Over the last few years, people have seen motion controller technology take the video game industry by force. The Sony EyeToy and the Nintendo Wii have shown that game interfaces can go beyond the traditional keyboard and mouse or game controller to create more realistic, immersive, and natural gameplay mechanics.
In fact, in the next few months, with the Sony Move, Microsoft's Natal, and Sixense's TrueMotion, every major console and the PC will have input peripherals that support 3D spatial interaction. This paradigm shift in interaction technology holds great potential for game developers to create game interfaces and strategies never thought possible before. These interfaces bring players closer to the action and afford more immersive user experiences.
