Abstract
A basic idea of the present application is that in case of determining a position of the object on the surface, it is possible to also use transport mechanisms for the transport of the object on the surface which leads to less reproducible transport movements as the regulation may be executed directly on the basis of the observed movement as compared to the desired movement. Embodiments using compressed air, magnetism and/or bending waves are described.

A system for moving an object which may be magnetically attracted or repelled across a surface, comprising
- a plurality of magnetic coils distributed along the surface controllable separately from each other in order to generate magnetic dipoles with an alignment perpendicular to the surface;
- a first controller that controls the plurality of magnetic coils distributed along the surface in order to approximate the object to a desired position on the surface;
- a determiner that determines a position of the object on the surface including:
- a display, wherein in a direction of view, the surface is in front of the display and the display is between the surface and the plurality of magnetic coils distributed along the surface, and the display is visible through the surface by a viewer;
- a second controller that controls the display such that the display indicates laterally varying information;
- an optical sensor accommodated in or at the object and that optically scans a supporting surface on which a level bottom of the object is supported in order to acquire a scan result with respect to the laterally varying information;
- and
- a secondary determiner that determines the position of the object depending on the scan result.
A method for moving an object which may be magnetically attracted or repelled across a surface by means of a plurality of magnetic coils distributed along the surface which may be controlled separately from each other in order to generate magnetic dipoles with an alignment perpendicular to the surface, the method comprising:
- determining a position of the object on the surface;
- and
- controlling the plurality of magnetic coils distributed along the surface in order to approximate the object to a desired position on the surface;
- wherein the determining a position of the object on the surface comprises:
- controlling a display such that the display indicates laterally varying information, wherein in a direction of view, the surface is in front of the display and the display is between the surface and the plurality of magnetic coils distributed along the surface, the display is visible through the surface by a viewer;
- optically scanning, by an optical sensor accommodated in or at the object, a supporting surface on which a level bottom of the object is supported in order to acquire a scan result with respect to the laterally varying information;
- and
- determining the position of the object depending on the scan result.
A non-transitory computer readable medium including a computer program comprising a program code for executing, when the computer program is executed on a computer, a method for moving an object which may be magnetically attracted or repelled across a surface by means of a plurality of magnetic coils distributed along the surface which may be controlled separately from each other in order to generate magnetic dipoles with an alignment perpendicular to the surface, the method comprising:
- determining a position of the object on the surface;
- and
- controlling the plurality of magnetic coils distributed along the surface in order to approximate the object to a desired position on the surface;
- wherein the determining a position of the object on the surface comprises:
- controlling a display such that the display indicates laterally varying information, wherein in a direction of view the surface is in front of the display and the display is between the surface and the plurality of magnetic coils distributed along the surface, and the display is visible through the surface by a viewer;
- optically scanning, by an optical sensor accommodated in or at the object, a supporting surface on which a level bottom of the object is supported in order to acquire a scan result with respect to the laterally varying information;
- and
- determining the position of the object depending on the scan result.
