Empirical data on the usability of eyenalyzer

How did the data collection work?The goal of the study is to get insights to the usability of the data analysis tool eyenalyzer. Hence the participants complete 6 data analysis tasks using eyenalyzer, while their eye movements are recorded by eye tracking. Note that the tasks are the same as in this conference paper and the corresponding data repository, but are broken down into 13 sub-tasks; each task targets one action page in eyenalyzer. After each task, the participants rate the difficulty of the task (on a 7-point Likert scale); after completing all tasks, they fill out a questionnaire on their demographic data as well as the two validated questionnaires System Usability Scale (SUS) and User Experience Questionnaire (UEQ). The submitted solutions are later checked for correctness; the answers to SUS and UEQ are transformed into scores. The manual rewatching of the eye tracking recordings gives the navgiation methods applied for switchting between the tasks or action pages of eyenalyzer as well as the handling of dialog boxes and info fields (i.e. to what extent they are read and whether or not the trigger a positive reaction or not). Further details on the procedure will be found in a soon to be published conference paper.
