New gadgets take swing at Wii
Nintendo Corp.'s Wii game console is a breakout hit in large part because users control the play by waving around a motion-sensing wireless controller.
Many new gadgets are taking the idea of such an intuitive interface several steps further. Soon, you may be able to control computers, television sets, even cell phones with hand gestures alone.
In one demonstration by 3DV Systems at the International Consumer Electronics Show here this week, users stood in front of a large screen and controlled a Windows computer with hand gestures: thumb left to go left, index finger right to go right, victory sign for Enter.
