BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

<Configuration of information processing system>
FIG. 1 is a diagram showing an information processing system 1 of this embodiment.
The information processing system 1 includes an electronic timepiece 10 (electronic device) and a smart phone 20 .

The electronic timepiece 10 is a wristwatch worn on a user's wrist. The electronic timepiece 10 includes a body portion 101 provided with a display portion 13 and operation buttons 141 and the like, and a belt 102 attached to the body portion 101 . The display unit 13 performs digital display in a dot matrix format. The display unit 13 of the electronic timepiece 10 displays basic information such as time and date, as well as measurement results of the user's pulse rate (heart rate). The electronic timepiece 10 can be communicatively connected to the smartphone 20 by short-range wireless communication. Short-range wireless communication includes, but is not limited to, Bluetooth (registered trademark). Hereinafter, the state in which the electronic timepiece 10 and the smartphone 20 are connected to each other via short-range wireless communication is also referred to as pairing.

FIG. 2 is a side view of the electronic timepiece 10. FIG.
Electronic timepiece 10 includes pulse sensor 18 having light emitting portion 181 and light receiving portion 182 inside body portion 101 . The light-emitting portion 181 and the light-receiving portion 182 are provided near the back surface of the main body portion 101, that is, the surface that touches the user's wrist when worn. The light emitting portion 181 emits light from the back surface of the main body portion 101 toward the outside. When the electronic timepiece 10 is worn by the user, the light emitted from the light emitting section 181 is reflected by the skin of the user's wrist. The light receiving section 182 is provided at a position capable of receiving the light reflected by the user's skin. A part of the light irradiated to the user's skin is absorbed by the blood in the blood vessels. Therefore, the amount of reflected light from the skin received by the light receiving unit 182 changes over time in accordance with changes in blood flow due to heart pulsation. A pulse is detected based on the change in the amount of light received, and a pulse rate is measured based on the detected pulse.

A smartphone 20 shown in FIG. 1 is a terminal device that is mainly carried and used by a user, and has a call function, a data communication function, and various information processing functions. The smartphone 20 performs various cooperative operations by transmitting and receiving data to and from the paired electronic timepiece 10 , and displays information and the like related to the cooperative operations on the display unit 23 . As the cooperative operation of the electronic timepiece 10 and the smartphone 20, for example, when an event occurs in the smartphone 20 to notify the user, the electronic timepiece 10 performs an operation of notifying the user in conjunction with the occurrence of the event. be. Since the electronic timepiece 10 is used by being worn by the user, it is possible to make the user aware of the occurrence of the event more reliably by performing the notification on the electronic timepiece 10 . The above events may include, for example, reception of messages such as e-mails and news, and arbitrary events occurring on applications of the smartphone 20 . In addition, it is possible to perform cooperative operation such as displaying the pulse rate measured by the electronic timepiece 10 on the smart phone 20 .

<Operation of information processing system>
Next, the operation of the information processing system 1 will be described, focusing on the operation related to the wearing determination by the electronic timepiece 10 and the operation related to the notification control.

As described above, the electronic timepiece 10 measures the user's pulse rate while worn on the user's body (hereinafter referred to as "wearing state") and displays the measurement result. The measurement of the pulse rate is performed periodically, for example, repeatedly at intervals of 10 minutes, and the measurement result is displayed on the display unit 13 each time. The pulse rate is one aspect of the user's biometric information, and the process of measuring the pulse rate is one aspect of the information acquisition process of acquiring the biometric information. The process of measuring the pulse rate is one aspect of the process that is executed on the premise that the electronic timepiece 10 is worn.

When the pulse rate measurement process is executed while the electronic timepiece 10 is not worn on the user's body (hereinafter referred to as the "non-wearing state"), unnecessary light is emitted from the light emitting unit 181 and light is received. Since meaningless pulse detection processing is executed based on the detection result of external light by the unit 182, power consumption is wasted. In addition, unnecessary light emission from the light emitting unit 181 is visually recognized by the user, which is not preferable in terms of appearance. Therefore, in the electronic timepiece 10, a wearing determination process is executed to determine whether or not the electronic timepiece 10 is worn on the body of the user. It has become.

