As shown in FIG. In the following description, the first LED 21a, the second LED 21b, and the third LED 21c are abbreviated as LEDs 21a, 21b, and 21c as necessary. Pulse wave sensor 20, mainly while the electronic device 1 is worn on the user's wrist, irradiates the user's wrist with detection light from each LED 21a, 21b, 21c, and from the user's wrist in a state where the detection light is irradiated The reflected light is received by the photodiode 22, a detection signal corresponding to the amount of light received by the photodiode 22 is supplied to the CPU 11 as pulse wave data, and the CPU 11 measures the pulse rate (heart rate) by a known method. make it possible. In this embodiment, the detection light emitted by each of the LEDs 21a, 21b, and 21c is green light that is easily absorbed by hemoglobin in blood, such as visible light with a wavelength of 520 nm to 530 nm.

In the electronic device 1 of this embodiment configured as described above, a plurality of operation modes are provided for each application, and the user can selectively set them. While the electronic device 1 is operating in one of the operation modes, the CPU 11 executes various processes according to the operation mode being set based on the programs stored in the ROM 12 . As a result, while the electronic device 1 is worn on the arm of the user, various information including exercise information and biological information of the user is acquired using the acceleration sensor 18, the magnetic sensor 19, and the pulse wave sensor 20. It is recorded in the RAM 13. Also, part of the information is displayed on the display device 15 . In addition, the electronic device 1 is provided with an operation mode in which the user's heart rate is measured at regular intervals (for example, every minute), and the measurement results, that is, the user's biometric information are recorded and displayed sequentially.

Further, during operation of the electronic device 1, the CPU 11 constantly determines whether or not the electronic device 1 is worn on the user's arm. This determination is performed using the acceleration sensor 18 described above. More specifically, transition data of the acceleration of the device main body 2 when the electronic device 1 is worn on the arm and when the device is removed from the arm, and transition data of the acceleration of the device main body 2 during other uses. are obtained, and a discriminator (for example, a support vector machine, a neural network, etc.) is generated by supervised machine learning using the obtained acceleration transition data. Then, the discriminator can discriminate whether or not the input acceleration transition data of the device main body 2 is the acceleration transition data when the electronic device 1 is attached to the arm or removed from the arm. So, it is machine learning.

Then, during the operation of the electronic device 1, the CPU 11 repeatedly executes the process shown in FIG. 3 at the operation timing of the determined cycle in parallel with the above process. That is, FIG. 3 is a flowchart mainly showing LED control processing related to light emission of the LEDs 21a, 21b, and 21c of the pulse wave sensor 20 by the CPU 11. As shown in FIG.

In this process, the CPU 11 first determines whether or not the electronic device 1 is worn on the user's arm (step SA1). This determination is performed based on the results of determination operations that are routinely performed as described above. That is, it is determined whether or not the electronic device 1 was in the wearing state in the previous determination result. Then, if the electronic device 1 is in the worn state (step SA1: YES), the CPU 11 determines whether or not it is time to measure the heart rate (step SA2). The heartbeat measurement timing is the execution timing of heartbeat measurement at regular time intervals (for example, every minute). Here, if it is not the heart rate measurement timing (step SA2: YES), the CPU 11 terminates the process.

On the other hand, if it is the heartbeat measurement timing (step SA2: YES), the CPU 11 causes the LEDs 21a, 21b, and 21c to emit light for a predetermined period of time in a pattern for detecting pulse waves (step SA3). , terminate the process. At step SA3, the CPU 11 causes the LEDs 21a, 21b, and 21c to emit light for a predetermined period of time at a predetermined brightness suitable for obtaining a pulse wave. In addition, while each LED 21a, 21b, 21c is emitting light, the reflected light from the user's wrist is received by the photodiode 22, and the CPU 11 receives the detection signal from the pulse wave sensor 20 according to the received light amount. Acquired as pulse wave data. Then, the heart rate is calculated based on the pulse wave data, stored in the RAM 13, and displayed on the display device 15. FIG.

On the other hand, if the electronic device 1 is not in the attached state (step SA1: NO), the CPU 11 determines whether or not the electronic device 1 is being charged by determining the operation state of the power supply unit 23 (step SA4). . Then, if the electronic device 1 is being charged (step SA4: YES), the CPU 11 lights the respective LEDs 21a, 21b, and 21c in a charging notification pattern indicating that the electronic device 1 is being charged (step SA5). ) and terminate the process. At step SA5, the CPU 11 causes the LEDs 21a, 21b, and 21c to start emitting light in a light emission pattern for notifying that charging is in progress. In this case, the light emission pattern of the LEDs 21a, 21b, and 21c is lighting with a luminance sufficient to notify that the electronic device 1 is being charged. , 21c.

