DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Embodiment 1 FIG. 1 is a diagram showing an example of the configuration of a guidance control device 1 according to the first embodiment. The guidance control device 1 is mounted on, for example, a server (not shown). The guidance control device 1 is communicably connected to an information output device 3 via a network. The guidance control device 1 and the information output device 3 constitute a guidance control system 100. The guidance control device 1 is also communicably connected to a transport system 2 via a network. The transport system 2 manages the transport of moving objects. The transport system 2 is owned by, for example, a transport management company or a railway company.

[0010] The guidance control device 1 acquires information on the operation of a moving object from the operation system 2 (hereinafter referred to as "operation information"), and judges whether or not a predetermined event has occurred based on the acquired operation information of the moving object. In the first embodiment, an "event" refers to an event that occurs suddenly, or an event for which users should prepare in advance. A sudden event is specifically an operational disruption of a moving object, etc. An event for which users should prepare in advance is, in other words, an event in which a state occurs for which users should ensure safety, specifically an entry of a moving object into a station, etc. These predetermined events are hereinafter simply referred to as "events". Events are required to be announced to users promptly and in a manner that allows them to understand the details. The guidance control device 1 determines whether an event has occurred based on the operation information, and when it determines that an event has occurred, it notifies the user of the occurrence of the event and its details. Specifically, the guidance control device 1 generates information for informing the user of the occurrence of the event and its details (hereinafter referred to as "guidance information"), and displays the generated guidance information on a display unit 31 (see FIG. 2 described later) provided in the information output device 3. In the first embodiment, an "event" is also called a "notification target event" because it becomes a subject of guidance by the guidance control device 1 when it occurs.

[0011] The operation information acquired by the guidance control device 1 from the operation system 2 includes information on operation schedules, operation status, operation disruptions, and the like. The operation schedule includes, for example, train or vehicle numbers, train or vehicle types, approach modes to boarding and alighting points, scheduled arrival times at boarding and alighting points, scheduled departure times from boarding and alighting points, entering boarding and alighting points, number of trains, etc. The operation status includes the presence or absence of delays, delay time, the current position of the mobile object, changes in the operation status, congestion status of the mobile object, etc. The current position of the mobile object is indicated, for example, by the name of the boarding / alighting platform (station name, etc.) where the mobile object is currently stopped or the name of the boarding / alighting platform section (station section name, etc.) through which the mobile object is currently traveling. Information regarding changes in the operation status includes, for example, a change in the position of the mobile object when it enters the station (for example, far → close → arrived). Operational disruptions include train or vehicle troubles (including, for example, train or vehicle breakdowns or inspections), personal injury accidents, natural disasters, various accidents, overhead line troubles, and the like. The information on the operation disruption includes not only the fact that the operation disruption has occurred, but also information indicating the stage of the disruption over time (e.g., occurrence, response, or recovery). The information on the operation disruption may also include information indicating the reason for the disruption, the response, or the prospect of recovery in the future.

[0012] Here, the information output device 3 in the first embodiment will be described. FIG. 2 is a diagram for explaining an outline of an example of a configuration of the information output device 3 according to the first embodiment. FIG. 2 is a front view of the information output device 3. As shown in FIG. 2, the information output device 3 includes a main body 33, a display unit 31 provided on the main body 33, and a lighting unit 32 provided on the main body 33. The display unit 31 is a video display device such as a liquid crystal display. The display unit 31 may be a digital signage. In the first embodiment, the display unit 31 is assumed to be a digital signage. The lighting unit 32 is an illumination device including an LED (Light Emitting Diode) etc. The lighting unit 32 is provided around the display unit 31.

[0013] The guidance control device 1 displays the generated guidance information on the display unit 31. Furthermore, when the guidance control device 1 displays the guidance information on the display unit 31, it turns on the lighting unit 32. Note that, in this context, the guidance control device 1 causing the guidance information to be displayed on the display unit 31 means giving an instruction to display it. Furthermore, the guidance control device 1 turning on the lighting unit 32 means giving an instruction to turn it on. Therefore, "when the guidance control device 1 causes the guidance information to be displayed on the display unit 31, it turns on the lighting unit 32" means that the guidance control device 1 gives an instruction to the display unit 31 to display the guidance information and gives an instruction to the lighting unit 32 to turn it on, and does not limit the order of the actual display and the actual lighting, and the order of the actual display and the actual lighting is not important.

[0014] 2, the main body 33 is a housing, but the shape of the main body 33 is not limited. It is sufficient that the information output device 3 includes the display unit 31 and the lighting unit 32. 2, the lighting unit 32 is provided on the upper and lower sides of the display unit 31 when the display unit 31 is viewed from the front with the information output device 3 installed, but this is merely an example. For example, the lighting unit 32 may be provided only on the upper side or only on the lower side of the display unit 31 when the display unit 31 is viewed from the front with the information output device 3 installed, or may be provided on the right or left side of the display unit 31. The lighting unit 32 may be provided around the display unit 31. The surroundings of the display unit 31 are assumed to be, for example, a place close to the display unit 31 so that the user can recognize that the display on the display unit 31 and the lighting of the lighting unit 32 are associated with each other.

[0015] The guidance control device 1 controls the display of guidance information on the display unit 31 and the lighting of the lighting unit 32 in the information output device 3 based on operation information acquired from the operation system 2. In the first embodiment, the guidance information displayed by display unit 31 is information that notifies a user who is in a place where the guidance information is visible of the occurrence and details of the event to be notified. The details of the guidance control device 1 will be described later. Also, the specific contents of the guidance information will be described later with a specific example. 1, the guidance control system 100 is shown to have one information output device 3, but this is merely an example. In the guidance control system 100, a plurality of information output devices 3 may be installed at appropriate locations. The guidance control device 1 may also control the display of different guidance information on the display unit 31, or control the lighting of different information on the lighting unit 32, for the plurality of information output devices 3.

[0016] In the following, in the first embodiment, as an example, the moving body is a train, and the information output device 3 is provided at a platform at a station where the train can arrive and depart. The platform at a station includes various facilities such as a platform, platform fences, platform doors, a wall along the track on the opposite side of the platform from the track, a roof, or a ceiling. Additionally, the term "users" includes passengers using trains and station staff. In the following first embodiment, as an example, the event for which information is to be provided is a train service disruption or a train entering a station.

[0017] The operation system 2 here is, for example, a so-called train control and management system (TCMS). The integrated train management system includes a traffic control server that manages train operations, and a signal transmitter. The traffic management server holds information about train schedules, such as train timetables, scheduled arrival times at or departure times from stations for each train, and information about train operation conditions, such as train positions at a given time or the presence or absence of delays. The integrated train management system manages multiple trains in operation, and centrally manages data related to the monitoring and control of various devices, such as motors and brakes, installed in each car of the multiple trains from the driver's cab. In addition, the integrated train management system collects and stores information on various types of troubles occurring in train operations, such as operational disruptions. The signal transmitter outputs operation information related to train operation, which is centrally controlled in the driver's cab, to the guidance control device 1.

[0018] An example of the configuration of the guidance control device 1 according to the first embodiment will be described. As shown in FIG. 1, the guidance control device 1 includes an operation information acquisition unit 11, a determination unit 12, a presentation information generation unit 13, a display control unit 14, and an illumination control unit 15.

[0019] The operation information acquisition unit 11 acquires operation information from the operation system 2. The operation information acquisition unit 11 outputs the acquired operation information to the determination unit 12.

[0020] The operation information acquisition unit 11 may output the acquired operation information not only to the determination unit 12 but also to a station management system (not shown), for example. The station management system manages information that should be shared by station staff at each station. The information that station staff should share includes operation information. Based on the information it manages, the station management system outputs information that should be notified to each station staff member (hereinafter referred to as "notification information for station staff") to a PC (Personal Computer) installed in the station's control room or the like, or to a mobile device carried by each station staff member. The notification information for station staff includes, for example, information notifying the occurrence and details of an event that requires notification, and information instructing the execution of an in-station announcement. The station management system can output notification information for station staff individually to multiple PCs installed in the station's control room or the like, or multiple mobile devices carried by each station staff member. The station management system may acquire operation information directly from the operation system 2 separately, not via the operation information acquisition unit 11.

