GestureTek Windows Mobile Client Will Motion and Object Traking.

"GestureTek will announce at the Consumer Electronics Show (CES) that its patented, award-winning software for gesture-based mobile device interaction now supports the Android® operating system. The company is also launching a brand new engine that allows Windows® Mobile publishers and developers to integrate motion and object tracking into their gesture-control games and applications."

Controlling by motion may be an acceptable solution with the lack of buttons and D-pads on modern devices. It will be interesting to see how GestureTek's product is used by devlopers!
