Brad A. Myers's 1985 work introduced a concept in the design of progress indicators; what is the term for this origin?

• A. Loading indicators study
• B. Percent-done progress indicators
• C. Progress bar origin
• D. User interface metrics

Answer: (C)

The idea being tested is where the concept of the progress indicator, specifically the progress bar, originated in design. Brad A. Myers’s 1985 work helped establish and popularize the visual metaphor of a bar that fills to show how much of a task is complete. Naming the origin of that concept as the “progress bar origin” makes sense because it points to the moment and idea that gave birth to this common UI element. Other options describe either a broad area (user interface metrics), a general type of indicator (percent-done progress indicators), or a study of indicators rather than the originating concept itself (loading indicators study). They don’t capture the notion of the origin of the progress bar concept the way the chosen term does.
