Displays and design Flashcards
What can be described as windows to the task or system?
Information Displays
General Principles Related to
Display Design
- Give good feedback
- Use good mappings
- Provide a conceptual model
- Make things Visible
What are the Perceptual Principles of Display Design?
•Make Displays Legible (or clearly audible, texturally disparate, etc) •Avoid absolute judgment •Top-down processing •Redundancy gain •Discriminability
What is redundancy gain?
When the same message is expressed more than once, particularly if the presentation is in alternative physical forms.
What is the Principle of Avoiding Absolute Judgment?
Do not require users to judge the level of a
variable on the basis of a single sensor variable
like color or size, which contains more than five
to seven possible levels.
What are the two Mental Model Principles of Display Design?
- Principle of pictorial realism
* Principle of the moving part
What is the Principle of pictorial realism?
A display should look like the variable that it
represents.
What is the Principle of the moving part?
Display variables move similarly to the way the
actual parts move.
What are the three Attention Based Principles of Display Design?
- Minimizing information access cost
- Proximity compatibility principle
- Principle of multiple resources
How do you Minimize information access costs?
Keep
frequently accessed sources in such a location that the cost of
traveling between them is small.
What is the Proximity compatibility principle?
Sometimes two or more sources of information must be mentally integrated to complete the task. Parts of the information should be close together, but not too close
What is the Principle of multiple resources?
Dividing information display between
modalities (audition and vision).
Multiple cues to identification.
Icons accompanied by words.
What are the three memory principles of display design?
Put Knowledge in the world
Principle of predictive aiding
Principle of consistency
What is the Principle of knowledge in the world?
Visible reminders or
statements of what is
to be done.
(ex: post-its)
What is the Principle of predictive aiding?
Help with making
prediction in the
future.
