- Make high frequency inputs easy to express (.e.g Y/N, OO, defaults).
- Let the user specify the unit of measurement; don’t require transformations or calculations!
- Provide meaningful groupings to break up long input formats.
- Allow abbreviated input when it can be unambiguously interpreted (Yes or Ye or Y).
- System should be ‘case blind’ when it really doesn’t matter (YES or Yes or yes).
- Provide defaults whenever possible; allow simple (single key) acceptance of defaults; decide whether system, session or file defaults are appropriate; make it clear which is which, if systems provides both kinds of different contexts.
