Description

Arrangement and method for communication by means of two visual output devices

The invention relates to an arrangement and a method which facilitates the communication between two people using two visual output devices.

DE 202016000449 U1 shows a communication system 10 with a

Communication server 12 and a network 14, which supports a person in need of removal from the distance. The communication server 12 has a first receiving device 18. The person in need of assistance wears spectacles 28, to which a stereo camera 30 and a lamp 34 are attached and which a second

Receiving device 40, a second transmitting device 42 and a

Acceleration sensor 46 has. In the glasses 28, an optical output device is arranged. The images from the camera 30 in the glasses 28 are on the

Transmitting device 42 in the glasses 28 and the receiving device 18 to the

Communication server 12 transmitted. The communication system 10 may further include a mobile terminal 48 and a stationary computer 52. The user of the computer 52 or the user of the smartphone 48 can then see what the wearer of the glasses 28 sees and what is picked up by the camera 30 and transmitted to the server 12. The user of the computer 52 or the user of the smartphone 48 can acoustically and visually (video phone ie) give the wearer of the glasses 28 a support. In one embodiment evaluates a

Image evaluation unit 20 of the communication system 10 Images of the camera 30

Automatically detects, for example, automatically font or translated user information into another language. It is possible to insert in a spectacle lens

Display the evaluation result.

In US 2016/0216760 A1 a head-mounted display with several

Deformation sensors for detecting the movement of the upper half of the face of the wearer are disclosed, wherein on the head-mounted display a camera, for example by means of a curved support, is fixed such that the camera is aligned on the lower half of the face, which is not covered by the head-mounted display, to also detect the movements of the lower half of the face.

In DE 102014018056 A1 is a virtual reality glasses with a display device as near-eye display for displaying a virtual reality and a

Detecting means for detecting a predetermined head movement of the wearer of the virtual reality glasses disclosed, in which a captured by a camera system camera image of the environment of the wearer is displayed on the display device. For this purpose, the camera system is arranged directly on the virtual reality glasses in the direction of the wearer. After the head has moved, the camera image can also be partially overlaid by the real environment of the virtual environment.

A disadvantage of this virtual reality glasses is that an indication of the real environment in each case only after carrying out the predetermined head movement, such as a pitching motion, carried by the wearer. Thus, another person can not tell if this pitching movement is being executed as approval in a communication or to activate the display.

DE 10201410721 A1 describes a display device, for example a three-dimensional screen or a three-dimensional spectacle, for displaying a virtual reality with a gesture recognition device with two integrated cameras for determining a movement of a hand and a display device, wherein the display device displays a representation of the hand.

DE 202009010719 U1 describes a communication system with a person operating a transmitting station and a person operating a receiving station, wherein the person operating the transmitting station instructs the person operating the receiving station via executable instructions such that the latter uses images of an object recorded with a camera Supporting station supporting, for example, in their purchase decision by transferring the images. DE 202016008297 U1 discloses a computer-based storage medium for

Modification of a three-dimensional virtual objects within a user interface provided in a head-mounted display device.

The object of the invention is to provide an arrangement and a method which facilitate the exchange of messages between two people.

This object is achieved by an arrangement having the features specified in claim 1 and a method having the features specified in claim 24. Advantageous developments emerge from the subclaims, the following description and the drawings.

The arrangement according to the invention comprises

a first visual output device and a second visual output device,

an image transmission device and

a first camera system and a second camera system.

The first visual output device comprises a first presentation device. The second visual output device comprises a second presentation device. Both the first and the second visual output device can be carried by one human each.

Each camera system is capable of producing an image of the real environment of the camera system. The first camera system is positioned or can be positioned so that the image generated by the first camera system completely or at least partially shows a human wearing the first visual output device. Accordingly, the second camera system is positioned or can be positioned so that the image generated by the second camera system completely or at least partially shows a person wearing the second visual output device. The image transmission device is capable of transmitting an image, which has generated the first camera system, to the second visual output device. Accordingly, the image transmission device is capable of transmitting an image, which has generated the second camera system, to the first visual output device.

The respective display device of a visual output device is able to present a representation comprising an image which has been transmitted to this visual output device. The presentation device presents this representation in a form in which a person wearing this visual output device can visually perceive them.

According to the solution, the image transmission device is capable of transmitting images of the real environment that the first camera system has generated to the second visual output device. It is able to transmit images of the real environment which the second camera system has generated to the first visual output device.

The method according to the invention determines how messages are exchanged between a first person and a second person, and is carried out using a solution according to the invention.

