For example, an electronic device (e.g. a smart phone) includes communication functions as well as functions such as a sound reproduction device, an imaging device, or an electronic notebook, and a wider variety of functions can be implemented on the smart phone by installing additional applications. It can be. In addition to executing installed applications or stored functions, electronic devices can receive various information in real time by connecting to servers or other electronic devices in a wired or wireless manner.

In response to these user demands, electronic devices that can be carried and used while worn on the body (hereinafter referred to as 'wearable electronic devices'), similar to wristwatches or glasses, have been commercialized. Before wristwatch-type or glasses-type electronic devices, wearable electronic devices such as earphones or hands-free sets, for example, sound devices, have provided an environment in which other electronic devices such as smart phones can be used more conveniently. As short-range wireless communication such as Bluetooth becomes more common, wearable electronic devices such as earphones or hands-free sets can transmit/receive sound signals through wireless communication with other electronic devices while worn on the user's body (e.g. ears). there is.

The wearable electronic device may process the main touch signal and the auxiliary touch signal to determine validity of the main touch signal detected by the electronic device.

The main touch signal in the wearable electronic device is used to control the electronic device so that the electronic device can perform an operation intended by the user. For example, when a single touch is made by the user on a certain area of the electronic device, It performs a function of turning media on or off, or turning active noise cancellation (ANC) on or off when a user long touches a certain area of the electronic device.

The auxiliary touch signal of the wearable electronic device refers to a situation in which the user controls the electronic device by touching a certain area when the user does not touch a certain area of the electronic device to perform the intended operation. To prevent this, the electronic device is mounted in a certain area where the user's finger can reach, and when the auxiliary touch signal is generated, the main touch signal is not generated. For example, when the wearable electronic device (e.g., earbuds) is touched or re-worn in order to fit the wearable electronic device on the ear, when the auxiliary touch signal is generated, the main touch signal is generated.

Referring to FIG. 12, in the second operation operation, the processor 520 determines whether the second debounce period of the auxiliary touch signal is less than or equal to the third critical period (1200ms) or the debounce of the auxiliary touch signal If at least a portion of the section is not included in at least one of the plurality of detection sections, the main touch signal is confirmed to be valid, and a long touch event ( 771) can occur.

According to one embodiment, if the main touch signal is invalidated in the second calculation operation, the processor 520 may perform a third calculation operation to additionally confirm the validity of the main touch signal.

According to one embodiment, the processor 520 invalidates the main touch signal corresponding to the single touch signal based on the first debounce period and the auxiliary touch detection period of the auxiliary touch signal in the second operation operation. In one case, in the third operation operation, the absolute time difference between the operation start point of the main touch signal and the operation start point of the auxiliary touch signal, and the operation release point of the main touch signal and the operation release time of the auxiliary touch signal If the sum of the absolute time differences between viewpoints is greater than the threshold time (80 ms), the main touch signal can be invalidated. The processor 520 determines that the main touch signal is valid if the sum of the absolute value time differences is less than or equal to the threshold time (80 ms), and after a first predetermined time (300 ms) from the time of release of the main touch signal. A single touch event can be generated.

According to one embodiment, in the third operation operation, when the main touch signal corresponding to the single touch signal is invalidated, the processor 520 determines the first constant value from the time of canceling the operation of the invalidated main touch signal. An arbitrary section can be set by extending the first debounce section of the auxiliary touch signal by a time period (e.g., 300 ms). Even if the electrode signal of the auxiliary touch sensor is actually detected as 0diff, the processor 520 considers that the auxiliary touch sensor has occurred in the arbitrary section and invalidates the main touch signal received after the invalidated main touch signal. You can.

