The use of logging data in the design of a new text editor

Many different human factors techniques are available to the designer of a new computer system. This case study examines how one technique, the use of logging data, was used throughout the design of a new text editor which is measurably easy to learn and easy to use. Logging data was used in four areas: keyboard design, the initial design of the editor's command set, refinements made later in the design cycle, and the construction of a system performance benchmark.
