[0001] The present invention relates to a terminal operation management device, a terminal operation management method, and a terminal operation management program. [Background technology]

[0002] Conventionally, there is known a technique in which a plurality of operation devices and a plurality of displays are connected to the main body of a computer system by cables, and each operation device can exclusively use one of the plurality of displays (see, for example, Patent Document 1). Furthermore, in a display device that simultaneously displays multiple screens on a single display, a technique is known in which the positions of multiple remote controls relative to the display are identified and the screen to be operated by each remote control is the screen closest to the remote control (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 11-503849 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-34977 Summary of the Invention [Problem to be solved by the invention]

[0004] In the configuration disclosed in Patent Document 1, the combination of a display device and an operation device that operates the display device is determined by the connection state of the cable, and therefore, it does not support operation of the display device by a communication terminal that performs wireless communication. Furthermore, in the configuration disclosed in Patent Document 2, the closest screen among multiple screens displayed on the display device is selected as the remote control to be operated by the remote control, which causes the inconvenience that a remote control located far away from the display device or diagonally in front of the display device, outside the viewing angle of the display device, may be set as the remote control to operate the display device against the user's will. The present invention has been made in consideration of this background, and aims to provide a terminal operation management device, a terminal operation management method, and a terminal operation management program that can set a combination of a display device and a communication terminal that operates the display device while preventing it from going against the user's wishes. [Means for solving the problem]

[0005] A first aspect for achieving the above object is a terminal operation management device that includes a communication terminal position recognition unit that recognizes the position of a communication terminal present in the vicinity of a display device relative to the display device, and a terminal operation feasibility determination unit that enables the communication terminal to operate the display device when the position of the communication terminal relative to the display device is a predetermined position.

[0006] In the above terminal operation management device, the operation of the display device by the communication terminal may include an operation for using content displayed on the display device.

[0007] In the above-mentioned terminal operation management device, the communication terminal position recognition unit may be configured to recognize the position of the communication terminal relative to the display device based on measurement information of the distance between the display device and the communication terminal and the angle from a predetermined reference direction in the direction from the display device to the communication terminal.

[0008] In the above terminal operation management device, the predetermined position may be a position within a usage area set around the display device.

[0009] In the terminal operation management device, the utilization area may be set on a display direction side of the display device.

[0010] In the above-mentioned terminal operation management device, the terminal operation feasibility determination unit may be configured so that, when the communication terminal is located within the usage area and is capable of operating the display device by the communication terminal, if the communication terminal moves outside the usage area, the state in which the communication terminal can operate the display device is maintained until a predetermined time has elapsed from the time the communication terminal moved outside the usage area, or until a predetermined cancellation operation is performed by the user of the communication terminal.

[0011] In the above-mentioned terminal operation management device, the terminal operation feasibility determination unit may be configured to enable operation of the display device for all of the communication terminals present within the usage area when multiple communication terminals are present within the usage area.

[0012] In the above-mentioned terminal operation management device, the terminal operation possibility determination unit may be configured to enable operation of the display device for only one of the communication terminals present in the usage area when multiple communication terminals are present in the usage area.

[0013] In the above-mentioned terminal operation management device, the terminal operation feasibility determination unit may be configured to, when there are multiple communication terminals within the usage area, individually determine for each communication terminal whether or not operation of the display device is possible based on the functions possessed by the communication terminal.

[0014] In the above-mentioned terminal operation management device, the communication terminal position recognition unit may individually recognize the position of the communication terminal relative to the display device for each of the plurality of display devices, and the terminal operation feasibility determination unit may individually determine, for each of the plurality of display devices, whether the communication terminal is in the specified position relative to the display device, and individually determine whether or not to allow the communication terminal to operate the display device.

[0015] In the above-described terminal operation management device, the terminal operation permission determining unit may be configured to exclude the display devices that are not displaying a screen from the determination of whether or not to allow operation by the communication terminal.

[0016] In the above-mentioned terminal operation management device, the specified position may be a position within a usage area set for each display device around the display device, and the device may be configured to include a usage area change unit that changes the usage area depending on the number or placement position of the display devices displaying the screen.

