[0001] One embodiment disclosed in this document relates to a wearable device and a method for controlling the same, and relates to a wearable device and a method for controlling the same for generating a control command signal.

[0002] The widespread adoption of wearable electronic devices that can be worn directly on the body is becoming active. Since wearable electronic devices can be mounted on parts of the body, such as fingers, wrists, ankles, necks, waists, or heads, mobility and portability can be improved. Examples of such wearable electronic devices include ring-type wearable devices (e.g., smart rings), watch-type wearable devices (e.g., smart watches), and glasses-type wearable devices (e.g., smart glasses).

[0003] A ring-type wearable device is worn on a user's finger and can collect the user's health information (e.g., heart rate, blood pressure, body temperature), location information, or movement information. The ring-type wearable device may be configured to output a light signal or a vibration signal through an LED indicator or an actuator. The ring-type wearable device is linked with a smartphone to transmit collected information and can transmit alarms obtained from the smartphone to the user.

[0004] A predetermined pattern may be inserted on the outer surface of a ring-type wearable device, and the predetermined pattern may be utilized as a design element. For example, the predetermined pattern may enhance the user experience by expressing the user's individuality and providing aesthetic satisfaction.

[0005] Meanwhile, a ring-type wearable device can provide the function of an input interface that connects to an external device and controls the external device. For example, the ring-type wearable device can receive a user's gesture input, generate a control command signal based on the user's gesture input, and transmit the generated control command signal to an external device.

[0063] Each of the external electronic devices (102, 104) may be of the same or different type as the electronic device (101). According to one embodiment, all or part of the operations performed on the electronic device (101) may be performed on one or more of the external electronic devices (102, 104, or 108). For example, if the electronic device (101) needs to perform a function or service automatically or in response to a request from a user or another device, the electronic device (101) may request one or more external electronic devices to perform at least part of the function or service instead of performing the function or service itself or additionally. Upon receiving the request, one or more external electronic devices may perform at least part of the requested function or service, or additional functions or services related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may provide the result as is or additionally processed as at least part of the response to the request. For example, an external electronic device (102) renders content data executed in an application and transmits it to an electronic device (101), and the electronic device (101) that receives the data can output the content data to a display module. If the electronic device (101) detects user movement through an IMU sensor, etc., the processor of the electronic device (101) can correct the rendering data received from the external electronic device (102) based on the movement information and output it to the display module. Alternatively, the external electronic device (102) can transmit the movement information to request rendering so that the screen data is updated accordingly.

[0151] According to one embodiment, the wearable device (210) can determine in operation 620 whether the vibration signal generated by the gesture input is above a threshold level (e.g., a first threshold level). For example, if the vibration signal is below the threshold level, the wearable device (210) can determine that no gesture input has occurred.

[0152] If the vibration signal obtained by the gesture input is above a threshold level, the wearable device (210) can convert the vibration signal obtained by the gesture input into a frequency signal in operation 630. Operation 630 may correspond to operation 530 of FIG. 5. For example, the wearable device (210) can convert the vibration signal obtained in operation 520 into a frequency signal. For example, the wearable device (210) can convert the vibration signal into a frequency signal using a fast Fourier transform (FFT). For example, the wearable device (210) can convert a sound signal generated by friction occurring while moving on a touch object and an input part into a frequency signal.

[0153] According to one embodiment, the wearable device (210) can determine whether it is a multiple input signal based on information about a frequency signal converted from a vibration signal (or voice signal) in operation 640. For example, the wearable device (210) can analyze the wavelength, amplitude, and / or waveform of the frequency signal.

[0154] According to one embodiment, the wearable device (210) can determine whether the gesture input in operation 650 is a multiple object. For example, the wearable device (210) can determine whether the frequency signal is a signal composed of multiple single frequency signals based on information about the frequency signal analyzed in operation 650.

[0155] According to one embodiment, the wearable device (210) can classify frequency signals in operation 660. For example, based on the wearable device (210) determining that the frequency signal is a signal composed of a plurality of single frequency signals, the wearable device (210) can classify the frequency signal into a plurality of single frequency signals.

