Cooperative 3D workplace

Field of the invention

The invention relates to the representation of one and the interaction with a

three-dimensional scenario. In particular, the invention relates to a

A display device for displaying a three-dimensional scenario, a three-dimensional scenario displaying device for cooperatively processing the three-dimensional scenario by a plurality of

Operators who use a display device for a

Three-dimensional scenario for cooperative processing of the three-dimensional scenario by a plurality of operators for cooperative monitoring of air spaces and a method for displaying a three-dimensional

Scenarios and a procedure for the cooperative processing of a

three-dimensional scenarios. Technical background of the invention

Stereoscopic systems with individual imaging for one or more users are known. In these stereoscopic systems, individual images for a viewer's left eye and right eye, respectively, are displayed on a screen. In this case, it must be ensured that the respective eye can also recognize only the image intended for this eye in each case, so that the perception of the spatial view created by the viewer differs from the images perceived by the eyes. This separation of the images for the respective eyes of the observer can be done for example by the use of prisms, which break the light so that the eyes look at different images. In addition, it is known to use glasses with differently polarized lenses for the user or viewer. On a display surface correspondingly two different images are displayed with differently polarized light, wherein in each case one lens can only penetrate the correspondingly polarized light to the eye of the beholder. Thus, the impression of a three-dimensional scenario can be evoked in the viewer by different images which rest against his two eyes.

In principle, these two basic design possibilities of a system for the representation of a three-dimensional scenario can also be applied to several

Viewers are chosen. In this case, a second viewer or each additional viewer can easily be allowed to view the three-dimensional scenario, as long as all viewers observe the same scenario. However, if a second viewer is to regard a different scenario than the first viewer, then a display in addition to the two images for the first viewer still have to present two more images for the second viewer. It is not only important to note that each eye looks at the particular image, and only this image, but also that a distinction should be made between the images and the viewer.

Especially when considering a three-dimensional scenario by several observers, the limit of the known stereoscopic shows

Systems in that a display for each additional viewer has to represent two more images. However, any further displayed image on one display reduces the quality of the other images, since the display capacity, such as the resolution, of the display must be divided into several images. Summary of the invention

It may be regarded as an object of the invention to provide a device for displaying a three-dimensional scenario, which enables a cooperative processing of the three-dimensional scenario by a plurality of operators.

In particular, it can be seen as an object of the invention to provide a device for displaying a three-dimensional scenario, which allows scalability of the device to a plurality of users or viewers so that a simultaneous and cooperative interaction of the plurality of viewers with the illustrated three-dimensional scenario without quality loss of the representation can take place and nevertheless each observer has an individual view on the three-dimensional scenario. It is a display device for displaying a three-dimensional

Scenarios, a three-dimensional scenario displaying apparatus for cooperatively processing the three-dimensional scenario by a plurality of operators, and using a display apparatus for cooperatively monitoring air spaces, and a method of displaying and a method for cooperatively processing a three-dimensional one

Scenarios according to the features of the independent claims

specified. Further developments of the invention will become apparent from the

Subclaims and from the following description. Many of the below in terms of the display device and the

Description device described features can also be as

Implement process steps and vice versa.

According to a first aspect of the invention is a display device for displaying a three-dimensional scenario with a first Projection device and a second projection device and a holographic display device with a first holographic unit and a second holographic unit specified. Here are the first

Projection device and the second projection device designed to throw a first image or a second image on the holographic display device. The first holographic unit and the second holographic unit are configured to scatter the first image and the second image, respectively, such that a first eye of one operator perceives the first image and a second eye of the operator views the second image such that the operator Impression of a three-dimensional

Scenarios arises.

The holographic display device may, for example, a display disk and the first and the second holographic unit, for example, a

Be hologram. The first projection device and the second

Projection device may be, for example, laser projectors.

For example, the holograms may be set so that they each receive only the light of one of the two projection devices and direct or scatter in a second direction such that the corresponding image can only be seen from a certain angle. In other words, this means that each hologram is designed to receive incident light only from a predetermined angle of incidence and this light in one

give predetermined angle of reflection. Accordingly, the first projection device is arranged to project light onto the first hologram so that it is below the corresponding one

Incident angle impinges on the first hologram. This also applies analogously to the arrangement of the second projection device and the second hologram. The first holographic unit may be designed to direct the light of the first projection device into a first half-space and the second Holographic unit may be configured to direct the light of the second projection device in a second half-space. A viewer of the holographic display device thus creates the impression of a three-dimensional scenario, wherein a first eye of the observer perceives the first image and a second eye of the observer perceives the second image. Here are the first eye in the first half-space and the second eye in the second half-space.

