Comprehensible Fault Handover in the Control Room
The project examines how an interface can make incomplete state visible during fault handover. Completed in the scenario; the prototype comparison is illustrative.
Problem
At handover, the origin and age of a message are often missing. The person taking over can then hardly judge how reliable the displayed state is.
Research question
How can an interface make incomplete state visible without suggesting false certainty for action? The aim is a presentation that shows uncertainty while still enabling action steps.
Method
The basis is a task model and two interface variants, which are worked through in a cognitive walkthrough using fictitious procedure cards. The work took place in the interaction studio.
Evaluation criteria
The criteria are the visibility of critical information, traceable action steps and documented risks of misinterpretation. This is an expert inspection, not a usage study.
Expected outcome
Completed in the scenario. The illustrative output is an annotated prototype comparison. There are expressly no empirical usage data.
Limits
No study took place in a real control room, and no safety-critical operating approval is given.
