Visual Search

• Explanation
• Certain primitive features are perceived in a
  parallel form, whereas other features require
  serial scanning
• Application
• Cockpit Displays

34
Sound Localization
35
Sound Localization

• Explanation
• We are capable of identifying the location of
  sounds because of the discrepancy at which they
  reach our ears
• Application
• Auditory Displays

Fitts Law

• Explanation
• Movement time is a function of the distance
  between targets and the size of the targets
• The shorter the distance between two targets, the
  shorter movement time tends to be
• The bigger the size of the two targets, the
  shorter movement time tends to be
• Application
• Graphical User Interface Design
