Bright Side of News found a demonstration of Razer's Hydra, a motion controller based on the Sixense technology, with The Elder Scrolls V: Skyrim. Looks pretty sweet.
If you ever played Nintendo Wii, the Sixense controller operates at a similar concept of motion. However, similarities end there. At the end of the day, Nintendo is a console controller and applications are adjusted as such. Sixense technology is optimized for PC gaming, which has much more controls and the way of thinking is different.
