Abstract

This paper presents a new conservative criterion of stable haptic interaction using damping model. The relation among the damping coefficient, device's position resolution and sampling frequency is obtained to keep the haptic simulations stable. Our analysis is tested with a damping model which is constructed for the dental training system. The experimental results indicate that the increasing of damping coefficient depends on more precise encoders.
