Sorry but what you're saying simply is not true from my experience. The potential of this technology is the ability to perform multiple actions simultaneously e.g. having your character strafe while zooming in while firing a trigger. With eye tracking you are limited to (for the most part) one action at a time, which is what I do now.

You are correct in that one could add more inputs but that only works if you can use the inputs. The individual in the video has full control of his head which many people do not. All I can do, for example, is use like two fingers.
