DETAILED DESCRIPTION OF THE INVENTION

[0011] [Embodiment 1] An embodiment of the present invention will be described in detail below. Fig. 1 is a block diagram showing the configuration of an elevator system 100 including a destination floor registration device 1 according to the first embodiment of the present invention. As shown in Fig. 1, the elevator system 100 includes the destination floor registration device 1, a group management control device 2, an elevator control device 3, and an elevator 4.

[0012] The destination floor registration device 1 registers a destination floor call based on the operation of a user using the elevator 4, and presents the allocation result by the group management control device 2. The destination floor registration device 1 also has an output unit 14 capable of outputting sound, and outputs sound indicating various information related to the call registration from the output unit 14. Furthermore, the destination floor registration device 1 measures the distance between the user's face and the output unit 14, and controls the volume of the sound output from the output unit 14 according to the measured distance. Hereinafter, the distance between the user's face and the output unit 14 is also referred to as the "user distance." Details of the destination floor registration device 1 will be described later.

[0013] The group management control device 2 assigns an elevator 4 to the destination floor call received from the destination floor registration device 1. The group management control device 2 also transmits assignment result information to the destination floor registration device 1, which is the source of the destination floor call. The assignment result information includes information indicating the elevator number assigned to the destination floor call. The group management control device 2 also transmits information instructing the elevator 4 to operate based on the registered destination floor call to the elevator control device 3, which controls the elevator 4 number assigned to the destination floor call.

[0014] The elevator control device 3 controls the movement of the elevator 4 between floors and the opening and closing of the doors based on instructions from the group control device 2. The elevator 4 is installed in a building and operates based on the control of the elevator control device 3. One or more elevators 4 may be installed in one building. The following describes an example of a configuration in which multiple elevators 4 are installed in one building and the group control device 2 assigns the optimal elevator number to each destination floor call.

[0015] <Destination Floor Registration Device 1> 2 is a schematic diagram showing an example of a destination floor registration device 1. The destination floor registration device 1 is a device used by users of elevators 4 to register destination floor calls. The destination floor registration device 1 transmits destination floor calls based on input operations by the users to the group management control device 2, and presents allocation results based on the destination floor calls.

[0016] The destination floor registration device 1 is installed, for example, at the landing of the elevator 4. The number of destination floor registration devices 1 provided in the elevator system 100 may be one or more. As an example, the destination floor registration device 1 may be installed at the landing of each floor of a building. Also, multiple destination floor registration devices 1 may be installed at the landing of one floor.

[0017] The destination floor registration device 1 can display a predetermined screen and register a destination floor call based on a user's input operation in response to the content of the displayed screen. The destination floor registration device 1 can also output a predetermined sound and register a destination floor call based on a user's input operation in response to the content of the output sound. Hereinafter, call registration based on the screen display will be referred to as first call registration. Also, destination floor call registration based on voice guidance will be referred to as second call registration.

[0018] When processing the second call registration, the destination floor registration device 1 notifies the user of floors that can be designated as destination floors by voice guidance. By performing an operation to designate one of the notified floors, the user can register a destination floor call with that floor as the destination floor. For example, if a user has difficulty performing the first call registration, such as a visually impaired user, the user can register a destination floor call without relying on vision by performing the second call registration.

[0019] As shown in FIGS. 1 and 2, the destination floor registration device 1 includes a display unit 13, an output unit 14, a first operation acceptance unit 15, a second operation acceptance unit 16, a sensor 17, a memory unit 12, and a control unit 11. The display unit 13 displays a screen based on the control of a display control unit 113 (described later). The display unit 13 may be, for example, a display capable of displaying a predetermined screen. The display may also have a function as a touch panel. The output unit 14 outputs sound based on the control of an output control unit 116 (described later). The output unit 14 may be, for example, a speaker.

[0020] The first operation acceptance unit 15 accepts an input operation related to the first call registration and outputs a signal corresponding to the accepted input operation to the control unit 11. The first operation acceptance unit 15 accepts an input operation to specify a destination floor. The operation to specify a destination floor may be an operation to specify one of the floors displayed on the display unit 13. The first operation acceptance unit 15 may be a button that can accept an input operation to specify a destination floor. Alternatively, the first operation acceptance unit 15 may be, for example, a touch panel. When the first operation acceptance unit 15 is a touch panel, the touch panel may have the functions of both the display unit 13 and the first operation acceptance unit 15.

[0021] The second operation acceptance unit 16 accepts an input operation related to the second call registration, and outputs a signal corresponding to the accepted input operation to the control unit 11. The second operation acceptance unit 16 may be a button that can accept an input operation by a user. The second operation acceptance unit 16 accepts an input operation that instructs the start of voice guidance. Specifically, the input operation may be an operation of pressing a button that is the second operation acceptance unit 16. When the second operation acceptance unit 16 accepts the input operation, the destination floor registration device 1 starts processing related to the second call registration. Hereinafter, the period during which processing related to the second call registration is being performed is also referred to as the "period during which voice guidance is being performed by the output unit 14."

[0022] Additionally, while voice guidance is being provided by the output unit 14, the second operation receiving unit 16 receives an input operation for specifying a destination floor. The input operation for specifying a destination floor may be an input operation for specifying a floor that has been announced by voice from the output unit 14. Specifically, the input operation may be an operation of pressing a button that is the second operation receiving unit 16.

[0023] The sensor 17 is a sensor that can output a signal according to the distance between the user's face and the output unit 14. The sensor 17 may be, for example, a TOF (Time-Of-Flight) distance measuring sensor.

[0024] The storage unit 12 stores various information used in the destination floor registration device 1. As shown in Fig. 1, the storage unit 12 stores distance information 121, reference volume information 122, volume control information 123, and floor information 124. The reference volume information 122 is information indicating a reference volume when providing voice guidance. The volume control information 123 is information indicating a changed volume determined based on the user distance.

[0025] 3 is a diagram showing an example of distance information 121 stored in storage unit 12. Distance information 121 includes information indicating a user distance corresponding to a user performing an operation related to second call registration. As shown in FIG. 3, storage unit 12 may store, as distance information 121, information indicating the user distance and information indicating the time at which the distance was measured, in association with each other. During the period in which processing related to second call registration is being performed, new distance information 121 is stored each time the user distance is measured.

[0026] Fig. 4 is a diagram showing an example of floor information 124 stored in storage unit 12. Floor information 124 is information indicating the floors of the building on which elevator 4 is installed. As shown in Fig. 4, floor information 124 stores floor names indicating the floors of the building and identification numbers (N) for identifying the floor names, in association with each floor.

[0027] The control unit 11 executes various controls performed by the destination floor registration device 1. As shown in FIG. 1 , the control unit 11 includes a reception unit 111, a registration unit 112, a display control unit 113, a measurement unit 114, a determination unit 115, and an output control unit 116.

[0028] (Reception Department 111) The reception unit 111 receives an input operation by a user. The reception unit 111 acquires a signal indicating the content of the input operation from the first operation reception unit 15 or the second operation reception unit 16, and identifies the input operation performed on the first operation reception unit 15 or the second operation reception unit 16. If the reception unit 111 is in a state where it can receive the identified input operation, the reception unit 111 receives the input operation and performs a predetermined process based on the content of the received input operation.

[0029] During the period when processing related to the second call registration is not being performed, the reception unit 111 can accept an operation to specify a destination floor performed on the first operation reception unit 15, or an operation to start the second call registration performed on the second operation reception unit 16.

