A method for the production control of process sequences which is assisted by indoor tracking in the industrial processing of workpieces in steel and/or sheet metal processing in a production hall, comprising the steps: providing (step 51') multiple transceiver units fixedly installed in the production hall, at least one mobile unit , and one analysis unit , wherein the transceiver units and the mobile unit are designed to send and receive electromagnetic signals and the analysis unit is designed to determine the positions of the mobile unit in the production hall from the propagation times of the electromagnetic signals between the transceiver units and the mobile unit , spatially assigning (step 51A', 51B') the mobile unit to a person by carrying the mobile unit on or close to a hand of the person , determining (step 53') the position of the hand of the person on which the mobile unit is provided by locating the assigned mobile unit with the indoor tracking system , and incorporating (step 55) the determined position of the hand of the person in the production control of the industrial production plant, characterised in that the incorporation of the determined position of the hand of the person in the production control comprises a movement analysis of the movement of the hand of the person which is detected by the mobile unit , wherein signals are generated by making specific gestures with the mobile unit , an assignment of gestures and processes in the production control system is provided, wherein the processes comprise registering a removal process and registering a deposit process, a movement trajectory of the mobile unit is determined by evaluating positions of the mobile unit determined with the indoor tracking system , a gesture is identified in a portion of the movement trajectory , and a process assigned to the gesture is performed. providing (step 51') multiple transceiver units fixedly installed in the production hall, at least one mobile unit , and one analysis unit , wherein the transceiver units and the mobile unit are designed to send and receive electromagnetic signals and the analysis unit is designed to determine the positions of the mobile unit in the production hall from the propagation times of the electromagnetic signals between the transceiver units and the mobile unit , spatially assigning (step 51A', 51B') the mobile unit to a person by carrying the mobile unit on or close to a hand of the person , determining (step 53') the position of the hand of the person on which the mobile unit is provided by locating the assigned mobile unit with the indoor tracking system , and incorporating (step 55) the determined position of the hand of the person in the production control of the industrial production plant, characterised in that the incorporation of the determined position of the hand of the person in the production control comprises a movement analysis of the movement of the hand of the person which is detected by the mobile unit , wherein signals are generated by making specific gestures with the mobile unit , an assignment of gestures and processes in the production control system is provided, wherein the processes comprise registering a removal process and registering a deposit process, a movement trajectory of the mobile unit is determined by evaluating positions of the mobile unit determined with the indoor tracking system , a gesture is identified in a portion of the movement trajectory , and a process assigned to the gesture is performed. <EOS>
