  Install an application program for bath water heater (hereinafter abbreviated as bath water heater app) on a waterproof portable information processing terminal already owned by the user, and use the portable information processing terminal as a remote controller for the bath water heater This eliminates the need for a dedicated remote controller and can reduce the introduction cost of the bath water heater.

  However, since many portable information processing terminals are equipped with a camera, it is desirable to take measures so that the camera is activated in the bathroom and the unseen figure is not taken against the user's will.

  For example, recent portable information processing terminals can start other application programs while running an active application program in the background, so that the user can use other hot water heater apps in the background as other applications. When the program is started, the application program causes the camera to operate, and there is a possibility that an unseen figure will be shot against the user's will.

  For example, there is a so-called mirror app that can display and enlarge your face. An application program that uses and operates the camera device of a portable information processing terminal, such as a mirror application, to check for acne while taking a bath or to enlarge and display the "eye" part to correct the contact gap. Is routinely used. However, many of these mirror apps are often accompanied by shooting with a timer function so that the back hair can be confirmed, for example. For this reason, when the portable information processing terminal is placed on the edge of the bathtub while the shooting timer is inadvertently activated, the lower body may be shot regardless of the intention of the person.

  Furthermore, when a malicious application program is installed, there is a risk that the bathing situation may be seen from the outside. This is because, when an application program for a bath water heater is activated, it is almost certainly bathing, and if a malicious application program is activated in accordance with this activation, it is almost certainly voyeurized. For this reason, an application program for a bath water heater is desired to have a function of eliminating the fear that such an unsightly picture is taken against the user's will.

  The present invention is an application program for causing the portable information processing terminal to function as a remote controller for a bath water heater, in which the camera device of the portable information processing terminal is installed in the bathroom by the user.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a configuration example of a bath water heater system 4 according to an embodiment of the present invention. The bath water heater system 4 includes a bath water heater 5 and a portable information processing terminal 10 such as a tablet terminal or a smartphone. The portable information processing terminal 10 is installed with an application program (abbreviated as a bath water heater app) for causing the portable information processing terminal 10 to function as a remote controller of the bath water heater 5.

  The bath water heater 5 has a function of heating the water supply and discharging it to a predetermined tap 3, a function of pouring (filling) the bathtub 2, and a function of chasing hot water in the bathtub 2.

  The bath water heater 5 and the portable information processing terminal 10 are connected by wireless communication by wireless LAN (Local Area Network) or short-range wireless communication, and exchange various information. For example, the gateway address of the water heater 5 (the LAN address of the wireless LAN router 6) and the gateway address of the bath water heater remote controller 10 are matched (the bath water heater 5 and the bath water heater remote controller 10 are connected to the home network). . Thereby, the bath water heater 5 and the bath water heater remote controller 10 communicate with each other through the wireless LAN via the wireless router 6.

  The portable information processing terminal 10 functions as a remote controller for the bath water heater 5 by using the bath water heater application. That is, the function which receives the instruction | indication regarding the driving | operation of the bath water heater 5 from a user, the function which displays the operating state of the bath water heater 5, etc. are fulfilled. For example, setting of hot water supply temperature, setting of bath temperature, reservation setting of time for automatic hot water filling in the bath, automatic operation of the bath (the function of pouring hot water into the bathtub 2 and keeping it at the set temperature of the bath), etc. Or receive information about these and error information.

  The portable information processing terminal 10 that functions as a remote controller for the bath water heater 5 transmits settings and instructions received from the user to the bath water heater 5. In addition, various information is received from the bath water heater 5 and displayed.

  FIG. 2 shows the configuration of the portable information processing terminal 10. The portable information processing terminal 10 includes a CPU (Central Processing Unit) 11 as a control unit that performs overall control of the operation of the portable information processing terminal 10. The CPU 11 includes a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a nonvolatile memory 14, an operation unit 15, a display unit 16, a communication unit 17, a posture detection unit 18, an audio output unit 19, and a camera (camera device). ) 21 etc. are connected.

  The ROM 12 stores various types of fixed data. The nonvolatile memory 14 is a rewritable memory that retains stored contents even when the power is turned off, and stores an OS (Operating System) program, various application programs including a bath water heater application, various setting contents, and the like. The

  When the CPU 11 executes the bath water heater application stored in the nonvolatile memory 14, the portable information processing terminal 10 functions as a remote controller for the bath water heater 5. The RAM 13 is used as a work memory for temporarily storing various data and a memory for temporarily storing display data when the CPU 11 executes an application program.

  The display unit 16 includes a liquid crystal display that can display arbitrary contents such as an operation screen and a setting screen. The operation unit 15 has a function of accepting various operations from the user. The operation unit 15 is provided on the screen of the display unit 16, and includes a touch panel 15a that detects a position pressed by a finger, a pen, or the like, and a small number of hard keys.

