    Fig. 2 schematically illustrates, in terms of a number of functional units, the components of a portable holographic display device 11, 12 according to an embodiment. Processing circuitry 21 is provided using any combination of one or more of a suitable central processing unit (CPU), multiprocessor, microcontroller, digital signal processor (DSP), application specific 10 15 20 25 30 integrated circuit (ASIC), field programmable gate arrays (FPGA) etc., capable of executing software instructions stored in a computer program product 31 (such as illustrated in Fig. 3), eg in the form of a storage medium 23. The storage medium 23 may also comprise persistent storage, which, for example, can be any single one or combination of magnetic memory, optical memory, solid state memory or even remotely mounted memory. For example, the storage medium 23 may store a computer generated model of the process plant 13.

    Particularly, the processing circuitry 21 is con Gured to cause the portable holographic display device 11, 12 to perform a set of operations, or steps, A102-S120. These operations, or steps, S102-S120 will be disclosed below.
    For example, the storage medium 23 may store the set of operations, and the processing circuitry 21 may be con Gured to retrieve the set of operations from the storage medium 23 to cause the portable holographic display device 11, 12 to perform the set of operations.

    Fig. 3 shows one example of a computer program product 31 comprising computer readable means 33. On this computer readable means 33, a computer program 32 can be stored, which computer program 32 can cause the processing circuitry 21 and thereto operatively coupled entities and devices , such as the communications interface 22 and the storage medium 23, to execute methods according to embodiments described herein. The computer program 32 and / or computer program product 31 may thus provide means for performing any steps as herein disclosed.
    In the example of Fig. 3, the computer program product 31 is illustrated as an optical disc, such as a CD (compact disc) or a DVD (digital versatile disc) or a Blu-Ray disc. The computer program product 31 could also be embodied as a memory, such as a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM), or an electrically erasable programmable read- only memory (EEPROM) and more particularly as a non-volatile storage medium of a device in an external memory such as a USB (Universal Serial Bus) memory or a Flash memory, such as a compact Flash memory. Thus, while the computer program 32 is here schematically shown as a track on the depicted optical disk, the computer program 32 can be stored in any way which is suitable for the computer program product 31. 10 15 20 25 Fig. 4 is a ow chart illustrating embodiments of methods for displaying process information on a portable holographic display device 11. The methods are performed by the portable holographic display device 11. The methods are advantageously carried out by means of computer programs 32.
    Reference is now made to an embodiment for displaying process information on a portable holographic display device 11 as performed by the portable holographic display device 11 as illustrated in Fig. 4. Parallel references are made to the process control system 10 of Fig. 1 and the embodiments of the portable holographic display device 11 rendering a three-dimensional holographic image in Figs. 5 and 6.
    The portable holographic display device 11 is con Gured to, in a step S104, acquire process information related to a process plant 13.
    The portable holographic display device 11 is con Gured to, in a step S106, determine how to display the process information.
    The portable holographic display device 11 is con Gured to, in a step S108, render a three-dimensional holographic image 50, 60 of the process information on a display 24 of the portable holographic display device 11 according to the determination.
    Hence, this involves integrating a holographic display 24 with a portable holographic display device 11 for interacting with a control system (e.g. 800xA® by ABB) of a process plant 13 and / or at least one other portable holographic display device 12.
    Human operators working independently could display a hologram of the process plant 13 to obtain a three-dimensional impression of the status of components. In addition a human operator can contact another human operator and obtain a hologram of that human operator which provides a more connected experience for the human operators.
    F ig. 5 shows a Rst example of how a three-dimensional holographic image 50 representing process graphics could be displayed on a portable 10 15 20 25 holographic display device 11. F ig. 6 shows second example of how a three-dimensional holographic image 60 representing a human operator could be displayed on a portable holographic display device 11.
    In general terms, rendering is herein de Ned as the process of generating a three-dimensional image from a three-dimensional representation (or model, in what collectively could be called a scene Le), by means of the processing circuitry 21.
