Abstract

Applying a User-centered Approach to Interactive Visualisation Design

“…Current bioinformatics tools do not meet the needs of the scientists. To help them perform their tasks, a new generation of tools and interactive visualisations has to be developed [38].…”

“…New generations of interactive visualisations not only have to meet user requirements but also have to enhance exploration of large heterogeneous data sets and provide domain-relevant insight into the data [38,66]. This raises challenges in evaluation of visualisations.…”

“…Innovative and complex designs need to be tested in order to check whether they meet user requirements. Existing evaluation methods are not fully applicable to new visualisation spaces and related advanced user interfaces [38]. Evaluation of any visualisation technique has to include an assessment of both visual representation and interaction styles [90].…”

“…Very few studies are devoted to frameworks for design and evaluation of information visualisation techniques [2,25,38,90]. Such models can help to perform evaluations in a structured way.…”

“…Koua and Kraak [38] developed a framework for the design and evaluation of exploratory geovisualisations for knowledge discovery. This study addresses the lack of evaluation methodologies and task specifications for user evaluations of geovisualizations.…”
