mixed Reality using a video see-through MHD. From our experimental results, it was ascertained that manipulation efficiency in using a 3D-HMD was better than a 2D-HMD although the efficiency strongly depended on time delay. Side results except the above-mentioned studies were 1) influence on human visual system by using a HMD for a long time, 2) effects of optokinetic stimulations produced from a wide view HMD on standing balance, 3) effects of a fixation target on torsional optokinetic nystagmus, 4) visual system associated with falls in the elderly, and 5) development of a hearing aid system using both a see-through HMD and an automatic speech recognition system.

在最近的虚拟现实(VR)系统中，在医学、康复和教育等许多领域都有望得到各种实际应用。因此，构建安全舒适的虚拟现实系统需要充分考虑人的因素。然而，真正能充分考虑人的因素的虚拟现实系统却很少。一个安全的VR系统的指南，以防止人类的不良反应，如晕车是必要的。因此，我们开展了如何预防或减少虚拟环境中的VR疾病的研究项目。首先，我们开发了一个可以同时控制和显示视觉、声音和前庭刺激的集成VR刺激系统，然后开发了一个人体反应监测系统。其次，使用这些系统，我们研究了可能与VR疾病相关的视觉诱导的自我运动知觉(Vect)是否可以通过不同类型的感觉刺激(如声音刺激或前庭刺激)来控制。从实验结果可以看出，声学刺激和前庭刺激能有效地减少视动。此外，我们使用视频透视式磁流体研究了混合现实中真实世界和虚拟世界之间的时空差距对人体的影响。从我们的实验结果可以确定，使用3D-HMD的操作效率比使用2D-HMD要好，尽管其效率强烈地依赖于时间延迟。除上述研究外，其他研究结果包括：1)长期使用头盔对人类视觉系统的影响，2)广角头盔产生的视动刺激对站立平衡的影响，3)注视靶对扭转视动性眼球震颤的影响，4)与老年人跌倒相关的视觉系统，5)研制出同时使用透视式头盔和自动语音识别系统的助听器系统。