[0156] According to one embodiment, the wearable device (210) can identify a gesture input generated by a plurality of objects based on determining that the frequency signal in operation 670 is composed of a plurality of frequency signals.

[0157] According to one embodiment, the wearable device (210) can identify a gesture input generated by a single object based on determining that the frequency signal in operation 680 is a single frequency signal.

[0158] According to one embodiment, the wearable device (210) can identify the type of gesture input based on a raised pattern (e.g., a protrusion (370) in FIG. 7) or an intaglio pattern (e.g., a groove (380) in FIG. 8c) included in a surface pattern element (e.g., a surface pattern element (360) in FIG. 7) formed on the outer surface of the body (e.g., a body (301) in FIG. 3c) of the wearable device (210) in operation 670 and / or operation 680. For example, the surface pattern element (360) may be provided in various ways corresponding to the arrangement of the protrusion (370) and the groove (380). For example, the surface pattern element (360) may be provided in various ways corresponding to the shape of the protrusion (370) and the groove (380). Hereinafter, possible examples of the surface pattern element (360) will be described in FIGS. 6 and FIGS. 7a, FIGS. 7b, FIGS. 7c, and FIGS. 7d.

[0159] According to one embodiment, the wearable device (210) can generate a control command signal corresponding to a gesture input identified in operation 690. Operation 690 may correspond to operation 560 of FIG. 5. For example, the wearable device (210) can generate a control command signal corresponding to each different gesture input from a mapping table stored in a memory (e.g., memory (413) of FIG. 4).

[0160] According to one embodiment, the wearable device (210) can generate different control command signals corresponding to the number of input objects generating gesture inputs. For example, the wearable device (210) can generate a first type of control command signal by identifying the gesture input of a single object. For example, the wearable device (210) can generate a second type of control command signal by identifying the gesture inputs of multiple objects.

[0161] FIG. 7 illustrates the operation of receiving a gesture input for an input portion (e.g., an input portion (350) of FIG. 3c) of a wearable device (300) (e.g., a wearable device (210) of FIG. 2) according to one embodiment of the present disclosure, and the waveform of a vibration signal corresponding to the received gesture input.

[0162] FIG. 7(a) is a graph showing a vibration signal acquired by the wearable device (210) when the input object moves clockwise along the input part (350) of the wearable device (210), and FIG. 7(b) is a graph showing a vibration signal acquired by the wearable device (210) when the input object moves counterclockwise along the input part (350) of the wearable device (210).

[0163] The embodiment of FIG. 7 can be optionally combined with the embodiments of FIG. 1 to 6.

[0164] Referring to FIG. 7, the wearable device (210) can receive a user’s gesture input for an input part (e.g., the input part (350) of FIG. 3c) placed on the outer surface of a body (e.g., the body (301) of FIG. 3c). For example, the wearable device (210) can receive the gesture input by moving a part of the user’s body (e.g., the user’s finger, input object (f)) in a predetermined direction while in contact with the input part (350).

[0165] According to one embodiment, the wearable device (210) can acquire a vibration signal generated by a gesture input. For example, the wearable device (210) can acquire a vibration signal caused by vibrations that occur while moving on an input object (f) and an input part (350) when a gesture input is received from an accelerometer (e.g., accelerometer (441) of FIG. 4).

[0166] According to one embodiment, the vibration signal obtained by the wearable device (210) may be determined by a surface pattern element (360) formed on an input portion (350). For example, the surface pattern element (360) may include a protrusion (370) formed by protruding in a raised form on the input portion (350) (e.g., the protrusion (370) of FIG. 8a) or a groove formed by being sunken in a recessed form (e.g., the groove (380) of FIG. 8c).

[0167] For example, the surface pattern element (360) may be formed as either a protrusion (370) or a groove (380). For example, the surface pattern element (360) may be formed by a plurality of protrusions (370) or by a plurality of grooves (380).

