For example, as shown in 601 of FIG. 6 , a part of the user's body (eg, finger e) is placed on at least one electrode 310 disposed on the outer surface of the housing 300 of the wearable device 200 . When an electrical signal is generated in the at least one electrode 310 as it is touched, the wearable device 200 (eg, the sensor device 410) responds to the generated electrical signal as shown in 602 of FIG. 6 . Based on the sampled plurality of values (eg, first values) may be obtained. As the generated electrical signal is converted by the multiplexer 440 and the A/D converter 450 of the sensor device 410 , the wearable device 200 (eg, the sensor device 410 ) generates the plurality of values of can be obtained, and since the operation of obtaining the plurality of values can be performed as described above, a redundant description will be omitted.

According to various embodiments, the wearable device 200 may acquire a plurality of second values using the acceleration sensor 431 in operation 503 . For example, as shown in 601 of FIG. 6 , a sensor disposed inside the housing 300 as a part of the user's body (eg, finger e) comes into contact with the housing 300 of the wearable device 200 . When an electrical signal is generated by the acceleration sensor 431 of the device 410 , the wearable device 200 (eg, the first processor 411 of the sensor device 410 ) is configured as shown in 602 of FIG. 6 . A plurality of sampled values (eg, second values) may be obtained based on the generated electrical signal. When a part of the user's body comes into contact with the wearable device 200, the wearable device 200 may vibrate, and additional vibrations provided for each axis included in the acceleration sensor 431 are further vibrated to change the capacitance value. A signal may be generated at the acceleration sensor 431 . As the generated electrical signal is converted by the multiplexer 440 and the A/D converter 450 of the sensor device 410, the wearable device 200 (eg, the sensor device 410) generates the plurality of values of can be obtained, and since the operation of obtaining the plurality of values can be performed as described above, a redundant description will be omitted.

According to various embodiments, the wearable device 200 performs at least one of a plurality of first values obtained using the at least one electrode 310 or a plurality of second values obtained using the acceleration sensor 431 in operation 505 . Based on one, an interrupt signal indicating a specific touch type may be generated. For example, the touch type includes a long touch (eg, a touch maintained for a specified time or longer) and n touches, wherein the n touches are a single touch when n is 1, and n is A double touch in the case of 2 may be included, but is not limited thereto, and n touches may include more types of touches according to the value of n. When a specific touch type event occurs, the wearable device 200 (eg, the first processor 411 of the sensor device 410 ) returns to the identified touch type (or the identified event) stored in the memory 417 . A corresponding interrupt signal may be identified, and the identified interrupt signal may be generated and transmitted to the second processor 420 . The interrupt signal may include information indicating the identified touch type (or an event of a specific touch type that has occurred). The wearable device 200 (eg, the sensor device 410 ) uses a plurality of first values indicating the type of dielectric and a contact method of the dielectric, or a plurality of second values indicating acceleration together with the first values. Accordingly, the type of the touch applied to the wearable device 200 by the current user may be identified (or the occurrence of an event of the specific touch type) may be identified. Hereinafter, an example of an operation in which the wearable device 200 (eg, the sensor device 410 ) uses a plurality of values (eg, first values and second values) to identify a touch type will be described.

In an embodiment, the wearable device 200 (eg, the sensor device 410 ) may identify a long touch (or identify occurrence of a long touch event) by using the plurality of obtained first values. For example, the wearable device 200 (eg, the sensor device 410 ) maintains a contact time (hereinafter, touch holding time), and when the touch holding time is equal to or greater than a threshold time, a long touch (or occurrence of a long touch event) may be identified. As an example, the wearable device 200 (eg, the sensor device 410 ) sequentially calculates the difference (or variance) between the plurality of first values (eg, the difference between the n-th sampled value and the n+1-th value). count, and identify the number of times the sequentially calculated difference is greater than or equal to a first threshold value (or within a first specified range). As will be described later, the first threshold value or the first designated range is a pattern of a signal generated by the at least one electrode 310 when a part of the user's body is in contact with the at least one electrode 310 (eg, in time may be set based on the change in the value of the signal). The number of times the calculated difference is equal to or greater than the first threshold value (or within a specified range) may indicate a touch holding time (or may correspond to a touch holding time). For example, the touch holding time may be proportional to the number of times. As a specific example, the number of times equal to or greater than the first threshold value (or within a specified range) may be a long-touch count, which will be described later with reference to FIGS. 10 to 11 . In an embodiment, in the wearable device 200 (eg, the sensor device 410 ), a difference between the plurality of first values obtained using at least one electrode 310 is equal to or greater than a first threshold value (or a specified range). It can be identified that the number of times within) is greater than the threshold number of times. The wearable device 200 (eg, the sensor device 410 ) may identify that the touch holding time is greater than a threshold time based on the identification, but is not limited thereto. In this case, the wearable device 200 (eg, the sensor device 410 ) may identify that a long touch event has occurred. In another embodiment, the wearable device 200 (eg, the sensor device 410 ) identifies that the number of times the difference between the plurality of first values is less than the first threshold value (or is outside the first specified range) is less than the threshold number (or, identifying the number of times greater than or equal to another preset number). The wearable device 200 (eg, the sensor device 410 ) may identify that the touch holding time is less than a threshold time based on the identification, but is not limited thereto. In this case, the wearable device 200 (eg, the sensor device 410 ) identifies that the long touch event has not occurred and performs an operation for identifying the long-touch event (eg, a plurality of first values and a first threshold). value comparison) can be aborted. As a specific example, the number of times equal to or greater than the first threshold value (or within a specified range) may be a no long-touch count, which will be described later with reference to FIGS. 12 to 13 .

