Visual Markers for camera / Related technologies

Following Bram's post, there are several technologies where visual markers for mobile camera (the target is the phone camera obviously) are involved. I mention here the most known. In the following cases, the purpose is to tag the real environment (objects, space, buildings, etc.) with digital and dynamic content.
The ARToolkit has a poor visual language but is the only one where mixed or augmented reality (i its traditional sense as i think that mixed reality is far more than 3d digital content on top of real world) is involved so far, so has the other ones who look rather like bar codes. They are all context related but semacode and spotcode add interactivity.
