Some of this is fair enough, some of it just sounds like the kind of flashy stuff you see in movies but which I'm not convinced of the benefit of. Why would arranging icons and fields as objects around the user improve my experience, beyond impressing me the first few times?
Because it allows a far wider range of possibilities as far as application designs go.
A couple examples...
Books - pages can be sized with respect to the user... as large or as small as the designer desires. Could even exit the limitations of the page - flipping from one text page, then to a large image that occupies a large percentage of your vision, with text that then overlays it on a different 3D plane. Then back to a page.
Using photoshop - instead of having to provide screen space to user interface and buttons, you can have the UI elements down by your waist - they come into view when you look down, but otherwise your entire working view, as large as you want is all image space.
Another is navigation... instead of 2D maps that you look down on, the directional arrows and even traffic data is superimposed over your field of view as you're driving along. No need to look down, and can even provide more information then without (maybe highlighting cars and pedestrians at night).
Or having the QR codes become an AR thing - instead of a link that sends you to a website, instead the cameras on the glasses automatically picks it up and orients it with respect to itself and your field of view. Could be virtual sculpture, or maybe a virtual animal?
Even mundane tasks become awesome... web browsing on traditional 2D planes - except having as many windows as you want, and having them orientate around you freely like floating windows. Have a window with a bunch of links up that you want but don't need to deal with now? Just push it to the side - turn your head and there it is.
Even if these things aren't tickling your fancy, I'm sure once the technology is unleashed that developers will come up with some crazy awesome ideas that will make us go... holy shit, how did we even do without this before?
At that point, even the people that hate on glasses will feel compelled to overcome that barrier. If the only way you can access this new digital world is through these things... you're going to have to really really hate on glasses for that to overcome the awesome potential that's there.
It kind of reminds me of those Windows shells where the desktop is a 3D space and you can physically arrange icons and windows in it. It's flashy and impressive but the usability plummets.
Well the main difference is that these glasses would allow perception in real 3D space, with your hands acting as real 3D space manipulators.
As opposed to pseudo 3D space with a basic 2D pointing device... on a fixed screen size.
I mean... if what I've said hasn't convinced you yet, then no amount of words will. Some people just need to be shown the shit, even use it first hand before they change their minds. Kinda like with the Galaxy Note.
