but the thing that REALLY pisses me off is why do some people think it's ok to invade another person's personal space?
Which is what filming people without their permission can feel like. Is it OK to film someone who doesn't want to be filmed? If you were filming in a public place and someone objected to being filmed what do you say? "It's a free country" or "you can move, can't you?" ... because if someone who is already there, or who can't leave, feels uncomfortable about being filmed by you and you don't stop then you are being a dick and invading someone else's "personal space".
Now, how is anyone supposed to know the difference between someone with a surgically implanted device who is doing research and won't be keeping images for nefarious purposes (something that you would not likely have had any reason to believe exists up to this point) and some a-hole with weird spy glasses and a note he could have written himself saying that he couldn't take them off.
(Besides, it's quite clear that the device is capable of storing images and by the look of the images shown, if these are just images buffered for processing, it looks like processing takes an extremely long time).
The thing is, the article postulates that this is some new sort of hate crime but it's not. People with hearing aids and prosthetic limbs don't get kicked out of McDonald's, but people with cameras can provoke reactions from the people they are filming and that is an old story. If this guy as just walking around filming people all day and at one point in his trip some folks objected and when he wouldn't stop filming them they had grabbed the camera that would still have been an "incident" with possible charges arising though it's quite likely that a restaurant manager would appear justified in acting this way if he had received complaints from patrons. The only thing really new here is that this guy screwed his camera to his head so it couldn't be taken off. What if I got a video camera and attached it permanently to my hand and had my arm bolted so it was always holding the camera up. If some guy asked me to stop filming him and I told him that I couldn't and for the reasons just mentioned, wouldn't that be provocative? If someone gave that excuse to you wouldn't you be tempted to just take the camera out of their hand? If you tried to, is that assault?
Personally I don't think the "hate-crime" thing stands up, and while the situation was uncomfortable and regrettable and got out of hand, I don't feel it's fair to get hyperbolic about this. Augmediated reality isn't really about helping people "see better", it's about augmenting what is visible with things that aren't - like adding GPS data, image and facial recognition, etc. Google glass will have the same issues, but people can take those off if asked by a citizen or a manager of an establishment.
