Description

The present invention relates to an information display system that displays information about a monitoring target in the user's field of view by using a type of display worn on the user's head.

In recent years, a technique for displaying, for example, a virtual reality image or various information has been proposed using a head-mounted display (hereinafter referred to as HMD) that can be worn on the user's head. As an application of this technology, for example, in order to present information on the safety of the robot or the like to a user who works in or near the work area of the robot or the like, the information on the safety is displayed on the HMD worn by the user. It is expected to be done. According to this, the user can acquire information on the safety of the robot or the like without looking into the teaching pendant or the tablet terminal while raising the line of sight, so that the safety can be improved. ..

However, most of the general HMDs have a configuration in which a transparent display unit is arranged in a place overlapping the user's field of view, and various information is displayed on the display unit. In this case, the information displayed on the display unit and the actual scene seen by the user through the display unit overlap. Therefore, for example, when there is a lot of information to be displayed on the display unit, more information can be displayed by expanding the area for displaying the information, but the user's field of view is improved by the various information displayed on the display unit. It will be blocked. On the other hand, by reducing the area for displaying information, it is possible to suppress obstruction of the field of view, but in this case, the characters become small and difficult to see, or necessary information cannot be displayed properly. As described above, depending on the display mode of the information, there is a concern that the safety may be lowered.

JP-A-2015-228201

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information display system capable of safely presenting information in presenting information to a user using a wearable display.

The information display system of the embodiment includes a wearable display that can be worn by the user and can display information within the user's field of view, a monitoring target information acquisition unit that can acquire monitoring target information that is information about the monitoring target, and the like. A display area setting unit that sets a display area for displaying the monitoring target information in the user's field of view, and a monitoring target information in the display area when the amount of the monitoring target information is within the display area. The display control unit includes a display control unit that displays the information to be monitored without scrolling and displays the information to be monitored by scrolling in the display area when the amount of the information to be monitored does not fit in the display area.

According to this, even when the amount of monitoring target information to be displayed in the field of view is large, it is not necessary to expand the display area in the field of view to display all the monitoring target information at the same time. Therefore, even when the amount of information to be monitored is large, it is possible to suppress a situation in which the field of view is filled with the information to be monitored and the field of view is obstructed. That is, by scrolling and displaying the monitoring target information having a large amount of information, it is possible to efficiently display all the monitoring target information while making the display area as small as possible. As a result, it is possible to present safe information without obstructing the user's field of view.

In the information display system of the embodiment, when the amount of information of the monitoring target information falls within the preset maximum area, the display area setting unit can display the monitoring target information without scrolling. The display area is set according to the amount of information, and when the amount of information of the monitored information does not fit within the maximum area, the display area is set to the maximum area.

According to this, when the amount of information of the monitoring target information is small, the display area can be reduced according to the monitoring target information, so that the user's field of view is less likely to be obstructed. Further, according to this, since the display area does not become larger than the maximum area, it is possible to give the user a sense of security that the field of view is not blocked beyond the maximum area. As a result, it becomes possible to present more secure information without obstructing the user's field of view.

In the information display system of the embodiment, the monitored information is classified into at least first rank information having a higher risk and second rank information having a lower risk than the first rank information according to the magnitude of the danger. There is. The display control unit always displays the first rank information, and scrolls and displays the second rank information when the amount of information of the second rank information does not fit within the display area.

According to this, since the high-risk first rank information is always displayed in the field of view, the user can always pay attention to the high-risk first rank information. Further, since the second rank information having a low degree of risk is scrolled and displayed, the display area can be reduced even when the amount of information to be monitored is large. Therefore, the display area can be reduced as a whole while making it easier to check the information having a higher degree of risk, and as a result, the user's field of view is not obstructed and more secure information can be presented.

In the information display system of the embodiment, the display control unit repeatedly displays the second rank information by scrolling at a fixed cycle, and accelerates the scroll cycle as the amount of information of the second rank information increases. .. According to this, even when the amount of information of the second rank information becomes large, the period of one cycle of scrolling can be shortened as much as possible. Therefore, when the user wants to see a specific information among the scrolled second rank information, he / she can see the desired information as soon as possible.

Further, the user can estimate the amount of information of the second rank information by the speed of scrolling the second rank information that is repeatedly performed at a fixed cycle, that is, the length of time until the same information is displayed again. .. Therefore, the user can visually and intuitively recognize the amount of information of the second rank information, which is convenient.

In the information display system of the embodiment, the display control unit displays at least the latest monitoring target information among the monitoring target information newly acquired by the monitoring target information acquisition unit for a predetermined period without scrolling. According to this, the user can secure a period for paying attention to the newly added latest monitoring target information separately from other monitoring target information. Therefore, the user can pay more attention to the newly added latest monitored information, and more secure information can be presented.

In here continuous, in the above arrangement, since the number of monitoring target information that can be displayed simultaneously on the display area is limited, the target-of-monitoring information acquisition unit, the monitoring target information of a plurality of new in a short period of time If it is acquired in this way, all newly acquired monitoring target information may not be displayed in the display area.

Therefore, the information display system according to the embodiment, the display control unit has acquired the following monitored information while displaying the monitored information to which the said target-of-monitoring information acquisition unit has acquired without scrolling In this case, the next monitoring target information is displayed as the latest monitoring target information without scrolling, and the previous monitoring target information is scrolled to interrupt and scroll to other displayed monitoring target information. indicate.

According to this, even when the monitoring target information acquisition unit continuously acquires a plurality of new monitoring target information in a short period of time, at least the latest monitoring target information is displayed without scrolling. It can be displayed in the area. As a result, the user can pay attention to at least the latest monitoring target information separately from other monitoring target information. Then, the monitoring target information acquired before the latest monitoring target information is acquired is also displayed by interrupting the scroll display of other monitoring target information. Therefore, the user can confirm the previous monitoring target information, that is, the monitoring target information which was the latest monitoring target information until immediately before, by looking at the scrolling display. As described above, according to this configuration, the user can confirm these new monitoring target information even when a plurality of new monitoring target information are continuously generated within the period. As a result, more secure information can be presented.

