My name is Larry Waldman -- I am a Program Manager on the Office User Experience team and have been working in this role to make Office more accessible for almost 5 years. When users of Office hear that Microsoft has many people working specifically to make our products more accessible to people with disabilities, many express surprise. With such a broad customer base, we recognize the importance of considering accessibility impact in every feature we build. For example, check out this article I wrote about Accessibility and the Ribbon in Office 2007.
Upon starting our research for the 2010 release, we knew it was important to continue our accessibility focus (see Microsoft Accessibility for more info) and ensure that Office 2010 is the most accessible version of Office ever. Not only are accessibility improvements garnering increasing attention from governments, but accessibility improvements provide broad usability improvements and as such are becoming a key area of focus for the software industry in general. With that in mind, we planned Office 2010 with two key accessibility pillars:
Providing detail on all of Office 2010’s accessibility improvements can’t be done in a single blog post, so I’m going to focus today’s discussion on Office 2010’s new document Accessibility Checker feature. I’ll end the post with a few high level bullets of other accessibility features that we might discuss in the future.
While user interface accessibility has been well understood for years, the accessibility of Office document content is a burgeoning new area. In particular, we’ve seen many requests from companies and governments who have been wondering how to help their employees create accessible content. To solve this problem in Office 2010 we created a document Accessibility Checker (like a spell checker, but for accessibility issues) as a core feature of Word, Excel, and PowerPoint.
We started by examining the most common accessibility problems in Office documents and bucketing them in terms of their severity – we ended up with three categories:
Based on these three categories, we came up with a set of issues our checker looks for (described in more detail below) – when presented to the user, they are bucketed into “Errors”, “Warnings”, and “Tips” – these buckets correspond to the above three descriptions.
One of our key principles for Office 2010’s accessibility checker was to make the feature available out of the box for all users – in a way that’s integrated with the authoring workflow. Rather than force users to remember to run the accessibility checker before sending a document, we integrated accessibility results directly into the Backstage view. Anytime you click the File tab and view the Info place, accessibility information will be provided under the Prepare for Sharing header. Prepare for Sharing is described more generally in this Backstage view blog post, but this is the place in the UI where authors go to ensure their file is ready to be shared with other readers; they can check for hidden information, metadata, and now accessibility issues.
To receive more detailed information (including what issues were found, why they are issues, and step-by-step instructions as to how to fix each one), users can click ‘Check for Issues’ and then click “Check Accessibility”.
This will close the Backstage View and open a task pane so you can interactively find and fix the issues in your document. In addition to the screenshot below I’ve provided a detailed textual description of how to use the checker and how its UI is represented to screen readers.
The task pane has two main UI sections.
The top section is a tree view control (with each tree item navigable via arrow keys). Each “violation type” (missing alt text, no table header row, repeated blank characters, etc…) is an item that is collapsible.
When showing, each violation type contains one or more violations – these are represented to screen readers as children of the parent “tree items”. Each leaf is key focusable. For example, if you have two pictures that are missing alt text, they will be two violations under the “Missing Alt Text” node – each can be selected. When a violation is selected, the document will scroll to and select the problematic content.
Where possible we try to name each violation with a meaningful name (for example “Picture 1”) – And in PowerPoint or Excel you’ll find that we also try to provide what slide/sheet the object is on. Note – the violation types are grouped into “Errors”, “Warnings”, and “Tips” – These headers separate the tree items in the view, but they are not collapsible themselves. The group headers are also not key focusable.
When you select an issue in the top part of the pane, the bottom of the task describes how and why to fix it. Just above this bottom section is an “expand/collapse chevron” that allows a user to collapse the bottom pane.
All of the text in the bottom pane section is represented to a screen reader as one big pane with static text. When focus is on the pane, it can be scrolled using ctrl+up/down and pageUp/pageDown. Finally, there is some explanatory text and a more info link at the bottom of the pane if users need more help.