    Reference is continued to the made to Owchart of Fig. 4 for methods for displaying process information on a portable holographic display device 11 as performed by the portable holographic display device 11 according to further embodiments.
    There may be different examples of when in time the portable holographic display device 11 is to acquire the process information in step S104.
    According to an embodiment the portable holographic display device 11 is con Gured to, in a step S102, receive user input identifying the process plant 13. This input (or the reception thereof) may act as a trigger for the portable holographic display device 11 to acquire the process information, as in step S104. Hence the process information may be acquired in response to receiving the user input identifying the process plant 13.
    There may be further different examples of how the portable holographic display device 11 acts once it has acquired the process information related to the process plant 13. For example, the portable holographic display device 11 may share the three-dimensional holographic image 50, 60 with another the portable holographic display device 12. Particularly, according to an embodiment the portable holographic display device 11 is con gured to, in a step S110, transmit an encoded version of the three-dimensional holographic image 50, 60 to at least one other portable holographic display device 12.
    How to encode a three-dimensional holographic image is as such known in the art and further description thereof is therefore omitted. 10 15 20 25 30 10 The portable holographic display device 11 may further receive a three-dimensional holographic image from another portable holographic display device 12. Particularly, according to an embodiment the portable holographic display device 11 is con Gured to, in a step S112, receive an encoded version of another three-dimensional holographic image from another portable holographic display device 12. The portable holographic display device 11 may then be con Gured to, in a step S114, decode the received three-dimensional holographic image. How to decode an encoded three-dimensional holographic image is as such known in the art and further description thereof is therefore omitted. The portable holographic display device 11 may then be con Gured to, in a step S116, render a three-dimensional holographic image of this decoded three-dimensional holographic image.
    Information could be pulled into the hologram to be shared among human operators and discussed around for improved problem solving. Therefore, according to an embodiment the portable holographic display device 11 is con Gured to, in a step S118, receive an indication of further data. This further data may represent information that could be pulled into the hologram to be shared. Therefore, according to this embodiment the portable holographic display device 11 is con Gured to, in a step S120, incorporate the further data in the three-dimensional holographic image 50, 60. There may be different examples of from where the indication may be received. For example, the indication may be received as user input or from another portable holographic display device 12.
    There may be different examples of process information. For example, the process information may represent process graphics, trend data of the process plant 13, a human operator of the process plant 13, or any combination thereof. In this respect, Fig. 5 schematically illustrates a portable holographic display device 11, 12 rendering a three-dimensional holographic image 50 representing process graphics and comprising a first three-dimensional holographic image object 51 and a second three-dimensional holographic image object 52. Further, Fig. 6 schematically illustrates a portable holographic display device 11, 12 rendering a three- 10 15 20 25 11 dimensional holographic image 60 representing a human operator and comprising a single three-dimensional holographic image object 61.
    There may be different ways for how the portable holographic display device 11, 12 may acquire the process information. For example the process information may be acquired from an image capturing unit 25. For example the process information may be acquired from a computer generated model of the process plant 13. As noted above, the storage medium 23 of the portable holographic display device 11, 12 may store such a computer generated model of the process plant 13. Additionally or alternatively, the portable holographic display device 11, 12 may acquire such a computer generated model of the process plant 13 from the process plant 13 or from another portable holographic display device 11, 12. Yet alternatively, the portable holographic display device 11, 12 may acquire such a computer generated model of the process plant 13 from an entity, such as a server, in the network 14.
    The present invention could be used in a plurality of scenarios. Three such scenarios are brie Y summarized next.
    According to the first scenario the present invention could be used to efficiently monitor and understand the control process of the process plant 13 by improving spatial-temporal reasoning for improved decision making.
    According to a second scenario the present invention could be used to enable effective communication between human operators that are working remotely to foster a sense of teamwork.
    According to a third scenario the present invention could be used to enable sharing of information between human operators (i.e., to provide the ability for human operators to point to and show information for discussing around, etc.) to promote collaboration. 12 The inventive concept has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the inventive concept, as defined by the appended patent claims.