Hereinafter, an example of an operation in which the wearable device 200 identifies a touch type (eg, n touches) using a plurality of first values and a plurality of second values will be described.

In an embodiment, the wearable device 200 (eg, the sensor device 410 ) identifies n touches (or generation of n touch events) by using the plurality of obtained first values and the plurality of second values. can be identified). For example, when the difference (or variance) between the plurality of first values is greater than or equal to a threshold value, the wearable device 200 (eg, the sensor device 410 ) may be configured to perform the It is possible to identify the number of times (n times) that the user's body part has been touched on the at least one electrode 310, and identify n touches (or identify the occurrence of n touch events) according to the identified number of times. . For example, the wearable device 200 (eg, the sensor device 410 ) may further refer to the obtained plurality of second values when a difference (or variance) between the plurality of second values is greater than or equal to a first threshold value. to calculate a difference (or variance) between the plurality of second values, and identify the number of times the calculated difference is equal to or greater than a second threshold value (or within a second specified range). The second threshold value (or the second specified range) may be set to a value different from the above-described first threshold value (or the first specified range), and when a part of the user's body of the wearable device 200 comes into contact It may be set based on a pattern of a signal generated by the acceleration sensor 431 (eg, a change in signal value over time). As a specific example, the number of times that is equal to or greater than the identified second threshold value (or within a second specified range) may be a touch count, which will be described later with reference to FIGS. 12 to 13 . The wearable device 200 (eg, the sensor device 410 ) stores information about the threshold number (or a specific range) corresponding to each n touches in a memory 417 in advance, and based on the stored information, the When the number of times equal to or greater than the identified second threshold value (or within the second specified range) is equal to or greater than the threshold number (or included in a specific range), n touches corresponding to the threshold number (or specific range) may be identified. may be (or, it may be identified as having been touched n times). As an example, when the threshold number of times is set to 3 for a single touch in which n is 1 and the threshold number is set to 6 for a double touch in which n is 2, the sensor device 410 performs the above-identified second threshold ( Alternatively, when the number of times (within the second specified range) is 5, a single touch may be identified (or occurrence of a single touch event may be identified).

For example, the second processor 420 transmits information notifying that a specific type of touch corresponding to the interrupt signal is generated to the main processor (eg, CPU or AP) (not shown) based on the reception of the interrupt signal. can A main processor (eg, CPU or AP) (not shown) may identify that the specific type of touch is generated and perform an operation corresponding to the specific type of touch. For example, when a long-touch of the wearable device (eg, a main processor (eg, CPU or AP) (not shown)) occurs, an incoming call may be rejected. Also, for example, the wearable device (eg, a main processor (eg, CPU or AP) (not shown)) may pause a currently playing song or play a song when a single touch occurs. Also, for example, the wearable device (eg, a main processor (eg, CPU or AP) (not shown)) may play a next song or answer and end a call when a double-touch occurs. Also, for example, a wearable device (eg, a main processor (eg, CPU or AP) (not shown)) may play a previous song when a touch occurs three times.

For example, when the user touches the at least one electrode 310 disposed on the outer surface of the housing 300 of the wearable device 200 as described above in FIG. 6 , the at least one electrode 310 and the sensor An electrical signal (eg, current or voltage) may be generated based on the generation and/or change of the capacitance value in each of 415 (eg, the acceleration sensor 431 ).

A first electrical signal (eg, a signal indicating a change in constant voltage) is obtained, and an electrical second signal (eg, a change in acceleration) transmitted from the output terminal of the acceleration sensor 431 to the second input terminal 443 is obtained. signal) can be obtained. The output terminal of the acceleration sensor 431 connected to the second input terminal 443 may be a single output configured to output an electrical signal for acceleration associated with a specific axis. On the other hand, without being limited to the illustrated and/or described, the other output terminals of the acceleration sensor 431 (eg, an electrical signal for acceleration associated with another axis) to the remaining input terminals 445 (not illustrated) of the multiplexer 440 . output terminals implemented to output ?), and output terminals of at least one other sensor 415 (eg, an angular velocity sensor (or gyro sensor) 433) may be connected to each other. Hereinafter, examples of operations of the multiplexer 440 and the A/D converter 450 included in the sensor device 410 will be further described.

According to various embodiments, the multiplexer 440 may output one signal among a plurality of signals at a specified period (T). For example, the first processor 411 may control the multiplexer 440 to output one signal among a plurality of signals (eg, the first signal and the second signal) at a specified period T. . For example, the first processor 411 may transmit a control signal for controlling the output of a signal of a specific input terminal to the multiplexer 440 at a specified period (T). The control signal may include information about a bit value indicating a specific input terminal. Although not shown, the first processor 411 is connected to at least one input terminal for receiving the control signal of the multiplexer 440 through at least one control signal line, and receives a control signal through the control signal line. can transmit The multiplexer 440 may select a specific input terminal corresponding to the control signal from among a plurality of input terminals at a specified period based on receiving the control signal, and output a signal input to the selected specific input terminal. In one embodiment, the first processor 411 selects an input terminal in the order (eg, in the order of a number set in the input terminal) from among the plurality of input terminals 441 , 443 , 445 by the multiplexer 440 at a specified period can be controlled to output a signal. For example, the first processor 411 transmits a control signal indicating a specific input terminal among the plurality of input terminals 441 , 443 , and 445 to the multiplexer 440 at one point in time, After a time, a control signal indicating the next other input terminal may be transmitted to the multiplexer 440 . In another embodiment, the first processor 411 has the multiplexer 440 connected to at least one electrode 310 among the plurality of input terminals 441 , 443 and 445 at a specified period (eg, the first The input terminal 441) and an input terminal connected to the acceleration sensor 431 (eg, the second input terminal 443) may be selected and controlled to output a signal. A corresponding embodiment will be further described later with reference to FIG. 9 . On the other hand, without being limited to the description, the operation of controlling the multiplexer 440 of the first processor 411 is a configuration other than the first processor 411 (eg, another processor in the sensor device 410, or a multiplexer Since it may be performed in a processor separately implemented to control only the lexer 440), and other configurations may also perform the control operation as described above, a redundant description will be omitted.

