A few months ago I put together a library that lets you use a Nintendo Switch JoyCon 1 (the JoyCon 2s can't connect to bluetooth) or a Playstation VR controller to a Mac in order to control the mouse, use a radial menu, etc: https://github.com/jturnshek/JamCon

I map one of the keys to voice input push-to-talk for handy: https://handy.computer/

This involved reverse engineering and writing new drivers for both (with no existing reference for the PSVR). It's all in that library, so if that sounds interesting to you, you can probably get Claude/Codex/whatever to convert it to a Windows app pretty quickly.

I haven't been maintaining this tool actively, but maybe it's useful to someone.