[0168] For example, when a surface pattern element (360) is formed by a plurality of protrusions (370), the plurality of protrusions (370) may be arranged at different intervals. For example, among the plurality of protrusions (370) included in the surface pattern element (360), the distance between adjacent protrusions (370) may be arranged to gradually increase or decrease.

[0169] For example, when a surface pattern element (360) is formed by a plurality of protrusions (370), the plurality of protrusions (370) may be provided at different heights. For example, the plurality of protrusions (370) included in the surface pattern element (360) may be arranged so that their height gradually increases or decreases along the outer surface of the body (301).

[0170] For example, a surface pattern element (360) may be formed by combining a plurality of protrusions (370) and a plurality of grooves (380). For example, when the surface pattern element (360) is formed by combining a protrusion (370) and a groove (380), the protrusions (370) and the grooves (380) may be arranged according to a certain rule.

[0171] According to one embodiment, the wearable device (210) can acquire a vibration signal corresponding to a protrusion (370) and / or groove (380) included in a surface pattern element (360) based on receiving a gesture input, and can identify the gesture input based on the vibration signal. For example, the wearable device (210) can receive a vibration signal corresponding to the gesture input and convert the vibration signal into a frequency signal. For example, the wearable device (210) can identify the type of gesture signal by analyzing the frequency signal.

[0172] Hereinafter, in FIGS. 7 and FIGS. 8a through 8d, when the input object (f) moves clockwise on the input portion (350), the direction of movement of the input object (f) will be referred to as the d1 direction. When the input object (f) moves counterclockwise on the input portion (350), the direction of movement of the input object (f) will be referred to as the d2 direction.

[0173] FIGS. 8a, FIGS. 8b, FIGS. 8c, and FIGS. 8d illustrate a possible example of a surface pattern element (e.g., surface pattern element (360) of FIG. 7) formed in an input portion (e.g., input portion (350) of FIG. 3c) of a wearable device (300) (e.g., wearable device (210) of FIG. 2) according to one embodiment of the present disclosure, and a waveform of a vibration signal obtained by the wearable device (300) in correspondence with the surface pattern element (360).

[0174] The embodiments of FIGS. 8a, 8b, 8c, and 8d can be optionally combined with the embodiments of FIGS. 1 to 7.

[0175] The surface pattern elements (360-1; 360-2; 360-3; 360-4) illustrated in FIGS. 8a, 8b, 8c, and 8d may include protrusions (370) formed in relief and / or grooves (380) formed in intaglio on the surface of the input portion (350).

[0176] Referring to FIG. 8a, surface pattern element #1 (360-1) may include a plurality of first protrusions (370-1) (e.g., protrusion (370) of FIG. 7). The plurality of first protrusions (370-1) may be provided with the same shape.

[0177] According to one embodiment, a plurality of first protrusions (370-1) may be arranged along the input portion (350) of the wearable device (300). For example, the plurality of first protrusions (370-1) may include a first-1 protrusion (370-1a), a first-2 protrusion (370-1b), a first-3 protrusion (370-1c), a first-4 protrusion (370-1d), and a first-5 protrusion (170-1e). However, not limited to those illustrated, a larger number of first protrusions (370-1) may be provided to be arranged along the outer surface of the wearable device (300).

[0178] According to one embodiment, a plurality of first protrusions (370-1) may be arranged at a predetermined interval. For example, a plurality of first protrusions (370-1) may be arranged to have a predetermined interval between adjacent protrusions. For example, the interval between the first-1 protrusion (370-1a) and the first-2 protrusion (370-1b) may be defined as the first interval (d11). For example, the interval between the first-2 protrusion (370-1b) and the first-3 protrusion (370-1c) may be defined as the second interval (d12). For example, the interval between the first-3 protrusion (370-1c) and the first-4 protrusion (370-1d) may be defined as the third interval (d13). For example, the gap between the 1-4th projection (370-1d) and the 1-5th projection (370-1e) can be defined as the 4th gap (d14).

[0179] According to one embodiment, the first interval (d11), the second interval (d12), the third interval (d13), and the fourth interval (d14) are d11 <d12<d13<d14의 관계를 가질 수 있다. 예를 들어, 제1-1 돌기(370-1a)로부터 제1-5 돌기(370-1e)까지 시계 방향으로 배치되는 제1 돌기(370-1)들의 간격이 점점 멀어지도록 배열될 수 있다.