According to various embodiments, the operation of controlling the multiplexer 440 of the first processor 411 may be performed under a specified condition. For example, when the wear of the user is sensed, the first processor 411 may perform an operation to control the multiplexer 440 .

According to various embodiments, the A/D converter 450 may convert a signal periodically received from the multiplexer 440 into a digital value (or digital data) and transmit it to the first processor 411 . For example, the A/D converter 450 converts a first signal (eg, a signal representing a change in a constant voltage value) periodically received from the multiplexer 440 to convert the first signal that is digital data representing a change in the constant voltage value. Outputs 1 values 820a and 820b (electrode values), and converts a second signal (eg, a signal representing a change in acceleration) to second values 810a and 810b that are digital data representing a change in acceleration (acceleration sensor) value) can be output. The first processor 411 may acquire the received digital values (eg, electrode values and acceleration sensor values) as shown in FIG. 8B . The X-axis of the graph shown in FIG. 8B is a sampling number (n) indicating the order in which digital values are acquired, and the Y-axis indicates the magnitude of the value, and the unit may be a bit, but is not limited thereto. As a result, the specified period (T) described above may be the sampling rate for the signal. At this time, the first processor 411 transmits the control signal for controlling the output of the signal of the specific input terminal, the digital value received from the A/D converter 450 is at least one electrode 310 or It may be identified whether the value is related to the acceleration sensor 431 . For example, when the first processor 411 transmits a control signal corresponding to the first input terminal 441 to which at least one electrode 310 is connected at a first time point, the first processor 411 received within a specified time from the first time point. A value of 1 may be identified as a value corresponding to the first input terminal 441 . In this case, the first processor 411 may identify the first value as a value (eg, a touch value) indicating the type of the dielectric and/or the contact method of the dielectric. As the first processor 411 performs the above-described identification operation on other values (eg, acceleration values), the plurality of first values 810a and 810b and the plurality of second values are identified as shown in FIG. 8B . (820a, 820b) may be obtained.

According to various embodiments, the sensor device 410 may generate an interrupt signal indicating a specific type of touch event based on at least one of a plurality of first values or a plurality of second values in operation 705 . For example, the first processor 411 may identify a touch holding time based on a plurality of first values, and identify a long-touch based on the identified touch holding time. Also, for example, the first processor 411 may identify the number of times the user's body has been touched based on the plurality of first values and the plurality of second values, and may identify n touches based on the identified number of times. have. Since operation 705 of the sensor device 410 may be performed like operation 505 of the above-described wearable device 200 , a redundant description will be omitted. Based on the identification of the type of touch, the first processor 411 may generate a specific interrupt signal corresponding to the type of touch and transmit it to the second processor 420 .

Hereinafter, an example of the operation of the sensor device 410 according to various embodiments will be described.

According to various embodiments, when a specified condition is satisfied, the sensor device 410 selects at least one It is possible to control to output a signal received through the electrode 310 and a signal received from the acceleration sensor 431 . Accordingly, when the type of touch is required to be recognized, only values necessary for recognizing the type of touch can be acquired with relatively low power and at a higher sampling rate.

9 is a flowchart 900 for explaining an example of an operation of the sensor device 410 according to various embodiments. The operations illustrated in FIG. 9 are not limited to the illustrated order and may be performed in various orders. In addition, according to various embodiments, more operations than those illustrated in FIG. 9 or at least one fewer operations may be performed.

According to various embodiments, the sensor device 410 may control the multiplexer 440 to output a signal received to each of the plurality of input terminals in a first cycle in operation 901 . For example, the sensor device 410 may include a plurality of input terminals 441 , 443 , and 445 of the multiplexer 440 in a first period T1 from a point in time when wearing of the wearable device 200 is sensed, respectively. It is possible to control to output the signals received in order. Accordingly, the wearable device 200 may measure various types of physical signals (eg, acceleration, slope, and temperature).

According to various embodiments, the sensor device 410 identifies the satisfaction of the specified condition in operation 903 , and in operation 905 , a first input terminal 443 connected to at least one electrode of the plurality of input terminals with a shorter period than the first period. ) and a second input terminal 445 connected to a specific sensor (eg, the acceleration sensor 431), respectively, may control the multiplexer to output a received signal. For example, the satisfaction of the specified condition may include that at least one of values for identifying the type of touch (eg, a long touch or n touches) is greater than or equal to a threshold value. For example, the sensor device 410 (eg, the first processor 411 ) may have at least one of a value obtained using the at least one electrode 310 or a value obtained using the acceleration sensor 431 . If it is greater than or equal to the set threshold, it may be determined that the specified condition is satisfied. In this case, the first processor 411 uses a second cycle T2 that is shorter than the first cycle T1 so that the multiplexer 440 identifies the type of touch (eg, a long touch or n touches). You can control to output only the values for For example, the first processor 411 includes an input terminal connected to at least one electrode 310 (eg, a first input terminal 441 ) and an input terminal connected to the acceleration sensor 431 (eg, a second input terminal). 443)) is transmitted to the multiplexer 440 in a second period T2, and the multiplexer 440 receives the received signal to the first input terminal 441 in a second period T2. A signal and a signal received through the second input terminal 443 may be output. Accordingly, the sampling rate is higher at a sampling rate corresponding to the second period T2, and the sensor device 410 sets the type of touch (eg, long touch, or n) at a higher sampling rate when identification of the type of touch is required. Only values (eg, first values and second values) for identifying a touch) may be obtained. Accordingly, since the first processor 411 may not process (or may not acquire) other values (eg, a gradient value), an operation burden may be reduced.