The solution according to the invention can be used in a situation in which two people have to exchange messages with each other in order to work together

Task to solve, for example, together to control a technical system or to regulate or monitor or to jointly assess an environmental condition.

In some situations it is not or not possible with sufficient certainty that the two people talk to each other. For example, the two people are in different rooms, and an acoustic barrier, such as a sound-proof wall, may be present between the two people his. Or the ambient sounds superimpose spoken words. Or the two people do not speak a common language.

Even if direct acoustic communication is possible or each person wears a headset and a microphone and can talk to each other in this way, spoken words are often not sufficient to adequately describe a situation over which the two people must exchange messages with each other. Such a situation occurs, for example, on board a surface ship or an underwater ship.

The solution according to the arrangement and the method according to the solution improve the exchange of messages, especially in this situation. The solution according to the arrangement and the method according to the solution can be used in combination with acoustic message transmission, for example by means of a microphone and headphones, or instead of an acoustic communication.

The solution according to the arrangement and the method according to the solution enable the following type of message exchange: The first camera system generates at least one image that shows the first human, and the second camera system generates at least one image that shows the second human. The images from the first camera system are transmitted to the second visual output device, and the images from the second camera system are transmitted to the first visual output device. The first person thus sees images of the second person, and conversely, the second person sees images of the first human being. One person sees the gestures and facial expressions of the other person. These gestures and facial expressions can complement spoken words. It is well known that the risk of misunderstandings between two people is reduced if gestures and facial expressions are added to verbal communication.

These gestures and facial expressions can also take the place of spoken words, for example if the two people do not speak a common language. thanks Of the two visual output devices and the two camera systems, the two people need not be able to see each other visually

To exchange messages.

The first camera system is capable of producing an image of a human wearing the first visual output device. The first camera system and the first output device can be designed such that the first output device can be moved freely relative to the first camera system and in particular the distance and the orientation between the first output device and the first camera system can be changed freely. This becomes a human being who is the first visual

Output device or at least components of this carries on its head, not restricted in its movements by the first camera system. In particular, it is not necessary for this person to carry a camera of the first camera system on his body in addition to the first visual output device.

In one embodiment of the invention, the first display device is capable of generating a first virtual object. The second presentation device is capable of generating a second virtual object. These two generated virtual objects represent the same information, in a form visually perceivable by a human. The first presentation device is able to present a common representation that a person wearing the first visual output device can visually perceive. This common representation includes an image transmitted to the first visual output device and the first virtual object. Accordingly, the second presentation device is able to present a common representation which a person wearing the second visual output device can visually perceive. This shared representation includes an image transmitted to the second visual output device and the second virtual object. The two virtual objects may be the same or different. Even with different virtual objects they represent the same information. In one embodiment, each presentation device generates at least one virtual object in each case and rewards this virtual object together with an image which has been transmitted via the image transmission device to the visual output device. It is possible that at least one presentation device generates a plurality of virtual objects and displays this plurality of virtual objects together with the received image.

By the display device indicates at least one virtual object, the visual output device is able to output information in a form visually perceptible by a human and thus to represent a virtual reality. In the illustrated virtual reality, a variety of information can be displayed. The presentation device represents this virtual reality virtually on a screen or on the retina of a human eye. Because of this

Screen is part of the head-worn visual output device, this screen moves with, when the human moves his head. This feature ensures that the human always has the presented virtual reality in mind.

A visual output device with its own output device camera eliminates the need to switch between a representation of the real environment and a representation of a virtual reality. Such switching may confuse a person carrying the visual output device, particularly when the switching is abrupt or when the human is moving relative to the depicted real environment, but not the virtual reality depicted.

According to the embodiment, the first visual object showing the first one

Displaying means, and the second visual object displaying the second displaying means displays the same information in a human-visually perceptible form. If two people are the two visual

Carrying output devices on their heads, so the two people can visually communicate with each other, namely with the help of the images of the two Camera systems. At the same time the two humans see the two visual ones

Objects and thereby the same information.

In a further development of this embodiment, the solution according to the arrangement additionally comprises a signal transmission device. This signal transmission device is able to transmit a first signal to the first visual output device. It can transmit a second signal to the second visual output device. Both signals contain the information, which is therefore covered by both signals. The first display device is capable of generating the first virtual object depending on the first signal. The second display device is capable of generating the second virtual object depending on the second signal.

This embodiment ensures that the two visual objects are based on the same signal and thus in fact the same information is displayed on both visual output devices.

In one embodiment of this embodiment, the arrangement comprises a sensor. Or the arrangement is in data connection to a sensor. The sensor is capable of measuring a value of a variable magnitude. Furthermore, the sensor is able to generate a signal which depends on the measured value. The signal transmission device is capable of transmitting the generated signal to both visual output devices, preferably at the same time.

