Truncated experiments and field experiments in usability engineering
Abstract
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.>
