Abstract: A computer-implemented method for determining a value for at least three setting parameters by means of an input unit in the form of a graphical user interface with an input cursor positionable in an input area is provided. At least two of the at least three setting parameters can be set independently of one another. The method includes determining a position of the input cursor within the input area; determining a coordinate of the position of the input cursor for each particular setting parameter of the at least three setting parameters as a function of a distance in each case of the position of the input cursor from at least one coordinate origin allocated to the particular setting parameter; and determining a value for each particular setting parameter of the at least three setting parameters as a function of the coordinate determined for each particular setting parameter.

Abstract: A microscope control arrangement for operating a focusing device adapted to adjust a relative focus position of an objective in relation to a sample along an optical axis, including a display device configured to display a graphical user interface for receiving a user input and at least one processor configured to control the microscope focusing device and the display device for updating the graphical user interface in response to the user input, wherein the processor is configured to cause the graphical user interface to display a focus control interface including a graphical focus range element indicating a predetermined focus range and a graphical z-position pointer indicating a current z-position within the predetermined focus range, and wherein the graphical z-position pointer is movable along the graphical focus range element responsive to the user input to adjust the relative focus position to the current z-position indicated by the graphical z-position pointer.
