The NerveGear made various calculations and measurements during the calibration. There'd have to be a lot of math going into that, and it'd have to be very accurate. Powerful sensors today can already do what the NerveGear did.

"Transmitting it to the game" is the easy part, considering all the NerveGear has to do is package the information and send it as a file. The NerveGear clearly SAVES the data to its local storage for reuse later (otherwise, you'd be recalibrating the thing every time) The game just has to ask for your info, and it's sent.

I'm actually baffled that your question is "how does the game get it?", and not, "How does the NerveGear measure it?"
