The Design And Implementation Of Eye-Tracking System Base On Machine-Vision

With the development of Human-Computer Interaction Techniques, except the traditional mouse and keyboard, voice input method has entered practical stage. Because of the human sight includes a lot of information of current tasks, it can naturally becomes a candidate input channel. Human-Computer Interaction Techniques research about human sight is becoming more and more important.In this paper, our method is based on the Human-Computer Interaction of human sight to combine mature machine-vision and virtual instruments. We used the camera which can be easily found on the market to gather the images of human eye by untouched way and the virtual instrument which consist LabVIEW, Vision Assistant and IMAQ Vision to process and identify the gathered images. At last, we had built Human-Computer Interaction platform to accomplish eye tracking system which uses human sight to control computer mouse.This system combined machine-vision and virtual instruments to accomplish a new try of Human-Computer Interaction of human sight and computer. This is a valuable research field.
