インパルス応答変形モデルのための柔らかさ情報の圧縮手法の検討

摘要

本論文では，インパルス応答変形モデルのメモリ使用量の問題を解決するための圧縮手法について検討した.今後は，再生システムへの実装を進めるとともに，生成される力覚の現実感の評価や，圧縮率の更なる改善等を行う予定である.%In this paper, an elasticity information compression method for impulse response deformation model is discussed. In our past paper, we proposed an approach to haptic interaction with dynamically deformable object. In the approach, the behavior of an object is defined by a set of temporal deformation patterns after impulse force is applied to each degree of freedom, which we call impulse response deformation model. The time complexity of computing interaction force is independent of the complexity of the model, however, vast memory is required to store variety of impulse responses. To solve this problem, we discuss about compression method of the impulse renponses.
