Abstract DECAFF is a method for design and control of haptic interfaces that utilizes a DE-Coupled Actuator and Feed-Forward control. In this paper results of an experimental investigation are presented that quantify improved human haptic perception while using the DECAFF system, compared to the traditional haptic interface design and control systems. Perception improvements include the increased stability for rigid surfaces and increased ability of subjects to accurately identify initial contact with virtual surface boundaries. Traditional haptic interfaces employ an actuator directly coupled to the human operator that provides a force proportional to wall penetration distance and velocity. The DECAFF paradigm for design and control of haptic displays utilizes a de-coupled actuator and pre-contact distance sensing as a feed forward control term to improve stability and response performance. A human perception experiment has been performed that compares the touch sensation of the subjects for both the DECAFF system and traditional approaches to haptic display. In the human factors study the quality of rigid body display is evaluated in addition to the sensitivity of touch experienced by the subjects while making initial contact with virtual surfaces.

She was also an Associate of the Canadian Institute for Advanced Research in the Robotics and Artificial Intelligence Programme for 8 years. A Professor in the Departments of Psychology and Computing & Information Science at Queen's University at Kingston (Ontario, Canada), she has written and coauthored numerous articles on tactile psychophysics, haptic perception and cognition, motor control, and haptic applications in robotics, teleoperation, and virtual environments. She is currently the coorganizer of the Annual Symposium a Haptic Interfaces for Teleoperation and Virtual Environment Systems. René Verry (RV) is a psychology professor at Millikin University (Decatur, IL), where she teaches a variety of courses in the experimental core, including Sensation and Perception. She chose the often-subordinated somatic senses as the focus of her interview, and recruited Susan Lederman as our research specialist.