According to one embodiment of the invention, the display device further comprises a detection unit and an actuator. It is the

Detection unit executed to determine a position of the first eye and the second eye of the operator. The actuator is designed to move the holographic display device such that a viewing direction of the operator in a sagittal plane of the display device strikes the display device perpendicularly.

Since the impression of a three-dimensional scenario arises for the operator in that each eye of the operator sees his own image, it is necessary for one eye each of the operator to be located in the half space assigned to this eye.

Of course, the viewing direction of the operator in the sagittal plane can also hit the display device at any other angle as long as this angle corresponds to the emission direction of the images through the holograms so that each eye can perceive the image assigned to it.

A half space designates a spatial area on the viewing side of the holographic display device, in which only the image of the first

Projection device or the image of the second projection device can be perceived by the eye located in the corresponding half-space. The arrangement of the first half-space and the second half-space is predetermined by the arrangement of the eyes of the operator, whereby the first half-space and the second half-space are horizontally offset from each other, so that in each case an eye of the operator is in the first half-space and the second half-space ,

The first holographic unit and the second holographic unit may be designed such that a positioning of the first half-space and the second half-space depending on an eye distance between the first eye and the second eye of the operator and / or in dependence of a distance of the operator from the holographic Display device is adjusted.

In particular, in a horizontal or lateral movement of the operator with respect to the holographic display device, it may happen that at least one eye from the provided for this eye half-space

moved out and so the impression of a three-dimensional scenario is disturbed.

In other words, this means that the first eye and the second eye of the operator perceive the first image or the second image individually because the first half space and the second half space are offset horizontally as dictated by the horizontal eye distance of the operator is. A change in the viewing position of the operator in the vertical, however, does not cause that one eye moves into the half-space of the other eye.

Vertical movement of the operator may cause the distance from the operator's eyes to the holographic display to change. This may cause the perception of the first image and / or the second image to be disturbed. Accordingly, the

Display device also be moved so that the distance of the eyes of the Operator of the display device remains substantially constant. In other words, this means that the display device can be moved in one direction towards the operator and away from the operator. However, it is also possible for the first holographic unit or the second holographic unit to be designed such that adjustments to the holographic units can be made so that the holographic units adapt to vertical movements of the user and despite perception of the first image and the second image fluctuating distance of the operator's eyes to the display device is made possible.

To improve the ease of use of the display device, the

Holographic display device are rotated by means of the actuator about a vertical axis of the display device so that the eyes of the operator regardless of its horizontal positioning are always in the respective eye assigned half space.

The sagittal plane of the display device is spanned by a

Viewing direction of the operator on the display device and a horizontal axis of the display device. A vertical movement of the eyes of the operator corresponds to a change in the inclination of the sagittal plane with respect to the

Display device in which the sagittal plane rotates about the horizontal axis of the display device. A movement of the operator's eyes in a horizontal direction can cause an eye to leave its assigned half-space, thus spoiling the impression of a three-dimensional scenario. To the

To maintain three-dimensional impression in the operator, now the holographic display device must be rotated about its vertical axis that the extension of the first half-space and the second half-space in Match with the first eye and the second eye of the operator is brought.

In other words, this means that the angle between the viewing direction of the viewer on the display device and the display device remains constant. This angle can be an arbitrary angle, it is crucial that it remains constant in a horizontal movement of the eyes of the operator. Preferably, the viewing direction in the sagittal plane forms a right angle with the display device, i. H. an angle of 90 degrees.

According to a further embodiment of the invention, the detection unit has at least one camera.

The camera may be configured to determine the position of at least one eye of the operator so as to instruct the actuator to move the holographic display to a position, i. to rotate about its horizontal axis, so that the operator perceives the first image with the first eye and the second image of the holographic display device with the second eye. However, the camera can also be designed to follow a clearly identifiable object, which is located, for example, next to one of the operator's eyes. This uniquely identifiable object may be, for example, a sticker with a visual coding feature, such as a bar code.

