1. A device for moving an object across a surface, comprising:
- a bending wave generator including a plurality of structure borne sound generators distributed along an edge of the surface, arranged to generate bending waves in the surface;
a determiner arranged to determine a position of the object on the surface; and
a controller programmed to control the bending wave generator, so that the object approaches a desired position on the surface based on the bending waves;
whereinthe controller is programmed to perform a wave field synthesis and to individually control each of the plurality of structure borne sound generators according to the wave field synthesis to generate an elementary wave, so that the object experiences a resulting component of movement, passing tangentially to the surface, by being carried on surface wave peaks of a wave field at the surface resulting from a superposition of the elementary waves of the plurality of borne sound generators, such that the object moves toward the desired position.

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.