[0021] The determination unit 12 determines whether or not a guidance target event has occurred based on the operation information acquired by the operation information acquisition unit 11. As described above, the operation information includes information on the operation schedule, operation status, operation disruptions, etc. Based on the operation information, the determination unit 12 can determine whether an event to be notified about, i.e., whether an operation disruption has occurred or whether a train is entering the station. When the determination unit 12 determines that a notification target event has occurred, it outputs information indicating that the notification target event has occurred (hereinafter referred to as "event occurrence information") together with operation information to the presentation information generation unit 13. Note that the event occurrence information includes information indicating whether the occurring notification target event is an operation disruption or a train entering the station.

[0022] When the judgment unit 12 judges that an event to be notified has occurred, in other words, when event occurrence information is output from the judgment unit 12, the presentation information generation unit 13 generates guidance information to inform the user of the occurrence and details of the event to be notified.

[0023] Here, the guidance information generated by the presentation information generating unit 13 will be described with a concrete example. For example, assume that an operation failure occurs as a notification target event, and the content of the failure is a fatal accident. In this case, operation information indicating that an operation failure, more specifically, an occurrence of a fatal accident, has occurred is transmitted from the operation system 2 to the guidance control device 1. The determination unit 12 determines that a train operation failure has occurred, and outputs the event occurrence information and the operation information to the presentation information generation unit 13. When the event occurrence information is output from the determination unit 12, the presentation information generation unit 13 grasps that an operation disorder, more specifically, a personal injury accident, has occurred. The event occurrence information includes information indicating the details of the operation disorder, such as a personal injury accident, and the presentation information generation unit 13 may grasp that a personal injury accident has occurred from the event occurrence information, or may grasp the occurrence of an operation disorder from the event occurrence information and grasp the details of the operation disorder from the operation information output together with the event occurrence information.

[0024] When the presentation information generation unit 13 grasps the occurrence of an event to be notified and its details, i.e., in this case, the occurrence of an operational disruption and the details of the incident being a personal injury accident, from the event occurrence information or operation information, it generates guidance information to inform the driver that a personal injury accident has occurred.

[0025] The guidance information is information that displays a message such as "Injury accident has occurred." The presentation information generating unit 13 may generate the guidance information according to, for example, a preset rule (hereinafter referred to as "rule for generating guidance information"). For example, in the rule for generating guidance information, the occurring event to be notified and its contents are associated with a standard phrase for the message or a display format, etc., of the guidance information, and a rule for generating the guidance information. The rule for generating guidance information is generated in advance by an administrator or the like, and is stored in a storage unit (not shown). The storage unit is provided in a location that can be referenced by the presentation information generating unit 13. Here, it is assumed that the guidance information generating rules correspond to an operation disruption and a personal injury accident, which is the content of the operation disruption, and a rule that a message stating "personal injury accident has occurred" is used as guidance information. The presentation information generating unit 13 compares the event occurrence information or the operation information with the guidance information generating rules, and generates guidance information that displays a message saying "A personal injury accident has occurred."

[0026] Furthermore, the presentation information generating unit 13 assigns to the generated guidance information, for example, a category (hereinafter referred to as a "display category") indicating the event to be notified about and its contents in the guidance information. Specifically, as described above, when the guidance information is information for displaying a message saying "Injury accident has occurred," the presentation information generating unit 13 assigns to the guidance information, for example, a display category "1 (operational disorder) 1 (injury accident occurring)" indicating the event to be notified about and its contents in the guidance information. Note that this is merely one example, and the guidance information may be information that allows identification of the event to be notified about and its contents in the guidance information.

[0027] As another specific example, assume that a train arrival occurs as an event for which guidance is required, and that the train is arriving at track number △. In this case, the operation system 2 transmits to the guidance control device 1 the train operation schedule, more specifically, operation information indicating, for example, that a train is entering, the boarding and alighting station where the train will enter, the train type, the entry mode, and the scheduled arrival time, and the judgment unit 12 judges that a train will enter the station and outputs the event occurrence information and operation information to the presentation information generation unit 13. When the event occurrence information is output from the determination unit 12, the presentation information generation unit 13 grasps that a train is about to arrive at the station.

[0028] When the presentation information generation unit 13 grasps the occurrence of an event to be notified and its details from the event occurrence information or operation information, that is, in this case, the occurrence of a train entering the station and its details (a train entering platform △), it generates guidance information to inform the user that a train is entering the station.

[0029] Here, the rules for generating guidance information stipulate that the entry of a train and the details of that entry, namely entry into platform △, should be associated with the message "A train will soon arrive at platform △. Please stand inside the white line" as guidance information. The presentation information generating unit 13 compares the event occurrence information or operation information with the guidance information generating rules, and generates guidance information that displays a message such as "A train will soon arrive at platform △. Please stand behind the white line." Note that the presentation information generating unit 13 sets the platform number where the train is arriving to the "△" in "platform △."

[0030] The presentation information generating unit 13 also assigns a display category to the generated guidance information. Specifically, as described above, when the guidance information is information for displaying a message such as "A train will soon arrive at platform △. Please stand behind the white line," the presentation information generating unit 13 assigns, for example, a display category "2 (arriving) △ (platform △)" to the guidance information, which indicates the event to be notified about in the guidance information and its content.

[0031] After generating the guidance information, the presentation information generation unit 13 outputs the generated guidance information to the display control unit 14 and the lighting control unit 15. The presentation information generation unit 13 outputs operation information to the display control unit 14 and the lighting control unit 15 together with the guidance information.

[0032] The display control unit 14 causes the display unit 31 to display the guidance information generated by the presentation information generation unit 13 . The position on the display unit 31 at which the display control unit 14 displays the guidance information is determined in advance depending on the content of the guidance information. For example, information (hereinafter referred to as "display conditions") that associates the display classification given to the guidance information with the position on the display unit 31 at which the guidance information is to be displayed is generated in advance and stored in a storage unit (not shown). The position on the display unit 31 at which the guidance information is to be displayed is represented, for example, by coordinates on the display unit 31. For example, the display conditions may further be associated with the display size of the guidance information. The display position and size of the guidance information on the display unit 31 may be set in advance and fixedly, regardless of the content of the guidance information.

[0033] When the display control unit 14 causes the display unit 31 to display guidance information, the lighting control unit 15 causes the lighting unit 32 to light up. The lighting control unit 15 may know that the display control unit 14 has caused the display unit 31 to display the guidance information, in other words, that the display control unit 14 has instructed the display unit 31 to display the guidance information, by, for example, acquiring the guidance information from the presentation information generating unit 13. Also, for example, the display control unit 14 may output a signal to the lighting control unit 15 when it instructs the display unit 31 to display the guidance information, and the lighting control unit 15 may know that the display control unit 14 has instructed the display unit 31 to display the guidance information when the signal is output from the display control unit 14. Note that an arrow from the display control unit 14 to the lighting control unit 15 is omitted in FIG. 1. The color in which the lighting control unit 15 lights up the lighting unit 32 is, for example, determined in advance.

[0034] Here, Figure 3 is a diagram for explaining an example of the appearance of information output device 3 in embodiment 1, in which display control unit 14 displays guidance information on display unit 31, and when display control unit 14 displays the guidance information on display unit 31, lighting control unit 15 lights up lighting unit 32. In FIG. 3, as an example, the guidance information is information that displays a message saying "Injury accident has occurred." 3, when guidance information is output from the presentation information generating unit 13, the display control unit 14 causes the display unit 31 of the information output device 3 to display a message saying "Injury accident has occurred." The display unit 31 displays the message saying "Injury accident has occurred" according to the control of the display control unit 14. Furthermore, the lighting control unit 15 turns on the lighting unit 32. The lighting unit 32 turns on under the control of the lighting control unit 15.

