This was a solved problem in the 1st and 2nd generation of AirPods with tap controls[1]. I'm still surprised that they removed that feature in favor of pressure, although now that I'm reflecting more on it, I wonder if it's part of Apple using their manufacturing and engineering as a moat[2]. i.e. Tap controls are relatively easy, so once wireless earbuds became commodities, they had to figure out some way to differentiate themselves.

That said, as someone who does pottery (messy hands), wears gloves/hats (stuff in the way), and has relatively poor fine motor control, I guess I welcome any solution that doesn't mean getting clay or cold air in my hair/ear.

The battery consumption and latency of the IR cameras will be interesting though. Too sensitive, and you'll eat up your battery. Not sensitive enough, and UX suffers.
