Interfaces

Human computing interaction (HCI)

human cognition-> computer processing

• intuitive or complicated?

• rewarding or frustrating

• user-friendly

• cartography

  • abstraction: present real world effectively. There are three types of mechanism that may be used in cartographic abstraction
    • simplification: providing only a limited amount of detail about the world
    • classification: providing information only on certain types of Features
    • symbolization: using coherent graphical symbols to represent features
      • six variables
        • position
        • shape
        • size
        • colour
        • orientation
        • patter

• geovisualization

  • humans use two fundamental different types of though process:
    • verbal thinking
    • visual thinking

Interface design

• GIS Tasks(increased need to engage in geographic thinking)
  • presentation
  • querying (goal-driven retrieval)
  • browsing (relationship-driven retrieval)
  • editing (changes or corrections)
  • integration (combining or conflating)
  • analysis (process to reveal hidden relationship)
  • decision making (evaluating and choosing between different courses of action)
  • problem solving (designing solutions for new problems and unfamiliar domains)