[0180] According to one embodiment, the wearable device (300) can acquire a vibration signal upon receiving a gesture input in response to a surface pattern element #1 (360-1) formed by a plurality of first protrusions (370-1). For example, when an input object (f) moves clockwise toward the first-fifth protrusion (370-1e) while in contact with the first-1 protrusion (370-1a), the wearable device (300) can acquire a vibration signal having a predetermined waveform from an accelerometer (e.g., the accelerometer (441) of FIG. 4).

[0181] According to one embodiment, the vibration signal may have an amplitude of approximately the same level. For example, the amplitude A1 of the vibration signal may be the same because the heights of the plurality of first protrusions (370-1) are substantially the same.

[0182] According to one embodiment, the wavelength of the vibration signal may be approximately lengthened as the input object (f) moves clockwise. For example, the wavelength of the vibration signal may be lengthened by the spacing between adjacent first protrusions among a plurality of first protrusions (370-1).

[0183] For example, when an input object (f) passes sequentially through the first-1 protrusion (370-1a) and the first-2 protrusion (370-1b), the wavelength of the vibration signal may be λ1.

[0184] For example, when an input object (f) passes sequentially through the first-2 protrusion (370-1b) and the first-3 protrusion (370-1c), the wavelength of the vibration signal may be λ2.

[0185] For example, when an input object (f) passes sequentially through the first-3rd protrusion (370-1c) and the first-4th protrusion (370-1d), the wavelength of the vibration signal may be λ3.

[0186] For example, when an input object (f) passes sequentially through the first-4th protrusion (370-1d) and the first-5th protrusion (370-1e), the wavelength of the vibration signal may be λ4.

[0187] According to one embodiment, the wavelength of the vibration signal generated according to the movement of the input object (f) may have the relationship λ1<λ2<λ3<λ4.

[0188] Referring to FIG. 8b, surface pattern element #2 (360-2) may include a plurality of second protrusions (370-2) (e.g., protrusion (370) of FIG. 7).

[0189] According to one embodiment, a plurality of first protrusions (370-1) may be arranged along the input portion (350) of the wearable device (300). For example, a plurality of second protrusions (370-2) may include a second-1 protrusion (370-2a), a second-2 protrusion (370-2b), a second-3 protrusion (370-2c), a second-4 protrusion (370-2d), and a second-5 protrusion (170-2e). However, not limited to what is illustrated, a larger number of second protrusions (370-2) may be provided to be arranged along the outer surface of the wearable device (300).

[0190] According to one embodiment, a plurality of second protrusions (370-2) may be arranged at a predetermined interval. For example, a plurality of second protrusions (370-2) may be arranged to have substantially the same interval between adjacent protrusions.

[0191] According to one embodiment, each of the plurality of second protrusions (370-2) may be provided at a different height. For example, the height of the second protrusion (370-2) may be defined as the distance from the outer surface to one end of the plurality of second protrusions (370-2).

[0192] According to one embodiment, the height of the second-1 protrusion (370-2a) can be defined as the first height (h21). The height of the second-2 protrusion (370-2b) can be defined as the second height (h22). The height of the second-3 protrusion (370-2c) can be defined as the third height (h23). The height of the second-4 protrusion (370-2d) can be defined as the fourth height (h24). The height of the second-5 protrusion (370-2e) can be defined as the fifth height (h25).

[0193] According to one embodiment, the first height (h21), the second height (h22), the third height (h23), the fourth height (h24), and the fifth height (h25) may have the relationship h21 > h22 > h23 > h24 > h25. For example, the heights of the first protrusions (370-1), which are arranged clockwise from the second-1 protrusion (370-2a) to the second-5 protrusion (370-2e), may be arranged so that they gradually decrease.

