New System that Inputs text not by finger but by using eyes

Professor Arai Kohei of Saga University’s Faculty of Science and Engineering has developed a system whereby PC users can input text simply by looking at an on-screen keyboard. When the user gazes at a character for one second, the system, which uses a miniature camera, detects their line of sight and inputs the appropriate character. The system is called Mitsumeru Dake in Japanese, which means “Just Look.” Professor Arai expects that the system will be useful to people with disabilities and for a range of medical and social-welfare applications. At present many people with disabilities are unable to use personal computers unless they have expensive special equipment.

The Professor Arai’s system basically uses user’s line of sight. A miniature camera attached to the computer notes the positions of three points for each eye: the inner corner of the eye, the inner extremity of the eyebrow, and the center of the pupil. On the basis of these six positions the system determines the direction in which the face is turned, and by following the line of sight it recognizes the exact location on the screen that the user is looking at and even people wearing glasses can use the system.

This is not the only system that uses eye movement to interact with the digital word, there are more tech out there, but the problem is its high cost. That means person who are bedridden or those who are with impaired use of hand needs to have a big amount of money for them to use PC which is really expensive and cumbersome. With Professor AKai’s system the cost is only $25 with software free of charge. This is indeed another technology that will benefit our elderly and disabled people.