[0030] When an operation to specify a destination floor is performed on the first operation reception unit 15, the reception unit 111 receives the operation. At this time, the reception unit 111 acquires information indicating the destination floor input by the user from the first operation reception unit 15. The reception unit 111 outputs the information indicating the destination floor acquired from the first operation reception unit 15 to the registration unit 112. As a result, the destination floor registration device 1 starts processing related to the first call registration. Hereinafter, the operation to specify a destination floor performed on the first operation reception unit 15 is also referred to as a "first specification operation."

[0031] Furthermore, during a period when processing related to the second call registration is not being performed, the reception unit 111 can receive an operation to instruct the start of voice guidance, which is performed on the second operation reception unit 16. Hereinafter, an operation to instruct the start of voice guidance, which is performed on the second operation reception unit 16, is also referred to as a "start operation."

[0032] When a start operation is performed on the second operation reception unit 16, the reception unit 111 receives the start operation. When the reception unit 111 receives a signal indicating that the start operation has been performed, it transmits a service floor acquisition request to the group management control device 2. The service floor acquisition request is information requesting the provision of service floor information indicating service floors at which the elevator 4 can stop. When the group management control device 2 receives the service floor acquisition request, it transmits the service floor information to the destination floor registration device 1. Note that the group management control device 2 excludes from the service floors the floor on which the destination floor registration device 1 that sent the service floor acquisition request is installed. When the reception unit 111 receives the service floor information, it stores the service floor information in the memory unit 12. Thereafter, the reception unit 111 decides to start second call registration and outputs information indicating the start of second call registration to each unit of the control unit 11. As a result, the destination floor registration device 1 starts processing related to the second call registration. Furthermore, after the process related to the second call registration has started, the reception unit 111 is in a state where it cannot receive a start operation until the process is completed. Note that, when the process related to the first call registration or the process related to the second call registration is completed, the reception unit 111 is in a state where it can receive a first designation operation and a start operation.

[0033] While the process for the second call registration is being performed, the output unit 14 issues a sound indicating each floor that can be specified as a destination floor. When the user is notified of their destination floor, they perform an input operation to the second operation receiving unit 16 to specify one of the notified floors as a destination floor.

[0034] The reception unit 111 can receive an input operation for specifying the notified first floor from the time when the output unit 14 notifies the first floor until the next floor is notified. Hereinafter, an input operation performed on the second operation reception unit 16 to specify the notified first floor as the destination floor will also be referred to as a "second specification operation." When the reception unit 111 receives the second specification operation, it outputs information indicating the floor specified by the second specification operation to the registration unit 112. This registers a destination floor call with the specified floor as the destination floor. The reception unit 111 also outputs information indicating that the second specification operation has been received to the output control unit 116.

[0035] (Registration Unit 112) The registration unit 112 registers a destination floor call based on an input operation by the user. When the reception unit 111 receives a first designation operation, the registration unit 112 registers the destination floor call. Specifically, the registration unit 112 generates a destination floor call in which the floor designated by the first designation operation is the destination floor and the floor on which the destination floor registration device 1 is installed is the departure floor, and transmits the generated destination floor call to the group management control device 2.

[0036] Furthermore, if the reception unit 111 receives a second designation operation during the period from when one floor is notified by the output unit 14 until when the next floor is notified, the registration unit 112 registers a destination floor call. Specifically, the registration unit 112 generates a destination floor call in which the floor designated by the second designation operation is the destination floor and the floor on which the destination floor registration device 1 is installed is the departure floor, and transmits the generated destination floor call to the group management control device 2.

[0037] According to the above configuration, if the reception unit 111 receives a predetermined operation between the notification of one floor and the notification of the next floor, the registration unit 112 registers a destination floor call with the one floor as the destination floor. For example, a user can register a destination floor call with the second floor as the destination floor by performing a predetermined operation after the output unit reports "second floor" and before the next floor, for example, "third floor," is reported. In this way, since a user can register a destination floor call simply by performing a predetermined operation, there is no need for the user to search for a button corresponding to the desired floor to make a destination floor call. Therefore, the above configuration can improve convenience for users.

[0038] (Display control unit 113) The display control unit 113 controls the screen display on the display unit 13. Specifically, while the reception unit 111 is not receiving an input operation from the user, the display control unit 113 displays a destination floor registration screen on the display unit 13. The destination floor registration screen is a screen that includes information indicating floors that can be designated as destination floors.

[0039] While the display control unit 113 is causing the display unit 13 to display the destination floor registration screen, the reception unit 111 can receive a first designation operation. When the reception unit 111 receives the first designation operation, a destination floor call with the selected floor as the destination floor is registered. When the group management control device 2 assigns an elevator 4 to the destination floor call, the display control unit 113 receives assignment result information from the group management control device 2. The assignment result information includes information indicating the elevator number assigned to the destination floor call.

[0040] When the display control unit 113 receives the allocation result information from the group management control device 2, it causes an allocation result screen to be displayed on the display unit 13. The allocation result screen is a screen that includes information indicating that the registration of the destination floor call has been completed and the elevator number that has been allocated to the destination floor call.

[0041] After displaying the allocation result screen for a predetermined time, the display control unit 113 decides to end the processing related to the first call registration, and outputs information indicating that the processing related to the first call registration is ended to each unit of the control unit 11. This ends the processing related to the first call registration in the destination floor registration device 1. When the processing related to the first call registration is ended, the display control unit 113 causes the display unit 13 to display a destination floor registration screen.

[0042] (Measurement section 114) The measurement unit 114 measures the distance between the user's face and the output unit 14 during the period when the output unit 14 is outputting audio. The measurement unit 114 acquires the signal output by the sensor 17 and measures the user distance based on the signal. The measurement unit 114 associates information indicating the measured distance with information indicating the time when the measurement was made, and stores the information as distance information 121 in the storage unit 12. Note that the period when the output unit 14 is outputting audio is not limited to the period when audio is actually being played from the output unit 14, but includes the period when audio can be played from the output unit 14, i.e., the entire period when processing related to one second call registration is being performed.

[0043] The measurement unit 114 may measure the user distance every time it receives a signal from the sensor 17, or may measure the user distance at predetermined time intervals. For example, the measurement unit 114 may measure the user distance every second. The time interval at which the measurement unit 114 performs measurements may be longer or shorter than one second.

[0044] The measurement unit 114 starts measuring the user distance when the destination floor registration device 1 starts processing related to the second call registration. Furthermore, when the processing related to the second call registration is completed, the measurement unit 114 ends measuring the user distance. At this time, the measurement unit 114 may delete the distance information 121 stored in the storage unit 12. As a result, after the processing related to the second call registration is completed, when the next second call registration is performed, the distance information 121 related to the user who performed the completed second call registration will be deleted. As a result, when determining a user who will perform a new second call registration, it is possible to reduce the possibility that the distance information 121 related to the user who performed the previous second call registration will be erroneously used.

[0045] (Judgment unit 115) The determination unit 115 determines a change in the user distance based on the measurement result of the measurement unit 114. When the determination unit 115 acquires information indicating that the distance information 121 has been updated from the measurement unit 114, the determination unit 115 makes a determination based on the distance information 121 in the storage unit 12. If the user distance has changed so that the user is approaching the output unit 14, in other words, if the user distance has changed to become smaller, the determination unit 115 determines that the user has approached the output unit 14. If the user distance has changed so that the user is moving away from the output unit 14, in other words, if the user distance has changed to become larger, the determination unit 115 determines that the user has moved away from the output unit 14. If the user distance has not changed, the determination unit 115 determines that the user distance has not changed.

