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.”

J. Donnell / ME 2110, 2010 5

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 6

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 7

Displaying Figures and Tableson 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

Speaking Text: “Intracavity doubling in Mitsubishi’s laser TV begins when an 808-

nanometer 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 16

Clustered information permits focus

Motion, Sound and information

• Motion should highlight important information

Animated concept drawings are very helpful

• Sound is best avoided

Unless the sound IS the information

Animated Text Is Not Helpful
