Abstract
In this paper, we propose an analytic deformation model of skin. We applied
our method to the medical training system for central venous injection
which is a part of central venous catheter (CVC) placement. The training
system renders a human body with haptic interaction using PHANToM haptic
device. In such VR system, it is important to synchronize the visual representation
with haptic interaction. Therefore, it is need to deform the skin when
it is touched. A number of researches have been done in animation of deformable
bodies. However, they are usually computationally intensive, especially
for the large polygons. We propose C-LEM using approximate solution of
base equation in LEM which is proposed by Remis. B et al to exclude the
computation of liner system. The parameter of the proposed model was determined
by minimizing the error between shapes of the model and measured.