When Office 2010 ships there will be full documentation provided that details each violation the checker will scan for. In the meantime, here is a quick list of what we check for in each Office application – you can download the Beta and try out the Accessibility Checker with your files to see more details for the issues your content has. The top box for each application contains Errors, the middle contains Warnings, and the bottom contains Tips.
While we’ve tried to include as many accessibility issues as we can for Office 2010, we do recognize that there are still accessibility issues we don't yet check for. If you have a particular issue that didn’t make it into this release, please feel free to leave us a comment on this post and let us know things you’d like us to consider for the next version.
As part of our documentation process we’ve provided Assistive Technology Vendors with details about how they can use the Office accessibility platform (including our Object Model) to ensure they optimally read back Office content for their users.
For organizations that are concerned about compliance for employees, we’ve provided several group policy settings that can be used to customize exactly which accessibility violations are checked. Administrators can also increase the visibility and emphasis of the Prepare for Sharing information when there are errors or warnings. Finally, IT departments can leverage Office 2010’s UI extensibility to enforce a workflow that requires users to run the checker – this will help many corporations reduce the risk of employees creating inaccessible content and increase the amount of accessible information available to people with disabilities.
While this post has drilled deeply into the new document accessibility checker, here are a few other highlights we’ll be considering blogging about in the future. Feel free to leave comments and we’ll be sure to drill into what you’re most interested in.
The release Office 2010 is groundbreaking on many levels. Not only are we delivering features to users that provide a great accessibility experience across the PC, the Web, and the Phone, but we have continued to enhance our platform interoperability and commitment to AT Vendors. Hopefully this look at accessibility is useful – please let us know via the comments if you have questions or would like more information on a particular topic.

Update: Nick Simons just blogged about accessibility and the Office Web Apps. Check it out at http://blogs.msdn.com/officewebapps/archive/2010/01/18/9949907.aspx.
Another update: Diana Kimball just published a quick blog about accessibility and PowerPoint. Check it out at http://blogs.msdn.com/powerpoint/archive/2010/01/26/behind-the-scenes-accessibility-in-powerpoint-2010.aspx.
you mention "Issues where content is unreadable". how about your own interface? i do not have vision problems, but what's with all of the washed out text?
take a look at the 2 office related pics on my skydrive. one shows context sensitive menus in the last 3 versions of excel. tell me, which one is easier to read? the text for available options in the newer versions looks like grayed out text in 2003.
then look at the text comparison from one of your blogs. i then pasted the text into word. which is easier to read.
What’s with the allure of gray text? is it more expensive than good old black text.
you want to address accessibility, address in your ui, especially for people with vision problems.
@gkeramidas – As Keri mentioned in her Visuals post a few weeks ago we’ve made a concerted effort to ensure that all text in the (default) silver theme has at least a 5:1 contrast ratio. This is above the rate suggested by some accessibility standards (the current WCAG 2.0 guideline suggests 4.5:1). We hope our visual design polish and high text contrast strikes the appropriate balance for folks, but will keep in mind your feedback for future releases. Thanks again.
Kudos to the Office 2010 for excellent job at the UI and UX for 2010 (especially the sparklines!) :)
One question: Has your team validated HTML pages produced by Office 2010 against other WCAG validators? If so, how well did Office 2010 do?
The Equation Editor still requires some work. Mainly adding Latex writing support.
Do you know about color blindness? Along with quite a high proportion of the male members of the planet I have this condition and while it is by no means debilitating it can seriously affect the usability of UI's such as Word. Simple example: the green and red squiggly lines used for spelling/grammar errors are indistinguishable to me without real effort.
Can you get some colorblind folks on your testing team?
An often overlooked accesibility challenge is mouse usage.
Those with Repetitive Stress Injuries, arthritus, or just poor hand-eye coordination frequently find using mice difficult, painful, and sometimes impossible. Accelerator keys are a huge help for us. Word 2007's hiding of these keyes was a
major step backwards. The alt-activated display is a clumsy
workaround as it is SLOW to display the keys and creates additional visual clutter that is completely unnecessary. How about bringing back underlined letters to signifiy keys? What's more, the drastic reduction of UI customization is
incredibly problematic from a usability and accessibility prospective. Not only are default accelerator keys hidden, but we can no longer add our own. What do we have to do to get these features back?
