Information display system for electronically reading a book

Claim 1

An apparatus for displaying a video image on a display, comprising: an information storing device having a sheet plate with a plurality of predetermined visual indicia, readable by an operator, printed at locations on the surface thereof, and an integrated memory storing a plurality of packets of predetermined data at addresses corresponding to coordinates of the respective visual indicia on the surface of said sheet plate; location detection means comprising: a first planar panel constituted so that said information storing device is detachably disposed on the first planar panel and including a plurality of electrode wires constituting a grid array of a predetermined pattern along the plane of the panel; a second planar panel including a plurality of electrode wires constituting a grid array of a predetermined pattern along the plane of the panel; and means for supplying electromagnetic signals to said plurality of electrode wires; a pickup sensor connected to said location detection means, said sensor operating in cooperation with said location detection means and said information storing device when said storing device is detachably disposed on said first panel so that said location detection means responds to an operator selecting an indicium by placing said pickup sensor adjacent to the indicium on said sheet plate by outputting a location signal which corresponds to the location of the indicium selected by the operator; a control means, responsive to the information supplied from said information storing device and responsive to the location signal supplied from said location detection means, for retrieving the data from one of said plurality of packets of predetermined data, the data corresponding to the indicium selected by the operator and for using the retrieved data to provide a video signal for displaying an image on a display screen; and means for displaying the image at a desired location on the display screen by placing said pickup sensor on the plane of said second planar panel at a position corresponding to the desired location.

Claim 2

An apparatus for displaying a video image on a display, comprising: an information storing device having a sheet plate with a plurality of predetermined visual indicia, readable by an operator, printed at locations on the surface thereof, and an integrated memory storing a plurality of packets of predetermined data at addresses corresponding to coordinates of the respective visual indicia on the surface of said sheet plate; location detection means comprising: a first planar panel constituted so that said information storing device is detachably disposed on the first planar panel and including a plurality of electrode wires constituting a grid array of a predetermined pattern along the plane of the panel; a second planar panel including a plurality of electrode wires constituting a grid array of a predetermined pattern along the plane of the panel; and means for supplying electromagnetic signals to said plurality of electrode wires; a pickup sensor connected to said location detection means, said sensor operating in cooperation with said location detection means and said information storing device when said storing device is detachably disposed on said first panel so that said location detection means responds to an operator selecting an indicium by placing said pickup sensor adjacent to the indicium on said sheet plate by outputting a location signal which corresponds to the location of the indicium selected by the operator; a control means, responsive to the information supplied from said information storing device and responsive to the location signal supplied from said location detection means, for retrieving the data from one of said plurality of packets of predetermined data, the data corresponding to the indicium selected by the operator and for using the retrieved data to provide a video signal for displaying an image on a display screen; and means for displaying the image at a desired location on the display screen by placing said pickup sensor on the plane of said second planar panel at a position corresponding to the desired location.
