Three and half years ago when Nintendo released its console, Nintendo Wii, which use Wiimote as controller, (a unique controller which detects movements in three dimensions), nobody thought it will be a trend for the following years.
But now, after they become a market leader, shattered sales records, they proof that motion controller is a creative idea. Both its rivals, Sony and Microsoft try to follow their success by released a motion controller too, Sony with PlayStation Move and Microsoft with Project Natal.
Sony's PlayStation Move
Sony uses a spherical light which is tracked by the camera in concert with internal sensors, plans to charge $100 for a package including Move, the PlayStation Eye Camera and one game. They claimed that PlayStation Move is more accurate than Wii remote, so it isn't just to play a casual games, but difficult games also.
Supported Games
Tiger Woods PGA Tour 11, Ape Escape and Echochrome 2 plus old games LittleBigPlanet, Flower and Resident Evil 5.
Future Planned Games, specifically made for the controller
High-def sports suite Sports Champions, boxing game Dukes, Kung Fu game Slider, family party game Move Party and shooter The Shoot.
Microsoft's Project Natal
Just like Sony, Microsoft's project Natal for Xbox 360, uses a camera to track the movements, 3D Camera Technology for exactly, but without a controller.
Project Natal will detect the movements of the whole player's body not just the controller in the hands, so the player can play the games that's not just using hands movements but the whole body also.
