Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the above-described conventional switch device has the following problems. That is, in the switch device disclosed in the above publication, when the user operates the operation unit while gripping the ring part, a protruding part that protrudes from the surface of the spoke part so that the palm side of the operating finger comes into contact is provided, so that erroneous operation by the user can be suppressed. However, with such a configuration, for example, it cannot be applied to operations on a touch panel such as a navigation system of an automobile. Therefore, it has been difficult to detect an erroneous operation on an operation button of various devices mounted on a moving body such as an automobile.

[0006] An object of the present invention is to provide an erroneous operation detection device, an erroneous operation suppression device, an erroneous operation detection method, an erroneous operation suppression method, an erroneous operation detection program, and an erroneous operation suppression program that can detect an erroneous operation when operating an operation button of various devices mounted on a moving body where vibration and shock occur, and take appropriate measures.

Means for Solving the Problems

[0007] An erroneous operation detection device according to a first invention is an erroneous operation detection device that detects an erroneous operation of an input to various operation buttons in a moving body, and includes an operation reception unit, a detection unit, and an erroneous operation determination unit. The operation reception unit receives an operation on the operation button. The detection unit detects vibration and shock in the moving body. The erroneous operation determination unit determines whether it is an erroneous operation when the operation reception unit receives an operation on the operation button when the detection unit detects vibration or shock.

[0008] Here, for example, it is a device that detects an erroneous operation of an input when operating an operation button of various devices mounted on a moving body such as an automobile where vibration and shock are likely to occur, and determines that it is an erroneous operation if there is an input operation on the operation button at the timing when vibration or shock is detected. Here, the moving body includes, for example, automobiles (including electric vehicles and hybrid vehicles), buses, railways, trucks, ships, airplanes, helicopters, drones, and various attractions installed in facilities such as amusement parks.

[0009] The operation buttons include, for example, operation buttons for car navigation, audio, air conditioner, driving assistance systems, smartphones, tablet terminals, etc. mounted on automobiles, as well as touch panel buttons, etc. The determination of an incorrect operation is performed, for example, according to the direction of vibration or impact applied to the operation direction of the operation button.

[0010] The users who operate the operation buttons include, for example, drivers of automobiles, buses, railways, trucks, etc., passengers, as well as pilots and passengers of airplanes, ships, etc. Thereby, when the operation button is operated at the timing when vibration or impact is applied to a moving body such as an automobile, it is possible to determine whether or not the operation is an incorrect operation. As a result, it is possible to detect an incorrect operation when operating the operation buttons of various devices mounted on a moving body where vibration or impact occurs, and to take appropriate measures.

[0011] The incorrect operation detection device according to the second invention is the incorrect operation detection device according to the first invention. When the detection unit detects vibration or impact in the direction opposite to the operation direction of the operation button, and the operation reception unit receives the operation of the operation button, the incorrect operation determination unit determines that the operation is an incorrect operation. Thereby, in a moving body such as an automobile, when vibration or impact in the direction opposite to the operation direction of the operation button is detected, it is assumed that the user accidentally touched the operation button as a result of vibration or the like being applied while the finger was separated from the operation button. Therefore, in this case, it can be determined that the operation is an unintended operation for the user and is determined as an incorrect operation.

[0012] The incorrect operation detection device according to the third invention is the incorrect operation detection device according to the second invention. When the detection unit detects vibration or impact in the direction opposite to the operation direction of the operation button, the detection unit detects the acceleration of the vibration or impact. When the moving speed or moving distance corresponding to the acceleration is equal to or greater than a predetermined value, the incorrect operation determination unit determines that it is an incorrect operation of operating an operation button different from the operation button that was being operated. Accordingly, when the moving speed and moving distance calculated from the acceleration of vibration or impact are equal to or greater than a predetermined value and the operation button is operated, by determining it as an incorrect operation, it is possible to avoid determining that all cases of receiving small vibrations or impacts are incorrect operations.

[0013] The incorrect operation detection device according to the fourth invention is the incorrect operation detection device according to the first invention. When the detection unit detects vibration or impact in a direction opposite to the operation direction of the operation button and perpendicular to the operation direction, and the operation reception unit receives the operation of the operation button, the incorrect operation determination unit determines that it is an incorrect operation of operating an operation button different from the operation button that was being operated. Accordingly, in a moving body such as an automobile, when vibration or impact including a component in a direction opposite to the operation direction of the operation button and a component perpendicular thereto is detected, it is assumed that as a result of vibration or the like being applied while the user's finger is separated from the operation button, the user accidentally touches a different operation button. Therefore, in this case, it can be determined that the operation is an unintended operation by the user and is determined as an incorrect operation.

[0014] The incorrect operation detection device according to the fifth invention is the incorrect operation detection device according to the second or fourth invention. When the incorrect operation determination unit determines that it is an incorrect operation, it invalidates the operation. Accordingly, for example, when it is determined as an incorrect operation in the above-described incorrect operation determination, by invalidating the operation, it is possible to prevent an incorrect operation by the user from being accepted.

[0015] The incorrect operation detection device according to the sixth invention is the incorrect operation detection device according to the first or second invention, and further includes an environmental sound detection unit that detects environmental sound outside the moving body. Accordingly, by detecting environmental sound including the traveling sound of the moving body, etc., it is possible to perform output control according to the magnitude and type of the external environmental sound.

