Research Abstract

This research was aimed at investigating approaches to acquire models of deformable objects based on measurement and developing technology to realize haptic interaction with the acquired model. We employed the Impulse Response Deformation Model(IRDM) as a model to represent deformation and devised a method to measure impulse response of real deformable object. We also developed a fast computation algorithm of interaction with the model and a data compression method based on the redundancy of the IRDM.