[0017] In the above-mentioned terminal operation management device, the specified position may be a position within a usage area set for each display device around the display device, and the terminal operation feasibility determination unit may be configured to, for a first display device and a second display device included in the plurality of display devices, when the communication terminal is located within a first usage area, which is the usage area set for the first display device, allowing the communication terminal to operate the first display device, and when a change in the position of the communication terminal causes the position of the communication terminal to move into a second usage area, which is the usage area set for the second display device, the terminal operation feasibility determination unit disables the communication terminal from operating the first display device, enables the communication terminal to operate the second display device, and switches the output destination of the content displayed on the first display device from the first display device to the second display device.

[0018] A second aspect for achieving the above object is a terminal operation management method executed by a computer, which includes a communication terminal position recognition step for recognizing the position of a communication terminal present in the vicinity of a display device relative to the display device, and a terminal operation feasibility determination step for enabling the communication terminal to operate the display device when the position of the communication terminal relative to the display device is a predetermined position.

[0022] [1. Usage of terminal operation management device] A usage mode of the terminal operation management device 3 of this embodiment will be described with reference to Fig. 1. The terminal operation management device 3 of this embodiment is configured as part of the functions of a display control device 2 mounted on a vehicle 100. The display control device 2 is, for example, a control unit of a DA (Display Audio) 1 equipped with a display device. The DA1 is equipped with the display control device 2 and a display device whose image and sound output is controlled by the display control device 2. Fig. 1 shows a situation in which a user U1 is seated in the driver's seat 41, a user U2 is seated in the passenger seat 42, a user U3 is seated in the left rear seat 43, and a user U4 is seated in the right rear seat 44.

[0023] In this embodiment, the vehicle 100 is equipped with the following display devices controlled by the display control device 2: a center display device 72 arranged in the center of the dashboard, a passenger seat display device 60a arranged in front of the passenger seat 42, a left rear seat display device 60b arranged in front of the left rear seat 43, and a right rear seat display device 60c arranged in front of the right rear seat 44. User U2 carries a communication terminal 50a, user U3 carries a communication terminal 50b, and user U4 carries a communication terminal 50c.

[0024] Hereinafter, the passenger seat display device 60a, the left rear seat display device 60b, and the right rear seat display device 60c will be collectively referred to as display device 60, the communication terminals 50a to 50c will be collectively referred to as communication terminal 50, and the users U2 to U4 will be collectively referred to as user U. The display device 60 has a function of performing wireless communication with the communication terminal 50 according to communication standards such as Bluetooth (registered trademark) and UWB (Ultra-Wide Band). The communication terminal 50 includes communication terminals having an operation function via wireless communication, such as smartphones, mobile phones, game controllers, and wireless headphones.

[0025] Vehicle 100 is also equipped with a front seat camera 70 that captures an area including driver's seat 41 and passenger seat 42, and a rear seat camera 71 that captures an area including left rear seat 43 and right rear seat 44. Terminal operation management device 3 executes a process for determining whether display device 60 can be operated by communication terminal 50.

[0026] [2.Configuration of terminal operation management device] The configuration of the terminal operation management device 3 will be described with reference to Fig. 2. The display control device 2 includes a processor 10, a memory 20, a communication unit 30, etc. The display control device 2 is connected to a front seat camera 70, a rear seat camera 71, a center display device 72, a passenger seat display device 60a, a left rear seat display device 60b, and a right rear seat display device 60c.

[0027] The passenger seat display device 60a includes a communication unit 61a that performs wireless communication with the communication terminal 50. Similarly, the left rear seat display device 60b includes a communication unit 61b, and the right rear seat display device 60c includes a communication unit 61c. Hereinafter, the communication units 61a, 61b, and 61c will be collectively referred to as the communication unit 61. Note that the communication unit 61 that performs wireless communication with the communication terminal 50 may be located in a location other than the display device 60. For example, the communication unit 61 may be located in multiple locations within the vehicle, or may be located only at the front of the vehicle (at the position of DA1).

