# How input works

<!--{"order": 900, "parent": "input"}-->

**One interface, many devices.** Every source (keyboard and mouse, a hardware
pad, touch, VR controllers, an AI) produces the same `ControlInput`, and every
drivable thing consumes it. These pages are the layers: the interface, the
virtual gamepad that sources fill in, and one page per device.
