Creating presentations that are accessible to everyone is an important consideration for content developers. Because Adobe Presenter 10 presentations are authored in Microsoft PowerPoint, it is important that the PowerPoint presentation itself be accessible.
Because PowerPoint presentations often contain graphics and animation, it is important to create a document that makes all visual elements available and accessible to disabled users. For example, when a blind user employs a screen reader to access the contents of an online presentation, it is necessary to give all graphics and animations the proper text equivalents to describe their function.
For images or objects (e.g., charts) used in your presentation, add text equivalents (alt text) using the steps below.
- Right-click on your image or object, or select the image or object and press Shift+F10.
- Select Format Picture… or Format Object…
Select the Web tab in the dialog box.
- Enter the alt text in the text area box provided. Be sure this text adequately represents the purpose of the image it describes. This text need not be a detailed description of the image but should convey the image’s function on the page.
- Click the OK button
In PowerPoint 2007 this option is also available but under different headings
- Right-click on your image or object, or select the image or object and press Shift+F10.
- Select Size and Position
- Select the Alt Text tab
- Enter the alt text in the text area box provided. Be sure this text adequately represents the purpose of the image it describes. This text need not be a detailed description of the image but should convey the image’s function on the page.
- Click the Close button
Note: In Word 2007 this option is under Size and in Excel 2007 it can be found under Size and Properties.