[0016] The malfunction detection device according to the seventh invention is the malfunction detection device according to the first or second invention. When the operation reception unit receives an operation on the operation button from the user, the output control unit controls the output unit to output a predetermined operation sound, and when the malfunction determination unit determines that it is a malfunction, the output control unit controls the output unit to output a warning sound different from the predetermined operation sound. The output unit is, for example, a speaker, and emits a warning sound to be output when it is determined that there is a malfunction, in addition to the operation sound of the operation button. Accordingly, when it is determined that it is a malfunction, by causing the output unit to output a warning sound different from the normal operation sound, the user can be notified of the malfunction.

[0017] The malfunction detection device according to the eighth invention is the malfunction detection device according to the seventh invention, further comprising an environmental sound detection unit that detects the environmental sound outside the moving body, and the output control unit controls the output unit to output a sound wave that cancels the environmental sound according to the environmental sound detected by the environmental sound detection unit. Accordingly, by causing the output control unit to output a sound wave that cancels the environmental sound from the output unit, it is possible to control so that the user can easily hear the above-described operation sound, warning sound, etc.

[0018] The malfunction detection device according to the ninth invention is the malfunction detection device according to the first or second invention, further comprising a finger proximity detection unit that detects the proximity of a finger to the operation button. Accordingly, since it is possible to detect that the finger is close to the operation button within a predetermined distance or less, the proximity of the finger can be set as one of the conditions in the above-described malfunction determination.

[0019] The malfunction detection device according to the tenth invention is the malfunction detection device according to the ninth invention. When the detection unit detects vibration or impact in a direction opposite to the operation direction of the operation button in a state where the finger proximity detection unit detects the proximity of the finger, even when the operation reception unit receives an operation on the operation button, the malfunction determination unit determines that the operation is a malfunction. In this way, when vibration or impact in the direction opposite to the operation direction of the operation button is applied in a state where it is detected that the finger is close to the operation button within a predetermined distance or less, by detecting that the operation is an erroneous operation, the detection accuracy of the erroneous operation can be improved.

[0020] The erroneous operation detection device according to the 11th invention is the erroneous operation detection device according to the 7th invention, further including a finger proximity detection unit that detects the proximity of a finger to the operation button. When the finger proximity detection unit detects that the finger has approached within a predetermined distance or less, the output control unit outputs a sound indicating the proximity of the finger. In this way, it is possible to notify the user by sound that the finger has approached within a predetermined distance from the operation button.

[0021] The erroneous operation detection device according to the 12th invention is the erroneous operation detection device according to the 11th invention, and the output control unit controls the output unit so as to output different sounds according to the type of the operation button detected by the finger proximity detection unit. In this way, by causing the output unit to output different sounds according to the type of the operation button to which the finger is close, it is possible to notify the user whether the operation button that the user is trying to operate is correct or not.

[0022] The erroneous operation detection device according to the 13th invention is the erroneous operation detection device according to the 1st or 2nd invention, and further includes a vibration generation unit that generates vibration in a part including the operation button when the erroneous operation determination unit determines that it is an erroneous operation. In this way, the user can recognize that the operation on the operation button when there is vibration or impact is an erroneous operation by the vibration generated in the part including the operation button.

[0023] The erroneous operation detection device according to the 14th invention is the erroneous operation detection device according to the 1st or 2nd invention, and the operation button is any one of a push button switch, a lever switch, a slide switch, a touch panel, and a proximity switch. In this way, it is possible to effectively detect erroneous operations on various operation buttons.

[0024] The misoperation prevention device according to the 15th invention is a misoperation prevention device that suppresses misoperations in input to various operation buttons on a touch panel in a moving body, and includes an operation reception unit, a detection unit, and a display control unit. The operation reception unit receives operations on the operation buttons. The detection unit detects vibrations and impacts in the moving body. When the detection unit detects vibrations or impacts including a component in a direction opposite to the operation direction of the operation button and perpendicular to the operation direction, and the operation reception unit receives an operation on the operation button, the display control unit moves and displays the position of the operation button on the touch panel according to the magnitude of the component in the perpendicular direction.

[0025] Here, for example, it is a device that suppresses misoperations in input when operating operation buttons of various devices mounted on a moving body such as an automobile where vibrations and impacts are likely to occur. When there is an input operation on the operation button at the timing when vibrations or impacts including a component in a direction opposite to the operation direction of the operation button and perpendicular to the operation direction are detected, the position of the operation button on the touch panel is moved and displayed according to the magnitude of the component in the perpendicular direction. Here, the moving body includes, for example, automobiles (including electric vehicles and hybrid vehicles), buses, railways, trucks, ships, airplanes, helicopters, drones, and various attractions installed in facilities such as amusement parks. The operation buttons are, for example, touch panel buttons that display a plurality of operation buttons for operating a car navigation, audio, air conditioner, driving support system, smartphone, tablet terminal, etc. mounted on an automobile.

[0026] Thereby, by moving and displaying the position of the operation button on the touch panel so as to shift according to the magnitude of the component in the direction perpendicular to the operation direction of the operation button, the operation button that was originally intended to be operated can be moved to the position of the operation button that was accidentally touched. As a result, misoperations on the operation buttons on the touch panel in a moving body such as an automobile can be effectively suppressed.