[0194] According to one embodiment, the wearable device (300) can acquire a vibration signal upon receiving a gesture input in response to a surface pattern element #2 (360-2) formed by a plurality of second protrusions (370-2). For example, when an input object (f) is in contact with the second-1 protrusion (370-2a) and moves clockwise toward the second-5 protrusion (370-2e), the wearable device (300) can acquire a vibration signal having a predetermined waveform from an accelerometer (e.g., the accelerometer (441) of FIG. 4).

[0195] According to one embodiment, the vibration signals may have approximately the same wavelength. For example, the wavelength of the vibration signals may be the same because the spacing between adjacent second protrusions among a plurality of second protrusions (370-2) is substantially the same.

[0196] According to one embodiment, the amplitude of the vibration signal may decrease approximately as the input object (f) moves in a clockwise direction. For example, the amplitude of the vibration signal may decrease as the height of the clockwisely arranged protrusions included in the plurality of first protrusions (370-1) decreases.

[0197] Referring to FIG. 8c, surface pattern element #3 (360-3) may include a plurality of third protrusions (370-3) (e.g., protrusion (370) of FIG. 7) or a plurality of third grooves (380-3) (e.g., groove (380) of FIG. 7).

[0198] According to one embodiment, a plurality of third protrusions (370-3) may be arranged along the input portion (350) of the wearable device (300). For example, the plurality of third protrusions (370-3) may include a third-1 protrusion (370-3a), a third-2 protrusion (370-3b), a third-3 protrusion (370-3c), and a third-4 protrusion (370-3d). For example, the plurality of third grooves (380-3) may include a third-1 groove (380-3a), a third-2 groove (380-3b), a third-3 groove (380-3c), a third-4 groove (380-3d), and a fifth groove (380-3e). However, not limited to those illustrated, a plurality of third protrusions (370-3) and a plurality of third grooves (380-3) may be provided in a greater number to be arranged along the outer surface of the wearable device (300).

[0199] According to one embodiment, a plurality of third protrusions (370-3) and a plurality of third grooves (380-3) may be arranged at a predetermined interval. For example, the plurality of third protrusions (370-3) and the plurality of third grooves (380-3) may be arranged so that adjacent components have substantially the same interval.

[0200] According to one embodiment, a plurality of third protrusions (370-3) and a plurality of third grooves (380-3) may be arranged according to a certain rule. For example, along the input portion (350), they may be arranged in a clockwise order of a third-1 protrusion (370-3a), a third-1 groove (380-3a), a third-2 protrusion (370-3b), a third-2 groove (380-3b), a third-3 groove (380-3c), a third-3 protrusion (370-3c), a third-4 protrusion (370-3d), a third-4 groove (380-3d), and a third-5 groove (380-3e).

[0201] According to one embodiment, the wearable device (300) can acquire a vibration signal upon receiving a gesture input in response to a surface pattern element #3 (360-3) formed by a plurality of third protrusions (370-3) and a plurality of third grooves (380-3). For example, when an input object (f) moves clockwise toward the third-fifth groove (380-3e) while in contact with the third-third protrusion (370-3c), the wearable device (300) can acquire a vibration signal having a predetermined waveform from an accelerometer (e.g., the accelerometer (441) of FIG. 4).

[0202] According to one embodiment, the vibration signal may include a first vibration signal, which is a vibration signal generated when the input object (f) moves to the third-fourth protrusion (370-3d) while in contact with the third-third protrusion (370-3c), and a second vibration signal, which is a vibration signal generated when the input object (f) moves from the third-fourth groove (380-3d) to the third-fifth groove (380-3e).

[0203] According to one embodiment, the wavelength (λ31) of the first vibration signal may be shorter than the wavelength (λ32) of the second vibration signal. For example, because the distance between the third-3 protrusion (370-3c) and the third-4 protrusion (370-3d) is less distant than the distance between the third-4 groove (380-3d) and the third-5 groove (380-3e), the wavelength (λ31) of the first vibration signal may be shorter than the wavelength (λ32) of the second vibration signal.

