Overview

Basic Communication

Presentations

Visual Aids


Basic Communication

Communication is the transmission of information from a sender to a receiver

Information is Knowledge communicated.

Data is not information !!!


Basic Communication

Know who the receiver is

Be concise. Keeps the signal-to-noise ratio high

KISS - Keep It Simple Stupid


Presentations


Presentations*

Understand, Plan, Prepare

The audience wants you to succeed

Know what your message is

– 10% rule Handouts !!!

– Tell them ...

– give clues ...

*As outlined in “Technical Presentations”, OE Reports by Richard Gaughan


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



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”



Keeping AudienceInterest*

Ideas Concrete Images

– Imagery entertains– Images are easier to remember

Voice

– volume, tone, rate, diction

Body Language

– face and hand gestures, stance



Visual Aids*

Enhance your message & support your purpose

Provide a framework for ideas

Easy on the eyes, easy to understand, easy to remember



Memory*

Short term working

The rule of 7

Consequences

– 5 to 7 items on a screen– no long text– organization should be self-evident



Visual Aids


Layout

Computer vs Transparencies

Readability

– Templates– Size– Colors– Fonts– Background– Figures, Graphs, & Illustrations


Color vs Black & White

People are visually oriented

Color can help communicate info

Color Transparencies OK if presentation will be given multiple times

Computervs

Transparencies


Templates

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


OrientationPortrait

Landscape

Landscape is better for communicating visual info


Size

1:6 Rule

Floor Test

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)


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”


Font Sizes

Main Title

Key Points

Sub points and other text

reference info or text to read later

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


Graphs

D20%

E13%

F17%

A5%

C35%

B10%

Good for showing % like weight and cost breakdowns

AAE 451

Know the Audience, Know your Purpose

Don’t just prepare lists of data !

Practice

Keep to your allotted time


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.