If the electronic device 1 is not in the mounted state (step SA1: NO) and is not being charged (step SA4: NO), the CPU 11 turns off the LEDs 21a, 21b, and 21c (step SA5), and terminates the process. . In other words, the CPU 11 terminates the light emission of the LEDs 21a, 21b, and 21c when they were lit before this time, and maintains the state when the LEDs 21a, 21b, and 21c are not lit.

As described above, in the electronic device 1 of the present embodiment, the CPU 11 lights the LEDs 21a, 21b, and 21c of the pulse wave sensor 20 when the electronic device 1 is in the charging state. Thereby, each LED21a, 21b, 21c can be made to function as an indicator which alert|reports a charge state. Therefore, in the electronic device 1, there is no need to provide a dedicated LED for reporting the state of charge, the size of the circuit board can be reduced, and the degree of freedom in design can be increased. At the same time, since the number of man-hours for mounting electronic components on the circuit board is reduced, the cost of the electronic device 1 can be reduced. Moreover, since the brightness of each of the LEDs 21a, 21b, and 21c when functioning as an indicator is much lower than that when measuring the heartbeat, power consumption is wasted when the charging state is displayed on the display device 15, for example. There is no Therefore, the notification function can be ensured in the electronic device 1 without causing an increase in power consumption associated with the notification operation of notifying the state of charge.

Next, in the electronic device 1, a notification process executed by the CPU 11 at a specific timing when notification to the user is required will be described with reference to the flowchart of FIG. This notification process is a process of temporarily notifying at a specific timing, and a specific type of notification is, for example, when the electronic device 1 is connected (paired) with a smartphone by BLE, an incoming call in the smartphone and notification of reception of a message in SNS (Social Networking Service).

At the specific timing, the CPU 11 first determines whether or not the electronic device 1 is being charged by determining the operating state of the power supply unit 23. If the electronic device 1 is being charged (step SB1: YES), the display The screen of the device 15, that is, the display section 3 is caused to display character information, graphics, etc. indicating the type of notification (step SB2), and the process is terminated. This allows the user to be notified of incoming calls, messages, and the like. When the battery is being charged as described above, the LEDs 21a, 21b, and 21c of the pulse wave sensor 20 are lit in the charging notification pattern according to the LED control process described above.

On the other hand, if the electronic device 1 is not charging (step SB1: NO), the CPU 11 further does not turn on the LEDs 21a, 21b, and 21c of the pulse wave sensor 20, based on the amount of light received by the photodiode 22, It is checked whether or not the electronic device 1 is worn on the user's wrist (step SB3). At this time, if the amount of light received by the photodiode 22 is equal to or less than the threshold value, the CPU 11 judges that the photodiode 22 hardly receives external light because the outside light is blocked by the user's wrist, and that the electronic device 1 is attached. If the amount of received light exceeds the threshold value, it is determined that the external light is received by the photodiode 22 without being blocked by the wrist, and that the electronic device 1 is not worn. In other words, it is determined again whether or not the electronic device 1 is in the wearing state based on information different from that at the time of determination which is routinely performed as described above. Then, when it is determined that the electronic device 1 is in the wearing state (step SB3: YES), even if an attempt is made to turn on the LEDs 21a, 21b, and 21c to indicate an incoming call or message reception, the user will not notice it because it is blocked by the wrist. Therefore, the CPU 11 causes the display device 15 (display unit 3) to display character information, graphics, etc. indicating the type of notification (step SB2), as in the case where the electronic device 1 is being charged, and terminates the process. .

On the other hand, when the CPU 11 determines that the electronic device 1 is not being worn (step SB3: NO), first, according to the type of notification to the user, the LEDs 21a, 21b, and 21c of the pulse wave sensor 20 emit light patterns in advance. Determine (step SB4). The light emission pattern determined here is one of a plurality of light emission patterns prepared in advance, and is a pattern predetermined corresponding to a plurality of types of notification. The light emission pattern is, for example, simultaneous light emission or simultaneous blinking of the LEDs 21a, 21b, and 21c, or sequential light emission in a predetermined order or at random. Note that the correspondence between the type of notification and the light emission pattern does not need to be one-to-one, and one light emission pattern may correspond to a plurality of types of notification.

