Patent ID: 8594557

Claim:
An electronic learning device for receiving a book having a plurality of successive page spreads, at least one page spread having selectable content and a page spread identifier, the device comprising: a housing with an upper surface configured to receive the book; a plurality of at least touch-responsive, mutually adjoining individual position sensors organized in a two-dimensional array in the housing beneath the upper surface; a plurality of individual optical sensors located in the housing beneath the upper surface so as to face the page spread identifier of the received book, each optical sensor including an optical emitter; a microprocessor controller in the housing generating control signals identifying each individual position sensor and each individual optical sensor in a sequence for sequential activation of the individual position and optical sensors; and a driver circuit in the housing receiving the control signals from the microprocessor controller, the driver circuit being connected with each individual position sensor of the array and with each individual optical sensor of the plurality and being configured to respond to the control signals from the microprocessor controller to activate the individual position sensors of the array and the individual optical emitters in the sequence.