The operation described in FIGS. 10 and 11 below may be defined as a long-touch identification operation, and the operation described in FIGS. 12 and 13 may be defined as an n-touch identification operation. Each operation may be performed in parallel in the wearable device 200 . As described above, when a plurality of touch events are generated according to each operation, it may be identified that a specific touch event has occurred according to the priority of the generated touch events. In an embodiment, the long-touch event has the highest priority, and accordingly, when the long-touch event and other n touch events occur at the same time, the long-touch event may be identified as being generated.

Hereinafter, examples of operations of the wearable device 200 according to various embodiments will be described.

According to various embodiments, the wearable device 200 identifies a long touch (or identifies occurrence of a long touch event) based on a difference value between a plurality of first values obtained using the at least one electrode 310 . )can do. The wearable device 200 compares a difference value between the plurality of first values with a preset threshold value, and sets a parameter (eg, long- Touch Count) can be set (eg, incremented) and a long touch can be identified based on the setting of the value.

10 is a flowchart 1000 for explaining an example of an operation of the wearable device 200 according to various embodiments of the present disclosure. The operations illustrated in FIG. 10 are not limited to the illustrated order and may be performed in various orders. In addition, according to various embodiments, more operations than the operations illustrated in FIG. 9 or at least one fewer operations may be performed. Hereinafter, FIG. 10 will be described with reference to FIGS. 11A and 10B.

11A illustrates an example of a plurality of first values obtained while the sensor device 410 (eg, the first processor 411 ) performs an operation for identifying a long-touch according to various embodiments of the present disclosure; It is a drawing. 11B illustrates another example of a plurality of first values obtained while the sensor device 410 (eg, the first processor 411 ) performs an operation for identifying a long-touch according to various embodiments of the present disclosure; It is a drawing. The first values (eg, 1101 , 1102 , 1103 ) of FIGS. 11A and 11B may be digital data representing a change in the constant voltage value as described above with reference to FIG. 8 , and overlapping descriptions will be omitted.

According to various embodiments, the wearable device 200 obtains a plurality of values by using the at least one electrode 310 in operation 1001 , calculates a difference between the plurality of values in operation 1003 , and determines the difference value in operation 1005 . It can be determined whether it is greater than a threshold value. For example, as a part of the user's body (eg, finger e) is in contact with the at least one electrode 310 as described above, an electrical signal generated from the at least one electrode 310 is transmitted to the sensor device 410 . ) (eg, the multiplexer 440). The sensor device 410 (eg, the first processor 411) converts the received electrical signal into digital data as shown in FIG. 11A (eg, a plurality of first values 1101, 1102, 1103). )) can be obtained sequentially. As described above in FIG. 8 , each of the first values 1101 , 1102 , and 1103 may be digital data representing a change in a constant voltage value. Since the operation of the sensor device 410 (eg, the first processor 411 ) acquiring the converted value may be performed as described above, a redundant description thereof will be omitted. In this case, the sensor device 410 (eg, the first processor 411 ) may calculate a difference between a value in a specific order and a value in an order before the specific order. For example, the sensor device 410 (eg, the first processor 411 ) may calculate the difference d1 between the nth value 1101 and the n+1th value 1102 as shown in FIG. 11A . have. In one embodiment, the value of the specific order may be a currently obtained value (eg, a value obtained in the current order), and may be a value obtained immediately before the currently obtained value (eg, a value obtained in the immediately previous order). However, the present invention is not limited thereto, and the sensor device 410 (eg, the first processor 411 ) may calculate a difference by selecting two values in the previous order and the next order from among previously acquired values. The sensor device 410 (eg, the first processor 411 ) may perform an operation of comparing the difference value d1 obtained based on the calculation of the difference with a preset threshold value (or a specified range). have. Although the sensor device 410 (eg, the first processor 411) will be described later, an operation of increasing the value of a first parameter (eg, long-touch count) for long touch identification based on the comparison operation or long touch identification An operation for increasing the value of the second parameter (eg, no long-touch count) for completion of the operation may be performed.

According to various embodiments, the threshold value (or a specified range) compared with the difference value between the plurality of first values is a body part (eg, a finger (eg, a finger) of the user in contact with the at least one electrode 310 It may be a predetermined value (or a range of values) according to a pattern of values of the electrical signal generated by e)). For example, a pattern of a signal value (eg, a change in value over time) may be different according to a type of a dielectric contacting the at least one electrode 310 . For example, when the user's body is in contact with the at least one electrode 310, a signal of a sinusoidal waveform may be generated. Accordingly, a specific signal (eg, a sine wave signal) generated when a part of the user's body (eg, finger e) is in contact with at least one electrode 310 is sampled at a specified period T, and sampling The threshold value may be determined in advance based on a difference between the calculated values. For example, when an average value of a difference between sampled values obtained from a signal when a part of the user's body is in contact is a first value, the threshold value is greater or smaller than the first value or the first value by a specific value It can be set to a value. As another example, when the user's body part (eg, finger e) is in contact with at least one electrode 310, the range of the difference between the sampled values obtained from the signal is greater than or equal to the second value and less than or equal to the third value. can In this case, the specified range may be set to be greater than or equal to the second value and less than or equal to the third value, or greater than or less than a value greater or less than the second value by a specific value and less than or equal to a value greater or less than the third value by a specific value.

