Representations and Algorithms for Force-Feedback Display

Miguel A. Otaduy, Carlos Garre, Ming C. Lin
2013 Proceedings of the IEEE  
| "Haptic rendering" or "haptic display" can be broadly defined as conveying information about virtual objects or data to a user through the sense of touch.  ...  Among all applications of haptic rendering, force-feedback display of contact interactions with rigid and deformable virtual models through the sense of touch has matured considerably over the last decade  ...  Some enable the user to grasp virtual objects with springs for force feedback [53] ; others add skinning of a hand model [54] , a proxy-type skeleton and two-handed manipulation [55] , localized soft  ...

Design, Implementation and Control of an Underactuated Hand Exoskeleton [article]

Mine Sarac Stroppa
2020 arXiv   pre-print
Even though the proposed exoskeleton was designed with the purpose of assisting users during interactions with real objects around them, its use can be extended for haptic applications as well.  ...  I present the design, implementation and control of a novel, linkage-based, underactuated hand exoskeleton aimed to assist patients with hand disabilities during grasping tasks for robot assisted physical  ...  During a virtual grasping task, a haptic device should follow user's intentions with high transparency while providing resistance to user's fingers when encountered with the virtual object.  ...

Surface perception in a large workspace encounter interface

Emanuele Ruffaldi, Carlo Alberto Avizzano, Paolo Tripicchio, Antonio Frisoli, Massimo Bergamasco
2008 RO-MAN 2008 - The 17th IEEE International Symposium on Robot and Human Interactive Communication  
Haptic interaction with virtual objects is typically tool mediated, or in alternative it constraints user's body in someway, like it happens in exoskeletons that cannot be totally transparent.  ...  In this type of task this type of interface is better suited, providing a smoother feedback to the hand during the movement over the surface.  ...  The aim of a multiple finger interface is to provide not only the exploration of objects but also the grasping of objects [14] .  ...

Organic Shape Modeling through Haptic Devices

Renaud Ott, Daniel Thalmann, Frédéric Vexo
2006 Computer-Aided Design and Applications  
In fact, Designers feel well comfortable with this kind of primitives due to their ability in the organic shapes creation such as virtual humans.  ...  On the hardware side, it is based on the Haptic Workstation™ which conveys force feedback on the user arms (upper body limbs), and a Head Mounted Display to present the 3D generated images.  ...  Thus, the force feedback on fingers, conveyed by the CyberGrasp™, is not used to simulate the grasping: we use it to give initiatives to the user, so that he/she could make a particular posture of fingers  ...
