Abstract
Abstract A reading system includes a computer and a mass storage device including software comprising instructions for causing a computer to accept an image file generated from optically scanning an image of a document. The software converts the image file into a converted text file that includes text information, and positional information associating the text with the position of its representation in the image file. The reading system has the ability therefore to display the image representation of the scanned image on a computer monitor and permit a user to control operation of the reader with respect to the displayed image representation of the document by using the locational information associated with the converted text file. Also described are techniques for dual highlighting spoken text and a technique for determining the nearest word to a position selected by use of mouse or other pointing device operating on the image representation as displayed on the monitor.
