Abstract
A method, user interface control arrangement, and a computer program product for controlling a stationary user interface in an industrial process control system as well as to such a process control system. The user interface control arrangement obtains a first live video stream from a video camera monitoring an industrial process at a first location, obtains a process control view for the first location, overlays the process control view on the first live video stream and displays the first live video stream with the overlaid process control view on a display of the user interface.

A method for controlling a stationary user interface in an industrial process control system (10), the method being performed by a user interface control arrangement (16) and comprising the steps of:
- obtaining (58) a first live video stream (VS1) from a video camera (32) monitoring an industrial process at a first location (L1),
- obtaining (60) a process control view (PCV) for the first location (L1),
- overlaying (62) the process control view (PCV) on the first live video stream (VS1), and
- displaying (64) the first live video stream with the overlaid process control view on a display (32) of the user interface.
The method according to any previous claim, wherein the video camera (32) has a fixed position at the first location (L1) and the area covered by the video camera is changeable and further comprising determining the area covered by the video camera (32) and determining a process control view corresponding to the covered area, where the process control view that is displayed overlaid on the first live video stream is the determined process control view.
The method according to any previous claim, further comprising obtaining process control data from process control devices at the first location and displaying the process control data in the process control view overlaid on the first live video stream.
A user interface control arrangement (16) for controlling a stationary user interface in an industrial process control system (10), the user interface control arrangement comprising:
- a video obtaining unit (46) configured to obtain a first live video stream (VS1) from a video camera (32) monitoring an industrial process at a first location (L1),
- a control graphics unit (48) configured to obtain a process control view (PCV) for the first location (L1), and
- a user interface control unit (50) configured to overlay the process control view (PCV) on the first live video stream (VS1) and display the first live video stream with the overlaid process control view on a display (36) of the user interface.
A computer program product for controlling a stationary user interface in an industrial process control system (10), said computer program product being provided on a data carrier (80) comprising computer program code (82) configured to cause a user interface control arrangement (16) to, when said computer program code is loaded into at least one device providing the user interface control arrangement,
- obtain a first live video stream (VS1) from a video camera (32) monitoring an industrial process at a first location (L1),
- obtain a process control view (PCV) for the first location (L1),
- overlay the process control view (PCV) on the first live video stream (VS1), and
- display the first live video stream with the overlaid process control view on a display (36) of the user interface.
