Development of eye-gaze interface for daily use

在本研究中，开发了一种使用单个相机来估计注视点的方法，该方法既不依赖于用户也不依赖于环境参数。接下来，开发了一种点击界面，用户可以通过目光移动来移动光标，并通过随意眨眼或短暂注视来点击计算机鼠标。平均而言，在眨眼、短暂注视和正常手部操作的情况下，指向并点击一个目标的时间分别为 1.2 秒、0.9 秒和 0.8 秒。

In this study, a method for the estimation of point of gaze with neither user- nor environment-dependent parameters using a single camera was developed. Next, a point-and-click interface, in which a user can move a cursor by a gaze shift and click a computer mouse by a voluntary eye blink or short fixation, was developed. On average, it took 1.2, 0.9, and 0.8 sec to point and click for one target with eye blink, short fixation, and normal hand manipulation, respectively.