[0035] The display control unit 14 causes the display unit 31 to display guidance information, and thus the guidance control device 1 can inform the user of the occurrence and details of the event to be notified. The user can understand the occurrence and details of the event to be notified by looking at the display unit 31. In the example using Fig. 3 described above, the user can understand by looking at the display unit 31 that an operation disruption has occurred and that the operation disruption is due to an accident resulting in injury or death. Here, even if the display control unit 14 displays the occurrence of the event to be notified in a form that allows the user to understand the contents, the user may not notice it. In response to this, the lighting control unit 15 lights up the lighting unit 32 when the display control unit 14 displays the guidance information on the display unit 31, so that the guidance control device 1 can alert the user and guide the user's gaze to the display unit 31. This allows the guidance control device 1 to allow the user to understand the occurrence and contents of the event to be notified. The event to be notified is an unexpected event that occurs suddenly and is not expected by the user, or an event in which a state occurs in which the user must ensure safety, and it is required that the user is notified of the event particularly quickly and in a manner that allows the user to understand the contents. As described above, the guidance control device 1 can notify the occurrence and contents of the event to be notified by display and lighting so that the user can understand the occurrence and contents of the event to be notified without overlooking it.

[0036] Furthermore, the display control unit 14 displays guidance information on the display unit 31 in a form that indicates the content of the event that is being notified (in the above example, an accident resulting in injury or death), rather than merely indicating that some event that is being notified has occurred, thereby enabling the user to quickly understand the content of the event that is being notified. For example, if a able-bodied person can understand that some event that is being notified has occurred, they may be able to ask station staff or other people around them about the content. However, for example, a visually impaired person cannot ask people around them about the content. By having the display control unit 14 display guidance information on the display unit 31 in a form that makes it possible to understand the content of the occurring event to be notified about, the guidance control device 1 can allow users, including those who are hearing impaired, to understand the occurrence and content of the event to be notified about.

[0037] In the above example, the operation disruption is an accident resulting in injury or death. However, the operation disruption may include, for example, a response to the operation disruption. For example, in the guidance control device 1, the presentation information generating unit 13 may generate, as guidance information, a message that conveys the current stage of the response status to an operation failure over time. The response status stage may be, for example, occurrence, response in progress, or recovery. Over time, the response status to an operation failure changes in the order of occurrence, response in progress, and recovery. For example, when a fatal accident occurs and the response status is "responding," the presentation information generation unit 13 generates guidance information that displays the text "Failure to Cause Accident Occurred" and "Currently Responding" according to the rules for generating guidance information. The determination unit 12 can determine that a fatal accident has occurred and that the response status is "currently being handled" based on the operation information. The determination unit 12 may output event occurrence information indicating that the operation disruption is a fatal accident and that the operation is currently being handled to the presentation information generation unit 13. The presentation information generation unit 13 may also determine that the operation disruption is a fatal accident and that the operation is currently being handled from the operation information. Then, the display control unit 14 displays the words "Currently responding" below the words "Injury accident occurring" on the display unit 31 as shown in FIG. 3 according to the display conditions, for example.

[0038] The operation of the guidance control device 1 according to the first embodiment will be described. FIG. 4 is a flowchart for explaining the operation of the guidance control device 1 according to the first embodiment. For example, when the power supply to the guidance control device 1 is turned on or when an instruction to start the operation is received from an administrator or the like, the guidance control device 1 starts the operation as shown in the flowchart of Fig. 4. For example, the guidance control device 1 repeats the operation as shown in the flowchart of Fig. 4 until the power supply to the guidance control device 1 is turned off or an instruction to end the operation is received from an administrator or the like. A manager or the like inputs an operation start instruction or an operation end instruction from a PC installed in, for example, a station control room. The control unit (not shown) of the guidance control device 1 receives the operation start instruction and starts the operations of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, and the lighting control unit 15. The control unit also receives an operation end instruction and ends the operations of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, and the lighting control unit 15.

[0039] The operation information acquisition unit 11 acquires operation information from the operation system 2 (step ST10). The operation information acquisition unit 11 outputs the acquired operation information to the determination unit 12.

[0040] The determination unit 12 determines whether or not a guidance target event has occurred based on the operation information acquired by the operation information acquisition unit 11 in step ST10 (step ST20). When it is determined that a guidance target event has occurred ("YES" in step ST20), the determination unit 12 outputs event occurrence information to the presentation information generation unit 13 together with the operation information.

[0041] If the determination unit 12 determines that a guidance target event has not occurred ("NO" in step ST20), the operation of the guidance control device 1 returns to the processing of step ST10.

[0042] If the judgment unit 12 judges in step ST20 that an event to be notified has occurred (if "YES" in step ST20), in other words, if the judgment unit 12 outputs event occurrence information, the presentation information generation unit 13 generates guidance information to inform the user of the occurrence and details of the event to be notified (step ST30). After generating the guidance information, the presentation information generation unit 13 outputs the generated guidance information to the display control unit 14 and the lighting control unit 15.

[0043] The display control unit 14 causes the display unit 31 to display the guidance information generated by the presentation information generation unit 13 in step ST30 (step ST40).

[0044] When the display control unit 14 causes the display unit 31 to display the guidance information in step ST40, the lighting control unit 15 turns on the lighting unit 32 (step ST50).

[0045] In this way, the guidance control device 1 according to the first embodiment acquires operation information related to train operation, and determines whether or not a notification target event has occurred based on the acquired operation information. When it is determined that a notification target event has occurred, the guidance control device 1 generates guidance information that provides information about the occurrence and details of the notification target event, and displays the generated guidance information on the display unit 31 and turns on the lighting unit 32. This allows the guidance control device 1 to provide the user with information about the event to be notified promptly and in a manner that allows the user to understand the details of the event.

[0046] <Variation (1)> In the above-described first embodiment, the lighting control unit 15 may determine the operation status of the train based on the operation information, and change the lighting cycle or lighting color of the lighting unit 32 according to the determined operation status.

[0047] For example, the lighting control unit 15 can change the lighting cycle of the lighting unit 32 in response to a change in the operating situation. A specific example will be described below. For example, suppose that a train entry occurs as a guidance target event, and the content of the train entry is entry into platform △. In this case, the operation system 2 transmits to the guidance control device 1 train operation schedules, more specifically, operation information indicating that a train will enter, the platform into which the train will enter, the train type, the entry mode, and the estimated arrival time, and the like. The determination unit 12 determines that a train will enter the platform, and outputs event occurrence information and operation information to the presentation information generation unit 13. When the event occurrence information is output from the determination unit 12, the presentation information generation unit 13 grasps the occurrence of the train entry and its content (the train will enter platform △) from the event occurrence information or the operation information, and generates guidance information that displays a message such as, for example, "A train will arrive at platform △ shortly. Please stand behind the white line." When the display control unit 14 causes the display unit 31 to display the above-mentioned guidance information, the lighting control unit 15 turns on the lighting unit 32. At this time, the lighting control unit 15 changes the lighting cycle of the lighting unit 32 depending on, for example, the train's arrival status, specifically, the distance between the train and the platform of the station where the train arrives. For example, the lighting control unit 15 can grasp the change in the position of the train when it arrives, more specifically, whether it is "far", "near", or "arrived", from the operation status information included in the operation information. For example, the lighting control unit 15 slows down the lighting cycle of the lighting unit 32 when the distance between the train and the station platform is "far," and speeds up the lighting cycle of the lighting unit 32 when the distance between the train and the station platform is "close" compared to when the distance between the train and the station platform is "far," and when the train arrives at the station, speeds up the lighting cycle even further and causes the lighting unit 32 to flash.

[0048] For example, the lighting control unit 15 may change the lighting color of the lighting unit 32 in response to a change in the operating situation. In the above specific example, the lighting control unit 15 lights up the lighting unit 32 when the display control unit 14 causes the display unit 31 to display guidance information, and may change the lighting cycle of the lighting unit 32 depending on the train's arrival status, specifically, the distance between the train and the platform where the train arrives. For example, the lighting control unit 15 changes the lighting color of the lighting unit 32 to white when the distance between the train and the platform where the train arrives is "far," changes the lighting color of the lighting unit 32 to yellow when the distance between the train and the platform where the train arrives is "close," and changes the lighting color of the lighting unit 32 to red when the train arrives at the station. Also, for example, the lighting control unit 15 may change both the lighting cycle and the lighting color of the lighting unit 32 in response to a change in the operating situation.

