Perceptual Cues for Orientation in a Two Finger Haptic Grasp Task

Reach & Grasp Therapy: Design and Control of a 9-DOF Robotic Neuro-rehabilitation System

“…The Cybergraspl glove allows for the representation of forces due to grasping a virtual object but its ungrounded design cannot represent forces due to mass or weight. Melder and Harwin [8] demonstrated a general method for representing multi-finger grasp forces as well as inertial and gravitational forces on a virtual object, a technique evaluated by McKnight et al [9]. Simple two finger devices were used by the Frisoli et al [10] for the exoskeleton haptic interface developed for the 1 Manufactured by Immersion.com 1-4244-1320-6/07/$25.00 (c)2007 IEEE museum of pure form.…”

Haptic-enabled collaborative learning in virtual reality for schools

“…A key advantage of multi-finger haptics is that they provide a natural method to position and orientate objects in 6 dimensions, three positions, and three orientations. When compared to visual cues that include shadows and stereo vision multi-finger haptic interfaces have been shown to be superior to accurate positioning of objects in both position and orientation (McKnight et al, 2005). Multi-finger haptic interfaces have no effect on the speed of task completion (ibid).…”
