Tooling user studies tasks is fundamental to reduce the burden of practitioners, facilitators, and observers during user interface (UI) evaluations.
However, available tools for collecting detailed data (i.e., beyond clicks streams) are paid or have a complex setup.
In this context, User Test Logger is proposed as a general-purpose web browser plugin for Firefox to be used in local user studies.
It provides detailed data logging, log download, and reporting features.
The tool is freely available so that Human-Computer Interaction (HCI) practitioners can use it as a core tool for empirical evaluations or additional data source in mixed methods evaluations, as done in (Santos and Santana, 2019) when we combined interaction logs with eye gaze data.
Reports include: usage graph, heat map representing mouse fixations (as an analogy to eye fixations), mouse plot, usage graph patterns (in a tabular accessible format), and incidents from the usage graph (also in a tabular format).
User Test Logger is installed inside web browser, easing the setup.
With User Test Logger it is possible to record all detailed user interaction events triggered inside the web browser, including all of its tabs.
When a user test session is concluded, it is just stop recording events and download the interaction log. In a matter of seconds, the practitioner can download interaction logs and start the analysis.
