Online dynamics

The authors describe ways in which technical communicators can use dynamic online interface techniques to give users effective, optimal-complexity information. Research from electronic media is applied to online interfaces, with particular attention given to the visual dynamics of filmed material, visual complexity in online information, visual sequences and transitions, and the auditory dynamics of representational media. It is suggested that the most effective design principle seems to be that a moderate amount of visual and auditory change can make displays appealing to users and lets them know where they are in tasks. Designers, in an attempt to make displays interesting, may overwhelm users with too many dynamics. Media such as hypertext, which promise increased flexibility and integration of other electronic media, may require designers to be particularly careful about the capabilities of their users.<>
