A hypertext information system should show how a destination node is related to the point of departure.
Additional Information:
Disorientation can occur when users do not understand the relationships between successive views of a display system. In hypertext-based information systems, disorientation can occur when making transitions between nodes of the information structure if the relationship between the information in the current and previous nodes is not clear. The basis for a link should be apparent to the user through explanatory text or graphical display techniques. Disorientation may also occur when looking at an overview display after making a transition between nodes. Successive views of the overview display may look quite different due to the complexity of the links between the nodes. For example, when a new node is selected, a new set of relational links may be presented in the overview display.
