[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-053734 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-054320 [Patent Document 3] Japanese Patent Application Laid-Open No. 2017-005650 Summary of the Invention [Problem to be solved by the invention]

[0006] To reduce power consumption, some devices are equipped with a motion sensor that detects the presence of a user. The motion sensor activates the device when it detects the presence of a user near the device, and switches to energy-saving mode when it does not detect the presence of a user near the device for a certain period of time, thereby effectively reducing power consumption.

[0007] In addition to the case where a single motion sensor is used as a motion sensor mounted on a device, multiple motion sensors may be used in combination. For example, when two motion sensors are used in combination, the motion sensors are designated as a first sensor and a second sensor. The first sensor constantly monitors, and when the first sensor detects the presence of a user, the second sensor is activated. In this way, by using the first sensor and the second sensor in combination, the presence or absence of a user can be doubly confirmed. Therefore, there is a mechanism for detecting the presence or absence of a user around the device more accurately than when using only a single sensor.

[0008] The detection accuracy of the first sensor may decrease depending on the environment around the device, resulting in detection malfunctions. For example, if the first sensor does not respond even though a user is present near the device, the device will not start up, which is easily noticed by the user. However, if the first sensor makes a false detection even though there is no user near the device, and the device does not switch to energy-saving mode, it is difficult for the user to notice the malfunction. If the malfunction caused by the false detection of the first sensor is left unattended, the second sensor will continue to operate and the device will not switch to energy-saving mode, making it impossible to effectively reduce the power consumption of the device.

[0009] The present invention aims to provide an information processing device and an information processing program that, when a first sensor that detects the presence or absence of a user and a second sensor are used in combination, can notify of a false detection by the first sensor that detects the presence or absence of a user as a trigger for activating the second sensor. [Means for solving the problem]

[0010] An information processing device according to a first aspect includes a processor, which controls the detection of the presence or absence of a user using a first sensor that detects the presence or absence of a user and a second sensor that is activated when the first sensor detects the presence of a user, and notifies the first sensor of a false detection when a state in which the first sensor detects the presence of a user but the second sensor does not detect the presence of a user satisfies a predetermined condition.

[0011] In the information processing device of the second aspect, the processor notifies the first sensor of a false detection when the number or frequency of times when the first sensor detects the presence of a user but the second sensor does not detect the presence of a user exceeds a predetermined threshold.

[0012] In the information processing device according to the third aspect, the processor notifies the first sensor of a false detection when both the first sensor and the second sensor detect the presence of a user for the first time after the predetermined condition is met.

[0013] In the information processing device according to a fourth aspect, the processor notifies the user of the erroneous detection of the first sensor by displaying the notification on a display unit serving as a user interface.

[0014] In the information processing device according to a fifth aspect, the processor displays, on the display unit, a screen that enables adjustment of the first sensor when the predetermined condition is satisfied.

[0015] In the information processing device of the sixth aspect, the processor makes it possible to adjust the first sensor by displaying the display unit while the first sensor detects the presence of a user, and not displaying the display unit while the first sensor does not detect the presence of a user.

[0016] In the information processing device according to the seventh aspect, the processor stops display by the display unit when the first sensor detects the presence of a user but the second sensor does not detect the presence of a user.

[0017] In the information processing device according to an eighth aspect, after the processor stops displaying on the display unit, when the second sensor next detects the presence of a user, the processor resumes displaying on the display unit.

[0018] An information processing program according to a ninth aspect causes a computer to control the detection of the presence or absence of a user using a first sensor that detects the presence or absence of a user and a second sensor that is activated when the first sensor detects the presence of a user, and notifies the computer of a false detection by the first sensor when a state in which the first sensor detects the presence of a user but the second sensor does not detect the presence of a user satisfies a predetermined condition. [Effects of the Invention]

[0019] According to the information processing device of the first aspect, when a first sensor and a second sensor for detecting the presence or absence of a user are used in combination, it is possible to notify a false detection of the first sensor for detecting the presence or absence of a user as a trigger for activating the second sensor.

