Can any microcontroller send a signal back to a joystick?

In wireless mode, can (for example) a bump sensor send a signal back to the joystick? Do any of the microcontrollers send a wireless signal back to the operator? I don’t want to be exhaustive here, but I’m looking for a piece of hardware that could report a bump sensor operation back to a joystick (or any other device that you guys make).
