How the device can respond to your voice and gestures.
The Microsoft Kinect is the first consumer product that lets people control an interface using gesture and voice alone. An add-on for Microsoft’s Xbox 360 video-game console, the sensor-packed device can determine your position and interpret vocal commands, all without requiring you to hold any special controllers or wear special clothing. At $150 retail, it is a relatively inexpensive way to try a next-generation interface. You might, for example, play Dance Central, a movement game made by Harmonix that teaches dance moves, watches how well you perform them, and tracks how many calories you burn during a play session.
