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. The haptic display system (morphling) of the invention that displays these characteristics comprises in principle three functional groups, which operate in synchronism with one another and with a visual subsystem. The individual subsystems can be operated statically or dynamically. In dynamic operation, users can change the position and/or shape, for example, of the tactile display by touching it. With regard to the real-time representation of the three-dimensional data of the user, at least the body part that is interacting with the object, e.g.
