It seems that it can only handle Discrete Data, in that it has a yes or no choice, which is why he is having to use the mouse to contol the FOV. However, i don't understand how it would differentiate which control would be triggered by what, I'm fairly sure that when I play games, it's the same part of my brain functioning, and whether I want to jump or cahnge weapon, it's a similar sort of action going on in my head, the only difference being in my co-ordiantion, as such my nerves. How that would all be picked up by a head band, I have no idea.
