Virtual Reality becomes more and more important within the product development process. It enables the engineer to realize constraints or mistakes in the product design at a very early stage by viewing the digital geometric prototype. Beside viewing the design of a product, additional functionalities like simulation of assembling, the physically correct behavior of a machine or the machine control come into focus of interest. Therefore, the interaction modality of haptic feedback gains more and more importance for simulation tasks in virtual environments. However there are only a few portable haptic interfaces with which the user can experience in a natural way the sensation of force feedback.
The scope of this paper is to present a new passive haptic interface that is lightweight and easy to use. Furthermore it has no constraints in the workspace and applies high forces to the fingertips of the user by blocking the natural grasping.