[0046] Note that the determination unit 115 may determine that the user distance has not changed if the change in the user distance is less than a predetermined value (for example, 2 cm). While the user is performing an operation on the destination floor registration device 1, the user distance may change in accordance with the user's actions, even if the user does not desire a change in volume. According to the above configuration, if the change in the user distance is less than a predetermined value, the determination unit 115 determines that the user distance has not changed. For example, if the user's posture changes slightly following an operation on the destination floor registration device 1, and there is a change in the user distance to such an extent that it is considered that the user does not desire a change in volume, the determination unit 115 determines that the user distance has not changed. This reduces the possibility that volume adjustments that are unnecessary for the user are made.

[0047] Furthermore, the determination unit 115 determines a change in the user distance during a predetermined time period at predetermined intervals. The determination unit 115 determines a change in the user distance based on the distance information 121 at two points in time. The interval at which the determination unit 115 performs the determination may be, for example, one second. In this case, the determination unit 115 may determine a change in the user distance for one second every second.

[0048] For example, the determination unit 115 determines a change in the user distance over one second based on the latest distance information 121 and the distance information one second before the latest one 121. In this case, the determination unit 115 determines whether the user distance has decreased, increased, or remained unchanged between the reference time point and the time point when the latest distance information 121 was measured.

[0049] 3 is stored in the storage unit 12, the determination unit 115 acquires the latest distance information 121 (reference numeral 301) and the distance information 121 one second before the latest one (reference numeral 302). In this case, the user distance indicated in the latest distance information 121 (reference numeral 301) is greater than the user distance indicated in the distance information 121 one second before the latest one (reference numeral 302). In other words, the distance between the user's face and the output unit 14 has changed in the direction of increasing over the course of one second. Therefore, the determination unit 115 determines that the user has moved away from the output unit 14 based on the acquired distance information 121 at two points in time.

[0050] As another example, when the distance information 121 indicated by reference numeral 303 in FIG. 3 is stored in the storage unit 12 as the latest distance information 121, the determination unit 115 acquires the latest distance information 121 (reference numeral 303) and the distance information 121 one second before the latest one (reference numeral 304). In this case, the user distance indicated in the latest distance information 121 (reference numeral 303) is smaller than the user distance indicated in the distance information 121 one second before the latest one (reference numeral 304). In other words, the distance between the user's face and the output unit 14 changes in a direction toward getting closer over one second. Therefore, the determination unit 115 determines that the user has approached the output unit 14 based on the acquired distance information 121 at two points in time.

[0051] The interval at which the determination unit 115 makes the determination is not limited to one second, and may be longer or shorter than one second. The determination unit 115 may make the determination based on the latest distance information 121 and the distance information 121 one second before the latest, or may make the determination based on the latest distance information 121 and the distance information 121 at a different time point. For example, the determination unit 115 may use the time point at which the distance information 121 one second before the latest was measured as described above, or may use a time point even earlier. When the measurement unit 114 updates the distance information 121 at intervals shorter than one second, the determination unit 115 may use the time point at which the latest distance information 121 was measured as a reference time point closer to the time point at which the latest distance information 121 was measured than the time point at which the distance information 121 one second before the latest was measured.

[0052] Furthermore, the determination unit 115 may determine the degree of change in the user distance. The determination unit 115 may determine how much the distance between the user's face and the output unit 14 has increased or decreased between the two points in time used for the determination. Specifically, the determination unit 115 may determine how many centimeters the distance between the user's face and the output unit 14 has increased or decreased.

[0053] The determination unit 115 outputs information indicating the determination result to the output control unit 116. The information indicating the determination result includes information indicating that the distance between the user's face and the output unit 14 has become closer, moved away, or has not changed. The information indicating the determination result may further include information indicating the degree of change in the user distance.

[0054] Furthermore, while the output unit 14 is outputting the sound, the determination unit 115 refers to the distance information 121 and determines whether the user distance indicated in the distance information 121 is equal to or greater than a predetermined value. This determination may be made each time the determination unit 115 acquires information indicating that the distance information 121 has been updated from the measurement unit 114. If the user distance is equal to or greater than a predetermined value (for example, 1 m), the determination unit 115 decides to end the processing related to the second call registration, and outputs information indicating that the processing related to the second call registration is ended to each unit of the control unit 11. This ends the processing related to the second call registration in the destination floor registration device 1.

[0055] (output control unit 116) While the destination floor registration device 1 is performing control related to the second call registration, the output control unit 116 performs control related to the audio output and control related to the volume adjustment.

[0056] First, we will explain the control related to the audio output performed by the output control unit 116. When the reception unit 111 receives an input operation to instruct the start of audio guidance, it causes the output unit 14 to output audio including information indicating a floor. Specifically, the output control unit 116 causes the output unit 14 to output audio including information (floor information) indicating one floor that can be specified as a destination floor.

[0057] After outputting a voice including floor information indicating one floor, if the reception unit 111 does not receive an input operation specifying the notified one floor, the output control unit 116 causes the output unit 14 to output a voice including floor information indicating one floor that can be specified as a destination floor and has not yet been guided to.

[0058] For example, if an operation to specify a destination floor is not performed on second operation receiving unit 16 within a predetermined time (for example, within one second) after output control unit 116 causes output unit 14 to output a sound including floor information indicating the second floor, receiving unit 111 does not receive the second specifying operation to specify the second floor as the destination floor. In this case, output control unit 116 next causes output unit 14 to output a sound including floor information indicating the third floor.

[0059] The output control unit 116 repeats the process of outputting the voice including the floor information until all floors that can be specified as destination floors have been announced or the reception unit 111 accepts the second specification operation. As a result, the output unit 14 announces the floors that can be specified as destination floors one by one by voice. Note that the output control unit 116 may control the output unit 14 so that the announcement is made in order from the lowest floor among the floors that can be specified as destination floors.

[0060] After outputting the sound including floor information for all floors that can be designated as destination floors, and if the reception unit 111 has not received the second designation operation, the output control unit 116 decides to end the processing related to the second call registration. In this case, the output control unit 116 outputs information indicating that the processing related to the second call registration is to be ended to each unit of the control unit 11. This ends the processing related to the second call registration in the destination floor registration device 1. When the processing related to the second call registration is ended, the output control unit 116 stops the output unit 14 from outputting the sound.

[0061] If the reception unit 111 receives an input operation specifying a notified floor between the time when the output unit 14 notifies the first floor and the time when the next floor is notified, the output control unit 116 stops the output by the output unit 14.

[0062] Furthermore, when the reception unit 111 receives a second designation operation that designates one of the notified floors, the registration unit 112 registers a destination floor call with the designated floor as the destination floor. When the second designation operation is performed, the destination floor call based on that operation is registered, so the user does not need to hear any further voice guidance about floors. According to the above configuration, after the destination floor is designated by the user, the voice guidance about the floors stops. This prevents unnecessary voice guidance from continuing, reducing annoyance for the user.

[0063] After stopping the output of floor information by the output unit 14, the output control unit 116 may cause the output unit 14 to output the floor designated as the destination floor and a voice indicating that the floor has been designated as the destination floor. This allows the user to confirm the floor that they have designated as the destination floor.

[0064] Furthermore, the output control unit 116 receives allocation result information from the group management control device 2. Upon receiving the allocation result information, the output control unit 116 causes the output unit 14 to output a sound including information indicating the allocation result. Specifically, the output control unit 116 causes the output unit 14 to output a sound including information indicating that the registration of the destination floor call has been completed and the number of the elevator 4 assigned to the destination floor call.