[0028] The communication unit 30 is, for example, a TCU (Telematics Control Unit), and downloads data of various contents (games, videos, music, etc.) from the content server 210 by communicating with the content server 210 via the communication network 200. The memory 20 stores a program 21 for controlling the DA1. The program 21 includes the terminal operation management program of the present disclosure.

[0029] By reading and executing program 21, processor 10 functions as communication terminal location recognition unit 11, terminal operation feasibility determination unit 12, utilization area change unit 13, and content output unit 14. Communication terminal location recognition unit 11, terminal operation feasibility determination unit 12, and utilization area change unit 13 constitute terminal operation management device 3.

[0030] The processing executed by the communication terminal position recognition unit 11 corresponds to the communication terminal position recognition step in the terminal operation management method of the present disclosure, and the processing executed by the terminal operation feasibility determination unit 12 corresponds to the terminal operation feasibility determination step in the terminal operation management method of the present disclosure.

[0031] The communication terminal position recognition unit 11 recognizes the position of the communication terminal 50 present in the vicinity relative to each of the multiple display devices 60. The communication terminal position recognition unit 11 calculates the distance between the display device 60 and the communication terminal 50 based on the reception level of radio waves by the communication unit 61. The communication terminal position recognition unit 11 also calculates the angle of the direction from the display device 60 to the communication terminal 50 with respect to a reference direction of the display device 60 (for example, the front direction of the display device 60) based on a combination of the distances between the communication terminal 50 and multiple antennas provided in the communication unit 61. The communication terminal position recognition unit 11 then recognizes the position of the communication terminal 50 relative to the display device 60 based on the distance between the display device 60 and the communication terminal 50 and the angle of the direction from the display device 60 to the communication terminal. Note that the method for recognizing the position of the communication terminal 50 relative to the display device 60 is not limited to the above-described method, and other recognition methods may be used, such as calculating the distance and angle from the time required from transmission to reception or the time difference and phase difference when receiving signals using multiple antennas.

[0032] As shown in FIG. 3 , the terminal operation permission determining unit 12 determines whether the position of the display device 60 recognized by the communication terminal position recognizing unit 11 is within the usable area Ar set in front of the display surface 65 of the display device 60. When the position of the communication terminal 50 is within the usable area Ar, as shown in speech bubble B1, the terminal operation permission determining unit 12 allows the communication terminal 50 to operate the display device 60. Here, when the terminal operation permission determining unit 12 determines that the communication terminal 50 is within the usable area Ar, it may display on the display device 60 that the operation by the communication terminal 50 is permitted. Alternatively, it may display on the display device 60 a message requesting a specific operation (such as pressing a button or tapping a notification) from the communication terminal 50, and permit the communication terminal 50 to operate the display device 60 upon receiving a specific operation input from the communication terminal 50. On the other hand, as shown in speech bubble B2, when the position of the communication terminal 50 is outside the usable area Ar, the terminal operation permission determining unit 12 disables the communication terminal 50 from operating the display device 60.

[0033] As shown in Fig. 2, an available area Ara is set for the passenger seat display device 60a, an available area Arb is set for the left rear seat display device 60b, and an available area Arc is set for the right rear seat display device 60c. The example in Fig. 2 shows a state in which the passenger seat display device 60a can be operated by the communication terminal 50a, the left rear seat display device 60b can be operated by the communication terminal 50b, and the right rear seat display device 60c can be operated by the communication terminal 50c.

[0034] The usage area change unit 13 changes the usage area Ar depending on the number or positions of the display devices 60 that are displaying their screens. FIG. 4 shows a case where the left rear seat display device 60b is displaying content and the right rear seat display device 60c is not displaying content (screen OFF state). In this case, the usage area change unit 13 expands the usage area Arb set for the left rear seat display device 60b toward the right rear seat display device 60c, as indicated by arrow E. This allows, for example, when user U3 (see FIG. 1) sitting in the left rear seat 43 shifts his / her seating position toward the right rear seat 44 during a break, user U3 can still operate the left rear seat display device 60b using the communication terminal 50b, thereby improving convenience for user U3.

