The audience will read everything on the screen themselves-it’s human nature. Slides are not a teleprompter! Presenters should never read the slides to the audience.
Presentations should be a visual aid for the audience, to support and reinforce what a presenter is saying. Slides are for the audience, not the presenter All text displayed on screen should be legible (easy to distinguish letterforms) and readable (arranged for easier reading) by everyone in the audience. Successful presentations rely on great type to help convey information to an audience. Good typography can make or break any design effort, including presentation design.
