Analysis and Modeling Based on Cepstrum for Haptic Presentation Considering Frequency Features of Vibration in Rubbing Motion

Abstract

This paper proposes a modeling method for the haptic information from the environmental characteristics of a plane. A human obtains much haptic information by touching an object. For the haptic information derived from a rubbing motion, this paper particularly focuses on the vibration components of the friction force. Although there are many methods to describe the friction force, it is difficult to treat them quantitatively. This paper proposes applying Cepstral analysis to haptic information to easily extract and treat unique features of the environment. A technique for representing the extracted frequency features is also presented. An experiment was performed using a 2 DOF system to show the validity of the proposal.

Recent advances and outlook in industrial instrumentation and mechatronics control

“…Haptics is expected to be widely useful for interactions between mechatronic sys‐tems and humans ,. As defined in a survey paper , ‘Haptics is a research field that examines information from physical interaction between humans and objects.…”
