VR/Multimedia Synthesis, Phase II

Authors: Helene M. Hoffman; CALIFORNIA UNIV SAN DIEGO LA JOLLA

Abstract:

The University of California, San Diego (UCSD) School of Medicine's (SOM) Learning Resources Center (LRC) is developing a virtual world to provide a compelling learning environment and a valuable paradigm for navigating through medical knowledge. It combines 3-D anatomic models (based on the Visible Human dataset) with supporting 2-D media (e.g., diagnostic imagery, surgical videos, etc.) to establish a dynamic learning environment that integrates spatial knowledge (VR) with extant multimedia (MM) resources. Case based scenarios promote exploration, discovery, and active learning by enabling users to dissect 3-D anatomic models while accessing supporting resource elements. Exercises are organized in a 3-D Study Guide that supplies: (1) an interactive Table of Contents for flexible non-sequential access to the case material; (2) descriptive text which provides an organized presentation of key concepts; and (3) suggested exercises and exploratory actions. The LRC is also evaluating the VR-MM environment in order to optimize learning outcomes, training transfer, and cost effectiveness. These experiments are being designed to evaluate important VE system design issues including degree of immersion and affect on users' perception of depth in virtual space as indexed by perceptual motor task performance.
