A Regression and Boundary-Crossing-Based Model for the Perception of Delayed Stiffness
Found in: IEEE Transactions on Haptics
By Ilana Nisky, Ferdinando A. Mussa-Ivaldi, Amir Karniel
Issue Date:July 2008
pp. 73-83
The stiffness of the environment with which we come in contact is the local derivative of a force field. The boundary of an elastic field is a singular region where local stiffness is ill-defined. We found that subjects interacting with delayed force field...
The Effect of Stiffness and Curvature on the Haptic Identification of Surfaces
Found in: World Haptics Conference
By Vikram S. Chib, James L. Patton, Kevin M. Lynch, Ferdinando A. Mussa-Ivaldi
Issue Date:March 2005
pp. 126-131
We performed experiments to investigate how humans acquire an internal representation of virtual objects through the execution of reaching movements across the object surface. Subjects were instructed to make reaching movements between points lying on the ...
Perception and Action in Teleoperated Needle Insertion
Found in: IEEE Transactions on Haptics
By Ilana Nisky,Assaf Pressman,Carla M. Pugh,Ferdinando A. Mussa-Ivaldi,Amir Karniel
Issue Date:July 2011
pp. 155-166
We studied the effect of delay on perception and action in contact with a force field that emulates elastic soft tissue with a rigid nonlinear boundary. Such a field is similar to forces exerted on a needle during teleoperated needle insertion. We found th...
Haptic Human-Robot Interaction
Found in: IEEE Transactions on Haptics
By Amir Karniel,Angelika Peer,Opher Donchin,Ferdinando A. Mussa-Ivaldi,Gerald E. Loeb
Issue Date:July 2012
pp. 193-195
The eight articles in this special section focus on haptic human-robot interaction. It had its origins in a tournament announced at the 7th Annual Computational Motor Control Workshop held June 2011 at Ben-Gurion University to compare algorithms for handsh...
Haptic Discrimination of Perturbing Fields and Object Boundaries
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Vikram S. Chib, James L. Patton, Kevin M. Lynch, Ferdinando A. Mussa-Ivaldi
Issue Date:March 2004
pp. 375-382
Experiments were performed to reveal how humans acquire information about the shape and mechanical properties of surfaces through touch and how this information affects the execution of trajectories over the surface. Subjects were instructed to make reachi...
Nonlinear Force Fields: A Distributed System of Control Primitives for Representing and Learning Movements
Found in: Computational Intelligence in Robotics and Automation, IEEE International Symposium on
By Ferdinando A. Mussa-Ivaldi
Issue Date:June 1997
pp. 84
Electrophysiological studies have suggested the presence of a modular structure in the output stages of the motor system. In this structure, independent modules are connected to specific groups of muscles and generate nonlinear fields of force acting upon ...