  The communication unit 17 fulfills a function of communicating with the bath water heater 5 and other external devices by wireless LAN or near field communication.

  The posture detection unit 18 detects the posture of the portable information processing terminal 10 using a gyro. The posture detection unit 18 detects whether the portable information processing terminal 10 is used in a portrait orientation or a landscape orientation.

  The audio output unit 19 includes an amplifier and a speaker, and converts an electric audio signal into a sound wave and outputs the sound wave.

  The camera device 21 is provided on the back surface of the portable information processing terminal 10 or on the back surface and the front surface.

  When an application program (more specifically, an instance (entity) of the application program) requests exclusive use rights of the camera device 21 from the OS and uses the camera device 21, the application program can acquire the exclusive use right. The camera device 21 can be used. When ending use of the camera, the application program notifies the OS of the release of the camera (return of exclusive use right). When there are a plurality of camera devices 21, exclusive use rights are managed individually for each camera device 21. The exclusive use right of the camera is managed using, for example, a semaphore.

  Next, operation | movement of the portable information processing terminal 10 which operated the bath water heater application is demonstrated.

  The bath water heater app determines whether or not the portable information processing terminal 10 in which the bath water heater app is operating is used in the bathroom, and if it is determined that the portable information processing terminal 10 is used in the bathroom, Acquire exclusive use rights. After that, the exclusive use right of the camera device 21 is continuously captured even when the bath water heater application is in the background.

  Usually, the application program releases the exclusive use right of the camera device 21 acquired during operation in the foreground when the application program shifts to the background. As a result, the camera device 21 can be subsequently used by another application program operating in the foreground.

  On the other hand, the bath water heater app continues to capture the exclusive use right of the camera device 21 even when the bath water heater app is in the background (the camera device in “AndroidManifest.xml” in the root directory of the application). Do not use, but set access rights to use the camera device).

  The bath water heater application acquires the exclusive right to use the camera device 21, but does not use the camera device 21. Further, by continuing to capture the exclusive use right of the camera device 21, the use of the camera device 21 by another application program is prevented. Thereby, when the portable information processing terminal 10 is used in a bathroom as a remote controller for a bath water heater, the camera device 21 operates erroneously or operates maliciously, and the unrequited appearance is intended by the user. On the other hand, it is possible to prevent photographing.

  The bath water heater app determines that the portable information processing terminal 10 is being used in the bathroom when the bath water heater app is in operation and the portable information processing terminal 10 is in a landscape orientation (orientation). The reason is as follows.

  In addition, it may be only when the bath water heater app is in the foreground, or may include a period in the background. That is, when the bath water heater app is in the foreground and the portable information processing terminal 10 is in a landscape orientation, it is determined that the portable information processing terminal 10 is in the bathroom and the exclusive use right of the camera device 21 is acquired. Or, regardless of whether the bath water heater app is in the foreground or the background, the portable information processing terminal 10 is portable when the portable information processing terminal 10 is in a landscape orientation while the bath water heater app is running. The exclusive information processing terminal 10 may be determined to be in the bathroom and the exclusive use right of the camera device 21 may be acquired.

  The remote controller of the bath water heater 5 is used not only in a bathroom but also in a kitchen, for example. When the user uses the portable information processing terminal 10 as a remote controller for the bath water heater 5 in the bathroom, the portable information processing terminal 10 is held in the hand while the operation such as changing the set temperature is performed, but is not operated. In some cases, the portable information processing terminal 10 is stood and used somewhere. In particular, while bathing in a bathtub, it is used by standing against the edge of the bathtub, or a part of the bathtub is closed with a lid, and the portable information processing terminal 10 is placed on the lid for use.

  The floor area that can be allocated to a bathroom is narrow due to housing circumstances, and the edge of the bathtub is narrowed in the narrow bathroom in order to increase the capacity of the bathtub as much as possible. Therefore, when the portable information processing terminal 10 is stood and used in a portrait orientation on the edge of the bathtub, there is a possibility that the portable information processing terminal 10 slips from the edge of the bathtub and is submerged compared to the case of leaning in the landscape orientation. high.

  Further, when the portable information processing terminal 10 is placed on the lid of the bathtub and used, there is a high possibility that a leg or the like is hooked on the lid, and at that time, the portable information processing terminal 10 placed on the lid is used. Will be submerged in the bathtub.

  Even if it is said to be waterproof, the waterproof performance of the portable information processing terminal 10 is not so high, so if it falls into a deep bathtub and is submerged, it will be submerged. Therefore, many users use the portable information processing terminal 10 brought into the bathroom in a landscape orientation, leaning against the edge of the bathtub.

