Cellphone to be the next game controller?

Looks like Nintendo’s yet unreleased Wii console have sparked off the imagination of some folks at the Human Interface Technology Laboratory in New Zealand who then used the idea to turn a pair of Nokia Series 60 cellphones into controllers for the AR Tennis game. Play takes place on the cellphone displays, but the virtual tennis court is the space between both players. Bluetooth technology is used to synchronize ball movement between the phones. Get the ball in play by hitting a button and swing your phones like in an ordinary tennis game after that to hit the ball over the net.
