writes with news that Microsoft has purchased 3DV Systems
, a company that specializes in motion detection technology. When early reports of this deal appeared last week, it led to speculation that this could be part of Microsoft's plans for future gaming technology
. 3DV itself has been focused on the gaming market. "Now that graphics have become so advanced, it explains, the key to making a real difference lies in how you can control the game. The ZCam lets players control the game using body gestures alone, rather as PlayStation's EyeToy does, or Microsoft's Vision or Nintendo's Wii. 3DV Systems argues that its system is better than these, adding that you don't have to wear anything."