According to this embodiment, the measured value which the sensor has measured is transmitted to both visual output devices. Each display device generates a virtual object depending on the received signals. This virtual object shows the same measured value. With the help of the solution

Arrangement, two people carrying the two visual output devices can exchange messages about this reading. It is not necessary for one of the two people to view the sensor or a physical output device that displays the measured reading and read the reading. This is especially important if the sensor is located in a difficult to reach or dangerous area for people.

For example, each virtual object is a virtually replica of the

Reading. It is possible that the representation of the virtual object only then

performed or changed if the measured value is outside a predetermined range. This makes it possible to visually indicate an exceptional operating situation, in particular a danger situation, early. This situation is presented on both layout visual output devices. The people wearing these two visual output devices will be informed of the situation even if an audible warning message can not be heard.

The sensor, whose signal is transmitted to both visual output devices, is for example an active sonar system, a passive sonar system, a

Towed antenna, a radar system, a geoposition receiver, a

Speedometer and / or a wind direction or wind speed gauge, in particular on board a watercraft.

According to the solution, the arrangement comprises a first camera system and a second camera system. In one embodiment, the first visual output device comprises a first output device camera. The second visual output device includes a second output device camera. The first output device camera is capable of producing an image of the real environment of the first visual output device. The second output device camera is capable of producing an image of the real environment of the second visual output device. The first output device camera can be attached to the head of a person, who carries the first visual output device. The second output device camera can be attached to the head of a person, who carries the second visual output device.

Thanks to this configuration, the output device camera is moved when the human is moving or when moving his head relative to his torso. In one embodiment, each visual output device has an output device camera. This output device camera is capable of producing an image of the real environment. The output device camera of a visual output device shows what a human wearing this output device on his head would see if he did not wear the output device. An image of the output device camera can be displayed to the person carrying this output device camera on his head, or to the person carrying the other visual output device of the arrangement on his head. These two embodiments can be

combine. The exchange of messages between the two people is further enhanced when both images from the two camera systems and images from the two output device cameras can be displayed and used to exchange messages.

In a further development of this embodiment, the image transmission device is additionally able to transmit images from the real environment which the first output device camera has generated to the second visual output device. It is additionally capable of transmitting images of the real environment which the second output device camera has generated to the first visual output device.

In a further development of this embodiment, the first presentation device is able to present a representation which comprises an image which was generated by the first output device camera. This representation can be visually perceived by a person wearing the first visual output device. Accordingly, the second display device is able to present a representation with an image which has generated the second output device camera. This representation can be visually perceived by a person wearing the second visual output device.

In one embodiment, an image that has created an output device camera is presented to a human who uses the visual output device with this output device. Camera wears. The presentation device presents this image to a human wearing the visual output device with this display device on its head. Because the human carries the visual output device on his head, the output device moves when the human moves his head together with the output device and thus the presentation device. It is prevented that the different sense organs of this person provide contradictory information, namely, on the one hand, the eyes, which see the image shown, and on the other hand further sense organs that perceive the spatial position, orientation and movement of people in the room.

In this embodiment, the presentation device is capable of displaying an image of the real environment that a human wearing the output device would see if he did not wear the output device. This image of the real environment is generated by the output device camera and follows a head movement of the camera

People who carries the output device. This avoids the risk of human suffering from travel sickness or virtual reality sickness (VR) disease, which can occur especially when a person is moving or standing in a moving, real environment. This may in particular occur aboard a watercraft and assume a shape similar to a seasickness.

A visual output device with an output device camera allows one

Person carrying this output device to make user inputs or interventions on a machine or plant or system. An image of the

Output device camera displays this machine or system or system. The

Presentation device of this visual output device shows this image. It is possible to additionally display a virtual object which displays information in a human perceptible form.

In one embodiment, the first display device can be switched between at least two different modes. In one mode, the Representation presenting the first display device, an image, which has been transmitted from the image transmission device and was generated for example by the second camera system. In the other mode, this presentation includes an image created by the first output device camera. Accordingly, the second display device can be switched between two different modes.

Preferably, the viewing direction of the first output device camera coincides with the standard viewing direction of a human carrying the first visual output device with the first output device camera. Preferably, the viewing direction of the second output device camera coincides with the standard viewing direction of a person carrying the second visual output device with the second output device camera.