In the information display system of the embodiment, when the display control unit interrupts and displays the other monitoring target information that has already been scrolled and displayed, the monitoring target information of the destination is displayed. Is displayed in a mode different from the display mode of the other monitoring target information. According to this, the user can easily distinguish between the monitoring target information that interrupts the scroll display of other monitoring target information and the other monitoring target information that has been scrolled and displayed from before. Therefore, the user can easily grasp which of the monitored information displayed by scrolling is the newly interrupted monitored information, and as a result, more secure information can be presented. ..

In the information display system of the embodiment, the display control unit scrolls the other monitoring target information in a direction away from the display position of the latest monitoring target information, and the other monitoring displayed in the display area. The monitoring target information of the destination is interrupted at the end of the target information, and the monitoring target information of the destination is scrolled and displayed together with the other monitoring target information.

According to this, when the previous monitoring target information is interrupted and displayed by the other monitoring target information that has already been scrolled and displayed, the previous monitoring target information is scrolled from the non-scrolling display. It is possible to switch smoothly with a continuous appearance. Therefore, the user can easily recognize that the monitoring target information that is interrupted by the other scrolled monitoring target information is the latest monitoring target information that was displayed without scrolling until immediately before. This makes it easier for the user to pay attention to the monitored information displayed by scrolling, that is, the monitored information displayed without scrolling without interruption, and as a result, more secure information presentation. Becomes possible.

In contrast, in the information display system according to the embodiment, the display control unit is displayed with scrolling the other monitoring target information direction toward the display position of the latest monitoring target information in the display region The destination monitoring target information is interrupted at the end of the other monitoring target information, and the destination monitoring target information is scrolled and displayed together with the other monitoring target information.

According to this, when the previous monitoring target information is interrupted and displayed by the other monitoring target information that has already been scrolled and displayed, the previous monitoring target information is scrolled from the non-scrolling display. It is possible to switch to with a discontinuous appearance. Therefore, the user can easily recognize that the latest monitoring target information displayed without scrolling has been switched from the previous monitoring target information to the current latest monitoring target information. This makes it easier for the user to pay more attention to the latest monitored information, and as a result, enables safer information presentation.

In the information display system of the embodiment, the display control unit displays the inside of the display area opaquely. According to this, it is possible to prevent the monitored target information displayed in the display area from being mixed into the actual scene behind the display area, and as a result, the monitored target information can be made easier to see.

In the following description, when these two robots 11 are distinguished, they are referred to as a first robot 111 and a second robot 112. Further, the robot controller 12 corresponding to the first robot 1 11 and the second robot 112, referred to as a first robot controller 121 and the second robot controller 122, respectively.

The robot 11 is composed of, for example, a 6-axis vertical articulated robot. Although detailed description of the general configuration will be omitted, the robot 11 has a 6-axis arm driven by a servomotor, and grips a work housed in, for example, a pallet at the tip of the 6-axis arm. It is equipped with a hand for doing so. The robot 11 is connected to the robot controller 12 via a connection cable (not shown). The servomotor of each axis is controlled by the robot controller 12.

The robot controller 12 includes a control circuit (not shown), a servo control unit, a power supply device, and the like. The control circuit is mainly composed of a microcomputer. The robot controller 12 controls each axis servomotor of the robot 11 via the servo control unit according to an operation program stored in advance, teaching data set by a teaching pendant (not shown), various parameters, and the like. As a result, the robot controller 12 causes each robot 11 to automatically perform work assembly work and the like.

Each robot controller 12 is communicably connected to the safety device 13. The safety device 13 is configured to be able to acquire various information capable of specifying the operating state of each robot 11 and the control state by each robot controller 12 from the robot controller 12 side. Therefore, the safety device 13 can acquire operation information indicating the operation state of the robot 11 and control information indicating the control state of the controller 12 in real time, such as the rotation angle of the arm of the robot 11 and the energization state of the motor.

Further, the safety device 13 can generate 3D model image data in which the current form, that is, the posture of the robot 11 is three-dimensionally modeled based on the information of each robot 11 acquired from each robot controller 12. The safety device 13 also stores the coordinates of each robot 11 in the area where each robot 11 is installed, for example, the coordinates of each robot 11 in the two-dimensional coordinate system with the reference position in the factory as the origin, that is, the installation position of the robot 11.

The HMD 20 is configured to be worn on the user's head, and various information can be displayed in the user's field of view. The HMD 20 may be either a binocular type that covers both eyes or a monocular type that covers only one eye, but this embodiment is more suitable for a binocular type that easily deprives the user of the field of vision. Further, the shape of the HMD 20 is assumed to be a spectacles type worn like spectacles or a hat type worn like a hat, but any of them may be a shape. The HMD 20 of the present embodiment assumes a spectacle type.

As shown in FIG. 2, the HMD 20 has a display unit 21 and a camera 22. The display unit 21 is provided at a position that overlaps with the user's field of view when the user is wearing the HMD 20. In the case of the present embodiment, the display unit 21 is a portion corresponding to the lens portion of the spectacles, and is composed of a so-called transmissive display capable of displaying information such as an image. Therefore, the image displayed on the HMD 20 is displayed so as to overlap the user's field of view. In other words, the user sees the real landscape as seen by his own eyes and the virtual image displayed by the HMD 20 together.

