چکیده

This article presents a classification of and comparison between isotonic, isometric and elastic devices. It then introduces the DigiHaptic, a new three degrees of freedom multi-finger force feedback device, and its place in the device classification is proposed. Two notable features of the DigiHaptic are the decoupling of the degrees of freedom and the correlation between fingers and objects movements. Finally two force feedback solutions using the DigiHaptic in elastic mode are proposed for rate control in open and closed workspaces.

The DigiHaptic, a New Three Degrees of Freedom Multi-finger Haptic Device

This article presents the technical principles and a set of applications for a new ground-based three degrees of freedom haptic device. The DigiHaptic can be used in isometric or isotonic mode with force feedback. It is a new and original approach to object manipulation in virtual worlds using degrees of freedom decoupling. The process which led us to create the DigiHaptic was based on a change...

Does DOF Separation on Elastic Devices Improve User 3D Steering Task Performance?

We investigated the use of a new haptic device called the DigiHaptic in a 3D steering task. Unlike other devices intended to interact in 3D with one end-effector, the DigiHaptic has three levers that the user may handle simultaneously or not in elastic mode to rate control objects. We compared it to the SpaceMouse another elastic device to evaluate the influence that degrees of freedom (DOF) se...

Multi-fingered exoskeleton haptic device using passive force feedback for dexterous teleoperation

A novel control methodology for master-slave systems using passive force feedback has been proposed by the authors. The methodology solves the conventional problems of previously developed master-slave systems with force feedback, such as oscillations, complex structures and complicated control algorithm. In the present paper, a multi-fingered exoskeleton haptic device (master hand) with passiv...

Multi-Fingered Grasping and Manipulation in Virtual Environments Using an Isometric Finger Device

In this article we present a new isometric input device for multi-fingered grasping in virtual environments. The device was designed to simultaneously assess forces applied by the thumb, index, and middle finger. A mathematical model of grasping, adopted from the analysis of multi-fingered robot hands, was applied to achieve multi-fingered interaction with virtual objects. We used the concept o...

Presenting grasping and resultant forces for rigid body manipulations with multi-finger haptic interfaces

We measure grasping and resultant forces and reveal that the grasping force is kept stable while subjects shake objects. Then, we propose a new method to feedback grasping and resultant forces for multi-finger object manipulation. While shaking an object, the proposed method keeps the grasping force and eliminates the influence of the resultant force to the distance between fingers. We do an ex...
