Content Filters

  • User controls restrict list of content items
  • Used instead of search or navigable categories

Common controls

  • Radio buttons and menus for choosing just one criterion
  • Checkboxes for multiple selections
  • Paired controls for ranges (beginning to end or range)
  • Text boxes for keywords

Issues

  • Intersection or Union?
  • Granularity of restrictions
  • Ordering the controls

Examples

Discussion questions

  • How do you clearly communicate that multiple items will expand or narrow search?
  • How do you decide the criteria for filtering retrieval?
