DESIGN PRINCIPLES

Don Norman, Design of Everyday Things.

Seven design principles:

  1. Provide a good conceptual model
  2. Make things visible
  3. Get the mappings right
  4. Exploit the power of constraints
  5. Design for error
  6. Provide feedback in response to actions
  7. When all else fails, standardize

DESIGN PRINCIPLES

Nielsen’s heuristics

  • Visibility of system status
  • Match between system and the real world
  • User control and freedom
  • Consistency and standards
  • Error prevention
  • Recognition rather than recall
  • Flexibility and efficiency of use
  • Aesthetic and minimalist design
  • Help recognize, diagnose, and recover from errors
  • Help and documentation

ROBOT UIs

Unique challenges of robotics

  • Complex: Distributed, asynch
  • High DOF
      • Input: How to allow users to control all robot DOFs
      • Output: How to visualize the state of the robot
  • Irreversible state, no immediate resets
