Large-scale molecular dynamics (MD) simulations are some of the primary applications running on today's supercomputers. These simulations frequently compute the interactions of millions of atoms over millions of time steps, and petascale simulations will target billion atom simulations in the near future. Visualizing the state of such large-scale simulations poses a significant challenge for both data reduction and perception. Standard tools for 3D visualization of MD simulations - such as direct visualization ofthe molecules in their simulated physical arrangement - eventually grow so dense (with more atoms than screen pixels) that only thevolumetric shape of the simulation domain is apparent, rather than its detailed content. In this paper, we describe a method for visualizing simulations of a compound in bulk which we refer to as the ensemble display. An ensemble display is produced by superimposing molecular neighborhoods onto fixed reference molecules. This results in a 3D visualization which preserves inter-molecular distances andangles between pairs of molecules while greatly reducing the visual complexity. We performed human-subjects experiments to test the hypothesis that subjects could deduce a bulk physical property of the simulation (temperature) from the ensemble display more accurately than from other common visualizations of MD simulation. Our results show that temperature estimates under the ensemble display had the least error of the tested visualization techniques. © 2008 acm.

The analysis of scientific articles produced by different groups of authors helps to identify and characterize research groups and collaborations among them. Although this is it quite studied area, some issues, such as quick understanding Of groups and visualization of large social networks still pose some interesting challenges. In order to contribute to this study, we present a solution based in Overlapper, a tool for the visualization of overlapping groups that makes use of all enhanced variation of force-directed graphs. For a real case Study, the tool has been applied to articles in the DBLP database.

As the use of virtual and augmented reality applications becomes more common, the need to fully understand how observers perceive spatial relationships grows more critical. One of the key requirements in engineering a practical virtual or augmented reality system is accurately conveying depth and layout. This requirement has frequently been assessed by measuring judgments of egocentric depth. These assessments have shown that observers in virtual reality (VR) perceive virtual space as compressed relative to the real world, resulting in systematic underestimations of egocentric depth. Previous work has indicated that similar effects may be present in augmented reality (AR) as well. This paper reports an experiment that directly measured egocentric depth perception in both VR and AR conditions;it is believed to be the first experiment to directly compare these conditions in the same experimental framework. In addition to VR and AR, two control conditions were studied: viewing real-world objects, and viewing real-world objects through a head-mounted display. Finally, the presence and absence of motion parallax was crossed with all conditions. Like many previous studies, this one found that depth perception was underestimated in VR, although the magnitude of the effect was surprisingly low. The most interesting finding was that no underestimation was observed in AR. © 2008 acm.

3d shape and scene layout are often misperceived when viewing stereoscopic displays. For example, viewing from the wrong distance alters an object's perceived size and shape. It is crucial to understand the causes of such misperceptions so one can determine the best approaches for minimizing them. The standard model of misperception is geometric. The retinal images are calculated by projecting from the stereo images to the viewer's eyes. Rays are back-projected from corresponding retinal-image points into space and the ray intersections are determined. The intersections yield the coordinates of the predicted percept. We develop the mathematics of this model. In many cases its predictions are close to what viewers perceive. There are three important cases, however, in which the model fails: 1) when the viewer's head is rotated about a vertical axis relative to the stereo display (yaw rotation);2) when the head is rotated about a forward axis (roll rotation);3) when there is a mismatch between the camera convergence and the way in which the stereo images are displayed. In these cases, most rays from corresponding retinal-image points do not intersect, so the standard model cannot provide an estimate for the 3d percept. Nonetheless, viewers in these situations have coherent 3d percepts, so the visual system must use another method to estimate 3d structure. We show that the non-intersecting rays generate vertical disparities in the retinal images that do not arise otherwise. Findings in vision science show that such disparities are crucial signals in the visual system's interpretation of stereo images. We show that a model that incorporates vertical disparities predicts the percepts associated with improper viewing of stereoscopic displays. Improving the model of misperceptions will aid the design and presentation of 3d displays.

Sensitivity to Scene Motion for Phases of Head Yaws 08

Sensitivity to Scene Motion for Phases of Head Yaws

In order to better understand how scene motion is perceived in immersive virtual environments and to provide guidelines for designing more useable systems, we measured sensitivity to scene motion for different phases of quasi-sinusoidal head yaw motions. We measured and compared scene-velocity thresholds for nine subjects across three conditions: visible With head rotation (W) where the scene is presented during the center part of sinusoidal head yaws and the scene moves in the same direction the head is rotating, visible Against head rotation (A) where the scene is presented during the center part of sinusoidal head yaws and the scene moves in the opposite direction the head is rotating, and visible at the Edge of head rotation (E) where the scene is presented at the extreme of sinusoidal head yaws and the scene moves during the time that head direction changes. The W condition had a significantly higher threshold (decreased sensitivity) than both the E and A conditions. The median threshold for the W condition was 2.1 times the A condition and 1.5 times the E condition. We did not find a significant difference between the E and A conditions, although there was a trend for the A thresholds to be less than the E thresholds. An Equivalence Test showed the A and E thresholds to be statistically equivalent. Our results suggest the phase of user's head yaw should be taken into account when inserting additional scene motion into immersive virtual environments if one does not want users to perceive that motion. In particular, there is much more latitude for artificially and imperceptibly rotating a scene, as in Razzaque's redirecting walking technique, in the same direction of head yaw than against the direction of yaw. The implications for maximum end-to-end latency in a head-mounted display is that users are less likely to notice latency when beginning a head yaw (when the scene moves with the head) than when slowing down a head yaw (when the scene moves against the hea

Redirected walking allows users to walk through large-scale immersive virtual environments (IVEs) while physically remaining in a reasonably small workspace by intentionally injecting scene motion into the IVE. In a constant stimuli experiment with a twoalternative-forced-choice task we have quantified how much humans can unknowingly be redirected on virtual paths which are different from the paths they actually walk. 18 subjects have been tested in four different experiments: (E1a) discrimination between virtual and physical rotation, (E1b) discrimination between two successive rotations, (E2) discrimination between virtual and physical translation, and discrimination of walking direction (E3a) without and (E3b) with start-up. In experiment E1a subjects performed rotations to which different gains have been applied, and then had to choose whether or not the visually perceived rotation was greater than the physical rotation. In experiment E1b subjects discriminated between two successive rotations where different gains have been applied to the physical rotation. In experiment E2 subjects chose if they thought that the physical walk was longer than the visually perceived scaled travel distance. In experiment E3a subjects walked a straight path in the IVE which was physically bent to the left or to the right, and they estimate the direction of the curvature. In experiment E3a the gain was applied immediately, whereas the gain was applied after a start-up of two meters in experiment E3b. Our results show that users can be turned physically about 68% more or 10% less than the perceived virtual rotation, distances can be up-or down-scaled by 22%, and users can be redirected on an circular arc with a radius greater than 24 meters while they believe they are walking straight.
