How realistic does the simulation need to be for effective training?
We are trying to find an answer to this question by conducting variety
of experiments .On the one hand, it is possible to learn the surgical
practices with an unrealistic model, which may lead to negative training
transfer. However, because of the learning abilities and perceptual limitations
of the sensory, motor, and cognitive system of the human user, perfect
simulation is unnecessary. Futhermore, given the large variations in human
anatomy and physiology, there is no single perfect model, and wide variations
exist in geometry an material properties of the organs. The main question
is how simple a simulation can we get away with, while at the same time
preserving a level of fidelity between the virtual and real organ behavior
that leads to positive training transfer. Thus, one goal of this
continuing study is to find out what is actually needed for effective
laparoscopic VR training prior to investing time and effort into developing
complicated models of human organs and tool-tissue interactions.