The camera 22 is composed of a small CCD camera or a CMOS camera, and is integrally attached to the HMD 20. The camera 22 is provided on one side of the frame of the HMD 20 so as to match the orientation of the user's face. As shown in FIG. 1, the camera 22 captures an image in the direction in which the front surface of the head of the user 90 is facing while the user 90 is wearing the HMD 20 on the head. Therefore, the image captured by the camera 22 has almost the same angle of view as the field of view of the user 90. In other words, the camera 22 captures a landscape that is substantially the same as the landscape that the user 90 is viewing.

The display unit 21 is not limited to the transmissive display, and may be configured by a non-transparent display. In this case, the HMD 20 virtually presents the landscape captured by the camera 22 to the user by displaying the image captured by the camera 22 on the display unit 21 in real time, that is, the user's field of view is reproduced on the display unit 21. Just do it. Further, the HMD 20 is not limited to the one having the display unit 21, and may be a retinal projection type that directly projects a virtual image onto the user's retina.

The HMD 20 is connected to the display control device 30 wirelessly or by wire. The display control device 30 may be integrally configured with the HMD 20. As shown in FIG. 2, the display control device 30 has a built-in control unit 31 composed of a microcomputer or the like, and transmits image data to be displayed on the display unit 21 of the HMD 20 or is photographed by the camera 22. Receive image data. Further, the display control device 30 can perform wired or wireless communication with the safety device 13.

As shown in FIG. 2, in addition to the control unit 31, the display control device 30 includes a monitoring target information acquisition unit 32, a visibility information acquisition unit 33, a monitoring target identification unit 34, a display area setting unit 35, and a display control unit 36. Have. The control unit 31 is mainly composed of a microcomputer having a storage area 312 such as a CPU 311, a ROM, a RAM, and a rewritable flash memory, and controls the entire HDM 20.

The storage area 312 stores the information display program. By executing the information display program in the CPU 31, the control unit 31 software-uses the monitoring target information acquisition unit 32, the visibility information acquisition unit 33, the monitoring target identification unit 34, the display area setting unit 35, the display control unit 36, and the like. Realize. The monitoring target information acquisition unit 32, the visibility information acquisition unit 33, the monitoring target identification unit 34, the display area setting unit 35, and the display control unit 36 are realized in hardware as, for example, an integrated circuit integrated with the control unit 31. You may.

The monitoring target information acquisition unit 32 can acquire monitoring target information in real time from the safety device 13 as information about each robot 11 to be monitored. The monitoring target information is composed of information and the like that change at any time depending on the operation of each robot 11. For example, the monitoring target information includes operation information indicating the operation state of each robot 11 including the above-mentioned 3D model image data, and control information indicating the control state of the controller 12. Further, the monitoring target information includes, for example, warning caution information for presenting a warning or caution regarding the robot 11 to the user.

3 to 10 conceptually show an example of the monitoring target information 40 acquired by the monitoring target information acquisition unit 32 and stored in the storage area 312. In the case of the present embodiment, for example, as shown in FIG. 3, the monitoring target information 40 includes at least two of the first rank information 41 and the second rank information 42 according to the degree of danger given to the user, that is, the magnitude of the danger. It is classified into two ranks. The first rank information 41 indicates that the risk given to the user is high. The second rank information 42 indicates that the risk given to the user is smaller than that of the first rank information 41.

Further, the monitoring target information acquisition unit 32 determines the information newly acquired from the safety device 13 after acquiring the information regardless of whether the classification is the first rank information 41 or the second rank information 42. The period is classified into new information 43. In the present embodiment, the first rank information 41 is represented by adding the characters "DANGER". The second rank information 42 is represented by adding the characters “WARNING”. The new information 43 is represented by adding the characters "NEW". These characters "DANGER", "WARNING", and "NEW" are identifiers for identifying the type of each information.

The first rank information 41, the second rank information 42, and the new information 43 are composed of individual information. The monitoring target information acquisition unit 32 stores each individual information of the first rank information 41, the second rank information 42, and the new information 43 in the storage area 312 in the order of acquisition. For example, in the present embodiment, each individual information of the first rank information 41 is designated by reference numerals D1, D2 ... As shown in FIGS. 3 and 10. In this case, the information with D1 means that it was acquired before the information with D2. Further, as shown in FIGS. 3 and 4, each individual information of the second rank information 42 is designated by W1, W2, .... In this case, the information with W1 means that the information with W2 was acquired before the information with W2.

In the present embodiment, each individual information stored in the storage area 312 becomes the information displayed in the display area 211 of the HMD 20. For example, in the example of FIG. 3, the storage area 312 includes the individual information of the first rank information 41 with D1 as the information displayed on the HMD 20, and the individual information of the second rank information 42 with W1 and W2. However, the individual information of the new information 43 is not stored.

The field of view information acquisition unit 33 shown in FIG. 2 can perform a process of acquiring the field of view information for specifying the field of view of the user 90 wearing the HMD 20. The field of view of the user 90 means a landscape seen by the user 90 when the user 90 is wearing the HMD 20. In the case of the present embodiment, the field of view of the user 90 means the scenery seen by the user 90 through the display unit 21 which is the lens portion of the spectacles. The visibility information acquisition unit 33 acquires the visibility information of the user 90 from, for example, an image captured by the camera 22. In the present embodiment, for example, as shown in FIG. 3, the image pickup range 221 of the camera 22 and the area of the display unit 21 are simulated as the field of view 91 of the user 90.

The monitoring target identification unit 34 shown in FIG. 2 can perform a process of identifying the robot 11 that is a monitoring target existing in the field of view 91 of the user 90 based on the field of view information acquired by the field of view information acquisition unit 33. That is, the monitoring target identification unit 34 can identify, that is, identify whether the monitoring target, that is, the robot 11, which exists in the user's field of view 91, is the robot 111 or 112. The monitoring target identification unit 34 can identify each robot 11 as follows, for example. That is, for example, each robot 11 is attached with a marker for identifying an individual. Then, the monitoring target identification unit 34 can identify each robot 11 by recognizing the marker attached to the robot 11 based on the image captured by the camera 22.

