However, the present invention is not limited to the following embodiments as long as the technical idea is included.

[1] Operation Control Device Next, the configuration of the operation control device 1 of the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram illustrating an example of the configuration of the operation control device 1 according to the present embodiment, and FIG. 2 is a diagram illustrating an arrangement example of electrodes provided in the information acquisition unit 11 according to the present embodiment.

  The operation control device 1 of the present embodiment is a control device that operates in conjunction with a remote control device such as an electronic device or an electric tool, an operation unit of a machine for a work such as a production line, a steering wheel of a car or a heavy machine, or another operation operation unit. Used as

  And the operation control apparatus 1 makes an electrode contact the different site | parts joined to the trunk | drum which has a heart, such as an index finger, a middle finger, a ring finger, etc. of an operator's both hands, for example, and is exposed as skin. Obtained biometric information (specifically, heart activity information indicating whether or not the heart is active) related to the movement of the operator's heart, and accepted the biometric information if received. It has a configuration in which an operator's input operation is validated and operation control for a controlled device (not shown) is executed.

  With this configuration, in the operation control device 1 according to the present embodiment, when biometric information is not acquired, the input operation of the operator is invalidated and the biometric information is acquired. The operator's input operation can be validated.

  For this reason, in the operation control apparatus 1 of this embodiment, since it can be determined whether it is an input operation which the operator intended by presence or absence of biometric information, it is possible for the operator's intentional and appropriate operation. On the other hand, the controlled device can be operated and controlled accurately.

  Therefore, the operation control device 1 according to the present embodiment can prevent an input operation from being accepted when the operator does not intend, and can reliably prevent a malfunction in the controlled device caused by an operation not intended by the operator. Be able to.

  Specifically, as illustrated in FIG. 1, the operation control device 1 of the present embodiment includes an I / O interface 10, an information acquisition unit 11 that acquires cardiac activity information of an operator, a ROM / RAM 12, and a display Unit 13, display control unit 14 that controls image display on display unit 13, operation unit 15, recording device 16 in which control data and the like are recorded, management control unit 17, and control of an operator's input operation and An operation control unit 18 that performs management, and the above-described units are connected to each other by a bus 19.

  For example, the information acquisition unit 11 of the present embodiment constitutes an acquisition unit of the present invention, and the operation control unit 18 constitutes a reception unit of the present invention. Further, for example, the display unit 13 of the present embodiment constitutes a display unit of the present invention.

  The I / O interface 10 is a short-range wireless such as a wired interface such as USB (Universal Serial Bus), an infrared interface such as IrDA, Bluetooth (registered trademark), a wireless LAN (IEEE208.11a, b, n, ac). Various data are exchanged between the bus 19 and a controlled device such as an air conditioner, which is an interface and is a controlled device.

  In particular, the I / O interface 10 is based on control data for controlling the controlled device generated by the operation control unit 18, as will be described later, in order to execute an operation corresponding to the operation content in the controlled device. The signal generated in this manner (hereinafter also referred to as “control signal”) is transmitted.

  Further, the I / O interface 10 is connected to, for example, two electrodes A111a and B111b provided in a case in the operation control apparatus 1 and provided in a portion that can be contacted by an operator.

  The I / O interface 10 acquires the potential between both hands of the operator and provides it to the information acquisition unit 11 when the operator brings a part of each hand into contact with the electrode A 111a and the electrode B 111b.

  For example, as shown in FIG. 2, the electrode A 111 a and the electrode B 111 b are exposed on the back surface of the operation control device 1, and when the operation control device 1 is held with both hands, a predetermined finger such as a middle finger in each human hand is used. It is provided so that it can contact with a finger.

  The information acquisition unit 11 acquires a potential between both hands of the operator when the operator makes a part of each of the hands (for example, fingers in each hand) contact the electrode A 111a and the electrode B 111b, and The potential difference is measured.

  Then, the information acquiring unit 11 sandwiches the heart from the bipolar potential (I-induced by the potential of the right hand (−) and the left hand (+), or the part joined to the torso, based on the acquired potential or the measured potential difference, Change of action potential in the heart of the operator based on the limb guidance that shows the state of electricity on the plane seen from the front), and detect the heart activity information (ie biometric information) obtained with the movement of the heart get.

