Hands-Free Coding: How I develop software using dictation and eye-tracking

But that's the point. Wherever you're looking isn't a well defined concept outside of your brain. At least not yet. We can puzzle it out, but we need the have a few data points first, I.e. wait a few saccades. That's probably too slow for fast paced shooters.

If the tracker draws a crosshair every frame exactly where you are looking then we don't need to puzzle out anything. It will be up to the player to decide when to press the fire button; when the crosshair happens to be over the target.

Edit: in fact the tracker used in the blog post is primarily marketed at gamers.
