"Nintendo's Wii gaming system motivates first-graders, senior citizens and everyone in between to get off their couches and play video games by swinging a motion-sensing remote control. These motions are similar enough to those used in real-life games that people find the Wii less intimidating than other video games with confusing controls.
After almost three years of Wii success, Nintendo recently reported it sold in its first quarter less than half the Wii consoles it sold a year earlier. The Wii needs a shot in the arm, and Nintendo thinks it has just the solution: the Wii MotionPlus remote accessory."
