Microsoft showed off its Project Natal motion tracking for the Xbox 360 yesterday, and Sony just unveiled a new motion tracking PlayStation 3 controller that offers "true 1:1 tracking" and "true 3D pointing". The device is named PlayStation Motion Controller, it will be out in Spring 2010 but pricing is still unknown.
By moving the wand-like controller and its glowing top forward, back, left and right, the demonstrator was able to walk around a room in first-person, aim, and shoot. Another demonstration showed the precision of the device with handwriting and painting.
There's an analog trigger on the controller as well, demonstrated with a spray paint application. Yet another demonstration saw the player dual wielding two controllers to control a shield and sword, with each offering 1:1 motion.
