The BasicPump design

  • Text menus have many of the advantages of pull-down menu systems but they can be controlled from the keyboard and so avoid the necessity of having to transfer attention to the mouse.

  • Command line systems can be the most powerful for experienced users but can be intimidating to novice users.

  • The syntax of command line systems should be as regular as possible and designed with care.

  • An effective help system is essential for command line interfaces.

  • Feedback in a command line system should include a history list of commands issued.

  • Any user interface should be effective, efficient and enjoyable.

  • Evaluation of an interface by the use of structured investigations can be very powerful, but it is also very expensive.

  • Evaluation of an interface by the use of heuristics is the most cost effective way of improving its usability, particularly when it is carried out by a usability expert.
