The interface design When developing a presentation, keep the overall design simple and subtle. A consistent background used throughout the presentation will provide a uniform framework in which to display the content. To ensure that interface does not detract from the content, it should incorporate a limited number of colours and fonts, and only highly relevant images. Timing Try to keep the presentation moving at an appropriate and even rate. Display the slides long enough to give viewers enough time to digest the information, but long enough for boredom to set in.
Content Use words to highlight the main points.
A few carefully chosen words augmented with appropriate visuals will hold the audiences' attention better than rambling paragraphs of text. A point form presentation will also force the presenter to speak to the audience, rather than read from the screen. Use one font for headings, and a complimentary font for body text. Depending on the venue, complimentary handouts can be helpful. These provide the audience with a handy place for jotting down notes.
