ok so here is my idea:
this is how it works there is screen on the floor( presumably it is projected ) and there are say three lanes on which objects can move lets just say for the purposes of explanation that they are balls, so there is a person on ether side of the rectangle and they can send a ball down one of the three lanes if the ball moves unhindered and reaches the other end you get a point if it is stopped mid way by your opponents ball no score is tallied however the length of time you stand in a lane determines how fast the ball moves if your ball is moving faster than the on coming ball it continues and vice versa... the way i was thinking this could work is with the lanes corresponding to a button of some kind say a mouse or a wii fit board... if this doesn't make sense please ask!