The sum of (CHO Time) and the absolute value time difference (693) (CH1 Time) between the operation release point (613) of the main touch signal and the action release point (633) of the auxiliary touch signal is more than the threshold time (80 ms) If (e.g. CH0+CH1 Time 80ms), the main touch signal (a1) is treated as invalid, and if the sum of the absolute value time differences is less than the threshold time (80ms) (e.g. CH0 + CH1 Time < 80ms), the main touch signal is made valid. After confirmation, a single touch event 671 can be generated after a first predetermined time (300 ms) from the time 613 of the main touch signal release. The processor 520 determines that the sum of the absolute value time differences 693 (CH1 Time) is greater than or equal to the threshold time (80ms) (e.g. CH0+CH1 Time). 80 ms), if the main touch signal (a1) is invalidated, the first debounce section of the auxiliary touch signal is By extending, an arbitrary extension section 637 can be set. The processor 520 may consider that an auxiliary touch sensor has occurred in the arbitrary extended section and invalidate the main touch signal received after the invalidated main touch signal.

According to one embodiment, the processor 520 invalidates the main touch signal corresponding to the long touch signal based on the second debounce section of the auxiliary touch signal and a plurality of detection sections in the second operation operation. In one case, in the third operation operation, the operation start point of the auxiliary touch signal occurs in the first section or the second section among the plurality of detection sections and the auxiliary touch signal occurs in the third section among the plurality of detection sections. If it is maintained until the section, the main touch signal can be processed effectively to generate a long touch event.

According to one embodiment, in the third operation operation, the processor 520 determines that the operation start point of the auxiliary touch signal occurs before the first section among the plurality of detection sections, and the auxiliary touch signal If the operation release point occurs in any one of the first section, the second section, or the third section, or the operation start time of the auxiliary touch signal occurs in the second section and the auxiliary touch signal If the operation release point occurs in the third section, the main touch signal may be processed as invalid.

According to one embodiment, in the third operation operation, when the main touch signal corresponding to the long touch signal is invalidated, the processor 520 performs a first preset operation from the time of canceling the operation of the invalidated main touch signal. By setting a random auxiliary touch signal to occur up to a period of time (e.g., 300 ms), the main touch signal received after the invalidated main touch signal can be invalidated. The processor 520 limits the number of invalidated main touch signals corresponding to long touch signals received after the invalidated main touch signal to a certain number (e.g., 2), and then continuously receives the invalidated main touch signals. A long touch event can be generated by validly processing the main touch signal. For example, the processor 520 invalidates the main touch signal corresponding to the two long touch signals received after the invalidated main touch signal in the fourth section 753 of 900 ms in FIG. 12, Afterwards, the main touch signal received continuously can be effectively processed to generate a long touch event.

For example, the threshold (th) for the touch sensitivity may be a pre-specified or pre-set capacitance change amount. For example, when the amount of capacitance change generated or formed due to an external input (e.g., user input and/or touch input) input to the auxiliary touch sensor 341 is greater than or equal to a predetermined or preset capacitance change amount, the auxiliary touch It may be determined that the touch sensitivity measured by the sensor 341 is greater than or equal to the threshold value (th). According to one embodiment, data regarding the pre-specified or pre-set capacitance change amount for the threshold th is stored in a memory (e.g., memory 130 in FIG. 1 and/or memory 530 in FIG. 10). You can.

According to one embodiment, the predetermined or preset capacitance change amount with respect to the threshold value (th) may be designed in various ways depending on the material and/or shape of the housing 322.

According to one embodiment, even when an external touch is detected to be applied to the main touch sensor 332, if the touch sensitivity detected by the auxiliary touch sensor 341 is greater than the threshold (th), the processor The operating state of the device can be maintained. In some embodiments, when the auxiliary touch sensor 341 is provided with a plurality of touch sensors (e.g., a first auxiliary touch sensor 342 and a second auxiliary touch sensor 344, a plurality of auxiliary touch sensors 341 If the touch sensitivity measured by some of the sensors (e.g., the first auxiliary touch sensor 342 or the second auxiliary touch sensor 344) is greater than or equal to the threshold (th), the processor may maintain the operating state of the wearable electronic device. Additionally, in some embodiments, the processor may maintain the operating state of the wearable electronic device only when the touch sensitivity of all of the plurality of auxiliary touch sensors 341 is measured to be greater than or equal to the threshold value (th).

