A Simultaneous Human and Machine Interface Over a Display Surface
IdentiToy uses RFID Technology for communication and identification, combined with an optically encoded triangulation. The method is far more robust than existing systems which require large flat surfaces to contact the screen, and does not change the normal play / learning value of the object. A single App or OS can automatically recognize 2^64 RFID objects. Granted US patent 9,168,464 . Others Pending US and Foreign.
