Moving sounds enhance the visually-induced self-motion illusion (circular vection) in virtual reality
Bernhard E. Riecke, Aleksander Väljamäe, Jörg Schulte-Pelkum
Article No.: 7
DOI: 10.1145/1498700.1498701

While rotating visual and auditory stimuli have long been known to elicit self-motion illusions (“circular vection”), audiovisual interactions have hardly been investigated. Here, two experiments investigated whether visually induced...

The effects of head-mounted display mechanical properties and field of view on distance judgments in virtual environments
Peter Willemsen, Mark B. Colton, Sarah H. Creem-Regehr, William B. Thompson
Article No.: 8
DOI: 10.1145/1498700.1498702

Research has shown that people are able to judge distances accurately in full-cue, real-world environments using visually directed actions. However, in virtual environments viewed with head-mounted display (HMD) systems, there is evidence that...

On spatiochromatic visual sensitivity and peripheral color LOD management
Andrew T. Duchowski, David Bate, Paris Stringfellow, Kaveri Thakur, Brian J. Melloy, Anand K. Gramopadhye
Article No.: 9
DOI: 10.1145/1498700.1498703

Empirical findings from a gaze-contingent color degradation study report the effects of artificial reduction of the human visual system's sensitivity to peripheral chromaticity on visual search performance. To our knowledge, this is the first such...

Toward a definition of visual complexity as an implicit measure of cognitive load
Simon Harper, Eleni Michailidou, Robert Stevens
Article No.: 10
DOI: 10.1145/1498700.1498704

The visual complexity of Web pages is much talked about; “complex Web pages are difficult to use,” but often regarded as a subjective decision by the user. This subjective decision is of limited use if we wish to understand the...

Real-world vision: Selective perception and task
Roxanne L. Canosa
Article No.: 11
DOI: 10.1145/1498700.1498705

Visual perception is an inherently selective process. To understand when and why a particular region of a scene is selected, it is imperative to observe and describe the eye movements of individuals as they go about performing specific tasks. In...
