Complementary to automatic extraction processes, Virtual Reality technologies provide an adequate framework to integrate human perception in the exploration of large data sets. In such multisensory system, thanks to intuitive interactions, a user can take advantage of all his perceptual abilities in the exploration task. In this context the haptic perception, coupled to visual rendering, has be...

When teaching subjects richly infused with mathematics, in particular geometry, topology and shape modeling, there is a frequent problem that the learners are not able to “visualize” the attendant theoretical concepts. It is important, therefore, to constantly illustrate the associated theories with practical visual exercises, which are preferably to be done in collaboration with other learners...

In this contribution, we propose a new framework to evaluate pedestrian simulations by using Extended Range Telepresence. Telepresence is used as a virtual reality walking simulator, which provides the user with a realistic impression of being present and walking in a virtual environment that is much larger than the real physical environment, in which the user actually walks. The validation of ...

We demonstrate some preliminary results of the cutaneous haptic feedback device. The device is basically from the previous researches; however, our purpose is to achieve reality by exclusive usage of the cutaneous fingertip device. Thereby, we examine its feasibility and drawbacks, and improve the virtual reality.

We present a system for rendering planar rigid-body motion by means of a redundant parallel mechanism. The device design, the control architecture and the passive virtual environment simulation are presented. The system is used to compare various virtual walls and friction models proposed for haptic applications. In addition, the reset-integrator dry friction model proposed by Haessig and Fried...
