We propose 'the haptic primitive' for haptic rendering without the need to solve complicated parametric equations. To develop 'the haptic primitive', we adopted "the God-Object Method" as a haptic rendering algorithm and applied 'Constructive Solid Geometry' to manage haptic objects. Besides being used in the 'ghost library' of $PHANToMTM^{TM}$ our method can be used as a basic component for developing tools and libraries that aim to simplify haptic modeling. It can also be applied to tactile display modules and temporal display modules. Ultimately it can be developed into a one-stop haptic modeling tool that enables the user to more conveniently create a tangible CAD systems or a tangible e-ommerce system.

The theories of optical/haptic perception provide us contrasting insights into the perception of space in movie and architecture. Through the lenses of these theories, this study aims to analyse the optical and haptical aspect of the medieval library of the film, The Name of the Rose. The dominance of vision over the other senses has been maintained by many philosophers, such as Plato, Aristotle, and Aquinas, and this trend leads to the development of the hierarchical and perspective space of Renaissance and Modern Architecture. Those conceptions of optical space help us not only identify space as clear and distinct three-dimensional entity but also separate the subject and the object. However, tactile/haptic perception is more useful to explain the experience of film and contemporary architecture than optical perception. This haptic space is developed by Alois Riegl, Walter Benjamin, and Gilles Deleuze. This study intends to search for the difference between two perceptions on the architectural space of the movie, examine the relation between architecture and human, space and user.

In this paper, we propose a new graphic deformation algorithm for haptic interface system. Our deformable model is based on non-linear elasticity, anisotropy behavior and the finite element method. Also we developed controller for high-speed communication. The proposed controller is based on the PCI/FPGA technology, which could progress the capability of the position calculating and the force data transmitting. The haptic system is composed of the 6DOF force display device, the high-speed controller, HIR library for 3D graphic deformation algorithm and the haptic rendering algorithm. The developed system will be used on constructing the dynamical virtual environment. We demonstrate the relevance of this approach for the real-time simulating deformations of elastic objects. To show the efficiency of our system, we programmed the simulation of force reflecting. As the result of experiment, we found that it has high stability and easy to control for deformable object than some other systems.

In this paper, we have developed a new Force-Display system using wire-tension method. The proposed system is based on the HIR Lab Haptic Rendering library, which calculates the real position and renders the reflecting force data to device rapidly. The system is composed of device based tendon-driven method, controller and Haptic rendering library. The developed system will be used on constructing the dynamical virtual environment. To show the efficiency of our system, we designed simulation program which can display the moving force (attaching, grabbing, rotating) on two virtual point. As the result of the experiment, our proposed system shows much higher resolution and stability than any others.