[0065] After causing the output unit 14 to output a sound including information indicating the allocation result, the output control unit 116 decides to end the processing related to the second call registration, and outputs information indicating that the processing related to the second call registration is to be ended to each unit of the control unit 11. This ends the processing related to the second call registration in the destination floor registration device 1, and the output control unit 116 stops the output of the sound by the output unit 14. When the processing related to the second call registration is ended, the measurement unit 114 ends the measurement of the user distance, and the reception unit 111 becomes ready to receive a new first designation operation or start operation.

[0066] Next, control related to volume adjustment performed by the output control unit 116 will be described. While control related to output by the output unit 14 is being performed, that is, while the destination floor registration device 1 is performing control related to second call registration, the output control unit 116 performs control to adjust the volume of the sound to be output from the output unit 14. If volume control information 123 is stored in the storage unit 12, the output control unit 116 causes the output unit 14 to output the sound at a volume based on the volume control information 123. Note that if volume control information 123 is not stored in the storage unit 12, the output control unit 116 causes the output unit 14 to output the sound at a volume based on the reference volume information 122.

[0067] Furthermore, the output control unit 116 controls the volume of the sound to be output from the output unit 14 in accordance with the distance between the user and the output unit 14 measured by the measurement unit 114. The output control unit 116 determines how much to change the volume of the sound to be output from the output unit 14 based on the distance between the user and the output unit 14. In this way, the output control unit 116 controls the volume of the sound to be output from the output unit 14 based on the distance between the user and the output unit 14.

[0068] In a destination floor registration device 1 that provides voice guidance, the appropriate volume varies depending on the user and the environment around the destination floor registration device 1. For example, depending on the user's hearing ability, a voice at a preset volume may be easy or difficult for the user to hear. Furthermore, if the area around the destination floor registration device 1 is crowded or if other sounds are ringing around the destination floor registration device 1, the voice at the preset volume may be difficult for the user to hear. Furthermore, if the area around the destination floor registration device 1 is quiet, the user may find the voice at the preset volume annoying. In such cases, it is preferable to adjust the volume of the voice to be output.

[0069] Since users who request voice guidance are likely to be visually impaired or have concerns about their eyesight, a configuration in which the volume can be changed by an input operation such as pressing a button can be inconvenient for users. For example, if an input operation to adjust the volume is required, the voice guidance for the desired floor may end while the user is searching for the button to perform the operation to adjust the volume or while the user is performing the input operation to adjust the volume.

[0070] According to the destination floor registration device 1 of the present invention, the output control unit 116 controls the volume of the voice to be output depending on the distance to the user. As a result, if the user finds it difficult to hear the voice guidance or feels that the volume of the voice guidance is too loud, the user can adjust the volume of the voice by changing the distance from the output unit 14. Therefore, by using the destination floor registration device 1 of the present invention, convenience for users who require voice guidance can be improved.

[0071] The volume control by the output control unit 116 will be described in detail below. The output control unit 116 may adjust the volume of the sound to be output from the output unit 14 in accordance with a change in the measured user distance. Specifically, the output control unit 116 determines whether to increase or decrease the volume of the sound to be output from the output unit 14 based on the determination result of the determination unit 115 in accordance with a change in the measured user distance.

[0072] The output control unit 116 stores information indicating the determined volume in the storage unit 12 as volume control information 123. If volume control information 123 is already stored in the storage unit 12, the volume control information 123 is updated based on the newly determined volume. This allows the output control unit 116 to control the volume of the sound to be output from the output unit 14 based on the distance between the user and the output unit 14.

[0073] The output control unit 116 may perform control related to the adjustment of the volume every time it obtains a determination result from the determination unit 115. The output control unit 116 outputs the sound at a volume based on the updated volume control information 123, and therefore the volume of the sound output from the output unit 14 is adjusted in accordance with the change in the measured distance.

[0074] When it is determined that the user has approached the output unit 14, the output control unit 116 performs control to increase the volume of the sound to be output from the output unit 14. Specifically, when it is determined that the user has approached the output unit 14, the output control unit 116 determines to increase the volume and updates the volume control information 123. As a result, the output control unit 116 controls the volume of the sound to be output from the output unit 14 to increase.

[0075] When it is determined that the user has moved away from the output unit 14, the output control unit 116 performs control to lower the volume of the sound to be output from the output unit 14. Specifically, when it is determined that the user has moved away from the output unit 14, the output control unit 116 may decide to lower the volume and update the volume control information 123. In this way, the output control unit 116 controls the volume of the sound to be output from the output unit 14 to be lowered.

[0076] If it is determined that the distance between the user and the output unit 14 has not changed, the output control unit 116 determines not to change the volume of the sound to be output from the output unit 14. In this case, the volume control information 123 is not updated. Therefore, if the distance between the user and the output unit 14 has not changed, the volume of the sound to be output from the output unit 14 by the output control unit 116 does not change.

[0077] FIG. 5 is a diagram showing an example of the distance relationship between the face of a user (reference symbol P) and the destination floor registration device 1. In the example shown in FIG. 5, the user distance (reference symbol L2) in the state indicated by reference symbol 502 is smaller than the user distance (reference symbol L1) in the state indicated by reference symbol 501. Therefore, when the positional relationship between the user P and the destination floor registration device 1 changes from the state indicated by reference symbol 501 to the state indicated by reference symbol 502, the determination unit 115 determines that the user P has approached the output unit 14. In this case, the output control unit 116 controls the volume of the sound output from the output unit 14 to increase.

[0078] 5, the user distance (L3) in the state indicated by reference numeral 503 is greater than the user distance (L2) in the state indicated by reference numeral 502. Therefore, when the positional relationship between the user P and the destination floor registration device 1 changes from the state indicated by reference numeral 502 to the state indicated by reference numeral 503, the determination unit 115 determines that the user P has moved away from the output unit 14. In this case, the output control unit 116 controls the volume of the sound output from the output unit 14 to decrease.

[0079] Furthermore, the output control unit 116 may change the degree of change in the volume depending on the degree of change in the user distance. For example, in the example shown in FIG. 5 , when the user P and the destination floor registration device 1 change from the state indicated by reference numeral 502 to the state indicated by reference numeral 501, and when the user changes from the state indicated by reference numeral 502 to the state indicated by reference numeral 503, the user is farther away from the output unit 14 in both cases. However, the distance from the user to the output unit 14 is greater in the latter case than in the former case. Here, the output control unit 116 may control the volume of the sound output from the output unit 14 to be lower in the latter case than in the former case. Furthermore, the output control unit 116 may control the volume of the sound output from the output unit 14 to be higher in the latter case than in the former case, when the user changes from the state indicated by reference numeral 501 to the state indicated by reference numeral 502, compared to when the user changes from the state indicated by reference numeral 503 to the state indicated by reference numeral 502.

[0080] It is considered that the user desires a lower volume of sound when the user moves farther away from the output unit 14. It is also considered that the user desires a higher volume of sound when the user moves closer to the output unit 14. According to the above configuration, the output control unit 116 can change the volume of the sound to be output depending on how close the user is to or how far away from the output unit 14 the user is.

[0081] Furthermore, the output control unit 116 may adjust in stages the volume of the sound to be output from the output unit 14. For example, at least one threshold may be set in advance, and the output control unit 116 may adjust the volume of the sound to be output from the output unit 14 based on a change in the user distance and the threshold. The number of thresholds to be set may be 1, 10, or more.

[0082] As an example, three thresholds may be set. When the user's face and the output unit 14 come closer to each other by more than the smallest threshold and less than the second smallest threshold, the output control unit 116 may determine to increase the volume of the sound output from the output unit 14 by one level. As another example, when the user's face and the output unit 14 come farther apart by more than the second smallest threshold and less than the third smallest threshold, the output control unit 116 may determine to decrease the volume of the sound output from the output unit 14 by two levels.

