Agenda

• How to organize the talk• The deliverables we need to see• How to use and display graphics:

– Specification lists– Function trees– Morph Charts– Concept drawings– Evaluation Tables

• Warnings about slide design• Plagiarism

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 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

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 D = Demand W = Wish

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
