OBJECTIVE This work lays the foundation for future research on quantitative modeling of human stiffness perception. Our goal was to develop a method by which a human's ability to perceive suprathreshold haptic force stimuli and haptic stiffness stimuli can be affected by adding haptic noise. METHODS Five human participants performed a same-different task with a one-degree-of-freedom force-fee...

This study investigated cross-modal links in attention between haptics and vision. A visual change-detection task was used as a measure of visual attention. Haptic taps on the back was used to prompt the user the visual quadrant within which changes occurred. The location of the haptic cues was consistent with the quadrant of the visual changes on either 80% or 20% of the trials. Ten subjects w...

The concept of a new mobile haptic interface for unconstrained bimanual manipulation is presented. This device, which has been developed at the High-Fidelity Telepresence and Teleaction Research Centre, Munich, Germany, allows locomotion and haptic interaction at the same time. In contrast to most existing haptic interfaces, it is therefore not restricted to desktop applications but also enable...

In this paper, we make a comparison of haptic control schemes (position-position and position-force control schemes) for two haptic teleoperation systems by QoE (quality of experience) assessment. One is a remote control system with haptic media and video. In the system, we can write characters by controlling a haptic interface device at a remote place with another haptic interface device while...

A haptic interface is a kinesthetic link between a human operator and a virtual environment. This paper addresses fundamental stability and performance issues associated with haptic interaction. It generalizes and extends the concept of a virtual coupling network, an artificial link between the haptic display and a virtual world, to include both the impedance and admittance models of haptic int...

Interactions with virtual worlds using the sense of touch, called haptic rendering, have natural applications in many domains such as health or industry. For an accurate and realistic haptic feedback, the haptic device must receive orders at high frequencies, especially to render stiff contacts between rigid bodies. Therefore, it is today still challenging to provide consistent haptic feedback ...

We motivate and discuss the design of a physically intuitive haptic drumstick. A new musical instrument is physically intuitive if the physics of haptic interaction are similar to those supported by a traditional musical instrument. We suggest that physically intuitive new musical instruments may help performers transfer motor skills from familiar, traditional musical instruments. Both actively...

One of most interesting aspects in haptic research deals with the extension of application workspace, thus allowing haptic simulation within large virtual environments. Several devices have been realized that allow this kind of interaction, in particular our interest focuses on mobile haptic interfaces, realized by combining classic grounded haptic devices with mobile platforms. While grounded ...

Force feedback control is investigated for improving the quality of the haptic feedback in virtual reality applications. Advanced control design can increase the transparency of the haptic device at the haptic interface thereby increasing the realism of the simulation. Force feedback also enables the implementation of admittance control approaches heretofore considered the domain of large robot...