[0083] The degree of change in volume based on the threshold value may be set appropriately. For example, the degree of change in volume by one level when the number of threshold values ​​set within a predetermined distance is 10 may be smaller than the degree of change in volume by one level when the number of threshold values ​​within the same distance is 1. Setting finer threshold values ​​allows the output control unit 116 to adjust the volume more precisely.

[0084] As described above, the output control unit 116 controls the volume of the audio to be output in accordance with changes in the distance to the user. This allows the user to adjust the volume of the audio to be output without performing any special operations, such as pressing a specific button, which may be difficult for some users. For example, the volume of the audio guidance can be adjusted by simply performing natural actions, such as moving closer to the output unit 14 if the sound is hard to hear, or moving away from the output unit 14 if the sound is too loud.

[0085] Furthermore, if the distance between the user's face and the output unit 14 becomes equal to or greater than a predetermined value while the output unit 14 is outputting audio, the output control unit 116 may stop the output by the output unit 14. While the output unit 14 is outputting audio, the determination unit 115 refers to the latest distance information 121 and determines whether the user distance indicated in the distance information 121 is equal to or greater than a predetermined value. If the user distance is equal to or greater than a predetermined value, the determination unit 115 decides to end the processing related to the second call registration, and outputs information indicating that the processing related to the second call registration is ended to each unit of the control unit 11. This ends the processing related to the second call registration in the destination floor registration device 1. When the processing related to the second call registration is ended, the output control unit 116 stops the output by the output unit 14.

[0086] While voice guidance is being provided by the output unit 14, there are cases where the user moves away from the destination floor registration device 1 before registering a destination floor call. According to the above configuration, if the user moves away from the output unit 14 of the destination floor registration device 1 while voice guidance is being provided by the output unit 14, the voice guidance ends. This reduces the possibility that, if the user stops registering a call while voice guidance is being provided by the output unit 14, the voice will continue to be output at a high volume, causing discomfort to other users.

[0087] As described above, while processing related to the second call registration is being performed, the destination floor registration device 1 provides voice guidance by controlling the volume of the voice output from the output unit 14 to be adjusted based on the distance to the user. As a result, while the user is performing an operation related to the second call registration, voice is output at a volume appropriate for the user, adjusted based on the distance between the user and the output unit 14.

[0088] Furthermore, when the processing related to the second call registration is completed, the measurement unit 114 deletes the volume control information 123. Therefore, after the processing related to one second call registration is completed, the volume of the voice output from the output unit 14 next becomes the volume based on the reference volume information 122, i.e., the preset volume. A volume appropriate for the first user is not necessarily appropriate for the second user. Here, according to the above configuration, when the second user performs an operation to start voice guidance after the first user performs second call registration, the voice is output from the output unit 14 at the preset volume, and the volume is adjusted based on the distance between the second user and the output unit 14. This allows the destination floor registration device 1 to provide voice guidance at a volume appropriate for each user.

[0089] <Example of processing flow performed by destination floor registration device 1> Fig. 6 is a flowchart showing an example of the flow of processing related to first call registration performed by the destination floor registration device 1. Fig. 7 is a flowchart showing an example of the flow of processing related to second call registration performed by the destination floor registration device 1. Fig. 8 is a flowchart showing an example of the flow of processing related to volume adjustment performed by the destination floor registration device 1. The flow of processing performed by the destination floor registration device 1 will be described below with reference to Figs. 6 to 8.

[0090] (Processing related to first call registration) First, an example of the flow of processing related to the first call registration will be described with reference to Fig. 6. During a period when no operation by the user is being accepted and the destination floor registration device 1 is not performing either the processing related to the first call registration or the processing related to the second call registration, the display control unit 113 displays a destination floor registration screen on the display unit 13. During this period, the accepting unit 111 can accept a first designation operation or a start operation.

[0091] The reception unit 111 waits for processing until it receives a first designation operation (YES in S1) or a start operation. The user can perform a first designation operation on the first operation reception unit 15 while the destination floor registration screen is displayed on the display unit 13. When the reception unit 111 receives the first designation operation performed on the first operation reception unit 15 (YES in S1: reception step), it identifies the floor designated as the destination floor by the first designation operation. The reception unit 111 outputs information indicating the identified floor to the registration unit 112. The reception unit 111 also stops receiving the first designation operation.

[0092] When the registration unit 112 acquires information indicating a floor from the reception unit 111, it registers a destination floor call. Specifically, the registration unit 112 generates a destination floor call in which the floor included in the acquired information is the destination floor. The destination floor call may include information indicating the destination floor, information indicating the departure floor which is the floor on which the destination floor registration device 1 is installed, and identification information for identifying the destination floor registration device 1. Next, the registration unit 112 transmits the generated destination floor call to the group management control device 2 (S2).

[0093] When the group management control device 2 receives a destination floor call, it assigns the optimal elevator number to the destination floor call based on the destination floor call and the operating status of the elevator 4. The group management control device 2 transmits assignment result information including information indicating the assigned elevator number to the destination floor registration device 1, which is the sender of the destination floor call. The group management control device 2 also transmits information indicating the departure floor and destination floor corresponding to the destination floor call to the elevator control device 3, which controls the elevator number assigned to the destination floor call. In this way, the elevator control device 3 controls the operation of the elevator 4 according to the registered destination floor call.

[0094] The display control unit 113 waits for processing until it receives allocation result information from the group management control device 2 (until it returns YES in S3). When it receives the allocation result information from the group management control device 2 (YES in S3), the display control unit 113 causes the display unit 13 to display an allocation result screen including an allocation result based on the allocation result information (S4). The allocation result screen includes information indicating that the registration of the destination floor call has been completed and information indicating the allocated car number.

[0095] The display control unit 113 displays the allocation result screen for a predetermined time, and then outputs information indicating that the processing related to the first call registration is to be terminated to each unit of the control unit 11. This terminates the processing related to the first call registration in the destination floor registration device 1. When the processing related to the first call registration is terminated, the display unit 13 displays the destination floor registration screen on the display unit 13. Furthermore, the reception unit 111 becomes ready to receive the first designation operation or the start operation.

[0096] (Processing related to second call registration) Next, an example of the flow of processing related to the second call registration will be described with reference to Fig. 7. During a period when no operation by the user is being accepted and the destination floor registration device 1 is not performing either the processing related to the first call registration or the processing related to the second call registration, the accepting unit 111 can accept a first specifying operation or a start operation.

[0097] The reception unit 111 waits for processing until it receives a first designation operation (YES in S1) or a start operation (YES in S11). At this time, the user can perform a start operation on the second operation reception unit 16. When the reception unit 111 receives the start operation performed on the second operation reception unit 16 (YES in S11: reception step), it transmits a service floor acquisition request to the group management control device 2 (S12). When the group management control device 2 receives the service floor acquisition request, it transmits service floor information to the destination floor registration device 1. When the reception unit 111 receives the service floor information (YES in S13), it stores the service floor information in the memory unit 12. After storing the service floor information in the memory unit 12, the reception unit 111 decides to start processing related to second call registration, and outputs the decision to each unit of the control unit 11. As a result, processing related to second call registration is started in the destination floor registration device 1. If the reception unit 111 does not receive information indicating a service floor after transmitting the service floor acquisition request (NO in S13), the reception unit 111 performs the process of S12 again.

[0098] When the process for the second call registration is started, the reception unit 111 stops receiving the start operation. When the measurement unit 114 receives information indicating the start of the process for the second call registration from the reception unit 111, the measurement unit 114 receives a signal from the sensor 17 at predetermined time intervals and starts measuring the user distance and updating the distance information 121.

