If you though the array of tech-abbreviations was used up, here is another one: RFIG (Radio Frequency Identity and Geometry transponder).

Mitsubishi Electric Research Lab is working on ways to extend RFID tags by adding a photo-sensor. Objects that are tagged can have their data (size, annotations, 3D position etc) presented by using a hand-held mobile projector, called an RFIG Lamp, thus augmenting the information and making RFID interaction more intuitive.
