Passive and Active Discrimination of Natural Frequency of Virtual Dynamic Systems
Found in: IEEE Transactions on Haptics
By Ali Israr, Yanfang Li, Volkan Patoglu, Marcia K. O'Malley
Issue Date:January 2009

It has been shown that humans use combined feedforward and feedback control strategies when manipulating external dynamic systems, and when exciting virtual dynamic systems at resonance, that they can tune their control parameters in response to changing n...
 
The Task-Dependent Efficacy of Shared-Control Haptic Guidance Paradigms
Found in: IEEE Transactions on Haptics
By Dane Powell,Marcia K. O'Malley
Issue Date:July 2012
pp. 208-219
Shared-control haptic guidance is a common form of robot-mediated training used to teach novice subjects to perform dynamic tasks. Shared-control guidance is distinct from more traditional guidance controllers, such as virtual fixtures, in that it provides...

Haptic feedback can be a critical component of virtual environments used in cognitive research, rehabilitation, military training, and entertainment.
 
Compact and low-cost tendon vibrator for inducing proprioceptive illusions
Found in: World Haptics Conference
By Ozkan Celik, Marcia K. O'Malley, R. Brent Gillespie, Patricia A. Shewokis, Jose Luis Contreras-Vidal
Issue Date:March 2009
pp. 623-624
Recent literature suggests that inducing proprioceptive movement illusions with predefined movement trajectories via tendon vibration requires use of multiple vibrators and precisely controlled frequency profiles. In this study, we report the design, model...
 
Visual versus haptic progressive guidance for training in a virtual dynamic task
Found in: World Haptics Conference
By Joel C. Huegel, Marcia K. O'Malley
Issue Date:March 2009
pp. 399-400
The objective of this work is to demonstrate that progressive haptic guidance can accelerate and improve motor task training outcomes over visual or practice-only methods in a training virtual environment (TVE). To that end, we design haptic and visual gui...
 
A low cost vibrotactile array to manage respiratory motion
Found in: World Haptics Conference
By Ali Israr, Dillon P. Eng, Sastry S. Vedam, Marcia K. O'Malley
Issue Date:March 2009
pp. 619-620
We present a tactile Respiratory Management System (tRMS) to manage and control breathing patterns of cancer patients undergoing radiation therapy. The system comprises of an array of small vibrating motors and a control box that supplies power to and prov...
 
Progressive shared control for training in virtual environments
Found in: World Haptics Conference
By Yanfang Li, Joel C. Huegel, Volkan Patoglu, Marcia K. O'Malley
Issue Date:March 2009
pp. 332-337
Virtual environments (VEs) with haptic feedback not only provide a safe and versatile practice medium for many manual control tasks, but also promise to improve the efficacy of manual skill training with the addition of haptic guidance. However, haptic gui...
 
Effects of magnitude and phase cues on human motor adaptation
Found in: World Haptics Conference
By Ali Israr, Hakan Kapson, Volkan Patoglu, Marcia K. O'Malley
Issue Date:March 2009
pp. 344-349
Recent findings have shown that humans can adapt their internal control model to account for the changing dynamics of systems they manipulate. In this paper, we explore the effects of magnitude and phase cues on human motor adaptation. In our experiments, ...
 
Towards Just Noticeable Differences for Natural Frequency of Manually Excited Virtual Dynamic Systems
Found in: World Haptics Conference
By Yanfang Li, Volkan Patoglu, Deborah Huang, Marcia K. O'Malley
Issue Date:March 2007
pp. 569-570
This paper explores the experiment design to determine a human?s ability to discriminate the natural frequency of manually excited virtual dynamic systems. We use a one degree-of-freedom haptic interface with a coupled graphical display to render a virtual...

Performance Enhancement of a Haptic Arm Exoskeleton
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Alan Sledd, Marcia K. O'Malley
Issue Date:March 2006
pp. 58
A high-quality haptic interface is typically characterized by low apparent inertia and damping, high structural stiffness, minimal backlash, and absence of mechanical singularities in the workspace. In addition to these specifications, exoskeleton haptic i...
