1. A document data processing system configured for document content re-ordering for assistive technology processing, the system comprising:

  • at least one processor, memory, a touch screen display and a display driver driving a display of a single page of a document by a content reader executing in the memory on the touch screen display;

    an assistive technology also executing in the memory and assistively processing portions of the single page of a document according to a sequence specified by annotations of the portions of the single page of a document; and

    ,a document re-ordering definition module also executing in the memory, the module comprising program code enabled upon execution to enter an ordering mode and during the ordering mode, to sense in the display a drawing of an initial path across different portions of the single page of a document beginning at an originating position of the initial path and ending at a terminating position, to identify an initial sequence from the path, to sense multiple additional, disjointed paths drawn across other different portions of the single page of the document each additional disjointed path defining an additional sequence, to add the initial sequence to a list and also adding to the list each additional sequence and while still in ordering mode, attaching a first one of the additional sequences to the initial sequence in the list, and further attaching each additional sequence to an end of a prior additional sequence in the list so as to define a traversal order of items of each of the sequences for a screen reader, to exit the ordering mode and thereafter to store the list in memory and process the list by transposing the list into meta-data indicative of a combined sequence of the initial sequence and the additional sequence in the list, and to annotate the single page of a document with the generated meta-data so as to direct a screen reader to present different corresponding portions of the single displayed page in accordance with a sequence defined by the meta-data.
