Experimental Evaluation of Attachment Methods for a Multifinger Haptic Device
Due to the nature of touch sensation, the interface between a user and a haptic device must be carefully designed and selected such that the user feels they are directly manipulat...

An Experimentally Verified Model of the Perceived 'Coldness' of Objects
In this paper, a numerical model of the thermal process of touching an object is described. The model takes into account the object geometry and temperature, the thermal parameter...

Vibration Enhances Geometry Perception with Tactile Shape Displays
Tactile displays can provide detailed spatial information to the skin, but little is known about the effects of vibrating displayed shapes. This study examines passive touch perce...

Assessing the Efficacy of Variable Compliance Tactile Displays
Tactile displays based on pin arrays are challenging to design because they require a large number of individually controllable pins, or "tactors". A semiactive approach...

Effects of Translational and Gripping Force Feedback are Decoupled in a 4-Degree-of-Freedom Telemanipulator
Many high-degree-of-freedom haptic devices and teleoperator systems either do not have grippers or do not provide force feedback in the gripper degree of freedom (DOF). The purpos...

A Behavioral Adaptation Approach to Identifying Visual Dependence of Haptic Perception
Both haptic and visual senses play a role in how we explore our environment. Previous studies have shown that vision plays a very strong role in perception of object stiffness, ye...

Enhancing Transparency of a Position-Exchange Teleoperator
Dynamic properties of robotic manipulators, including inertia, damping, and friction, limit the transparency of a haptic-feedback teleoperator. In this paper, we develop a positio...

Incorporating Geometric Algorithms in Impedance- and Admittance-Type Haptic Rendering
Geometric (proxy-based) haptic rendering algorithms are widely used in impedance-type haptic rendering. Such methods are useful for developing complex virtual environment because ...