[0049] In this way, the lighting control unit 15 determines the operation status of the train based on the operation information, and changes the lighting cycle or lighting color of the lighting unit 32 according to the determined operation status, so that the guidance control device 1 can provide the user with guidance about the event to be notified more visually and quickly, and in a manner that allows the user to understand the contents of the event. By changing the lighting cycle or lighting color of the lighting unit 32, the guidance control device 1 can provide the user with guidance about the operation status so that the user can intuitively understand the change in the operation status.

[0050] <Variation (2)> In the above-described first embodiment, an example of the guidance information has been described in which the guidance information displays a message such as "Injury accident has occurred." This is merely one example, and the guidance information may be information that provides information about the occurrence and details of the event to be notified using a diagram. That is, in the above-described first embodiment, the presentation information generating unit 13 may generate guidance information that provides information about the occurrence and details of the event to be notified using a diagram.

[0051] In this case, for example, in the guidance information generating rule, the event to be notified and its contents are associated with information including information showing a diagram as information to be displayed. For example, as a rule for generating guidance information when a personal injury accident has occurred, a rule is associated that the information indicating the occurring event to be notified, "operational disorder", and its contents, "personal injury accident", a message "personal injury accident has occurred", and a route map in which the station in which the personal injury accident has occurred is highlighted, as guidance information. The presentation information generating unit 13 generates, as guidance information, a message "personal injury accident has occurred" and a route map in which the station in which the personal injury accident has occurred is highlighted, according to the guidance information generating rule. Note that the information on the route map is included in the operation information. For example, the station management system may have a route map, and the presentation information generating unit 13 may acquire information on the route map from the station management system. Also, for example, the storage unit may store the route map in advance, and the presentation information generating unit 13 may acquire information on the route map from the storage unit.

[0052] The display control unit 14 causes the display unit 31 to display the above-mentioned guidance information. FIG. 5 is a diagram showing an example of the display unit 31 in which the display control unit 14 in embodiment 1 displays guidance information including a message "Injury accident has occurred" and a route map highlighting the station where the injury accident has occurred. In Fig. 5, as an example, the route map shows a station where a fatal accident has occurred and three stations before and after the station where the fatal accident has occurred, lined up horizontally. The station where the fatal accident has occurred is highlighted by adding a speech bubble saying "Fatal Accident Occurred." The display format and highlighting method of the route map may be determined in advance, or may be set in the guide information generation rules or display conditions.

[0053] In this way, the presentation information generation unit 13 generates guidance information that uses diagrams to inform the user of the occurrence and content of the event to be notified about, so that the guidance control device 1 can provide the user with more visual guidance about the event to be notified about quickly and in a manner that allows the user to understand the content of the event. In the above example, the presentation information generation unit 13 generates guidance information that provides information about the occurrence and content of the event to be notified about using messages and illustrations. However, this is merely one example, and the presentation information generation unit 13 may generate guidance information that provides information about the occurrence and content of the event to be notified about using only illustrations.

[0054] <Variation (3)> In the first embodiment, the guidance control device 1 may combine the above-mentioned <Modification (1)> and <Modification (2)>. In other words, in the above-described embodiment 1, the presentation information generation unit 13 generates guidance information that uses a message or an illustration to inform users of the occurrence and details of the event to be notified about, and the display control unit 14 causes the display unit 31 to display this information, and the lighting control unit 15 may determine the train operation status based on the operation information and change the lighting cycle or lighting color of the lighting unit 32 according to the determined operation status. For example, when the display control unit 14 causes the display unit 31 to display guidance information as shown in FIG. 5, the lighting control unit 15 may, depending on the distance between the train and the station platform, slow down the lighting cycle of the lighting unit 32 when the distance between the train and the station platform is "far", and speed up the lighting cycle of the lighting unit 32 when the distance between the train and the station platform is "close" compared to when the distance between the train and the station platform is "far", and when the train arrives at the station, speed up the lighting cycle even further and cause the lighting unit 32 to flash.

[0055] <Variation (4)> In the above-described first embodiment, the lighting control unit 15 may change the lighting color of the lighting unit 32 depending on the type of event for which guidance is required that the determination unit 12 has determined that the event has occurred. For example, the lighting control unit 15 may light the lighting unit 32 in red if the event to be notified is an operational disruption, and may light the lighting unit 32 in white if the event is an arrival of a train.

[0056] In this way, by having the lighting control unit 15 change the lighting color of the lighting unit 32 depending on the type of event to be notified about, the guidance control device 1 can provide information about the event to be notified about in a way that allows the user to more intuitively understand the content of the event to be notified about.

[0057] <Variation (5)> In the above-described first embodiment, the guidance information is not limited to a message (characters) or a figure, and may be, for example, information utilizing light or animation. That is, in the above-described first embodiment, the presentation information generating unit 13 may generate guidance information that provides information on the occurrence and content of the event to be guided by using light or animation.

[0058] For example, the generation and display of guidance information in the form of animation will be described below with an example. In this case, the rules for generating guidance information correspond to, for example, the event to be guided and its contents, and a rule that animation is used as guidance information. For example, as a rule for generating guidance information when a fatal accident occurs, a rule that a service disruption and the contents of the service disruption, a fatal accident, a message saying "Fatal accident occurred", a route map highlighting the station where the fatal accident occurred, and an animation showing the same contents as the station announcement in a speech bubble form are used as guidance information. Note that "the same contents as the station announcement" here means "substantially the same contents as the station announcement", and does not mean the contents that are actually announced by voice in the station, but means that the gist of the contents is the same as the contents that are assumed to be announced by voice in the station.

[0059] The presentation information generating unit 13 generates, as the guidance information, a message saying "Injury accident has occurred", a route map highlighting the station where the injury accident has occurred, and an animation showing the same content as the in-station announcement in the form of a speech bubble, based on information acquired from the station management system, for example. As described above, the station management system manages information to be shared by station staff at each station, and outputs notification information addressed to station staff. The notification information addressed to station staff includes the content to be announced in the station and an instruction to each station staff to execute the announcement. The presentation information generating unit 13 may, for example, acquire notification information addressed to station staff from the station management system and specify the content to be announced in the station by voice. For example, it is assumed that information to be announced that a injury accident has occurred is output from the station management system as notification information addressed to station staff. In this case, the presentation information generating unit 13 presumes that an announcement should have been made in the station to inform users that a fatal accident has occurred. The presentation information generating unit 13 then generates, as guidance information, an animation in which the same content as the in-station announcement that a fatal accident has occurred is displayed in a speech bubble format. The type of animation in which the same content as the in-station announcement that a fatal accident has occurred is displayed in a speech bubble format is determined in advance. In the station, a station staff member makes an announcement, for example, "Currently, a fatal accident has occurred at △□ station. Due to this, the 〇〇 line is currently out of service. In addition, a transfer service is being provided on the △△ line." Based on an instruction from the station management system, the station staff member may make the announcement, for example, according to a template. Here, it is assumed that the station staff member actually speaks to make the announcement, but the station staff member may play a prepared voice in the station.

[0060] When the presentation information generation unit 13 generates guidance information including a message "Injury accident has occurred," a route map highlighting the station where the injury accident occurred, and an animation showing the same content as the in-station announcement in speech bubble format, the display control unit 14 causes the guidance information to be displayed on the display unit 31.

[0061] In addition, an example of generating and displaying guidance information when the guidance information is light will be described. In this case, in the guidance information generating rule, for example, a rule that the guidance target event and its contents are associated with light as the guidance information. For example, as a rule for generating guidance information when a personal injury accident occurs, a rule that a service interruption and a personal injury accident as the contents of the service interruption are associated with a message "personal injury accident occurred", and a station where the personal injury accident occurred is highlighted and an illuminated route map is used as the guidance information. The presentation information generating unit 13 generates, according to the guidance information generating rule, a message "personal injury accident occurred" and a route map where the station where the personal injury accident occurred is highlighted and illuminated as the guidance information. The display control unit 14 causes the display unit 31 to display the above-mentioned guidance information.

