Abstract
The Collaborative-Research Augmented Immersive Virtual Environment
Laboratory at Rensselaer is a state-of-the-art space that
offers users the capabilities of multimodality and immersion. Realistic
and abstract sets of data can be explored in a variety of ways,
even in large group settings. This paper discusses the motivations
of the immersive experience and the advantages over smaller
scale and single-modality expressions of data. One experiment focuss
on the influence of immersion on perceptions of architectural
renderings. Its findings suggest disparities between participants’
judgment when viewing either two-dimensional printouts or the
immersive CRAIVE-Lab screen. The advantages of multimodality
are discussed in an experiment concerning abstract data exploration.
Various auditory cues for aiding in visual data extraction
were tested for their affects on participants’ speed and accuracy
of information extraction. Finally, artificially generated auralizations
are paired with recreations of realistic spaces to analyze the
influences of immersive visuals on the perceptions of sound fields.
One utilized method for creating these sound fields is a geometric
ray-tracing model, which calculates the auditory streams of each
individual loudspeaker in the lab to create a cohesive sound field
representation of the visual space.
