Summary:The hands are the most characteristic part of the human body from the standpoint that they are related to other elements through actions like grasping and touching. Several elaborate animation techniques for the hand with 3DCG have recently been proposed, but they are not good enough for simulations of hand touching, which requires simulation of complicated actions and position-dependent elastic forces in the hand. In this report, an algorithm is proposed which the user can operate intuitively for the deformation and the color change of the hand induced by touching. An outline of the algorithm is as follows; 1) elastic deformation, depending on the position of the hands, is controlled by channel images, and 2) color change is expressed by synthesizing three kinds of texture images.
