Is it possible to upgrade the game controller?

Question

Electronics

Good afternoon.
I am actively looking for someone to help me with my problem. I have some device which is a game controller. It is equipped with a trackpad. It is required to make a mechanical upgrade of this device in such a way that the impact on this trackpad is carried out through control from the computer keyboard. For example, so that when you press the "H" key, you press "up" on the touchpad. Here's what this controller
looks like Territorially Moscow.

Answer 1

so that when you press the "H" key, press "up" on the touchpad.

Tell me honestly, do you understand that this is nonsense?
The keyboard is also a controller. Pressing the buttons of one device will not lead to pressing the buttons (or sensor) on the second, but an equal command / signal is easy. Only for this you need not touch the controller, but you just need to "configure" the keyboard or the program in which control is required.
Or use programs that emulate / configure controllers. I'm too lazy to search, but even here I, including recently, answered similar questions a couple of times.
