HCI Design Principles

  • Know your user

    – This can be hard when your user group is very general

  • Reduce cognitive load

    – This concerns designing so that users don’t have to remember large amounts of detail

  • Engineering for errors

     – Engineering for errors includes forcing a user to prevent him or her from making an error or at least make it more difficult

  • Maintain consistency and clarity

    – You can maintain consistency by using standard operations and representations and from using appropriate metaphors that help to build and maintain a user’s mental model of the system
