It's often said that the eye is the window to the soul．But in this case, the eye is the window to Windows．At least, that was the goal when EyeTech Digital Systems got the help of some BYU engineering students in creating an all－in－one eye－tracking system．
The idea behind the project was to create an inexpensive computer system that could be controlled completely with a person's eyes．The hope was that this system could be used by people with disabilities in parts of the world where they can't afford expensive eye－tracking systems．The students created the tablet(书写板)for their yearlong engineering project for their customer, EyeTech Digital Systems, an Arizona－based company that designs and develops eye－tracking software．
A separate BYU engineering team also worked with EyeTech last year to develop and improve the initial eye－tracking tephnology, but this year's focus was to put the eye tracking into a housing similar to a thick PC．The finished product runs Windows 7 and has the eye－tracking system built in．After a quick adjustment, the system can move the mouse to wherever the user is currently looking．All it takes is a blink(眨眼)to click．
Systems with similar abilities can cost upwards of ＄14, 000．But the students were able to find cheaper, readily available parts, pushing the cost down to under ＄1, 500．Jedediah Nieveen, the captain for this year's team, said the project was a challenge, but one that was rewarding on many levels．"A lot of times in school you just work problems out of books, " he said．"But this allowed us to take what we learned and apply it to something in real life, something that can help a lot of people, and that's really helped me．"
Although the primary purpose of the product is to help people with disabilities, the technology could also have broader applications in the fields of research, advertising and even gaming．