According to various embodiments, when the difference value is greater than the threshold value, the wearable device 200 may increase the value of the first parameter for long touch identification in operation 1007 and resume operation 1001 . For example, the first parameter is a parameter previously implemented for long touch identification and may be defined as a long-touch count. The sensor device 410 (eg, the first processor 411 ) may increase the value of the first parameter (eg, long-touch count) when the calculated difference value d1 is greater than the threshold value. For example, when the value of the previous first parameter (eg, long-touch count) is a, the sensor device 410 (eg, the first processor 411 ) transmits the first parameter (eg, long-touch count). ) can be increased by 1 to a+1. Further, the present invention is not limited thereto, and may be further increased by a value other than 1 . When the sensor device 410 (eg, the first processor 411 ) increases the value of the first parameter (eg, long-touch count), the sensor device 410 (eg, the long-touch count) continues and sequentially sets the following values (eg, the n+1th value 1102 ). ) and the n+2th value 1103 ) and comparing the calculated difference value d2 with a threshold value may be performed. As a result, the above-described operation is repeated and the value of the first parameter (eg, long-touch count) or the value of the second parameter (eg, no long-touch count) may be increased.

According to various embodiments, when the difference value is not greater than (or less than) the threshold value, the wearable device 200 may increase the value of the second parameter for long touch identification completion in operation 1009 . For example, the second parameter is a parameter pre-implemented for completing a long-touch identification operation (eg, at least a part of operations 1001 to 1013 of FIG. 10 ) (eg, completing an operation of increasing values of parameters). As such, it may be defined as a no long-touch count. The sensor device 410 (eg, the first processor 411) determines the value of the second parameter (eg, no long touch count) when the calculated difference value d1 is not greater than (or less than) the threshold value. can increase For example, if the value of the previous second parameter (eg, no long touch count) is b, the sensor device 410 (eg, the first processor 411) transmits the second parameter (eg, no long touch count). ) can be increased by 1 to b+1. Further, the present invention is not limited thereto, and it may be further increased by a value other than 1 .

According to various embodiments, the wearable device 200 may determine whether the value of the second parameter is greater than the first threshold in operation 1011 . The first threshold value may be a preset value to be compared with a second parameter (eg, no-long touch count) to complete the long-touch identification operation of the wearable device 200 (eg, the sensor device 410). have. Completion of the long-touch identification operation may mean that the value of the first parameter is no longer increased by determining whether to increase the value of the first parameter (eg, long-touch count) and completing the operation to increase it. . Accordingly, when the value of the second parameter (eg, no-long touch count) is greater than the first threshold value, the wearable device 200 (eg, the sensor device 410 ) performs the first parameter (eg, long-touch). count), operation 1013 for identifying a long-touch may be performed, and operation 1013 will be described later. Also for example, when the value of the second parameter (eg, no-long touch count) is not greater than (or smaller than) the first threshold value, the sensor device 410 (eg, the first processor 411 ) case), restart operation 1001 and sequentially calculate the difference between the following values (eg, the n+1th value 1102 and the n+2th value 1103) and add the calculated difference value and the threshold value. A comparison operation can be performed. As a result, the above-described operation is repeated and the value of the first parameter (eg, long-touch count) or the value of the second parameter (eg, no long-touch count) may be increased.

According to various embodiments, when the value of the second parameter is greater than the first threshold value, the wearable device 200 determines whether the value of the first parameter is greater than the second threshold value in operation 1013, and the value of the first parameter If it is greater than the second threshold, a long touch may be recognized in operation 1015 . The sensor device 410 (eg, the first processor 411) completes the operation for long touch identification when the value of the second parameter (eg, no-long touch count) is greater than a preset first threshold value. can Thereafter, the sensor device 410 (eg, the first processor 411 ) continuously compares the value of the first parameter (eg, long touch count) that has been accumulated (or increased) up to now and a preset second threshold value. can The second threshold value is a preset reference value to be compared with a value of a first parameter (eg, long touch count) for long-touch identification, and may be set to a value different from the above-described first threshold value. For example, the second threshold value may be set to a value greater than the first threshold value, but is not limited thereto and may be set to a smaller value. When the value of the first parameter (eg, long touch count) is greater than the second threshold value, the sensor device 410 (eg, the first processor 411 ) identifies a long touch as shown in FIG. 11A ( Alternatively, the generation of the long touch event may be identified) and a specific interrupt signal indicating the long touch may be generated and transmitted to the second processor 420 based on the identification. Alternatively, when the value of the first parameter (eg, long touch count) is smaller than the second threshold value, the sensor device 410 (eg, the first processor 411 ) identifies a long touch as shown in FIG. 11B . Failing to do so, the operation may be terminated (or it may be identified that the long-touch event has not occurred). For example, referring to FIG. 11B , when the holding time of the touch received on the at least one electrode 310 is not sufficient, the value of the second parameter (eg, no-long touch count) is increased to increase the first threshold value. However, the value of the first parameter (eg, long touch count) may not be sufficiently increased to be greater than the second threshold value. As a result, the value of the second parameter (eg, no-long touch count) becomes greater than the first threshold value to complete the long-touch identification operation, but the sensor device 410 (eg, the first processor 411) performs the first It may be identified that the parameter (eg, long-touch count) is less than the second threshold value. Accordingly, unlike shown in FIG. 11A , an interrupt signal corresponding to a long-touch may not be generated. Accordingly, the sensor device 410 (eg, the first processor 411) initializes the value of the first parameter (eg, long-touch count) and the value of the second parameter (eg, no-long touch count), and You can end the action.

