[0003] Japanese Patent Application Laid-Open No. 2021-190843

[0004] Conventional technology is based on the premise that the information provided to passengers is text data, and therefore cannot be applied when the information provided to passengers is in the form of images. For this reason, when the information provided to passengers is in the form of images, it is necessary to switch between images in multiple languages ​​depending on the time. In such cases, passengers may find it annoying to have to view images in languages ​​they do not understand.

[0005] Therefore, one or more aspects of the present disclosure aim to enable content to be referenced without the hassle of switching the display language.

[0006] A mobile terminal according to one aspect of the present disclosure is characterized in that it comprises: a display content editing unit that generates display content data by editing target content data that displays multiple images displayed in each of multiple languages ​​by switching between the multiple images one by one in order to convey the same content in each of the multiple languages, so as to display one image selected from the multiple images for the entire period for displaying the multiple images; and a display unit that displays content that includes at least the one image in accordance with the display content data.

[0007] A program according to one aspect of the present disclosure causes a computer to function as a display content editing unit that generates display content data by editing target content data that displays multiple images in multiple languages ​​one by one in order to convey the same content in each of the multiple languages, so that one image selected from the multiple images is displayed for the entire period for displaying the multiple images, and a display unit that displays content that includes at least the one image in accordance with the display content data.

[0008] A content display method according to one aspect of the present disclosure is characterized in that, in order to convey the same content in each of a plurality of languages, target content data is displayed by switching between a plurality of images displayed in each of the plurality of languages ​​one by one, and the target content data is edited so as to display one image selected from the plurality of images for the entire period for displaying the plurality of images, thereby generating display content data, and displaying content including at least the one image in accordance with the display content data.

[0009] According to one or more aspects of the present disclosure, content can be viewed without the hassle of switching the display language.

[0010] FIG. 1 is a block diagram schematically showing the configuration of a train communication system according to an embodiment; FIG. 2 is a block diagram schematically showing an example of the hardware configuration of a train communication device; (A) and (B) are schematic diagrams for explaining a first example of an editing process performed by a display content editing unit; (A) and (B) are schematic diagrams for explaining a second example of an editing process performed by a display content editing unit; FIG. 3 is a block diagram schematically showing an example of the hardware configuration of a mobile terminal; and FIG. 4 is a flowchart showing the operation of a mobile terminal.

[0011] 1 is a block diagram showing a schematic configuration of a train communication system 100 according to an embodiment. The train communication system 100 includes a train communication device 110 and a mobile terminal 130. The train communication device 110 is a communication device mounted on a train. For example, the train communication device 110 is mounted in each vehicle.

[0012] The train communication device 110 includes a first communication unit 111 , a second communication unit 112 , a memory unit 113 , and a control unit 114 .

[0013] The first communication unit 111 is a device-side wireless communication unit that transmits and receives data wirelessly. For example, the first communication unit 111 transmits distribution data to the mobile terminal 130. Specifically, the first communication unit 111 broadcasts using a BLE (Bluetooth Low Energy) advertisement and transmits the distribution data to the connected mobile terminal 130.

[0014] The second communication unit 112 is an in-train communication unit that connects to an in-train network (not shown) and communicates with other devices (not shown) in the in-train network. For example, the second communication unit 112 receives source data from other devices in the in-train network, including train-specific information such as the train formation number and car number, and information on the train status such as the train's running position, the train's running or stopped state, and the opening and closing of the train doors, for each car.

[0015] The storage unit 113 stores data and programs necessary for processing by the train communication device 110. For example, the storage unit 113 stores train-specific information such as the train formation number of the train in which the train communication device 110 is installed and the car number of the car in which the train communication device 110 is installed.

[0016] The control unit 114 controls the processing in the train communication device 110. For example, the control unit 114 extracts only information related to the car in which the train communication device 110 is installed from the distribution source data received by the second communication unit 112, and stores the extracted information in the storage unit 113. Then, the control unit 114 generates distribution data by referring to the information stored in the storage unit 113.

