摘要： 提出一种新的基于视线跟踪和手势识别的交互方式用于远距离操作计算机。系统通过摄像头采集用户的图像，利用图像识别算法检测人眼和手指的位置，由人眼和指尖的连线确定用户指向屏幕的位置，通过判别用户手势的变化实现各种操作，达到人机交互的目的。实验结果表明，该交互方式可以较好地定位屏幕和判断用户的操作，实现自然、友好的远距离人机交互。

Abstract: This paper presents a novel human-computer interaction for long-distance operation based on gaze tracking and gesture recognition. The system analyzes the image captured by camera and finds the position of eyes and fingers through some recognition algorithms. The position which user points to the screen finds through the line from the eye to the finger. By recognizing user’s gestures, the system executes various operations. Experimental results demonstrate that the interaction can locate the position on the screen and recognize user’s gesture. This method achieves friendly and natural long-distance human-computer interaction.

Key words: human-computer interaction, gaze tracking, gesture recognition
