基于眼睛的人机交互的移动键盘：HCI是为残疾人和老年人特别提出的。提出的移动键盘将克服当前基于眼睛的人机交互存在的问题：(1)输入成功率差，(2)输入速度慢。键盘的移动是通过用户盯着其中一个位于键盘中央和上下左右两侧的放大半透明键来实现的。选中的键总是显示在显示中心。因此，选择的键很容易找到，可以通过眨眼或将眼睛固定在键上一秒钟来确定。实验结果表明：(1)注视位置的可变性，(2)按键大小，(3)按键个数，(4)相机分辨率与按键成功率之间的关系证明了该方法的有效性。详细介绍了建议的系统，然后进行了绩效评估，以克服上述问题。
< Summary> Moving keyboard for eye-based Human-Computer Interaction: HCI is proposed for disabled and elderly persons, in particular. The current problems on eye-based HCI,(1) poor key-in success rate, and (2) slow key-in speed are to be overcome with the proposed moving keyboard. The keyboard is moved by the gaze of user looking at one of the enlarged semi-transparent keys located at the center and surrounding up/down/right/left hand sides. Selected key is always shown at the display center. Thus the selected key is easy to find and can be determined by blinking or by fixing one's eye on the key for a second. Experimental results of relations between key-in success rate and (1) variability of gaze location,(2) key size,(3) the number of keys,(4) camera resolution are introduced which show the validity of the proposed method. The detailed proposed system is described followed by performance evaluations to overcome the aforementioned problems.