[0017] For example, the distribution data includes train-specific information such as the train formation number of the train in which the train communication device 110 is installed and the car number of the car in which the train communication device 110 is installed, as well as information regarding the train's status such as the train's running position, the train's running or stopped status, and the opening and closing of the train doors.

[0018] Then, the control unit 114 transmits the generated distribution data to the mobile terminal 130 via the first communication unit 111 .

[0019] The train communication device 110 described above can be realized by, for example, a computer 10 as shown in Fig. 2. The computer 10 includes a storage 11 such as a hard disk drive (HDD) and a solid state drive (SSD), a memory 12, a processor 13 such as a central processing unit (CPU), a first communication I / F 14 which is a wireless communication I / F (Interface) using radio waves, and a second communication I / F 15 which is a communication I / F such as a network interface card (NIC).

[0020] For example, the first communication unit 111 can be realized by the first communication I / F 14. The second communication unit 112 can be realized by the second communication I / F 15. The storage unit 113 can be realized by the storage 11 or the memory 12. The control unit 114 can be realized by the processor 13 loading a program stored in the storage 11 into the memory 12 and executing the program.

[0021] The program may be downloaded to the storage 11 from a recording medium (not shown) via a reader / writer (not shown) or from a network via the second communication I / F 15, and then loaded onto the memory 12 and executed by the processor 13. Alternatively, the program may be directly loaded onto the memory 12 from a recording medium via a reader / writer or from a network via the second communication I / F 15, and then executed by the processor 13. In other words, the program may be provided by a computer program product such as a recording medium.

[0022] Returning to FIG. 1, the mobile terminal 130 includes a communication unit 131 , a display unit 132 , a storage unit 133 , and a control unit 136 .

[0023] The communication unit 131 is a terminal-side wireless communication unit that transmits and receives data wirelessly. The display unit 132 displays content.

[0024] The storage unit 133 stores data and programs necessary for processing in the mobile terminal 130. The storage unit 133 includes a setting storage unit 134 and a display content storage unit 135.

[0025] The setting storage unit 134 stores setting information indicating the contents set in the mobile terminal 130. Here, the setting information indicates at least a preferred language, which is a language used by the user of the mobile terminal 130, and an alternative language, which is a language used instead when the language used by the user is not used in the content data.

[0026] The display content storage unit 135 stores a plurality of content data to be displayed on the mobile terminal 130. For example, one piece of content data is selected from the plurality of content data in accordance with distribution data received by the communication unit 131.

[0027] The multiple content data includes at least one content data having multiple images that are displayed one by one to convey the same content in multiple languages, and an animation definition for switching between the multiple images. Each of the multiple images is associated with a corresponding one of the multiple display languages. The multiple images are displayed at predetermined positions and with predetermined sizes. Here, the language used to convey the same content in multiple images is also referred to as the display language.

[0028] An animation definition is data that describes how to change the position, size, rotation angle, color, opacity, etc. of an image over time. For example, by changing the opacity of multiple images using the animation definition, it is possible to switch between displaying and hiding each of multiple images.

[0029] The control unit 136 controls the processing in the mobile terminal 130. The control unit 136 includes an information extraction unit 137, a display content selection unit 138, and a display content editing unit 139.

[0030] The information extraction unit 137 extracts train-specific information and information about the train's status from the distribution data. The extracted information is provided to the display content selection unit 138.

[0031] The display content selection unit 138 refers to the information provided by the information extraction unit 137 and selects one piece of content data as target content data from the plurality of content data stored in the display content storage unit 135, depending on the car number and train status in which the user of the mobile terminal 130 is riding. The target content data is provided to a display content editing unit 139.

[0032] The display content editing unit 139 generates display content data by editing target content data, which displays multiple images in multiple languages ​​one by one to convey the same content in each of the multiple languages, so that one image selected from the multiple images is displayed throughout the entire period for displaying the multiple images. Here, it is assumed that each of the multiple images is displayed to convey the same content in each of the multiple languages. Here, the display content editing unit 139 selects an image written in a language that the user of the mobile terminal 130 can easily understand as the single image. For example, if a preferred language preset as the language used by the user of the mobile terminal 130 is included in the multiple languages ​​corresponding to the multiple images included in the target content data, the display content editing unit 139 selects an image from the multiple images to be displayed in the preferred language as the single image. On the other hand, if the preferred language is not included in the multiple languages, the display content editing unit 139 selects an image from the multiple languages ​​to be displayed in a language preset as an alternative language in the mobile terminal 130 as the single image.

