A woman sits at a desk in front of a computer webcam, demonstrating hand gestures to control virtual lights. The interface shows the title “Gesture control with live gestures,” explaining how gestures can be used to control lights via AI. Two lightbulb icons appear on either side of the frame, and a button labeled “Predict” is visible below the video feed.