[0035] [3.Determining whether or not to operate the terminal] The procedure for the process of determining whether or not to allow terminal operation, which is executed by the terminal operation management device 3, will be described with reference to the flowchart shown in Fig. 5. When the DA1 is in a power-on state, the terminal operation management device 3 repeatedly executes the process according to the flowchart shown in Fig. 5 for each of the plurality of display devices 60, and determines whether or not the communication terminal 50 can operate the display device 60.

[0036] 5, communication terminal location recognition unit 11 searches for communication terminal 50 present in the vicinity based on the reception status of radio waves by communication unit 61 of display device 60. In the following step S2, if communication terminal location recognition unit 11 detects communication terminal 50, it proceeds to step S3, and if communication terminal 50 is not detected, it proceeds to step S1.

[0037] In step S3, communication terminal position recognition unit 11 calculates the distance between display device 60 and communication terminal 50, and the angle from the reference direction of the direction from display device 60 to communication terminal 50, as described above. In the following step S4, communication terminal position recognition unit 11 recognizes the position of communication terminal 50 relative to display device 60 in accordance with the calculated distance and angle.

[0038] In the next step S5, the terminal operation feasibility determining unit 12 determines whether the position of the communication terminal 50 relative to the display device 60 is within the available area Ar, as described above with reference to Fig. 3. Then, if the position of the communication terminal 50 is within the available area Ar, the terminal operation feasibility determining unit 12 proceeds to step S6, and if the position of the communication terminal 50 is outside the available area Ar, the terminal operation feasibility determining unit 12 proceeds to step S7.

[0039] In step S6, terminal operation feasibility determining unit 12 enables operation of display device 60 by communication terminal 50. As a result, as shown in balloon B1 in FIG. 3, operation of display device 60 by communication terminal 50 becomes possible.

[0040] 4. Other Embodiments Another embodiment of the process for determining whether or not the communication terminal 50 can operate the display device 60 will be described with reference to FIGS.

[0041] FIG. 6 illustrates a case where the left rear seat display device 60b is displaying content, and the right rear seat display device 60c is not displaying content (screen-off state). In this case, the terminal operation possibility determining unit 12 excludes the right rear seat display device 60c, whose screen is off, from the determination of whether or not operation by the communication terminal 50 is possible. As a result, the left rear seat display device 60b, which is displaying content, can be operated by the communication terminal 50b located within the usage area Arb set for the left rear seat display device 60b. On the other hand, the right rear seat display device 60c, whose screen is off, cannot be operated by the communication terminal 50c located within the usage area Arc set for the right rear seat display device 60c. As a result, for example, when a user U4 (see FIG. 1) carrying a communication terminal 50c gets into the vehicle 100, it is possible to prevent the communication terminal 50c from automatically operating the right rear seat display device 60c against the user U4's will and starting to display content on the right rear seat display device 60c.

[0042] FIG. 7 illustrates a case in which user U3 (see FIG. 1), who was seated in left rear seat 43 carrying communication terminal 50b, moves to right rear seat 44, causing communication terminal 50b to move from within usage area Arb set for left rear seat display device 60b to within usage area Arc set for right rear seat display device 60c. In FIG. 7, left rear seat display device 60b corresponds to the first display device of the present disclosure, and usage area Arb corresponds to the first usage area of ​​the present disclosure. Also, right rear seat display device 60c corresponds to the second display device of the present disclosure, and usage area Arc corresponds to the second usage area of ​​the present disclosure. In this case, terminal operation permission determining unit 12 disables operation of left rear seat display device 60b by communication terminal 50b, as shown in speech bubble B7, and enables operation of right rear seat display device 60c by communication terminal 50b, as shown in speech bubble B8.

[0043] Furthermore, as shown in speech bubble B9, terminal operation permission determining unit 12 switches the output destination of the content that was output and displayed on left rear seat display device 60b by content output unit 14 to right rear seat display device 60c. This allows user U4, who has moved from left rear seat 43 to right rear seat 44, to continue viewing the content that he or she was viewing on left rear seat display device 60b on right rear seat display device 60c.