<Operation related to wearing judgment>
The operation related to the wearing determination of the electronic timepiece 10 will be described below.
The CPU 11 of the electronic timepiece 10 of the present embodiment executes composite determination processing including first determination processing and second determination processing in order to determine whether the own device is attached to the user's body. If it is determined in at least one of the first determination process and the second determination process that the electronic timepiece 10 is in the wearing state, the determination result of the combined determination processing as a whole is "wearing state". On the other hand, if both the first determination process and the second determination process determine that the electronic timepiece 10 is in the non-wearing state, the determination result of the combined determination processing as a whole is "non-wearing state." . Specific processing contents of the first determination process and the second determination process will be described below.

(First determination process)
In the first determination process, the CPU 11 determines, based on the detection result of the motion sensor 17, whether or not a change in the motion state of the own device according to the user's response to the notification made by the notification unit 16 has been detected. do. The CPU 11 determines that the electronic timepiece 10 is in the wearing state when it determines that a change in the exercise state of its own device according to the user's response action has been detected. For example, if the user responds to the notification by moving his/her arm to look at the electronic timepiece 10, it is determined that the electronic timepiece 10 is worn. Here, the user's response action is not necessarily limited to the action of moving the arm to look at the electronic timepiece 10, but may be any action that changes the motion state of the electronic timepiece 10 after the execution of the notification. For example, it may be a motion of simply swinging the arm.

The notification used in the first determination process may be repetitive notification that the CPU 11 causes the notification unit 16 to repeatedly execute in accordance with predetermined notification settings. For example, the notification setting No. in the notification setting data 122 in FIG. 2, it may be a repetitive notification that is repeated at intervals of 5 minutes. The CPU 11 executes the first determination process in response to each of these repetitive notifications. When the repetition cycle of the repetitive notification is the first cycle, the first determination process is repeatedly executed in the first cycle. Therefore, the composite determination process including the first determination process is also repeatedly executed in the first cycle. Here, when the repetition cycle of the pulse rate measurement process (information acquisition process) described above is the second cycle, the first cycle is preferably shorter than the second cycle. In this embodiment, the second cycle in which the pulse rate measurement process is executed is 10 minutes, and the first cycle in which the composite determination process is executed is 5 minutes. As a result, it is possible to effectively reduce the occurrence of an unnecessary pulse rate measurement process when the electronic timepiece 10 is not worn.

The notification used in the first determination process is not limited to repetitive notification, and is irregularly executed according to a process different from the first determination process (or a process different from the composite determination process). It may be a notification. The CPU 11 may execute the first determination process (therefore, the composite determination process including the first determination process) in response to such irregular notification.

(Second determination process)
In the second determination process, the CPU 11 refers to the operation history data 123 and determines whether a user operation (for example, pressing the operation button 141 or rotating the crown) is performed on the operation unit 14 during a predetermined determination period. Determine whether or not The CPU 11 determines that the electronic timepiece 10 is in the wearing state when the user operation is performed during the determination period. The determination period for the second and subsequent combined determination processes can be set within a period after the last time the combined determination process is completed. For example, the CPU 11 determines that the electronic timepiece 10 is worn when there is a history of operations on the operation unit 14 from the time when the composite determination process was last completed to the present time. However, the determination period is not limited to this, and may be a period up to the present time, which is shorter than the first period described above. The determination period in the first composite determination process is predetermined, for example, as a period having the same length as the first period or a period shorter than the first period.

(Composite judgment processing)
According to the composite determination process that combines the first determination process and the second determination process as described above, it is determined in the first determination process that the user is in the non-wearing state without responding to the notification. Also, if the user's operation is performed within the determination period, it can be determined that the device is in the wearing state in the second determination process. Further, even if no user operation is performed within the determination period and it is determined in the second determination process that the device is in the non-wearing state, if the user reacts to the notification, the first determination process is performed. can be determined to be in the worn state. Therefore, with a simple configuration including at least the motion sensor 17 and the operation unit 14, it is possible to perform attachment determination more reliably.

In the composite determination process, either the first determination process or the second determination process may be executed first. If it is determined that the electronic timepiece 10 is worn in one of the first determination process and the second determination process executed first, the The other may not be executed.
Also, at least part of the first determination process and the second determination process may be executed in parallel.