According to another embodiment, the holographic display device is configured to display a pointing element. In this case, the operator can interact with the three-dimensional scenario by forming a connecting line from the first eye or the second eye of the operator via the pointing element into the three-dimensional scenario. The connecting line can also as Mean value between the two connecting lines from the left eye or right eye on the pointing element are formed in the three-dimensional scenario.

The calculated connecting line from an operator's eye to the pointing element can be used to determine which element was selected in the three-dimensional scenario.

According to another embodiment of the invention, the pointing element is placed on the holographic display by the operator

Display device touched with a finger.

For example, the holographic display device may include a

having a touch-sensitive layer, which is executed, a

Determining the touch point of a finger of the operator on the display device.

Similarly, using other techniques for touch-sensitive

Scanning devices such as Frustrated Total Internal Reflection (FTIR) the position of a finger on the holographic display device are determined.

According to another embodiment of the invention, the pointing element is placed on the holographic display device by the detection unit detecting a position of the finger of the operator.

In this case, the detection unit can make the position of the finger in principle analogous to the version of the position of the eye, which has been described in detail above.

The detection unit may comprise a plurality of detection elements, of which a first group of a plurality of detection elements for the Detecting the position of the operator's eyes and a second group of multiple detection elements for detecting the position of the finger of the operator can be performed. The positioning of the pointing element on the display device can also be done by means of an input device such as a so-called computer mouse or a trackball or via a keyboard with control arrows and any other input devices. According to a further embodiment of the invention, the

Display device, a two-dimensional display element which is designed to provide the operator information in graphical and written form. In the displayed on the two-dimensional display element

Information can be any information that can not or must not be presented in the three-dimensional scenario.

For example, if the three-dimensional scenario is an airspace to be monitored with aircraft in it, information on a two-dimensional display element may be displayed on a selected aircraft, such as a vehicle. As speed, altitude, weather data or other data are displayed. The two-dimensional display element may be touch-sensitive.

Thus, the two-dimensional display element makes it possible to provide an operation similar to the interaction with the three-dimensional scenario. According to a further aspect of the invention, a presentation device for a three-dimensional scenario for the cooperative processing of the 3-dimensional scenarios by a plurality of operators, which has a plurality of display devices as described above and below, and wherein each one operator at least one

Assigned to the display device.

The display device thus enables the joint and cooperative processing of a scenario by multiple operators. The can

Display devices spatially separated or adjacent to be arranged. For example, a plurality of display devices on a

Workplace, for example, a table, be arranged side by side and so in addition to the common interaction of the operator with the three-dimensional scenario also allow immediate communication between the operators.

However, the display devices can also be arranged spatially separated from each other and still enable the joint cooperative editing of a three-dimensional scenario. The can

Display devices in different rooms, in different buildings and otherwise be arranged spatially separated from each other. It must only be ensured that all display devices have a connection to a central computing system, which is used for the representation of the

three-dimensional scenarios on the display devices. Of course, each display device via a decentralized

Have computing device, which is designed to control the image projection of the first projection device and the second projection device. In this case, the decentralized computing device may be connected to the central computing system, wherein the central computing system merely performs control and coordination of a plurality of decentralized computing devices. The inventive design of the display devices, it is possible to scale the number of operators as desired. For example, the

Display device for four, eight, twelve or any number of operators to be executed, wherein a parameter for the determination of the number of operators, the complexity and the extent of the monitored

three-dimensional scenarios.

A central computer system controls the display devices in such a way that every operator gets the impression of a three-dimensional scenario.

The display device according to the invention can, for example, for the cooperative mission planning of land, water and air vehicles, a joint mission implementation of several unmanned land, water and air vehicles by the respective vehicle operator, the cooperative monitoring of airspaces or national borders or even for the

Monitor events with mass audiences, such as in

Football or concert stages are used.

Depending on the personnel requirements for the task to be performed, a display device according to the invention can be extended so that each operator is provided with one or more display devices. The central computing system controls the distributed to the individual display devices representations or

Display sections so that the operators work on the three-dimensional scenario together and cooperatively.

Of course, one as described above and below

Presentation device can also be used for training and evaluation purposes. According to one embodiment of the invention, each operator sees that

three-dimensional scenario from a real perspective. This corresponds to the real perspective of a perspective of the operator on the three-dimensional scenario corresponding to a position of the operator at the

Display device. In the case of airspace monitoring by, for example, four operators, the real perspective corresponds to the three-dimensional scenario, i. H. which to

supervisory airspace, that viewpoint, as if the operators were positioned relative to the supervisory airspace as positioned relative to the three-dimensional scenario of the airspace.

