User Centered Design

• What does this mean?

6
User Centered Design

• Design needs to fill the Users needs
• Design needs to enable the user to perform their
  tasks
• Design needs to enable the user to reach their
  goals

7
User Centered Design

• is NOT
• Designers know best
• Users are lazy, stupid, etc
• ? the above leads to failed projects, money
  wasted, and in severe cases, to injury and death.

8
User Centered Design

• The Process Know your users
• What do they need to do?
• Where do they need to get it done?
• When do they need to get it done?
• Do they have any special needs?
• Are there special environmental circumstances?

9
User Centered Design

• What do they need to do?
• What are their goals?
• What tasks do they need to perform to achieve
  those goals?
• Dont just Think about it- go out into the field
• and research it.

10
User Centered Design

• Where do they need to get it done?
• In their office?
• Out in the field?
• Their homes?
• How do these places affect how they get their
• jobs done?

11
User Centered Design

• When do they need to get it done?
• Business hours?
• Early morning?
• After work?
• After hours?
• How does the time affect their performance
• and what can you do to help?

12
User Centered Design

• Do they have any special needs?
• Visual Acuity
• Color blindness
• Deafness
• Physically challenged
• How do these needs affect their performance
• and does this affect your design?

13
User Centered Design

• Are there special environmental circumstances?
• Lighting
• Noise
• Temperature
• Humidity
• Etc
• How do these affect their performance?

14
User Centered Design

• All the above need to be thought of in your usage
  scenarios.

15
Low-Fi UI Prototyping

• So you have done your homework and planned a
  great system. Do you now go and build it?
• NO WAY ITERATE
• Prototype, Test, Fix Prototype, Test, Fix
• Prototype, Test, Fix Prototype, Test, Fix ...
• Prototype, Test, Fix Prototype, Test, Fix

16
Low-Fi UI Prototyping

• Paper Prototype
• Simple object
• Simple computer prototype
• Simulation

17
Low-Fi UI Prototyping

• How deep do you go?
• Narrow and Deep
• Wide and Shallow
• It all depends on what you are looking for.

18
Low-Fi UI Prototyping

• Time Permitting Class Workshop
• Develop a quick paper prototype for the following
  system
• Communications panel for a control tower
• Enable me to choose one of 3 present channels to
  talk on.
• Enable me to choose up to 3 channels to listen
  on.
• Enable me to change the frequency of the 3 preset
  channels
• Enable work in an environment with Red lighting
• Enable me to see at a glance which channels are
  active for talking and which are active for
  listening.
• Enable me to do an emergency transmit to all
  channels
• Be very easy to learn to use
• Enable quick troubleshooting

HomeWork

• Using the User Centered Approach
• Design a quick paper or object prototype that
  takes into consideration your users
• Needs
• Tasks
• Goals
• Next class we will be testing each other.