[0099] When the output control unit 116 receives information indicating the start of processing related to the second call registration from the reception unit 111, it starts outputting audio from the output unit 14 (S14). When audio output starts, the output control unit 116 assigns 0 to variable N (S15). Next, the output control unit 116 references the floor information 124 and assigns a value indicating a floor identified based on variable N to variable X (S16). For example, if variable N is 0, floor X indicates the first basement floor. Next, the output control unit 116 determines whether floor X can be specified as a destination floor based on the service floor information (S17). For example, when floor information 124 shown in FIG. 4 is stored and floor X indicates the first basement floor, the output control unit 116 determines whether floor X can be specified as a destination floor. If floor X can be specified as a destination floor (YES in S17), the process proceeds to S18. If the Xth floor cannot be specified as the destination floor (NO in S17), the process proceeds to S21.

[0100] If the answer is YES in S17, the output control unit 116 causes the output unit 14 to notify the first floor. Specifically, the output control unit 116 causes the output unit 14 to output a sound including floor information indicating the Xth floor (S18: output control step). For example, if the Xth floor indicates the first basement floor, the output control unit 116 causes the output unit 14 to output a sound including floor information indicating the first basement floor.

[0101] The reception unit 111 can receive an input operation for designating the notified one floor from when the output unit 14 notifies the one floor until when the next floor is notified.

[0102] If a predetermined time has not elapsed after S18 (NO in S19), the reception unit 111 can receive a second designation operation. After one floor is notified in S18, if the user performs a second designation operation on the second operation reception unit 16 before the predetermined time has elapsed, the reception unit 111 receives the second designation operation to designate the floor notified in S18 as the destination floor (YES in S20).

[0103] If the second designation operation is not performed on the second operation acceptance unit 16 within a predetermined time after S18 (NO in S19), the acceptance unit 111 does not accept the second designation operation (NO in S20). If the predetermined time has passed after S18 without the acceptance unit 111 accepting the second designation operation (YES in S19), or if NO in S17, the output control unit 116 determines whether or not guidance has been given to all floors that can be designated as destination floors (S21). If guidance has not been given to all floors that can be designated as destination floors (NO in S21), in other words, if there are floors that have not yet been notified to the output unit 14, the output control unit 116 increments N by 1 (S22). After the processing of S22 is performed, the process returns to the processing of S16.

[0104] A specific example of voice output control will be described below, taking as an example a case where the floor information 124 shown in FIG. 4 is stored, the destination floor registration device 1 is installed on the first floor of a building, and the service floors are the first basement floor and the second to sixth floors above ground. If N=0 in S18, the X floor indicates the first basement floor. If the reception unit 111 does not receive a second designation operation within a predetermined time after the output unit 14 outputs voice including floor information indicating the first basement floor, the output control unit 116 next sets N=1. If N=1, the X floor indicates the first floor. Because the first floor cannot be designated as a destination floor, the output control unit 116 next sets N=2. If N=2, the X floor indicates the second floor. Because the second floor can be designated as a destination floor, the output control unit 116 causes the output unit 14 to output voice including floor information indicating the second floor. As a result, the floors are voice-guided one by one until the reception unit 111 receives the second specification operation (YES in S20) or until all floors that can be specified as destination floors have been guided (YES in S21).

[0105] If a predetermined time has not elapsed after S18 (NO in S19) and the reception unit 111 receives a second designation operation (YES in S20), the reception unit 111 outputs information indicating that the second designation operation has been received to the output control unit 116. The reception unit 111 also outputs information indicating the floor designated as the destination floor by the second designation operation to the registration unit 112. The floor designated as the destination floor by the second designation operation is the one floor notified in the immediately preceding S18.

[0106] When the output control unit 116 acquires information indicating that the second designation operation has been accepted, it stops outputting sound from the output unit 14 (S23). Furthermore, when the registration unit 112 acquires information indicating the floor designated as the destination floor by the second designation operation, it generates a destination floor call that designates that floor as the destination floor and the floor on which the destination floor registration device 1 is installed as the departure floor. Next, the registration unit 112 transmits the generated destination floor call and identification information of the destination floor registration device 1 that includes the registration unit 112 to the group management control device 2 (S24).

[0107] When the group management control device 2 receives a destination floor call, it assigns the elevator 4 number that is optimal for that destination floor call. The group management control device 2 also transmits assignment result information, including information indicating the elevator number assigned to the destination floor call, to the destination floor registration device 1 that is the sender of the destination floor call. The group management control device 2 also transmits information instructing the elevator 4 to operate based on the registered destination floor call to the elevator control device 3, which controls the elevator 4 number assigned to the destination floor call. Based on instructions from the group management control device 2, the elevator control device 3 controls the movement of the elevator 4 between floors and the opening and closing of the doors.

[0108] When the output control unit 116 receives the allocation result information from the group management control device 2 (YES in S25), it causes the output unit 14 to output the allocation result including information indicating the car number allocated to the destination floor call (S26). Note that the display control unit 113 may also cause the display unit 13 to display the allocation result.

[0109] After S26, the output control unit 116 decides to end the processing related to the second call registration. Subsequently, the output control unit 116 outputs information indicating that the processing related to the second call registration is to be ended to each unit of the control unit 11. As a result, the destination floor registration device 1 ends the processing related to the second call registration.

[0110] On the other hand, if a predetermined time has elapsed after S18 (YES in S19) and the output unit 14 has provided guidance on all floors that can be specified as destination floors under the control of the output control unit 116 (YES in S21), the output control unit 116 decides to end the processing related to the second call registration. In other words, if a second specifying operation is not performed on the second operation accepting unit 16 until voice guidance has been completed for all floors that can be specified as destination floors, the output control unit 116 decides to end the processing related to the second call registration. Subsequently, the output control unit 116 outputs information indicating that the processing related to the second call registration is to be ended to each unit of the control unit 11. As a result, the destination floor registration device 1 ends the processing related to the second call registration.

[0111] When the process related to the second call registration is completed, the output control unit 116 stops the output by the output unit 14 (S27). Furthermore, the measurement unit 114 ends the measurement of the user distance and deletes the distance information 121 stored in the memory unit 12. Furthermore, the display control unit 113 causes the display unit 13 to display a destination floor registration screen, and the reception unit 111 becomes ready to receive the first designation operation or the start operation.

[0112] (Volume adjustment processing) An example of the flow of processing related to volume adjustment performed by the destination floor registration device 1 while output is being performed by the output unit 14 will be described below with reference to Fig. 8. While processing related to second call registration is being performed, the destination floor registration device 1 performs the processing shown in Fig. 8. As a result, the volume of the sound output from the output unit 14 in S18 and S26 is controlled based on the user distance.

[0113] 7, in other words, while the output unit 14 is outputting audio, the measurement unit 114 acquires a signal from the sensor 17 and measures the user distance (S31: measurement step). The measurement unit 114 also updates the distance information 121 in the storage unit 12 based on the measured user distance. After updating the distance information 121, the measurement unit 114 outputs information indicating that the distance information 121 has been updated to the determination unit 115.

[0114] When the determination unit 115 receives information indicating that the distance information 121 has been updated from the measurement unit 114, the determination unit 115 determines whether the user distance is equal to or greater than a predetermined value (S32). If the user distance is less than the predetermined value (NO in S32), the determination unit 115 makes a determination based on the change in the user distance, and outputs information indicating the determination result to the output control unit 116.