[0020] According to the information processing device of the second aspect, it is possible to identify erroneous detection by the first sensor using the threshold as a reference.

[0021] According to the information processing device of the third aspect, the user can be made more reliably aware of the occurrence of a malfunction due to a false detection by the first sensor, compared to a notification that is made at the time when the occurrence of a malfunction due to a false detection by the first sensor is detected.

[0022] According to the information processing device of the fourth aspect, the occurrence of a malfunction due to erroneous detection by the first sensor can be made known to the user as visible information.

[0023] According to the information processing device of the fifth aspect, it is possible for the user to take action in the event of a malfunction caused by erroneous detection by the first sensor.

[0024] According to the information processing device of the sixth aspect, the user can actually check whether or not a malfunction due to erroneous detection by the first sensor has occurred as visible information.

[0025] According to the information processing device of the seventh aspect, when the first sensor makes an erroneous detection, the display is stopped, thereby making it possible to prevent waste of power due to the erroneous detection.

[0026] According to the information processing device of the eighth aspect, the display can be resumed by detection by the second sensor, making it possible for the user to perform an operation.

[0027] According to the information processing program of the ninth aspect, when a first sensor that detects the presence or absence of a user and a second sensor are used in combination, it is possible to notify of a false detection by the first sensor that detects the presence or absence of a user as a trigger to activate the second sensor.

[0029] Hereinafter, an example of an embodiment of the disclosed technology will be described in detail with reference to the drawings.

[0030] 1 is a diagram illustrating an outline of a device 1 including an information processing device 10 according to this embodiment, and a human presence sensor (not shown) mounted on the device 1. The information processing device 10 according to this embodiment is included in the device 1. The information processing device 10 may be built into the device 1, or may be attached to the device 1 as an external device. The information processing device 10 may also be connected to other devices and terminals via a network so as to be able to communicate with them. Examples of this network include the Internet, a LAN (Local Area Network), and a WAN (Wide Area Network).

[0031] 1 is, for example, a multifunction peripheral that combines the functions of a copier, printer, image scanner, and facsimile machine. However, the present invention is not limited to this. Device 1 is not always used by a user, but is operated by the user only when in use.

[0032] The device 1 is equipped with a human presence sensor. There are various types of human presence sensors, depending on the power consumption, detection accuracy, etc. For example, there are pyroelectric sensors that consume less power and have lower detection accuracy, and reflective sensors that consume more power and have higher detection accuracy than pyroelectric sensors. In this embodiment, an example is shown in which the device 1 is equipped with a pyroelectric sensor and a reflective sensor as two types of human presence sensors.

[0033] A pyroelectric sensor is a sensor that uses the pyroelectric effect of a pyroelectric element, and one example of a pyroelectric sensor is a pyroelectric infrared sensor. A pyroelectric infrared sensor converts a rise in temperature into an electrical signal, and therefore detects the approach of a human body by detecting temperature changes due to infrared rays naturally emitted from objects that have temperature, such as the human body.

[0034] A reflective sensor is a sensor that has a light-emitting part and a light-receiving part, and an example of a reflective sensor is a reflective infrared sensor. A reflective infrared sensor detects the presence or absence of a user by whether or not light entering the light-receiving part is blocked.

[0035] Due to the above-mentioned characteristics, pyroelectric sensors and reflective sensors differ in their detection range and detection accuracy for detecting the presence or absence of a user. The two dotted lines a and A in Figure 1 indicate the detection ranges of pyroelectric sensors and reflective sensors (not shown). Dotted line A indicates the detection range of the pyroelectric sensor. Because pyroelectric sensors detect the approach of a human body, they have a relatively wide detection range. However, because they detect temperature changes due to infrared rays, they can also detect the presence of a user simply passing by device 1. Dotted line a indicates the detection range of the reflective sensor. Reflective sensors detect the presence or absence of a user based on whether or not light entering the light-receiving section is blocked, so their detection range is narrower than that of pyroelectric sensors, depending on the amount of light emitted from the light-emitting section. However, reflective sensors have higher detection accuracy because they detect the presence of a user near device 1. Furthermore, reflective sensors generally consume more power than pyroelectric sensors. In the following explanation, pyroelectric sensors will be referred to as the first sensor and reflective sensors as the second sensor.

