Distance perception in Virtual Environments 08

Distance Perception in Virtual Environments

引用

symposium on applied perception in graphics and visualization

作者： Williams, Betsy Johnson, Derek Shores, Lucy Narasimham, Gayathri Rhodes Coll Memphis TN 38112 USA Vanderbilt Univ Nashville TN 37235 USA

ISBN: (纸本)9781595939814

Virtual environments provide people with the opportunity to experience places and situations remote from their actual physical surroundings. However, we cannot expect spatial representation in virtual environments to be as accurate as spatial representation in physical environments. One reason for this is that perceived distance is systematically underestimated in virtual environments. The precise reasons for this are unknown. This work uses the bisection method shown in Bodenheimer et al. [2007] to study the perceived distance in virtual environments. In the virtual environment, distance bisection involves subjects adjusting an avatar using a joystick until they feel that the avatar bisects the distance between themselves and a target avatar. Bodenheimer et al. [2007] examine errors resulting from judging the bisection at 15m and 30m. We examine errors resulting from judging the bisection from five different distances: 3m, 7.5m, 15m, 22.5m, and 30m. We observe a linear relationship between the amount of foreshortening in judging the midpoint and distance. Additionally, perceiving a virtual representation of one's self in the virtual environment makes subjects significantly more accurate at judging the midpoint at 3m. However, for distances greater than 7.5m we find that asking people to use their virtual representation to judge the bisection leads to a significant increase in the amount of foreshortening.

symposium on applied perception in graphics and visualization

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

symposium on applied perception in graphics and visualization

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

Uncertainty constitutes a major obstacle to effective decision making. This work presents perceptual and cognitive principles from Tufte, Chambers and Bertin as well as results from user experiments for the theoretical evaluation of uncertainty visualization techniques that aid decision making. These principles can be used in future theoretical evaluations of existing or newly developed uncertainty visualization methods before usability testing with actual users. © 2007 ACM.

An experiment to determine factors that influence the perceived sex of virtual characters was conducted. Four different model types were used: highly realistic male and female models, an androgynous character, and a point light walker. Three different types of motion were applied to all models: motion captured male and female walks, and neutral synthetic walks. We found that both form and motion influence sex perception for these characters: for neutral synthetic motions, form determines perceived sex, whereas natural motion affects the perceived sex of both androgynous and realistic forms. These results have implications on variety and realism when simulating large crowds of virtual characters. © 2007 ACM.

Perception and prediction of simple object interactions

apgv 2007: 4th symposium on applied perception in graphics and visualization

作者： Nusseck, Manfred Lagarde, Julien Bardy, Benoit Fleming, Roland Bülthoff, Heinrich H. Max Planck Institute for Biological Cybernetics Tübingen University Montpellier-1

ISBN: (纸本)159593670X

For humans, it is useful to be able to visually detect an object's physical properties. One potentially important source of information is the way the object moves and interacts with other objects in the environment. Here, we use computer simulations of a virtual ball bouncing on a horizontal plane to study the correspondence between our ability to estimate the ball's elasticity and to predict its future path. Three experiments were conducted to address (1) perception of the ball's elasticity, (2) interaction with the ball, and (3) prediction of its trajectory. The results suggest that different strategies and information sources are used for passive perception versus actively predicting future behavior. © 2007 ACM.
