Abstract: The invention relates to a system and a method for haptic interaction with virtual objects. The system of the invention is based on the idea that, for the haptic representation of any virtual three-dimensional object—synchronized with the visual representation—only the tangible haptic characteristics of the surface area of the object at the collision point or the area of contact are important.
