The D-pad (short for directional pad) is a compact input method developed for video games, designed to translate thumb movement into directional control through a flat, cross-shaped surface that rests on four internal switches. Each switch corresponds to a cardinal direction (up, down, left, and right), while diagonal inputs engage two switches simultaneously, enabling eight-directional control at 45-degree intervals.