[0027] The misoperation detection method according to the 16th invention is a misoperation detection method for detecting misoperations in inputs to various operation buttons in a moving body, and includes an operation reception step, a detection step, and a misoperation determination step. In the operation reception step, an operation on an operation button is received. In the detection step, vibrations and shocks in the moving body are detected. In the misoperation determination step, when an operation on the operation button is received in the operation reception step when vibrations or shocks are detected in the detection step, it is determined whether it is a misoperation.

[0028] Here, for example, it is a device for detecting misoperations in inputs when operating operation buttons of various devices mounted on a moving body such as an automobile where vibrations and shocks are likely to occur, and when there is an input operation on the operation button at the timing when vibrations or shocks are detected, it is determined that it is a misoperation. Here, the moving body includes, for example, automobiles (including electric vehicles and hybrid vehicles), buses, railways, trucks, ships, airplanes, helicopters, drones, and various attractions installed in facilities such as amusement parks.

[0029] The operation buttons include, for example, operation buttons of car navigation, audio, air conditioning, driving support systems, smartphones, tablet terminals, etc. mounted on automobiles, and touch panel buttons. The determination of misoperation is performed, for example, according to the direction in which vibrations or shocks are applied with respect to the operation direction of the operation button.

[0030] The user who operates the operation button includes, for example, drivers of automobiles, buses, railways, trucks, etc., passengers, and pilots and passengers of airplanes, ships, etc. Thereby, when the operation button is operated at the timing when vibrations or shocks are applied to a moving body such as an automobile, it is possible to determine whether the operation is a misoperation. As a result, it is possible to detect misoperations when operating operation buttons of various devices mounted on a moving body where vibrations and shocks occur, and to take appropriate measures.

[0031] The incorrect operation detection program according to the 17th invention is an incorrect operation detection program for detecting incorrect operations of inputs to various operation buttons in a moving body, and causes a computer to execute an incorrect operation detection method including an operation reception step, a detection step, and an incorrect operation determination step. In the operation reception step, operations on the operation buttons are received. In the detection step, vibrations and impacts in the moving body are detected. In the incorrect operation determination step, when an operation on the operation button is received in the operation reception step when vibrations or impacts are detected in the detection step, it is determined whether it is an incorrect operation.

[0032] Here, for example, it is a device that detects incorrect operations of inputs when operating the operation buttons of various devices mounted on a moving body such as an automobile where vibrations and impacts are likely to occur, and determines that it is an incorrect operation if there is an input operation on the operation button at the timing when vibrations or impacts are detected. Here, the moving body includes, for example, automobiles (including electric vehicles and hybrid vehicles), buses, railways, trucks, ships, airplanes, helicopters, drones, and various attractions installed in facilities such as amusement parks.

[0033] The operation buttons include, for example, the operation buttons of car navigation, audio, air conditioner, driving support system, smartphone, tablet terminal, etc. mounted on an automobile, and touch panel buttons. The determination of incorrect operation is performed, for example, according to the direction in which vibrations or impacts are applied with respect to the operation direction of the operation button.

[0034] The user who operates the operation button includes, for example, the driver and passengers of automobiles, buses, railways, trucks, etc., and the pilots and passengers of airplanes, ships, etc. Thereby, when the operation button is operated at the timing when vibrations or impacts are applied to a moving body such as an automobile, it can be determined whether the operation is an incorrect operation. As a result, it is possible to detect incorrect operations when operating the operation buttons of various devices mounted on a moving body where vibrations and impacts occur, and take appropriate measures.

[0035] The misoperation suppression method according to the 18th invention is a misoperation suppression method for suppressing misoperations of inputs to various operation buttons on a touch panel in a moving body, and includes an operation reception step, a detection step, and a display control step. The operation reception step receives operations on the operation buttons. In the detection step, vibrations and impacts in the moving body are detected. In the display control step, when vibrations or impacts including a component in a direction opposite to the operation direction of the operation button and perpendicular to the operation direction are detected in the detection step and an operation on the operation button is received in the operation reception step, the position of the operation button on the touch panel is moved and displayed according to the magnitude of the component in the perpendicular direction.

[0036] Here, for example, it is a device that suppresses misoperations of inputs when operating operation buttons of various devices mounted on a moving body such as an automobile where vibrations and impacts are likely to occur. When there is an input operation to the operation button at the timing when vibrations or impacts including a component in a direction opposite to the operation direction of the operation button and perpendicular to the operation direction are detected, the position of the operation button on the touch panel is moved and displayed according to the magnitude of the component in the perpendicular direction.

[0037] Here, the moving body includes, for example, automobiles (including electric vehicles and hybrid vehicles), buses, railways, trucks, ships, airplanes, helicopters, drones, and various attractions installed in facilities such as amusement parks. The operation buttons are, for example, touch panel buttons that display a plurality of operation buttons for operating a car navigation, audio, air conditioner, driving support system, smartphone, tablet terminal, etc. mounted on an automobile.

[0038] Thereby, by moving and displaying the position of the operation button on the touch panel so as to shift according to the magnitude of the component in the direction perpendicular to the operation direction of the operation button, the operation button that was originally intended to be operated can be moved to the position of the operation button that was accidentally touched. As a result, misoperations on the operation buttons on the touch panel in a moving body such as an automobile can be effectively suppressed.

