The system according to the invention for haptic interaction with virtual objects comprises a visualisation unit for visualising virtual objects and the user's hand, a haptic output unit for reproducing haptic impressions at least by means of force feedback on fingertips of the user's hand, and a data processing unit for processing input data and controlling the visualisation unit and the output unit. The output unit has at least two movement-coupled segments of the interaction region, a finger-based positioning system, and a global positioning system, as well as a sensor system and actuator system. The movement-coupled segments are designed as touch surfaces, and each movement-coupled segment is assigned to one fingertip of the user's hand and can be moved by the latter. The position of the fingertip on the movement-coupled segment can be changed. The sensor system is used to detect the position of the movement-coupled segment with respect to the virtual object and the contact forces between the movement-coupled segments and the fingertips of the user's hand, while the actuator system serves for positioning the movement-coupled segments with respect to the virtual object and for exerting contact forces on the fingertips of the user's hand by means of the movement-coupled segments. A base reference plane for the force feedback is assigned to the haptic output unit.
