Thanks for thinking along.

What I was thinking of, in a game setting, to use the phone as some sort of hack & slash device. Given my opponent and me are withing reasonable proximity, she with -say- a spear-device, me with a sword or so. She could try stabbing me, while I parry. The devices have to calculate the hit ratio.

Would a sound-code offer a possible solution? Could we measure some doppler effect with the built in microphone?

And, on a side note... How impact proof will the phone be, might she try throwing her spear? :-P