[0204] According to one embodiment, the amplitude (A31) of the first vibration signal may be greater than the amplitude (A32) of the second vibration signal. For example, because the height of the third projection (370-3) is higher than the height of the third groove (380-3), the amplitude (A31) of the first vibration signal may be greater than the amplitude (A32) of the second vibration signal.

[0205] Referring to FIG. 8d, surface pattern element #4 (360-4) may include a plurality of fourth protrusions (370-4) (e.g., protrusion (370) of FIG. 7).

[0206] According to one embodiment, a plurality of fourth protrusions (370-4) may include protrusions of substantially the same shape. For example, the fourth protrusion (370-4) may include a fourth-1 protrusion (370-4a) and a fourth-2 protrusion (370-4b).

[0207] According to one embodiment, the fourth projection (370-4) may have inclined surfaces having different angles of inclination. For example, the fourth-1 projection (370-4a) included in the fourth projection (370-4) may include a first inclined surface (371-4a) and a second inclined surface (373-4a) positioned to face the first inclined surface (371-4a). For example, the fourth-2 projection (370-4b) included in the fourth projection (370-4) may include a third inclined surface (371-4b) and a fourth inclined surface (373-4b) positioned to face the third inclined surface (371-4b).

[0208] According to one embodiment, the first angle of inclination, which is an acute angle formed by the first inclined surface (371-4a) with the surface of the input portion (350), may be greater than the second angle of inclination, which is an acute angle formed by the second inclined surface (373-4a) with the surface of the input portion (350). According to one embodiment, the third angle of inclination, which is an acute angle formed by the third inclined surface (371-4b) with the surface of the input portion (350), may be greater than the fourth angle of inclination, which is an acute angle formed by the fourth inclined surface (373-4b) with the surface of the input portion (350). The first angle of inclination and the third angle of inclination may be substantially the same, and the second angle of inclination and the fourth angle of inclination may be substantially the same.

[0209] According to one embodiment, since each inclined surface of the fourth projection (370-4) has a different angle of inclination, the wearable device (300) can obtain different vibration signals corresponding to the direction of the gesture input.

[0210] According to one embodiment, the wearable device (300) can acquire a first vibration signal (s1) due to a gesture input generated by the input object (f) moving clockwise. The wearable device (300) can acquire a second vibration signal (s2) due to a gesture input generated by the input object (f) moving counterclockwise.

[0211] According to one embodiment, the amplitude (A41) of the first vibration signal (s1) may be greater than the amplitude (A42) of the second vibration signal (s2). For example, the amplitude (A41) of the first vibration signal (s1) may be greater than the amplitude (A42) of the second vibration signal (s2) because the first angle of inclination (or the third angle of inclination), which is the angle formed by the first inclined surface (371-4a) (or the third inclined surface (371-4b)) with the surface of the input part (350), is greater than the second angle of inclination (or the fourth angle of inclination), which is the angle formed by the second inclined surface (373-4a) (or the fourth inclined surface (373-4b)) with the surface of the input part (350).

[0212] FIG. 9 schematically illustrates the operation of a wearable device (e.g., the wearable device (210) of FIG. 2) according to one embodiment of the present disclosure classifying a signal (e.g., a vibration signal) generated by a gesture input into a plurality of frequency signals.

[0213] Referring to FIG. 9, the wearable device (210) can acquire a vibration signal by gesture input. For example, the wearable device (210) can acquire a vibration signal according to the gesture input from an accelerometer (e.g., the accelerometer (441) of FIG. 4).

[0214] According to one embodiment, the wearable device (210) can convert a vibration signal into a frequency signal (S). For example, the wearable device (210) can convert the vibration signal into a frequency signal (S) using a Fast Fourier Transform (FFT). For example, the wearable device (210) can convert a vibration signal in the time domain into a frequency signal in the frequency domain using a Fast Fourier Transform.

[0215] According to one embodiment, the wearable device (210) can identify the type of gesture based on a frequency signal (S). For example, the wearable device (210) can determine the direction of movement of an input object generating a gesture input or the number of input objects generating a gesture input based on the wavelength, amplitude, and / or waveform of the frequency signal.