[0036] In this embodiment, the first sensor operates constantly and continues to monitor the presence or absence of a user. When the first sensor detects the presence of a user, the second sensor is activated and detects the presence or absence of the user. By using the first sensor and the second sensor in combination, the presence or absence of a user near the device 1 can be detected more reliably than when a single human presence sensor is used. Furthermore, as described above, power consumption can be reduced more effectively by operating the second sensor only when the first sensor detects the presence of a user, rather than operating the second sensor constantly.

[0037] Next, the configuration of the information processing device 10 will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the hardware configuration of the information processing device 10 according to this embodiment.

[0038] 2, an information processing device 10 according to this embodiment includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a storage 14, an input unit 15, a monitor 16, a communication interface (communication I / F) 17, a first sensor 18A, and a second sensor 18B. The CPU 11, the ROM 12, the RAM 13, the storage 14, the input unit 15, the monitor 16, and the communication I / F 17 are interconnected by a bus 19. Here, the CPU 11 is an example of a processor.

[0039] The CPU 11 supervises and controls the entire information processing device 10. The ROM 12 stores various programs, including the information processing program used in this embodiment, and data. The RAM 13 is a memory used as a work area when various programs are executed. The CPU 11 performs processing to display each image and character string by expanding the program stored in the ROM 12 into the RAM 13 and executing it. The storage 14 is, for example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), or a flash memory. The storage 14 may store the information processing program, etc. The input unit 15 is, for example, a mouse and a keyboard that accept character input, etc. The monitor 16 displays each screen. The communication I / F 17 transmits and receives data. As described above, the first sensor 18A is a pyroelectric sensor in this embodiment, and the second sensor 18B is a reflective sensor in this embodiment.

[0040] Next, the functional configuration of the information processing device 10 will be described with reference to Fig. 3. Fig. 3 is a block diagram showing an example of the functional configuration of the information processing device 10 according to this embodiment.

[0041] 3, the information processing device 10 has, as its functional components, a control unit 101 and a notification unit 102. The CPU 11 executes an information processing program to function as the control unit 101 and the notification unit 102.

[0042] The control unit 101 controls the detection of the presence or absence of a user using a first sensor 18A that detects the presence or absence of a user and a second sensor 18B that is activated when the first sensor 18A detects the presence of a user.

[0043] The control unit 101 keeps the first sensor 18A in operation at all times, and when the first sensor 18A detects the presence of a user in the vicinity of the device 1, it activates the second sensor 18B.

[0044] The notification unit 102 notifies the first sensor 18A of a false detection when a state in which the first sensor 18A detects the presence of a user but the second sensor 18B does not detect the presence of a user satisfies a predetermined condition.

[0045] A false detection by the first sensor 18A refers to a state in which the first sensor 18A detects the presence of a user but the second sensor 18B does not detect the presence of a user. As described above, a malfunction in which the first sensor 18A does not react even though a user is present around the device 1 is easily noticed by the user because the device 1 does not start up. However, a malfunction in which the first sensor 18A falsely detects even though a user is not present around the device 1 and the device does not switch to energy saving mode is difficult for the user to notice. Therefore, the notification unit 102 notifies the user of the false detection by the first sensor 18A when the false detection by the first sensor 18A satisfies a predetermined condition.

[0046] The predetermined condition is a condition that serves as a criterion when notifying the user of the occurrence of a false detection by the first sensor 18 A. The predetermined condition can be arbitrarily set by the user.

[0047] For example, the notification unit 102 notifies the first sensor 18A of a false detection when the number or frequency of the first sensor 18A detecting the presence of a user but the second sensor 18B not detecting the presence of a user exceeds a predetermined threshold.

