Truncated experiments and field experiments in usability engineering
Mark Chignell, J.F. Valdez · 2002
An assessment is made of the role of truncated experiments in usability analysis, and experimental results are used to indicate some of the problems that occur in truncated experiments. A discussion is presented of the use of field studies to provide supplementary information for usability analysis. A description is given of some of the logging tools the authors have developed to make comprehensive field studies more practicable.>
