AccessibleWeb at U February 15, 2007
- Terry Thompson, DO-IT, guest speaker, tft at u.washington.edu
- Topic: PowerPoint & Friends, Accessible Slides on the Web
- Online at http://staff.washington.edu/tft/
- How are you putting PowerPoint on the Web
- Just save it as HTML
- Dump it and rebuild the content in HTML
- Save as Flash
- Terry demonstrated a simple test PowerPoint presentation with
several types of text
- Bulleted lists
- Image
- Data table
- Chart
- Org chart
- Cycle diagram
- List
- All these types of content are built into PowerPoint
- Experimented with a variety of different ways to put it online
- Take outline, paste into dreamweaver, each slide as a div
with a border
- Fairly quick to make the conversion
- Presentation controlled by a CSS file
- Recommendations for this method
- Use PowerPoint templates to ensure good structure
- Avoid inserting text boxes (arbitrarily converted)
- Add alternate text for all images (you can do it in
PowerPoint). Otherwise do it in the HTML
- Add speaker notes to each slide
- Just put the PowerPoint presentation online
- Can be reasonably accessible
- Can navigate with keyboard
- Problems
- Inconsistency in presentation of fonts among
different computers
- Not everyone has PowerPoint
- There is a Microsoft viewer addon to Internet
Explorer browser
- If presentation opens with the browser window,
rather than in a reader application, AT can get
confused in reading it
- Same thing happens if trying to read a PDF
- Speaker notes can be attached to each slide
- Save As to Web
- Save AS Web Page different from Save As, and selecting
Web page
- Save As ... Web Page makes an htm file, with other files
in a folder
- Works best in IE, gets bizarre on other browsers
- Uses VML language, not an accepted standard
- Save As Web Page creates a mht file - everything is in
one file
- Not all browsers understand mht
- Save As PowerPoint presentation
- Screen reader does OK reading content, if it is manual
- Because the alt text of image is in a VML object,
rather than an image, AT cannot read alt text
- Often are automatic, no means of pausing timed
presentations
- Author has option to provide manual control
- Impatica (http://www.impatica.com/)
- Creates a slide show that requires a Java applet.
Requires software on the computer and effort on
- Does not communicate to the screen reader
- To give Java applet focus, click on it. Inconsistent
in its behavior in FireFox
- Can only advance through slides using spacebar. Can
use mouse
- Impatica says their answer to accessibility is the
Speaker Notes - parallel content of slides in Speaker
Notes
- Produce narrated video (Flash or Quicktime)
- Camtasia Studio 4 (http://www.techsmith.com/camtasia.asp)
- Speaker notes are used as captions, displayed as you
go through presentation, making it easy to do
narration
- Adobe Captivate
(http://www.adobe.com/products/captivate/)
- Accordent PresenterPlus (http://www.accordent.com/)
- Standard players usually have good keyboard access, so
should be reasonably available to disabled
- Converting PowerPoint to Adobe PDF
(http://www.adobe.com/products/acrobatpro/)
- PDF accessibility, which is a bit complicate by itself
- Want to create a tagged PDF
- May have to go back in using Adobe Acrobat to tweak the
sequence of elements
- Within Acrobat Pro, can play text to see if it makes
sense
- Does read alt text of images correctly
- Does understand table headings
- Charts are sort of described, but not intelligibly
- Will work best with latest copy of JAWS
- Older versions have much less capability to read PDFs
- Policy question of what versions of JAWS will you
support
- Illinois Accessible Web Publishing Wizard
- Installs in PowerPoint
- Guides creation of accessible presentation
- Creates five separate versions of presentation
- Text only
- Text mostly
- Graphic version
- Solely graphics, text is in graphics
- Outline version
- Handout version
- Can access all versions from within each version
- Solely for export from PowerPoint
- Used to be free, have to pay for it now ($30)
- LecShare (http://www.lecshare.com/)
- Similar to Illinois product, but outputs to one version
- All valid HTML, uses styles, does not use frames
- In charts, actually reads the data generating chart
- Seems to work well with AT
- Also can allow you to do a narration, capturing your
narration and the slides into QuickTime movies
- LecShare interested in a site license for UW
- Have heard about problems with more complex PowerPoint
presentations, especially if they have had large numbers
of updates and modifications, not converting well.
- Abandon PowerPoint and just use HTML
- W3C Slidy (http://www.w3.org/Talks/Tools/)
- Has good valid structure
- Has CSS and Javascript that renders it as a slideshow
- JavaScript gets in the way of using JAWS
- Significant problem
- In attempting to make Slidy emulate the keypad
and spacebar behavior of PowerPoint, they have
disabled the keypad and spacebar behavior of JAWS
- S5 by Eric Meyer (http://meyerweb.com/eric/tools/s5/)
- Standards based
- Does not have problems of Slidy
- Have not had a chance to test thoroughly with JAWS
- Discussion
- LecShare would produce good usable versions
- Making a narrated video would work well, if you can get
presentation author to do the narration
- Have had difficulty getting people to do it
- What kind of presentations are people making
- Speakers like the gee-whiz features
- If there was a site license for LecShare, would people use
it?
- Would have to test it
- Slidy and S5 would be a tough sell to the masses because
they are in HTML, are created without PowerPoint
- PowerPoint was rewritten from the ground up recently, should
be one of the best products in the Office family
- Microsoft products in general seem to not have a cleanup
function. If the code produces something that looks good
enough, they let it remain jumbled. It would be nice if MS
would figure out how to dynamically create clean, standards
and semantic based code, both internally and in exported
versions.