[0048] An example of a predetermined condition is when the number or frequency of occurrences in which the second sensor 18B does not detect the user's presence despite the first sensor 18A detecting the user's presence exceeds a predetermined threshold. The number or frequency of occurrences in which the second sensor 18B does not detect the user's presence despite the first sensor 18A detecting the user's presence may be the number or frequency of false detections by the first sensor 18A in a predetermined period. Examples include occurrences in which the number of false detections by the first sensor 18A reaches 50 times relative to the number of activations of the device 1 in a month, or occurrences in which the frequency of false detections relative to the number of activations of the device 1 in a month reaches 10%. However, the predetermined condition for notifying the user of a false detection by the first sensor 18A is not limited to this. The number or frequency of occurrences in which the second sensor 18B does not detect the user's presence despite the first sensor 18A detecting the user's presence can be set by the user. For example, the threshold number can be set in units of a week, a day, or an hour, rather than in units of a month.

[0049] Furthermore, the notification unit 102 notifies the user of the erroneous detection by the first sensor 18A when both the first sensor 18A and the second sensor 18B detect the presence of the user for the first time after a predetermined condition is satisfied.

[0050] The notification unit 102 notifies the user of a false detection by the first sensor 18A when a predetermined condition is satisfied, but when both the first sensor 18A and the second sensor 18B detect the presence of a user for the first time after the predetermined condition is satisfied. As described above, a false detection by the first sensor 18A is a defect that detects the presence of a user even though the user is not present around the device 1. Therefore, even if a notification is made when the false detection by the first sensor 18A satisfies a predetermined condition, the user may not notice the notification. Therefore, the notification unit 102 notifies the user of a false detection by the first sensor 18A when the device 1 starts up normally after the predetermined condition is satisfied, that is, when the user is definitely present around the device 1.

[0051] Furthermore, the notification unit 102 notifies the user of the erroneous detection by the first sensor 18A by displaying the notification on the display unit as a user interface.

[0052] One example of a notification mode performed by the notification unit 103 is to display the notification on the monitor 16, which is a display unit serving as a user interface provided in the device 1. However, the notification mode of the notification unit 102 is not limited to this. Other examples of notification modes performed by the notification unit 103 include a mode in which the notification unit 102 directly notifies the user who is the administrator of the device 1 by email or the like via a network, or a mode in which a lamp or the like provided in the device 1 is blinked or the like.

[0053] FIG. 4 is a diagram illustrating an example of a display of a false detection notification of the first sensor 18A on the monitor 16, which is a display unit serving as a user interface. When a state in which the first sensor 18A detects the presence of a user but the second sensor 18B does not detect the presence of a user satisfies a predetermined condition, the notification unit 102 displays a message on the monitor 16 as shown in FIG. 4 to alert the user. In FIG. 4, as shown in display box 20, a message indicating the possibility of a false detection occurring in the first sensor 18A is displayed as "Possible false detection failure in the sensor." Furthermore, as shown in display box 21, an actual situation indicating the possibility of a false detection occurring in the first sensor 18A may be displayed. As an example, FIG. 4 illustrates that the first sensor 18A caused 50 false detections out of 6,730 times the device 1 was activated during the one-month period from April 1 to April 28.

[0054] Furthermore, when a predetermined condition is met, the notification unit 102 displays a screen on the display unit that allows the first sensor 18A to be adjusted.

[0055] In addition, the notification unit 102 displays the display unit while the first sensor 18A detects the presence of a user, and does not display the display unit while the first sensor 18A does not detect the presence of a user, thereby making it possible to adjust the first sensor 18A.

[0056] FIG. 5 is a diagram illustrating an example of a screen that allows adjustment of the first sensor 18A. As shown in FIG. 5, the screen that allows adjustment of the first sensor 18A displays, for example, “User Detecting” in the display box 23 as an adjustment mode when the first sensor 18A detects a user. On the other hand, when the first sensor 18A does not detect a user, the display box 23 displays “User Not Detected.” By visually displaying whether the first sensor 18A is detecting the presence or absence of a user, the user can confirm whether the first sensor 18A is operating normally. The user can adjust the installation environment of the device 1 while checking whether the first sensor 18A is operating normally by looking at the monitor 16, which is the display unit, to adjust the first sensor 18A. The example shown in FIG. 5 is merely an example, and the screen that allows adjustment of the first sensor 18A may further display a screen that allows adjustment of the sensitivity, etc., of the first sensor 18A.

