One of Kurzweil's primary features is its ability to convert inaccessible PDFs into accessible PDFs, but what does this mean?
Inaccessible PDFs often:
Accessible PDFs include:
While professors and others who assign work to review should be always already working to make their PDFs accessible, there will be many times where users will need to convert an inaccessible pdf into an accessible PDF. Some PDF's may be too inaccessible to convert without an inordinate amount of labor required. However, Kurzweil's innate PDF recognition software should be able to help users through the majority of cases.
Kurzweil PDF conversion can function on two levels:
On another page, users may have read the detailed tutorial on opening files in the browser and desktop Kurzweil application. When a PDF is opened in a Kurzweil application, two things will happen:
While the application automatically attempts to make PDFs accessible, sometimes mistakes linger that have to be fixed more directly. Two examples of this include:
There are two quick fixes to each of these errors.
Rotating pages in Kurzweil is as simple as clicking a button:
While Kurzweil scans and attempts to recognize text on every document it opens, sometimes a PDF's quality prevents full OCR (Optical Character Recognition). When confronted by this problem, users have several options across both the browser and desktop applications. This box will only cover the manual text re-recognition. For text zone editing and direct OCR editing, see the Advanced Accessibility Formatting box below.
While the Kurzweil browser application will often automatically produce a better OCR scan than the desktop application when opening a file, there is a manual OCR option.
Manual OCR in the desktop application is relatively more simple than in the browser application.
For many documents, the above steps are more than enough to produce an accessible PDF, and can start reading and generating study guides. Some documents, PDFs in particular, require more intensive editing. The next box covers advanced accessibility editing.
Some documents may be more difficult than others for Kurzweil to scan and convert into OCR text. Sometimes this is due to complicated text layouts, in which multiple headers, footers, footnotes, and text boxes crowd a page. Sometimes, a document's text may be so poorly readable due to scanning errors or handwritten notation that Kurzweil cannot determine where text begins and ends.
Kurzweil's advanced tool for users looking to convert inaccessible PDFs to accessible PDFs is the Zone Editor. The Zone Editor allows users to manually draw text zones, or sections of the page where text is found, for OCR scanning on the page. The Zone Editor can also demarcate the order of read text during text to speech, and also main body text from header and footer text. As established in other sections of this resource guide, this section will introduce users to zone editing in both the browser application, and then the desktop application.
Users may have already seen the zone editor page in the browser application by following the steps to re-recognize OCR text in a document in the previous box on this page. Regardless, opening the zone editor is simple.
Zone editing in the desktop application is, arguably, simpler than it is in the browser application. In order to get started:
In this page, users have learned several ways to make texts more accessible using OCR scanning. These newly accessible texts can now be used for Kurzweil's main study functions: text to speech; and detailed annotation.
