cursor movement through eye

I was thinking whether it could be possible to track cursor movement through eye. Depending on which part of screen , the eye looks the curson will move. Can this be achieved? Thansks everyone for replying!.I am just looking for some new idea that can be implemented and which have not been implemented.Any id开发者_运维百科eas/suggetions are welcomed.

This field is called Eye Tracking. There is a great deal of work done on this, but you do need specific hardware - at the least cameras focuessed quite tightly on the subjects eye.

Cursor movement is not useful as a method of eye tracking, as far as I can tell.

This is a well known subject in Human Computer Interface.

The idea to control the pointer with your eyes won't easily work according to me (since our eyes are always distracted by external inputs). Image you're dragging a folder with your brand new eye-mouse and a nice lady walks just outside of your window :)

Anyway, eye tracking could be useful, for example, for safety applications (you could check the eyes of a bus driver are focused on a range angle - the street - and you might want to trigger a sound alarm if he's distracting/falling asleep).

You'd probably need hardware to track this, but I'm sure it's possible. A better question would be is this useful.

Think about how annoying it would be to read if the cursor kept moving along with your eyes. Even reading this text, you'd have the cursor moving along with your eyes. Personally, I would find it distracting and annoying. BUT it is an interesting challenge, and I'm sure that there would be good applications.

What are you trying to achieve? You ask a similiar question about controlling the cursor here. Maybe if you asked a clear question about what you want to achieve. Right now it looks like you are just creating questions for any which way to control the cursor.
