# Custom devices
|
|
|
|
Extend the Input System with devices and input sources that Unity does not provide out of the box.
|
|
|
|
Send low-level input events into the runtime, or implement a custom Device with layouts, state, and registration. Use **Input events** when you need to inject or observe raw input; follow **Create a custom device** when you integrate a third-party API or replace HID fallback behavior.
