Technology users are technology observers as well, monitoring for problems or opportunities that might arise. Designing interfaces to support the monitoring of technology presents unique challenges, like detecting situations and knowing how and when to respond, coping with a changing operating environment, and the changing knowledge of the observer.
Conrad describes "Heed," a scale and framework to help observers of a system evaluate which situations need scrutiny and when. He gives an example heed-based interface that encourages the development of situation awareness. Learn how the framework and interface can be applied in three different scenarios: server performance, a business's finances, and user experience in a community forum.
