Method and data presenting device for assisting a remote user to provide instructions

A method for assisting a remote user to provide instructions to a location in an industrial site where a process control system is operated, the method being performed by a data presenting device when being involved in a communication session with a device of the remote user, the data presenting device being moveable from location to location comprising a camera and a projector, the method comprising:

• retrieving or creating a three-dimensional model of the location;
• associating a presentation item to a position in the three-dimensional model, where the presentation item is a remote user generated presentation item comprising instructions and visual indicators;
• receiving camera control commands from the remote user, said camera control commands comprising field of view control commands;
• controlling the camera using the camera control commands comprising controlling the field of view of the camera;
• receiving projector control commands from the remote user, said projector control commands comprising a command to project the presentation item in a presentation area of the projector;
• and
• controlling the projector using the projector control commands comprising controlling the projector to project the presentation item in the presentation area,
• wherein the controlling of the presentation in the presentation area is performed independently of the controlling of the field of view of the camera and comprises controlling the projector to project the presentation item onto a real world position corresponding to the position in the three-dimensional model.

A data presenting device for assisting a remote user in providing instructions to a location in an industrial site where a process control system is operated, the data presenting device being moveable from location to location and comprising:

• a communication interface for providing a communication session with a device of the remote user;
• a camera having a field of view in which images are captured;
• a projector having a presentation area in which presentation items may be presented;
• and
• a control unit configured to retrieve or create a three-dimensional model of the location, associate a presentation item to a position in the three-dimensional model, where the presentation item is a remote user generated presentation item comprising instructions and visual indicators, receive, from the remote user, camera control commands comprising field of view control commands and projector control commands comprising a command to project the presentation item in the presentation area, control the camera using the camera control commands comprising controlling the field of view of the camera and control the projector using the projector control commands comprising controlling the projector to project the presentation item in the presentation area,
• wherein the control unit is configured to control the presentation in the presentation area independently of the control of the field of view of the camera and control the projector to project the presentation item onto a real world position corresponding to the position in the three-dimensional model.

A computer program product for assisting a remote user to provide instructions to a location in an industrial site where a process control system is operated, said computer program product being provided on a non-transitory data carrier comprising computer program code configured to cause a data presenting device being moveable from location to location and comprising a camera and a projector to, when the data presenting device is involved in a communication session with a device of the remote user,

• retrieve or create a three-dimensional model (3DM) of the location;
• associate a presentation item to a position in the three-dimensional model, where the presentation item is a remote user generated presentation item comprising instructions and visual indicators;
• receive camera control commands from the remote user, said camera control commands comprising field of view control commands;
• control the camera using the camera control commands comprising controlling the field of view of the camera;
• receive projector control commands from the remote user, said projector control commands comprising a command to project a presentation item in a presentation area of the projector;
• and
• control the projector using the projector control commands comprising controlling the projector to project the presentation item in the presentation area,
• wherein the control of the presentation in the presentation area is performed independently of the control of the field of view of the camera and comprises control of the projector to project the presentation item onto a real world position corresponding to the position in the three-dimensional model.