[0039] The misoperation suppression program according to the 19th invention is a misoperation suppression program for suppressing misoperations of inputs to various operation buttons on a touch panel in a moving body, and causes a computer to execute a misoperation suppression method including an operation reception step, a detection step, and a display control step. The operation reception step receives an operation on an operation button. In the detection step, vibrations and impacts in the moving body are detected. In the display control step, when vibrations or impacts including a component in a direction opposite to the operation direction of the operation button and perpendicular to the operation direction are detected in the detection step and an operation on the operation button is received in the operation reception step, the position of the operation button on the touch panel is moved and displayed according to the magnitude of the component in the perpendicular direction.

[0040] Here, for example, it is a device that suppresses misoperations of inputs when operating operation buttons of various devices mounted on a moving body such as an automobile where vibrations and impacts are likely to occur. When there is an input operation on an operation button at the timing when vibrations or impacts including a component in a direction opposite to the operation direction of the operation button and perpendicular to the operation direction are detected, the position of the operation button on the touch panel is moved and displayed according to the magnitude of the component in the perpendicular direction.

[0041] Here, the moving body includes, for example, automobiles (including electric vehicles and hybrid vehicles), buses, railways, trucks, ships, airplanes, helicopters, drones, and various attractions installed in facilities such as amusement parks. The operation button is, for example, a touch panel button that displays a plurality of operation buttons for operating a car navigation, audio, air conditioner, driving support system, smartphone, tablet terminal, etc. mounted on an automobile.

[0042] Thereby, by moving and displaying the position of the operation button on the touch panel so as to shift according to the magnitude of the component in the direction perpendicular to the operation direction of the operation button, the operation button that was originally intended to be operated can be moved to the position of the operation button that was accidentally touched. As a result, it is possible to effectively suppress an erroneous operation on an operation button on a touch panel in a moving body such as an automobile.

Embodiments for Carrying Out the Invention

[0045] The incorrect operation detection device 10 and the incorrect operation detection method according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 7. In this embodiment, detailed descriptions that are more detailed than necessary may be omitted. For example, detailed descriptions of well-known matters and duplicate descriptions of substantially the same configurations may be omitted. This is to avoid making the following descriptions unnecessarily redundant and to facilitate the understanding of those skilled in the art. Also, the applicant provides the accompanying drawings and the following description for those skilled in the art to fully understand the present invention, and does not intend to limit the subject matter described in the claims by these.

[0046] (1) Configuration of the incorrect operation detection device 10 The incorrect operation detection device 10 according to this embodiment is a device that detects incorrect operations related to operation inputs of in-vehicle navigation, car audio, air conditioners, smartphones, tablet terminals, etc. mounted on an automobile (mobile body). As shown in FIG. 1, it is connected to an in-vehicle system 20, operation buttons 21, a three-axis acceleration sensor 22, a speaker (output unit) 23, and a proximity sensor 24.

[0047] The in-vehicle system 20 is a system including, for example, in-vehicle navigation, audio, air conditioners, etc., and is operated by operation inputs to the operation buttons 21. The operation buttons 21 are provided around the driver's seat to perform various operations of the in-vehicle system 20 that controls in-vehicle navigation, audio, air conditioners, etc. The operation buttons 21 include various switches such as a touch panel type display for in-vehicle navigation, a reverse switch, and a push button switch.

[0048] The three-axis acceleration sensor 22 is provided, for example, to detect vibrations and impacts applied to a moving vehicle, detects the magnitude and direction of the vibrations and impacts, and transmits them to the malfunction detection device 10. The speaker (output unit) 23 is a device that outputs sound information such as a warning sound when determining a malfunction, which will be described later, and is controlled by the malfunction detection device 10 (output control unit 16).

[0049] The proximity sensor 24 is disposed near the operation button 21 and detects a finger F1 approaching the operation button 21. Here, the detection of the approach of the finger F1 by the proximity sensor 24 can be performed by known methods such as a capacitance type (self-capacitance method, mutual-capacitance method), a photoelectric type, an ultrasonic type (pulse method, FMCW (Frequency Modulated Continuous Wave) method), a magnetic detection method, an imaging device (CCD (Charge Coupled Device) method, CMOS (Complementary Metal Oxide Semi-conductor) method), etc. Also, for the distance from the operation button 21 to the finger F1, known methods such as a distance measuring reflection type PSD (Position Sensitive Detector) method or a two-segment PD (Photo Diode) method can be adopted.

[0050] The malfunction detection device 10 is provided to detect an incorrect operation (an operation not intended by the user) on the operation button 21. As shown in FIG. 1, it includes an operation reception unit 11, a vibration / impact detection unit (detection unit) 12, a malfunction determination unit 13, a sound selection unit 14, a sound information storage unit 15, an output control unit 16, and a distance calculation unit (finger proximity detection unit) 17. As shown in FIG. 1, the operation reception unit 11 receives an operation input for the operation button 21 that operates various devices included in the in-vehicle system 20.

[0051] As shown in FIG. 1, the vibration / impact detection unit (detection unit) 12 is connected to the three-axis acceleration sensor 22 and detects vibrations and impacts (magnitude and direction) applied to the vehicle. When the vibration / shock detection unit 12 detects vibration or shock, if the operation reception unit 11 receives an operation on the operation button 21, the malfunction determination unit 13 determines whether it is a malfunction.