Referring to FIG. 14, a processor (e.g., processor 120 of FIG. 1 and/or processor 520 of FIG. 10) considers the waveform of touch information measured by the auxiliary touch sensor 341 to create a wearable electronic device ( Example: The operating state of the wearable electronic device 300 of FIGS. 2 to 4 and/or the wearable electronic device 501 of FIG. 10 may be maintained.

At this time, the touch information measured by the main touch sensor 332 may have a peak or pulse waveform. For example, the processor may change the operating state of the wearable electronic device based on touch information having a peak or pulse waveform.

According to one embodiment, when the user touches at least a portion of the second touch area 326 to adjust the position of the wearable electronic device, the user may maintain the state of holding the wearable electronic device for a relatively long time. there is. At this time, the touch information acquired through the auxiliary touch sensor 341 is a waveform that has a touch sensitivity above the threshold (e.g., the first threshold (1th)) and is maintained for more than the threshold time (e.g., the threshold time (Tth)). You can have Alternatively, it may have a touch sensitivity within a threshold range (e.g., threshold range (Rth)) and a waveform maintained over a threshold time (e.g., threshold time (Tth)). For example, the threshold range (eg, threshold range (Rth)) may be a range between a first threshold (1th) and a second threshold (2th). In one embodiment, the second threshold (2th) may be set larger than the first threshold (1th).

In one embodiment, the processor determines that the touch sensitivity measured by the auxiliary touch sensor 341 is greater than or equal to a threshold (e.g., first threshold (1th)) and the touch duration is greater than or equal to a threshold time (e.g., threshold time (Tth)). ) The operating state of the wearable electronic device 300 can be maintained based on the touch information maintained as above.

It can be judged as being in a gripped state. In this case, the processor can maintain the operating state of the wearable electronic device.

FIGS. 15A to 15D are graphs 1500a to 1500d for explaining a first operation operation for processing the validity or invalidity of a main touch signal in a wearable electronic device according to an example.

As shown in FIG. 15A, in a structure in which components and wiring inevitably interfere due to the miniaturized design of general wearable electronic devices (e.g., earbuds), the sensitivity difference (diff) of the electrode signal of the auxiliary touch sensor is You can see that there is a significant difference after the call connection is terminated. The left waveform in FIG. 8A is a situation in which the auxiliary touch sensor is affected by the microphone signal wiring, and when a microphone-related operation occurs, the electrode signal of the auxiliary touch electrode is generated even if the user is not in contact with the position of the auxiliary touch sensor. It can be seen that the sensitivity difference (diff) continues to fluctuate dramatically, and the waveform of the auxiliary touch signal stabilizes from the time the call ends. In the method of determining invalidation of the main touch signal based on whether or not the auxiliary touch signal is generated, since the auxiliary touch signal is continuously generated in a situation in which the user does not make contact, the user touches the main touch signal to perform the number of actions. Even if the area is touched, the wearable electronic device (e.g., earbud) may not respond to the touch. Alternatively, while listening to music, the user touches the main touch sensor of the wearable electronic device twice to change the song, and the song is recognized as a single touch to play or stop, or touches the main touch sensor three times to move to the previous song. I tried to move on to the song, but it was recognized as a double touch and I could move on to the next song.

As shown in FIG. 15b, when the user performs exactly four single touches on the main touch sensor of a general wearable electronic device (e.g., an earbud), only two single touches occur, and the remaining two times are performed by the auxiliary touch sensor. Single touch is invalidated. In FIG. 15b, TSP1, one of the signals of the auxiliary touch sensors (electrodes), fluctuates at a diff level of 100 or more and fluctuates at a high level even when the main touch signal occurs, so auxiliary touch When the sensor's debounce period exceeds the threshold, the main touch signal is invalidated.

