Accessibility of Revisions

                                   Is it possible to tag the content of a pdf converted from a word document, that shows track changes in the pdf, so that screen reader users can be notified that the chunk of text has a strike through/has been deleted and that a chunk of text is a different color and was inserted?          

When I use the Adobe Plug-in in Word to convert to pdf I noticed that the chunks of text that have strike through to indicate deletions, and the text that is a different color to indicate an insertion, are tagged as <span> but is there any way to make it more clear to the end-user that the text was marked for deletion or insertion?

At this time, not really. That is in process of being developed, first with the PDF/UA standards and then trickling down to Microsoft and Adobe's software programs.

The <SPAN> tag is used to surround content that has been manually formatted. At this time, Assistive Technologies do not perceive or announce these changes, but that again might be developed down the road.

I'm checking with our accessibility testers to see what they recommend to improve your PDF. Will be back to you...

Hi Bevi! Do you have recommendations for this?

The PDF/UA-2 version of the accessibility standards are still being developed. Can't give you any timeline when they'll be done, submitted to the ISO, approved (hopefully), and then available to the public. But local formatting of text, like the examples, is being discussed.

 

Keep in mind one other factor: implementation by assistive technologies. At this time, the major screen readers do allow users to choose whether to hear certain types of local formatting (like fonts, size, etc. see NVDA's online help RE: this at  https://www.nvaccess.org/files/nvda/documentation/userGuide.html#DocumentFormattingSettings ), but most screen reader users do not change these preferences and, therefore, don't opt to not have these items announced.

 

But as always, any movement on this issue starts with the accessibility committees (WCAG, PDF/UA, and EPUB), then have the standards picked up by our content-creationg/authoring tools (such as Adobe & Microsoft), picked up by the assistive technology manufacturers (JAWS, NVDA, etc.), and finally annnounce this to the user community.

 

Unfortunately, it's a long process. On the bright side, we are in phase 1, the standards. But warning, don't hold your breath. <grin>

 

Remember, at this time, we don't have Microsoft, Adobe, JAWS, NVDA, etc. doing all they could  -- and should  -- with PDF/UA-1, let alone with the eventual PDF/UA-2!

 

Which brings me to my frequent mantra . . . VOTE!

Visit our web site that links you to UserVoice requests for Microsoft and Adobe products at www.PubCom.com/vote  These companies review the vote counts to help them determine which features to program into our tools. Our webpage just makes it easy for you to find the different ideas and requests people have submitted to improve accessibility tools.

 

Vote!

Thank so much for that explanation of the process! Great to know. I will put my vote in right now. 🙂

Here's how we handle it, hope it helps (sorry for the long reply but wanted to give you all the info as we share internally):

Copy Content to Alternate Text and Adding Formatting Meanings

Sometimes file are received that contain specific formatting that has meaning which must be conveyed to the end user.

Because screen readers are not able to read/translate the hightlights or strikethroughs, alternate text must be added to designate where the formatting begins and ends.

In the example shown, there are some highlighted areas which represent the following:

  • Yellow-highlighted text = a proposed addition to the document; and
  • Yellow-highlighted text with a strikethrough = a proposed deletion to the document.

As seen above in the Object Properties, each <Span> tag explains (1) when the formatting begins, (2) the content/text of the tag, and (3) when the formatting ends for that specific text run.

There is no easy way to apply the meanings for each of the text runs that need explanations. However, there is an easy way to copy all of the content to each individual <Span> tag which can speed up this process.

Text can be copied either individually or as a group to either the alternate or actual text area.

Individually:

  • right click on the tag and select Copy contents…; and
  • choose either alternate or actual text.

As a Group:

tag the formatted text with a unique tag type;

  • search for that unique tag (see Section 3.7.3) and select them all;
  • right click on them and select Copy contents…;
  • choose To Alt text; and
  • verify this action by going down the list in the search results window.
    • If there is a tag that shouldn’t have alternate text, uncheck the box that reads, Has alt text .

I believe this statement to be incorrect.

In order to be correct it would have to be rewritten as follows:

"Because screen readers available today have decided not to implement support for reading/translating the hightlights or strikethroughs, it can be useful to add alternate text  to designate where the formatting indicating highlights or strikethroughs begins and ends."

Background color or strikethroughs can be conveyed in a tagged PDF through layout attributes (such as BackgroundColor and TextDecorationType / LineThrough). Screen readers are free to pick up this information.

Hi,

 

I was wondering what software your final image shows? Your first screenshot is familiar - it looks like Adobe. But your second screenshot is an unfamiliar software. It looks like it is useful and I would love to know what it is.

 

Thanks.

 

Olivia

Has there been any new solutions on how to tag strike through text in the year since the last reply?
