You can't always sketch what you want: Understanding Sensemaking in Visual Query Systems
Visual query systems (VQSs) empower users to interactively search for line
charts with desired visual patterns, typically specified using intuitive
sketch-based interfaces. Despite decades of past work on VQSs, these efforts
have not translated to adoption in practice, possibly because VQSs are largely
evaluated in unrealistic lab-based settings. To remedy this gap in adoption, we
collaborated with experts from three diverse domains---astronomy, genetics, and
material science---via a year-long user-centered design process to develop a
VQS that supports their workflow and analytical needs, and evaluate how VQSs
can be used in practice. Our study results reveal that ad-hoc sketch-only
querying is not as commonly used as prior work suggests, since analysts are
often unable to precisely express their patterns of interest. In addition, we
characterize three essential sensemaking processes supported by our enhanced
VQS. We discover that participants employ all three processes, but in different
proportions, depending on the analytical needs in each domain. Our findings
suggest that all three sensemaking processes must be integrated in order to
make future VQSs useful for a wide range of analytical inquiries.Comment: Accepted for presentation at IEEE VAST 2019, to be held October 20-25

Sticks, balls or a ribbon? Results of a formative user study with bioinformaticians
User interfaces in modern bioinformatics tools are designed for experts. They are too complicated for\ud
novice users such as bench biologists. This report presents the full results of a formative user study as part of a\ud
domain and requirements analysis to enhance user interfaces and collaborative environments for\ud
multidisciplinary teamwork. Contextual field observations, questionnaires and interviews with bioinformatics\ud
researchers of different levels of expertise and various backgrounds were performed in order to gain insight into\ud
their needs and working practices. The analysed results are presented as a user profile description and user\ud
requirements for designing user interfaces that support the collaboration of multidisciplinary research teams in\ud
scientific collaborative environments. Although the number of participants limits the generalisability of the\ud
findings, the combination of recurrent observations with other user analysis techniques in real-life settings\ud
makes the contribution of this user study novel
A comparison of linear and calendar travel itinerary visualizations for personal digital assistants
Various graphical travel itinerary visualization systems have in recent years been developed to allow making easier references between different events such as flights and hotel bookings on a travel itinerary, thereby addressing a problem with tabular itineraries which list travel events in a chronological order of date and time, and only allow referencing consecutive events. These graphical travel itinerary systems are based on a linear visualization of travel events. Although this linear visualization deals with some of the problems associated with tabular itineraries, it is not the only form of visualization which might be capable of addressing these issues. This paper introduces a new visualization of travel itineraries, called the calendar visualization, which relies on a more familiar concept of calendars to depict the relationships between travel events. This paper also describes an empirical study undertaken to compare the calendar and linear itinerary visualizations
Reflective visualization and verbalization of unconscious preference
A new method is presented, that can help a person become aware of his or her
unconscious preferences, and convey them to others in the form of verbal
explanation. The method combines the concepts of reflection, visualization, and
verbalization. The method was tested in an experiment where the unconscious
preferences of the subjects for various artworks were investigated. In the
experiment, two lessons were learned. The first is that it helps the subjects
become aware of their unconscious preferences to verbalize weak preferences as
compared with strong preferences through discussion over preference diagrams.
The second is that it is effective to introduce an adjustable factor into
visualization to adapt to the differences in the subjects and to foster their
mutual understanding.Comment: This will be submitted to KES Journa
