I have a market research question for you:

The reason we don't currently have this is that smart glasses (being small) can't fit a big battery. Our recording time is about twice that of Glass (ours is 1 hour) but that's still not enough for the all-day recording you envision.

So, my question is, would you be willing to wear a thin wire (slightly thicker than a headphone cable) going from your glasses to your pocket to keep your glasses charged, if it enables this use case?
