Virtual reality in medical education and assessment

摘要

The NASA Johnson Space Center (JSC)/LinCom Corporation, the University of Texas Medical Branch at Galveston (UTMB), and the Galveston Independent School District (GISD) have teamed up to develop a virtual visual environment display (VIVED) that provides a unique educational experience using virtual reality (VR) technologies. The VIVED end product will be a self-contained educational experience allowing students a new method of learning as they interact with the subject matter through VR. This type of interface is intuitive and utilizes spatial and psychomotor abilities which are now constrained or reduced by the current two dimensional terminals and keyboards. The perpetual challenge to educators remains the identification and development of methodologies which conform the learners abilities and preferences. The unique aspects of VR provide an opportunity to explore a new educational experience. Endowing medical students with an understanding of the human body poses some difficulty challenges. One of the most difficult is to convey the three dimensional nature of anatomical structures. The ideal environment for addressing this problem would be one that allows students to become small enough to enter the body and travel through it - much like a person walks through a building. By using VR technology, this effect can be achieved; when VR is combined with multimedia technologies, the effect can be spectacular.
