Extending the Z-Width of a Haptic Device Using Acceleration Feedback
Abstract. This paper proposes a nonlinear controller to extend the Zwidth of a haptic device. A time-domain passivity analysis of the Z-width diagram leads to the new haptic contro...

Motion editing with data glove
In this paper, we propose a new method to edit captured human motion data by using the data glove. The animator first wears a glove and mimics the human body motion observed in t...
