~nviron~~n~ for Visualization and Sonification of Br tivr

rogress and availability of multimedia and virtual reality (VR) technology make possible a new treiid of perceptual data presentation. As computer performance increases, the major bottleneck could be the human-computer interface. The bandwidth of this interface will be bound by characteristics of human perception, and hence the quest for a new presentation paradigm has commenced in different scientific fields. Techniques developed in VR facilitate multiple data-stream presentation and navigation through huge data sets. New iminersive environments are particularly appropriate to improve insight into complex biomedical phenomena, which are naturally multidimensional. As an extension to visualization, which gives predominantly spatial distribution, acoustic rendering may improve temporal cues. The technique of data presentation using variable sound features is called sonification [ 1-41. In this article, we present early efforts toward
