I'd find this difficult to tolerate at work. I can't imagine anybody addressing me with one of these. Not only that I am certain no work place I have worked at would ever buy something like this. And they're all happy to spend thousands of dollars on things which would improve our productivity.
I was ready to dismiss the idea until I saw the end of the video. I think outside of business/work it could be quite useful (as demonstrated by the art gallery).
The art gallery idea struck me as interesting at first.
On second thought, however, why would you want to look at art through a low quality iPad camera when you could browse a website with high-res images of the same stuff?
I'm not sure that usage would pass the gimmick test after the novelty wore off.
Another complication is navigating through the museum without violating the personal space of the visitors. I guess they could only be allowed in the after hours but then how do you prevent the experience from deteriorating into high-tech bunch bumper cars.
