Display apparatus for an emergency service member for displaying information content of different information types from a guidance system

0001The present invention relates to a display device for an emergency worker for displaying information content of various types of information in a guidance system. The present invention also relates to an arrangement with a guide system for guiding a plurality of emergency services and a plurality of display devices.

0002For example, clocks are known as display devices via which an information system or guidance system can transmit information to a user of the clock. However, such a watch as an information receiver has the disadvantage that the user of the watch has to direct his attention to the watch in order to receive the information presented by the watch. This allows the user to be distracted from other activities or tasks, in particular during an assignment. The responsiveness of the user when looking at the watch to receive the information is also disadvantageously reduced.

0003The document <patcit id="pcit0001" dnum="WO0231578A1"><text>WO 02/31578 A1</text></patcit> shows an information system with a signal detection device that detects signals reflected back from at least one eye having a retina, with an output device that provides information in cooperation with an information device and as a function of the detected signals, the output device comprising a scanning projection device that at least some of the information is projected onto the retina. In this case, the signal acquisition device comprises a scanning scanning device which, in a first scanning process, carries out an at least partial acquisition of a retinal reflex image of the retina and, in a later scanning process, undertakes a less extensive acquisition of the retinal reflex image.

0004The document <patcit id="pcit0002" dnum="US2015061974A1"><text>US 2015/061974 A1</text></patcit> shows a head-mounted display that enables a user to visually recognize a virtual image and an external scene.

0005According to a first aspect, a display device for an emergency worker for displaying information content of various information types of a guidance system is proposed. The display device comprises a display that can be worn by the emergency worker and has a plurality of visually distinguishable segments, each of the segments being assigned at least one of the information types, the respective segment for the visual output of a current information content of the information type assigned to the segment is set up. Furthermore, the display device comprises a control unit, which can be coupled to the guidance system, for controlling the display. The display device is designed as a mask which can be worn in front of the face of the emergency worker, the visually distinguishable segments being arranged in a peripheral field of vision of the emergency worker when the mask is worn by the emergency worker. Alternatively, the display device is designed as glasses or glasses extension that can be worn by the emergency worker, the visually distinguishable segments being arranged in a peripheral field of view of the emergency worker when the glasses or the glasses extension are worn. A number of the segments of the plurality of visually distinguishable segments are set up to map an area outside of the operator's visual image, in particular an area behind the operator, by means of the visual output of the information content of the information types assigned to the segments of the number.

0006The information types include, for example, one or more navigation points, one or more navigation areas, one or more threats to the emergency services, predetermined goals and / or active assignments by the guidance system, red force tracking and / or blue force -Tracking. The different types of information are preferably assigned different colors in the visual representation by the segments.

0007The visually distinguishable segments are in particular visually distinguishable for the emergency services, that is to say for a human user. The individual segments of the display can preferably be controlled individually by the control unit.

0008If, for example, an information type is a threat and the threat is in the left area of ​​the field of vision of the emergency services, a segment in the display in the left area that is assigned to this information type will light up red. This signals to the emergency responder, in particular in his peripheral field of vision, by the current information content of the red light in the segment, that there is a threat to the left in front of him.

0009The present display device significantly increases the effectiveness of the emergency personnel during an operation, since it is possible to provide current information content of various types of information from the guidance system to the emergency personnel via the display. The present display device supports the emergency worker through peripheral perception with minimal restriction of the emergency worker. The proposed display device can also accelerate the command process and the control process between the guidance system and the emergency services.

0010The display of the display device and the control unit of the display device can be produced inexpensively, are energy-efficient and are only light in weight for the emergency services.

0011The display is preferably designed as a display that can be worn on the head of the emergency responder.

0012The control unit can be coupled or connected to the guidance system in particular via one or more communication links.

0013In particular, the control unit can be coupled to the control system via at least two separate, independent communication links to create redundant communication lines. Examples of a communication standard that can be used for this purpose include GPRS, UMTS, LTE, WLAN, Bluetooth, TETRA radio, LoRa and ZigBee.

0014The task force is, for example, a soldier. Further examples of emergency services are fire fighters, police officers, THW employees and the like.

0015The management system can also be referred to as a control center or information system. The display can also be referred to as a segment display.