[0057] When the notification unit 102 displays a notification of the erroneous detection of the first sensor 18A on the monitor 16, the user may optionally select to transition from the screen notifying the erroneous detection of the first sensor 18A to a screen that allows the first sensor 18A to be adjusted. For example, as shown in display box 22 in Fig. 4, the user may press a button labeled "Transition to sensor adjustment mode" to transition from the screen notifying the erroneous detection of the first sensor 18A to a screen that allows the first sensor 18A to be adjusted.

[0058] Furthermore, when the first sensor 18A detects the presence of a user but the second sensor 18B does not detect the presence of a user, the notification unit 102 stops the display on the display unit.

[0059] Furthermore, after the notification unit 102 stops displaying on the display unit, when the second sensor next detects the presence of the user, the notification unit 102 resumes displaying on the display unit.

[0060] In this way, in the adjustment mode, the notification unit 102 stops display on the monitor 16, which is the display unit, when the first sensor 18A detects the presence of a user but the second sensor 18B does not detect the presence of a user. Stopping the display on the monitor 16, which is the display unit, can be done, for example, by turning off the backlight of the monitor 16. On the other hand, after stopping the display on the display unit, the notification unit 102 resumes display on the display unit when the first sensor 18A next detects the presence of a user. The notification unit 102 stops or resumes display on the monitor 16, which is the display unit, depending on the presence or absence of a user around the device 1 detected by the first sensor 18A and the second sensor 18B. By stopping or resuming display on the monitor 16, the user can determine from a distance whether the first sensor 18A is operating normally. For example, if the monitor 16 continues to display the information even though there is no user in the vicinity of the device 1, even a user who is a little far from the device 1 can recognize at a glance that there is a possibility that the first sensor 18A is experiencing a false detection problem.

[0061] Next, the operation of the information processing device 10 according to this embodiment will be described. Fig. 6 is a flowchart showing the processing of the information processing device according to this embodiment. The processing of the information processing device 10 according to this embodiment is performed by the CPU 11 reading and executing an information processing program stored in the RAM 13 or the like.

[0062] In step S101, the CPU 11, functioning as the control unit 101, controls the first sensor 18A to determine whether or not the presence of a user has been detected around the device 1. If the presence of a user has been detected around the device 1 (step S101: YES), the process proceeds to step S102. If the presence of a user has not been detected around the device 1 (step S101: NO), the process proceeds to step S106.

[0063] In step S102, the CPU 11, functioning as the control unit 101, controls the second sensor 18B to determine whether or not the presence of a user has been detected around the device 1. If the presence of a user has been detected around the device 1 (step S102: YES), the process proceeds to step S103. If the presence of a user has not been detected around the device 1 (step S102: NO), the process proceeds to step S108.

[0064] In step S103, the CPU 11 determines whether the flag related to the erroneous detection of the first sensor 18A is ON. If the flag related to the erroneous detection of the first sensor 18A is ON (step S103: YES), the process proceeds to step S114. If the flag related to the erroneous detection of the first sensor 18A is not ON (step S103: NO), the process proceeds to step S104. The flag related to the erroneous detection of the first sensor 18A will be described later.

[0065] In step S104, the CPU 11 functions as the control unit 101 to start up the device 1.

[0066] In step S105, the CPU 11 functions as the control unit 101 to switch to the normal operation mode so that the normal functions of the device 1 can be executed, and the process returns to step S101.

[0067] In step S106, the CPU 11, functioning as the notification unit 102, turns off the backlight of the monitor 16, which is a display unit serving as a user interface.

[0068] In step S107, the CPU 11 functions as the control unit 101 to switch the device 1 to the power saving mode. In the power saving mode, power consumption is reduced more than in the normal operation mode.