[0044] 8 shows a case where the communication terminal 50, which was present within the usage area Ar set for the display device 60, temporarily moves out of the usage area Ar. In this case, the terminal operation possibility determining unit 12 maintains a state in which the communication terminal 50 can operate the display device 60 until a predetermined time has elapsed since the communication terminal 50 moved out of the usage area Ar. This prevents the communication terminal 50 from being unable to operate the display device 60 when the user U temporarily moves seats, for example, thereby improving convenience for the user U.

[0045] Fig. 9 shows a case where multiple communication terminals exist within the usage area Ar set for the display device 60. Fig. 9 shows a case where, in addition to the above-mentioned communication terminal 50, a gaming controller 90 and wireless headphones 91 exist as communication terminals within the usage area Ar.

[0046] In this case, the terminal operation propriety determining unit 12 may execute the following multiple terminal compatible processes 1 to 3. Multiple terminal support 1 . . . The terminal operability determining unit 12 enables operation of the display device 60 for all of the multiple communication terminals (communication terminal 50, gaming controller 90, and wireless headphones 91 in FIG. 9) present within the available area Ar. Support for multiple terminals 2: The terminal operation feasibility determining unit 12 enables operation of the display device 60 for only one of the multiple communication terminals present in the available area Ar. For example, the terminal operation feasibility determining unit 12 enables operation of the display device 60 for only the communication terminal that is detected first. Alternatively, the terminal operation feasibility determining unit 12 may enable operation of the display device 60 for only the communication terminal on which a specific operation (such as pressing a button or tapping) is first performed. Multi-terminal support 3: The terminal operability determining unit 12 determines whether or not to enable operation of the display device 60 for multiple communication terminals, depending on the functions of each communication terminal. For example, when a user U plays a game by displaying game content on the display device 60, the terminal operability determining unit 12 may enable operation of the display device 60 using a gaming controller 90 with dedicated functions corresponding to game operations, but may disable operation of the display device 60 using the communication terminal 50 and wireless headphones 91. Alternatively, the display device 60 may be enabled for only one of each of communication terminals with different functions or types. In the example of FIG. 9, the display device 60 can be operated using different types of communication terminals for one user, namely, one gaming controller 90, one wireless headphones 91, and one communication terminal 50 (e.g., a smartphone).

[0047] In the above embodiment, the communication terminal position recognition unit 11 recognized the position of the communication terminal 50 relative to the display device 60 based on the communication status between the communication terminal 50 and the communication unit 61 of the display device 60. In another embodiment, the communication terminal position recognition unit 11 may recognize the position of the communication terminal 50 relative to the display device 60 based on images captured by the front seat camera 70 and the rear seat camera 71. In this case, the communication terminal position recognition unit 11 recognizes the position of the communication terminal 50 relative to the passenger seat display device 60a by extracting an image portion of the communication terminal 50 present around the passenger seat display device 60a from the image captured by the front seat camera 70. Furthermore, the communication terminal position recognition unit 11 recognizes the position of the communication terminal 50 relative to the left rear seat display device 60b by extracting an image portion of the communication terminal 50 present around the left rear seat display device 60b from the image captured by the rear seat camera 71. In addition, the communication terminal position recognition unit 11 recognizes the position of the communication terminal 50 relative to the right rear seat display device 60c by extracting the image portion of the communication terminal 50 that is located around the right rear seat display device 60c from the image captured by the rear seat camera 71.

[0048] 2 is a schematic diagram showing the configurations of the terminal operation management device 3 and the vehicle 100 divided by main processing content to facilitate understanding of the present invention, but the configurations of the terminal operation management device 3 and the vehicle 100 may be divided by other categories. Furthermore, the processing of each component may be executed by one hardware unit or multiple hardware units. Furthermore, the processing of each component shown in FIG. 5 may be executed by one program or multiple programs.
