Before and After the Talk
• Face the audience
• Remove your cap
• Introduce yourself and your team
• End the talk with this statement:
“Thank you. I’ll be happy to answer questions.”

Guidelines for Presenting Images
• Describe and explain the diagrams and
charts that you display on the screen
• Use a pointer to highlight the things you
talk about
• Use specific, descriptive words to name
your concepts, their subsystems and their
components
• Avoid Photographs
J. Donnell / ME 2110, 2010
5
Questions to Address During the Talk
• For Systems or Subsystems
– What makes [this] good or bad?
– What should we remember about this design?
• For House of Quality
– What relationships are important?
– What do relationships mean to you as designers?
– How do relationships impact your design work?
J. Donnell / ME 2110, 2010

Displaying Figures and Tables
on slides
•
•
•
•
Choose light backgrounds
Make displays fill the screen
Show descriptive slide title OR figure caption
You must describe your figures and tables to the
audience:
– What is it?
– Why is it presented?
– What should the audience see?
Some tools need reformatting for screen display

A concept diagram for a laser pointer from IEEE Spectrum [1]
Speaking Text: “Intracavity doubling in Mitsubishi’s laser TV begins when an 808nanometer diode laser pumps a neodymium-doped yttrium vanadate crystal. The crystal
emits light at 1064 nm, and then the frequency is doubled (and the wavelength halved)
in either a magnesium oxide or lithium niobate cavity, yielding an output of 532 nm.” [1]

Focus, color and information
• Important information must visually dominate any
figure or table
• When possible, important information should be
clustered and centered
• Color is best reserved to highlight important
information
• Light colors often give you the greatest flexibility
J. Donnell / ME 2110, 2010

Clustered information permits focus

Motion, Sound and information
• Motion should highlight important information
Animated concept drawings are very helpful
Animated Text
Is Not
Helpful
• Sound is best avoided
Unless the sound IS the information