As shown in FIG. 15C, the overall level of the auxiliary touch signal can be lowered by applying an average value to the value of the auxiliary touch signal through the first calculation operation in the wearable electronic device according to the present disclosure. For example, if the auxiliary touch signal is "1,1,1,1,1,20,20,1,1,...", the average value of the previous four is "1,1,1,1,1 ,6,11,11,6,..", you can first alleviate signals that can rise high in a short period of time. As shown in FIG. 15C, as the noise level decreases, sensitivity decreases and delays occur, but through the second association operation and the third operation operation, the section defined in the first operation operation (e.g., the debounce section of the main touch signal and the secondary operation operation) It is possible to distinguish between noise signals and biological signals by checking conditions based on the debounce section of the touch signal. In one embodiment of the present disclosure, the auxiliary touch signal debounce period is set to 80ms to determine the noise signal and process the validity of the main touch signal.

As shown in FIG. 15D, through various log collection in the wearable electronic device according to the present disclosure, the noise level is lowered in the first operation operation and an appropriate section is set from the start time of the operation of the auxiliary touch signal to the time of release of the operation of the auxiliary touch signal. Thus, noise signals and biological signals can be distinguished.

FIGS. 16A to 16H are diagrams 1600a to 1600h for explaining an operation of invalidating a single touch signal in a wearable electronic device according to an embodiment.

FIG. 16A shows a case where the main touch sensor and the auxiliary touch sensor are touched at a similar moment, and the wearable electronic device (e.g., the wearable electronic device 501 of FIG. 10) performs the first arithmetic operation to the second associative operation. Through, in the first auxiliary touch detection section 651 from the start time of the operation of the main touch signal 611 to the time 613 of the operation release of the main touch signal until after the first predetermined time (300 ms), the second critical section Since the first debounce section 635 of the auxiliary touch signal (b1) of (e.g., 80 ms) or more is included in the first auxiliary touch detection section 651, the main touch signal (a1) corresponding to the single touch signal is invalidated. It can be processed with .

Through, in the first auxiliary touch detection section 651 from the start time of the operation of the main touch signal 611 to the time 613 of the operation release of the main touch signal until after the first predetermined time (300 ms), the second critical section Since the first debounce section 635 of the auxiliary touch signal (b1) of (e.g., 80 ms) or more is partially included in the first auxiliary touch detection section 651, the main touch signal (a1) corresponding to the single touch signal It can be treated as invalid.

FIG. 16C shows a case where the main touch sensor is touched after the auxiliary touch sensor is touched, and the wearable electronic device (e.g., the wearable electronic device 501 of FIG. 10) performs the first arithmetic operation to the second associative operation. Through, in the first auxiliary touch detection period 651 from the start time of the operation of the second main touch signal 611 to the time 613 of the operation release of the main touch signal until after the first predetermined time (300 ms), the second Since the first debounce section 635 of the auxiliary touch signal (b1), which is longer than the threshold section (e.g., 80 ms), is partially included in the first auxiliary touch detection section 651, the main touch signal (a1) corresponding to the single touch signal ) can be treated as invalid.

FIG. 16D shows a case where the touch of the auxiliary touch sensor is maintained longer than the touch of the main touch sensor, and the wearable electronic device (e.g., the wearable electronic device 501 of FIG. 10) performs the first to second calculation operations. Through an associative operation, in the first auxiliary touch detection section 651 from the start point of operation of the main touch signal (611) to the time of release of the main touch signal (613) until after the first predetermined time (300 ms), the second Since the first debounce section 635 of the auxiliary touch signal (b1), which is longer than the threshold section (e.g., 80 ms), is partially included in the first auxiliary touch detection section 651, the main touch signal (a1) corresponding to the single touch signal ) can be treated as invalid. In addition, through the third operation, the wearable electronic device calculates the absolute value time difference (CH0) between the operation start point of the main touch signal (611) and the operation start point of the auxiliary touch signal (631) and the operation of the main touch signal. Since the sum (80 ms) of the absolute value time difference (CH1) between the release time (613) and the operation release point (633) of the auxiliary touch signal is more than the threshold time (80 ms) (CH0 + CH1 Time 0 ms), it corresponds to a single touch signal. The main touch signal can be invalidated.

