The program recognizes the movements of a person's head, allowing a cursor to move to where this man's nose is pointing. People who cannot move their necks can use their tongues, while the blink of an eye activates the double click function. And just like that, Internet sites pop up on the screen.

This is made possible by a new computer program developed by a group of students at Hansei University in Korea. "The technology works by distinguishing the characteristics of a face and tongue among the visual images picked up by a web camera." Anyone with a cheap web cam can use the program.

That's because, the students say, many disabled people in Korea may not be able to afford it if it was too expensive. "We wanted to let disabled people use computers more easily than by having to manipulate sticks or other tools."

The students are fine-tuning the program to react more sensitively to movements. And soon they plan to distribute it for free to disabled people.
