This paper presents a framework for retrieving motion data which can be used for synthesizing a realistic motion of human character with various features, such as the weight of each body-segment. Since it is generally difficult to generate a realistic motion such as human's motion, we take account of an amount of energy change, which we consider to be one element of the reality of human's motion, on the character's each joint and bodysegment that is required during the motion. That is, we define the motion with the minimum amount of energy change as the realistic motion for the character in the sense that the motion can be performed concerning the various features of the character. Therefore in our framework, we try to synthesize a target motion by retrieving motion data and connecting retrieved data so that the amount of energy change is made the minimum. However, as the calculation of the amount of energy change takes much time, we cannot use it for a similarity to retrieve the data. Therefore, we have to define the similarity for which the few amount of calculation is required and that needs to maintain the reality of the character's motion. The similarity between frames is measured in the amount of the approximated energy change. By using the approximated energy change, the time required by retrieving can be reduced and by using the energy change and the approximated energy change together, we can connect the retrieved data realistically. Some experimental results to show the effectiveness of our approach are also presented.