Meanwhile, according to various embodiments, it has been described that the wearable device 200 (eg, the sensor device 410 ) performs operations 1001 to 1013 while a plurality of first values are acquired in real time, but the description is not limited thereto. It may also be set to perform at least some of the operations (eg, operations 1001 to 1013) from a specific point in time. For example, the sensor device 410 (eg, the first processor 411 ) uses the at least one electrode 310 to recognize that the value currently acquired exceeds the threshold value, 1003 operation for calculating the difference may be performed.

Meanwhile, according to various embodiments, it has been described that the wearable device 200 (eg, the sensor device 410) increases the value of the parameter (eg, long-touch count, or no long-touch count). The algorithm may be implemented by decreasing the value from the value of the preset parameter without being limited.

Hereinafter, examples of operations of the wearable device 200 according to various embodiments will be described.

According to various embodiments, the wearable device 200 uses a difference value between a plurality of first values obtained using at least one electrode 310 and a sensor 415 (eg, an acceleration sensor 431 ). Based on the obtained difference value between the plurality of second values, n touches may be identified (or occurrence of n touch events may be identified). For example, the wearable device 200 is configured to identify n touches (or to identify occurrence of n touch events) according to a comparison between a difference value between the plurality of second values and a preset threshold value. You can set (eg, increase) the value of a parameter (eg, touch count) and identify n touches based on the set value.

12 is a flowchart 1200 illustrating an example of an operation of the wearable device 200 according to various embodiments of the present disclosure. The operations illustrated in FIG. 12 are not limited to the illustrated order and may be performed in various orders. In addition, according to various embodiments, more operations than those illustrated in FIG. 12 or at least one fewer operations may be performed. Hereinafter, FIG. 12 will be described with reference to FIGS. 13A and 13B.

13A is a diagram illustrating a plurality of first values and a plurality of second values obtained while the sensor device 410 (eg, the first processor 411 ) performs an operation of identifying n touches according to various embodiments of the present disclosure; It is a diagram for explaining an example. 13B illustrates a plurality of first values and a plurality of second values obtained while the sensor device 410 (eg, the first processor 411 ) performs an operation of identifying n touches according to various embodiments of the present disclosure; It is a figure for demonstrating another example. As described above in FIG. 8 , the first values (eg, 1310a, 1310b, 1310c, and 1310d) of FIGS. 13A and 13B are digital data representing a change in the constant voltage value, and the second values (eg, 1320a, 1320b, 1320c) are , 1320d) may be digital data representing a change in an acceleration value, and a redundant description will be omitted.

According to various embodiments, the wearable device 200 obtains a plurality of first values by using the at least one electrode 310 in operation 1201 , calculates a difference between the plurality of first values in operation 1203 , and in operation 1205 . may determine whether the first difference value is greater than a first threshold value. For example, as a part of the user's body (eg, finger e) is in contact with the at least one electrode 310 as described above, the electrical signal generated by the at least one electrode 310 is transmitted to the sensor device ( 410) (eg, the multiplexer 440). The sensor device 410 (eg, the first processor 411) sequentially converts first values 1310a, 1310b, 1310c, and 1310d in which the received electrical signal is converted to digital data, as shown in FIG. 13A . can be obtained As described above in FIG. 8 , the first values (eg, 1310a, 1310b, 1310c, and 1310d) may be digital data representing a change in a constant voltage value, and the sensor device 410 (eg, the first processor 411) Since the operation of obtaining the converted first values 1310a, 1310b, 1310c, and 1310d may be performed as described above, a redundant description will be omitted. The sensor device 410 (eg, the first processor 411 ) calculates a difference between the values of a specific order (eg, 1310a ) and the values of the previous order ( 1310b ) among the acquired values, and calculates the difference. Based on that, the first difference value d may be obtained. Since the operation of obtaining the difference value may be performed as in operations 901 to 903 described above, a redundant description will be omitted. The sensor device 410 (eg, the first processor 411 ) compares the first difference value D1 with a preset first threshold value, and based on the comparison result, the first difference value D1 is set to the first threshold value. If the value is greater than the value, an operation (eg, operations 1207 to 1221 ) for identifying n touches may be performed based on second values obtained by the acceleration sensor 431 , which will be described later. For example, when the first difference value D1 is greater than the first threshold value, the sensor device 410 (eg, the first processor 411 ) may place a part of the user's body (eg, on the at least one electrode 310 ) : It is determined that the finger (e) is in contact, and an operation of continuously identifying n touches may be performed. As an example, referring to FIG. 13A , the sensor device 410 (eg, the first processor 411 ) provides a difference D1 between the nth value 1310a and the n+1th value 1310b (or between 1310b and 1310c). When it is identified that the difference (or the difference between 1310c and 1310d) is greater than the first threshold, operation 1207 may be continuously performed based on the identification. Or, without being limited thereto, the sensor device 410 (eg, the first processor 411 ) may be implemented to perform operation 1207 when the number of times the difference value D1 is greater than the first threshold value is greater than a specified number of times. may be The first threshold value may be the same as the threshold value described above in operation 1005 . When the first difference value D1 is smaller than the first threshold value, the sensor device 410 (eg, the first processor 411) determines that the user's body part (eg, the finger e) is not in contact. and the operation of identifying n touches may be completed.

