I'm pretty skeptical about people's ability to multitask like this. We all like to think we can do several things at once but many studies have shown we're basically interrupt driven single-tasking organisms. You simply cannot walk and watch where you're going while also watching something in your glasses. People think that having the screen overlaid onto reality solves the problem, but the problem isn't really visual in the first place, it's mental. Try even reading a (real) sign while walking along and you'll find you're bumping into people, dangerously strolling across roads without looking, etc. I really want these to work, and I can see in limited situations (manually turn them on to look something up, etc.) they could. But I really deeply doubt they can work they way people are imagining.
