X-Ray Vision via Augmented Reality

The Wearable Computer Lab at the University of South Australia has recently uploaded three demos showing some of its researchers' work to Youtube. Thomas covered one of those, AR Weather, but fortunately enough, he left me with the more interesting work (imho).
The next clip shows a part of Benjamin Avery's PhD thesis, exploring the use of a head mounted display in order to view the scenery behind buildings (as long as they are brick-walled buildings). If understood correctly (and I couldn't find the relavant paper online to check this up), the overlaid image is a three-dimensional rendition of the hidden scene reconstructed from images taken by a previously positioned camera.

The interesting thing here is that a simple visual cue, such as the edges of the occluding items, can have such a dramatic effect on the perception of the augmented scene. It makes one wonder what else can be done to improve augmented reality beyond better image recognition and brute processor power. Is it possible that intentionally deteriorating the augmented image (for example, making it flicker or tainted), will make a better user experience? After all, users are used to see AR in movies, where it looks considerably low-tech (think Terminator vision) compared with what we are trying to build today.

Anyway, here's Avery himself, presenting his work and giving some more details about it:

I guess I didn't see the other two this morning when I made the post. I blame it on a lack of coffee.

The x-ray view was very interesting. From my own experience with Dactyl Nightmare and the various outdoor AR or the pit AR that I've seen, I'm impressed how realistic it looks even though the graphics aren't hyperreal. I think our minds fill in some missing details because its "expected", especially with a 3D view.
