“…Some research works provided different solutions to drive evaluators in finding usability issues. For example, in [26] the user's actions during a task and the optimal actions to perform a task are shown on a timeline, in order to help the evaluator to see the user's actions and the deviations from the correct ones, speeding up the time to investigate something that occurred at a certain time. Similarly, WUP is a tool for remote usability evaluation of websites supporting evaluators in carrying out a visual comparison between actual user behaviour and an optimal sequence of actions visualized on an interactive timeline [27].…”

Daily experiences in working with various types of computer systems show that, despite the offered functionalities, users have many difficulties, which affect their overall User eXperience (UX). The UX focus is on aesthetics, emotions and social involvement, but usability has a great influence on UX. Usability evaluation is acknowledged as a fundamental activity of the entire development process in software practices. Research in Human-Computer Interaction has proposed methods and tools to support usability evaluation. However, when performing an evaluation study, novice evaluators still have difficulties to identify usability problems and to understand their causes: they would need easier to use and possibly automated tools. This article describes four visualization techniques whose aim is to support the work of evaluators when performing usability tests to evaluate websites. Specifically, they help detect ''usability smells'', i.e. hints on web pages that might present usability problems, by visualizing the paths followed by the test participants when navigating in a website to perform a test task. A user study with 15 participants compared the four techniques and revealed that the proposed visualizations have the potential to be valuable tools for novice usability evaluators. These first results should push researchers towards the development of further tools that are capable to support the detection of other types of UX smells in the evaluation of computer systems and that can be translated into common industry practices. INDEX TERMS User interfaces, website evaluation, design for quality, user eXperience, usability.

“…The recreation of particular Web interaction recordings of individual users allows developers to find hard to replicate behaviours (Burg et al, 2013). When the task being performed is known, visualisations of finer grained interaction, such as mouse clicks, enable comparisons between various user sessions (Rzeszotarski and Kittur, 2012;Breslav et al, 2014;Paternó et al, 2016).…”

When the hypotheses about users' behaviour on interactive systems are unknown or weak, mining user interaction logs in a data-driven fashion can provide valuable insights. Yet, this process is full of challenges that prevent broader adoption of data-driven methods. We address these pitfalls by assisting user researchers in customising event sets, filtering the noisy outputs of the algorithms and providing tools for analysing such outputs in an exploratory fashion. This tooling facilitates the agile testing and refinement of the formulated hypotheses of use. A user study with twenty participants indicates that compared to the baseline approach, assisted pattern mining is perceived to be more useful and produces more actionable insights, despite being more difficult to learn.

“…WUP uses sophisticated visualizations to show event log data: a timeline comparator allowing the interactive manipulation of timelines to find deviations with the optimal one and displaying color-coded events and associated data; a page-flow comparator or storyboard, and even screen dumps. In a more recent work, the authors have presented an improved, more interactive tool for timeline comparison (Paternò et al 2016). The difference with our approach is that it works with a specific evaluation task list and the definition of an optimal path for each task.…”

Usability assessment of web applications continues to be an expensive and often neglected practice. While large companies are able to spare resources for studying and improving usability in their products, smaller businesses often divert theirs in other aspects. To help these cases, researches have devised automatic approaches for user interaction analysis, and there are commercial services that offer automated usability statistics at relatively low fees. However, most existing approaches still fall short in specifying the usability problems concretely enough to identify and suggest solutions. In this work we describe usability smells of user interaction, i.e., hints of usability problems on running web applications, and the process in which they can be identified by analyzing user interaction events. We also describe USF, the tool that implements the process in a fully automated way with minimum setup effort. USF analyses user interaction events on-the-fly, discovers usability smells and reports them together with a concrete solution in terms of a usability refactoring, providing usability advice for deployed web applications.
