The patented system defines a method by which an object or device can interact with a video screen. The system is able to locate the position of and identify the type of object placed on a display screen. In addition, the system can actuate actuators on the object and read the status of sensors on the object, enabling a full rich interactive experience.
The triangulation component is typically based on an optical signal. Optically based triangulation works by optical scan through modulation of the screen or backlight.
The identification component of the IdentiToy system works by passive RFID. Usually RFID Tags contain a unique Identifier which is for example a 64-bit long sequence of ones and zeros, which can encode (264) = (a very large number) of different Identities. The RFID transponder both energizes and reads out this unique identifier.
The IdentiToy system picks up the optical signal and adds it to the 64-bit unique toy identifier to yield a sequence which encodes both position and type of object. The sequence when read by the display device’s RFID interrogator yields both the type and position of an object. Further two such RFID tags, or a single tag coupled to two optical receivers placed within the same object can be used to triangulate the orientation of an object on the surface of the display. Objects that are multifaceted such as dice can have optical sensors on multiple surfaces. Both RFID and the optical receiver are powered by the NFC field with a size that is 3 mm diam x 10 mm long cylinder.
It can be seen that due to the large number of unique ID’s possible, that the IdentiToy System can be implemented in the OS and always be subliminally interrogating its surroundings and automatically launch the relevant app in the proximity of an IdentiToy based device.