  In the present embodiment, the information acquisition unit 11 calculates the measured change state of the potential difference as an action potential and graphs the electrocardiogram obtained by graphing the change state of the action potential along the time axis. It may be acquired as activity information.

  The display unit 13 is configured by a panel of a liquid crystal element or an organic EL (Electro Luminescence) element, for example, and displays predetermined information, for example, information related to an operation, based on display data generated by the display control unit 14.

  The display control unit 14 generates drawing data for displaying an image on the display unit 13 in conjunction with the management control unit 17 and the operation control unit 18, and causes the display unit 13 to display the generated drawing data.

  In particular, when the operation unit 15 is configured by a touch panel, the display control unit 14 operates in conjunction with the management control unit 17 and the operation control unit 18 and performs various operations on the display unit 13 according to the coordinates on the touch panel. A button (icon) corresponding to is displayed.

  Further, in this case, the display control unit 14 displays the operation buttons on the display unit 13 so as to be operable by the operator when the heart activity information is acquired, and when the heart activity information is not acquired. Causes the operation buttons to be displayed on the display unit 13 in an inoperable manner.

  The operation unit 15 includes a keypad having operation buttons corresponding to various operations, a numeric keypad, or a touch panel formed on the display surface of the display unit 13, and controls operation signals according to an input operation by the operator. Supply to unit 18.

  In particular, when the operation unit 15 is configured by a touch panel, the operation unit 15 receives an input operation of an operator based on an operation image displayed on the display unit 13.

  The recording device 16 is composed of an EEPROM (Electrically Erasable Programmable Read Only Memory), a NAND type, a NOR type, or other non-volatile memory, and the operation control device 1 is used to operate the controlled device in the recording area. An application recording unit 161 that records an application (hereinafter referred to as “operation application”) and a control data recording unit 162 that records control data are provided.

  In the control data recording unit 162, each function of the controlled device controlled using the operation control device 1 and control data corresponding to the operation in the operation unit 15 (displayed on the display unit 13 when the operation unit 15 is a touch panel) are displayed. Including the data of the icon to be displayed) in association with each other.

  The management control unit 17 is mainly configured by a CPU (Central Processing Unit), and integrally controls each unit of the operation control device 1.

  The operation control unit 18 is configured by an independent CPU or a CPU that is common to the management control unit 17, and executes an operation application under the control of the management control unit 17, thereby causing the information analysis unit 181 and the operation control unit to operate. 182 and the signal generation unit 183 are realized.

  Based on the heart activity information acquired by the information acquisition unit 11, the information analysis unit 181 determines whether or not both hands of the operator are in contact with the electrode A111a and the electrode B111b.

  The operation control unit 182 enables the operator's input operation to the operation unit 15 when the information analysis unit 181 determines that both hands of the operator are in contact with the electrodes A111a and B111b, When it is determined that both hands of the operator are not in contact with the electrodes A111a and B111b, the operator's input operation to the operation unit 15 is invalidated.

  For example, when the operation unit 15 is a touch panel and the operation control unit 182 determines that both hands of the operator are in contact with the electrode A111a and the electrode B111b, the operation button is displayed on the display unit 13. When the touch operation is performed on the operation button, an input operation corresponding to the touch operation is received.

  On the other hand, when it is determined that the operator's hands are not in contact with the electrode A111a and the electrode B111b, the operation control unit 182 displays the operation button on the display unit 13 so that the touch operation is disabled, and the operation button Even if the touch operation is executed, the acceptance of the input of the operation corresponding to the touch operation is invalidated.

  In addition, for example, when the operation unit 15 is a push-down switch and the operation control unit 182 determines that both hands of the operator are in contact with the electrode A 111a and the electrode B 111b, When the push-down operation is executed, an input operation corresponding to the push-down operation is accepted.

  On the other hand, when it is determined that the operator's hands are not in contact with the electrode A111a and the electrode B111b, the operation control unit 182 corresponds to the touch operation even if the push-down operation is performed. Disable acceptance of operation input.

  Further, for example, when the operation unit 15 is a lever, a handle, or a push-down switch, and the operation control unit 182 determines that the operator's both hands are in contact with the electrode A111a and the electrode B111b, the above operation is performed. When it is determined that the operation of the unit 15 can be performed (ie, unlocked) and the operator's hands are not in contact with the electrode A 111a and the electrode B 111b, the operation of the operation unit 15 is performed. In an incapable state (ie, the lever or handle does not move or the switch cannot be pushed down (locked state)), the acceptance of input to the operation unit 15 is invalidated.