According to various embodiments, when the first difference value is greater than the first threshold value, the wearable device 200 acquires a plurality of second values related to acceleration by using the acceleration sensor 431 in operation 1207 , and in operation 1209 . may calculate a difference between a plurality of second values, obtain a calculated second difference value, and determine whether the second difference value is greater than a second threshold value in operation 1211 . For example, as a part of the user's body (eg, finger e) comes into contact with the wearable device 200 as described above, an electrical signal generated by the acceleration sensor 431 is transmitted to the sensor device 410 (eg: may be transmitted to the multiplexer 440 . The sensor device 410 (eg, the first processor 411) sequentially converts the received electrical signal to the second values 1320a, 1320b, 1320c, and 1320d as shown in FIG. 13A as digital data. can be obtained As described above in FIG. 8 , the second values (eg, 1320a, 1320b, 1320c, and 1320d) may be digital data representing a change in an acceleration value, and the sensor device 410 (eg, the first processor 411). Since the operation of obtaining the converted second values 1320a, 1320b, 1320c, and 1320d may be performed as described above, a redundant description will be omitted. The sensor device 410 (eg, the first processor 411 ), among the obtained second values 1320a, 1320b, 1320c, and 1320d, is a value of a specific order (eg, the n-th value 1320a) and the previous order. Calculate the difference (or the difference between 1320b and 1320c, 1320c and 1320d) between the values (e.g. the n+1th value 1320b), and based on the calculation of the difference a second difference value ( D2) can be obtained. Since the operation of obtaining the difference value may be performed like the operation of calculating the difference between the plurality of first values, a redundant description will be omitted. The sensor device 410 (eg, the first processor 411 ) compares the obtained second difference value D2 with a preset second threshold value (or a specified range) based on the operation of calculating the difference. action can be performed. Although the sensor device 410 (eg, the first processor 411) will be described later, an operation of increasing the value of the first parameter (eg, touch count) for n-times-touch identification based on the comparison operation or n-times-touch identification An operation for increasing a value of a second parameter (eg, no touch count) for operation completion may be performed.

According to various embodiments, the second threshold value (or a specified range) compared with a second difference value D2 between the plurality of second values 1320a, 1320b, 1320c, 1320d is the wearable device ( 200) according to a pattern (eg, change in value over time) of the value of the electrical signal generated by the acceleration sensor 431 for a specific axis when a part of the user's body (eg, finger (e)) is in contact may be determined. For example, when the user's body is in contact with the wearable device 200, the acceleration sensor 431 samples a specific signal (eg, a sine wave signal) generated for a specific axis at a specified period (T), The second threshold value may be predetermined based on a difference between the sampled values. For example, when a first value is an average value of a difference between sampled values obtained from a signal generated with respect to a specific axis by the acceleration sensor 431 when a part of the user's body is in contact, the second threshold value is the second threshold value. It may be set to a value of 1 or a value larger or smaller than the first value by a specific value. As another example, when the user's body part (eg, finger e) is in contact, the range of the difference between the sampled values obtained from the signal generated by the acceleration sensor 431 is greater than or equal to the second value and less than or equal to the third value. can In this case, the designated range may be set to be greater than or equal to the second value and less than or equal to the third value, or greater than or less than a value greater or less than the second value by a specific value and less than or equal to a value greater or less than the third value by a specific value.

According to various embodiments, when the second difference value is greater than the second threshold value, the wearable device 200 increases the value of the first parameter for n-times touch identification in operation 1213 and resumes operation 1207. have. For example, the first parameter is a parameter previously implemented to identify the number of times that the wearable device 200 is touched (or touched) by the user, and may be defined as a touch count. The value of the first parameter and the number of times touched (or touched) by the user may be proportional to each other. The sensor device 410 (eg, the first processor 411 ) may increase the value of the first parameter (eg, touch count) when the calculated second difference value D2 is greater than the second threshold value. . For example, when the value of the previous first parameter (eg, touch count) is a, the sensor device 410 (eg, the first processor 411) receives the value of the first parameter (eg, touch count). It can be increased by 1 with a+1. Further, the present invention is not limited thereto, and it may be further increased by a value other than 1 . When the sensor device 410 (eg, the first processor 411) increases the value of the first parameter (eg, the touch count), the sensor device 410 (eg, the first processor 411) continues to sequentially perform the following values (eg, the n+1th value 1320b) and An operation of calculating a difference between the n+2 th value 1320c) and comparing the calculated difference value with a threshold value may be performed. Accordingly, as a result, the above-described operation may be repeated and the value of the first parameter (eg, touch count) or the value of the second parameter (eg, no touch count) may be increased. For example, as the acceleration value is greatly changed twice in the case of double touch as shown in FIG. 13B , the value of the first parameter may be further increased compared to the case of single touch shown in FIG. 13A .

According to various embodiments, when the second difference value is not greater than (or less than) the second threshold value, the wearable device 200 increases the value of the second parameter for n-times touch identification completion in operation 1215 . can do it For example, the second parameter is a parameter pre-implemented to complete the n touch identification operation (eg, at least some of operations 1201 to 1221 of FIG. 12 ), and may be defined as a no touch count. . The sensor device 410 (eg, the first processor 411) determines the value of the second parameter (eg, no-touch count) when the calculated difference value D2 is not greater than (or less than) the threshold value. can increase For example, if the value of the previous second parameter (eg, no-touch count) is b, the sensor device 410 (eg, the first processor 411) sets the value of the second parameter to b+1 and 1 can be increased by Further, the present invention is not limited thereto, and may be further increased by a value other than 1 .

