Basic Communication
Communication is the transmission of information from a sender to a receiver
Information is Knowledge communicated.
Data is not information !!!
![Page 4: © Purdue University Creating Effective Presentations Developed by Jason Bowman for AAE451 School of Aeronautics & Astronautics Purdue University Based](https://reader035.vdocuments.mx/reader035/viewer/2022062717/56649e615503460f94b5cc62/html5/thumbnails/4.jpg)

Basic Communication
Know who the receiver is
Be concise. Keeps the signal-to-noise ratio high
KISS - Keep It Simple Stupid

Understand, Plan, Prepare
The audience wants you to succeed
Know what your message is

Engaging the Audience*
Effective speakers
– engage to occupy the attention of– entertain to cause time to pass pleasantly– impress arouse strong interest
Conversely the speaker would
– bore the audience– ensure a forgettably unpleasant experience
*As outlined in “Technical Presentations”, OE Reports by Richard Gaughan

What You’re Up Against*
The audience has many concerns
– where to have lunch– who’s going to win tonight’s game– relationship/family issues
“The more of their attention you engage,the more their minds are working with you,and the easier it is for them to hear andremember your presentation”
*As outlined in “Technical Presentations”, OE Reports by Richard Gaughan

Keeping AudienceInterest*
Ideas Concrete Images
– Imagery entertains– Images are easier to remember
Voice
– volume, tone, rate, diction
Body Language
– face and hand gestures, stance
*As outlined in “Technical Presentations”, OE Reports by Richard Gaughan

Visual Aids*
Enhance your message & support your purpose
Provide a framework for ideas
Easy on the eyes, easy to understand, easy to remember
*As outlined in “Technical Presentations”, OE Reports by Richard Gaughan

Memory*
Short term working
The rule of 7
Consequences
– 5 to 7 items on a screen– no long text– organization should be self-evident

Color vs Black & White
People are visually oriented
Color can help communicate info
Color Transparencies OK if presentation will be given multiple times

Consistent look
– Pictures and illustrations preferably on left
Sequence
– user knows where to look for info on every slide– animation and builds: upper left to lower right

Colors
Hot White, Yellow, Pink, Red
– attract the eye– use sparingly and for emphasis
Cool Gray, Green, Brown, Blue
– use for support and reference
10% (?) of the male pop has a color blindness

Background Colors
Cool colors
Less distracting
Lower intensity. Other items stand out.
One solid color for all slides (template)
![Page 20: © Purdue University Creating Effective Presentations Developed by Jason Bowman for AAE451 School of Aeronautics & Astronautics Purdue University Based](https://reader035.vdocuments.mx/reader035/viewer/2022062717/56649e615503460f94b5cc62/html5/thumbnails/20.jpg)

Foreground Colors
Hot colors
High Intensity
Choose one primary color, but not brightest.
One color for emphasis
– usually the brightest– use sparingly

Fonts: Serif vs Sans Serif
Serif
– good with written text but not with projections
Sans Serif
– more visually appealing– but 1 is the number one and l is lowercase “ell”
![Page 22: © Purdue University Creating Effective Presentations Developed by Jason Bowman for AAE451 School of Aeronautics & Astronautics Purdue University Based](https://reader035.vdocuments.mx/reader035/viewer/2022062717/56649e615503460f94b5cc62/html5/thumbnails/22.jpg)

Fonts vary in physical size

Readability
About 6 words (?) is enough.
No more than 7 lines per slide
In builds, previous lines use darker colors
About 2 minutes / slide
ALL UPPERCASE IS DIFFICULT TO READ

Longuski's Timing Rule
Allow 2 minutes per page for a highly interactive presentation (e.g. thesis defense).
Allow 1.5 minutes per page for a noninteractive presentation (e.g. a presentation where there will be no questions or questions only at the end)
Note: count all viewgraphs including title and repeated ones.