As another method, the monitoring target identification unit 34 can identify each robot 11 as follows, for example. That is, the monitoring target identification unit 34 acquires the current 3D model image data of each robot 11 from the safety device 13. Then, the monitoring target identification unit 34 can identify each robot 11 by collating the 3D model image data of each robot 11 with the form of the robot 11 captured by the camera 22. In this case, the monitoring target information acquisition unit 32 selectively acquires the monitoring target information 40 for the robot 11 that has entered the user's field of view 91 by the processing of the field of view information acquisition unit 33 and the monitoring target identification unit 34. You may.

As shown in FIG. 3, for example, the display area setting unit 35 can perform a process of setting a display area 211 for displaying the monitoring target information 40 in the user's field of view 91. The display area setting unit 35 sets the display area 211 according to the amount of information of the monitoring target information 40 acquired from the monitoring target information acquisition unit 32, that is, the amount of information of the current monitoring target information 40 stored in the storage area 312. Is set to a size suitable for the amount of information.

That is, first, as shown in FIG. 3, the display area setting unit 35 virtually sets the maximum area 212 in advance as the maximum range in which the display area 211 can be expanded, that is, the maximum size of the display area 211. The maximum area 212 may be arbitrarily set by the user, or may be set in advance by the manufacturer or the like. Further, the position of the maximum region 212 in the field of view 91 may be fixed or may be changed according to the position of the monitoring target 11 in the field of view 91.

Next, the display area setting unit 35 sets the display area according to the amount of information of the monitoring target information 40 acquired from the monitoring target information acquisition unit 32, that is, the amount of information of the current monitoring target information 40 stored in the storage area 312. Set the size of 211. In this case, if the amount of information of the current monitoring target information 40 fits within the maximum area 212, the display area setting unit 35 adjusts to the amount of information of the current monitoring target information 40 as shown in FIG. The display area 211 is set to a size such that all the monitoring target information 40 is displayed in the display area 211. Therefore, in this case, the size of the display area 211 is smaller than or equal to the size of the maximum area 212. If the amount of information of the current monitoring target information 40 does not fit within the maximum area 212, the display area setting unit 35 sets the size of the display area 211 to the size of the maximum area 212 as shown in FIG. 4 and the like. ..

In this embodiment, whether or not the amount of information of the monitoring target information 40 fits within the maximum area 212 is when all the monitoring target information 40 stored in the storage area 312 are displayed at the same time in a predetermined font size. In addition, it means whether or not it fits in the maximum area 212, that is, whether or not there is a portion protruding from the maximum area 212.

As shown in FIGS. 3 to 10, the display control unit 36 displays character information, numbers, figures, symbol information, etc. constituting the monitoring target information 40 in the display area 211 set by the display area setting unit 35. do. In the case of the present embodiment, the display control unit 36 displays the inside of the display area 211 opaquely in a color opposite to the monitoring target information 40 displayed in the display area 211, for example, so that the actual view behind the display area 211 is displayed. Is obscuring. As a result, it is possible to prevent the monitoring target information 40 displayed in the display area 211 from being mixed into the actual scene behind the display area 211, so that the monitoring target information 40 displayed in the display area 211 becomes easy to see. Since the display area 211 is an area for displaying the monitoring target information 40, the display control unit 36 does not necessarily have to display the frame indicating the display area 211 and the color in the display area 211.

Here, the solid line borders 44, 45, and 46 shown in FIGS. 3 to 10 are displayed in the display area 211 of the HMD 20 by the display control unit 36 among the monitoring target information 40 stored in the storage area 312. Information is shown. In this case, of the monitoring target information 40 stored in the storage area 312, the information surrounded by the frame lines 44, 45, 46 is displayed in the display area 211.

As shown in FIG. 3, when the amount of information of the monitoring target information 40 fits in the display area 211, the display control unit 36 simultaneously displays all the information of the monitoring target information 40 in the display area 211 without scrolling. .. On the other hand, as shown in FIG. 4, when the amount of information of the monitoring target information 40 does not fit in the display area 211, that is, when a part of the monitoring target information 40 overflows from the display area 211, the display control unit 36 sets the display control unit 36. As shown in FIGS. 4 to 6 and the like, all or part of the monitoring target information 40 stored in the storage area 312 is scrolled and displayed in the display area 211 at regular intervals.

Here, in the present embodiment, the terms "scroll display" and "scroll display" are synonymous. The "scroll display" and "scroll display" mean a display mode in which the monitoring target information 40 that does not fit in the display area 211 is displayed by sliding it horizontally or vertically. Further, in the present embodiment, the terms "scrolling cycle" and "scrolling speed" are synonymous.

In the case of the present embodiment, the display control unit 36 scrolls and displays all or part of the monitoring target information 40 so that all or part of the monitoring target information 40 flows upward in the field of view 91. That is, in the examples shown in FIGS. 4 to 6, the number of individual information of the second rank information 42 displayed in the display area 211 is constant at 5, and the 5 individual information is sequentially switched. Is displayed. Then, when the individual information of all the second rank information 42 is scrolled and displayed, the process returns to the beginning and is repeated. That is, in the present embodiment, the display control unit 36 repeatedly scrolls and displays the individual information of the second rank information 42 at regular intervals.

In this case, the speed of the scroll display, that is, the speed of the monitored information 40 flowing upward can be made constant regardless of the amount of information of the monitored information 40. In the present embodiment, the non-scrolling display mode, that is, the display mode in which the scroll display is fixed at a fixed position is referred to as a non-scroll display.

