Real-time Generation of Impact Vibrations based on Physical Models for Representing Impulsive Collision Feelings

Abstract

We developed a real-time waveform generation model for representing impulsive collisional sensation using the RungeKutta method based on a contact mechanics and vibration propagation model, which were proposed previously by the authors’group. The developed model can generate vibrations depending on the stiffness of hitting objects and hitting speed for VR applications. As an example of applications, we measured vibrations occurred on the drumstick when it struck a snare drum and determined the parameters. Comparisons with the measured data demonstrated that our model could reproduce similar vibration waveforms.