In one embodiment, the viewing direction of at least one output device camera coincides with the standard viewing direction of a person wearing the visual output device. For example, the visual output device includes a carrier on which the display device and the output device camera are mounted. The

The output device camera is mounted on the carrier so that it faces away from the human face and faces outward in the standard viewing direction into the real environment. The images provided by the output device camera thus arranged will show the real environment from the same viewing direction from which the human would perceive the real environment if he did not wear the visual output device. As a result, the displayed images from the output device camera even better match the spatial position and movement of the human head. Contradictory information from different sensory organs of humans are prevented with even greater certainty. Prevented is the often perceived as unpleasant impression that a human, the visual

Output device bears, can not see what is in front of him. In particular, it is ensured that the person has the security of recognizing an obstacle when moving in the standard viewing direction. In one embodiment, the image transmission device and / or at least one visual output device comprises an image intensifier. This image intensifier is capable of amplifying an image produced by a camera system or an output device camera. The respective presentation device is able to present an image which has been amplified by the image intensifier.

In one embodiment, the image transmission device and / or at least one visual output device comprises a conversion device. This conversion device is capable of converting an image in the infrared light region into an image in the visible light region. The respective presentation device is able to present an image that has been converted by the conversion device.

In one embodiment, the arrangement comprises at least one input device. The first visual output device and / or the second visual output device is in data communication with the or an input device. It is possible that each visual output device is in data connection with one input device each. The or each input device is capable of detecting an input of a human, in particular a human, who is wearing a visual output device of the device. The presentation device of a visual output device is capable of altering the presentation presented in response to an input acquired with the associated input device. For example, the appearance of a virtual object is changed.

A person wearing the first or second visual output device and the

Input device, can change a presented presentation with an image, without having to serve the visual output device. In particular, the human being can increase or decrease the imaging scale or the brightness of the image

Change presentation. In one embodiment, the input device comprises a

Remote control for the first camera system and / or the second camera system. As a result, a person carrying the first visual output device can change the images that the second camera system generates and which ones to the first visual one Output device and presented by the first display device. Accordingly, a person wearing the second visual output device can change the images from the first camera system.

The input device may comprise, for example, a mouse or a joy stick or a switch or a touchpad. The input device may be configured to detect a head movement of the person, for example by means of a

Localization sensor, motion sensor or acceleration sensor. The input device may also include a visual evaluation unit, which detects a human gesture and derives therefrom a user input of this person, for example by pattern recognition.

In one embodiment, actuation of the input device causes both

Presentation facilities in the presentation presented the same

Make changes, for example, each highlighted a virtual object for the same information or otherwise presented changed. In this way, a person wearing a visual output device can point out to the person carrying the other visual output device a specific piece of information.

This embodiment with the input device allows the two people to communicate acoustically as well as visually without the two humans needing to be within earshot or sight.

In one embodiment, the arrangement comprises a voice recognition device. This speech recognition device recognizes a speech input of a human wearing a visual output device having a speech input unit. The arrangement generates information from the recognized voice input. Both

Display devices each generate a virtual object containing these

Information, ie the object of the speech input, in a visual

represented perceptible form. Each presentation device presents the visual object for voice input along with an image of one Camera system or an output device camera. It is also possible that the voice recognition device recognizes a voice input that was made with the one visual output device. The presentation device of the other visual output device generates a virtual object which depends on the recognized speech input and presents this virtual object together with an image. Both embodiments make it possible to visually represent spoken words, for example a verbal statement or a verbal reference, additionally on the visual output device.

In one embodiment, the first visual output device and / or the second visual output device belong to a communication device.

The or each optically dense space prevents light from penetrating the real environment into the optically dense space.

In one embodiment, at least one visual visual output device encloses an optically dense space in front of the eyes of a human wearing the dispenser. The visual output device prevents light from entering the optically dense space from the real environment. Because an optically dense space is provided, the representation presented is the only visual information for a human being who is the subject carries visual output device. In particular, the visual output device according to this embodiment prevents light impressions from the outside from superimposing on the presentation presented. These light impressions can cause the person to become confused or not recognize certain segments of the presented presentation at all or only badly, or that the eyes become overloaded and fatigue quickly. This unwanted effect can occur, in particular, when the impressions vary greatly or rapidly over time due to changing ambient brightnesses. A presentation device can be designed in such a way that it displays pictures of differing brightness differently.

In one embodiment, a visual output device presents an image from a camera system and / or from an output device camera together with at least one virtual object. Thus, in a common representation, at least one virtual object and thus a virtual reality is overlaid with an image of the real environment.

The or each screen is located in front of at least one eye of a human wearing this visual output device. The presentation device is able to present the representation with the transmitted image from a camera system and / or from an output device camera on this screen.

