This interaction features a circular slider used to set a camera's self-timer. As the user drags the circular handle along the track, the white progress arc dynamically draws and retracts to match the handle's position. Simultaneously, the central countdown text updates in real-time (e.g., changing from 7s to 2s, 3s, and 8s). The movement is highly responsive, mimicking a physical dial with smooth, continuous feedback.
