In standard computer graphics environments, there are numerous of tools to view and edit data. Those tools often use more than one view to support visualization and interaction more efficiently [Maple et al. 2004]. Based on existing work of Coordinated Multiple Views (CMV) [Roberts 2007], our approach introduces atomic modifiers to coordinate views in 3D-applications. Adaptable to a given context, complex and flexible view adjustments can be achieved by combining modifiers. Thereby, users gain a deeper and better understanding of the visualized data.

We conducted a followup experiment to the work of Lin et al. [2011]. The experimental protocol was the same as that of Experiment Four in Lin et al. [2011] except the viewing condition was binocular instead of monocular. In that work there was no distance underestimation, as has been widely reported elsewhere, and we were motivated in this experiment to see if stereoscopic effects in head-mounted displays (HMDs) accounted for this effect.

Whenever we move, we gain experience with how changes in visual flow are related to movement through the environment. One way that researchers have studied these perception-action linkages is through perturbing the normal relationship between perception and action [Kunz et al. 2009;Rieser et al. 1995]. In these studies, people experience an optic flow rate that is manipulated to be significantly faster or slower than their walking rate. Comparison of distance estimates from before and after this recalibration experience typically shows that people who experience faster optic flow undershoot targets at posttest and people who experience slower optic flow overshoot targets at posttest. Here, we examined how experience with mismatched perception and action (i.e., faster or slower optic flow) in a virtual environment affects subsequent distance estimation in the same virtual environment and in a similar real environment. Of particular interest was whether perception-action coupling is more malleable in the virtual environment than in the real environment.

In the last decade, there has been a rapidly growing development of low-cost and commercial interactive systems, both for professional (e.g. scientific visualization, surgery, rehabilitation), and consumer applications (e.g. 3D cinema and videogames). Moreover, there is a recent interest towards the development of simple and affordable systems for motor and cognitive rehabilitation applications to allow patients to perform psychomotor rehabilitation exercises without having to leave their homes [Attygalle et al. 2008].
We present a new method to visualize uncertain scalar data fields by combining color scale visualization techniques with animated, perceptually adapted Perlin noise. The parameters of the Perlin noise are controlled b...
