ABSTRACT
The navigation process in hyper document structures is highly complex. This is due to the vast amount of information, possible pathway options, and richness of visual stimuli. Several studies have reported the effects of different interface approaches and hypertext content structures that produce users misorientation and cognitive overload (Cimino, Elkin & Barnett, 1992). Other studies add information on how these "navigational problems" may be circunstancial due to several users' characteristics. They also approach hypertext research tradition as being much more oriented towards "navigation outcome" rather than "navigation process", and urge research in this field for better understanding users' cognitive processes when interacting with hyperdocuments (Dillon, McKnight & Richardson, 1993).
