Question 1

______ is a one-direction flow direction of information, _____ allows for interaction.

Answer 1

Display is a one direction flow direction of information, interface allows for interaction.

Question 2

What is a static display?

Answer 2

Displays the same information consistently.

Question 3

What is a dynamic display?

Answer 3

Displays different information over time.

Question 4

Five Perceptual Display Principles:

Answer 4

• Make displays legible
• Avoid absolute judgement limits (Max 5-7 levels)
• Top-down processing (Highlight unexpected)
• Redundancy gain (Multiple cues or modes)
• Discriminability (Similarity creates confusion)

Question 5

Two Mental Model Display Principles:

Answer 5

• Principle of pictoral realism (Configure to match system/mental model)
• Principle of the moving part (Match movement to system/mental model)

Question 6

Four Attention Display Principles:

Answer 6

• Salience compatibility (Make information noticeable)
• Minimizing information access cost (Minimize “distance” between variables)
• Poximity compatibility principle (Link variables through common location, color, or other code)
• Principle of multiple resources (Distribute information between mental resources)

Question 7

Four Memory Display Principles:

Kno

Answer 7

• Knowledge in the world (Display information rather than rely on memory)
• Support visual momentum (Grounding info when looking between data)
• Predicitive aiding (Show future states rather than force people to esimate)
• Consistency (Same cues should have same meaning)

Question 8

Configural Display:

Answer 8

Arrange/integrate multiple instruments/information sources so they are viewed as a sinlge item/object.

Question 9

Benefits of Configural Display:

Answer 9

• Exploits top-down processing and mental model
• Uses gestalt grouping principles
• Aid with predication

When everything is ok, there should be symmetry

Question 10

Benefits of HUD:

Answer 10

• Reduced information access costs
• Conformal images (overlays) support divided attention tasks
• Collimated imagery

Question 11

Costs of HUD:

Answer 11

• Clutter
• Hard to read imagery
• Hides events in the real world

Question 12

Advantages of HMD:

Answer 12

• Minimize info access costs
• Can impose images over greater range of the far domain
