Yesterday, I attended to Enrico's rehearsal presentation about tagging and he made an interesting list of existing visual markers:
 |
AR toolkit | |
 |
visual codes | |
 |
spotcode | |
 |
QR code | |
 |
Datamatrix | |
 |
 |
d-touch |
 |
mytago | |
Why do I blog this? to have a kind of list of such technology, just in case one ask... there are the visual representations and the links
