Different elements, such as document title, headings, images, bookmarks, tables, forms, lists, and links were tested with each of the screen reader to understand what were their interpretation and how well did they read a tagged PDF file.Īll the screen readers interpreted couple of things uniformly and correctly “Untagged Document” and “Document reading Order” so the same were not included in the analysis. So I decided to analyze different screen readers running on Windows platform for accessing and testing PDF accessibility. However other screen readers, such as NVDA, Supernova have joined the party and are being today used extensively for testing web pages and PDF documents for accessibility. Over the years JAWS and Window-Eyes were the two screen readers used for testing PDF documents on Windows platform.
Accessibility testing of PDF files involves screen reader testing on Microsoft Windows platform to a great extent.
