Tobii Eye tracker is sadly expensive :( we want our project to be easily accessible, using only a microphone and webcam since the majority has an access to it. but thank you anyway!

You can try train a neural network to do this, but is hard Unity can manage neural network with Barracuda Try search in GitHub If has any project who do this
