This paper presents an initial investigation into the use of Tactons, or tactile icons, to present progress information in desktop human-computer interfaces. Progress bars are very common in a wide range of interfaces but have problems. For example, they must compete for screen space and visual attention with other visual tasks such as document editing or web browsing. To address these problems...

Recent advances in web-enabled graphics technologies have the potential to make a dramatic impact on developing highly interactive Geovisual Analytics applications for the Internet. An emerging and challenging application domain is geovisualization of regional (sub-national) statistics. Higher integration driven by institutional processes and economic globalisation is eroding national borders a...

User and behavioral modeling plays a critical role in a variety of online services such as web search, advertising, ecommerce, and news recommendation.

I nnovation in the technical means of empirical inquiry is a necessary and perhaps inevitable component of scientific progress. New tools not only allow investigators to study phenomena that had previously been inaccessible to them, but also permit them to look at existing phenomena in novel ways, and occasionally provide metaphors that serve as building blocks of original theory. 2 Yet technic...
