Acquire eye gaze direction at low cost
I'm now helping a doctor develop a device which could record eye gaze direction in a real time, we want to buy a commercialized device to realize the function, but we find most eye tracker, they r too expensive, doctor don't want to spend so much money on this.
we just want to know the gaze direction in real time and better make it a head mounted device. so we decide to develop this device based on infrared webcam, i want to know if there is a commercialized or opensource software could use the webcam picture to acquire the eye gaze direction data?
or it would be good if you have a better idea to acquire eye gaze direction at low cost.