  Therefore, in the bath water heater app according to the present embodiment, the portable information processing terminal 10 is used in a bathroom when the portable information processing terminal 10 in which the bath water heater app is operating is in a landscape orientation. The exclusive use right of the camera device 21 is acquired and captured. If there are a plurality of camera devices 21, exclusive use rights are acquired and captured for all of them.

  In addition, for example, when the portable information processing terminal 10 in which the bath water heater application is operating is in a landscape orientation, whether or not the portable information processing terminal 10 is used in the bathroom, or the camera device 21 is used. It asks the user whether or not to prohibit, and when it receives a reply that it is used in the bathroom or the camera device 21 is prohibited, it operates to acquire the exclusive right to use the camera device 21. Also good.

  Further, when the bath water heater application tries to acquire the exclusive use right of the camera device 21, another application program has already acquired the exclusive use right of the camera device 21, and the exclusive use of the camera device 21 is obtained. If the right cannot be acquired, whether or not the bath water heater app is forcibly terminated, or the exclusive use right of the camera device 21 cannot be acquired (that is, the use of the camera device 21 cannot be prohibited). When the user approves, the operation of the bath water heater app is continued, and when not approved, the bath water heater app is forcibly terminated.

  The bath water heater application does not immediately release the acquired exclusive use right even if the portable information processing terminal 10 is placed in a vertically long posture (orientation). When starting another application, such as when using the portable information processing terminal 10 for the Internet, the user operates the portable information processing terminal 10 while holding it in a portrait orientation. For this reason, when the exclusive use right of the camera device 21 is released immediately when the camera device 21 is in the portrait orientation, other applications are exclusive of the camera device 21 even though the portable information processing terminal 10 is in the bathroom. There is a risk of obtaining usage rights.

  Therefore, the bath water heater app does not immediately release the exclusive use right of the camera device 21 even if the portable information processing terminal 10 is placed in a vertically long posture while the exclusive use right of the camera device 21 is captured. The bath water heater app is set in the foreground, and the user is inquired whether or not the exclusive use right of the camera device 21 may be released. If the release permission is not received, the camera device 21 is continuously captured. When the release permission is received, the exclusive use right of the camera device 21 is released.

  For example, the mirror app is overwhelmingly used in a vertically long posture. This is because the human face is vertically long, and the portable information processing terminal is held with one hand while the other hand is required to touch the mole, hair, and contact lens. Is done. If the mirror app starts before the bath water heater app asks whether the exclusive use right of the camera device 21 may be released, the mirror app fails to connect the camera device. Although a connection failure message is displayed, an inquiry as to whether or not the exclusive use right of the camera device 21 may be released from the bath water heater app is made immediately thereafter. Can prevent misunderstanding.

  Even when the set temperature of the bath or the hot water supply temperature (shower temperature) is changed, the user operates the portable information processing terminal 10 in the portrait orientation and holds it in his / her hand. If the operation for the bath water heater app is changed within a certain time (for example, 3 seconds) from the first time, or if the bath water heater app is changed from the background to the foreground, the above inquiry is not performed and the camera device 21 Continue to capture. When the portable information processing terminal 10 does not receive an operation on the bath water heater app even after a certain period of time has elapsed since the portable information processing terminal 10 is in the portrait orientation, the above-described inquiry is performed. Thus, an inquiry is made only when necessary, and the operability is improved.

  The bath water heater application also allows the user to use the exclusive use right of the camera device 21 even when another application requests the exclusive use right of the camera device 21 while the exclusive use right of the camera device 21 is captured. The camera device 21 continues to be captured if the release permission is not received, and the exclusive use right of the camera device 21 is released if the release permission is received.

  For example, the above-described inquiry is performed when another application started when the bath water heater application is in the background requests the exclusive use right of the camera device 21.

  When the user's permission is received, the use of the camera device 21 by another application is not contrary to the intention of the user, and there is no problem even if another application program is operated while the camera device 21 is used. .

  In addition, the bath water heater app checks whether or not the exclusive use right of the camera device 21 has been captured when the bath water heater app is terminated. Release public use rights.

  FIG. 3 is a flowchart showing a schematic processing procedure of the bath water heater application. The bath water heater application alternately performs processing as a remote controller of the bath water heater 5 and processing regarding acquisition / release of the exclusive use right of the camera device 21. First, processing for one unit as a remote controller of the bath water heater 5 is executed (step S101). For example, operation detection or display update is performed.

  Next, it is determined whether or not the bath water heater app is capturing the exclusive use right of the camera device 21, and if the exclusive use right of the camera device 21 is not captured (step S102; No), the camera device The camera acquisition monitoring process for acquiring the exclusive use right of the camera device 21 is performed according to the determination of whether to acquire the exclusive use right of 21 and the result of the determination (step S103), and the process proceeds to step S105 To do.

