Stiffness discrimination with visual and proprioceptive cues
Found in: World Haptics Conference
By Netta Gurari, Katherine J. Kuchenbecker, Allison M. Okamura
Issue Date:March 2009

This study compares the Weber fraction for human perception of stiffness among three conditions: vision, proprioceptive motion feedback, and their combination. To make comparisons between these feedback conditions, a novel haptic device was designed that s...
Shaping Event-Based Haptic Transients Via an Improved Understanding of Real Contact Dynamics
Found in: World Haptics Conference
By Jonathan P. Fiene, Katherine J. Kuchenbecker
Issue Date:March 2007
pp. 170-175
Haptic interactions with stiff virtual surfaces feel more realistic when a short-duration transient is added to the spring force at contact. But how should this event-based transient be shaped? To answer this question, we present a targeted user study on v...
Quantifying the Value of Visual and Haptic Position Feedback During Force-Based Motion Control
Found in: World Haptics Conference
By Katherine J. Kuchenbecker, Netta Gurari, Allison M. Okamura

Controlling the motion of a prosthetic upper limb without visual feedback is extremely difficult because the wearer does not know the prosthesis? configuration. This paper describes an experiment designed to determine the relative importance of visual and ...
Event-Based Haptic Tapping with Grip Force Compensation
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Jonathan Fiene, Katherine J. Kuchenbecker, Gunter Niemeyer
Issue Date:March 2006
pp. 19
Previous work in event-based haptics has demonstrated that augmenting position-based force feedback with high-frequency impact transients significantly improves the realism of virtual tapping. Transients can be portrayed more accurately by accounting for t...
Creating Realistic Virtual Textures from Contact Acceleration Data
Found in: IEEE Transactions on Haptics
By Joseph M. Romano,Katherine J. Kuchenbecker
Issue Date:January 2012
pp. 109-119
Modern haptic interfaces are adept at conveying the large-scale shape of virtual objects, but they often provide unrealistic or no feedback when it comes to the microscopic details of surface texture. Direct texture-rendering challenges the state of the ar...
Haptic Display of Contact Location

By Katherine J. Kuchenbecker, William R. Provancher, Günter Niemeyer, Mark R. Cutkosky
Issue Date:March 2004
pp. 40-47
This work presents a new haptic device that integrates contact location feedback with grounded point-force display. The system consists of a thimble-based mechanism attached to the endpoint of a Phantom® robotic arm. Contact location is rendered using a sm...
Vibrotactile feedback system for intuitive upper-limb rehabilitation

By Pulkit Kapur, Sunthar Premakumar, Steven A. Jax, Laurel J. Buxbaum, Amanda M. Dawson, Katherine J. Kuchenbecker
Issue Date:March 2009
pp. 621-622
The proposed demonstration stems from research on a low cost haptic virtual interaction platform for upper-limb rehabilitation. This work centers on the use of vibrotactile feedback in a virtual environment to help stroke patients perform simple repetitive...
Evaluation of Tactile Feedback Methods for Wrist Rotation Guidance
Found in: IEEE Transactions on Haptics
By Andrew A. Stanley,Katherine J. Kuchenbecker
Issue Date:July 2012
pp. 240-251
Tactile motion guidance systems aim to direct the user's movement toward a target pose or trajectory by delivering tactile cues through lightweight wearable actuators. This study evaluates 10 forms of tactile feedback for guidance of wrist rotation to unde...
Tool Contact Acceleration Feedback for Telerobotic Surgery
Found in: IEEE Transactions on Haptics
By William McMahan,Jamie Gewirtz,Dorsey Standish,Paul Martin,Jacquelyn A. Kunkel,Magalie Lilavois,Alexei Wedmid,David I. Lee,Katherine J. Kuchenbecker
Issue Date:July 2011
pp. 210-220
Minimally invasive telerobotic surgical systems enable surgeons to perform complicated procedures without large incisions. Unfortunately, these systems typically do not provide the surgeon with sensory feedback aside from stereoscopic vision. We have, thus...
Toward tactilely transparent gloves: Collocated slip sensing and bibrotactile actuation
Found in: World Haptics Conference
By Joseph M. Romano, Steven R. Gray, Nathan T. Jacobs, Katherine J. Kuchenbecker
Issue Date:March 2009
pp. 279-284
Tactile information plays a critical role in the human ability to manipulate objects with one's hands. Many environments require the use of protective gloves that diminish essential tactile feedback. Under these circumstances, seemingly simple tasks such a...
A high fidelity ungrounded torque feedback device: The iTorqU 2.0
Found in: World Haptics Conference
By Kyle N. Winfree, Jamie Gewirtz, Thomas Mather, Jonathan Fiene, Katherine J. Kuchenbecker
Issue Date:March 2009
pp. 261-266
This paper discusses the design and operation of the iTorqU 2.0, an ungrounded, handheld torque feedback device for haptic applications. Based upon the gyroscopic effect, the iTorqU 2.0 uses a metal flywheel inside of a two-axis actuated gimbal to create d...
Displaying realistic contact accelerations via a dedicated vibration actuator
Found in: World Haptics Conference
By William McMahan, Katherine J. Kuchenbecker
Issue Date:March 2009
pp. 613-614
During real physical interactions, contact between a hand-held tool and an object causes high-frequency tool accelerations that are detected by mechanoreceptors in the human hand. These haptic signals provide salient cues about changes in tool-surface cont...
Event-Based Haptics and Acceleration Matching: Portraying and Assessing the Realism of Contact
Found in: World Haptics Conference
By Katherine J. Kuchenbecker, Jonathan Fiene, Günter Niemeyer
Issue Date:March 2005
pp. 381-387
Contact in a typical haptic environment resembles the experience of tapping on soft foam, rather than on a hard object. Event-based, high-frequency transient forces must be superimposed with traditional proportional feedback to provide realistic haptic cue...
