Using Tables and Drawings

Jeffrey Donnell

MRDC 3104

894-8568

2

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

3

For Mini-project presentations

Display

Illustrations of your design(s)

Planning or analysis tools (as called for)

(Limit text to labels and table entries)

Speak

Identify and describe drawings

Identify and describe planning tools

4

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.”

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

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 Evaluation Tables– Which two criteria have the biggest impact on the

rankings?

• For Planning Tools, – How were values determined? – How will the information in [this tool] be used later?

7

Displaying Figures and Tables on slides

• Choose light backgrounds

• Show descriptive slide title OR figure number

• You must describe your figures and tables to the audience:– What is it?

– Why is it presented?

– What should the audience notice about it?

Some planning tools require reformatting for screen display

Second Level Evaluation MatrixConcepts identified by name, by drawing or both

Fonts around 20 pt.

Large font makes criteria easy to see

13

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 used to highlight important information

• Pastel colors give you the greatest flexibility

14

Clustered information permits focus D = Demand W = Wish

15

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

16

Don’t make anything move unless it needs to move!

Any motion is more interesting than you are

Claw arm

Conveyor Belt

Wheels

Arm to steal Opponent Rats/insects

18

Strong colors obscure information. Motion can make us look away from the drawing

19

Mousetraps

Sliders for mobility

Gravity-deployed ramp

Pneumatics for whacking arms

Photographs are not good enough

Light is hard to control