[0052] More specifically, as shown in Fig. 2(a), when the vibration / shock detection unit 12 detects a component (black arrow in the figure) in the direction opposite to the operation direction of the operation button 21 (the direction of the solid arrow in the figure), if the operation reception unit 11 receives an input operation on the operation button 21, it is assumed that the user's finger F1 touches the operation button 21 unintentionally because vibration or shock is applied in the direction opposite to the operation direction from the state where the finger F1 is separated from the operation button 21. Therefore, when the malfunction determination unit 13 receives an operation on the operation button 21 when vibration or shock including a component in the direction opposite to the operation direction is detected, it determines this as a malfunction.

[0053] Also, as shown in Fig. 2(b), in a configuration where a plurality of operation buttons 21a, 21b, 21c are arranged side by side, when an operation on the operation button 21c is detected when vibration or shock is applied in the direction of the black arrow in the figure, it is assumed that the finger F1 was about to operate the adjacent operation button 21b and got close due to the direction of the vibration or the like, and then accidentally touched the adjacent operation button 21c due to the vibration or the like.

[0054] Therefore, in the configuration shown in Fig. 2(b), when the malfunction determination unit 13 receives an operation on the operation button 21 when vibration or shock including a component in the direction opposite to the operation direction is detected, it determines this as a malfunction. Here, for an operation determined to be a malfunction by the malfunction determination unit 13, the malfunction determination unit 13 may send a signal to the vehicle-mounted system 20 to invalidate the operation.

[0055] This can avoid the devices mounted on the vehicle-mounted system 20 being operated by an unintended operation determined to be a malfunction. According to the result of the incorrect operation determination by the incorrect operation determination unit 13, the sound selection unit 14 extracts appropriate sound information from the sound information storage unit 15 and transmits it to the output control unit 16 so that an appropriate sound is output from the speaker 23.

[0056] Specifically, when the incorrect operation determination unit 13 determines that it is not an incorrect operation, the sound selection unit 14, for example, extracts the operation sound output when operating the normal operation button 21 from the sound information storage unit 15 and transmits it to the output control unit 16. On the other hand, when the incorrect operation determination unit 13 determines that it is an incorrect operation, the sound selection unit 14, for example, extracts a warning sound different from the operation sound output when operating the normal operation button 21 from the sound information storage unit 15 and transmits it to the output control unit 16.

[0057] Note that when the environmental sound detection unit 14a detects environmental sounds including driving sounds and external sounds during the driving of the vehicle, the output control unit 16 may control so that sound waves that cancel out those environmental sounds are selected and output from the speaker 23. Thereby, the operation sound and warning sound output from the speaker 23 can be made easier for the user to hear.

[0058] The sound information storage unit 15 stores various sound information such as, for example, normal operation sounds, warning sounds issued based on the determination result of being an incorrect operation in the above-described incorrect operation determination, sounds that change according to the proximity distance to the operation button 21 of the finger F1, sounds that change according to the operated operation buttons 21a, 21b, 21c, and the like. The output control unit 16 controls the speaker 23 so that an appropriate sound is output from the speaker 23 according to the result of the incorrect operation determination by the incorrect operation determination unit 13.

[0059] Specifically, when the misoperation determination unit 13 determines that it is not a misoperation, the output control unit 16 controls the speaker 23 to output, for example, the operation sound output when operating the normal operation button 21. On the other hand, when the misoperation determination unit 13 determines that it is a misoperation, the output control unit 16 controls the speaker 23 to output, for example, a warning sound different from the operation sound output when operating the normal operation button 21.

[0060] Furthermore, the output control unit 16 controls the speaker 23 so that the sound output changes according to the distance to the operation button 21 of the finger F1 described later. Also, the output control unit 16 controls the speaker 23 so that different sounds are output for each type of operation buttons 21a, 21b, 21c operated by the finger F1. Note that when the misoperation determination unit 13 determines that it is a misoperation, for example, the output control unit 16 may control to output a warning sound different from the operation sound output from the speaker 23 when operating the normal operation button 21.

[0061] As shown in FIG. 1, the distance calculation unit (finger proximity detection unit) 17 is connected to the proximity sensor 24, calculates the distance between the detected finger F1 and the operation button 21 in the proximity sensor 24, and transmits it to the operation reception unit 11. Thereby, the operation reception unit 11, according to the result calculated by the distance calculation unit 17 (the distance to the operation button 21), for example, as shown in FIG. 3(a), when the distance between the finger F1 and the operation button 21 is large, the output control unit 16 controls the speaker 23 to output a low sound. On the other hand, for example, as shown in FIG. 3(b), when the distance between the finger F1 and the operation button 21 becomes small, the output control unit 16 controls the speaker 23 to output a high sound.

[0062] Note that the output control unit 16 may control the speaker 23 not to output a sound until the distance between the finger F1 and the operation button 21 becomes equal to or less than a predetermined distance, and to output a sound when the distance becomes equal to or less than the predetermined distance. As a result, even when the user is not looking at the direction of the operation button 21, the user can recognize that his or her finger is near the operation button 21.

[0063] Here, as shown in FIG. 4(a), in a configuration in which a plurality of operation buttons 21a, 21b, 21c are arranged, the output control unit 16 may control the speaker 23 so that different operation sounds are output for each of the operation buttons 21a, 21b, 21c operated by the finger F1. Alternatively, as shown in FIG. 4(b), in a configuration in which a plurality of operation buttons 21a, 21b, 21c are arranged, the output control unit 16 may control the speaker 23 so that an operation sound corresponding to the operation button 21b actually operated by the finger F1 is output.