[0033] Specifically, the display content editing unit 139 receives the target content data from the display content selection unit 138 and determines whether or not the target content data needs to be edited. For example, if the target content data includes multiple images displayed in multiple display languages, the display content editing unit 139 determines that the target content data needs to be edited.

[0034] When the target content data needs to be edited, the display content editing unit 139 identifies the used language and the alternative language from the setting information stored in the setting storage unit 134. Next, from a plurality of images that are displayed one by one in order to convey the same content in each of a plurality of languages ​​included in the target content data, the display content editing unit 139 identifies one image corresponding to a display language that matches the used language, or, if there is no display language that matches the used language, one image corresponding to a display language that matches the alternative language.

[0035] Then, the display content editing unit 139 edits the target content data so that a portion where a plurality of images are displayed by switching between them is displayed with the single specified image, thereby generating display content data. Here, the display content editing unit 139 can generate display content data by rewriting the single specified image in the animation definition to a table throughout the entire period where a plurality of images are displayed by switching between them, and rewriting all images among the plurality of images other than the single specified image to be hidden throughout the entire period.

[0036] On the other hand, if the target content data does not need to be edited, the display content editing unit 139 sets the selected content data as the display content data. The display content data as described above is provided to the display content selection unit 138.

[0037] 3A and 3B are schematic diagrams illustrating a first example of editing processing performed by the display content editing unit 139. First, as shown in Fig. 3A, it is assumed that the target content data includes image A, whose display language is Japanese, image B, whose display language is English, and image C, whose display language is Chinese.

[0038] In the target content data, images A, B, and C are displayed in this order, switching between them. Note that images A, B, and C are each displayed for only one second. This allows users who can understand Japanese, English, and Chinese to understand the content to be communicated using only one of images A, B, and C.

[0039] However, a user who can understand Japanese but cannot understand English or Chinese is required to understand the content that image A is trying to convey within the one second that image A is displayed, and the period during which images B and C are displayed is wasted time.

[0040] In such a case, in this embodiment, if Japanese is set as the working language of the mobile terminal 130, as shown in Fig. 3(B), image A is displayed in place of images B and C during the period for displaying images B and C. Therefore, even a user who can understand Japanese but cannot understand English or Chinese can be ensured to have enough time to fully grasp the communication content from image A, and the possibility that such a user will miss image A due to, for example, looking away can be reduced.

[0041] 4A and 4B are schematic diagrams illustrating a second example of the editing process performed by the display content editing unit 139. As shown in Fig. 4A, the target content data includes, similarly to Fig. 3A, image A whose display language is Japanese, image B whose display language is English, and image C whose display language is Chinese.

[0042] In Figures 3 (A) and (B), it is assumed that one of the display languages ​​included in the content data is set as the language used on the mobile terminal 130, but there are cases where the language used on the mobile terminal 130 does not match any of the display languages ​​included in the content data, for example, the language used on the mobile terminal 130 is German, etc.

[0043] In such a case, if English is set as an alternative language for the mobile terminal 130, as shown in Fig. 4(B), image B is displayed in place of images A and C during the period for displaying images A and C. Therefore, a user who cannot understand Japanese or Chinese but can understand English to some extent can have enough time to fully understand the content of the communication from image B.

[0044] 1 , the display content selection unit 138 receives display content data from the display content editing unit 139, generates display content from the display content data, and displays the display content on the display unit 132. This allows the display unit 132 to display content including at least one image selected in the user's language or an alternative language in accordance with the display content data.

[0045] The mobile terminal 130 described above can be realized, for example, by a computer 20 as shown in Fig. 5. The computer 20 includes a storage device 21 such as an HDD or SSD, a memory 22, a processor 23 such as a CPU, a communication I / F 24, an input I / F 25, and a display 26.

