Three-axis microelectromechanical system (MEMS)-based gyroscopes such as this one from Invensense are one step beyond the accelerometers found today in the iPhone, the PS3 and Wii. By invoking the Coriolis effect to track angular momentum, they have real-time awareness of their 3D orientation thereby allowing extremely accurate detection of human gestures. Next year I expect to see them added to GPS navigation systems for "dead reckoning" when a signal is lost indoors. Innovation in other mobile 3D chipsets, gaming accessories and software will drive usage in Remotes and useful in-air mice devices. With these small chips in wristbands, we could point like Sylar in Heroes to change HD channels or handwrite Tweets over the air.