Note that if the motion state of the electronic timepiece 10 specified from the detection result by the motion sensor 17 in the composite determination process is the same as the motion state in the previous composite determination process, the composite determination process may not be executed. For example, even if the user wears the electronic timepiece 10, if the user does desk work and does not move his/her wrist for a long time, the user may not react to the notification and there may be no user operation during the determination period. It can happen. If the composite determination process is executed in such a case, it will be erroneously determined to be in the non-wearing state, but the decoding determination process is not executed if the movement state of the electronic timepiece 10 is the same as at the time of the previous composite determination process. By doing so, the occurrence of such erroneous determination can be reduced.

When it is determined in the combined determination process that the device is in the wearing state, the next execution timing of the combined determination process (that is, the next repetition notification execution timing; in other words, the next execution timing of the first determination process) is delayed. can be adjusted as follows. For example, the execution of the next composite determination process (repeated notification, first determination process) may be stopped, and the next composite determination process (repeated notification, first determination process) may be restarted. Alternatively, the execution of the compound determination process (repeated notification, first determination process) a predetermined number of times after the next time may be stopped. As a result, it is possible to suppress the frequency of the composite determination process (repeated notification), so that the annoyance of the notification can be made less noticeable. Also, power consumption for composite determination processing can be reduced.

If it is determined in the composite determination process that the device is not worn, execution of the next and subsequent pulse rate measurement processes is stopped. Note that if there is a process other than the pulse rate measurement process that is executed on the premise that the electronic timepiece 10 is worn, the execution of that process may be stopped. The processing that is executed on the premise that the electronic timepiece 10 is worn includes, for example, processing for acquiring activity information related to the user's activity state. Here, the activity information includes information related to the user's exercise state such as walking and running, information related to the sleep state, and the like. The process of acquiring activity information is one aspect of the information acquisition process.

<Operation related to cancellation and change of notification operation>
In the electronic timepiece 10 of the present embodiment, when it is detected that the user has performed a predetermined gesture when the notification unit 16 has performed notification, the notification operation is stopped in response to the gesture, or Settings related to the notification operation are changed. Here, the notification to be canceled or changed in setting may be any notification including the above-described repetitive notification and irregular notification.

Specifically, the CPU 11 of the electronic timepiece 10 determines whether or not the user has made a predetermined stop gesture during the notification based on the detection result of the motion sensor 17 . When the CPU 11 determines that the user has made the stop gesture, the CPU 11 stops the notification being executed.

Further, the CPU 11 determines whether or not the user has performed a predetermined setting change gesture based on the detection result of the motion sensor 17 when causing the notification unit 16 to perform repeated notification. When the CPU 11 determines that the user has performed the setting change gesture, the CPU 11 changes the notification setting of the notification setting data 122 and, according to the notification setting after the change, cancels the execution of the notification after the next time, or cancels the execution of the notification after the next time. Change the mode of notification to be executed. By making the setting change gesture a different gesture (distinguishable gesture) from the cancel gesture, the operation of canceling the notification in response to the cancel gesture and the operation of changing the notification setting in response to the setting change gesture are independent. can accept.

The cancel gesture and the setting change gesture are not particularly limited as long as they can be distinguished based on the detection result of the motion sensor 17 . Specifically, it may be an action of moving the arm in a circular motion, an action of vibrating the arm, or an action of reciprocating the arm. The cancel gesture and the setting change gesture are actions that can be distinguished from actions for the user to simply check the main device 10 in response to the notification (for example, an action of bringing the wrist on which the electronic watch 10 is worn close to the face). may As a result, when the user simply performs an action for checking the main device 10 in response to the notification, the notification may be stopped by recognizing it as a cancel gesture, or the notification setting may be changed by recognizing it as a setting change gesture. you can avoid it.

Alternatively, any gesture other than the setting change gesture may be set to be recognized as the abort gesture. That is, the setting change gesture may be defined in advance, and the cancel gesture may not be defined in advance, and any gesture other than the setting change gesture may be used as the cancel gesture. In this case, for example, when the user performs an operation for simply checking the main device 10 in response to the notification, the notification being executed can be stopped.
Also, any gesture including a setting change gesture may be set to be recognized as a cancel gesture. According to this, by performing the setting change gesture, it is possible to stop the notification being executed.

