Evaluating Usability and Challenge during Initial and Extended Use of Children's Computer Games

摘要

This paper describes a study that examines the amount and kinds of usability and challenge problems, which can be found during initial and extended use of children's computer games. On the one hand the amount of problems might decrease over time, because users become more experienced. On the other hand, new errors may occur during extended use because users start making more errors related to increased carelessness. We discuss the chances of finding problems and relative importance of problems found during formative evaluations of initial and extended use of children's computer games.
