Evaluation of a virtual reality system for medicine

We are currently developing a virtual reality system for cancer diagnosis and treatment. The new technology of virtual reality will be applied to a surgical simulation system. a new diagnostic system, a palliative care support system and an informed consent support system. In the research and development of this virtual reality system we need a method to evaluate it for practical use. For evaluating a medical virtual reality system. we propose the equation S (S: System factor = Sp: presentation factor, Sm: measurement and control factor, So: operation system factor)= alpha . A/H (A: Application factor, H: Human factor, alpha : a coefficient). We think that the human factor is the mast important consideration for the development of a medical virtual reality system.
