项目摘要

In order to formulate a guideline for the design of 3D-displays used in a virtual reality environment, we have been investigating how HMDs and 3D-displays(3DDs)affect the human body for more than 100 subjects aged from 17 to 27 years old by using physiological parameters corresponding to the visual, autonomic and equilibrium functions. In this report, an evaluation has been made of the effects of viewing video movies through an HMD and a 3DD without glasses on a dynamic accommodation response of vision and sympathetic-parasympathetic nerve activity estimated from spectral patterns of heart rate fluctuations.From our research, we are now able to propose guidelines for the design of both HMDs and 3DDs that will not result in any harmful effects on the human body. Based on the most reliable findings obtained from the step response of accommodation^*, the 2 principals of this guideline are as follows :1)For designers, the principle of our guideline is that the HMDs and 3D-displays(includin … More g their contents)should not be designed if the slope of the dynamic accommodation is significantly small 90 minutes after viewing 30 minutes of images.2)For the users, the HMD should not be used for more than 4 hours without a 90 minutes rest or 2 hours without a 60 minute rest ; secondly, the glass-free 3D-display should not be used for more than 30 minutes without a 90 minute rest or 15 minutes without a 60 minutes rest.^*The step response of accommodation means a velocity needed to adjust an eye lens. By measuring the velocity, both the visual fatigue and the parasympathetic nerve activity can be estimated.Many more experiments need to be carried out under various conditions before drawing any conclusions regarding such mechanisms. Furthermore, it will be necessary to investigate the various effects of such visual apparatus on the elderly, the young and on people with visual or autonomic disorders. Although there are some problems to be solved, our research purpose has been accomplished for the design of both HMDs and 3DDs that will not result in any harmful effects on the human body. Less

为了构成虚拟现实环境中使用的3D播放的指南，我们一直在研究HMD和3D-播放（3DDS）如何通过使用与视觉，自主和平衡功能相对应的物理参数来影响17岁以上17岁以上的受试者的人体。在本报告中，已经对通过HMD和3DD观看视频电影的影响进行了评估，这对视力和交感神经 - 交感神经的神经活动的动态适应性响应是根据心率波动的波动估计的。从我们的研究中，我们现在可以对HMD和3DD的设计指南，从而对人类的设计进行任何损害。基于从适应性的步骤响应^*获得的最可靠的发现，本指南的2个主体如下：1）对于设计师，我们的指南的原理是，HMDS和3D diSplays（包括更多的内容）不应在动态的斜坡上更加小时，而不是在观看30分钟后不使用30分钟的30分钟图像，而不是更多地设计。休息90分钟或2小时，没有60分钟的休息；其次，无玻璃3D播放不应在没有90分钟的休息或15分钟的情况下使用超过30分钟，而无需休息60分钟。通过测量速度，可以估算视觉疲劳和副交感神经活动。此外，有必要研究这种视觉仪器对老年人，年轻人以及视觉或自主性疾病的人的各种影响。尽管有一些问题要解决，但我们的研究目的是针对HMD和3DD的设计实现的，这不会对人体产生任何有害影响。较少的