Also, a plurality of setting change gestures may be defined. In this case, the CPU 11 determines whether or not the user has performed any one of a plurality of different setting change gestures based on the detection result of the motion sensor 17 . When the CPU 11 determines that the user has performed one of a plurality of setting change gestures, the notification setting of the notification setting data 122 is associated in advance with the setting change gesture performed by the user. Change to content.

Specifically, the plurality of setting change gestures may include a first setting change gesture for changing the notification setting so as to stop repeated notification from the next time onward. When the CPU 11 determines that the user has performed the first setting change gesture, the CPU 11 changes the setting of "notification ON/OFF" or "repetition" in the notification setting data 122 of FIG. stop the execution of repeated notification.

Also, the plurality of setting change gestures may include a second setting change gesture for changing the notification setting so that the notification is not performed for a predetermined number of times or for a predetermined period after the next time. When the CPU 11 determines that the user has performed the second setting change gesture, the CPU 11 changes the "next notification time" in the notification setting data 122 of FIG. 4 and adjusts the execution time of the next repetitive notification. For example, when the second setting change gesture is defined as a gesture to stop m times of repetitive notification from the next time onward, the CPU 11 adds the value of "repetition interval x m" to the "next notification time". By making a change to , the repetitive notification is skipped for m times. Further, when the second setting change gesture is defined as a gesture for stopping the repeated notification for a predetermined period, the CPU 11 changes the "next notification time" by adding the length of the predetermined period. By doing so, the repeated notification is skipped for a predetermined period of time.

Also, the plurality of setting change gestures may include a third setting change gesture for changing the notification setting such that the repetition period of the notification is increased or decreased. When the CPU 11 determines that the user has performed the third setting change gesture, the CPU 11 changes the setting value of the "repetition interval" in the notification setting data 122 of FIG. . For example, the notification setting No. in FIG. 2, when the "repetition interval" is set to 5 minutes, when the user performs a third setting change gesture that is preset to increase the notification repetition period by 10 minutes, The "repeat interval" is changed to 15 minutes, and repeat notification is performed every 15 minutes thereafter.

The setting change gestures included in the plurality of setting change gestures are not limited to the above. For example, setting change gestures for changing the "notification duration" and "notification type" of the notification setting data 122 may be included.
At least one of the cancel gesture and the setting change gesture may be registered differently according to the type of notification to be executed (for example, "notification setting No." in the notification setting data 122 of FIG. 4). For example, for wake-up alerts, a large movement gesture (eg, a gesture with more movement than the default gesture) may be used as an abort gesture and/or a setting change to fully awaken the user's consciousness. It may be registered as a gesture. In addition, as in the notification used for wearing determination in the present embodiment, a small movement gesture (for example, a gesture with a smaller movement than the default gesture) is used for a notification that is sufficient if at least the user's movement can be confirmed. may be registered as an abort gesture and/or a setting change gesture. In addition, the size of the gesture is not limited, and the contents of the gesture (direction, angle, height, speed, or change amount of these, etc.) may be registered differently according to the type of notification.

<Control Procedure for Mounting Determination Processing>
Next, the control procedure by the CPU 11 for the mounting determination process will be described.
FIG. 6 is a flowchart for explaining the control procedure of the wearing determination process.
Here, in the notification setting data 122, only the notification on the system shown in FIG. I will list and explain.

When the wearing determination process is started, the CPU 11 of the electronic timepiece 10 refers to the notification setting data 122 to determine the notification setting No. It is determined whether or not it is time to execute the repetitive notification of No. 2 (step S101).

If it is determined that it is time to execute repeated notification ("YES" in step S101), the CPU 11 acquires the detection result of the motion sensor 17 and determines the motion state of the electronic timepiece 10 (step S102). In addition, the CPU 11 determines whether or not the determination result of the exercise state is different from the determination result of the previous determination (that is, the determination result of the exercise state performed last time in step S102) (step S103). When it is determined that the exercise state is different from the determination result of the previous determination ("YES" in step S103), the CPU 11 causes the notification unit 16 to perform notification (step S105). Here, the CPU 11 sets the notification setting No. of the notification setting data 122 . The notification is executed with the notification type and duration according to 2.

