Algorithmically generated music enhances VR nephron simulation.

While sonification has enjoyed much attention in VR simulation studies, music has generally been incorporated as ambiance. This is partially due to difficulties with manipulating it interactively in real-time while maintaining a sensible musicality. This paper discusses how algorithmically generated music is used to provide ambiance, characterize the visual representation of molecular particle flow, provide orientation cues to the user, and enhance recognition of chemical gradient balances in a reified model of the kidney nephron. The technical obstacles related to the use of music in this context are also addressed.

Flatland sound services design supports virtual medical training simulations.

This paper describes the evolution of the design of Flatland Sound Service (FSS), a sound system for virtual reality required to support Project TOUCH (Telehealth Outreach for Unified Community Health), a multi-year collaboration between the Schools of Medicine at the state Universities of Hawaii and of New Mexico. Two virtual sonic environments specific case scenarios, a neurological trauma (Toma) and a virtual kidney nephron (Nephron), were developed using integrated services provided by FSS. Flatland is an open source visualization and virtual reality application development tool created at the University of New Mexico.

Virtual reality training improves students' knowledge structures of medical concepts.

Virtual environments can provide training that is difficult to achieve under normal circumstances. Medical students can work on high-risk cases in a realistic, time-critical environment, where students practice skills in a cognitively demanding and emotionally compelling situation. Research from cognitive science has shown that as students acquire domain expertise, their semantic organization of core domain concepts become more similar to those of an expert's. In the current study, we hypothesized that students' knowledge structures would become more expert-like as a result of their diagnosing and treating a patient experiencing a hematoma within a virtual environment. Forty-eight medical students diagnosed and treated a hematoma case within a fully immersed virtual environment. Student's semantic organization of 25 case-related concepts was assessed prior to and after training. Students' knowledge structures became more integrated and similar to an expert knowledge structure of the concepts as a result of the learning experience. The methods used here for eliciting, representing, and evaluating knowledge structures offer a sensitive and objective means for evaluating student learning in virtual environments and medical simulations.