  When it is determined that the operator's input operation to the operation unit 15 is valid, the signal generation unit 183 generates control data corresponding to the operation input to the operation unit 15 or a control signal indicating the control data. The control data generated or the control signal indicating the control data is transmitted to the controlled device to be controlled via the / O interface 10.

[2] Operation of Operation Control Device Next, the operation of the operation control device 1 of the present embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing an operation executed in the operation control device 1 of the present embodiment.

  In this operation, it is assumed that control data corresponding to the controlled device is already recorded in the control data recording unit 162, and the operation control unit 182 is in a state where an input operation to the operation unit 15 cannot be detected. Shall.

  First, the information analysis unit 181 detects (determines) that the operator's hands are in contact with the electrode A111a and the electrode B111b based on the heart activity information supplied from the information acquisition unit 11 (step S1). The operation control unit 182 waits for a predetermined input operation on the operation unit 15 (step S2).

  In particular, in the process of step S2, the operation control unit 182 operates in conjunction with the display control unit 14 to validate the input of the operation button displayed on the display unit 13 when the operation unit 15 is a touch panel. To display. Further, when the operation unit 15 is in a locked state in which the operation unit 15 is physically locked, the operation control unit 182 shifts to a lock release state in which the lock is released.

  Next, the operation control unit 182 determines whether or not a predetermined input operation on the operation unit 15 is detected during a predetermined period (for example, 2 seconds) (step S3).

  At this time, if the operation control unit 182 does not determine that the input operation has been detected during the predetermined period, for example, a display for invalidating the input of the operation button displayed on the display unit 13 is displayed. Alternatively, the operation control unit 182 shifts to an inoperable state such as shifting to a locked state in which the operation unit 15 is physically locked (step S4), and shifts to the process of step S1.

  On the other hand, if the operation control unit 182 determines that the input operation has been detected during a predetermined period, the operation control unit 182 causes the signal generation unit 183 to generate a control signal corresponding to the input operation input by the operation unit 15 ( Step S5).

  Next, the signal generation unit 183 causes the control signal generated via the I / O interface 10 to be transmitted to the controlled device (step S6) and ends the operation.

  Instead of the above, when the operation control unit 182 detects an input operation in the operation 15, based on the heart activity information supplied from the information acquisition unit 11, both hands of the operator are applied to the electrode A 111 a and the electrode B 111 b. The contact may be detected (determined) to determine the effectiveness of the input operation.

  As described above, the operation control apparatus 1 according to the present embodiment invalidates the operator's input operation when the biometric information is not acquired, and also acquires the biometric information. Can enable the input operation of the operator.

  Therefore, the operation control apparatus 1 of the present embodiment can determine whether or not the input operation is intended by the operator based on the presence or absence of biometric information. The controlled device can be operated and controlled accurately.

  As a result, the operation control apparatus 1 according to the present embodiment can prevent an input operation from being accepted when the operator does not intend, and can reliably prevent a malfunction in the controlled apparatus caused by an operation not intended by the operator. can do.

  Note that the operation control device 1 of the present embodiment may function as a control device dedicated to the controlled device, and for example, install a predetermined application in a communication terminal device such as a smartphone or a tablet-type information communication terminal device. Thus, the same function, operation and effect may be realized.

  Further, the operation control device 1 of the present embodiment may perform operation control on a plurality of controlled devices to be controlled. In this case, control data corresponding to each controlled device is stored in the ROM / RAM 12, the control data of the controlled device selected by the operator is set in the control data recording unit 162, and controlled using an application. Execute device operation control.

[3] Modified Example Next, a modified example of the operation control device 1 of the present embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram for explaining a modified example (modified example 1) in the operation control apparatus 1 of the present embodiment, and describes a modified example (modified example 2) of the operation control apparatus 1 of the present embodiment. FIG.

[3.1] Modification 1
In the above embodiment, the operation control device 1 is provided separately from the controlled device. However, the controlled device may have an input control module that realizes the same function as the configuration of FIG. Good.

  In this case, the electrode A111a and the electrode B111b may be provided in the casing of the controlled device. For example, when an electrode A111a and an electrode B111b are provided on the side surface of an electric device such as an electric pot, and the little finger of the operator's both hands is in contact with the electrode A111a and the electrode B111b, it is effective to accept an input operation for a button such as hot water supply For example, it is possible to prevent erroneous operation and improve its safety.

