Direct-touch interaction is receiving an increasing amount of attention in the HCI domain and has recently been applied to some problems in information visualization. However, the field of scientific visualization has not seen much work on how direct-touch interaction could benefit the interactive visualization process. One reason may be that scientific visualization typically deals with datase...

In this work, a simple semi-empirical model is proposed, based on Response Surface Model, RSM, to determine the shape of an attached oblique shock wave emanating from a pointed axisymmetric nose at zero angle of attack. Extensive supersonic visualization images have been compiled from various nose shapes at different Mach numbers, along with some others performed by the author for the present p...

We present an empirical study investigating collaborative and individual decision-making about data using two different information visualization systems. Based on previous research, one system is considered more transparent than the other in terms of visual representation and functionality. We found that people who worked in groups were more correct in their answers for objective questions, ba...

Useful techniques for information visualization allow engineers or analysts to produce works of art. A work entitled “Financial Reminiscences” is an example of such works. This work has been produced using a visualization technique for financial analysis. This technique is not only a tool for generating images. It is closely related to the information visualized in the work. Thus, the audience ...

Traditionally, evaluation studies in information visualization have measured effectiveness by assessing performance time and accuracy. More recently, there has been a concerted effort to understand aspects beyond time and errors. In this paper we study enjoyment, which, while arguably not the primary goal of visualization, has been shown to impact performance and memorability. Different models ...

Speculative design is an emerging rhetorical strategy in design practices and research to raise public awareness in social agendas that have been little explored. As a stream of this type of research, we propose speculative visualization that aims to achieve speculative design by utilizing techniques from data visualization and graphic design. Specifically, speculative visualization represents ...

We analyze the Austrian social insurance system, focusing on the labor market as well as the pension system, on behalf of governmental institutions and other official stake holders. Visualizations play an increasingly important role. We present two examples from current projects – a very simply static one and a more complex interactive one – that both demonstrate the benefits of visualizations ...

purpose: to investigate demographic, clinical and histopathologic features of consecutive exotropia. methods: patients with consecutive exotropia who underwent surgery in farabi hospital between september 2014 and april 2015 were enrolled in this study. after complete ophthalmologic examination and far and near deviation measurement, all patients with negative forced duction test underwent 4-mm...