0016According to one embodiment, the control unit is set up to receive signals having the current information content for the information types from the guidance system and to control the display by means of control commands generated as a function of the received signals for the visual output of the current information content .

0017The display device can use the signals to receive the current information content for the various types of information from the guidance system. The control unit then controls the display accordingly so that all information content received, in particular in real time, is displayed to the user via the segments of the display.

0018According to a further embodiment, the control unit is set up to assign the information types to the segments of the display.

0019The control unit can advantageously control the assignment of the respective information type to the segments. If, for example, the position of a threat changes relative to the emergency worker, the control unit will map the threat information type to a change in the assigned segment in accordance with this change in location. That is, if the threat moves, for example, from a left area relative to the emergency worker into a central area relative to the emergency worker, the control unit will move the segment assigned for the threat information type from a left area of ​​the display to a central one Change the area of ​​the display.

0020According to a further embodiment, the control unit is also set up to determine a display type for the respective information type assigned to one of the segments.

0021For example, the control unit in this embodiment is set up to change a color and / or a pulse duration of the segment in the context of determining the display type. For example, if the information type represents a threat, the control unit can determine the color red for the information type. If the threat to the emergency services comes closer, the control unit can determine that the red illuminated segment is also pulsing. With each further approach of the threat to the emergency services, the frequency of the pulsating red segment can be increased by the control unit.

0022According to a further embodiment, the control unit is set up to assign the information types to the segments as a function of an external control command transmitted by the guidance system, a specific head alignment of the emergency worker and / or a determined position of the emergency worker.

0023If, for example, the control unit receives an external control command to output an assignment or a command from the management system to the emergency worker, the control unit can determine a specific segment for visual output for the output of this command or this assignment. Furthermore, the control unit can determine the assignment of the information types to the segments as a function of a change in the head alignment of the emergency services. If, for example, as shown above, there is a threat in the left field of vision of the emergency services, a corresponding segment will light up red in the left area of ​​the display. If the emergency services then moves their head to the left and the threat does not change its position, the control unit will assign a segment in the central area of ​​the display for the information type threat. Correspondingly, the control unit can also change the assignment of the information types to the segments as a function of a change in the position of the emergency worker, for example a satellite-determined position of the emergency worker.

0024According to a further embodiment, the display device comprises a determination unit for determining the head orientation of the emergency worker, the determination unit having a compass and / or a gyrometer.

0025According to a further embodiment, the display device comprises a determination unit for determining the position of the emergency worker. The determination unit can for example comprise sensors such as gyro sensors, acceleration sensors, pedometers, altimeters or the like.

0026According to a further embodiment, the control unit is set up to assign a first information type and at least one second information type to a specific segment of the plurality of segments.

0027In particular, the control unit can also assign several types of information to a specific segment. For example, the control unit can not only assign a blue force display (for example via the color blue) to a segment, but also assign a motion vector of the blue force (for example via an arrow shown in the segment).

0028According to a further embodiment, the plurality of visually distinguishable segments are arranged in a row.

0029When the operator wears the display device, the row of segments can be arranged particularly close to the eyes, for example a little above the eyes or a little below the eyes, in a peripheral field of vision of the operator. The arrangement of the row of segments in the peripheral field of vision of the emergency personnel has the advantage that, compared to a solution outside the field of vision, a high degree of reaction possibility is provided for the user. The arrangement of the row of segments in the peripheral field of vision of the emergency worker also has the advantage that, compared to an arrangement in an active field of vision of the emergency worker, a minimal restriction is created for the emergency worker.

0030According to a further embodiment, the plurality of visually distinguishable segments are arranged in a matrix.

0031In particular, the number of rows in the matrix is ​​significantly less than the number of columns in the matrix, so that the display with the segments arranged in a matrix can be arranged in a peripheral area of ​​the field of vision of the emergency worker.

0032According to a further embodiment, the row of segments is set up to depict a horizontal visual image of the emergency worker by means of the visual output of the information content of the information types assigned to the segments.

0033The display device is designed as a mask that can be worn in front of the face of the emergency worker. In this case, the visually distinguishable segments are arranged in a peripheral field of vision of the operator when the mask is worn by the operator.

0034The mask can in particular be connected to two headphones for the ears of the emergency worker via straps and via at least one further strap for tensioning the headphones and the mask over the head. The mask can furthermore comprise an embedded microphone, so that the emergency worker can communicate with the guidance system via voice via the microphone and the headphones.

