Research Abstract

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
