How have the glasses been received? I don't understand why they're required, is it only to have a consistent mount point for the radar sensor, relative to the face? Have you thought about a throat mic?
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.