0035In this case, the visually underscriptable segments are arranged when the operator wears the mask in such a way that they are arranged exclusively in the peripheral field of view of the operator and in particular not in the active field of view of the operator.

0036The segments are therefore preferably exclusively in the peripheral field of vision and not in the active field of vision, that is to say the user can recognize them, but the segments and their display only disturb the emergency services to a minimal extent.

0037As an alternative to the design as a mask, the display device is designed as glasses or glasses extension that can be worn by the emergency worker, the visually distinguishable segments being arranged in a peripheral field of vision of the emergency worker when the glasses or the glasses extension are worn.

0038For example, the segments can be arranged above the glasses of the glasses. As a spectacle extension, the segments can be plugged onto glasses, for example, or connected to a frame that can be displaced in the x direction, in the y direction and / or in the z direction.

0039According to a further embodiment, the glasses or the glasses extension are designed in such a way that an alignment of the segments in the x-direction, in the y-direction and in the z-direction can be set.

0040According to a further embodiment, the visually distinguishable segments are arranged in a ring-shaped manner. In particular, the segments form a ring. The segments of the display are preferably flexible.

0041According to a further embodiment, the segments, which are arranged in a ring-shaped distribution, are integrated in a directional system of a weapon or in a telescopic sight.

0042According to a further embodiment, the segments arranged in a ring-shaped manner are arranged in a reconnaissance device or in binoculars.

0043A number of the segments of the plurality of visually distinguishable segments are set up to map an area outside of the operator's visual image, in particular an area behind the operator, by means of the visual output of the information content of the information types assigned to the segments of the number.

0044This makes it possible to assign certain segments, namely the segments of the said number, to areas outside of the emergency services' visual image and thus to make areas visible to the emergency services via these segments that they would not actually be able to see without turning their body and / or head . In particular, these areas are those areas that lie behind the emergency services.

0045According to a further embodiment, each segment of the two outer segments of the plurality of visually distinguishable segments is set up to cover a specific area outside of the operator's visual image, in particular an area behind the operator, by means of the visual output of the information content assigned to the respective segment Map information types.

0046For example, the left outer segment can be assigned to a left area behind the operator, whereas the right outer segment can be assigned to a right area behind the operator. Thus, not only areas outside of his field of vision, in particular behind him, can be made visible to the emergency worker via the outer segments, but he can even perceive different areas outside his field of vision in a differentiated manner. This means, for example, that an enemy within the left area behind the emergency worker is made visible to the emergency worker through the left outer segment, whereas an enemy in the right area behind the emergency worker is made visible to the emergency worker by means of the right outer segment of the display device.

0047According to a further embodiment, the plurality of visually distinguishable segments are arranged on a helmet for the emergency services or integrated in the helmet.

0048According to a further embodiment, the display device comprises a control device. The control device preferably comprises an interface device or data interface which is set up at least for coupling the display. Furthermore, the interface device can also comprise one or more interfaces, for example a USB interface and / or a Bluetooth interface, which are set up for coupling external devices or sensors.

0049In addition, the control device can also include a data processing device, such as a microprocessor, which, for example, integrates the control unit.

0050Furthermore, the control device preferably comprises a communication device for data communication with at least the guidance system. One or more sensors can also be connected via the aforementioned interface device or data interface. Examples of such sensors include a gyroscope, a light sensor, a microphone, an ambient noise suppression and / or a compass.

0051The respective unit, for example the control unit, can be implemented in terms of hardware and / or also in terms of software. In the case of a hardware implementation, the unit can be designed as a device or as part of a device, for example as a computer or as a microprocessor. In a software implementation, the unit can be designed as a computer program product, as a function, as a routine, as part of a program code or as an executable object.

0052A computer program product, such as a computer program means, can for example be provided or delivered as a storage medium such as a memory card, USB stick, CD-ROM, DVD, or also in the form of a downloadable file from a server in a network. This can take place, for example, in a wireless communication network by transmitting a corresponding file with the computer program product or the computer program means.

0053According to a second aspect, an arrangement with a guidance system for guiding a plurality of emergency services and a plurality of display devices is proposed, one of the display devices being assigned to the respective emergency service. The respective display device is designed according to the first aspect or one of the embodiments of the first aspect.
