Designing Adaptive User Interface with ZTS

User-friendly has become a cliche for software systems and it's too often talked about but not attained. The Zero Training System (ZTS) makes software easy to use once one is comfortable with computer- based systems. Three principles underlie the adaptability of ZTS to various tasks and levels of user expertise. The first, dialogue specialization, provides a range of dialogue modes including command line entry, menu selection, form filling, function keys and questions. The second, within-dialogue adaptation, uses different adaptive strategies to enable a single dialogue-type to accommodate a range of user abilities and goals. The third, between-dialogue integration, which creates parallels among commands, menus, forms and questions.
