Haptic Interaction with Global Deformations

by Yan Zhuang, John Canny , 2000
"... Force feedback coupled with a real-time physically realistic graphic display provides a human operator with an artificial sense of presence in a virtual environment. Furthermore, it allows a human operator to interact with the virtual environment through "touch". In this paper, we describe ..."

A constraint-based god-object method for haptic display

by C. B. Zilles, J. K. Salisbury - In International Conference on Intelligent Robots and Systems , 1995
"... Haptic display is the process of applying forces to a human \observer " giving the sensation of touching and interacting with real physical objects. Touch is unique among the senses because it allows simultaneous exploration and manipulation of an environment. A haptic display system has three ..."

for generating convincing interaction forces for objects modeled as rigid polyhedra (Fig. 1). We create a virtual model of the haptic interface, called the god-object, which conforms to the virtual environment. The haptic interface can then be servo-ed to this virtual model. This algorithm is extensible to other

Assessing the fidelity of the haptically rendered deformable objects

by Matthias Harders, Computer Vision Laborarory - In Haptic Interfaces for Virtual Environment and Teleoperator Systems, IEEE VR , 2006
"... A central element of surgical simulators is the generation of ap-propriate haptic feedback. Several factors inuence this rendering process, which could potentially degrade the feedback quality. In this context, our current research aims at assessing, how well hap-tic sensations encountered during in ..."

interaction with real objects, can actually be approximated in a virtual environment. Since nding appropriate soft tissue deformation models for real time interaction is a complex task in itself, we limited the investigations in this pilot study to simple linear-elastic silicone objects. A model of a virtual

Haptics issues in virtual environments

by Grigore C. Burdea - In Computer Graphics International, 2000. Proceedings , 2000
"... Haptics is a recent enhancement to virtual environments allowing users to “touch ” and feel the simulated objects they interact with. Current commercial products allow tactile feedback through desktop interfaces (such as the FEELItä mouse or the PHANToMä arm) and dextrous tactile and force feedback ..."

Haptic Interaction in Virtual Environments

by Diego C. Ruspini, Krasimir Kolarov, Oussama Khatib - In Proc. of the IEEE-RSJ Int. Conf. on Intelligent Robots and Systems , 1997
"... We present a haptic rendering framework that allows the tactile display of complex virtual environments. This framework allows surface constraints, surface shading, friction, texture and other effects to be modeled solely by updating the position of a representative object, the "virtual proxy.& ..."

Virtual Environment rendering

by John M. Hollerbach, David E. Johnson - in Human and Machine Haptics , 2000
"... 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 an ..."
