While the current trend
in the training industry is heading toward the use of the LCD Projector technology,
the overhead projector is still the most popular presentation device used today.
Most facilities have an overhead projector in every training room or conference
room. Although it is the most widely used, it is also the biggest abused. Some
presenters continue to misuse the overhead projector even though they have used
them for years.
I have provided below some
basic guidelines and tips when using an overhead projector. Although some of
these tips seem like common sense, many presentations fail because these basic
tips are not consistently applied.
Here are some tips and rules
to be aware of:
- Practice giving your
presentation using your visual aids - to check out how well they project.
This is a good time to also check for spelling errors. Have a friend sit and
watch your presentation and make notes on any problems or needed improvements
with your visual aids. Practice using your overhead transparencies so you
will be comfortable with handling them correctly.
- Stand off to one
side of the overhead projector while you face the audience - Too many
people stand between the overhead projector and the screen causing a shadow
of the presenter's body. Standing to one side will allow the audience to see
you as the presenter and will prevent you from blocking their view of your
visual aid.
- Do not face the "projected"
image on the screen - Face your audience and not the screen. Many presenters
face the screen and end up talking to the screen.
- Cover the transparency
when you are done using it - with an opaque piece of cardboard (I usually
mount a solid sheet of paper on one of my transparency frames). You may also
turn off the projector completely, but beware; this can cause the projector
bulb to burn out sooner.
- Bring a spare bulb!
- Nothing is more unsettling than to have your overhead projector bulbs burn
out during your presentation. Bring spare bulbs and a glove to change the
bulb. The old bulb will be HOT! Make sure you know how to change the bulb.
CAUTION: Remember HOT glass looks the same as cold glass!
- Place the overhead
to your RIGHT if you are right handed and to your LEFT of you are left handed
- This will make it easier for you to face your audience and write if you
need to. In either case, you want to stand in the center of the speaking area
and face the audience when you speak.
- Place your overhead
projector on a table - low enough so it does not block you or the screen.
Have a small table next to the overhead so you can stack your overheads before
and after you use them.
- Place your screen
on a diagonal instead of directly behind you - this will assure that you
do not block the view for your audience. Also, have the top of the screen
tilted forward towards the overhead projector (if possible) to prevent the
"keystone" effect (This is where the top of the image is larger than the bottom).
- Tape the power chord
to the floor - to protect you or someone else from tripping. As the presenter,
tripping over the chord and falling, although humorous, is one large gesture
you would prefer to avoid.
- Store your overhead
transparencies in a sturdy box or container - so they will stay clean
and protected for the next time you need them. Label the box and include a
"clean" copy of your handouts in the box. This will make it easier for you
the next time you give your award winning presentation again.