[0069] In step S108, the CPU 11, functioning as the control unit 101, determines whether a certain time has passed without the second sensor 18B detecting the user. If the certain time has passed without the second sensor 18B detecting the user (step S108: YES), the process proceeds to step S109, and if the certain time has not passed without the second sensor 18B detecting the user (step S108: NO), the process returns to step S102, where detection by the second sensor 18B continues.

[0070] In step S109, the CPU 11, functioning as the control unit 101, determines whether the first sensor 18A detects the presence of a user. If the first sensor 18A detects the presence of a user (step S109: YES), the process proceeds to step S110. If the first sensor 18A does not detect the presence of a user (step S109: NO), the process proceeds to step S106, where the backlight of the monitor 16 is turned off.

[0071] In step S110, the CPU 11 as the control unit 101 detects erroneous detection by the first sensor 18A.

[0072] In step S111, the CPU 11 as the control unit 101 counts up the number or frequency of false detections of the first sensor 18A.

[0073] In step S112, the CPU 11, functioning as the control unit 101, determines whether the number of times false detections have been detected by the first sensor 18A is equal to or greater than a threshold value. The threshold value is an example of the predetermined condition described above. If the number of times false detections have been detected is equal to or greater than the threshold value (step S112: YES), the process proceeds to step S113. If the number of times false detections have been detected is not equal to or greater than the threshold value (step S112: NO), the process proceeds to step S106, and the user interface is turned off.

[0074] In step S113, the CPU 11 as the control unit 101 turns on a flag relating to erroneous detection by the first sensor 18A.

[0075] In step S114, the CPU 11 notifies the user as the notification unit 102. Step S114 is executed when the flag is turned ON in step S113 and the user is detected by both the first sensor 18A and the second sensor 18B next time. In other words, the user is notified of the erroneous detection by the first sensor 18A when he or she uses the device 1 for the first time after the flag is turned ON.

[0076] In step S115, the CPU 11 functions as the control unit 101 to switch to the adjustment mode for the first sensor 18A. The adjustment mode is as described above.

[0077] In step S116, CPU 11, functioning as control unit 101, accepts the user's adjustment of first sensor 18A and adjusts first sensor 18A.

[0078] In step S117, the CPU 11 as the control unit 101 turns off the flag relating to the erroneous detection of the first sensor 18A, and the process proceeds to step S105.

[0079] As described above, according to the information processing device 10 of this embodiment, when the first sensor 18A that detects the presence or absence of a user and the second sensor 18B are used in combination, it is possible to notify of a false detection by the first sensor 18A that detects the presence or absence of a user as a trigger to activate the second sensor 18B.

[0080] In the present embodiment, the first sensor 18A is a pyroelectric sensor and the second sensor 18B is a reflective sensor. However, this is not limited to this. The first sensor 18A may also be a reflective sensor. Furthermore, the first sensor 18A is not limited to a pyroelectric sensor or a reflective sensor.

[0081] In the present embodiment, the information processing program is installed in RAM 13, but the present invention is not limited to this. The information processing program according to the present embodiment may be provided in a form recorded on a computer-readable storage medium. For example, the information processing program according to the present embodiment may be provided in a form recorded on an optical disc such as a CD (Compact Disc)-ROM or a DVD (Digital Versatile Disc)-ROM, or in a form recorded on a semiconductor memory such as a USB (Universal Serial Bus) memory or a memory card. The information processing program according to the present embodiment may also be obtained from an external device via a communication line connected to the communication I / F 17.

[0082] In the above embodiment, the term "processor" refers to a processor in a broad sense, and includes general-purpose processors (e.g., CPU: Central Processing Unit, etc.) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.). Furthermore, the operations of the processors in the above embodiments may not only be performed by a single processor, but may also be performed by multiple processors located in physically separate locations working together. Furthermore, the order of the operations of the processors is not limited to the order described in the above embodiments, and may be changed as appropriate. [Explanation of symbols]
