13% of the population are deaf or hearing impaired. 1% of the population are visually handicapped from color blindness 5 % of the population have visual conditions not correctable by glasses. Its the law: Section 508 of the Rehabilitation Act (29 U.S.C. 794), as amended by the Workforce Investment Act of 1998 (P.L. 105-220), August 7, 1998. Best Practices for Slide Layout
Always add text after applying a slide layout. Using a Slide Layout template avoids the chance of random objects hiding on a page and ensures that the same content visible to sighted users is accessible by all assistive devices. Formatting Accessible Slides To choose a slide layout: select Layout located under the home tab and select the appropriate slide for your content.
All text should be viewable in the PowerPoint's outline view. Text typed in a text box will not be viewable in the outline view. Creating Slides Titles Best Practices for Slides Titles are to create them with a Title Holder rather than a Text Box. Title holders are available in almost all slide layouts.
Text Box vs. Title Holder The Title Holder has not been used if text next to the slide icon is not showing. All text must appear in Outline View. Fonts Use recommended fonts such as: Times New Roman Verdana Arial Tahoma
Helvetica Avoid the use of text shadow To remove shadow text, highlight the shadow text and click the S symbol located under the home tab. Additional Considerations for Textual Content Avoid the use of slide animations and
flickering/flashing text. Text containing hyperlinks should display the fully qualified URL (i.e. http://www.cdc.gov/and not www.cdc.gov). Slides containing hyperlinks should have active links. Graphics and Images When using a graphic, select a slide layout that
incorporates an image placeholder. Insert the graphics/image using the placeholder. Do not paste images directly into he slide. All graphics/images require an alternate text (alt text) description. Adding Alternate Text All graphics must have Alt Text. If image is decorative or background, apply empty alt-text.
In order to add Alt Text: Right click on the image/graphic Select Format Picture Select Alt-text Add title and Alt Text description in the space provided. Grouping Images and Graphics An illustration created from several smaller images must be grouped to form one image/graphics.
Select image/graphics, right-click, and used select Group. Grouped images/graphics will need Alt Text Charts and Graphs Charts should be labeled appropriately with Title, Legend, and Axis labels. Charts are considered complex images and should include a text description directly under the chart. Example Chart
Line graph showing monthly page views to the NCHS website by year, from 2005 through 2009. Page views in 2009 show increases ranging from 10 to 33 percent over monthly totals in previous years. Tables Tables should be created within PowerPoint using the Table feature, located under the Insert tab. Tabular data should not be displayed through the use of tabs and spacing. Tables should have Logical relationships between data Labeled column and row headers Title, number (if applicable) and description
Example Table Table. Calories consumed and hours of exercise, by work day: week of June 13, 2010 Monday Tuesday Wednesday Thursday Friday
Calories Consumed 2000 2100 1900 1700 2500
Hours of Exercise 1.0 1.0 0.5 1.5 0.0
PowerPoint Themes Themes with pre-selected backgrounds and fonts can be problematic for accessibility. Many themes use shadow text for Slide Titles. Slide backgrounds and fonts can also be an issue for users with color blindness or users with low vision. Choose a theme that has good color contrast between text and background. Modifying the Slide Master
Modifying the Slide Master allows you to remove problematic text shadows once rather than every time a new slide is created. To edit the Slide Master: select Slide Master located under the View tab. Remove text shadow from all slides in the Slide Master. Fonts and colors can also be customized within the Slide Master. Adding File Properties All accessible PPTs must have properties associated
with the document: Select File, Properties Provide information for the following fields: Author (ex. National Center for Health Statistics). Title Subject Keywords
To Set language: Select Review, Language Saving the Documents Best practices for saving the document: Use alpha numeric characters. Use underscores instead of spaces. Files names should not contain spaces or special characters (e.g., !, @, #, $, %). File name should be limited to 20-30 characters. File name should be indicative of the content presented.
Review Text Images
Create all slides using pre-built slide layouts Always use the Title Holder for slide titles All text must appear in the Outline view. All images require an Alternate Text descriptions. Graphics made with multiple parts must be grouped. Charts and tables should be labeled appropriately and should be created using PowerPoint.
Modify the Slide master to remove problematic fonts, styles, and colors from Slide Layouts. Check Document Properties and File Name Resources HHS Accessible PowerPoint Checklist http://www.hhs.gov/web/policies/checklistppt.html