According to various embodiments, the wearable device 200 may determine whether the value of the second parameter is greater than a third threshold in operation 1217 . The third threshold value may be a value preset to be compared with a second parameter (eg, no-touch count) to complete the n-times touch identification operation of the wearable device 200 (eg, the sensor device 410 ). Completion of the n-times touch identification operation may mean that the value of the first parameter is no longer increased by determining whether to increase the value of the first parameter (eg, touch count) and completing the operation to increase the value. Accordingly, when the value of the second parameter (eg, no-touch count) is greater than the third threshold value, the wearable device 200 (eg, the sensor device 410 ) determines the value of the first parameter (eg, touch count). The 2019 operation for identifying long-n touches may be performed based on , and the 2019 operation will be described later. Also, for example, when the value of the second parameter (eg, no-touch count) is not greater than (or less than) the third threshold value, the wearable device 200 resumes operation 1207 to sequentially set the following values. (For example, an operation of calculating a difference between the n+1th value 1320b and the n+2th value 1320c) and comparing the calculated difference value with a threshold value may be performed. Accordingly, as a result, the above-described operation may be repeated and the value of the first parameter (eg, touch count) or the value of the second parameter (eg, no touch count) may be increased. For example, as shown in FIG. 13B , as the acceleration value is greatly changed twice in the case of a double touch, the value of the first parameter (eg, touch count) is the first parameter in the case of a single touch shown in FIG. 13A . (eg, touch count) may be further increased compared to the value.

According to various embodiments, when the value of the second parameter is greater than the third threshold, the wearable device 200 may determine whether the value of the first parameter is greater than the fourth threshold in operation 1219 . When the value of the second parameter (eg, no-touch count) is greater than the third threshold value, the sensor device 410 (eg, the first processor 411 ) performs parameters (eg, the first parameter and the second The operation of increasing the value of the parameter) can be completed. In addition, the sensor device 410 may compare the value of the first parameter (eg, touch count) with a preset fourth threshold value. The fourth threshold value may be a preset value (or a lower limit value of a preset range) to identify a single touch in which n is 1 among n touches. When the value of the first parameter (eg, touch count) is less than the fourth threshold value, the sensor device 410 (eg, the first processor 411 ) terminates the operation of identifying n touches and the first parameter (eg, touch count) and the value of the second parameter (eg, no touch count) may be initialized.

Meanwhile, without being limited to the order of operations described and/or illustrated, the wearable device 200 performs operation 1219 first, and operation 1217 when the value of the first parameter (eg, touch count) is smaller than the fourth threshold value can also be performed.

According to various embodiments, when the value of the first parameter is greater than the fourth threshold value, the wearable device 200 may identify n touches corresponding to the value of the first parameter in operation 1221 . For example, the wearable device 200 stores information about a threshold value (or a specified range) corresponding to each n touches (where n is 1 or more) in advance, and based on the stored information, the first parameter (eg, : n touches corresponding to the value of the touch count) may be identified. For example, the wearable device 200 stores the above-described fourth threshold value in response to a single touch in which n is 1, and stores a fifth threshold value that is greater than the fourth threshold in response to a double touch in which n is 2 can The present invention is not limited thereto, and as the value of n is larger, the threshold value may be set to a larger value corresponding to n touches. Accordingly, when the value of the first parameter is greater than the fourth threshold value but smaller than the fifth threshold value, the wearable device 200 identifies a single touch (a touch in which n is 1), and as shown in FIG. 13A , Similarly, an interrupt signal corresponding to a single touch can be generated. In addition, when the value of the first parameter is greater than the fifth threshold value, the wearable device 200 identifies a double touch (a touch in which n is 2) and interrupts corresponding to the double touch as shown in FIG. 13B . signal can be generated. The sensor device 410 (eg, the first processor 411 ) may generate a specific interrupt signal corresponding to the identified touch type and transmit it to the second processor 420 . The specific interrupt signal may include information indicating the identified touch type.

According to various embodiments, when the sensor device 410 (eg, the first processor 411 ) is performing the above-described long touch identification operation, the identified n touches based on a result of the long touch identification operation It is possible to generate an interrupt signal corresponding to For example, when the sensor device 410 (eg, the first processor 411 ) completes the long touch identification operation (eg, when the no-long touch count is greater than or equal to a threshold value), the sensor device 410 (eg, the first processor 411 ) responds to the identified n touch A corresponding interrupt signal can be generated. Also for example, when the sensor device 410 (eg, the first processor 411 ) identifies a long touch according to a long touch identification operation (eg, when the long-touch count is greater than or equal to a threshold value), the identified touch Interrupt signals can be generated according to the priority of each type. As described above, the priority of the long touch may be set to have a higher priority than other types of touches. Accordingly, the sensor device 410 (eg, the first processor 411 ) may generate an interrupt signal corresponding to a long touch rather than the identified n touches. As described above, when the sensor device 410 (eg, the first processor 411 ) generates an interrupt signal based on the result of the long-touch identification operation, n identified during the time period during which the long-touch identification operation is performed An operation of generating an interrupt signal corresponding to a single touch may be avoided, and an operation of generating a specific interrupt signal may be performed after (or at a time point) when the operation is completed.

Meanwhile, as described above, according to various embodiments, the wearable device 200 (eg, the sensor device 410) performs operations 1201 to 1205 while the plurality of first values are acquired in real time. It may be set to perform at least some of the operations (eg, operations 1201 to 1205) from a specific point in time without being limited thereto. For example, the sensor device 410 (eg, the first processor 411 ) uses the at least one electrode 310 to recognize that the value currently acquired exceeds the threshold value, An operation 1203 of calculating the difference may be performed.

Meanwhile, according to various embodiments, it has been described that the wearable device 200 (eg, the sensor device 410) increases the value of the parameter (eg, touch count, or no touch count). An algorithm may be implemented by decreasing the value from the value of the set parameter.