[0115] Specifically, the determination unit 115 acquires the latest distance information 121 and the distance information 121 a predetermined time before the latest, and determines whether or not the user has approached the output unit 14 based on the distance information 121 (S33). If the user has approached the output unit 14 (YES in S33), the determination unit 115 outputs information including a determination result indicating that the user has approached the output unit 14 to the output control unit 116.

[0116] When output control unit 116 acquires from determination unit 115 a determination result indicating that the user has approached output unit 14, output control unit 116 performs control to increase the volume of the sound to be output from output unit 14 (S34). Specifically, output control unit 116 determines to increase the volume of the sound to be output from output unit 14, and updates volume control information 123 so that the volume of the sound to be output from output unit 14 is increased. The volume of the sound that output control unit 116 outputs from output unit 14 is based on the latest volume control information 123. Therefore, if the determination in S33 is YES, the volume of the sound to be output from output unit 14 after volume control information 123 is updated is controlled to be higher than before volume control information 123 was updated.

[0117] On the other hand, if the user is not approaching the output unit 14 (NO in S33), the determination unit 115 determines whether or not the user has moved away from the output unit 14 (S35). If the user has moved away from the output unit 14 (YES in S35), the determination unit 115 outputs information including a determination result indicating that the user has moved away from the output unit 14 to the output control unit 116.

[0118] When the output control unit 116 acquires from the determination unit 115 a determination result indicating that the user has moved away from the output unit 14, the output control unit 116 performs control to lower the volume of the sound to be output from the output unit 14 (S36). Specifically, the output control unit 116 determines to lower the volume of the sound to be output from the output unit 14, and updates the volume control information 123 so that the volume of the sound to be output from the output unit 14 is lower. The volume of the sound that the output control unit 116 outputs from the output unit 14 is based on the latest volume control information 123. Therefore, if the determination in S35 is YES, the volume of the sound to be output from the output unit 14 after the volume control information 123 is updated is controlled to be lower than the volume before the volume control information 123 was updated.

[0119] If the result of S35 is NO, that is, if the user is neither approaching nor moving away from the output unit 14, the determination unit 115 determines that the user distance has not changed. After S34 or S36, or if the result of S35 is NO, the process returns to S31.

[0120] In S32, if the user distance is equal to or greater than a predetermined value (YES in S32), the determination unit 115 decides to end the processing related to the second call registration, and outputs information indicating that the processing related to the second call registration is ended to each unit of the control unit 11. This ends the processing related to the second call registration in the destination floor registration device 1. When the processing related to the second call registration is ended, the output control unit 116 stops output by the output unit 14. Furthermore, the measurement unit 114 ends measurement of the user distance, and deletes the distance information 121 stored in the memory unit 12. Furthermore, the display control unit 113 displays a destination floor registration screen on the display unit 13, and the reception unit 111 becomes ready to receive a first designation operation or a start operation.

[0121] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0122] Fig. 9 is a block diagram showing the configuration of an elevator system 100A including a destination floor registration device 1A according to a second embodiment of the present invention. The elevator system 100A differs from the elevator system 100A according to the first embodiment in that it includes a destination floor registration device 1A instead of the destination floor registration device 1. As shown in Fig. 9, the destination floor registration device 1A differs from the destination floor registration device 1 according to the first embodiment in that it includes a control unit 11A and a storage unit 12A instead of the control unit 11 and the storage unit 12, and further includes an imaging unit 18. The destination floor registration device 1A according to the second embodiment controls the volume based on the movement (gesture) performed by the user in addition to controlling the volume based on the user distance.

[0123] The imaging unit 18 is a camera capable of capturing an image of a user. The imaging unit 18 is provided in a position where it can capture an image of a user operating the destination floor registration device 1A. For example, the imaging unit 18 may be provided near the sensor 17. The imaging unit 18 may be a camera capable of capturing moving images, or may be a camera capable of capturing still images. The following describes an example in which the imaging unit 18 is a camera capable of capturing moving images as an image of the user.

[0124] The storage unit 12A stores an estimation model M and motion information 125 in addition to the information stored in the storage unit 12 according to the first embodiment. The estimation model M is a trained estimation model trained using a dataset in which a video of a person performing a specific motion is used as an explanatory variable for learning and information indicating the type of the specific motion is used as a target variable for learning. The motion information 125 is information in which information indicating the type of motion is associated with information indicating whether the motion is a motion that increases the volume or a motion that decreases the volume. The information indicating the type of motion may be information indicating the name of the type of motion.

[0125] The control unit 11A differs from the control unit 11 according to the first embodiment in that it includes an output control unit 116A instead of the output control unit 116, and further includes a detection unit 117.

[0126] The detection unit 117 detects the type of action performed by the user. Specifically, when processing related to second call registration is started in the destination floor registration device 1A, the detection unit 117 acquires a moving image of the user captured by the imaging unit 18. The detection unit 117 uses the moving image of the user captured by the imaging unit 18 as input data and detects the type of action performed by the user by using the estimation model M stored in the storage unit 12A. When the detection unit 117 detects that the user has performed a specific action, it outputs information indicating the type of action performed by the user to the output control unit 116A.

[0127] If the imaging unit 18 is a camera capable of capturing still images, the detection unit 117 may detect the type of movement performed by the user using as input data a still image of the user captured by the imaging unit 18. In this case, the estimation model M may be a trained estimation model trained using a dataset in which a still image of a person performing a specific movement (gesture) is used as an explanatory variable for learning, and information indicating the type of the specific movement is used as a target variable for learning.

[0128] The output control unit 116A controls the volume of the sound to be output from the output unit 14 based on the type of action performed by the user. Specifically, when the output control unit 116A acquires information indicating the type of action performed by the user from the detection unit 117, the output control unit 116A refers to the action information 125 in the storage unit 12A and identifies information indicating how to control the volume corresponding to the detected type of action. The output control unit 116A updates the volume control information 123 based on the identified information and controls the volume of the sound to be output from the output unit 14.

[0129] The specific action may be, for example, an action indicating that sound is hard to hear. Furthermore, in the action information 125, information indicating the type of action indicating that sound is hard to hear may be associated with information indicating that the action is a target for increasing the volume. When the user performs an action indicating that sound is hard to hear, specifically, an action such as placing a hand over an ear or tilting the head, the detection unit 117 detects the action. When the detection unit 117 detects the action, the output control unit 116A updates the volume control information 123 and performs control to increase the volume of the sound output from the output unit 14.

[0130] Furthermore, the specific action may be, for example, an action indicating that the sound is loud. Furthermore, in the action information 125, information indicating the type of action indicating that the sound is loud may be associated with information indicating that the action is a target for lowering the volume. When the detection unit 117 detects that the user has performed an action indicating that the sound is loud, specifically, an action such as covering one's ears, the output control unit 116A updates the volume control information 123 and performs control to lower the volume of the sound output from the output unit 14.

[0131] If the user is already in a position close to the destination floor registration device 1A, there is a possibility that operation will be hindered if the user moves even closer to the destination floor registration device 1A. According to the above configuration, even if the user is in such a position, the user can hear the sound at a louder volume by performing a predetermined action without changing the distance to the output unit 14.

[0132] Furthermore, if the user is already located far away from destination floor registration device 1A, further movement away from destination floor registration device 1A may cause operational problems. According to the above configuration, even if the user is located in such a position, the user can hear the sound at an even lower volume by performing a predetermined action without changing the distance from output unit 14.

[0133] As described above, the output control unit 116A can adjust the volume according to the user's actions. This allows the output control unit 116A to output sound at an appropriate volume from the output unit 14 based on the user's actions, even if the distance between the user and the output unit 14 does not change.

