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...

Event-Based Haptics and Acceleration Matching: Portraying and Assessing the Realism of Contact
Contact in a typical haptic environment resembles the experience of tapping on soft foam, rather than on a hard object. Event-based, high-frequency transient forces must be superi...