In one embodiment, at least one visual output device presents a

Representation with an image on a screen, which adjoins the visually dense space. This type of presentation is often perceived by a human as less disturbing or threatening than other types of presentation, for example as a projection on the retina. It is possible that one area of the first screen is used to represent an image of the real environment, and another area to represent the virtual object or objects.

In one embodiment, the visual output device includes a single screen adjacent to the optically dense space and simultaneously positioned in front of both eyes of a human carrying the output device. In a different way

Embodiment, the output device comprises two screens. Each screen adjoins the optically dense space and is positioned in front of each human eye.

The first camera system is capable of producing at least one image of a human wearing the first visual output device. The second camera system is capable of producing at least one image of a human carrying the second visual output device. Preferably, the first person with the first visual output device can move freely relative to the first camera system, the second person with the second visual output device freely relative to the second camera system. Preferably, the arrangement comprises at least one localization device which corresponds to the first camera system and / or to the second camera system.

In one embodiment, the arrangement comprises an image evaluation unit. This image evaluation unit can automatically evaluate an image which was generated by a camera system of the arrangement. By evaluating the image, the image evaluation unit can automatically determine optically detectable attributes of a human being, with this human being being shown in this image. The image evaluation unit is furthermore able to identify a data record for a human, namely in a data memory among a predefined set of data records with information about different people. This data record identifies the image evaluation unit as a function of the ascertained optically detectable attributes. Or the image evaluation unit automatically determines that no record belongs to the person shown in the image. In one embodiment, at least one camera system comprises one

Pattern recognition device or an image recognition device, which is preferably realized with software. This device determines from at least one image, preferably a plurality of images, from the camera system information about a human, which is shown in the images. If the images of the first

In some applications, this person is difficult to recognize, especially in low light conditions. The information obtained is presented to the other person. This reduces the risk that one person will not know with whom he or she is exchanging messages or with another unauthorized person

People exchanges news.

In one embodiment, this information about a person shown in the images is transmitted with visually ascertainable information

compared different people. This information about different people is stored in a database. The different people are

For example, several crew members of a watercraft. Preferably, a unique identification of the human and / or a portrait of the human being without a visual output device is stored in the database. These

Thanks to this configuration, a first person wearing the first visual output device can selectively see the second person carrying the second output device, or himself. This embodiment allows the first person to see and check his own gestures and facial expressions. It is also possible that a display device simultaneously presents images of both camera systems, in one embodiment additionally with virtual objects. The arrangement according to the invention will be explained in more detail with reference to an embodiment shown in the drawings. Hereby show:

1 shows a first person who carries a solution-based visual output device in the form of a first VR glasses and an input device; two digital cameras, an evaluation computer and a localization facility

2 shows a schematic representation of what the VR glasses present to the first person wearing the first VR glasses on the screen.

In the exemplary embodiment, the invention is used on board a manned watercraft, wherein the watercraft may be an overwater vehicle or an underwater vehicle. Two crew members of the watercraft use two solution-based visual output devices of a solution according to the invention. In the exemplary embodiment, each visual output device has the form of a virtual reality glasses (VR glasses). In one embodiment, an Oculus Rift® is used as VR glasses, which is extended in accordance with the solution.

In Fig. 1, a first person M.1 wears a first VR glasses 101. These VR glasses 101 comprise a carrier which comprises a preferably elastic and variable in length tension belt 107 and a frame 106. The tension belt 107 is guided around the head K.1 of the person M.1 and carries the frame 106. The tension belt 107 ensures a secure fit of the VR glasses 101. The frame 106 carries a plate-shaped and preferably flexible holding element 105. In this holding element 105, two camera lenses 103 are embedded, which belong to two digital cameras of the first VR glasses 101. Each digital camera is capable of producing an image of the real environment of VR glasses 101. The viewing direction of each digital camera preferably coincides with the standard viewing direction of the person M.1 who wears the VR glasses 101. The two digital cameras with the lenses 103 form virtually the human's "eyes of reality" and act as the first output device camera of the embodiment.

The signals from the camera lenses 103 are recorded on CCD chips. As a result, optical images which generate the camera lenses 103 can be recorded. A computer 1 15 of a display device is mounted on the frame 106 The computer 1 15 evaluates the signals from the camera lenses 103 and generates an image of the real environment. On the inside of the holding element 105, that is to say on the surface of the holding element 105 facing the human M.1, a screen 21 1 is provided. Fig. 2 shows schematically this screen 21 1 in the viewing direction, in which the human M.1, who wears the first VR glasses 101, on the holding element 105 and thus on the screen 21 1 looks. In one embodiment, two screens 21 1 are provided, namely one screen in front of each human eye M.1. An illustrative device described below is capable of generating images and presenting them to the first human M.1 on these two screens 21 1. The screens 21 1 belong to the display device of the first VR glasses 101.