[0062] FIG. 6 is a diagram showing an example of a display unit 31 in which the presentation information generation unit 13 generates guidance information using messages, illustrations, light, and animation, and the display control unit 14 displays the guidance information in embodiment 1. Figure 6 shows an example of a display unit 31 that displays the message "Personal injury accident has occurred," a route map with the station where the accident has occurred highlighted and illuminated, and guidance information in the form of an animation in the form of a speech bubble that is the same content as the in-station announcement that a personal injury accident has occurred. In FIG. 6, as an example, the route map shows a station where a fatal accident has occurred and three stations before and after the station where the fatal accident has occurred, lined up side by side. The station where the fatal accident has occurred is highlighted by adding a speech bubble saying "Fatal Accident Occurred". The station where the fatal accident has occurred, together with the stations before and after it, is displayed in a bright light by increasing the brightness around the display area of ​​the station name or by using a bright color. An animation in the form of a speech bubble is displayed saying "Currently, due to a fatal accident, the XX line is not operating at the moment." This animation is an animation that shows the same content as an in-station announcement that a fatal accident is occurring in the form of a speech bubble. In FIG. 6, for convenience, it is shown as "XX line", but the display control unit 14 displays the line that passes through the station where the fatal accident has occurred as "XX line". The display format of the route map, the highlighting method, and the display format of the animation may be determined in advance, or may be set in the rules for generating guidance information or the display conditions.

[0063] In this way, the presentation information generation unit 13 generates guidance information that uses light or animation to inform the user of the occurrence and content of the event to be notified about, so that the guidance control device 1 can provide the user with more visual information about the event to be notified about quickly and in a manner that allows the user to understand the content of the event. Furthermore, the guidance control device 1 can provide the user with more detailed information about the content of the event to be notified. Furthermore, in the guidance control device 1, the presentation information generating unit 13 can generate, as guidance information, an animation showing the same content as the content related to the guidance target event that is presumed to have been announced by voice and that is determined to have occurred by the determining unit 12. This enables the guidance control device 1 to provide guidance to a hearing impaired person about the content that is presumed to have been announced by voice.

[0064] In addition to the above examples, the presentation information generating unit 13 can generate various kinds of guidance information that provides guidance on the occurrence and details of a notification target event using light or animation. For example, the presentation information generating unit 13 may generate, as the guide information, a route map in which the name of a station where an operation disruption is occurring is made bold, changed in color, changed in font size, changed in font style, etc. As a result, the display control unit 14 displays on the display unit 31 a route map in which the name of a station where an operation disruption is occurring is shown in bold, in a different color than other station names, in a different font size than other station names, or in a different font than other station names. Furthermore, for example, the presentation information generating unit 13 may generate, as the guide information, a route map that displays the current positions of trains in animation. Also, for example, the presentation information generating unit 13 may generate, as the guide information, an animation showing the number of cars of the next train arriving at the station platform, the stop position, the congestion state, or the train separation position. Note that the operation information includes information showing the congestion state of the train. For example, the presentation information generating unit 13 may generate guidance information that indicates the timing when the train doors will close by using light, a diagram, or an animation. Note that the information indicating the timing when the train doors will close is included in the operation information. Furthermore, for example, the presentation information generating unit 13 may generate, as the guide information, a time indicating an expected future recovery from the operational disruption, or a light or animation indicating that the operational disruption has been recovered from. For example, the presentation information generation unit 13 may generate guidance information that displays text indicating the stage of the response to an operational disruption (for example, occurrence of operational disruption → response in progress → expected recovery and alternative transportation → recovery) and highlights the current stage with light or animation. In addition, for example, while responding to an operational disruption, the presentation information generation unit 13 may generate, as guidance information, an animation showing a changing timetable (e.g., a timetable reflecting a delay time or an expected recovery time) when recovery from the operational disruption is performed. Also, for example, the presentation information generating unit 13 may generate, as guide information, a premises map in which facility devices that are unavailable due to reasons such as undergoing inspection are displayed in an animated form on the premises map. Furthermore, for example, the presentation information generating unit 13 may generate, as guide information, a station map or a timetable in which transfer information to secondary transportation (for example, destination, platform, departure time, etc.) is displayed in animation.

[0065] <Variation (6)> In the above-described first embodiment, the guidance control device may visualize the spoken content (for example, an in-station announcement) related to the event to be guided, generate information for displaying the spoken content (hereinafter referred to as "announcement presentation information") as guidance information, and display it on the display unit 31. In this case, the guidance control device has a configuration including a function of acquiring in-station voice, performing voice recognition, and visualizing the in-station announcement, in addition to the configuration of the guidance control device 1 as shown in Fig. 1, for example. FIG. 7 is a diagram showing an example of the configuration of a guidance control device 1a having a function of acquiring voices within a station, performing voice recognition, and visualizing station announcements in the first embodiment. 7, the same components as those in the guidance control device 1 described with reference to FIG. 1 are denoted by the same reference numerals, and duplicated description will be omitted. The guidance control device 1a shown in FIG. 7 differs from the guidance control device 1 shown in FIG. The guidance control device 1a and the information output device 3 constitute a guidance control system 100a.

[0066] The voice information acquiring unit 16 acquires voice information. In the first embodiment, the voice information acquired by the voice information acquiring unit 16 is, for example, a speech of a station staff member announced within the station premises. For example, the voice information acquisition unit 16 acquires a spoken voice from a voice input device (not shown). For example, a station staff member makes an in-station announcement regarding the event to be notified, such as "Currently, a fatal accident has occurred at △□ station. As a result, service on the 〇〇 line is currently suspended" to the voice input device. The voice input device accepts the spoken voice uttered by the station staff member as in the above example. The voice information acquisition unit 16 acquires the spoken voice of the station staff member accepted by the voice input device. The voice input device is, for example, a microphone, and is installed at the train boarding and alighting area or within the station premises. For example, the voice information acquisition unit 16 may acquire voice information when the determination unit 12 determines that a guidance target event has occurred. In this case, the determination unit 12 outputs event occurrence information to the voice information acquisition unit 16. In FIG. 7, an arrow from the determination unit 12 to the voice information acquisition unit 16 is omitted. For example, the voice information acquisition unit 16 may acquire voice information when it acquires notification information addressed to a station staff member who will make an announcement regarding the guidance target event from the station management system. In this case, the station management system outputs the notification information addressed to the station staff member to the voice information acquisition unit 16. This allows the voice information acquisition unit 16 to more reliably acquire the announced speech when a voice announcement regarding the guidance target event is being made, and prevents unnecessary speech from being acquired. The voice information acquisition unit 16 outputs the acquired voice information to the voice recognition unit 17 .

[0067] The voice recognition unit 17 recognizes the contents of the speech based on the voice information acquired by the voice information acquisition unit 16 . The voice recognition unit 17 may recognize the contents of the speech using a known voice recognition technology. For example, the voice recognition unit 17 may compare the voice information with a voice recognition dictionary database (not shown) to recognize the contents of the speech. The voice recognition dictionary database is a database that stores a voice recognition dictionary for performing voice recognition, and is provided in a location that the voice recognition unit 17 can refer to. For example, the voice recognition unit 17 may recognize the contents of the speech using artificial intelligence technology. The speech recognition unit 17 may recognize the contents of an utterance based on voice information, and the method of recognizing the contents of an utterance is not important. The voice recognition unit 17 outputs the speech content, more specifically, the recognition result of the announcement, to the presentation information generation unit 13.

[0068] When the judgment unit 12 judges that an event to be notified has occurred, in other words, when the judgment unit 12 outputs event occurrence information, the presentation information generation unit 13 generates, as guidance information, information for displaying the content of the voice utterance regarding the event to be notified, recognized by the voice recognition unit 17 based on the voice information, i.e., the content of the announcement (hereinafter referred to as "announcement presentation information"). The presentation information generating unit 13 assigns a display category, such as "1 (operational disruption) 3 (announcement)" or "2 (entering station) 3 (announcement)" to the generated guidance information.

[0069] The display control unit 14 causes the display unit 31 to display the announcement presentation information generated by the presentation information generating unit 13 as guidance information. The position, size, and display format on the display unit 31 on which the display control unit 14 displays the announcement presentation information may be determined in advance, or may be set by rules for generating guidance information or display conditions. For example, the display control unit 14 displays the announcement presentation information in a balloon-shaped animation. For example, the display control unit 14 may display the announcement presentation information on the display unit 31 in a balloon-shaped animation in which the outer periphery of the balloon blinks.

