项目摘要

The purpose of this research is to investigate the development of a new man-machine interface, which we call an eye mouse, that uses an automatic eye-tracking of the user of a computer.Firstly we have developed an interface system which connects the eye-tracking system with the computer. The digital signal from the eye-tracking system that is composed of the motion and the distance of eye movements toward the horizontal and vertical directions is transferred to the computer. Then, the signal is processed in order to superimpose the movements of the eye as the movements of the cursor on the computer display. It took long time to develop a software that handle the signal because we have scarcely no references. We have successfully achieved to control the movements of the cursor on monitor that is synchronized with the movements of the eye of the user.We have recognized the impirtance of the calibration and the effect of shifting the head of the subject through the experiments. At the beginning of the experiment, the calibration has to be made that controls the gain of the signal from the eye-tracking system in order to fit the extent of the eye-movements into the area of the cursor-movements on the monitor. Since the head-shift of the subject produces the shift of the position of the cursor, the area the cursor can move will deviate from the standard position on the monitor. As a result, the whole system is strongly affected by the head-shift of the subject. The problem of head-shift is relieved to a certain extent by using the apparatus that fixes the chin of the subject. However, it was shown that we have found another solution to overcome the above problem.

本研究的目的是研究一种新的人机界面的开发，我们称之为眼鼠标，它使用计算机用户的自动眼动追踪。首先，我们开发了一个连接眼动追踪系统和计算机的接口系统。眼动追踪系统将眼球在水平方向和垂直方向上的运动和距离组成的数字信号传递给计算机。然后，对信号进行处理，以便将眼睛的运动叠加为计算机显示器上光标的运动。由于我们几乎没有参考资料，开发处理信号的软件花了很长时间。我们已经成功地实现了控制显示器上光标的运动与用户眼睛的运动同步。通过实验，我们认识到校准的重要性和受试者头部移动的影响。在实验开始时，必须对眼球追踪系统的信号增益进行校准，以使眼球运动的范围与显示器上光标运动的范围相匹配。由于受试者的头部移动会产生光标位置的移动，因此光标可以移动的区域将偏离显示器上的标准位置。因此，整个系统受到主体头部移动的强烈影响。通过使用固定受试者下巴的装置，头部移位的问题在一定程度上得到了缓解。然而，事实证明我们已经找到了另一种解决上述问题的方法。
