2.4.3-2 Response Time Appropriate to Tasks

When information from different locations must be compared or mentally integrated, the system response time for information retrieval should be minimized.

Additional Information:
The system response time for display navigation actions, such as selecting displays or zooming and panning within a display, contributes to the information access cost. Performance of mental integration tasks can be impaired when information access costs increase because mental resources are diverted to the information retrieval task. In addition, as system response time increases, the likelihood that information will be lost from working memory increases.
