We describe a system for interacting with shapes in two dimensional images with force feedback, using haptic devices. We construct multiresolution models of boundary curves in images, using wavelet multiresolution with good approximation properties. The boundary curves are treated as solid objects that will produce a force when pushed with a mouse-like haptic interface. This interaction force i...

Physical interaction is a key aspect of pervasive games. Although physical affordances are exploited, games are missing certain kinds of feedbacks on the interface and/or interaction levels: Haptic feedback in pervasive games is still an open issue. This paper discusses feedback in pervasive games. To illustrate the ideas, our work on Haptic Airkanoid, an extension to Airkanoid, is presented. F...

We have developed a computer interface that simultaneously renders integrated auditory and haptic stimuli with very low latency. The interface includes a three degree of freedom (DOF) Pantograph haptic device that reads position input and renders force output. We synthesize audio by convolving the force profile generated by user interaction with the impulse response of the virtual surface. Thus...

In this paper, we propose a new concept of visual/haptic interfaces called WYSIWYF display. The proposed concept provides correct visual/haptic registration using a visionbased object tracking technique and a video keying technique so that what the user can see via a visual interface is consistent with what he/she can feel through a haptic interface. Using Chroma Keying, a live video image of t...

The reproduced tactile sensation of haptic interfaces usually selectively reproduces a certain object attribute, such as the object's material reflected by vibration and its surface shape by a pneumatic nozzle array. Tactile biomechanics investigates the relation between responses to an external load stimulus and tactile perception and guides the design of haptic interface devices via a tactile...

This paper analyzes the design of a force-based impedance control for a haptic interface system characterized by a parallel kinematics. By exploiting the features of parallel mechanisms, which perform better than the serial ones in terms of dynamic performance, stiffness and position accuracy, and by implementing a closed-loop force control, the transparency of a haptic master system and the Žd...

When humans interface with machines, the control interface is usually passive and its response contains little information pertinent to the state of the environment. Usually, information flows through the interface from human to machine but not so often in the reverse direction. This work proposes a control architecture in which bi-directional information transfer occurs across the control inte...

In this paper, we are presenting a new type of pointing interface for computers which provides mouse functionalities with near surface haptic feedback. Further, it can be configured as a haptic display where users may feel the basic geometrical shapes in the GUI by moving the finger on top of the device surface. By mapping the motion and identifying the polarity of a neodymium magnet which atta...

A virtual environment (VE) may represent a simulation of a real environment or of an artificial environment, such as in scientific visualization of data. For haptic interaction with a VE, the simulation has to compute some kind of geometrical relationship between positions of the haptic interface and objects in the VE, and then based on this geomety to compute an interaction force arising from ...
