1) The development of the head mounted eye movement measurement device : The device that both eyes' movements could be measured was developed to make the fatigue problem on the virtual reality environment clear. This device was attatched on the head mounted display. Both eyes' movements can be measured with this device when an actual space environment, a virtual reality environment, and a compound reality environment are being observed. In this device the measurement of fixation point was based on the center location of the pupil by the video image. Two kinds of algorithm were developed about the central location of measuring it of the pupil. The method of Haslwanter (1995) was used for the way of calculating an eye position from the pupil center position. And we developed a new calibration method to improve space accuracy.2) Experiments : The eye movements on the actual space observation and the stereoscopic image observation were measured and compared. Regardless of the actual space observation and the stereoscopic image observation, the results showed that non-dominant eye did not point to the object in some cases. The object was moved to the right and left of the horizontal, there were few differences between both observations. However, it was moved to the front and back, there were a larger differences. The convergence - divergence movement did not found in the stereoscopic image observation. This result can be interpreted that observer did not use ample depth cues on the stereoscopic image observation and this causes the fatigue on the virtual reality.

1）头部安装的眼动测量装置的开发：可以测量两种眼睛运动的装置，以使虚拟现实环境上的疲劳问题清除。该设备已在头部安装显示屏上进行。当观察到实际的空间环境，虚拟现实环境和复合现实环境时，可以用该设备测量两只眼睛的动作。在此设备中，固定点的测量基于视频图像的学生中心位置。开发了两种算法，涉及测量学生的中心位置。 Haslwanter（1995）的方法用于从学生中心位置计算眼睛位置的方式。 2）实验：测量并比较了实际空间观察和立体图像观察的眼睛运动。不管实际的空间观察和立体图像观察如何，结果表明，在某些情况下，非主导的眼睛并没有指向该物体。物体被移至水平的右侧和左侧，两个观察结果之间几乎没有差异。但是，它被移至前后，差异更大。在立体图像观察中未发现收敛性 - 差异运动。可以解释一下，观察者没有在立体图像观察上使用足够的深度线索，这会导致虚拟现实的疲劳。
