Microsoft Kinect is a motion-sensing input device developed by Microsoft for the Xbox 360 and later for Windows. It allows users to interact with games and applications using body movements and voice commands, eliminating the need for traditional controllers. The device uses a camera, depth sensor, and microphone to track movements and recognize spoken commands. Launched in 2010, Kinect was designed to enhance gaming experiences by providing a more immersive way to play. It gained popularity for fitness games and family-friendly activities, and its technology has since influenced various applications in fields like healthcare and education.
