gesture recognition
Reading body movements
Gesture recognition is technology that interprets human movements—hand waves, finger points, body positions—as input commands.
Cameras or sensors track motion and translate it into instructions for devices: swiping to change slides, waving to answer a video call, or raising a palm to pause playback.
The technology appears in gaming systems, smartphones, and accessibility tools.
