An optoelectronic arrangement for the detection of relative movements or relative positions of two objects, which comprises at least three light emitting means as optoelectronic elements, with the light emitting means being arranged on a closed, imaginary first surface which is plane or convex in each site in such a manner that their respective emission means face towards a first inner space which is defined by the first surface. Further, a force and/or moment sensor provided with this arrangement with a first board and a second board, with the first board and the second board being elastically connected with each other and movable relative to one another. Finally, a personal computer keyboard which is provided with such a force and/or moment sensor.
