the proceedings contain 33 papers. the topics discussed include: statistical regularities in low and high dynamic range images;a reassessment of the simultaneous dynamic range of the human visual system;measuring the perception of light inconsistencies;evaluating effectiveness of illustrative visualization of schematic diagrams for maintenance tasks;analysis of disparity distortions in omnistereoscopic displays;how does presentation method and measurement protocol affect distance estimation in real and virtual environments?;egocentric distance judgments in a large screen display immersive virtual environment;can i pass?: using affordances to measure perceived size in virtual environments;a system for exploring large virtual environments that combines scaled translational gain and interventions;saliency for animated meshes with material properties;and perception of linear and nonlinear motion properties using a FACS validated 3D facial model.
We conducted four experiments on egocentric depthperception using blind walking with a restricted scanning method in boththe real and a virtual environment. Our viewing condition in all experiments was monocular. We...

In this work, different techniques for the generation of shadows and reflections have been compared in terms of the perceived quality by the final user. Results show that, for the analyzed scenarios, users do not present a clear preference for the images generated withthe more sophisticated techniques.

By uncertainty, we define an archaeological expert's level of confidence in an interpretation deriving from gathered evidence. Archaeologists and computer scientists have urged caution in the use of 3D for archaeological reconstructions because the availability of other possible hypotheses is not always being acknowledged. this poster presents a 3D visualization system of archaeological uncertainty.

Sequence comparison is a fundamental task in the biological sciences. Scientists often need to understand the similarities and differences between genetic sequences to understand evolution, to infer common function, or identify differences. Because the sequences are too long for manual examination, scientists rely on alignment tools that automatically identify subsequences that match between the sequences being compared. Numerous approaches for displaying and exploring alignments exist, and have been incorporated into a wide variety of tools. See [Procter et al. 2010] for a survey of several existing approaches.

Virtual Reality prototyping can be used early in a design process, in order to question observers about the aesthetics of future vehicles, without the need for physical mock-ups. However, it is suspected that numerical display formats and solutions are not all equivalent, concerning the physical dimensions an observer is able to appreciate. this question is particularly acute, if one considers the transferability of conclusions reached using virtual prototyping to the real outcome of the design process.

this paper introduces a solution for enhancing depthperception in a given 3D computer-generated scene. For this purpose, we propose a framework that decides on the suitable depth cues for a given scene and the rendering methods which provide these cues. First, the system calculates the importance of each depth cue using a fuzzy logic based algorithm which considers the target tasks in the application and the spatial layout of the scene. then, a knapsack model is constructed to keep the balance between the rendering costs of the graphical methods that provide these cues and their contibution to depthperception. this cost-profit analysis step selects the proper rendering methods. In this work, we also present several objective and subjective experiments which show that our automated depth enhancement system is statistically (p
In this paper we explore the ability of the human visual system to detect inconsistencies in the illumination of objects in images. We specifically focus on objects being lit from different angles as the rest of the i...
