This paper argues that the goal of reducing the differences between features within a 3D model and the use of 3D haptic space of the force feedback device is not necessarily desirable. We present the idea of a non-realistic haptic rendering system. We examine in detail the mapping of 3D data structures onto 3D haptic space and show the use of information(More)
Haptic displays provide force feedback for a wide range of applications. During the haptic representation of virtual objects, one of the central tasks is to find out whether the user is inside the defined geometry and the calculation of the point on the surface to which the reaction force is directed. Our paper presents a new fast algorithm for collision(More)
In this paper we present methods which allow users to orient themselves and navigate through haptic-only environments. The fundamental idea is to use non-realistic haptic rendering to organize and structure the scene into different planes. Based on these planes, we use additional natural language and haptic information to provide the users with help for(More)
The integration of efficient implementation techniques, which have been proven in manual coding, into FDT compilers is difficult because of the semantic constraints of the FDTs and the lack of language means to flexibly adapt to a given implementation context. In this paper, we discuss ways to improve the efficiency of automated protocol implementations to(More)