In other words, for example, one of four operators uniformly distributed around the display device refers to the three-dimensional scenario from an easterly direction, a second operator from a southward direction, a third operator from a western direction, and a fourth operator from a northward direction the three-dimensional scenario of the airspace to be monitored looks.

According to another embodiment of the invention, each operator sees the three-dimensional scenario from a cloned perspective.

The cloned perspective corresponds to a given perspective of the operator on the three-dimensional scenario. In particular, all or even a predefinable part of the operator can view the three-dimensional scenario from the same perspective.

For example, in the event of heavy aircraft traffic in the area to be monitored by it, an operator can be assisted by a second operator by giving the same to both operators on their display device

Perspective on the three-dimensional scenario is mapped. According to another embodiment of the invention, each operator sees the three-dimensional scenario from an individual perspective.

The individual perspective corresponds to a perspective view of the three-dimensional scenario that can be set as desired by each operator. In other words, this means that an operator can adjust his perspective as if he were moving freely in the space shown.

Just as the operator can change a perspective on the three-dimensional scenario, the operator may select and enlarge an area of the three-dimensional scenario, for example, to obtain increased detail of the presentation.

According to a further embodiment of the invention, each operator is assigned a second display device which is executed

three-dimensional representation of a spatially distant

Communication partner.

In particular, in connection with spatially distributed display devices, an operator of a remote display device can also be represented here.

According to another aspect of the invention, the display device is described above and below for cooperative monitoring of

Airspaces used.

In accordance with another aspect of the invention, a method for representing a three-dimensional scenario is provided.

In one step, a respective first image and a second image are projected onto a respective holographic display device from one Variety of holographic display devices, so that the impression of a three-dimensional scenario arises in a viewer of the three-dimensional display device, each holographic display device the

represents a three-dimensional overall scenario from a specific perspective.

In a further step, the detection of an eye position of the

Beholder.

In a further step, the holographic display device is rotated about a vertical axis so that a viewing direction of the viewer in one

Sagittal plane of the display device falls at a predetermined angle to the holographic display device.

According to another aspect of the invention, a method for cooperatively processing a three-dimensional scenario is provided.

In one step, the detection of an eye position of a viewer of the three-dimensional overall scenario takes place. In a further step becomes a reference point on the holographic

Indicator set.

In a further step, a connecting line is calculated from the eye position via the reference point into the three-dimensional overall scenario.

Then, the determination of an object targeted by the observer takes place in the overall three-dimensional scenario.

Detailed description of embodiments

The illustrations in the figures are schematic and not to scale.

If the same reference numerals are used in the following description of the figures, these relate to the same or similar elements.

Fig. 1 shows a display device 100 according to an embodiment of the invention. The display device has a first projection device 111 and a second projection device 1 12, as well as a holographic

Display device 130 with a first holographic unit 131 and a second holographic unit 132. The first projection device 11 1 is designed to project an image onto the first holographic unit 131, the image of the first holographic unit 131

Projection device is directed in the direction of a first eye 121 of an operator and the image of the second projection device 1 12 is directed by the second holographic unit 132 in the direction of a second eye 122 of an operator.

The different images perceived by the first eye and the second eye give the operator the impression of a three-dimensional scenario.

Furthermore, FIG. 1 shows a first half space 151 and a second half space 152, in which the first eye or the second eye can be located, without the impression of a three-dimensional scenario being disturbed. Only when leaving the first half-space or the second half-space through the first eye or the second eye, this impression is disturbed. Furthermore, the first half space and the second half space are limited by the fact that a vertical movement of the operator changes a distance of the operator's eyes from the display device, which can also interfere with the perception of the first image and / or the second image. To counteract this effect that the display device are moved toward or away from the user, so that a change in the distance of the eyes of the

Display device is compensated.

Fig. 2 shows a display device 100 according to another

Embodiment of the invention. The display device 100 has a holographic display device 130, an actuator 202 and a detection unit 220.

