Bimodal perception of audio-visual material properties for virtual environments
Nicolas Bonneel, Clara Suied, Isabelle Viaud-Delmon, George Drettakis
Article No.: 1
DOI: 10.1145/1658349.1658350

High-quality rendering of both audio and visual material properties is very important in interactive virtual environments, since convincingly rendered materials increase realism and the sense of immersion. We studied how the level of detail of...

Differences in head orientation behavior for speakers and listeners: An experiment in a virtual environment
Rutger Rienks, Ronald Poppe, Dirk Heylen
Article No.: 2
DOI: 10.1145/1658349.1658351

An experiment was conducted to investigate whether human observers use knowledge of the differences in focus of attention in multiparty interaction to identify the speaker amongst the meeting participants. A virtual environment was used to have...

Spatial learning and navigation using a virtual verbal display
Nicholas A. Giudice, Jonathan Z. Bakdash, Gordon E. Legge, Rudrava Roy
Article No.: 3
DOI: 10.1145/1658349.1658352

We report on three experiments that investigate the efficacy of a new type of interface called a virtual verbal display (VVD) for nonvisual learning and navigation of virtual environments (VEs). Although verbal information has been studied for...

Volume composition and evaluation using eye-tracking data
Aidong Lu, Ross Maciejewski, David S. Ebert
Article No.: 4
DOI: 10.1145/1658349.1658353

This article presents a method for automating rendering parameter selection to simplify tedious user interaction and improve the usability of visualization systems. Our approach acquires the important/interesting regions of a dataset through...

Simulating believable forward accelerations on a stewart motion platform
Daniel R. Berger, Jörg Schulte-Pelkum, Heinrich H. Bülthoff
Article No.: 5
DOI: 10.1145/1658349.1658354

It is still an unsolved problem how to optimally simulate self-motion using motion simulators. We investigated how a forward acceleration can be simulated as believably as possible on a hexapod motion platform equipped with a projection...

Computational visual attention systems and their cognitive foundations: A survey
Simone Frintrop, Erich Rome, Henrik I. Christensen
Article No.: 6
DOI: 10.1145/1658349.1658355

Based on concepts of the human visual system, computational visual attention systems aim to detect regions of interest in images. Psychologists, neurobiologists, and computer scientists have investigated visual attention thoroughly during the last...

Multidimensional scaling analysis of haptic exploratory procedures
Theresa Cooke, Christian Wallraven, Heinrich H. Bülthoff
Article No.: 7
DOI: 10.1145/1658349.1658356

Previous work in real and virtual settings has shown that the way in which we interact with objects plays a fundamental role in the way we perceive them. This article uses multidimensional scaling (MDS) analysis to further characterize and...