The display control unit 36 reduces the amount of information of the monitoring target information 40 acquired by the monitoring target information acquisition unit 32, and keeps the monitoring target information 40 until the display of the monitoring target information 40 fits within the display area 211. Continue scrolling. That is, when the amount of information of the monitoring target information 40 acquired by the monitoring target information acquisition unit 32 decreases and the display of the monitoring target information 40 fits within the display area 211, the display control unit 36 causes the monitoring target information 40. Switch from scrolling display to non-scrolling display.

In the case of the present embodiment, the display control unit 36 always displays the first rank information 41 and the new information 43 of the monitored information 40 in a non-scrolling display as shown in FIGS. 4 to 10. Further, the display control unit 36 displays the second rank information 42 of the monitored information 40 while switching between scroll display and non-scroll display as needed, that is, according to the amount of information of the monitored information 40.

That is, if the monitoring target information 40 includes the first rank information 41, the display control unit 36 does not scroll the first rank information 41 into the display area 211 regardless of the amount of information of the monitoring target information 40. Always display on. Further, when the monitoring target information 40 includes the second rank information 42 and the monitoring target information 40 fits within the maximum area 212, the display control unit 36 performs the second rank information 42 together with the first rank information 41. Is always displayed in the display area 211 without scrolling. On the other hand, when the monitoring target information 40 includes the second rank information 42, but the monitoring target information 40 does not fit within the maximum area 212, the display control unit 36 scrolls and displays the second rank information 42. It is displayed in the area 211.

Further, the monitoring target information acquisition unit 32 acquires the monitoring target information 40 from the safety device 13 at any time regardless of the control content of the display control unit 36. In this case, as shown in comparison with FIGS. 6 and 7, when the user's field of view 91 changes or the state of the robot 11 changes, the monitored information acquisition unit 32 is newly stored in the storage area 312. Get information 43. Then, as shown in FIG. 7, the display control unit 36 displays the newly acquired new information 43 in the display area 211 for a predetermined period without scrolling, that is, in a non-scrolling display. In this case, when a plurality of newly acquired new information 43 exists, the display control unit 36 displays at least the latest new information 43, that is, the last acquired new information 43, in the display area 211 in a non-scrolling display. indicate.

Further, in this case, the predetermined period may be arbitrarily set by the user in advance, or may be set in advance by the manufacturer or the like, for example, in a time of about 10 seconds to 1 minute. Further, the predetermined period can be set to be variable according to the scroll display cycle of the second rank information 42. For example, when the predetermined period is set to one cycle of the scroll display of the second rank information 42, the display control unit 36 determines the period during which the scroll display of the second rank information 42 makes one round, that is, each individual information of the second rank information 42. The new information 43 is always displayed in a non-scrolling display during the period from one round to the same position again.

Then, when the display control unit 36 displays the new information 43 in a non-scrolling display for a predetermined period, if the new information 43 belongs to the second rank information 42, as shown by the white arrow in FIG. The new information 43 is added to the second rank information 42 as the tail end of the second rank information 42, in this case, the individual information W9. Then, as shown in FIG. 9, the display control unit 36 scrolls and displays the second rank information 42 including the added individual information W9. That is, when the new information 43 belongs to the second rank information 42, the display control unit 36 displays the new information 43 in a non-scrolling display for a predetermined period, and then scrolls the new information 43 to the second rank information 42. Incorporate into the display.

On the other hand, if the new information 43 belongs to the first rank information 4 1, as shown by a hollow arrow in FIG. 10, the new information 43 end of the first rank information 41, in this case, as the individual information D2 It is added to the first rank information 41. Then, as shown in FIG. 10, the display control unit 36 displays the first rank information 41 in a non-scrolling display, including the added individual information D2.

Here, the scroll display of the second rank information 42 can be set to a constant speed regardless of the amount of information of the second rank information 42. In this case, if the amount of information of the second rank information 42 is small, the period during which the second rank information 42 makes one round due to the scroll display is short, so that the time during which the new information 43 is non-scrolled is also short. However, since the period during which the second rank information 42 makes one round is short, the user compares the new information 43 incorporated in the second rank information 42 even after the new information 43 is added to the second rank information 42. Can be seen frequently.

Further, when the scroll display of the second rank information 42 is set to a constant speed, if the amount of information of the second rank information 42 is large, the period in which the second rank information 42 makes one round due to the scroll display is long. Therefore, after the new information 43 is added to the second rank information 42, the user is less likely to see the new information 43 incorporated in the second rank information 42. However, in this case, the new information 43 is displayed for a long time in a non-scrolling manner before being added to the second rank information 42. Therefore, according to this configuration, it is possible to secure a sufficient time for the user to confirm the new information 43 regardless of the amount of information of the second rank information 42.

Further, the display control unit 36 repeatedly displays the second rank information 42 by scrolling at a fixed cycle. In this case, for example, the larger the amount of information of the monitoring target information 40 to be scrolled, the faster the scrolling speed is. It is also possible to shorten the period of one cycle. In other words, the display control unit 36 may slow down the scrolling speed and lengthen the period of one cycle as the amount of information of the monitoring target information 40 to be scrolled and displayed decreases. According to this, even when the amount of information of the monitoring target information 40 becomes large, the period of one cycle of scrolling can be shortened as much as possible. Therefore, when the user wants to see a specific information among the scrolled second rank information 42, the user can see the desired information as soon as possible.

Further, the user determines the information of the second rank information 42 depending on the speed of scrolling of the second rank information 42 that is repeatedly performed, that is, the length of time until the same individual information is displayed again for the second rank information 42. The amount can be estimated. Therefore, the user can visually and intuitively recognize the magnitude of the amount of information of the second rank information 42, that is, the large amount of information regarding danger, which is convenient.

Next, the control flow performed by the control unit 31 of the display control device 30 will be described with reference to FIG. When the control unit 31 executes the information display program, the control unit 31 executes the control flow shown in FIG. First, in step S11, the control unit 31 determines whether or not the monitoring target information 40 has been acquired by the monitoring target information acquisition unit 32. When the monitoring target information 40 is not acquired (NO in step S11), the control unit 31 determines that the monitoring target information 40 to be displayed does not exist in the field of view 91, returns the process to step S11, and repeats the process.