[0046] For example, the communication unit 131 can be realized by the communication I / F 24. The display unit 132 can be realized by the display 26. The storage unit 133 can be realized by the storage 21 or the memory 22. The control unit 136 can be realized by the processor 23 loading a program stored in the storage 21 into the memory 22 and executing the program.

[0047] The program may be downloaded to the storage 21 from a recording medium (not shown) via a reader / writer (not shown) or from a network via the communication I / F 24, and then loaded onto the memory 22 and executed by the processor 23. Alternatively, the program may be directly loaded onto the memory 22 from a recording medium via the reader / writer or from a network via the communication I / F 24, and then executed by the processor 23. In other words, the program may be provided by a computer program product such as a recording medium.

[0048] 6 is a flowchart showing the operation of the mobile terminal 130. First, the communication unit 131 receives distribution data from the train communication device 110 (S10). The received distribution data is provided to the information extraction unit 137.

[0049] The information extraction unit 137 analyzes the distribution data provided by the communication unit 131 to extract train-specific information and information related to the train's status from the distribution data (S11). The extracted information is provided to the display content selection unit 138.

[0050] The display content selection unit 138 refers to the information provided by the information extraction unit 137 and selects, as target content data, one piece of content data corresponding to the car number and train status in which the user of the mobile terminal 130 is riding, from the plurality of content data stored in the display content storage unit 135 (S12). The target content data is provided to the display content editing unit 139.

[0051] The display content editing unit 139 determines whether the target content data includes multiple images that are switched between and displayed to convey the same content in multiple display languages ​​(S13). For example, if the target content data is associated with multiple display languages ​​and includes multiple images displayed in the same area, the display content editing unit 139 determines that the target content data includes multiple images. If the target content data includes multiple images (Yes in S13), the process proceeds to step S14. If the target content data does not include multiple images (No in S13), the process proceeds to step S16. Note that if the result in step S13 is No, the display content editing unit 139 does not edit the target content data, but provides the target content data to the display content selection unit 138 as display content data.

[0052] In step S14 , the display content editing unit 139 identifies the language to be used and the alternative language from the setting information stored in the setting storage unit 134 .

[0053] Next, the display content editing unit 139 edits the target content data by replacing images displayed in languages ​​other than the used language and the representative language with images displayed in the used language or the representative language, thereby generating display content data (S15). The display content data is configured so that images displayed in the used language or the representative language are displayed even during periods when images displayed in languages ​​other than the used language and the representative language were scheduled to be displayed. The generated display content data is provided to the display content selection unit 138, and the process proceeds to step S16.

[0054] In step S16 , the display content selection unit 138 receives the display content data from the display content editing unit 139 , generates display content from the display content data, and causes the display unit 132 to display the display content.

[0055] As described above, according to this embodiment, the user of the mobile terminal 130 can view images in one display language that is easy for the user to understand for a sufficient period of time without having to switch between multiple images corresponding to multiple display languages.

[0056] For simplicity's sake, a group is defined as a set of images that are displayed one by one to convey the same content in multiple languages. While the above-described embodiment illustrates a case in which content data includes one group, the content data may also include multiple groups. In such a case, the display content editing unit 139 may recognize multiple images with the same display position and size as a group, or, if the content data includes identification information for identifying the group, may use the identification information to recognize the multiple images as a group.

[0057] Furthermore, the display content editing unit 139 may operate as follows when the target content data is configured to display, in the same frame, a plurality of images corresponding to a plurality of display languages ​​that are switched one by one, and a single image corresponding to a single display language (hereinafter also referred to as a fixed display language) that is not switched and is displayed. Note that, here, it is assumed that the plurality of images and the single image convey the same content. If the fixed display language is the working language, the display content editing unit 139 may edit the target content data so that only the single image is displayed, or may use the target content data as is without editing it. On the other hand, if the fixed display language is not the working language, the single image may not be displayed, and the target content data may be edited as described above.
