Unless EMG signal processing has had some breakthrough in the past 10 years, it is not a very precise interaction mode. I worked in a lab developing it for quadriplegics to use with the muscle on their temple (we tested above the thumb as well). You can get rough 2-axis control with some practice, but that's with an adhesive EMG pad. Can a wrist band get a clean signal?

For typing, I'd expect you need to combine with eye tracking. So you're back to the Vision Pro UI.

On its own, EMG makes a good button, I'd expect. Maybe 1-axis control.

Thanks for the reality check. Wait some more, use voice for now, is what I hear... Although a decade is a long time in signal processing and Meta has dumped a boatload of cash into this.

No 6dof either ?

Sorry for using you as the 'say something wrong, get corrected' research method, but kudos for jumping in. ;}