On the other hand, if it is determined in step S101 that it is not the time to execute repeated notification ("NO" in step S101), the CPU 11 sets the notification setting No. 1, it is determined whether or not an instruction to execute irregular notification on the system has been issued (step S104). When it is determined that the irregular notification execution instruction has not been issued ("NO" in step S104), the CPU 11 returns the process to step S101. When it is determined that an instruction to execute irregular notification has been issued ("YES" in step S104), the CPU 11 causes the notification unit 16 to perform notification (step S105). Here, the CPU 11 sets the notification setting No. of the notification setting data 122 . The notification is executed with the notification type and duration corresponding to 1.

When notification is started in step S105, the CPU 11 executes notification operation control processing, which will be described later (step S106). In the notification operation control process, the notification is stopped in response to the cancel gesture, and the notification setting is changed in response to the setting change gesture.

When the notification operation control process ends, the CPU 11 acquires the detection result of the motion sensor 17 and determines whether or not a change in the exercise state corresponding to the user's response operation to the notification executed in step S105 has been detected ( step S107). For example, the CPU 11 calculates a conversion value representing the state of exercise based on the values detected by the triaxial acceleration sensor 171, the triaxial gyro sensor 172, and the triaxial geomagnetic sensor 173. If the converted value representing the state changes by a predetermined reference value or more, it is determined that a change in exercise state has been detected. When it is determined that a change in exercise state according to the user's response action has been detected ("YES" in step S107), the CPU 11 determines that the electronic timepiece 10 is worn (step S109).

When it is determined that no change in the exercise state corresponding to the user's response motion has been detected ("NO" in step S107), the CPU 11 refers to the operation history data 123, and determines whether the user's operation has been performed during the determination period. (step S108). If it is determined that a user operation has been performed during the determination period ("YES" in step S108), the CPU 11 determines that the electronic timepiece 10 is worn (step S109). If it is determined that no user operation has been performed during the determination period ("NO" in step S108), the CPU 11 determines that the electronic timepiece 10 is not worn (step S110).

A series of processes of steps S107 to S110 correspond to the "composite determination process". Among these, steps S107, S109, and S110 correspond to "first determination processing", and steps S108, S109, and S110 correspond to "second determination processing". Steps S107 and S108 may be interchanged in order to interchange the execution order of the first determination process and the second determination process.

When it is determined in step S109 that the device is in the wearing state, the CPU 11 determines whether the determination is the first determination or whether the previous determination result is the "non-wearing state" (step S111). If it is determined that this is the first determination, or if the previous determination result is the "non-wearing state" ("YES" in step S111), the CPU 11 performs processing on the premise that it is in the wearing state, Here, pulse measurement processing is started (step S112). However, the process does not necessarily have to be started at this timing, and may be started according to an instruction from the user, for example.

When step S112 ends, or when it is determined in step S111 that this is not the first determination and the previous determination result is not the "non-wearing state" ("NO" in step S111), the CPU 11 adjusts the execution timing of the next repetitive notification (step S113). Here, the CPU 11 sets the notification setting No. of the notification setting data 122 so that, for example, the next repeated notification is skipped. The "repetition interval" time is added to the "next notification time" in 2. However, step S113 is executed only when the execution timing of the next combined judgment process is set to be delayed at the time of mounting judgment, and is omitted in other cases.

On the other hand, if it is determined in step S110 that the user is not wearing the device, the CPU 11 stops the processing on the assumption that the user is wearing the device, here the pulse measurement processing (step S114).

When step S113 or step S114 is completed, or when it is determined in step S103 that the exercise state does not differ from the determination result of the previous determination ("NO" in step S103), the CPU 11 starts the wearing determination process. It is determined whether or not an end instruction has been given (step S115). For example, the CPU 11 determines that an instruction to end the wearing determination process has been issued when a user operation to turn off the power of the electronic timepiece 10 has been performed. When it is determined that an instruction to end the attachment determination process has not been issued ("NO" in step S115), the CPU 11 returns the process to step S101. When it is determined that an instruction to end the wearing determination process has been given ("YES" in step S115), the CPU 11 ends the wearing determination process.

