Information and Function Chunks as Building Blocks in the Control Room of Life

Abstract

Inspired by work on systems for control rooms, this chapter describes how working with information on the Internet and other types of network-based information systems can be made easier by applying ?ve principles: 1. by providing information to the user about any changes to the information that may affect him or her;2. by dividing information and functions into chunks—the smallest possible meaningful units;3. by automatically synchronizing navigation and parameters in different chunks;4. by using views that each gives access to chunks that are relevant in a speci?c situation or for a speci?c task; and5. by sharing information from one terminal to another as needed.
