The present invention relates to a process for the identification of standardized industry - and application case of specific free hand instructions, in which a human - machines - interfaces - unit, which is of a computer - a system (it - system) for the data generation of a process-related computer graphic interactive worker guide - system, is used, from which in the free space which is produced and particles detected free hand movements information which can be utilized which are obtained for operation and / or observing a technical process and / or a production plant are used, wherein said method comprises the steps of: to the interactive user guide - system, a technical module as gestures - module is connected for data transmission; the gestures - module, with at least two physical detection units, on the different detection method of spatial user actions interference are based, connected for data transmission; the free hand movements are defined by a learnt gestures - processor of the gestures - module independently of the recognized technology neutral as the instruction set a defined collections of freely hand instructions processed and the data to data processing units of the worker guide - system for the gestures controlled operation and / or observing the industrial process and / or passed on the industrial production plant.
