Bokode - micro barcodes using your camera to scan
OK. I'm definitely struggling with the science - but the concept - tiny little micro tags which are machine readable by *any* regular camera - that is totally cool
The Camera Culture group presents Bokodes, tiny imperceptible
barcodes that can be read by a standard camera positioned up to four
meters away to decode identity, and six-degree-of-freedom pose (angle
and distance).