  Instead of electrical equipment, an input control module having the same function as that shown in FIG. 1 may be provided in the operation unit of the controlled device in a machine such as a heavy machine, a power tool, an industrial machine robot, or an automobile. Good.

  In this case, for example, as shown in FIG. 4, the electrode A 111 a and the electrode B 111 b are arranged on the right operation lever 200 and the left operation lever 210 as the operation unit of the controlled device, and are structurally integrated with the operation unit. It is formed.

  In this case, the input operation is invalidated unless the operator touches the operation lever with both hands. Further, instead of the operation lever, the electrode A111a and the electrode B111b may be arranged on the handle or the operation button so that the input operation is invalidated unless the operator touches the handle or the operation button with both hands.

  By having such a configuration, for example, even when an operator's clothes are caught on a lever or button and an operation unintended by the operator is performed, the input operation is invalidated, and various devices and machines, etc. The safety at the time of operating the apparatus can be improved.

  Also, when operating a power tool such as a chainsaw or electric saw, it is possible to invalidate the operation with one hand, so even when using a machine that has a high risk of being damaged by these malfunctions. , Its safety can be improved.

  In this case, when the input operation is invalid, the lever and the button may be physically locked. When the input operation is valid, the lock is released to validate the input operation. It may be.

[3.2] Modification 2
In the above embodiment, a configuration is adopted in which the input operation is switched between valid and invalid based on the heart activity information of the operator. There is a case. For example, when the operator is under an extreme stress state, the operator may perform an erroneous operation.

  Therefore, in this modification, in order to prevent such an erroneous operation, the stress state of the operator is detected as biometric information together with the cardiac activity information, and when the stress state has a predetermined condition, The input operation by the operator may be validated and the input operation may be invalidated when the condition is not satisfied.

  Specifically, in this modified example, the operator's stress state is detected based on the heart activity information to detect whether or not the heartbeat interval of the operator performing the operation has a predetermined condition, When the heartbeat interval satisfies a predetermined condition, the input operation by the operator is validated.

  Usually, as illustrated in FIG. 5, the appearance period T of the R wave on the operator's electrocardiogram (T1-T7 in FIG. 5) is constant, but this appearance period T depends on the stress level of the operator. Change. In particular, in general, when the stress is weak, the appearance period T becomes long, whereas when the stress is strong, the appearance period T becomes short.

  Therefore, in this modification, when the R wave appearance period T is calculated from the electrocardiogram of the operator and the average value is equal to or greater than a predetermined threshold (that is, when the stress level is equal to or less than a predetermined value). ) Has a configuration that validates the operator's input operation on the assumption that a predetermined condition is satisfied.

  By having such a configuration, it is possible to invalidate input operations in various devices when the operator is under extreme stress and improve safety when operating the various devices. It has become.

  In order to measure the appearance period T, it is necessary to acquire and analyze an electrocardiogram for several seconds. Basically, a predetermined time is required until a stress state is detected. However, when the stress state is detected in a short time, only one of the appearance periods T may be compared with the threshold value to determine the operator's stress state. The operator's stress state may be determined by acquiring the electrocardiogram in advance and comparing the electrocardiogram during normal operation with that during operation.

  In addition, this determination may be performed by the signal generation unit 183. In this case, the signal generation unit 183 constitutes, for example, the detection means of the present invention.

[3.3] Modification 3
The present embodiment and the above-described heart activity information or information indicating the stress state detected thereby are used as biometric information. However, it is accompanied by heart motion such as simple heartbeat information, blood pressure information, or body temperature information. Vital signs may be used as biometric information.

  In such a case, the blood pressure and heart rate information is detected from both hands, and it is detected that the operator is intentionally operating such as when they match.

[3.4] Modification 4
The electrode A 111 a and the electrode B 111 b according to the present embodiment are provided in the case of the operation control device 1 or the case of the controlled device, but are connected to the I / O interface 10 and include the electrode A and the electrode B. You may implement | achieve by the module formed separately from the control apparatus 1 and a to-be-controlled device.

  In this case, for example, the electrode A 111 a and the electrode B 111 b are formed as a sheet-like module, and are realized by being attached to the rear surface of the casing of the operation control device 1 or the periphery of the operation unit of the controlled device.
