ABSTRACT:
A teaching toy (8) includes at least one receptacle (12). Receptacle (12) has a conductive signal-out pad and a plurality of conductive code-in pads (46) at an inner surface. At least one remote unit (14) is included which is removable from receptacle (12). Remote unit (14) has multiple sides and a conductive signal-in pad for capacitive coupling to the signal-out pad. Remote unit (14) also has at least one conductive code-out pad (50) electrically connected to the signal-in pad for capacitive coupling to one of the code-in pads (46). The signal-in pad and the code-out pad (50) are disposed on a first side of unit (14). Remote unit (14) also has a datum disposed on a second side. A processor (20) is included for generating a control signal to the signal-out pad and detecting data signals from the code-in pads (46). Processor (20) associates the data signals with and generates data representing the datum. A memory (22) is included which stores instructions for operating processor (20). An interface device (27) receives the data from processor (20) and communicates the datum to a user.
