Research paper thumbnail of How do people really use text editors

ACM Sigoa Newsletter, 1982

Knowledge workers used an experimental editor, and secretaries used a word processor. Results show a consistent picture of free use patterns in both settings. Of the total number of keystrokes, text entry accounted for approximately 1/2, cursor movement for about 1/4, deletion for about 1/8, and all

In the UDI project we attempted to engineer a usable system. That process involved:defining an appropriate metric for measuring usability,setting explicit levels of usability to be achieveddetermining an appropriate methodology for building usability into the system,delivering a seemingly functional system with an easily changed interface very early in the development cycle, andrecognizing the tentative nature of the initial design.Using the UDI project as an example, each of the above principles will be discussed in detail.

This experience contradicts the idea that user input is irrelevant to the design of command languages. Through careful observation and analysis of user behavior, a mail interface unusable by novices evolved into one that let novices do useful work within minutes. ...

The results suggest three general conclusions: there are large ...

Surprisingly, basic research in human factors is one; the other is ethnographic research about the target audience. Although usability groups often treat ethnographic field studies as expensive adjuncts to usability testing, for strategic usability the reverse is true. ...
