Abstract:
Effective visual representation is related to how people interpret signs created to carry specific information. In the last years many user interface evaluation tools are considering detailed usage data to represent users’ actions. The volume of data gathered is leading developers to represent usage in a summarized way through graphical representations. If visual components used to represent complex data are not effective, then graphics used to summarize data may turn the interpretation of complex terms even harder. This work presents a study about graphical representations for user interface (UI) events and contributes with the validation of usage graph visualization and an open set of signs to support the summarization of client-side logs. The study involved 28 Information Technology specialists, potential users of UI evaluation tools. From the results one expects that evaluation tool developers, evaluators, and Web usage miners can reuse the validated usage graph representation an
d proposed set of signs to represent usage data in a summarized way.
