My guess is it's simply the knowledge of the image. Of the demo of the
walking miniature horse the cube I was holding was a block of wood with
paper black and white images glued to it. A kindergarten kid could have
made it. There was no RFID. I'm guessing it must work off a highly
specialised OCR algorithm but instead of trying to decipher 26 letters, 10
numerals and a handful of punctuation marks; it is just one, or 6 in the
case of a cube, but from multiple angles and orientation. In the case of a
cube the angle never has to be less than 45° because once you go below that
another side/image becomes dominant as it rises above 45°. An improvement
on the QR Code algorithm maybe?

Always appreciate your glass half full (if not overflowing) viewpoint
