[symic]

A person recording on a phone is not participating in the event. They are, for the most part, observing. Others may be able to see their expressions and whatnot but they are generally not interacting with the person doing the filming. It remains to be seen if people are willing to interact with someone wearing, what will appear to be, ski goggles. Apple may not have solved the issue but they clearly spent a vast amount of money/time/effort to make it so that interacting with someone wearing the headset isn’t too weird. We will see if they got it right or close enough to right.
