Document interpreting systems
First Claim
1. A document interpreting system comprising a document support member, location detecting means incorporated in said document support member and on which in use a plurality of documents to be interpreted are stacked, electronic pointing means coupled to said location detecting means and adapted in use to be directed at any arbitrary single point on the topmost document of said stack, said location detecting means being arranged to detect electronically through said stack the location of the arbitrary point on said topmost document to which said pointer means is directed, speech storage means for storing speech relating to different points on each of said documents, and speech reproduction means responsive to said location detecting means for reproducing speech stored in said speech storage means corresponding to the said single point on said topmost document to which said pointing means is directed.

Abstract
A document interpreting system comprises a graphics tablet on which a stack of documents, e.g., a book, to be interpreted are stacked, a pointer associated with the graphics tablet and operable through the stack of documents whereby the co-ordinates of an area of the topmost document to which the pointer is directed may be determined, speech storage typically in the form of a compact disc, for storing speech relating to the different areas of the documents being interpreted and speech reproduction meas, typically in the form of a compact disc player for reproducing speech relating to an area of the topmost document to which the pointer is directed.

12. A document interpreting system comprising a document support member, location detecting means incorporated in said document support member and on which in use a plurality of documents to be interpreted are stacked, electronic pointing means coupled to said location detecting means and adapted in use to be directed at any arbitrary single point on the topmost document of said stack, said location detecting means being arranged to detect electronically through said stack the location of said arbitrary point on said topmost document to which said pointer means is directed, speech storage means for storing speech relating to different points on each of said documents, data storage means for storing the addresses of the speech signals stored in said speech storage means, microprocessor means to which the output from said location detecting means is applied for outputting to said speech storage means the data address corresponding to an output of said location detecting means which corresponds to the said single point on said document to which said pointing means is directed and speech reproduction means operable under the control of said microprocessor means for reproducing speech stored in said speech storage means at the said output data address.
