This document summarizes the history and evolution of video game controllers, specifically gamepads and direction pads (d-pads). It traces the origins of d-pads to 1980 when Gunpei Yokoi at Nintendo developed the first d-pad for a handheld game device. It describes how d-pad designs evolved over time as new game systems were developed, changing shapes from simple crosses to more complex geometric shapes. The document explores hypotheses for why gamepads remained prominent inputs even as motion controls emerged and presents diagrams mapping the evolution and adaptations of d-pad shapes across different controllers over time.
