Eye tracking software

Question

I am looking for an application that uses a computer camera to track eye movements and works like a pointing device. Something open source maybe?

It doesn't have to be very accurate.

EDIT: OS: Windows XP

Answer 1

Some are windows some aren't. i think they all require some sort of ir camera pointed at the eye though. head tracking might work better for you if you don't want to build hardware as head tracking software usually only needs a white dot or something obviously contrasted on the forehead.

Answer 2

OpenGazer is one such ( http://sourceforge.net/projects/opengazer/ ) - there are no binaries available, however just the sources.

Answer 3

Once I used a software called Visual Mouse for that. It works by using body parts (like fingers) with dots, but I could also successfully use it with my eye.

The only downside is that it required a lot of lighting, so I had to use a direct light source on the eye, which obviously caused a lot of eyestrain. In this case an IR camera/lighting system would be better.
