Summary
Objectives:
This paper intends to investigate the role of virtual reality (VR) in medicine. In
particular it outlines the current state of research and technology that is relevant
to the development of effective virtual environments in medicine.
Methods:
After describing the two different visions of VR we can find in medicine – the presentation
of virtual objects to all of the human senses in a way identical to their natural
counterpart, and a new human-computer interaction paradigm in which users are active
participants within a computer-generated three-dimensional virtual world – the paper
presents some of the most interesting applications actually developed in the area.
Finally, it discusses the clinical principles, technological devices and safety issues
associated with the use of VR in medicine.
Results:
With more than 1,000 VR papers already indexed in Medline, VR is a reality health
care. Even if the number of controlled studies is still limited, its merging with
emerging technologies like Ambient Intelligence and wireless communication will further
improve its diffusion.
Conclusions:
The possible impact of VR on health care could be even higher than the one offered
by the new communication technologies like Internet. In fact, VR is at the same tima
technology, a communication interface and an experience: a communication interface
based on interactive 3D visualization, able to collect and integrate in single real-like
experience different inputs and data sets. However, significant efforts are still
required to move VR into commercial success and therefore routine clinical use.
