It looked like there was a throat mic in the first shot... it seems counterintuitive that you'd get better performance out of lidar on face muscles than on a throat mic.

No throat mic, the first image uses EMG (muscle electrical signal) sensors. A throat mic only works if you're still actually whispering (not fully silent) and is also a weird form factor for a consumer device, which is why we didn't go with it!

		I'll defer to your expertise on what people find weird, but it seems like you should be able to have a throat-based device that could hide under a shirt collar. I have the Meta Ray Bans and even though I love the functionality, I don't care for the bulky frames. And those are designed by Ray Ban, meaning they're presumably at the upper end of what can be done stylishly.
