A method for producing security elements, security elements, a security document with at least one security element as well as a transfer film with at least one security element, wherein a three-dimensional object is recorded and a surface profile of the three-dimensional object, described by a function F(x,y), is determined, wherein the function F(x,y) describes the distance between the surface profile and a two-dimensional reference surface spanned by co-ordinate axes x and y at the co-ordinate points x and y. A first microstructure is determined in such a way that the structure height of the first microstructure is limited to a predetermined value smaller than the maximum distance between the surface profile and the two-dimensional reference surface, and the first microstructure provides an observer with a first optical perception which corresponds to the surface profile of the three-dimensional object described by the function F(x,y).

A display device includes an electronic paper display and a ground electrode. The electronic paper display is imageable by receiving charges on a charge receiving layer of the electronic paper display. The ground electrode is opposite to the charge receiving layer of the electronic paper display and exposed at an edge of the display device.

A simulator system for use in simulating fabrication or construction comprises a simulation tool with a magnet mounted on a working end, a simulation workpiece comprising a substrate with an alignment location and at least one tool path indicator; and a sensor device with a corresponding alignment location and at least one magnetic sensor. The simulation tool may comprise a pivotable attachment block mounted on a handle. Different welding accessories may be mounted to the attachment block, and the orientation of the attachment block may be altered to simulate a particular type of welding tool.

A simulator system for use in simulating fabrication or construction comprises a simulation tool with a magnet mounted on a working end, a simulation workpiece comprising a substrate with an alignment location and at least one tool path indicator; and a sensor device with a corresponding alignment location and at least one magnetic sensor. When the sensor device is aligned with the simulation workpiece, the sensor device detects the moving magnetic field of the simulation tool and determines a path travelled by the tool with respect to the sensor device. The system can then determine if the path is consistent with simulation performance data, and can provide feedback accordingly. In this system, the simulation workpiece can be formed of inexpensive printed paper that is bent, curved, or folded into shape.
