Designing
Effective Visual Aids
1.
Make
certain that you practice your presentation with your visual aids to be sure
they are readable.
2.
Keep it
simple. Limit amount of information on each overhead or slide. You should use
only one figure, one table, or a few lines of text to emphasize a single
idea.
3.
Use the
visual aids as a guide. Do not read
the information to the audience.
4.
Be aware
of problems when using colors. Avoid colors that blend together.
5.
Avoid too
many slides or overheads. Use them as an aid; do not overwhelm the audience.
6.
Know how
to position and operate the projectors.
Overview of Visual Aids

Overhead
Transparencies
Pro/Cons of Medium
·
Easy and
inexpensive to prepare.
·
Room need
not be darkened, which allows you to have contact with the audience.
·
May write
on them during presentation.
Technical tips
·
Turn off
the projector when it is not in use.
·
Learn how
to change to the back up bulb which should already be in the machine.
Production
·
Do not
simply make a Xerox transparency of normal typed material. It will not be
legible on the screen.
·
If you
can stand and read the transparency when it is lying on the floor, the type
size is adequate.
·
Keep text
font large, no less than 30 points.
·
Lay out
vertically (portrait) only.
·
Limit
amount of text, highlighting key words or phrases
·
Keep wide
margins, at least 1”, around all sides in case machine distorts.
·
Number
the bottom of each page in order of presentation, in case they drop on the
floor!
·
Bring a
hard copy of your overheads and blank overhead sheets (that can go into a
copier) in case one disappears.
Slides
Pro/Cons of Medium
·
Increased
expense and time required for design and preparation.

Technical Tips
·
Allow one
to two minutes per slide. This avoids using too many slides and gives the
audience time to interpret the information.
·
Use the
80- slide carousels. The 140-slide tray commonly jams.
Production
·
Keep
layout simple and limit each slide to one major concept.
·
Readability
is maximized by following the 6 x 6 rule: no more than six words per line and
six lines per “page” of text.
·
Dark
background with light colored lettering the best. White background and black
letters causes eyestrain.
·
Lay out
horizontally only.
·
Number
bottom/front of slide frame for easy loading.
PowerPoint
Pro/Cons of Medium
·
Presenters often experience
technical problems with the hardware or software.
·
Can be compatibility issues if
bringing own laptop
·
Can incorporate audio/video.
·
Can update/change presentation easily.
Technical Tips
·
Bring backup on zip disk, CD or
floppy formats.
Production
·
Follow same guidelines as for
slide production.
