Abstract
An electronic learning device for receiving a book having a plurality of successive page spreads, at least one page spread having selectable content and an optically readable page identifier. The device includes a housing configured to receive the book, a position sensor in the housing configured to determine the location of the selectable content on the at least one page spread, an optical sensor in the housing configured to irradiate and detect the page identifier on the at least one page spread and control electronics in the housing operatively coupled to the optical sensor and to the position sensor and configured to synchronize sequential operation of the position sensor and the optical sensor.

8. 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; a 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. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. An electronic learning device comprising:
-
a page having an optical identification code and selectable content; a housing configured to support the page; an optical sensor located in the housing so as to irradiate and detect the optical identification code; a position sensor separate from the optical sensor and located in the housing so as to detect a location of content selected from the selectable content; a controller in the housing operatively connected directly with the optical sensor and with the position sensor and configured to sequence synchronize the irradiation and detection of the optical identification code with the detection of the location of the selected selectable content; and an audible output device controlled by the control electronics to produce an audible response associated with the selectable content in response to the page being supported by the housing and selectable content from the page being selected. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
