Gesture Recognition is a topic in computer science with goal of interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion or state but commonly originate from the face or hand. Current problems in the field include emotion recognition from the face and hand gesture recognition.

Using 2 video stereo cameras together with a postioning reference such as a lexian-stripe or infrared emitters enables humans to interface with the machine (HMI) and interact naturally without any mechanical devices. It is possible to point a finger at the computer screen (or any other screen) and the cursor will move accordingly on the screen. This could potentially make conventional input devices such as mouse, keyboards and even touch-screens redundant. Such motion interactive media (MIM) is beginning to pave it's way into commercial applications.

Gesture recognition is conducted with techniques from computer vision and image processing.
