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.

这项研究的目的是调查我们称为Eye Mouse的新型Man-Machine界面的开发，该接口使用了计算机用户的自动眼球跟踪。首先，我们开发了一个将眼睛跟踪系统与计算机连接的接口系统。来自眼睛跟踪系统的数字信号由运动组成，眼动向水平方向和垂直方向的距离转移到计算机上。然后，处理信号以将眼睛的移动叠加为光标在计算机显示屏上的运动。由于我们几乎没有参考文献，因此花了很长时间才能开发出处理信号的软件。我们已经成功地控制了光标在监视器上的运动，该移动与用户眼睛的移动同步。我们已经认识到校准的影响力以及通过实验将受试者转移的效果。在实验开始时，必须进行校准，以控制眼睛追踪系统的信号增益，以便将眼动的范围拟合到监视器上光标移动区域。由于该受试者的头部班次会产生光标位置的偏移，因此光标可以移动的区域将偏离监视器上的标准位置。结果，整个系统受到主题的前提的强烈影响。通过使用固定受试者下巴的设备，可以在一定程度上解释头班的问题。但是，证明我们找到了另一个解决方案来克服上述问题。
