Redirected walking to explore virtual environments: Assessing the potential for spatial interference
Eric Hodgson, Eric Bachmann, David Waller
Article No.: 22
Redirected walking has gained popularity in recent years as a way of enhancing the safety of users immersed in a virtual reality simulation and of extending the amount of space that can be simulated in a virtual environment (VE). Limits imposed by...
Attentional gradient for crossmodal proximal-distal tactile cueing of visual spatial attention
Roslizawaty Mohd Rosli, Hong Z. Tan, Robert W. Proctor, Rob Gray
Article No.: 23
Past studies have established a crossmodal spatial attentional link among vision, audition, and touch. The present study examined the dependence of visual attention on the distance between a distal visual target (a changing element among static...
Bimodal task-facilitation in a virtual traffic scenario through spatialized sound rendering
Matthias Bernhard, Karl Grosse, Michael Wimmer
Article No.: 24
Audio rendering is generally used to increase the realism of virtual environments (VE). In addition, audio rendering may also improve the performance in specific tasks carried out in interactive applications such as games or simulators. In this...
CyberWalk: Enabling unconstrained omnidirectional walking through virtual environments
J. L. Souman, P. Robuffo Giordano, M. Schwaiger, I. Frissen, T. Thümmel, H. Ulbrich, A. De Luca, H. H. Bülthoff, M. O. Ernst
Article No.: 25
Despite many recent developments in virtual reality, an effective locomotion interface which allows for normal walking through large virtual environments was until recently still lacking. Here, we describe the new CyberWalk omnidirectional...
Effects of scale change on distance perception in virtual environments
Tien Dat Nguyen, Christine J. Ziemer, Timofey Grechkin, Benjamin Chihak, Jodie M. Plumert, James F. Cremer, Joseph K. Kearney
Article No.: 26
We conducted a series of experiments to investigate effects of scale changes on distance perception in virtual environments. All experiments were carried out in an HMD. Participants first made distance estimates with feedback in a virtual tunnel...
Modeling human aesthetic perception of visual textures
Stefan Thumfart, Richard H. A. H. Jacobs, Edwin Lughofer, Christian Eitzinger, Frans W. Cornelissen, Werner Groissboeck, Roland Richter
Article No.: 27
Texture is extensively used in areas such as product design and architecture to convey specific aesthetic information. Using the results of a psychological experiment, we model the relationship between computational texture features and aesthetic...
Integrating multiple views with virtual mirrors to facilitate scene understanding
Carmen E. Au, James J. Clark
Article No.: 28
In this article, an image integration technique called Virtual Mirroring (VM) is evaluated. VM is a technique that combines multiple 2D views of a 3D scene into a single composite image by overlaying views onto virtual mirrors. Given multiple...
