In this study we examined this assumption by testing to what degree graphical fidelity was associated with physiological arousal as measured by a galvanic skin response (GSR) sensor. Thirty-six subjects played two different video games at the highest and lowest graphical quality settings while their GSR activity was measured. No significant difference in GSR was observed that was associated with graphical quality. We conclude that, for applications in which an emotional response is desired, increased graphical quality alone does not predict a physiological arousal response.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

We suspect that a small number of steering strategies are sufficient for generating typical pedestrian behaviors observed in daily-life situations. Through these limited strategies we show that complex steering behaviors are generated by executing appropriate steering strategies at the appropriate time. In our model, decisions on the selection, scheduling and execution of steering strategies in a given situation are based on the matching results between the currently perceived spatial-temporal patterns and the prototypical cases in an agent's experience base. From a modeler's point of view, our approach is intuitive to use. Our model is carefully evaluated through a three-stage validation process, using experimental studies on basic test scenarios, model comparisons under standard but more complex test scenarios, and sensitivity analysis on key model parameters. Experimental results show that our model is able to generate results that reflect the collective efficiency of crowd dynamics and is in agreement with existing literature on pedestrian studies.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

This question takes importance in lots of fields, such as fluid mechanics, where space and time resolved dataset become more and more common. For that reason, we present an interaction design study of an window exploration metaphor, for large 3D virtual environment. The metaphor is based on the use of a tablet as a tangible and movable window on a virtual environment. Rotations in the environment are tracker-less mapped on the rotations of the tablet. Our design is inspired by fluid mechanics issues, but is build keeping generalizability in mind. The study shows that mapping three degrees of freedom onto corresponding real three degrees of freedom of space raises the transparency, the efficiency of data exploration and the space awareness of users.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

A faceton is given as an oriented point floating in the air and defines a plane of infinite extent passing through the point. The polygonal mesh model is constructed by taking the intersection of the planes associated with the facetons. With the simple drag-and-drop and group interaction of faceton, users can easily create 3D architecture models in the VE. The faceton primitive and its interaction reduce the overhead associated with standard polygonal mesh modeling in VE, where users have to manually specify vertexes and edges which could be far away. The faceton representation is inspired by the research on boundary representations (B-rep) and constructive solid geometry (CSG), but it is driven by a novel adaptive bounding algorithm and is specifically designed for the 3D modeling activities in an immersive virtual environment.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

Color blending negatively affects the usability of such displays as it impacts the legibility and color encodings of digital content. Color correction aims at reducing the impact of color blending by finding an alternative display color which, once mixed with the background, results in the color originally intended.\u0000 In this paper we model color blending based on two distortions induced by the optical see-through display. The render distortion explains how the display renders colors. The material distortion explains how background colors are changed by the display material. We show the render distortion has a higher impact on color blending and propose binned-profiles (BP) - descriptors of how a display renders colors - to address it. Results show that color blending predictions using BP have a low error rate - within nine just noticeable differences (JND) in the worst case. We introduce a color correction algorithm based on predictions using BP and measure its correction capacity. Results show light display colors can be better corrected for all backgrounds. For high intensity backgrounds light colors in the neutral and CyanBlue regions perform better. Finally, we elaborate on the applicability, design and hardware implications of our approach.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

Analogously, the task itself also imposes different levels of cognitive load. It is common sense in 3D user interfaces research that a higher number of degrees of freedom increases the interface cognitive load. If the cognitive load is significant, it might compromise the user performance and undermine the evaluation of user skills in a virtual environment. In this paper, we propose an assessment of two immersive VR interfaces with varying degrees of freedom in two VR tasks: risk perception and basic object selection. We examine the effectiveness of both interfaces in these two different tasks. Results show that the number of degrees of freedom does not significantly affect a basic selection task, but it affects risk perception task in an unexpected way.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

These systems often suffer from lower frame rates due to network bandwidth limitations, implementation of the intercept routine, and in some cases, the intercepted application's frame rate. To mitigate these issues and to enhance intercept-based systems in other ways, we present intercept tags, which are OpenGL geometries that are interpreted instead of rendered. We have identified and developed several uses for intercept tags, including hand-off interactions, display techniques, and visual enhancements. To demonstrate the value of intercept tags, we conducted a user study to compare a simple virtual hand technique implemented with and without intercept tags. Our results show that intercept tags significantly improve user performance and experience.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

In this paper we propose solutions for simulation in virtual environments a few basic arthroscopic procedures including incision of the arthroscopic camera, positioning of the instrument in front of it, as well as using scissors and graspers.
