Q: Why is PlayStation Move better than the Kinect or the Wii?
A: PlayStation Move is the most powerful, precise, and easy-to-use motion controller ever designed. It combines the strengths of a physical controller — physical buttons and vibration feedback — with the flexibility afforded by motion controls as well as unmatched precision. PlayStation Move can also precisely detect the absolute position of the controller held by the users in real-life 3D space. Additionally, it makes use of the PlayStation Eye camera for head and body tracking, photo and video capability, online video chat and more.
Combined with the unmatched power and HD capabilities of the PS3 system, PlayStation Move enables the most robust and sophisticated motion gaming experience.
