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

为了制定虚拟现实环境中使用的 3D 显示器的设计指南，我们对 100 多名年龄在 17 至 27 岁之间的受试者进行了调查，了解头显和 3D 显示器 (3DD) 对人体的影响。使用与视觉、自主和平衡功能相对应的生理参数在本报告中评估了通过 HMD 和不戴眼镜的 3DD 观看视频电影对动态调节的影响。根据心率波动的频谱模式估算视觉反应和交感-副交感神经活动。根据我们的研究，我们现在能够为 HMD 和 3DD 的设计提出指导方针，不会对人体造成任何有害影响。基于从调节的阶跃响应中获得的最可靠的结果^*，本指南的 2 个原则如下：1) 对于设计师而言，我们指南的原则是 HMD 和如果观看 30 分钟图像后 90 分钟动态调节的斜率明显较小，则不应设计 3D 显示器（包括其内容）。2）对于用户而言，头显的使用时间不应超过 4没有 90 分钟休息的情况下使用 2 小时或没有 60 分钟休息的情况下使用 2 小时 其次，在没有 90 分钟休息或 15 分钟的情况下，裸眼 3D 显示器的使用时间不得超过 30 分钟；没有60分钟的休息。^*调节的阶跃响应意味着调节眼睛晶状体所需的速度。通过测量速度，可以估计视觉疲劳和副交感神经活动。需要在下面进行更多的实验。此外，在得出有关这种机制的结论之前，有必要研究这种视觉装置对老年人、年轻人以及患有视觉或自主神经疾病的人的各种影响。两者的设计均已达到研究目的不会对人体造成任何有害影响的 HMD 和 3DD。
