A “progress bar” might mitigate frustration, Stahl suggested, by signaling that bits were flipping with a purpose somewhere deep inside the C.P.U.

The push to make computers more user-friendly gained momentum in the early 1980s. At a 1985 conference on the nascent field of computer-human interactions, a graduate student named Brad A. Myers presented a paper on the importance of what he called “percent-done progress indicators.” “I had the sense that they were useful and important, and not used as much as they should have been,” Myers says today. (He’s now on the faculty at Carnegie Mellon University.) He told his colleagues that progress bars made computer users less anxious and more efficient, and could even help them to “relax effectively” at work.
