> The mouse is a very clever abstraction It's more like an extension of the body itself, the same way we use any tools. And there's a set relation between causes and effects, which becomes more instinctual the more we use it. I think eye tracking suffers from that we use our eyes for perception, not action. Constraining it to action, especially with how slow our movement is, will barely improve our interactions, and may impede them.