[0134] <Example of processing flow performed by destination floor registration device 1> 10 is a flowchart showing an example of the flow of processing related to volume adjustment performed by the destination floor registration device 1 A. The flow of processing performed by the destination floor registration device 1 A will be described below with reference to FIG.

[0135] While the process related to the second call registration is being performed, the destination floor registration device 1A can perform the process shown in Fig. 10 in addition to the process related to volume adjustment based on the user distance shown in Fig. 8, and control the volume of the voice output by the output unit 14. The destination floor registration device 1A repeats the process shown in Fig. 10 until the voice guidance by the output unit 14 ends.

[0136] 7, the detection unit 117 acquires an image of the user captured by the imaging unit 18 (S41). Based on the acquired image, the detection unit 117 detects a movement performed by the user using the estimation model M. Next, the detection unit 117 determines whether or not a specific movement by the user has been detected (S42). If a specific movement by the user has not been detected (NO in S42), the process returns to S41.

[0137] If a specific action is detected (YES in S42), the detection unit 117 outputs information indicating the type of action performed by the user to the output control unit 116A.

[0138] When output control unit 116A acquires information indicating the type of action performed by the user from detection unit 117, it refers to action information 125 in storage unit 12A. Output control unit 116A determines whether the identified action is an action that targets turning up the volume (YES in S43) or an action that targets turning down the volume (NO in S43). If the action detected by detection unit 117 is an action that targets turning up the volume (YES in S43), output control unit 116A performs control to turn up the volume output from output unit 14 (S44). The specific content of the control to turn up the volume is the same as the processing of S34 in FIG. 8, and therefore will not be described here.

[0139] On the other hand, if the action detected by detection unit 117 is not an action that is targeted for increasing the volume (NO in S43), that is, if the action is an action that is targeted for decreasing the volume, output control unit 116A performs control to decrease the volume output from output unit 14 (S45). The specific content of the control to decrease the volume is the same as the processing of S35 in Fig. 8, and therefore a description thereof will be omitted here. After S44 or S45, the process returns to S41.

[0140] [Modification] (Variation 1) In the first and second embodiments, the measurement unit 114 measures the user distance based on the signal acquired from the sensor 17, but the method by which the measurement unit 114 measures the user distance is not limited to this. For example, the destination floor registration device 1 may include an imaging unit 18 that captures an image of the user. Furthermore, the measurement unit 114 may measure the user distance based on a moving image captured by the imaging unit 18.

[0141] (Variation 2) In embodiments 1 and 2, when the reception unit 111 receives a start operation, the output control units 116 and 116A may control the volume of the sound to be output from the output unit 14 based on the user distance at the time the reception unit 111 receives the start operation.

[0142] The distance from the output unit 14 to the user's ears varies depending on the height of the user, and therefore, even in the same environment, at the same volume, and with the same hearing ability, different users may hear sounds differently.

[0143] According to the above configuration, the volume is adjusted based on the user distance at the time when an input operation to instruct the start of voice guidance is accepted. For example, if the user distance is equal to or greater than a predetermined distance when the user stands in front of the destination floor registration device 1, such as when the user is tall, the output control units 116 and 116A control to increase the volume even if the distance between the user's face and the output unit has not changed. Also, for example, if the user distance is less than a predetermined distance when the user stands in front of the destination floor registration device 1, such as when the user is short, the output control units 116 and 116A control to decrease the volume even if the user distance has not changed. This allows the output control units 116 and 116A to output voice at an appropriate volume according to the user's height.

[0144] (Variation 3) In the first and second embodiments, the output unit 14 may be a directional speaker having directivity directed toward a direction in which a user performing an input operation may be present.

[0145] If the sound output from the output unit 14 is loud, it may cause discomfort to people in the vicinity. With the above configuration, the output unit 14 is a directional speaker, so even if the volume of the output sound is loud, it is difficult for people other than the user to hear the sound. This makes it possible to output sound at a volume appropriate for the user while reducing the possibility of causing discomfort to others.

[0146] (Variation 4) In the first and second embodiments, during the period in which the processing related to the second call registration is being performed, the accepting unit 111 may be able to accept the first specifying operation, or may not be able to accept the first specifying operation.

[0147] If the reception unit 111 is capable of receiving the first designation operation during the period in which processing related to the second call registration is being performed, the display control unit 113 displays the destination floor registration screen on the display unit 13 during that period. Users who use the voice guidance are not limited to those who cannot see the screen displayed on the display unit 13 at all, and there may be users who can check the contents of the display unit 13 while listening to the voice guidance and perform input operations on the first operation reception unit 15. According to the above configuration, the reception unit 111 can receive both the first designation operation and the second designation operation by the user while the voice guidance is being performed. Therefore, the user can register a destination floor call in a manner that is easy for them to operate.

[0148] On the other hand, the reception unit 111 may be unable to receive the first designation operation while the processing related to the second call registration is being performed. In this case, during this period, the display control unit 113 may display a message indicating that voice guidance is being performed on the display unit 13 instead of the destination floor registration screen. According to the above configuration, even if another user interrupts while a user is listening to voice guidance and performs a first designation operation on the first operation reception unit 15, the reception unit 111 does not accept the first designation operation. This reduces the possibility of a situation occurring in which a user listening to voice guidance is unable to register a destination floor call.

[0149] (Variation 5) In the second embodiment, the user's actions detected by the detection unit 117 are not limited to those described above. For example, the detection unit 117 may detect an action by the user of approaching the output unit 14 or an action by the user of moving away from the output unit 14. If the detection unit 117 can detect these actions, the determination unit 115 may determine a change in the user distance based on the detection result of the detection unit 117.

[0150] (Variation 6) In the first and second embodiments, the configuration has been described as an example in which the output control units 116 and 116A cause the output unit 14 to output voice guidance for floors that can be designated as destination floors based on the service floor information and floor information 124, but this is not limiting. For example, the output control unit 116 may cause the output unit 14 to provide voice guidance for all floors included in the floor information 124 one by one until a second designation operation is performed on the second operation receiving unit 16.

[0151] In the above configuration, if the reception unit 111 receives a second designation operation before a predetermined time has elapsed after one floor has been notified from the output unit 14 under the control of the output control unit 116, the registration unit 112 determines whether the floor designated by the second designation operation is a service floor (whether it can be designated as a destination floor). If the floor designated by the second designation operation is a service floor, the registration unit 112 generates a destination floor call with the designated floor as the destination floor. Then, the process proceeds to S23 shown in FIG. 7.

[0152] On the other hand, if the floor specified by the second specifying operation is not a service floor, the registration unit 112 does not generate a destination floor call and rejects the registration of the destination floor call. The registration unit 112 outputs information indicating that the registration of the destination floor call has been rejected to the output control unit 116. Upon receiving this information, the output control unit 116 causes the output unit 14 to output a voice message indicating that the floor specified by the second specifying operation cannot be specified as a destination floor, such as a message such as "You cannot stop at the currently registered floor." Thereafter, the destination floor registration device 1 may proceed to the processing of S22 shown in FIG. 7, or may end the processing.

[0153] According to the above configuration, if a user specifies a floor other than a service floor in the second specification operation, the user can understand that elevator 4 will not stop at the floor specified by the user, thereby improving usability.

[0154] [Software implementation example] The functions of the destination floor registration device 1, 1A (hereinafter referred to as the "device") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device (particularly each part included in the control unit 11, 11A).

[0155] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0156] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0157] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.

[0158] Furthermore, each process described in each of the above embodiments may be executed by AI (Artificial Intelligence). In this case, the AI ​​may run on the control device or on another device (for example, an edge computer or a cloud server).