The detection unit 220 is executed, a position of the operator of

Detect display device. In order to ensure that the operator's eyes perceive different images, giving the impression of a three-dimensional scenario to the operator, depending on the operator's position relative to the holographic display 130, it may be necessary for the holographic display 130 to be about a vertical axis 135 along the directional arrow 136 to rotate so that each eye of the

Operator can perceive the provided for this eye image or that the first eye in the first half-space and the second eye in the second

Half room is located. Fig. 3 shows a holographic display device 130 in isometric

Presentation. A sagittal plane 310 is spanned by a viewing direction 301 of the operator on the display device 130 and a horizontal axis 320 of the display device 130. Thus, the sagittal plane 310 intersects the display device 130 at an angle α 31 1. From the viewing direction 301 in the sagittal plane 310 and the

Indicator 130, the angle ß 321 is clamped.

A change in the angle α 31 1 corresponds to a vertical movement of the operator in front of the display device 130.

A horizontal movement of the operator in front of the display device 130 causes at least one eye to leave the half-space provided for this eye and thus perceive either the wrong image or no image, so that the impression of the three-dimensional scenario is disturbed. To give the impression of a three - dimensional scenario independent of a movement of the Operator is maintained, the holographic display device 130 is moved by the actuator 202 so that the angle ß 321 constantly maintains a predetermined value. 4 shows a display device 100 according to another

Embodiment of the invention. The display device has a

holographic display device 130, a two-dimensional display element 430, a second holographic display device 230 and four cameras 221, 222, 223, 224, which represent the position detection unit of the operator's and / or the operator's finger.

The cameras can be designed to determine a positioning of the finger on the display device, but also to determine a positioning of the finger in the room.

Both the first display device 130 and the second display device 230 may be rotated about their respective vertical axis by an actuator (not shown) such that a viewing direction 301 falls on the display device 130 and the display device 230 at a constant predeterminable angle.

5 shows a side view of a holographic display device 130 and a schematically represented three-dimensional scenario 550. The

Display device 130 is configured to display a pointing element 510.

In order to enable an interaction of the operator with the three-dimensional scenario, the pointing element 510 is movable on the display device 130. This can be done for example by touching the display device 130 with a finger or for example by movement or actuation of an input element, such as a so-called. Computer mouse. In order to recognize the selected area 555 in the three-dimensional scenario, a connecting line 51 1 is formed by the operator's eye 121, 122 via the pointing element 510 into the three-dimensional scenario 550. On the basis of the connecting line 51 1, the operator-selected element 555 can be determined in the three-dimensional scenario.

The selected element 555 may be a single object or part of an object in the three-dimensional scenario.

For example, a vehicle, such as an aircraft, or any part of the vehicle, such as a wing or a rudder, may be selected.

The connecting line 51 1 corresponds to the viewing direction 301 of the operator on the display device 130, whereby the connecting line 51 1 and the

Indicator 130 includes the angle α 31 1. As already stated, a change in the angle α does not influence the impression of the perception of a three-dimensional scenario by the operator. Also, without affecting the three-dimensional perception by the operator, a change in the angle γ 501 between the display device 130 and a horizontal line 502, for example, the surface of a table.

FIG. 6 shows a three-dimensional scenario display device 600 for cooperatively processing the two-dimensional scenario by a plurality of operators according to an embodiment of the invention. There are four display devices 100 at a workstation, such as a table 502 arranged. In this case, each display device is assigned an operator 120 in each case.

Each operator 120 looks at the display device 100 assigned to it, so that each operator is given the impression of a three-dimensional scenario. From the operator 120's perspective, the situation is that the operators a virtual three-dimensional overall scenario 610

consider.

It should be noted that the overall virtual three-dimensional scenario is only visible when the operators view their assigned or any display device 100.

The display device shown in FIG. 6 thus enables the joint cooperative processing of a three-dimensional overall scenario by a plurality of operators, wherein the processing of the three-dimensional scenario can be assisted by providing the operators with an immediate

Communication and coordination with each other is made possible.

FIG. 7 shows a method 700 for the representation and cooperative processing of a three-dimensional overall scenario according to an embodiment of the invention.

In a first step 701, a respective first image and a second image are projected onto a respective holographic display device from a multiplicity of holographic display devices, so that the impression of a three-dimensional scenario arises for a viewer of the three-dimensional display device, each holographic

Display device represents the three-dimensional overall scenario from a specific perspective.