FIG. 16E shows a case where a touch is generated on the main touch sensor while the touch of the auxiliary touch sensor is maintained, and the wearable electronic device (e.g., the wearable electronic device 501 of FIG. 10) performs the first operation operation to the first operation operation. Through the second association operation, the second predetermined time (e.g., 50 ms) before the start of operation of the main touch signal (611) to the third predetermined time (250 ms) from the time of release of the main touch signal (613). 2 In the auxiliary touch detection period, the first debounce period 635 of the auxiliary touch signal (b1), which is longer than the second critical period (e.g., 80 ms), is partially included in the second auxiliary touch detection period 653, so that single touch The main touch signal (a1) corresponding to the signal may be processed as invalid.

FIG. 16F shows a case where the main touch area is touched after a touch occurs on the auxiliary touch sensor, and the wearable electronic device (e.g., the wearable electronic device 501 of FIG. 10) performs the first to second calculation operations. Through an associative action, the second assistant is provided from a second predetermined time (e.g., 50 ms) before the start of operation of the main touch signal (611) to a third predetermined time (250 ms) from the time of release of the main touch signal (613). In the touch detection period, the first debounce period 635a of the auxiliary touch signal b1 that is longer than the second critical period (e.g., 80 ms) and extends the first constant time (300 ms) is the second auxiliary touch detection period ( 653), the main touch signal (a1) corresponding to the single touch signal can be treated as invalid.

FIG. 16G shows a case where the auxiliary touch sensor is touched after the main touch sensor has been touched, and the wearable electronic device (e.g., the wearable electronic device 501 of FIG. 10) performs the first arithmetic operation to the second associative operation. Detection of the second auxiliary touch from a second predetermined time (e.g., 50 ms) before the start of operation of the main touch signal (611) to a third predetermined time (250 ms) from the time of release of the main touch signal (613). In the section, the first debounce section 635 of the auxiliary touch signal (b1), which is longer than the second critical section (e.g., 80 ms), is partially included in the second auxiliary touch detection section 653, corresponding to the single touch signal. The main touch signal (a1) can be processed as invalid. However, the wearable electronic device (e.g., the wearable electronic device 501 in FIG. 10) operates from the time of release of the main touch signal (613) during the second auxiliary touch detection period (653) to the third predetermined time (250 ms). If only the section includes a portion of the first debounce section 635 of the auxiliary touch signal b1, the main touch signal a1 corresponding to the single touch signal can be processed effectively.

FIG. 16H shows a case in which continuous touches occur on the main touch sensor after one touch occurs on the auxiliary touch sensor, and the wearable electronic device (e.g., the wearable electronic device 501 of FIG. 10) is the first touch sensor. Through a computation operation or a second association operation, from a second predetermined time (e.g., 50 ms) before the start of operation of the main touch signal (611) to a third predetermined time (250 ms) from the time of release of the main touch signal (613). In the second auxiliary touch detection period up to, the first debounce period 635a of the auxiliary touch signal b1 that is longer than the second critical period (e.g., 80 ms) and extended by the first predetermined time (300 ms) is the second auxiliary touch signal (b1). Since it is partially included in the auxiliary touch detection section 653, the first main touch signal (a1) corresponding to the single touch signal can be treated as invalid.

When processing the first main touch signal (a1) as invalid, the wearable electronic device generates an auxiliary touch signal from the time of cancellation (613a) of the invalid first main touch signal until a first certain period of time (e.g., 300 ms). A random extension section 637a is set by extending the first debounce section, and the random extension section 637a includes a portion of the second main touch signal, so that the second main touch signal corresponding to the single touch signal (a1) can be treated as invalid.