[0070] FIG. 8 is a diagram showing an example of the display unit 31 on which the display control unit 14 displays the announcement presentation information generated as guidance information in the first embodiment. In addition, in the above-mentioned Figure 5 etc., when showing an example of the display unit 31, the information output device 3, the lighting unit 32 and the main body unit 33 are also shown, but in Figure 8, for convenience, only the display unit 31 is shown. Figure 8 shows an example of guidance information displayed on the display unit 31 when a station staff member speaks into the voice input device, "There has currently been a fatal accident at △□ station. As a result, service on the XX line is currently suspended." In addition, in Fig. 8, an example of the blinking of the outer periphery of a speech bubble displaying guidance information is shown by arranging five speech bubbles in chronological order on the display unit 31. In Fig. 8, the second and fourth speech bubbles from the left are displayed with the outer periphery illuminated.

[0071] As described above, in the guidance control device 1a, the voice information acquisition unit 16 acquires the spoken voice as voice information, and the voice recognition unit 17 recognizes the spoken content based on the voice information acquired by the voice information acquisition unit 16. The presentation information generation unit 13 generates announcement presentation information for displaying the spoken content recognized by the voice recognition unit 17 as guidance information. The display control unit 14 displays, in a balloon format, the announcement presentation information generated as the guidance information by the presentation information generation unit 13. The display control unit 14 may display, in a balloon format, the announcement presentation information generated as the guidance information by the presentation information generation unit 13, as an animation in which the outer periphery of the balloon blinks. In this way, the guidance control device 1a can provide guidance to the user about the event to be notified so that the user can visually grasp the content of the currently announced speech and understand the content of the event to be notified. Also, the guidance control device 1a can provide guidance so that the user can understand that the guidance information is the currently announced speech content by displaying, for example, a speech bubble animation or an animation in which the outer periphery of the speech bubble blinks. In particular, people with hearing impairments cannot hear the audio being announced. The guidance control device 1a visualizes the audio spoken content about the event to be guided and displays the spoken content as guidance information on the display unit 31, thereby making it possible to visually guide people with hearing impairments about the spoken content about the event to be guided.

[0072] In the above description, the guidance control device 1a displays the contents of the utterance made by the station staff to the voice input device as guidance information on the display unit 31 as is. That is, in the guidance control device 1a, the presentation information generating unit 13 generates, as guidance information, announcement presentation information for displaying the contents of the announcement recognized by the voice recognition unit 17 based on the voice information as is. However, this is merely one example. For example, the presentation information generating unit 13 may generate, as the guidance information, announcement presentation information for displaying content from which words such as "umm," "ah," and so on, inserted between utterances (so-called fillers) have been deleted from the content of an announcement recognized based on voice information by the voice recognition unit 17. The presentation information generating unit 13 may, for example, store in advance the above-mentioned words to be deleted as keywords to be deleted, and delete the words inserted between utterances by searching for the stored keywords to be deleted from the recognition result of the utterance content output from the voice recognition unit 17. For example, when performing voice recognition, the voice recognition unit 17 may delete words inserted between utterances.

[0073] In the above description, the guidance information displayed by the guidance control device 1a is the content of speech uttered by the station staff into the voice input device, but this is merely one example. For example, the station staff may make an announcement according to a template. In this case, the guidance control device 1a may generate announcement presentation information for displaying the contents of the template read by the station staff as guidance information, instead of the contents of the speech recognized from the speech of the station staff, and may cause the display unit 31 to display the guidance information. In this case, in the guidance control device 1a, the voice information acquisition unit 16 acquires, as voice information, information on the template to be read by the station staff. For example, when the station management system outputs notification information addressed to a station staff member to be announced, the station management system also outputs the notification information addressed to the station staff member to the guidance control device 1a. At that time, the station management system also outputs information on the template to be read by the station staff member. Note that this is only one example, and for example, template candidates to be read by the station staff member are stored in advance in the storage unit, and when the notification information addressed to the station staff member is output from the station management system, the voice information acquisition unit 16 may refer to the storage unit to identify and acquire information on the template to be read by the station staff member from among the template candidates. For example, the notification information addressed to the station staff member output from the station management system to the guidance control device 1a is provided with information that can identify the template that has been instructed to be announced to the station staff member. Based on the information provided to the notification information addressed to the station staff member, the voice information acquisition unit 16 can identify the template to be read by the station staff member from among the templates stored in the storage unit. Also, for example, the voice information acquisition unit 16 may acquire from the voice recognition unit 17 the recognition result of the speech content that the voice recognition unit 17 recognizes in response to the speech spoken by the station staff into the voice input device, and identify the template that was read by the station staff by comparing the speech recognition result with the template candidates stored in the memory unit. In addition, when the voice information acquisition unit 16 acquires information of a template to be read by a station staff as voice information without using the recognition result of the speech content, the guidance control device 1a can be configured not to include the voice recognition unit 17. The presentation information generation unit 13 recognizes the content of the template as a voice utterance related to the event to be notified based on the voice information acquired by the voice information acquisition unit 16, and generates announcement presentation information for displaying the recognized content of the template as guidance information. The display control unit 14 displays this on the display unit 31.

[0074] Even in this manner, the guidance control device 1a can provide guidance on the event to be notified so that the user can visually grasp the content of the speech currently being announced and understand the content of the event to be notified. In addition, the guidance control device 1a visualizes the spoken content about the event to be guided by voice and displays the spoken content on the display unit 31 as guidance information, thereby enabling the hearing impaired person to visually guide the spoken content about the event to be guided by voice.

[0075] <Variation (7)> In the above <Variant Example (6)>, when the display control unit 14 causes the display unit 31 to display announcement presentation information as guidance information in the form of an animation, the display control unit 14 may display the guidance information in a form that makes it clear that the content is something that was actually announced within the premises by changing the colors of multiple characters contained in a sentence in the animation in sequence over time, starting from the first character of the sentence. As a specific example, suppose that a station staff member speaks to the voice input device, "Right now, there has been a fatal accident at △□ station. As a result, service on the XX line is currently suspended." In this case, the presentation information generating unit 13 generates, as guidance information, announcement presentation information for displaying an animation saying, "Right now, there has been a fatal accident at △□ station. As a result, service on the XX line is currently suspended." Then, the display control unit 14 displays a sentence such as, "Currently, there has been a fatal accident at △□ station. As a result, service on the XX line is currently suspended," and then superimposes the same sentence in succession, starting from the beginning of the sentence, with the text in different colors. The speed and number of characters that change color at one time are determined in advance.

[0076] FIG. 9 is a diagram showing another example of the display unit 31 on which the display control unit 14 displays the announcement presentation information generated as guidance information in the first embodiment. For convenience, only the display unit 31 is shown in FIG. Figure 9 shows an example of guidance information displayed on the display unit 31 when a station staff member speaks into the voice input device, "There has currently been a fatal accident at △□ station. As a result, service on the XX line is currently suspended." 9 shows an example of how the display control unit 14 displays the spoken content as an animation, and then changes the color of the characters contained in the sentence in the animation in order to superimpose the characters, starting from the top, by arranging four animations in chronological order on the display unit 31. For the sake of convenience, in FIG. 9, the content of the announcement before being superimposed is shown in white characters, and the characters superimposed in a different color are shown in bold black.

[0077] In this way, when the determination unit 12 determines that an event to be notified has occurred, in other words, when event occurrence information is output from the determination unit 12, the presentation information generation unit 13 generates, as guidance information, announcement presentation information for displaying the voice utterance content regarding the event to be notified, recognized based on the voice information acquired by the voice information acquisition unit 16, and the display control unit 14 displays the announcement presentation information generated by the presentation information generation unit 13 as guidance information in the form of an animation, and may display on the display unit 31 the colors of multiple characters contained in a sentence in the animation, changing in sequence over time starting from the first character of the sentence. In this way, the guidance control device 1a can provide guidance to the user about the event to be notified so that the user can visually grasp the content of the currently announced speech and understand the content of the event to be notified. Also, the guidance control device 1a can provide guidance information so that the user can understand that it is the currently announced speech content. In particular, people with hearing impairments cannot hear the audio being announced. The guidance control device 1a visualizes the audio spoken content about the event to be guided and displays the spoken content as guidance information on the display unit 31, thereby enabling the hearing impaired to visually understand that the spoken content about the event to be guided is the currently announced content.

