Answer 1

You basically can do two thing: focus on a point and switching focus.

To be able to focus on a point your brain needs to compensate many environmental factors, like the movement of your head or the movement of the object itself, the distance, the brightness, color temperature, etc.

So following an object is not that different compared to staring at a fixed object.