In step S104 of the attachment determination process, it is determined that an instruction to execute irregular notification has been issued ("YES" in step S104), and when the notification in step S105 is executed, the combined determination process is not executed. (That is, the processing of steps S107 to S115 may be omitted). In other words, the composite determination process may be performed only when repeated notification is performed in step S105.

Also, in the above description, the repeated notification on the system for the first determination process (notification setting No. 2 in FIG. 4) was exemplified as the repeated notification, but the repeated notification is not limited to this. If the notification setting data 122 includes a notification setting (for example, notification setting No. 4 in FIG. 4) related to repetitive notification by user setting, repetitive notification corresponding to the notification setting is executed in step S105, and the repetitive notification is performed in step S105. The composite determination process from step S107 onward may be executed with the notification as a trigger.

Also, as an irregular notification, the irregular notification on the system (notification setting No. 1 in FIG. 4) that is executed in conjunction with the occurrence of an event on the system was exemplified, but the irregular notification is not limited to this. . If the notification setting data 122 includes a notification setting related to irregular notification by user setting (for example, notification setting No. 3 in FIG. 4), irregular notification corresponding to the notification setting is executed in step S105, The repeated notification may be used as a trigger to execute the composite determination process from step S107 onward.

FIG. 7 is a flowchart for explaining the control procedure of the notification operation control process.
When the notification operation control process is started, the CPU 11 determines whether or not the user's stop gesture has been detected during the notification based on the detection result of the motion sensor 17 (step S201). When it is determined that a stop gesture has been detected (step S201), the CPU 11 transmits a control signal to the notification unit 16 to stop the notification being executed (step S202).

When step S202 ends, or when it is determined in step S201 that the user's stop gesture was not detected during execution of the notification ("NO" in step S201), the CPU 11 determines that the executed notification It is determined whether or not it is repeated notification (notification of notification setting No. 2 in the notification setting data 122) (step S203).

When it is determined that the executed notification is repeated notification ("YES" in step S203), the CPU 11 determines whether or not the user's first setting change gesture has been detected after the start of notification ( step S204). When it is determined that the first setting change gesture has been detected ("YES" in step S204), the CPU 11 changes the notification setting of the notification setting data 122 so as to stop execution of repeated notification from the next time onward. (step S205). Specifically, the CPU 11 changes the setting of "notification ON/OFF" or "repetition" in the notification setting data 122 of FIG. 4 to "OFF".

When it is determined that the first setting change gesture has not been detected ("NO" in step S204), the CPU 11 determines whether or not the user's second setting change gesture has been detected after the start of notification. (Step S206). When it is determined that the second setting change gesture has been detected ("YES" in step S206), the CPU 11 changes the notification setting data 122 so that repeated notification for a predetermined number of times or for a predetermined period from the next time onwards is not performed. Change notification settings. Specifically, the CPU 11 changes the "next notification time" in the notification setting data 122 of FIG. 4 to adjust the execution time of the next repetitive notification.

When it is determined that the second setting change gesture has not been detected ("NO" in step S206), the CPU 11 determines whether or not the user's third setting change gesture has been detected after the start of notification. (Step S208). When it is determined that the third setting change gesture has been detected ("YES" in step S208), the CPU 11 changes the notification setting of the notification setting data 122 so as to increase or decrease the repetition period of the repetitive notification. . Specifically, the CPU 11 changes the setting value of the "repetition interval" in the notification setting data 122 of FIG.

If it is determined that the third setting change gesture has not been detected (“NO” in step S208), or if any of steps S205, S207, and S209 has ended, or if the executed notification is repeated in step S203 If it is determined that it is not the notification (that is, the irregular notification) (“NO” in step S203), the CPU 11 terminates the notification operation control process and shifts the process to step S107 of the mounting determination process. .
In the notification operation control process, the cancel gesture and the first to third setting change gestures are one aspect of the user's reaction operation to the notification. In step S107 of the determination process, it is determined that a change in exercise state corresponding to the user's response motion has been detected.

In the above description, an example in which the notification operation control process is called in the wearing determination process has been described, but the present invention is not limited to this. may be performed separately.