The signals from the camera lenses 103 are recorded on CCD chips. As a result, optical images which generate the camera lenses 103 can be recorded. A computer 1 15 of the display device is mounted on the frame 106 The computer 1 15 evaluates the signals from the camera lenses 103 and generates an image of the real environment. The computer 1 15 automatically causes this image to be presented on the or each screen 21 1. In one embodiment, the computer 1 15 generates a stereoscopic representation of the real environment in front of the person M.1 who wears the first VR glasses 101, and uses signals from both digital cameras 103 for this purpose. This stereoscopic representation is presented on the screen 21 1 ,

FIG. 2 shows by way of example an image 215 presented on a screen 21 1. In this example, the person M.1 who wears the VR glasses 101 looks at another one People M.2, for example, another crew member of the vessel. The image 215 shows an image with the head K.2 and the upper body of this other human M.2. The other person M.2 wears a second VR glasses 301, which is the same as the first VR glasses 101.

The person M.1 who wears the VR glasses 101 can perceive gestures and the facial expressions of the other person M.2 without having to set down the first VR glasses 101. This allows the two people M.1 and M.2 communicate visually with each other. This visual communication can complement or even replace acoustic communication when acoustic communication is not possible.

The first VR-goggle 101 is opaque, i. it encloses a visually dense space in front of the eyes of the person M.1, who wears the VR glasses 101. This optically dense space is bounded by the holding element 105, in the frame 106 and the head K.1 of the human M.1. In particular, the holding element 105 is configured with the two camera lenses 103 completely opaque. The first VR glasses 101 prevents light from the real environment from entering the optically dense space in front of the head K.1 of the first human M.1.

On the frame 106 or on the holding element 105 of the first VR glasses 101, a receiving device 1 17 is arranged. This receiving device is able to receive signals wirelessly. The computer 1 15 of the display device generates images from these signals, which are then presented on the screen 21 1

Two digital cameras 123 continuously take images of the first human M.1, preferably at a predetermined sampling rate. The two cameras belong to the first camera system 121 of the embodiment. Two actuators 132 are capable of moving the stationary cameras 123. Thanks to these actuators 132, the digital cameras 123 follow a movement of the first human M.1 in space, so that the images from the cameras 123 show the human M.1. A controller 134 controls these actuators 132. In one embodiment, an evaluation unit, not shown, evaluates the images that generate the cameras 123, and thereby determines a movement of the first human M.1. In the embodiment shown in Fig. 1, however, a transmitter 128 is mounted on the frame 106 of the first VR glasses 101. This transmitter 128 continuously transmits position signal. In the simplest case, the transmitter 128 sends a signal which distinguishes the first VR-goggles 101 from all other devices on board the vessel, which also emit signals. A receiver 130 receives the position signals from the transmitter 128. A transmission unit 124 transmits the received position signals to the controller 134. The controller 134 evaluates the received signals and controls the actuator 132 based on the received and evaluated signals. This embodiment allows in many cases with greater certainty that the cameras 123 follow the movements of the first human M.1, even if more people move in the vicinity of the first human M.1.

The first human M.1 visually exchanges messages with a second human M.2. The second person M.2 carries at his head K.2 a second visual output device in the form of a second VR glasses 301. In the embodiment, the second VR glasses 301 is constructed the same as the first VR glasses 101. FIG. 2 shows these second VR glasses 301 from the front-more precisely, an image of the second VR glasses 301 in the image 215, which is presented on the screen 21 1. This standard viewing direction of the second human M.2 and thus the viewing directions of the two digital cameras of the second VR glasses 301 are directed at the viewer. The following components of the second VR glasses 301 can be seen in FIG. 2:

two camera lenses 303 belonging to two digital cameras of the second VR glasses 301,

the computer 315 of the display device of the second VR glasses 301,

a transmitter 328 which transmits position signals,

a receiving device 317, which corresponds to the receiving device 1 17 of the first VR glasses 101. As can be seen in FIG. 1, two stationary digital cameras 123 generate images of the first human M.1 carrying the first VR glasses 101. Thanks to the actuated actuators 132 for the two stationary digital cameras 123 to follow the movements of the first human M.1. An evaluation computer 125 receives signals from the two cameras 123 and generates processed images of the first human M.1. For example, the evaluation computer 125 automatically illuminates or darkens the images to compensate for excessive variations in the brightness of the images. A transmitter 127 automatically transmits these processed images.

