Creating a game using only the Eye Gaze data

[George Cremen-Merrill]

Hi everyone, Im fairly new to using the eye tracker in Unity and also pretty new to game development itself since I’m in my third year of Uni and for my dissertation am attempting to make a game / multiple small games using only an eye tracker. Could anyone help me with using getting the eye gaze data to simply act as a mouse input would in Unity?

Hi @ninjapandaz

Eye tracker is not really meant to be a mouse replacement unless we are talking about a fully hands-free assistive use case.

But you can use Tobii Unity SDK to get the gaze data and then raycast it into the scene:

For some 2D games (for example, card games), it might be a good idea to use Interaction Library instead of the Unity SDK:

Thanks for the reply, I’m planning on making a sort of house of the dead type on rails shooter than allows the player to aim and shoot using just their eyes, do you think this is possible with getting the gaze data and raycasting it onto the scene?