Further, in the notification operation control process, the irregular notification on the system may not be canceled in response to the cancellation gesture. That is, step S203 in FIG. 7 is performed before step S201, and in step S203, when it is determined that the executed notification is not repeated notification (that is, irregular notification on the system) (in step S203 "NO"), the notification operation control process may be ended without executing steps S201 and S202.

Moreover, steps S203 to S209 may be executed while the notification is being continued. Further, if the notification is being continued when the setting change gesture is detected in any of steps S204, S206, and S208, the notification may be stopped in response to the detection of the setting change gesture.

Further, in step S205, instead of changing the settings to stop repeated notifications from the next time onward, the notification settings may be changed so as to stop execution of all subsequent notifications, including irregular notifications on the system. .

Further, in step S207, the notification setting may be changed so that all notifications including irregular notifications on the system are not performed for a predetermined period of time.

In addition, in the notification operation control, one of the processing of stopping notification in response to detection of a stop gesture (steps S201 and S202) and the processing of changing notification settings in response to detection of a setting change gesture (steps S203 to S209). may be omitted.

Next, modified examples 1 and 2 of the above embodiment will be described. In Modifications 1 and 2, differences from the above embodiment will be described, and descriptions of points common to the above embodiment will be omitted. Also, Modification 1 and Modification 2 may be combined.

<Modification 1>
In the above embodiment, wearing judgment is performed by combined judgment processing including the first judgment processing and the second judgment processing. In addition, wearing judgment using the pulse sensor 18 may be used together. The wearing determination by the pulse sensor 18 is performed based on whether or not the amount of light received from the light receiving section 182 is greater than a predetermined reference amount of light. When the electronic timepiece 10 is worn on the user's wrist, the light emitted from the light emitting section 181 is reflected by the skin and enters the light receiving section 182 . On the other hand, when the electronic timepiece 10 is removed from the user's wrist, the light emitted from the light emitting section 181 is diffused without being reflected on the user's skin, and hardly returns to the light receiving section 182 . Therefore, when the electronic timepiece 10 is not worn, the amount of light received by the light receiving section 182 is significantly lower than when the electronic timepiece 10 is worn. Therefore, whether or not the electronic timepiece 10 is worn can be determined based on whether or not the amount of light received by the light receiving section 182 is greater than the reference amount of light. The reference amount of light is set to a value between the amount of light received when the electronic timepiece 10 is worn by the user and the amount of light received when the electronic timepiece 10 is not worn by the user. By using both the wearing determination using the pulse sensor 18 and the combined wearing determination of the above-described embodiment, it is possible to improve the accuracy of detecting the wearing state.

<Modification 2>
In the above embodiment, the attachment determination is performed by the combined determination process including the first determination process and the second determination process, but the second determination process may be omitted in the combined determination process. That is, the wearing determination may be performed only by the first determination processing.

<effect>
As described above, the electronic timepiece 10 as an electronic device according to the present embodiment is used by being worn on the user's body. and a CPU 11 as a processing unit. The CPU 11 determines that the own device is attached to the user's body when detecting a change in the exercise state of the own device according to the user's response to the notification based on the detection result of the motion sensor 17. 1 is executed. According to this, with a simple configuration that includes at least the motion sensor 17 and the operation unit 14, it is possible to perform attachment determination based on the user's reaction motion. Therefore, attachment determination can be performed more reliably while suppressing complication of the device configuration.

Further, the CPU 11 executes a composite determination process including a first determination process and a second determination process. is attached to the user's body. According to this, with a simple configuration that includes at least the motion sensor 17 and the operation unit 14, it is possible to perform attachment determination that comprehensively reflects the user's reaction motion and the user's operation history. That is, even if it is determined in the first determination process that the user does not perform any reaction to the notification and is in the non-wearing state, if the user operates within the determination period, the wearing state is determined in the second determination process. state. Further, even if no user operation is performed within the determination period and it is determined in the second determination process that the device is in the non-wearing state, if the user reacts to the notification, the first determination process is performed. can be determined to be in the worn state. Therefore, attachment determination can be performed more reliably while suppressing complication of the device configuration.

