The main Trigger word is "PS2". You can also specify controller and console.

I would also recommend prompting for the text on the controller. For example:

the text on the controller logo says "Sony". Under the left button the text says "Select", under the right button the text says "Start", under the center button the text says "Analog"

Tired of ugly warped controllers? Well this aims to fix that. It's not perfect (I'm still a beginner) so you may have some issues. So far the biggest problem is that it REALLY doesn't like showing the back of the controller, so if your character is facing the camera, they will most likely be holding the controller upside down.

Sorry about that, I'm still learning!

I am planning on doing other consoles as well in the future and those will hopefully be improved.