In this case, the first image and the second image each of a first

Projection device or a second projection device projected onto a holographic display device. By projecting a plurality of first images and second images onto each one of a plurality of holographic display devices, it is subjected to a plurality of Operator can view the three-dimensional scenario from its own perspective.

Accordingly, an operator's perspective on the three-dimensional scenario is compiled from a pair of a first image and a second image, respectively, which are projected onto the display device assigned to that operator.

The offering of the first image and the second image for the plurality of display devices may be controlled, for example, by a central control system or central computer system. The central control system may be implemented, the various above and below

presented perspective views of an operator on the three-dimensional

Overall scenario.

In this case, each holographic display device, the three-dimensional

Overall scenario from a specific one described above

View perspective. For example, the three-dimensional overall scenario can be represented such that a plurality of display devices which are arranged at a workstation, the three-dimensional overall scenario of a so-called natural

Represent perspective. Thus, for example, four display devices may be arranged at a workstation, so that a first display device shows the three-dimensional overall scenario from a first perspective, for example from the east, a second display device from a second perspective, for example from the south, shows a third display device from one third perspective, for example, pointing west and a fourth Display device from a fourth perspective, for example, north direction shows.

In this case, the perspectives of the operator can correspond to the perspective which the operators have on a miniature image of the user

Three-dimensional overall scenarios would have, if this miniature picture really would be between the operators in the middle of the workplace.

Of course, each display device can show any perspective on the overall three-dimensional scenario.

In a second step 702, the detection of an eye position of the

Beholder. In this case, for example, only the position of an eye, for example the left eye or the right eye, can be detected and closed on the position of the right eye or the left eye of the operator. But it can also be the position of the right eye and the left eye of the operator are detected, so as to meet the individual horizontal eye relief of different operators.

Likewise, the central control system can have an operator identification, by which the position of the second eye is determined after detecting a first eye position by the individual horizontal eye distance known to the central control system.

The detection of the eye position can take place by means of a detection unit, for example one or a plurality of cameras. In this case, the detection of the eye position can take place by means of image recognition. Similarly, the eye position can be detected by a marker is placed at a certain distance and angle to an eye, for example, on the forehead of the operator. About the Detecting the position of the marker, the central control system determines the position of an eye or both eyes of the operator.

In a third step 703, the holographic display device is rotated about a vertical axis so that a viewing direction of the viewer in a sagittal plane of the display device falls on the holographic display device at a predetermined angle.

This ensures that a first eye of the operator always perceives the first image and a second eye always a second image, which is projected onto the holographic display device, so that the impression of a three-dimensional overall scenario arises for the operator.

In particular, the rotation of the display device avoids that an eye of the operator perceives no image or both eyes perceive the same image, which would disturb the three-dimensional impression.

In other words, by rotating the display device about a vertical axis, lateral movement of the operator is compensated, so that the first image and the second image always strike one eye at a time. A vertical movement of the operator is not the same as the

Sideways movement or horizontal movement is capable of disturbing the three-dimensional impression since the horizontal distance of the operator's eyes allows the eyes to perceive different images regardless of the vertical position of the operator.

In a fourth step 704, a reference point is set on the holographic display device. The reference point can be used as a point on the holographic

Display device are set. Then it is a commitment on a level corresponding to the display device, ie by one

two-dimensional positioning. The reference point can also be defined as a point in space. For fixing the reference point, a finger of the operator can be used in particular, which defines the reference point via a touch-sensitive detection layer on the display device.

Likewise, a position of a finger of the operator in the room or on the display device can be determined by means of a detection system. In this case, the finger position can basically be determined by the same method as the detection of the eye position of the operator described above. Likewise, the reference point by movement of a conventional graphical pointing device, such as a so-called computer mouse or a trackball, which is connected to the central control system as an input device, take place. In a fifth step 705, the calculation of a connecting line from the eye position via the reference point into the three-dimensional overall scenario takes place.

The central control system knows the position of at least one eye of the operator, which serves as the first point of the connecting line. Furthermore, the reference point is known, which serves as the second point of the connecting line.

Then, in a sixth step 706, the determination of one of the

Viewers sighted object in the overall three-dimensional scenario. Through interpolation, the connecting line is extended into the three-dimensional scenario, thus identifying an object in this scenario, which is the Has targeted or selected operator, ie to which object the operator has shown.