[0064] Note that, as shown in FIG. 5, in a configuration in which a plurality of operation buttons 21a, 21b, 21c are arranged, when a hand H including a plurality of fingers approaches the operation buttons 21a, 21b, 21c, the plurality of operation buttons 21a, 21b, 21b may be linked as an array to output an error sound, or the operation may be invalidated by processing as if the operation button 21b corresponding to the finger that has come closest (the middle finger in FIG. 5) has been operated.

[0065] Further, the output control unit 16 may patternize the type of sound output from the speaker 23 according to the magnitude of the acceleration of vibration or impact detected by the three-axis acceleration sensor 22 (see FIG. 6). For example, as shown in FIG. 6, when the acceleration of vibration or impact detected by the three-axis acceleration sensor 22 (vibration / impact detection unit 12) is relatively large, the operation to the operation button 21 is invalidated, and the output sound output from the speaker 23 is set as a warning sound (pattern A).

[0066] Also, when the acceleration of vibration or impact detected by the three-axis acceleration sensor 22 (vibration / impact detection unit 12) is relatively small, the valid / invalid processing of the operation to the operation button 21 is excluded, and the output sound control output from the speaker 23 is also excluded (pattern A). When the acceleration of vibration or impact detected by the three-axis acceleration sensor 22 (vibration / impact detection unit 12) is small, the operation of the operation button 21 is enabled, and the output sound output from the speaker 23 is set to a normal operation sound (or no sound) (Pattern A).

[0067] On the other hand, in Pattern B, it may be set as follows. That is, as shown in FIG. 6, when the acceleration of vibration or impact detected by the three-axis acceleration sensor 22 (vibration / impact detection unit 12) is relatively large, the operation of the operation button 21 is disabled, and the output sound output from the speaker 23 is set to a warning sound A (Pattern B). Also, when the acceleration of vibration or impact detected by the three-axis acceleration sensor 22 (vibration / impact detection unit 12) is relatively small, the operation of the operation button 21 is enabled, and the output sound output from the speaker 23 is set to a warning sound B (Pattern B).

[0068] When the acceleration of vibration or impact detected by the three-axis acceleration sensor 22 (vibration / impact detection unit 12) is small, the operation of the operation button 21 is enabled, and the output sound output from the speaker 23 is set to a normal operation sound (or no sound) (Pattern B). In this way, by performing the valid / invalid processing of the operation on the operation button 21 and the control of the output sound output from the speaker 23 in a plurality of patterns, the user can select a pattern according to their preference.

[0069] <False operation detection method> The false operation detection device 10 of the present embodiment implements a false operation detection method according to the flowchart shown in FIG. 7. That is, in step S11, according to the detection result of the proximity sensor 24, the distance calculation unit 17 determines whether it is detected that the finger F1 has approached the operation button 21. Here, when the distance calculation unit 17 detects the approach of the finger F1, the process proceeds to step S12.

[0070] Next, in step S12, in a state where proximity of the finger F1 to the operation button 21 is detected in step S11, the vibration / shock detection unit 12 determines whether vibration or shock is detected by the three-axis acceleration sensor 22. Here, when the vibration / shock detection unit 12 detects vibration or shock in the three-axis acceleration sensor 22, the process proceeds to step S13. If vibration or shock is not detected, the process returns to step S11.

[0071] Next, in step S13, in a state where vibration or shock is detected by the vibration / shock detection unit 12 in step S12, the operation reception unit 11 determines whether an operation on the operation button 21 of the in-vehicle system 20 is received. Here, when it is determined that the operation reception unit 11 has received an operation on the operation button 21 of the in-vehicle system 20, the process proceeds to step S14. If it is determined that no operation is received, the process returns to step S11.

[0072] Next, in step S14, since an operation on the operation button 21 is detected in a state where vibration or shock is detected in step S13, the vibration / shock detection unit 12 detects the direction and acceleration of the vibration or shock. Next, in step S15, the vibration / shock detection unit 12 determines whether the detected direction of the vibration or shock includes a component opposite to the operation direction of the operation button 21. Here, if the direction of the vibration or shock includes a component opposite to the operation direction, the process proceeds to step S16. On the other hand, if it does not include a component opposite to the operation direction, it is determined that the possibility of an accidental operation due to vibration or shock is low, and the process returns to step S11.

[0073] Next, in step S16, based on the direction and acceleration of the vibration or shock detected in step S14, it is determined whether the moving speed / moving distance due to the vibration or shock is equal to or greater than a certain value. Here, if the moving speed / moving distance due to the vibration or shock is equal to or greater than a certain value, the process proceeds to step S17. On the other hand, if it is determined that the moving speed / moving distance due to the vibration or shock is less than a certain value, it is determined that no accidental operation has been performed, and the process returns to step S11.

[0074] Next, in step S17, the erroneous operation determination unit 13 determines whether the operation detected in step S13 is an erroneous operation based on the determination result in step S15 that the direction of vibration or impact includes a component opposite to the operation direction, and the determination result in step S16 as to whether the moving speed and moving distance due to vibration or impact are equal to or greater than a certain value. Specifically, as described above, when vibration or impact is detected by the vibration / impact detection unit 12 and the operation reception unit 11 receives an operation on the operation button 21, the erroneous operation determination unit 13 determines whether it is an erroneous operation based on the direction of the impact or vibration, and also determines whether the moving speed and moving distance due to vibration or impact are equal to or greater than a certain value.

