Human-Computer Interaction 3e Dix, Finlay, Abowd, Beale
Experiment with HyperCard or another hypertext system if you have access to one. As you work through the system, draw a map of the links and connections. Is it clear where you are and where you can get to at any point? If not, how could this be improved?
This is an experimental exercise which requires access to a hypertext system. It can be used as the basis for a practical class, in which students analyze the effectiveness of the system.
Drawing the map has two purposes: one is to reinforce the overall structure of the hypertext; the other is to test the navigational support that is available. Whether it is sufficient will depend on the system under scrutiny, but possible improvements would be to provide an explicit map, escape buttons, explicit paths to core material. The system may of course incorporate such features.