On the other hand, when the monitoring target information 40 is acquired (YES in step S11), the control unit 31 determines that the monitoring target information 40 to be displayed exists in the field of view 91, and shifts the process to step S12. In step S12, the control unit 31 determines whether or not the amount of acquired monitoring target information 40 is within the maximum area 212. When the acquired information amount of the monitoring target information 40 fits within the maximum area 212 (YES in step S12), the control unit 31 sets the size of the display area 211 to the size of the maximum area 212 by the processing of the display area setting unit 35. Set as follows.

Then, the control unit 31 shifts the processing to step S14, and by the processing of the display control unit 36, the first rank information 41, the second rank information 42, and the new information 43 of the monitored information 40 are all, that is, all. The monitoring target information 40 is displayed in the display area 211 in a non-scrolling display. After that, the process is shifted to step S11, and steps S11 and subsequent steps are repeated.

On the other hand, when the acquired information amount of the monitoring target information 40 does not fit within the maximum area 212 (NO in step S12), the control unit 31 maximizes the size of the display area 211 by the processing of the display area setting unit 35. Set to the same size as the size of the area 212. Then, the control unit 31 shifts the process to step S15, and by the process of the display control unit 36, the first rank information 41 and the new information 43 of the monitored information 40 are displayed in the display area 211 in a non-scrolling display. At the same time, the second rank information 42 is scrolled and displayed in the display area 211. After that, the process is shifted to step S11, and steps S11 and subsequent steps are repeated.

According to the embodiment described above, in the information display system 10, when the amount of information of the monitoring target information 40 fits within the display area 211, the display control unit 36 scrolls the monitoring target information 40 in the display area 211. Display without. On the other hand, when the amount of information of the monitoring target information 40 does not fit in the display area 211, the display control unit 36 scrolls and displays the second rank information 42 of the monitoring target information 40 in the display area 211.

According to this, even when the amount of information of the monitoring target information 40 to be displayed in the field of view 91 is large, it is not necessary to expand the display area 211 in the field of view 91 to display all the monitoring target information 40 at the same time. .. Therefore, even when the amount of information of the monitoring target information 40 is large, it is possible to suppress a situation in which the field of view 91 is filled with the monitoring target information 40 and the field of view 91 is obstructed. That is, by scrolling and displaying the monitoring target information 40 having a large amount of information, it is possible to efficiently display all the monitoring target information 40 while making the display area 211 as small as possible. As a result, it is possible to present information safely without obstructing the field of view 91 of the user 90.

Further, in the present embodiment, when the amount of information of the monitoring target information 40 falls within the preset maximum area 212, the display area setting unit 35 can display the monitoring target information 40 without scrolling. The display area 211 is set according to the amount of information of 40. Then, when the amount of information of the monitoring target information 40 does not fit within the maximum area 212, the display area setting unit 35 sets the display area 211 to the same size as the maximum area 212.

According to this, when the amount of information of the monitoring target information 40 is small, the display area 211 can be reduced in accordance with the monitoring target information 40, so that the field of view 91 of the user 90 is less likely to be obstructed. Further, according to this, since the display area 211 is not larger than the maximum area 212, it is possible to give the user 90 a sense of security that the field of view 91 is not obstructed beyond the maximum area 212. As a result, it is possible to present information more safely without obstructing the field of view 91 of the user 90.

Further, in the present embodiment, the monitoring target information 40 is classified into first rank information 41 having at least a high risk level and second rank information 42 having a lower risk level than the first rank information 41 according to the magnitude of the danger. Has been done. The display control unit 36 always displays the first rank information 41 having a high degree of risk among the monitored information 40. Then, when the amount of information of the second rank information 42 does not fit within the display area 211, the display control unit 36 scrolls and displays the second rank information 42 having a relatively low risk among the monitored information 40. ..

According to this, since the high-risk first rank information 41 is always displayed in the field of view 91, the user 90 can always pay attention to the high-risk first rank information 41. Further, since the second rank information 42 having a low degree of risk is scrolled and displayed, the display area 211 can be reduced even when the amount of information of the monitored information 40 is large. Therefore, the display area 211 can be reduced as a whole while making it easier to confirm information having a higher degree of risk, and as a result, the field of view 91 of the user 90 is not obstructed, and more secure information can be presented.

Here, the display control unit 36 may increase the scroll speed as the amount of information of the second rank information 42 increases. According to this, even when the amount of information of the second rank information 42 becomes large, the period of one cycle of scrolling can be shortened as much as possible. Therefore, when the user 90 wants to see a specific individual information in the scrolled second rank information 42, the user 90 can see the desired individual information as soon as possible. Further, the user 90 can visually and intuitively recognize the amount of information of the second rank information 42 depending on the scrolling speed, which is convenient.

Further, in the present embodiment, the display control unit 36 displays the monitoring target information 40 newly acquired by the monitoring target information acquisition unit 32, that is, the new information 43 for a predetermined period without scrolling. According to this, the user 90 can secure a period for paying attention to the newly added monitoring target information 40, that is, the new information 43, separately from the other monitoring target information 40. Therefore, the user 90 can pay more attention to the new information 43, and more secure information can be presented.

Further, in the present embodiment, the display control unit 36 displays the inside of the display area 211 opaquely. According to this, it is possible to prevent the monitored object information 40 displayed in the display area 211 from being mixed in with the actual scene behind the display area 211, and as a result, the monitored object information 40 can be made easier to see.

