Promoting Eco-driving through Persuasive Visualization

The goal of sustainability is to preserve resources for future generations. Climate change is a major environmental problem that violates the goal of sustainability. A key strategy to combat climate change is to reduce carbon emission that is largely generated by road transport. Traditional interventions on promoting eco-driving behaviors often fail to convince people to alter their driving behaviors. The growing use of persuasive visualization allows individuals to become aware of the relationship between their driving behaviors and the associated environmental impact. Drawing on the expectancy theory of motivation, this study plans to explore ways to design effective visualization to promote eco-driving behaviors. Additionally, this study proposes a unique lab experiment that enables the manipulation of visualizations and presents an opportunity to observe individuals’ driving behavioral changes

Using Data Visualisation to tell Stories about Collections

The paper explores visualisation of “big data” from digitised museum collections and archives, focusing on the relationship between data, visualisation and narrative. A contrast is presented between visualisations that show “just the data” and those that present the information in such a way as to tell a story using visual rhetorical devices; such devices have historically included trees, streams, chains, geometric shapes and other forms. The contrast is explored through historical examples and a survey of current practice. A discussion centred on visualising datasets from the British Library, Science Museum and Wellcome Library is used to outline key research questions

Towards a Flexible User-Centred Visual Presentation Approach

Leveraging the power of flexible visual presentations has become an effective way to aid information interpretation, decision making and problem solving. It is indispensable to address the high complexities with visualization problems and relieve the impact from the intrinsic limitations of human cognitive capacity. Addressing these problems raises demanding requirements for information presentation flexibility. However, many existing visualization systems tend to provide weak support for such flexibility due to the issue of closely coupled information representation and presentation in system designs. This issue limits their support for rich presentation options, flexible presentation integration and reusability, and vivid storytelling of data. To help with addressing these problems, issues and requirements, this paper generalizes typical presentation models to provide paradigm level support for achieving presentation flexibility, and identifies key requirements for presentation development to accomplish the flexibility at a system level. With articulating the requirements at both paradigm and system levels, the paper proposes a user-centred process to realize presentation flexibility by meeting both functional and cognitive requirements for information presentation. The proposed theory is validated against a real-world business case and applied to guide the development of a prototypical system, which is demonstrated through a sequence of scenario-driven illustrations
