Following on from receiving my brief from Neil at the Space Centre, about using AR markers embedded in the NSC guidebook, I've been really keen on the idea of using multiple markers, but having them work as buttons - so that actions happen when they are covered up, rather than simply when they are seen by the camera (which is how basic AR apps normally work).
The idea is that I could have multiple markers printed on the pages of the NSC guidebook, one of these would have virtual content registered to it, and the other markers would act as buttons, controlling the content by performing various functions when the user covers them up with their finger. So I've been looking at a couple of examples I've found which use this sort of idea:
FLASH AUGMENTED REALITY DEMO WITH MULTIPLE MARKERS:
This is an example I found on YouTube, from a user called MetzSolo:
It's quite a simple application in essence, but I think it works really well as a demo of this sort of control using markers as buttons, and it also proves that this kind of thing can be done by anyone using Flash, and isn't just reserved for the pros at the big companies with their custom-built software packages!
NISSAN JUKE AUGMENTED REALITY:
Created by Total Immersion - exactly the kind of big company I previously referred to! This example is being used at the moment as a marketing tool for the Nissan Juke car, and has become quite a big hit on the web from what I can gather. It's obviously much more polished, but if you think about how it works, the basic principles are exactly the same as MetzSolo's effort, and probably work in much the same way.
Still, it's fun to play around with. Although you probably can't tell from the video above how much I'm enjoying it!
Now I guess it's high-time for me to get cracking on my own interpretation!
