Usability Glossary: redundant modalities


using more than one way to represent, display, and enter data, such as:

  • using both a beep an a menubar flash to notify a user of an error
  • using text to label images redundantly
  • allowing a user to issue commands by typing or selecting something with a pointer
Redundancy provides flexibility for different user preferences, system configurations, or user abilities.
