But the 'rock on' thumb swipe still feels a little uncomfortable. Especially when I get used to gesturing with my right hand, and then I have to carry my arm over my body to get to the Mute/UnMute.
Have you considered just pulling in some American sign language? The controls (mute, tile, etc.) could even have a depection of the hand symbol.
We've explored a bit of the ASL space. The motion based ones are not something we've dug into. But some of the "static-but-location" based ones are things we've tried.
"Mom" is easier than "grandmother". We've tested out a version of "mute". "Tile" would be quite a bit harder (I think).
Interesting, is there any reason you didn't just use your left hand for the Mute/UnMute? Was it too uncomfortable with your non-dominant untrained hand? Or did we not do a good job of communicating that the gestures work on both sides?
And then when I raise my hand and the menu pops up, I realize it would have been easier to use my left, but already committed to right.
