There are many a time when (for better or worse) a speaker
decides to use an overhead projector to enhance a presentation.
This, more often then not, can destroy not only the presentation
but the integrity of the speaker, if not handled properly.
Overheads are a powerful tool in a presenters arsenal. They help
convey ideas, drive particular points home as well as giving one
the ability to display charts, graphs and pictures clearly. The proper use and preparation is of utmost importance when using
a tool such as this.
Here are some points you must ask yourself before using this
tool:
Is it necessary for me to use an overhead projector?
A) What value does the projection add?
B) Could more value come from using flip-charts, posters
or handouts?
Now, if you have decided that an overhead is necessary, this is
what you must do:
get your thoughts in order
make up your transparencies
A) don't put your whole speech on transparencies, just key
points and ideas
B) limit each visual to one idea
C) keep transparencies simple - no more than six lines per
transparency, no more than six words on a line
D) use 18 point type or larger to make it easy to read
E) don't use more than two type styles on any single
visual
F) mix upper-case letters for easy readability
G) use a common background theme for associated
transparencies and ideas
H) don't use exclamation marks, even from a short distance,
they look like the number one
pre-test your hardware so you know it's working
A) use a graphic image with text (one not used in your
presentation) to test equipment and focus
B) most overheads can only effectively project for a distance
of up to 20 feet; make sure your projector is within that
space
position material on the upper part of the projection
surface
view your overheads from all angles, especially the sides and
back of the room, to ensure they'll be clearly read and
understood by everyone
don't turn off all room lights when using a projector
A) if this is not possible, bring a lamp or two on low
dimmers to help your audience see you; this also allows you to
see any notes you may be using
turn the projector lamp off while changing slides or during
discussions
never stand or place anything between the projection and
screen or wall as it visually distracts and distorts
information
when you must point to details on overheads, use a pen or
pencil, place it on the slide and get your hand out of the
picture
If someone is working the projector for you, use a laser
pointer to point at the screen but keep in mind that this can
eliminate the color red from your slides
give people time to read and mentally process what's on the
screen
talk to your listeners not the screen
Although this list is not complete, it will help get you started with your presentation. For
