A D-pad is a flat, typically thumb-operated, directional control. D-pads are found on nearly all modern gamepads, handheld game consoles, and audiovisual device remote controls. Because they operate using four internal push-buttons, the vast majority of D-pads provide discrete, rather than continuous, directional options—typically limited to up, down, left, and right, and sometimes offering intermediate diagonals by means of two-button combinations.

A handheld game console, or simply handheld console, is a small, portable self-contained video game console with a built-in screen, game controls and speakers. Handheld game consoles are smaller than home video game consoles and contain the console, screen, speakers, and controls in one unit, allowing players to carry them and play them at any time or place.
