Good visual aids will highlight your speech. To avoid mistakes and display your information efficiently when using the appropriate visual aids, follow these guidelines:
Make slides and overheads easy to read by avoiding too many words per line, too many colors, and designs that are too busy or too small.
Check text for spelling errors.
Take advantage of computer software templates that help you design visual aids.
You know you need time to design slides and overheads.
Number all your slides and overheads.
You can’t check the working condition of the slide or overhead projector too many times.
Bring an extension cord and adapter.