In addition, in the composite determination process, the CPU 11 executes one of the first determination process and the second determination process after the other is completed, and executes the first determination process and the second determination process first. On the other hand, when it is determined that the own device is attached to the user's body, the other of the first determination processing and the second determination processing is not executed. As a result, it is possible to perform the wearing determination with the minimum necessary processing. Also, power consumption for composite determination processing can be reduced.

In addition, the CPU 11 repeatedly executes the composite determination process, and the determination period for the second and subsequent composite determination processes is determined within a period after the final completion of the composite determination process. Accordingly, when the user operation is performed after the last completed composite determination process, it can be determined that the device is in the wearing state.

In addition, the CPU 11 determines whether or not the user has made a predetermined stop gesture as a response action during execution of the notification based on the detection result of the motion sensor 17. When it is determined that the user has made a stop gesture, , to stop the notification in progress. As a result, the user can stop the notification by an intuitive and simple method of making a stop gesture without directly operating the operation unit 14 of the electronic timepiece 10 . Therefore, the intended operation can be easily performed at an appropriate time.

The notification includes repetitive notification that the processing unit causes the notification unit 16 to repeatedly perform according to predetermined notification settings, and the CPU 11 executes the first determination process according to each repetitive notification. Accordingly, it is possible to perform wearing determination periodically.

Further, the CPU 11 determines whether or not the user has performed a predetermined setting change gesture as a response operation based on the detection result of the motion sensor 17. When it is determined that the user has performed the setting change gesture, the notification setting is performed. is changed, and according to the changed notification setting, execution of the notification after the next time is stopped, or the form of the notification to be executed after the next time is changed. As a result, the user can change the settings related to subsequent notifications by an intuitive and simple method of making a setting change gesture without directly operating the operation unit 14 of the electronic timepiece 10 . Therefore, the intended operation can be easily performed at an appropriate time.

Further, the notification includes irregular notification executed irregularly according to a process different from the first determination process, and the CPU 11 executes the first determination process according to the irregular notification. As a result, it is possible to use arbitrary irregular notifications for purposes other than wearing determination for wearing determination. Therefore, it is possible to perform the wearing determination without making the user aware of the wearing determination.

Further, the CPU 11 repeatedly executes the first determination process at a predetermined cycle, and when it is determined in the first determination process that the own device is attached to the user's body, at least the next combined determination process is executed. Abort execution. As a result, it is possible to suppress the frequency of the composite determination process (repeated notification), so that the annoyance of the notification can be made less noticeable. Also, power consumption for composite determination processing can be reduced.

Further, the CPU 11 repeatedly executes information acquisition processing for acquiring user's biometric information or activity information related to the user's activity state, and in the first determination processing, it is determined that the own device is attached to the user's body. If not, execution of the information acquisition process after the next time is canceled. As a result, it is possible to reduce the occurrence of a problem that unnecessary information acquisition processing (for example, pulse rate measurement processing) is executed when the electronic timepiece 10 is not worn.

Further, the CPU 11 repeatedly executes the first determination process in a first period, and repeatedly executes the information acquisition process in a second period, and the first period is shorter than the second period. As a result, when the electronic timepiece 10 is not worn, the information acquisition process can be stopped in a timely manner. Therefore, it is possible to more effectively reduce the occurrence of a problem that unnecessary information acquisition processing is executed.

In addition, the wearing determination method executed by the CPU 11 as a computer of the electronic timepiece 10 according to the present embodiment is based on the detection result of the motion sensor 17, and changes in the exercise state of the own device according to the user's response to the notification. is detected, a first determination process is performed to determine that the own device is attached to the user's body. According to this, with a simple configuration that includes at least the motion sensor 17 and the operation unit 14, it is possible to perform attachment determination based on the user's reaction motion. Therefore, attachment determination can be performed more reliably while suppressing complication of the device configuration.

In addition, the program 121 according to the present embodiment causes the CPU 11 as a computer of the electronic timepiece 10 to detect changes in the exercise state of the own device according to the user's response to the notification based on the detection result of the motion sensor 17. In this case, a first determination process is executed to determine that the own device is attached to the user's body. According to this, with a simple configuration that includes at least the motion sensor 17 and the operation unit 14, it is possible to perform attachment determination based on the user's reaction motion. Therefore, attachment determination can be performed more reliably while suppressing complication of the device configuration.