(Second Embodiment)
Next, the second embodiment will be described with reference to FIGS. 12 to 16.
In the present embodiment, since the amount of information of the monitoring target information 40 is not contained in the display area 211 set in the maximum area 212, the display control unit 36 is the monitoring target information 40 stored in the storage area 312. It is assumed that each second rank information 42 is scrolled and displayed at regular intervals.

In this case, each second rank information 42 is scrolled and displayed so as to flow downward in the field of view 91 as shown by the arrow A in FIG. Then, in the display area 211, the latest new information 43 with the characters "NEW" is displayed above the second rank information 42 with the characters "WARNING". Therefore, each second rank information 42 is scrolled and displayed in a direction away from the display position of the latest new information 43.

In the description of the present embodiment, the new information 43 is numbered N1, N2, ... In the order of acquisition. In this case, the new information 43 with N1 means that it was acquired before the new information 43 with N2. Then, the one having the highest number among the new information 43 is the latest new information 43. In the following description, when the acquisition order of each new information 43 is shown separately, the new information 43 (N1) and the new information 43 (N2) are numbered in parentheses.

Further, in the present embodiment, at least the latest new information 43 among the newly acquired new information 43 is displayed for a predetermined period without scrolling. This predetermined period is the same as the predetermined period of the first embodiment, and may be arbitrarily set by the user, for example, or may be set in advance by a manufacturer or the like, for example, at a time of about 10 seconds to 1 minute. good. Further, the predetermined period may be set to be variable according to the scroll display cycle of the second rank information 42.

Further, the present embodiment assumes a case where the monitored information acquisition unit 32 continuously acquires a plurality of new information 43. In the present embodiment, the fact that a plurality of new information 43s are continuously acquired means that the period from the acquisition of the previous new information 43 to the acquisition of the next new information 43 does not scroll the latest new information 43. It means that the above-mentioned predetermined period for displaying has not passed.

Here, in the first embodiment, since the maximum size of the display area 211, that is, the maximum area 212 is preset, the number of monitoring target information 41, 42, 43 that can be simultaneously displayed in the display area 211 is limited. There is. Therefore, if the monitoring target information acquisition unit 32 continuously acquires a plurality of new information 43 within a short period of time, a part of each newly acquired new information 43 may not be displayed in the display area 211. be.

Therefore, in the present embodiment, the display control unit 36 is displaying the monitoring target information 43 acquired by the monitoring target information acquisition unit 32 without scrolling, that is, the next monitoring is performed before the predetermined period elapses. When the target information 43 is acquired, the next monitoring target information 43 is displayed as the latest monitoring target information without scrolling, and the previous monitoring target information 43 is already scrolled and displayed. To interrupt and scroll to display.

That is, when the monitoring target information acquisition unit 32 continuously acquires a plurality of new information 43, the display control unit 36 displays the latest new information 43 at the present time without scrolling into the display area 211, and displays the latest information 43. The new information 43 other than the new information 43 of the above is scrolled together with the second rank information 42 and displayed in the display area 211. In the present embodiment, as shown in FIG. 12 and the like, each second rank information 42 is displayed by scroll display below the characters of "WARNING" indicating that the second rank information 42 is the second rank information 42. Further, the latest new information 43 is displayed in a non-scrolling display below the characters "NEW" indicating that the latest new information 43 is the latest new information 43.

Specifically, as shown in FIG. 12, for example, when the monitoring target information acquisition unit 32 first acquires the new information 43 (N1), the new information 43 (N1) is stored in the storage area 312. At this time, since new information other than the new information 43 (N1) is not stored in the storage area 312, the new information 43 (N1) becomes the latest new information at the present time. Then, as shown from FIGS. 12 to 13, the display control unit 36 displays the latest new information 43 (N1) in the display area 211 in a non-scroll display, and scrolls each second rank information 42. Is displayed sequentially in the display area 211.

Next, as shown in FIG. 14, when the monitored information acquisition unit 32 acquires the next new information 43 (N2), the new information 43 (N2) is stored in the storage area 312 and is the latest at the present time. It becomes new information of. Then, the display control unit 36 replaces the previous new information 43 (N1) with the latest new information 43 (N2), and displays the latest new information 43 (N2) in a non-scrolling display. That is, in this case, the latest new information 43 (N2) is displayed by non-scrolling display below the character "NEW" indicating that the latest new information 43 (N2) is the latest new information 43. Then, as shown from FIGS. 14 to 16, the display control unit 36 interrupts the above-mentioned new information 43 (N1) into the second rank information 42 that has already been scrolled, and together with the second rank information 42. Scroll to display.

In this case, the new information 43 (N1) is within the second rank information 42, that is, the frame line 45 of FIG. 13, which is actually displayed in the display area 211 at the present time, as shown by the white arrow in FIG. It is incorporated at the end of the second rank information 42 (W2, W3, W4) in. By the way, in this case, the new information 43 (N1) is acquired after the last acquired second rank information 42 (W6) among the second rank information 42 stored in the storage area 312. , It can also be regarded as the second rank information 42 (W7). As a result, as shown in FIG. 14, the display control unit 36 is located in the display area 211 closest to the display position of the latest new information 43 (N2) in the area where each second rank information 42 is displayed. Is interrupted by the new information 43 (N1).

For example, in the example shown from FIG. 13 to FIG. 14, the display control unit 36 is placed at the display position of the second rank information 42 (W4) displayed directly under “WARNING” indicating the second rank information 42 in FIG. The previous new information 43 (N1) is interrupted. Then, as shown from FIGS. 14 to 16, the display control unit 36 scrolls the previous new information 43 (N1) together with the second rank information 42 in the direction away from the latest new information 43 (N2) in this case downward. Let me display it.

