c. Set-Up
When giving a presentation, you need to set the stage both
figuratively and literally for success. The way you set up a
presentation room will have a great impact on the audience’s
perception of you and your message. By manipulating the
placement and use of the following tools, you will improve the
impact of your presentation.
Lighting—Good lighting is an important component of a
successful presentation. You should strive to create an unequal
distribution of light. An audience should always see as much
of the presenter’s face as possible, so most of the light should
be focused on you. Because it is important for you to be able
to read the audience’s faces and body language, some light
should be shed upon them. However, no light should shine
on the screen.
Stage— When presenting on the same level surface that your
audience is on, most people can only see the top one-third of
your body. Therefore, it is recommended that when giving a
presentation to an audience of 25 or more, you stand on a
stage or platform. As more of your body is visible, the easier
it is to communicate with an audience.
Podiums—The best presenters avoid podiums because they
hide 75% of the body and restrict movement. However, many
people feel more comfortable with a podium to hold their notes
and hide their discomfort. If you must use a podium, angle it
at 45 degrees to the audience so that you are not completely
hidden.
Visuals—It is imperative that you make sure your visuals are
large enough and projected far enough for the audience to
see. Eight times the height of an image is the optimal viewing
distance to read 24 point type. The bottom of a screen should
be at least 1.8 meters above the floor.
Screen—The screen should always be in the centre of the
room so that all audience members can see it. Because people
read from left to right, you should always stand to the
audience’s left when discussing visuals.
Seating—Arrange seating according to the dynamics of your
presentation. If the presentation is more than half-a-day, use
classroom style seating—a chair and a desk. If you would
like to encourage audience interaction, use chevron seating,
angling the chairs into a “V” shape. When you have a very
small audience, a “U” shaped arrangement will increase
interchange.Good Bad Good

d. Rehearsing & Delivery
•The best time to rehearse is the day or evening before,
not a couple of hours before, and the best place to
rehearse is in the actual room. Rehearsing a speech
in a small office is not the same as standing up in
front of 100 people in a hotel ballroom or classroom.
•Due to varying processor speeds of computers,
practice your slide transitions for proper timing.
•Whenever possible, set up your equipment well in
advance to allow adequate time to resolve any
unexpected issues such as lighting, power, seating
and audio.
•Thoroughly check every piece of equipment you bring
along.  Make sure you have fresh batteries in your
remote controls and laptop computer. Fully charge
your computer’s battery before the presentation and
connect your AC adaptor for added safety.
•Make sure you are completely familiar with the control
panel on your projector and remote controls.
•If you are using a microphone, check it out before
hand and walk around to see where you might have
problems with feedback. Avoid standing in these
problem areas during your presentation.
e. Presentation Tips
•Before beginning, visualise yourself delivering an
outstanding presentation.
•Know your speech, memorising at least the first three
minutes of your presentation will allow you to focus
on your rhythm and pacing.
•Speak to early arrivals to help you build a rapport
with the audience and make you feel more
comfortable.
•Do not be overly dependent on your visuals by reciting
what your audience is already reading. Know your
material well enough to be able to deliver the
presentation with ease. Use your visuals to emphasise
keypoints.
•Be sure to project your voice clearly and use eye
contact to maintain audience attention.
•Do not wait until half way through your presentation
to get your point across. If you wait and try to create a
“build-up”, you may lose some of your audience along
the way.
•Keep your audience’s attention. As most people only
focus for 15 to 20 minutes during a one hour
presentation, it is important to recapture their attention
periodically. Use phrases like, “This is critical to my
point” or “This is absolutely fundamental” to remind
them you are saying something they need to hear.

Aspect ratio
Width and height ratio of an image. The normal aspect ratio of a computer and video image is 4 : 3. There are also wide images with an
aspect ratio of 16 : 9 and 21 : 9.
ANSI lumen
Brightness unit established by the American National Standards Institute.
Auto sync
Optimises projected computer images by automatically adjusting certain characteristics.
Background
Initial setting image projected when no signal is being input.
Clock
Clock adjustment is used to adjust vertical noise when clock level is incorrect.
Compatibility
Ability to use with various image signal modes.
Composite sync
Signal combining horizontal and vertical sync pulses.
Digital keystone correction
Function to digitally correct a distorted image when the projector is set up at an angle.
Dot by dot mode
Mode that projects images in their native resolution.
Enlarge
Digitally zooms in on a portion of an image.
Fit to screen
Function to adjust an image without keeping a native aspect ratio other than 4 : 3, and project it in a 4 : 3  ratio.
Freeze
Function to freeze a moving image.
GUI
Graphical User Interface. User interface with graphics that allow easier operation.
I/P conversion
Function to convert an image between “Interlaced” and “Progressive” scan displays.
Intelligent compression
High quality resizing of lower and higher resolution images to fit the projector’s native resolution.
IrCOM
Function to transmit still images from a computer, hand-held PC or digital still camera via infrared communication for “Wireless
Presentations”.
IrDA
Standard protocol for wireless communication.
IrTran-P
Standard format (protocol) for transmission of images.
PDF
Portable Document Format. Documentation format used to transfer text and images from the CD-ROM.
Phase
Phase shift is a timing shift between isomorphic signals with the same resolution. When phase level is incorrect, the projected image
typically displays horizontal flicker.
Presentation tools
Helpful tools used to emphasise keypoints throughout a presentation.
RS-232C
Function to control the projector from the computer by using the RS-232C ports on the projector and computer.
Startup image
The image displayed when the projector is turned on.
Status function
Displays the settings of each adjustment item.
Sync
Synchronises the resolution and phase shift of two signals. When receiving an image with a resolution different from that of the computer,
the projected image may be distorted.
Sync on green
Video signal mode of a computer which overlaps horizontal and vertical sync signal to green colour signal pin.
Wireless mouse control
Function to operate the mouse control of the computer with the supplied remote control.
XGA resolution
The resolution with 1,024  768 pixels that uses the signal of an IBM/AT compatible (DOS/V) computer.
