I think that niche of travelling which requires your hands is definitely worth it. This is the reason why I don't like using a bike for long journeys.
That is a relatively small niche, they are looking for something much bigger. I personally can't see the use of wearing one, but then again, i still have a feature phone.

Like your ideas though, hopefully third party devs can make them a reality (I'm guessing battery is the issue on the persistant video recognition stuff). Seriously upbeat about this, it could change lives
