Creating Effective Visual Aids

Page 2: Visual aids

Visual Aids Should…

Outline, explain, support main points

Serve audience’s needs, not speaker’s

Be simple and clear Supplement and support…

NOT DOMINATE!... the presentation

Page 3: Visual aids

Be Visible

Use Sans Serif fonts (fonts without feet) e.g. Arial, Tahoma, Trebuchet, Verdana, etc.

Titles should be 32-44 pt. font size, BOLD Text should be as large as possible

First level 24-32 pt font size Second level 20-28 pt font size Etc.

Use color wisely Contrasting colors

Page 4: Visual aids

Red/Blue Conflict

Red letters on blue backgroundcreates “flicker effect”

Blue letters on red backgroundjust as bad

Page 5: Visual aids

Low Contrast

White on yellow Yellow on white

Black on blue Blue on black

Page 6: Visual aids

Avoid These Combinations Examples:

Green on BlueDark Yellow on Green

Purple on BlueOrange on GreenRed on Green Don’t !

Page 7: Visual aids

Colors

White on dark background should not be used if audience is more than 20 ft away.This set of slides is a good example.You can read the slides up close.The further away you get, the harder it is

to read.This is a good color combination if viewed

on a computer.A dark background on a computer screen

reduces glare.

Avoid White BackgroundsThe white screen can be blinding in a dark room

Dark Slides with Light Colored Text Work Best

Don’t !

The Color Wheel• Colors separated by

another color are contrasting colors (complementary)

• Adjacent colors harmonize with one another (Green and Yellow)

• Colors directly opposite one another are said to CLASH

• Clashing colors provide readability – Orange on Blue

Do !

Page 10: Visual aids

Colour - Good

Use a colour of font that contrasts sharply with the background Ex: blue font on white background

Use colour to reinforce the logic of your structure Ex: light blue title and dark blue text

Use colour to emphasize a point But only use this occasionally

Page 11: Visual aids

Colour - Bad

Using a font colour that does not contrast with the background colour is hard to read

Using colour for decoration is distracting and annoying.

Using a different colour for each point is unnecessary Using a different colour for secondary points is also

unnecessary Trying to be creative can also be bad

Page 12: Visual aids

This is a good mix of colors. Readable!

Background ColorsRemember: Readability! Readability! Readability!

This is a bad mix of colors. Low contrast.Unreadable!

This is a bad mix of colors. Avoid brightcolors on white.Unreadable!

Page 13: Visual aids

Background - Good

Use backgrounds such as this one that are attractive but simple

Use backgrounds which are light

Use the same background consistently throughout your presentation

Page 14: Visual aids

Background – Bad

Avoid backgrounds that are distracting or difficult to read from

Always be consistent with the background that you use

Page 15: Visual aids

Graphs and ChartsMake sure the audience

can read them!

Page 16: Visual aids

Avoid using graphics that are difficult to read. In this example, the bright colors on a white background and the small font make the graph hard to read. It would be very difficult to see, especially in the back of a room.

Graphs - Good

Use graphs rather than just charts and words Data in graphs is easier to comprehend & retain than

is raw data Trends are easier to visualize in graph form

Always title your graphs

Eye Movement

The “Z” Rule

Page 28: Visual aids

Illustrations

Use only when needed, otherwise they become distracters instead of communicators

They should relate to the message and help make a point

Ask yourself if it makes the message clearer

Simple diagrams are great communicators

Do !

Preparation - Slides Use Images & Graphics

Relevant images communicate, and maintain interest

Displaying Visuals: Tips

Select visuals purposefully What visuals illustrate a point? Make

a claim? Help to prove an argument? Design easy-to-read visuals

Are the visuals easy to read by all members of your audience?

Draw attention to aspects of visuals How will you draw attention to certain features of the visual?

Page 32: Visual aids

Displaying Visuals

Insert needed visuals Use color Resize appropriately Draw attention

That was purelygratuitous!

Page 33: Visual aids

Choose Color Carefully

Similar intensities draw attention but makedetails hard to see.

Strong, clean contrastdraws attention, makesdetails easy to see

Page 34: Visual aids

Simplify and Draw Attention

Animating: Tips

Custom animation allows you to animate text, visuals, or line work

Custom animation should be used purposefully (and sparingly!) Animating should help audience

comprehend your message Don’t animate solely for aesthetic

purposes

Page 36: Visual aids

Limit Each Slide to One Idea

• Use Bullet Points to Cover Components of Each Idea

Page 37: Visual aids

Bullets

Keep each bullet to 1 line, 2 at the most Limit the number of bullets in a screen

to 6, 4 if there is a large title, logo, picture, etc. This is known as “cueing” You want to “cue” the audience on what you’re going to say

Cues are a a brief “preview” Gives the audience a “framework” to build upon

Page 38: Visual aids

Bullets (con.)

If you crowd too much text, the audience won’t read it Too much text looks busy and is hard to read Why read it, when you’re going to tell them

what it says? Our reading speed does not match our listening

speed; hence, they confuse instead of reinforce

Page 39: Visual aids

Points to Remember

Limit each slide to 1 idea Limit each bullet point to only a few words to

avoid long sentences that go on and on! Limit animation – Too much animation can be

distracting. Be consistent with animation and have all text and photos appear on the screen the same way each time. There are many animation modes to choose from, but it is best to use just one throughout.

Do not do this!Limit Bullet Points

To a few words

Page 40: Visual aids

Points to Remember

Keep bullet points briefUse the same background for

each slideUse dark slides with light

colored text in large hall events

Do !

Page 41: Visual aids

Avoid the “All Word” Slide

Another thing to avoid is the use of a large block paragraph to introduce your information. Attendees do not like to have what is on the screen, read to them verbatim. So, please use short, bulleted statements and avoid typing out your whole presentation on to the slides. Also, it is difficult for some to listen and read a large amount of text at the same time.

Don’t

Page 42: Visual aids

Limit Animation

Use the same animation throughout the entire presentation Using more than one can be very distracting

The audience will only see the animation and not the message you’re trying to get across

!

Bam!Don’t

YOU

Do not use the media to hide you The audience came to SEE you The media should ENHANCE the

presentation, not BE the presentation If you’re only going to read from the slides,

then just send them the slides! Remember, only you can prevent “Death by PowerPoint”
