Abstract: The invention relates to a device and its use for multiphoton printing for the additive manufacture of three-dimensional structures or for the inspection of these and other structures of comparable size ratios in the presence of an inspection medium. In order to manufacture and inspect three-dimensional structures that have varying properties and/or material compositions, the device according to the invention is characterized by a locally selective material feed (9), a locally selective material discharge (11) and locally selective, focused emission or reception of electromagnetic radiation.

Abstract: 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.

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.

Abstract: The invention relates to a system and a method for haptic interaction with visually presented objects. In the process, three-dimensional data of the user and an object are captured and presented in a visual subsystem. At the same time, there is an interaction of the user with a haptic element in a haptic subsystem, wherein the haptic element is designed in such a way that it can imitate the surface characteristics of the object in the collision area of the hand and object.
