D-Pad
The D-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, while diagonal inputs engage two switches simultaneously, enabling eight-directional control at 45-degree intervals. Beneath the center, a pivot mechanism tilts the pad, preventing all four switches from being pressed at once and enhancing tactile feedback.
