What is Accessibility?
Wikipedia
Defines accessibility as being the degree to
which a product, device, service or environment
is available to as many people as possible.
What is Accessibility?
(continued)
Microsoft
Defines accessibility as making something that
can be usable by anyone – including those with
disabilities.
Since it is difficult to find out specifics about our
audience, we need to create documents and
presentations that are as accessible as possible
for everyone.
Accessible PowerPoint Presentations
Why?
• Better screen reader navigation
– Screen readers read a presentation using synthesized
speech for the blind and low vision
– Introduction to the Screen Reader
– Screen reader Demonstration
• Better communicate content to all people
– Sufficient structure and contrast to enable a
presentation to be understood
How to Navigate this Presentation
• Slides are presented in 3 ways:
– Why: Presents the rationale for the required or
suggested guideline presented
– Hands-on/Try It: Complete the activity specified on
the slide
– How-To: For reference only. Read the information so
that you will know how to accomplish the task
presented at another time
• Have fun!

SLIDES
Ensure that Slides Have Unique Titles
Why?
• For those who cannot view slides:
– Slide titles are used for navigation
– Slide titles are used for selection
• Example: If two slides have the same title, there
will be no distinction between them when read
by a screen reader
• Proceed to the next slide where you will notice
that the slide contains the same title as this slide
Ensure that Slides Have Unique Titles
Why?
1. This slide contains the same title
as the previous slide
2. Read the Tip reported for this slide
in the Inspection Results Pane
3. Change the title for this slide
–
Replace the word Why? with
the word Continued
Add visible titles to your slides:
1. Select Outline View from the pane
2. Place the mouse pointer to the right of the Title slide
box for this slide
3. Type a unique name
Tip:
To restore a deleted slide placeholder text box,
select Reset from the Slides Group on the Home
tab.
Create an Invisible Slide Title
Why?

slide title remains on the Outline
Verify the Reading Order of Objects
Why?
• Screen readers:
– Cannot display all of a slide’s content at once
– Read content in the order that they are added to a slide
• Information must be coherent when read aloud

may not be in the correct order to be read
Verify the Order of Objects
Hands-On: Try It
1. Return to Slide view
2. Proceed to the next slide

order
Note: The bottom most item in the Arrange panel is read first
4. Select the Re-order
arrows to place the
item in the correct
reading order.
Create Meaningful Hyperlinks
Why?
• Screen readers scan documents for links and will
read them
• Hyperlinks must be descriptive to the end user
• Hyperlinks that are typed in full will be helpful for
people who will be reading presentations
converted to printed material
Create Meaningful Hyperlinks
Examples
• Example of a non-descriptive link:
– Hands-on training is available for instructors on the methods and
best practices to create accessible Word documents for students.

Best Practices
SLIDE DESIGN
Use a Pre-defined Slide Layout
Why?

presentations and the Web:
– Sans-Serif Fonts
• Example: Verdana, Arial, Tahoma
Choose a Suitable Font Type & Size
(continued)
• Reserve underlined text for links
• Fonts no less than 24 points
– Text needs to be readable from the back of a room
Choose Suitable Colors
Why?
• Color blind people have difficulty reading:
– Combination of red and green or
– Combination of green and yellow
• Color used to indicate a point of interest cannot be
discerned by the visually impaired (i.e. the
required items are in red)
– Use an * to indicate a point of interest

Best Practices
PRESENTATION TECHNIQUES
Oral Presentations
IN THE CLASSROOM
Oral Presentations
Prepare & Distribute
• Address all errors and warnings in the MS Accessibility
Checker
– To ensure that distributed materials are accessible
• Distribute the presentation electronically before the live
presentation
– To enable the visually impaired follow along with the
oral delivery and help the learning disabled process
more content
Oral Presentations
Slide Design
• Ensure fonts are 24 point & above
– To ensure that the presentation can be read from the
back of the room
• Use a minimally-patterned slide background
– To avoid disrupting the information presented
• Provide sufficient contrast
– Sometimes the contrast needs to be more pronounced
for projection
• Remove excessive animation or flashing elements
– Flashing text, transitions, & animations can cause
migraines or seizures
Oral Presentations
Deliver
• Indicate slide transitions with a sound or vocal
announcement
– To indicate that new content is being introduced
• Describe information available only in visual or auditory
format such as pictures, tables, graphs, audio clips, music
– Those with visual or auditory loss focusing on the
speaker will be made aware of the information being
presented
Online Presentations
BLACKBOARD & WEB
Blackboard & Web
Prepare
• Before posting or distributing
– Address all warnings & errors in the MS Accessibility
Checker
• Deactivate automatic transitions
– Enable those with learning disabilities to view a
presentation at their own pace
Blackboard & Web
Caption
• Include a transcript for embedded audio
–Ensure deaf and hard of hearing can track what’s being
presented in the video
• Make captioning available for embedded video & player and
ensure that controls are accessible
–Those with disabilities need a clear way to read and
listen to audio & video
• Use the notes pane to hold a transcript of a narrated slide
show that will be read by screen readers
–Enable the hard of hearing to read content and screen
readers to read to the blind
Blackboard & Web
Communicate
• Ensure that color is not used to convey content
–The visually disabled will not be able to distinguish
meaning by color
• Check reading order of text boxes that are not part of the
native slide layout
–Usually the last thing read by a screen reader
Blackboard & Web
Post
• Post unprotected PowerPoint to enable people to modify
fonts (size, type, color), backgrounds
–Clear, clean, and simple text is the best way to effectively
relay information
• Do not post html version
–html does not reproduce slide titles making navigation
confusing