Then, the CPU 11 causes the LEDs 21a, 21b, and 21c to emit light according to the light emission pattern determined here (step SB5). That is, the LEDs 21a, 21b, and 21c start to emit light in a specific light emission pattern. The brightness of each of the LEDs 21a, 21b, and 21c at this time is equal to or higher than the brightness of the detection pattern for acquiring the pulse wave during heart rate measurement. As a result, even when the user is not wearing the electronic device 1, that is, when the user is not paying attention to the display unit 3, the high-intensity light emitted by the LEDs 21a, 21b, and 21c can be used to receive a call or receive a message. Reception and the like can be notified.

After that, the CPU 11 waits until the user performs an operation to stop notification, for example, an operation of the plurality of button switches 4, 5, 6 or a touch operation on the display unit 3 (step SB6: NO). The light emission of the LEDs 21a, 21b, and 21c is continued, and when the notification stop operation is performed (step SB6: YES), the light emission of the LEDs 21a, 21b, and 21c is stopped (step SB7), and the process ends.

As described above, in the electronic device 1 of the present embodiment, when performing temporary notification at a specific timing, the CPU 11 causes the LEDs 21a, 21b, and 21c of the pulse wave sensor 20 to emit light, Even in a situation where the user does not pay attention to the display unit 3, the notification can be performed more reliably. Therefore, it is possible to avoid with a high probability a situation in which power is wasted due to the notification operation, as in the case where the display device 15 provides a temporary notification at a specific timing. Therefore, the notification function can be ensured in the electronic device 1 without causing an increase in power consumption associated with a temporary notification operation at a specific timing.

Further, in the electronic device 1, temporary notification by light emission of the LEDs 21a, 21b, and 21c of the pulse wave sensor 20 is performed under the condition that the electronic device 1 is not worn by the user. Therefore, unnecessary notification operations in the non-wearing state can be eliminated.

In addition, in the electronic device 1, the light emission pattern of each of the LEDs 21a, 21b, and 21c during the notification operation is a specific light emission pattern that is determined corresponding to the type of notification. can inform the specific type of notification.

In addition, in this embodiment, although the case where the luminescent color of each LED21a, 21b, 21c was green was described, not only this but the luminescent color of each LED21a, 21b, 21c may be red. Further, each of the LEDs 21a, 21b, and 21c may be of two types, an LED emitting green light and an LED emitting red light. In that case, the LED that emits light for the temporary notification is an LED with a luminescent color determined according to the type of notification, so that the type of notification can be identified by the user by the luminescent color. good too.

Further, when the LEDs 21a, 21b, and 21c are caused to emit light for a temporary notification, the driving current is changed or the duty ratio is changed to perform duty driving, so that the luminance thereof can be changed according to the inclination of the electronic device 1. , may vary according to the surrounding environment. That is, when the electronic device 1 is in the non-mounted state, the electronic device 1 is often placed at an arbitrary location. In this case, the greater the inclination of the electronic device 1 with respect to the horizontal plane, that is, the closer the optical axis of the light emitted by the LEDs 21a, 21b, and 21c is to the vertical, the more difficult it is for the user to recognize the light emitted by the LEDs 21a, 21b, and 21c. Therefore, when the LEDs 21a, 21b, and 21c emit light for temporary notification, the tilt of the electronic device 1 with respect to the horizontal plane is detected in advance using the acceleration sensor 18 or the like. By setting the brightness of each of the LEDs 21a, 21b, and 21c high, the light emitted from each of the LEDs 21a, 21b, and 21c can be easily recognized by the user.

Moreover, when the surroundings of the electronic device 1 are dark, even if the brightness of each of the LEDs 21a, 21b, and 21c is low, the light emitted by them can be easily recognized by the user. Therefore, for example, the brightness of the surroundings is checked based on the amount of external light received by the photodiode 22, and the darker the surroundings of the electronic device 1, the lower the brightness of each of the LEDs 21a, 21b, and 21c. It is possible to reduce the power consumption associated with such notification.

Also, here, the electronic device 1 in which each of the LEDs 21a, 21b, and 21c constitutes the pulse wave sensor 20 together with the photodiode 22, that is, an optical sensor that acquires the biological information of the user has been described. However, the present invention is not limited to this, and can be applied to any electronic device as long as it has a light-emitting element such as an LED that emits light for information acquisition. In that case, the number of light-emitting elements such as LEDs, the shape of the electronic device, and the application of the electronic device are also arbitrary. The present invention can also be applied to a barcode (two-dimensional code) reader used for reading barcodes (two-dimensional code), for example.