When processing the second main touch signal (a1) as invalid, the wearable electronic device generates an auxiliary touch signal from the point in time (613b) of canceling the operation of the invalidated second main touch signal until a first certain period of time (e.g., 300 ms). A random extension section 637b is set by extending the first debounce section, and since the third main touch signal is not included in the random extension section 637b, the third main touch corresponding to the single touch signal The signal (a1) can be processed effectively.

As shown in FIGS. 16A to 16H, when the main touch signal is generated, the auxiliary touch detection section, which is a virtual area waiting for the auxiliary touch signal, is set as wide as possible, and when the auxiliary touch signal is generated, the length of the auxiliary touch signal is forcibly extended. Or, when a case occurs in which the main touch signal is processed as invalid, it is determined that the user is performing a rewriting operation for wearing a wearable electronic device (e.g., earbuds), and a certain period of time is elapsed from the time of release of the main touch signal. By arbitrarily setting the auxiliary touch signal to be generated, the main touch signals that follow may be invalidated by the user continuously rewriting the wearable electronic device (e.g., earbuds) worn, resulting in additional malfunctions.

16A to 16H, when a user touches the main touch sensor first and then touches the auxiliary touch sensor while holding a wearable electronic device (e.g., an earbud), the user touches the auxiliary touch sensor first and then touches the auxiliary touch sensor. When touching the main touch sensor, after a refresh while wearing a wearable electronic device (e.g. earbuds), when touching the main touch sensor, or during a refresh while wearing a wearable electronic device (e.g. earbuds) Malfunction of the main touch signal that occurs when the electronic device is pushed while touching the touch sensor can be resolved.

FIGS. 17A to 17B are diagrams 1700a to 1700e for explaining an operation of additionally confirming an invalidated single touch signal in a wearable electronic device according to an embodiment.

FIG. 17A shows cases in which an auxiliary touch signal is generated together with a main touch signal due to various touch methods. It can be seen that in these cases, the generation forms of the auxiliary touch signal and the main touch signal are similar. there is. In the case shown in FIG. 17A, when the main touch signal corresponding to the single touch signal is processed as invalid, the wearable electronic device (e.g., the wearable electronic device 501 in FIG. 10) processes the invalid signal through the third operation operation. You can additionally check the validity of the main touch signal corresponding to the single touch signal.

Referring to FIG. 17B, the wearable electronic device (e.g., the wearable electronic device 501 of FIG. 10) invalidates the main touch signal corresponding to the single touch signal through the first and second calculation operations. In this case, a third calculation operation can be performed. Through the third operation, the wearable electronic device generates an absolute value time difference (CH0) (691) between the operation start point of the main touch signal (611) and the operation start point of the auxiliary touch signal (631), and the main touch signal. The sum (60ms) of the absolute time difference (CH1) (693) between the signal's operation release point (613) and the auxiliary touch signal's operation release point (633) is less than or equal to the threshold time (80ms) (CH0 + CH1 Time <80ms ), the main touch signal corresponding to the single touch signal can be effectively processed.

FIGS. 18A to 18E are diagrams 1800a to 1800e for explaining an operation of invalidating a long touch signal in a wearable electronic device according to an embodiment.

In FIG. 18A, under the condition of validly processing the main touch signal corresponding to the long touch signal in the second to third operation operations, an exception operation (e.g., exception operation 1 to exception operation 15) is performed according to the condition. indicates that the main touch signal is processed as invalid, operations (e.g., actions 1 to 13) indicate that the main touch signal is processed as valid, and mistouch (e.g., otouch 2) indicates that the wrong area is touched in the wearable electronic device. This indicates a case where the main touch signal is not activated because the main touch signal is not sufficiently generated, and rewrite recognition (e.g., rewrite recognition 1 to rewrite recognition 6) is performed when the user attempts to touch the main touch sensor, but the auxiliary touch sensor is not activated. This indicates that the main touch signal is invalidated as the touch sensors are touched together. An exceptional case of non-recognition of the main touch signal that is not resolved through the first to second calculation operations as shown in FIG. 18A may be processed through the third calculation operation as shown in FIGS. 18B to 18E.
