VIRTUAL-REALITY IN MEDICINE

The methods of virtual reality (VR) will come to play a routine part i n the work of hospitals. It is difficult to understand and explain wha t VR means in medicine and its scope in medicine. This paper distingui shes the four functional categories of Immersive VR, Desktop VR, Pseud o VR and Inverse VR. Immersive VR uses a head-mounted display and data gloves as input devices, while Desktop VR uses VR shutter glasses and a 3D input device such as the 3D mouse. Pseudo VR comprises interacti ve controllable animation. Inverse VR uses, for example, biosignals as an input device in order to support the computer user in the real wor ld. This paper discusses the potential applications of the four catego ries of VR in medicine with reference to topical projects.