  When the exclusive use right of the camera device 21 is captured (step S102; Yes), it is determined whether or not the exclusive use right of the camera device 21 is to be released, and the camera device 21 is in accordance with the result of the determination. A camera release monitoring process for releasing the exclusive use right is performed (step S104), and the process proceeds to step S105.

  In step S105, it is determined whether an instruction to end the bath water heater application or a forced end instruction to be described later has been received. If neither an end instruction nor a forced end instruction has been received (step S105; No), the process returns to step S101 and continues.

  If an end instruction or a forced end instruction is received (step S105; Yes), it is checked whether or not the bath water heater app has captured the exclusive use right of the camera device 21 (step S106). When the exclusive use right of the camera device 21 is not captured (step S106; No), the bath water heater application is terminated, and when the exclusive use right of the camera device 21 is captured (step S106; Yes) After releasing the exclusive use right of the camera device 21 (step S107), the bath water heater application is terminated.

  FIG. 4 is a flowchart showing details of the camera acquisition monitoring process (step S103 in FIG. 3). It is determined whether or not the portable information processing terminal 10 has changed to a landscape orientation (step S201). When the posture does not change to the landscape orientation (step S201; No), this processing ends (return).

  When the posture is changed to the landscape orientation (step S201; Yes), the OS is requested to acquire the exclusive use right of the camera device 21 (step S202). If acquisition of the exclusive use right of the camera device 21 has failed (step S203; No), a predetermined warning is displayed, and a forced termination instruction of the bath water heater app is returned as a return value (step S204). Is terminated (return).

  For example, “Because another application program is using the camera device 21, the bath water heater application is forcibly terminated.” “After terminating other application programs that are using the camera device 21, again, Please start the bath water heater app. "

  Note that if the user approves the use of the camera device 21 by another application program by inquiring the user whether or not the other application program may remain in the state of using the camera device 21, The operation of the bath water heater app may be continued without obtaining the exclusive use right, and the bath water heater app may be forcibly terminated if the user does not approve the use of the camera device 21 by another application program. .

  When acquisition of the exclusive use right of the camera device 21 is successful (step S203; Yes), the capture of the exclusive use right of the camera device 21 is continued even when the bath water heater app is in the background. (Step S205), the process ends (return). Specifically, when shifting to the background, the release of the exclusive use right of the camera device 21 is not notified to the OS.

  FIG. 5 is a flowchart showing details of the camera release monitoring process (step S104 in FIG. 3). It is determined whether or not the portable information processing terminal 10 has changed to a vertically long posture (step S301). When the portable information processing terminal 10 changes to a vertically long posture (step S301; Yes), the user is inquired whether to release the exclusive use right of the camera device 21 (step S303).

  Here, if the user receives an operation on the bath water heater app from when the user changes to a vertically long posture until a predetermined time elapses, the process ends, and if no operation is received, the above inquiry is made. I do. For example, a message such as “Currently prohibiting the use of the camera. Do you want to cancel the prohibition of the use of the camera” and a selection button for canceling / not canceling are displayed, and an operation on the selection button is received.

  When receiving a reply from the user to release the exclusive use right of the camera device 21 (step S304; Yes), the exclusive use right of the camera device 21 is released (step S305), and this process ends. (return).

  If the reply to release the exclusive use right of the camera device 21 is not received (step S304; No), this process is terminated without releasing the exclusive use right of the camera device 21 (return).

  If the posture has not changed to the vertically long posture (step S301; No), it is checked whether another application program requests the exclusive use right of the camera device 21 (step S302).

  If another application program requests the exclusive use right of the camera device 21 (step S302; Yes), the process proceeds to step S303. If another application program does not request the exclusive use right of the camera device 21 (step S302; No), this process is terminated (return).

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are also included in the present invention.

  In the embodiment, it is determined that the portable information processing terminal 10 is in the bathroom when the portable information processing terminal 10 is in the landscape orientation while the bath water heater application is in operation. It is not limited to. For example, a bathroom in-use button may be provided, and when this button is selected, it may be determined that the portable information processing terminal 10 is being used in the bathroom. Moreover, you may determine whether the portable information processing terminal 10 exists in a bathroom by analyzing the image which the camera device 21 image | photographed. In this case, the camera device 21 is used only for this determination and not used for others.

  Further, whether or not the bath is in automatic operation may be further added to the determination element. For example, it may be determined that the portable information processing terminal 10 is in the bathroom when the bath water heater application is in operation, the bath is in automatic operation, and the portable information processing terminal 10 is in a landscape orientation. . Further, the exclusive use right of the camera device 21 being captured may be released when the automatic bath operation is turned off.