[0078] In the above example, the display control unit 14 displays the guidance information in a display form that changes the color of the text so that it is clear that the spoken content is related to the event to be notified, but this is merely one example. For example, the display control unit 14 may display the guidance information as an animation, and may display multiple characters contained in the sentence in the animation as the sentence, and then underline the characters in the sentence in order over time, starting from the first character.

[0079] <Variation (8)> In <Variant Example (6)> or <Variant Example (7)>, the guidance control device 1a may visualize the spoken content (e.g., an in-station announcement) regarding the event to be guided about, generate announcement presentation information for displaying the spoken content as guidance information, display it on the display unit 31, and change the lighting of the lighting unit 32. More specifically, in the guidance control device 1a, when the display control unit 14 causes the display unit 31 to display the announcement presentation information generated as guidance information, the lighting control unit 15 causes the lighting unit 32 to light up in a lighting pattern indicating that the displayed guidance information is speech content (hereinafter referred to as the "announcement notification lighting pattern"). Note that the announcement notification lighting pattern is, for example, predetermined.

[0080] FIG. 10 is a diagram showing an example of the appearance of the information output device 3 in which, in embodiment 1, the display control unit 14 causes the display unit 31 to display guidance information for displaying the content of the utterance, and the lighting control unit 15 causes the lighting unit 32 to light up in an announcement notification lighting pattern. In FIG. 10, as an example, it is assumed that a station staff member speaks into a voice input device, "Currently, trains are being delayed due to strong winds." 10, as an example, the display control unit 14 displays the guidance information in the form of an animation in which the outer periphery of a speech bubble displaying "Trains are currently delayed due to strong winds" blinks. The lighting control unit 15 lights up the lighting unit 32 so that the lighting color changes over time from the end to the center of the lighting unit 32. Here, the announcement notification lighting pattern is set to light up the lighting unit 32 so that the lighting color changes over time from the end to the center of the lighting unit 32.

[0081] The announcement notification lighting pattern may be different depending on the type of the event to be notified. For example, the announcement notification lighting pattern according to the type of the event to be notified is set in the guidance information generating rule or the display condition, and the display control unit 14 may determine the announcement notification lighting pattern based on the guidance information generating rule or by matching the display classification in the display condition with the event to be notified specified from the event occurrence information or the operation information.

[0082] In this way, when the display control unit 14 causes the display unit 31 to display the announcement presentation information generated as guidance information, the lighting control unit 15 may cause the lighting unit 32 to light up in a lighting pattern (announcement notification lighting pattern) indicating that the displayed guidance information is the content of the speech. In this way, the guidance control device 1a can provide guidance to the user about the event to be guided, allowing the user to visually and intuitively understand the content of the currently announced speech. Also, the guidance control device 1a can provide guidance information in a way that makes it clear that the currently announced speech content is the guidance information. In particular, people with hearing impairments cannot hear the audio being announced. The guidance control device 1a visualizes the audio spoken content about the event to be guided and displays the spoken content as guidance information on the display unit 31, thereby enabling the hearing impaired to visually understand that the spoken content about the event to be guided is the currently announced content.

[0083] In the first embodiment, the operation of the guidance control device 1a in the case where the guidance control device is a guidance control device 1a having the configuration as shown in FIG. 7, that is, in the above-mentioned <Modification (6)> to <Modification (8)> will be described. FIG. 11 is a flowchart for explaining the operation of the guidance control device 1a in the first embodiment when the guidance control device is the guidance control device 1a having the configuration as shown in FIG. For example, when the power supply to the guidance control device 1a is turned on or when an instruction to start the operation is received from an administrator or the like, the guidance control device 1a starts the operation as shown in the flowchart of Fig. 11. For example, the guidance control device 1a repeats the operation as shown in the flowchart of Fig. 11 until the power supply to the guidance control device 1a is turned off or an instruction to end the operation is received from an administrator or the like. A manager or the like inputs an operation start instruction or an operation end instruction from a PC installed in, for example, a station control room. A control unit (not shown) of the guidance control device 1a receives the operation start instruction and starts the operations of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, the voice information acquisition unit 16, and the voice recognition unit 17. The control unit also receives an operation end instruction and ends the operations of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, the voice information acquisition unit 16, and the voice recognition unit 17.

[0084] The details of the processes in steps ST10 and ST20 in FIG. 11 are similar to the details of the processes in steps ST10 and ST20 in FIG. 4 that have already been described, and therefore will not be described again.

[0085] The voice information acquiring unit 16 acquires voice information (step ST21). The voice information acquisition unit 16 outputs the acquired voice information to the voice recognition unit 17 .

[0086] The voice recognition unit 17 recognizes the contents of the utterance based on the voice information acquired by the voice information acquisition unit 16 in step ST21 (step ST22). The voice recognition unit 17 outputs the speech content, more specifically, the recognition result of the announcement, to the presentation information generation unit 13.

[0087] When the judgment unit 12 judges in step ST20 that an event to be notified has occurred (in the case of "YES" in step ST20), in other words, when event occurrence information is output from the judgment unit 12, the presentation information generation unit 13 generates, as guidance information (step ST30a), the announcement presentation information for displaying the content of the voice utterance regarding the event to be notified, i.e., the content of the announcement, which is recognized by the voice recognition unit 17 based on the voice information in step ST22 (step ST30a).

[0088] The display control unit 14 causes the display unit 31 to display the announcement presentation information generated as the guidance information by the presentation information generating unit 13 in step ST30a (step ST40a).

[0089] When the display control unit 14 causes the display unit 31 to display the guidance information in step ST40a, the lighting control unit 15 turns on the lighting unit 32. At this time, the lighting control unit 15 turns on the lighting unit 32 in an announcement notification lighting pattern (step ST50a).

[0090] 11, the processes of steps ST21 to ST22 are performed after step ST20, but this is merely an example. For example, the processes of steps ST10 to ST20 and the processes of steps ST21 to ST22 may be performed in parallel.

[0091] In addition, for example, if the lighting control unit 15 does not have the function of lighting the lighting unit 32 in the announcement notification lighting pattern (for example, in the case of <Variant Example (6)> or <Variant Example (7)>), the lighting control unit 15 may, in step ST50a, light the lighting unit 32 in, for example, a predetermined lighting pattern.

[0092] Also, for example, in the case where the presentation information generation unit 13 generates, in step ST30a, announcement presentation information for displaying the contents of a template to be read by a station attendant as guidance information, and the recognition results of the speech content are not used in generating the guidance information, the guidance control device 1a can omit the processing of step ST22.

[0093] <Variation (9)> In the above-described embodiment 1, the guidance control device 1, in addition to the function of controlling the display of guidance information on the display unit 31 and controlling the lighting of the lighting unit 32, may also have, for example, a function of controlling the execution of inquiries to station staff, etc., a display control function of a station interior map, a display control function of information about the area around the station, a display control function of secondary traffic information, a display control function of a route map, a display control function of a timetable, a multilingual display function, or a translation function.

[0094] Regarding the function of controlling the execution of inquiries to station staff, for example, in the guidance control device 1, the display control unit 14 displays an inquiry button at a preset position on the display unit 31. The shape of the inquiry button is not important. Note that here, the display unit 31 is assumed to be a touch panel type liquid crystal display. When a user operates the inquiry button, the control unit of the guidance control device 1 accepts this and notifies a PC or the like provided in the management room that an inquiry has been made, enabling a call between the PC or the like and the information output device 3. The information output device 3 is equipped with a speaker (not shown) and a microphone (not shown), and the speaker outputs the voice of the station staff. In addition, the microphone collects the voice of the user, etc. For example, in the guidance control device 1, the control unit may accept an inquiry from a user in a chat format. When the control unit accepts an operation of a user's inquiry button or the like, the control unit causes the display unit 31 to display an automatic response message via the display control unit 14. The control unit may respond to the inquiry from the user in chat format using a known technique for dialogue in chat format. By being able to respond to inquiries from users in chat format, the guidance control device 1 can respond to inquiries even if the user is hearing impaired.