In one embodiment, a transmitter (not shown) transmits the processed images, which the first camera system 121 has produced, directly and wirelessly to the second VR glasses 301, which the second person M.2 carries. In another embodiment, the evaluation computer 125 transmits the processed images to a central computer 220, preferably wired via the electrical system of the watercraft. The central computer 220 is connected to a transmitter 127. This transmitter 127 then transmits the images wirelessly to the second VR glasses 301. In both embodiments, the receiving device 317 of the second VR glasses 301 receives the transmitted signals with the processed images from the first human M.1.

Conversely, the second human M.2 carrying the second VR glasses 301 is shown the rendered images from the cameras 123 showing the first human M.1. Thus, the second human M.2 is enabled to perceive gestures and facial expressions of the first human M.1 without having to discard the second VR glasses 301.

Conversely, several stationary digital cameras (not shown) follow the movements of the second person M.2. These images of the digital cameras show the second human M.2 and are sent directly or via the central computer 220 to the first woman 101 submitted. The receiving device 1 17 of the first VR glasses 101 receives these processed images. The first display device with the computer 1 15 presents the received images on the one screen or the two screens 21 1. Fig. 2 shows schematically how the first human M.1 on a screen 21 1 sees the second human M.2.

On board the vessel a sonar system with an underwater antenna (not shown) is arranged. This sonar system aims at a sound source that emits sound waves under water, and in particular determines the direction and / or the distance from the vessel to this sound source. This sonar system generates signals depending on the measured values (e.g., direction and distance, and sound intensity as a function of time and / or frequency). These signals are transmitted via the wired electrical system of the vessel to the central computer 220. With the aid of the transmitter 127, the central computer 220 transmits these signals with measured values of the sonar system at the same time to the two receiving devices 17 and 317 of the two VR glasses 101 and 301, for example with local radio.

Preferably, the receiving device 1 17 receives the signals at a fixed frequency. The computer 1 15 of the first display device evaluates the received signals and generates virtual objects in the form of virtual instruments 213. The computer 1 15 of the first display device generates a common representation, which simultaneously the image 215 of the real environment, which shows humans M.2, and presents several virtual objects in the form of virtual instruments 213. The receiving device 317 of the second VR glasses 301 receives the same signals at the same frequency. The computer 315 of the second display device evaluates the received signals and also generates virtual objects in the form of virtual instruments. The virtual instruments shown on the screen 21 1 of the first VR glasses 101 show the same information as the virtual instruments on the screen of the second VR glasses 301, and can be graphically constructed the same or constructed graphically different his. It is possible that a person M.1, M.2 changes the virtual instruments shown, for example enlarged or reduced.

Preferably, the computer 1 15 updates the virtual instruments 213 at the frequency at which the receiving devices 17 and 317 receive the signals. In one embodiment, the or at least some signals contain presentation information. If a measured value is outside a predetermined range, for example, if the distance to a sound source falls below a predetermined barrier, then the corresponding virtual instrument 213 on the screen 21 1 of the first VR glasses 101 and the corresponding virtual instrument on the screen of the second VR glasses 301 highlighted. As a result, the attention of the human M.1 is directed to this virtual instrument 213 for a relevant measurement. The same goes for the second person M.2.

In the exemplary embodiment, the person M.1 uses the human M.2, for example, because the crew member M.2 has previously addressed the crew member M.1. The human M.1 sees on the screen 21 1 on the one hand an image 215 which shows the human M.2, and on the other hand the virtual instruments 213, cf. 2. The human M.1 can thereby perceive the measured values from the sonar system, which are displayed with the aid of the virtual instruments 213, and at the same time communicate visually with the human M.2.

The two humans M.1 and M.2 see the same information (the same measurements from the sonar system), represented by virtual instruments. The virtual instruments are presented to the two humans M.1 and M.2, each in a common representation together with an image of the other human M.2 or M.1. The common presentation, which is presented to the human M.1, shows the virtual instruments 213 and an image of the second human M.2, cf. Fig. 2. Conversely, the common representation presented to the human M.2 shows the virtual instruments for the same measurements and an image of the first one People M.1. Both the images of the humans M.2, M.1 and the virtual instruments are constantly updated.

As provided, the first human M.1 carries an input device 109 in his left hand. The second human M.2 carries a corresponding input device (not shown). For example, the human M.1 operates a button or button or a touch-sensitive panel on the input device 109. Or, the input device 109 has a motion sensor or an acceleration sensor that registers a certain left-hand movement.

