The Human Computer Interaction (HCI), which is a discipline concerned on the one hand with practice, and on the other hand, with the research into phenomena associated with this practice, is studied. Researchers engaged in studying behavioral, social, organizational, and other phenomena associated with interactive computing systems indicate that there is not much linkage between their research and the actual practice in HCI. Research findings are likely to provide basic principles that can account for various patterns and phenomena. Research studies that provide guidelines. Research can facilitate an understanding of the implications of wide versus deep navigation structures, and can fill in gaps between research and practice, which are not covered by guidelines.
