VRCodes started as PhD thesis work. Thus, there is a plethora of references surrounding the result of this work. Some of these public disclosures are included as reference here.
In November, some applications of VRCodes will be shown at the International Symposium for Mixed and Augmented Reality 2012
The abstract announcements in 2012 were recorded as both a part of the MIT Media Lab and MIT CSAIL. The slides for that talk will be available online here.