@Saqib – Thanks for the comments. For Office 2010 we chose not to focus much on improvements to our save to HTML features. Instead, we’ve ensured that there will be an accessible way of viewing Word, Excel, and PowerPoint content through the Office Web Apps – look for a blog post on the Office Web Apps blog (http://blogs.msdn.com/officewebapps) that will talk more about this soon. In addition, if you would like other accessible fixed file format options you can use Office 2010’s built-in Save as Accessible PDF, or you can use the Save As DAISY add-in (http://www.daisy.org/project/save-as-daisy-microsoft).
@Larry - The reason I was asking about save to HTML was that I frequently use the "Publish As Blog Post" functionality in 2007/2010. It is an awesome feature. If I am not mistaken, it uses the Doc -> HTML engine. And it would be really great if the HTML produced for blog publishing meets the WCAG 2.0 guidelines.
@Chris Warwick – Thanks Chris. For Office 2010 we’ve actually looked at our most of our features to ensure that all functionality is possible despite the variety of color blindness (and other differences) that a person may have. While we generally consider red/green (deuteranopia or protonopia) the most prevalent form of color deficit, there are others as well (e.g. tritanopia and grayscale). Given the variety of types of color blindness, we can’t always design features in such a way that all UI works for each person. However, we try to always ensure that each feature scenario is possible in some way for all users – in the case of spell checking, you can press F7 to launch the spelling/grammer checker which hopefully will provide an easier alternative for you to use. We will also take your comments about difficulty distinguishing the underlines into account as we consider how to provide further UI customizations for future versions of Microsoft Office.
Thanks Larry - I have the common red/green kind but appreciate it must be difficult to accomodate all variations without reverting to plain black and white displays. Would it be possible to have profiles/themes for this kind of thing?
There's actually a couple of DWORD values in regkey HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\Proofing Tools called SpellingWavyUnderlineColor and GrammarWavyUnderlineColor that let me specify a hex RGB color value, so I can get by with this for the time being:-)
I can't find the smile program to send a comment on Word, so I'm reporting the error I found here.
The error is that the "Keep Text Only" dropdown isn't working properly. Too see this repeatable error in action, follow these steps:
1. Open Word
2. Create a two by two table
3. Put bullet points in each cell.
4. Change the font to Ariel
5. Copy a text phrase from a Firefox web page into the bottom left box. (For example, "Testing; testing.") The text should be in Calibri font.
6. Chose to "Keep Text Only" via the drop down menu that appears. The text should now be in Ariel font.
7. Inbetween the test phrase, type in a word. (For example, "Testing; One, testing."
8. Copy another text phrase from a Firefox web page into the middle of your statement. (For example, "Testing; One, Two, Three; testing." The text should be in Calibri font.
9. Chose to "Keep Text Only" via the dropdown.
This is when the error occurs; as you'll see, the text "Two, Three;" remains in Calibri format, instead of the Ariel that was intended.
Office 2010 is a big FAIL on accessibility as the File button/menu does not follow Fitt's law and clicking it requires accurately positoning the mouse instead of just quickly moving the pointer to the top-left-most corner and clicking. Imagine if the Start menu stopped following Fitt's law! Please fix this before RTM. The orb in 2007 ribbon apps all followed Fitt's law.
I agree. Clicking in the left most top corner should show the app button menu, not the system context menu.
@Saqib – The HTML Word generates for blog posts hasn’t been specifically improved in Office 2010. However, blog HTML is not the same HTML that’s generated when generically saving a Word document as HTML. Blog post content supports only a subset of features within Word and generates actual XHTML, so its accessibility should be fairly solid. At this time we aren’t making any specific claims related to WCAG 2.0.
@Larry. Thanks for the update. I will test the xhtml produced for blog post against the WCAG 2.0, and post the results here, if that is ok with you.