With the aid of the input device 109, the first human can select a virtual instrument 213 in the common representation on the screen 21 1. This selection is transmitted by a transmitter 136 of the first VR glasses 101 to a receiver (not shown) of the central computer 220. In one embodiment, the transmitter 136 is mounted on the input device 109. This selection and highlighting are communicated to the second VR glasses 301. The second human M.2 also sees in the common representation the virtual instrument 213 highlighted, which the first human M.1 has selected with the aid of the input device 109. The first human M.1 can visually give explanations of the emphasis, for example, with gestures that the second human M.2 sees on the screen of the second VR goggles 301.

It is possible that the two people M.1, M.2 additionally each carry a voice input unit, for example a microphone, and a voice output unit (not shown). The voice output unit that the first human M.1 uses may be integrated into the frame 106 or the straps 107 of the first VR glasses 101. Accordingly, the voice output unit using the second human M.2 may be integrated with the second VR glasses 301. Thanks to the speech input units and the speech output units, the two people M.1 and M.2 can additionally communicate acoustically with one another, even if considerable ambient noise makes acoustical communication without aids difficult. In particular, a Human verbal information on the virtual object just that he or she has previously selected.

By way of example, the first human M.1 can select a virtual instrument 213 with the aid of the input device 109 and point the second human M.2 to the displayed sensor value. By gestures and / or by an acoustic instruction, the first person M.1 can instruct the second human M.2 to perform a certain action.

As already explained above, two camera lenses 103 of two digital cameras are embedded in the holding element 105 of the first VR glasses 101. In the holding member 305 of the second VR glasses 301 two camera lenses 303 are embedded. The viewing direction of each digital camera preferably coincides with the standard viewing direction of the person M.1 who wears the VR glasses 101. The two digital cameras with the lenses 103 virtually form the "eyes of the reality" of the human being.These two cameras with the lenses 103 virtually form the "eyes of the reality" of the human being. For they show the real environment of the first human M.1. In one embodiment, the first human M.1 can switch between two different representations, which are optionally presented:

a representation showing the second human M.2 and constructed as shown schematically in Fig. 2, and

- A representation that shows the real environment of the first person M.1, that is, what the first person M.1 would see in an area in front of himself, if he would not wear the first VR glasses 101.

The first person M.1 can choose the representation with the real environment in front of the first person M.1 himself, if he does not communicate with a second person M.2, or if he wants to move and make sure that he is not against an obstacle running. In these two representations, the virtual instruments 213 are displayed, so that the first person on the screen 21 1 always a common representation. Accordingly, the second human M.2, who wears the second VR glasses 301, can choose between the following two representations:

a representation produced by the stationary cameras 123 and showing the first human M.1 and constructed according to the representation which is shown schematically in FIG. 2, and FIG

a representation showing the real environment of the second human M.2, that is, what the second human M.2 would see in an area in front of himself if he did not wear the second VR goggles 301.

In one embodiment, the first VR glasses 101 can transmit to the central computer 220 the images of the real environment which the two cameras have produced with the lenses 103. The central computer 220 transmits these images via the transmitter 127 to the second VR glasses 301. The second human M.2 can therefore choose between three representations:

a representation produced by the fixed cameras 123 and showing the first human M.1

a representation showing the real environment of the second human M.2, that is, what the second human M.2 would see in an area in front of himself if he did not wear the second VR glasses 301, and

The first human M.1 can thus show the second human M.2 something that is in front of the first human M.1, for example a machine or a facility aboard the watercraft. Accordingly, in one embodiment, the first human M.1 can likewise select between three representations. In all three representations, the virtual instruments 213 are preferably faded in each case.

In some situations, a person M.1, M.2 may consider it disadvantageous that he sees in the image the other human M.2, M.1 only with VR glasses 101, 301 in front of his eyes. The following embodiment offers a possible remedy for this Problem. In one embodiment, a set of data records is stored in a database. Each record relates to each crew member of the vessel and preferably includes an identifier, a portrait, and a plurality of optically recordable attributes of that crew member, the portrait showing the crew member without a visual output device. An image evaluation unit automatically searches in the images of a human M.1, M.2, which were generated by the first or second camera system for optically detectable attributes of this person the image evaluation unit searches in the database for a record, the appropriate optical detectable attributes and thereby determines the crew member shown in the images. The image evaluation unit determines the portrait of this crew member and transmits this portrait to the visual output device, which is worn by the other person. On one screen, the display device of this other visual output device displays the portrait. It is also possible that the image evaluation unit determines that no data record contains suitable optically detectable attributes.