When the display control unit 36 interrupts and displays the previous new information 43 (N1) with other monitoring target information that has already been scrolled and displayed, that is, the second rank information 42, the previous new information 43 (N1) N1) is displayed in a mode different from the display mode of the other second rank information 42 that has already been scrolled. In the present embodiment, displaying in a different manner means, for example, that the character size, font type, color, or surrounding color of the new information 43 (N1) is displayed by scrolling to another second rank. It means that the information 42 is different from the information 42 or a unique symbol is attached. In this case, the new information 43 (N1) and the other second rank information 42 are displayed to the extent that the user can at first glance distinguish the new information 43 (N1) from the other second rank information 42. It suffices if the aspects are different. In the present embodiment, for example, as shown in FIGS. 14 to 16, the display control unit 36 displays the new information 43 (N1) to which the interrupt is performed with a unique color around it.

Then, the display control unit 36 displays the new information 43 (N1) in a predetermined period or a predetermined cycle in a manner different from that of the other second rank information 42, and then displays the new information 43 (N1) and other information 43 (N1). The display mode with the second rank information 42 is displayed as the same. After that, the display control unit 36 includes the above-mentioned new information 43 (N1) in the second rank information 42 and repeats the scroll display as in the first embodiment.

According to this configuration, even when the monitored information acquisition unit 32 continuously acquires a plurality of new new information 43 within a short period of time, at least the latest new information 43 is not scrolled. It can be displayed in the display area 211. As a result, the user can pay attention to at least the latest new information 43 separately from the other monitored information 41 and 42.

Then, the new information 43 (N1 in the present embodiment) acquired before the latest new information 43 (N2 in the present embodiment) is also the scroll of other monitoring target information in this case, the second rank information 42. It is displayed by interrupting the display. Therefore, the user can confirm the previously monitored information, that is, the new information 43 (N1 in the present embodiment), which is the latest new information until just before, by looking at the scrolling display. As described above, according to the present embodiment, even when a plurality of new information 43s are continuously generated in a short period of time, the user can confirm the new information 43s (N1, N2) at the same time. As a result, more secure information can be presented.

Further, the display control unit 36 scrolls the second rank information 42 in the direction away from the display position of the latest new information 43, and precedes the tail end of the second rank information 42 currently displayed in the display area 211. The new information 43 of is interrupted. That is, in the example shown from FIGS. 13 to 14, the display control unit 36 scrolls each second rank information 42 in the direction away from the display position of the latest new information 43 (N2), and is currently in the display area 211. At the end of the displayed second rank information 42, in this case, the second rank information 42 (W4) is followed by the new information 43 (N1). Then, the display control unit 36 scrolls and displays the new information 43 (N1) of the interrupted destination together with the second rank information 42.

According to this, when the previous new information 43 (N1) is interrupted and displayed by the second rank information 42 that has already been scrolled and displayed, the previous new information 43 (N1) is displayed without scrolling. It is possible to smoothly switch from to the scrolled display with a continuous appearance. Therefore, the user can easily recognize that the new information 43 (N1) that interrupts the scrolled second rank information 42 is the latest new information that has been displayed without being scrolled until immediately before. Become. This makes it easier for the user to pay attention to the new information 43 (N1) that is displayed by scrolling, that is, the new information 43 (N1) that is displayed without scrolling if there is no interrupt, and as a result. , It becomes possible to present more secure information.

Further, when the display control unit 36 interrupts and displays the previous new information 43 (N1 in the present embodiment) with other monitoring target information that has already been scrolled and displayed, in this case, the second rank information 42. , The above-mentioned new information 43 (N1 in this embodiment) is displayed in a mode different from the display mode of the second rank information 42 which is scroll-displayed. According to this, the user can at first glance distinguish between the new information 43 (N1 in the present embodiment) that interrupts the scroll display of the second rank information 42 and the second rank information 42 that has been scrolled and displayed from before. It becomes easier to do. Therefore, the user can easily grasp which of the second rank information 42 displayed by scrolling is the newly interrupted new information 43 (N1), and as a result, safer information. Presentation is possible.

(Third Embodiment)
Next, the third embodiment will be described with reference to FIGS. 17 to 21.
In the third embodiment, the scroll direction of the second rank information 42 is opposite to that of the second embodiment. That is, as shown from FIGS. 17 to 18, the display control unit 36 approaches the display position of the latest new information 43 (N1 in the present embodiment), in this case, upward as indicated by the arrow B. The 2 rank information 42 is scrolled. Then, when the monitoring target information acquisition unit 32 acquires the next new information 43 (N2 in the present embodiment), the display control unit 36 has a second display currently displayed in the display area 211 as shown in FIG. At the end of the rank information 42, in this case, after the second rank information 42 (W4), the new information 43 (N1 in the present embodiment) is interrupted. Then, as shown from FIGS. 19 to 21, the display control unit 36 scrolls and displays the new information 43 (N1) of the interrupted destination together with the second rank information 42.

According to this, when the previous new information 43 (N1) is interrupted and displayed by the second rank information 42 that has already been scrolled and displayed, the previous new information 43 (N1) is displayed without scrolling. It is possible to switch from to the scrolled display with a discontinuous appearance. Therefore, the user recognizes that the latest new information 43 (N2) displayed without scrolling has been switched from the previous new information 43 (N1) to the current latest new information 43 (N2). It will be easier. As a result, the user can easily pay attention to the latest new information 43 (N2), and as a result, more secure information can be presented.

It should be noted that the embodiment of the present invention is not limited to the embodiments described above and in the drawings, and various modifications and extensions can be made without departing from the gist thereof.
In each of the above embodiments, the display control unit 36 is premised on repeatedly performing the scroll display of the second rank information 42, but it is not always necessary to repeatedly perform the scroll display of the second rank information 42. For example, the display control unit 36 may display all the second rank information 42 by scrolling the second rank information 42 only once.

Further, in the second embodiment and the third embodiment, when the monitoring target information acquisition unit 32 acquires the next new information 43 (N2 in the above embodiment), the display control unit 36 shows in FIG. 14 or FIG.
