What Does Gesture Recognition Mean?

Gesture recognition refers to the mathematical interpretation of human motions using a computing device. It is a component of perceptual user interface (PUI). Other popular PUI components are voice recognition, facial recognition, lip movement recognition and eye tracking. Gestures could possibly come from any state or bodily motion; however, they usually originate from the hands or face. At present, gesture recognition is mainly centered on hand-gesture recognition and facial emotion recognition.

Techopedia Explains Gesture Recognition

Gesture recognition helps computers to understand human body language. This helps to build a more potent link between humans and machines, rather than just the basic text user interfaces or graphical user interfaces (GUIs). These old-fashioned input methods still limit most inputs to mouse and keyboard.
