The W3C WAI specification states that moving objects and text should be avoided if at all possible; this is because moving items at certain frequencies could induce seizures, and also people with cognitive disabilities may have problems viewing slides with moving text and graphics.
You will notice that the last two slides in the original Human Computer Interaction PowerPoint presentation contained moving text and transitions. This is not uncommon in PowerPoint presentations; transitions between slides are easy to accomplish and makes for a bit of decoration for viewers of your presentation. Furthermore, many presenters prefer to "hide" certain items on a slide until they "reveal" them, so often you will see bullet lists that slowly reveal their content as you select the "next" button. While this works well in a live presentation with a presenter in control, it does not transfer well to an on-line, HTML-based presentation. It is better to make the contents of the slide static and non-moving so that you avoid possible problems and accessibility issues.
For this reason, it is recommended that all slide transitions and animations be removed when converting slides from PowerPoint to accessible HTML.