[0075] More specifically, when a component (black arrow in the figure) opposite to the operation direction (solid arrow direction in the figure) of the operation button 21 is detected by the vibration / impact detection unit 12 and the operation reception unit 11 receives an input operation on the operation button 21, it is assumed that since vibration or impact with a moving speed and moving distance equal to or greater than a certain value in the direction opposite to the operation direction is applied from the state where the user's finger F1 is separated from the operation button 21, the finger F1 accidentally touches the operation button 21 (see Fig. 2(a)). Therefore, when the erroneous operation determination unit 13 receives an operation on the operation button 21 when vibration or impact including a component with a moving speed and moving distance equal to or greater than a certain value in the direction opposite to the operation direction is detected, it determines this as an erroneous operation.

[0076] Similarly, in a configuration where a plurality of operation buttons 21a, 21b, 21c are arranged side by side, when an operation on the operation button 21c is detected when vibration or impact is applied in the direction of the black arrow in the figure, it is assumed that when the finger F1 approaches the adjacent operation button 21b to operate it due to the direction of vibration or the like, it accidentally touches the adjacent operation button 21c due to vibration or the like (see Fig. 2(b)).

[0077] Therefore, in a configuration where a plurality of operation buttons 21a, 21b, and 21c are arranged side by side, when the misoperation determination unit 13 detects vibration or impact in the opposite direction of the operation direction and including a component of a movement speed and a movement distance equal to or greater than a certain level, if the operation of the operation button 21 is accepted, it determines this as a misoperation. Next, in step S17, in response to the determination result of misoperation in step S16, the output control unit 16 controls the speaker 23 to output a warning sound and ends the process.

[0078] <Main features> The misoperation detection device 10 of the present embodiment is a device that detects misoperation of inputs to various operation buttons 21, 21a to 21c in an automobile. As shown in FIG. 1, it includes an operation reception unit 11, a vibration / impact detection unit 12, and a misoperation determination unit 13. The operation reception unit 11 accepts operations on the operation buttons 21, 21a to 21c. The vibration / impact detection unit 12 detects vibration and impact in the automobile. When the vibration / impact detection unit 12 detects vibration or impact and the operation reception unit 11 accepts an operation on the operation buttons 21, 21a to 21c, the misoperation determination unit 13 determines whether it is a misoperation.

[0079] Thereby, when the user operates the operation buttons 21, 21a to 21c at the timing when vibration or impact is applied to a moving body such as an automobile, it is possible to determine whether the operation was performed as a misoperation due to the force of the vibration or impact. As a result, it is possible to detect misoperation when operating the operation buttons 21, 21a to 21c of various devices mounted on an automobile where vibration or impact occurs, and to take appropriate measures.

[0080] [Other embodiments] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention. (A) In the above-described embodiment, an example in which the present invention is realized has been described as the malfunction detection device 10 and the malfunction detection method. However, the present invention is not limited to this. For example, the present invention may be realized as a malfunction detection program that causes a computer to execute the above-described malfunction detection method.

[0081] This malfunction detection program is stored in a memory (storage unit) mounted on the malfunction detection device, and the CPU reads the malfunction detection program stored in the memory and causes the hardware to execute each step. More specifically, the CPU reads the malfunction detection program and executes the above-described operation reception step, detection step, malfunction determination step, and output control step, whereby the same effects as described above can be obtained. Further, the present invention may be realized as a recording medium storing the malfunction detection program.

[0082] (B) In the above-described embodiment, an example in which it is determined whether or not it is a malfunction according to the direction of vibration or impact when vibration or impact is applied during an operation on the operation button 21 or the like has been described. However, the present invention is not limited to this.

[0083] For example, as shown in FIG. 8, in a configuration in which operations of various devices included in the in-vehicle system 20 are performed through the touch panel 121, when the vibration / impact detection unit 12 detects vibration or impact including a component in a direction opposite to the operation direction of the operation button 21 and perpendicular to the operation direction, and the operation reception unit 111 receives an operation on the operation button 21, it may be a malfunction suppression device 110 that moves and displays the position of the operation button 21 on the touch panel 121 according to the magnitude of the component in the direction perpendicular to the display control unit 113.

[0084] Accordingly, by moving and displaying the display position of the operation button 21 on the touch panel 121 so as to shift it according to the magnitude and direction of the component in the direction perpendicular to the operation direction of the operation button 21, the operation button 21 that was originally intended to be operated can be moved to the position of the operation button 21 that was accidentally touched. As a result, it is possible to effectively suppress an erroneous operation on the operation button 21 on the touch panel 121 in a moving body such as an automobile.

[0085] Also, the erroneous operation suppression method by the erroneous operation suppression device 110 shown in FIG. 8 is performed according to the flowchart shown in FIG. 9. That is, in step S21, the vibration / shock detection unit 12 determines whether vibration or shock has been detected by the three-axis acceleration sensor 22. Here, when the vibration / shock detection unit 12 detects vibration or shock in the three-axis acceleration sensor 22, the process proceeds to step S22. If no vibration or shock has been detected, the process returns to step S21.