[0095] Regarding the display control function of station maps, secondary traffic information, route maps, or timetables, in the guidance control device 1, the display control unit 14 may, for example, acquire this information from the operation system 2 and display it at a preset position on the display unit 31.

[0096] Regarding the display control function of the station surrounding information, for example, in the guidance control device 1, the display control unit 14 may acquire the station surrounding information from, for example, a station management system and display it at a preset position on the display unit 31. The station management system holds the station surrounding information.

[0097] Regarding the multilingual display function or translation function, for example, in the guidance control device 1, the display control unit 14 may perform multilingual display or translation results display using a known multilingual display technique or a known translation technique.

[0098] In the above-described first embodiment, the above-described <Modification (1)> to <Modification (9)> may be applied in combination.

[0099] 12A and 12B are diagrams illustrating an example of a hardware configuration of the guidance control device 1 according to the first embodiment. In the first embodiment, the functions of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, and a control unit (not shown) are realized by the processing circuit 1001. That is, the guidance control device 1 includes the processing circuit 1001 for determining whether or not a guidance target event has occurred based on the acquired operation information, and for generating guidance information and displaying it on the display unit 31 and for controlling the lighting unit 32 to be turned on when it is determined that a guidance target event has occurred. The processing circuit 1001 may be dedicated hardware as shown in FIG. 12A, or may be a processor 1004 that executes a program stored in a memory as shown in FIG. 12B.

[0100] When the processing circuit 1001 is dedicated hardware, the processing circuit 1001 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof.

[0101] When the processing circuit is the processor 1004, the functions of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, and a control unit (not shown) are realized by software, firmware, or a combination of software and firmware.

Here, the memory 1005 corresponds to, for example, a non-volatile or volatile semiconductor memory such as a RAM, a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable Read Only Memory), or an EEPROM (Electrically Erasable Programmable Read-Only Memory), or a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD (Digital Versatile Disc), or the like.

[0102] The functions of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, and a control unit (not shown) may be partially realized by dedicated hardware and partially realized by software or firmware. For example, the operation information acquisition unit 11 may be realized by a processing circuit 1001 as dedicated hardware, and the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, and a control unit (not shown) may be realized by a processor 1004 reading out and executing a program stored in a memory 1005. The storage unit (not shown) is composed of, for example, a memory 1005, an HDD, or an SSD. The guidance control device 1 also includes an input interface device 1002 and an output interface device 1003 that perform wired or wireless communication with devices such as the operation system 2 or the information output device 3.

[0103] When the guidance control device is the guidance control device 1a as shown in FIG. 7, the hardware configuration of the guidance control device 1a is also the configuration shown in FIG. 12A and FIG. 12B. In the guidance control device 1a, the functions of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, the voice information acquisition unit 16, the voice recognition unit 17, and a control unit (not shown) are realized by a processing circuit 1001. That is, the guidance control device 1a includes the processing circuit 1001 for controlling visualization of the contents of the on-site announcements based on the voice information. The processing circuit 1001 may be dedicated hardware as shown in FIG. 12A, or may be a processor 1004 that executes a program stored in a memory as shown in FIG. 12B.

[0104] The processing circuit 1001 reads out and executes the programs stored in the memory 1005, thereby executing the functions of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, the voice information acquisition unit 16, the voice recognition unit 17, and a control unit (not shown). That is, the guidance control device 1a includes a memory 1005 for storing a program that, when executed by the processing circuit 1001, results in the execution of steps ST10 to ST50a in FIG. 11 described above. It can also be said that the program stored in the memory 1005 causes a computer to execute the procedures or methods of the processing of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, the voice information acquisition unit 16, the voice recognition unit 17, and a control unit (not shown). The storage unit (not shown) is composed of, for example, a memory 1005, an HDD, or an SSD. The guidance control device 1a also includes an input interface device 1002 and an output interface device 1003 that perform wired or wireless communication with devices such as the operation system 2 or the information output device 3.

[0105] In the above first embodiment, an operational disruption has been given as an example of a sudden event for which information is to be provided, and an arrival of a train has been given as an example of an event for which users should be prepared in advance, but this is merely one example. The unexpected events include troubles at the boarding / alighting area, such as trespassing on the tracks or nuisances, as well as operational disruptions. The guidance control device 1, 1a may acquire trespassing on the tracks as operation information from, for example, a station management system. For example, when an emergency bell is rung at a boarding / alighting area of ​​a station, the station management system detects that a trouble has occurred at the boarding / alighting area and outputs operation information indicating that a trouble has occurred at the boarding / alighting area to the guidance control device 1, 1a. Events that users should prepare for in advance include, for example, the delivery of large cargo, in addition to trains arriving at the station. The guidance control device 1, 1a may obtain the delivery of large cargo as operation information, for example, from a station management system. For example, the station management system accepts the delivery of large cargo from a contractor. The contractor notifies the station management system of the delivery of large cargo via the mobile terminal, for example, by inputting the delivery of large cargo from a mobile terminal. At this time, the contractor also notifies the station management system of the delivery of large cargo, for example, of information such as elevators and boarding and disembarking areas to be used to deliver the large cargo. When the station management system accepts the delivery of large cargo, it outputs the delivery route of the large cargo, etc., to the guidance control device 1, 1a as operation information.

[0106] In the above-described first embodiment, the information output device 3 is provided at a platform of a station where trains can arrive and depart, but this is merely an example. The information output device 3 may be provided at a location other than the platform of a station, such as a ticket gate of a station. The guidance control device 1, 1a can also perform display control of the display unit 31 and lighting control of the lighting unit 32 provided in the information output device 3 provided at a location other than the platform of a station.

[0107] In the above first embodiment, the guidance control device 1, 1a is mounted on, for example, a server, but this is merely one example. For example, the guidance control device 1, 1a may be provided in a place other than the server, such as the information output device 3 or a PC provided in a management room, etc. Also, for example, some of the operation information acquisition unit 11, the determination unit 12, the presentation information generation unit 13, the display control unit 14, the lighting control unit 15, the voice information acquisition unit 16, the voice recognition unit 17, or a control unit not shown in the figure may be mounted on the server, and the rest may be provided in a place other than the server, and a system may be configured with the server and a place other than the server.

[0108] In addition, in the above embodiment 1, as an example, the moving body is a train, and the guidance control device 1, 1a performs display control of the display unit 31 and lighting control of the lighting unit 32 provided on the information output device 3 provided at the boarding and alighting platforms of stations where the train can depart and arrive, but this is merely one example. The guidance control device 1, 1a can provide guidance regarding any mobile object to a user who uses the mobile object, for example, by controlling the display of the display unit 31 that displays information about the mobile object and the lighting of the lighting unit 32. For example, the guidance control device 1, 1a can generate guidance information that provides information about the occurrence and details of events to be notified at boarding and disembarking points where vehicles such as buses or taxis, aircraft, ships such as ferries, or rides at entertainment facilities such as amusement parks (hereinafter referred to as "various mobile bodies") can depart and arrive, and can control the display and lighting of the guidance information. In this case, the operation system 2 is a system owned by, for example, a bus management company, a taxi management company, an airline company, a shipping company, or an entertainment facility management company, and manages the operation of various mobile bodies.

[0109] As described above, according to the first embodiment, the guidance control device 1, 1a is configured to include an operation information acquisition unit 11 that acquires operation information related to the operation of a mobile object, a determination unit 12 that determines whether or not an event to be notified has occurred based on the operation information acquired by the operation information acquisition unit 11, a presentation information generation unit 13 that generates guidance information to provide information about the occurrence and details of the event to be notified when the determination unit 12 determines that an event to be notified has occurred, a display control unit 14 that causes the display unit 31 to display the guidance information generated by the presentation information generation unit 13, and a lighting control unit 15 that turns on the lighting unit 32 when the display control unit 14 causes the display unit 31 to display the guidance information. Therefore, the guidance control device 1, 1a can provide guidance to a user about an event promptly and in a manner that allows the user to understand the details of the event.

[0110] Any of the components of the embodiments may be modified or omitted. [Industrial Applicability]
