Nintendo’s Wii made using physical gestures to interact with cutting-edge video games a global phenomenon. Motion gaming lets players steer vehicles or swing swords just by mimicking real-life movements. New innovations in motion gaming, including Sony’s wand-based PlayStation Move and Microsoft’s Kinect, are broadening the appeal of active gaming. But motion-gaming technology on consoles and PCs actually dates back decades -- and the same core challenges that developers faced 20 years ago in the NES Power Glove era are still present today. Developers are trying to determine how to not just create great games with motion controls, but also build games designed to support a growing range of 3D movement.