[0086] Next, in step S22, in the state where vibration or shock has been detected by the vibration / shock detection unit 12 in step S21, the operation reception unit 11 determines whether an operation on the operation button 21 of the in-vehicle system 20 has been received. Here, when it is determined that the operation reception unit 11 has received an operation on the operation button 21 of the in-vehicle system 20, the process proceeds to step S23. If it is determined that no operation has been received, the process returns to step S21.

[0087] Next, in step S23, since an operation on the operation button 21 has been detected in the state where vibration or shock has been detected in step S22, the vibration / shock detection unit 12 detects the direction and acceleration of the vibration or shock. Next, in step S24, the vibration / shock detection unit 12 determines whether the detected vibration or shock direction includes a component opposite to the operation direction of the operation button 21 and a component perpendicular to the operation direction. Here, if the vibration or shock direction includes components opposite to and perpendicular to the operation direction, the process proceeds to step S25. On the other hand, if it does not include components opposite to and perpendicular to the operation direction, it is determined that the possibility of an accidental operation due to vibration or shock is low, and the process returns to step S21.

[0088] Next, in step S25, based on the direction and acceleration of the vibration or shock detected in step S23, it is determined whether the moving speed / moving distance due to the vibration or shock is equal to or greater than a certain value. Here, if the moving speed / moving distance due to the vibration or shock is equal to or greater than a certain value, the process proceeds to step S26. On the other hand, if it is determined that the moving speed / moving distance due to the vibration or shock is less than a certain value, it is determined that no accidental operation has been performed, and the process returns to step S21.

[0089] Next, in step S26, since it is determined in step S24 that the detected vibration or shock direction includes a component opposite to the operation direction of the operation button 21 and a component perpendicular to the operation direction, and it is determined in step S25 that the moving speed / moving distance due to the vibration or shock is equal to or greater than a certain value, it is assumed that the user has operated the operation button 21c adjacent to the operation button 21b that was intended to be operated. Therefore, the display control unit 113 performs display control to move the arrangement of the operation button 21b on the touch panel 121, for example, to the position of the original operation button 21c.

[0090] Here, the distance and direction for moving the position of the operation button 21 are set according to the magnitude and direction of the component perpendicular to the operation direction detected in step S24. As a result, when the detected vibration or impact direction includes a component opposite to the operation direction of the operation button 21 and a component perpendicular to the operation direction, and the moving speed and moving distance due to the vibration or impact are equal to or greater than a certain value, by moving the position of the operation button 21 displayed on the touch panel 121 according to the magnitude of the perpendicular component, it is possible to suppress the operation of the operation button 21 that the user does not intend and perform the intended operation of the operation button 21.

[0091] Note that the present invention may be realized as an erroneous operation suppression program that causes a computer to execute the erroneous operation suppression method shown in FIG. 9. This erroneous operation suppression program is stored in a memory (storage unit) mounted on the erroneous operation suppression device, and the CPU reads the erroneous operation suppression program stored in the memory and causes the hardware to execute each step. More specifically, by the CPU reading the erroneous operation suppression program and executing the above-described operation reception step, detection step, and display control step, the same effects as described above can be obtained. Also, the present invention may be realized as a recording medium storing the erroneous operation suppression program.

[0092] (C) In the above embodiment, an example has been described in which, for an operation determined to be an erroneous operation by the erroneous operation determination unit 13, the erroneous operation determination unit 13 transmits a signal instructing the in-vehicle system 20 to invalidate the operation (see FIG. 6). However, the present invention is not limited to this. For example, as the process when an erroneous operation is determined, it may be a process of only outputting a warning sound without invalidating the operation itself.

[0093] (D) In the above embodiment, an example has been described in which the output control unit 16 controls the speaker 23 to output a sound wave that includes this ambient sound from the speaker 23 according to the magnitude and type of the ambient sound detected by the ambient sound detection unit 14a. However, the present invention is not limited to this. For example, a configuration without an environmental sound detection unit for detecting environmental sound may be used.

[0094] (E) In the above embodiment, an example in which a distance calculation unit (finger proximity detection unit) 17 for detecting the proximity of a finger attempting to operate the operation button 21 is provided has been described. However, the present invention is not limited to this. For example, a configuration without a finger proximity detection unit for detecting the proximity of a finger attempting to operate an operation button may be used.

[0095] (F) In the above embodiment, an example in which a warning sound different from a normal operation sound is output from a speaker or the like when a malfunction is detected has been described. However, the present invention is not limited to this. For example, when a malfunction is detected, a configuration including a vibration generation unit (vibration motor, piezoelectric element, etc.) that generates vibration in a portion including the operation button may be used instead of outputting sound. Even in this case, the user can recognize that it was a malfunction by the vibration generated in the portion including the operation button.

[0096] (G) In the above embodiment, as operation buttons for various devices mounted on a moving body, operation buttons such as car navigation, audio, air conditioner, etc. and touch panel buttons mounted on an automobile have been described as examples. However, the present invention is not limited to this. For example, operation buttons such as a driving support system, a smartphone, a tablet terminal, etc. mounted on an automobile, and touch panel buttons may be used.

[0097] (H) In the above embodiment, an automobile has been described as an example of a moving body to which the present invention is applied. However, the present invention is not limited to this. For example, the moving body to which the present invention is applied may be various attractions installed in facilities such as electric vehicles, hybrid vehicles, trucks, buses, railways, ships, airplanes, helicopters, drones, amusement parks, etc., in addition to automobiles.
