我们一直在开发一个打字训练系统，我们试图支持触摸打字训练，其中必须检测眼睛注视，以检查受训者是否在看键盘。眼睛注视检测功能被设计为使用具有内置或通用USB摄像头的普通PC，并且至少实时区分受训者是在看显示器还是键盘。提出了一种简单、快速的两阶段判别法。第一阶段是通过模板匹配检测眼睛区域，第二阶段是通过形状匹配识别眼睛注视。在短时间的校准后，使受训者自己的模板图像和确定形状匹配的阈值，眼睛注视被成功地检测到每秒超过15次。
We have been developing a typing training system and we tried to support touch-typing training, where eye-gaze must be detected for checking the trainee is not looking at the keyboard. The eye-gaze detecting function was designed to use a normal PC with a built-in or general USB camera and to discriminate at least whether the trainee is looking at the display or the keyboard in real-time. We developed simple and quick discriminating method consisting two stages. The first stage is detecting eye regions by template matching, and the second stage is discriminating eye-gaze by shape matching. After a short-time calibration for making the trainee's own template image and determining the threshold for shape matching, the eye-gaze is successfully detected more than 15 times per a second.
