Electromagnetic controllers can be pretty useful, especially for VR headsets like Oculus Quest with inside-out tracking, especially if you want to put your controllers behind your back or when you're shooting while looking away as these types of controllers don't rely on any sensors, inside-out or external.

Here is what I mean by these types of controllers for VR.

I hope Quest S, or future Quests if I can assume, includes these types of controllers. I am looking forward to seeing Oculus ditch the tracking ring solution for the Oculus Touch controllers and go for electromagnetic.