[0216] According to one embodiment, a wearable device (210) can classify a frequency signal (S) resulting from a gesture input generated by multiple input objects into a plurality of single frequency signals (S1, S2). For example, the wearable device (210) can perform a filtering operation on the frequency signal (S). The wearable device (210) can filter the frequency signal (S) into a plurality of single frequency signals (S1, S2) using a high-pass filter (HPF) or a low-pass filter (LPF). For example, the frequency signal (S) may include a first single frequency signal (S1) of a high-frequency signal classified by a high-pass filter, or a second single frequency signal (S2) of a low-frequency signal classified by a low-pass filter. However, not limited to what is illustrated, the wearable device (210) can classify the frequency signal (S) in correspondence with the number of input objects.

[0217] According to one embodiment, the wearable device (210) can determine whether the gesture signal is generated by a single object or by a plurality of objects based on classified frequency signals (S1, S2). For example, the wearable device (210) can generate different control command signals corresponding to the type of gesture signal.

[0218] FIGS. 10a to 10h illustrate gesture inputs for a wearable device (300) (e.g., the wearable device (210) of FIG. 2) according to one embodiment of the present disclosure, by type.

[0219] FIGS. 10a and 10b illustrate gesture input by a single object (e.g., one finger), FIGS. 10c, 10d, 10e, and 10f illustrate gesture input by two objects (e.g., two fingers), and FIGS. 10g and 10h illustrate gesture input by three objects (e.g., three fingers). The wearable device (300) can generate different types of control command signals depending on the number of objects generating the gesture input. For example, the wearable device (300) can generate a first type of control command signal by gesture input of a single object. For example, the wearable device (300) can generate a second type of control command signal by gesture input of multiple objects. For example, the second type of control command signal may include a second-1 type of control command signal generated by two input objects and a second-2 type of control command signal generated by three input objects.

[0220] The embodiments of FIGS. 10a to 10h can be optionally combined with the embodiments of FIGS. 1 to 9.

[0221] Referring to FIGS. 10a through 10h, the wearable device (210) can identify the type of gesture input received by an input part (e.g., the input part (350) of FIG. 3c). For example, the wearable device (210) can acquire a vibration signal generated by the gesture input, convert the acquired vibration signal into a frequency signal, and identify the type of gesture input corresponding to the converted frequency signal. The wearable device (210) can identify each gesture input of FIGS. 10a through 10h, which will be described later, and generate a control command signal corresponding to each different gesture input.

[0222] The gesture inputs described in FIGS. 10a through 10h are illustrated with the wearable device (210) being worn on the user's right index finger, but are not limited to what is illustrated. For example, the gesture inputs described below may be generated by the movement of an input object (e.g., a part of the user's body, or another finger not wearing the wearable device (210)) with respect to an input part included in the wearable device (210) (e.g., the input part (350) in FIG. 3c).

[0223] Referring to FIGS. 10a and 10b, a wearable device (210) can obtain a gesture input by one input object (f). For example, the gesture input may include a first gesture input (G1) generated by one input object (f) moving counterclockwise and a second gesture input (G2) generated by one input object (f) moving clockwise.

[0224] According to one embodiment, a first gesture input (G1) may be generated by moving a single input object (f) counterclockwise on an input portion (350) included in a wearable device (210). For example, the first gesture input (G1) may be generated by moving the user's right thumb counterclockwise from a specific point on the input portion (350) of the wearable device (210).

[0225] According to one embodiment, a second gesture input (G2) may be generated by moving a single input object (f) clockwise on an input portion (350) included in a wearable device (210). For example, a first gesture input (G1) may be generated by moving the user's right thumb clockwise from a specific point on the input portion (350) of the wearable device (210).

[0226] Referring to FIGS. 10c, 10d, 10e, and 10f, a wearable device (210) can obtain gesture input by two input objects (f1, f2). For example, the two input objects (f1, f2) may include a first input object (f1) and a second input object (f2). For example, the gesture input may include a third gesture input (G3) generated by both of the two input objects (f1, f2) moving counterclockwise, and a fourth gesture input (G2) generated by the two input objects (f1, f2) moving clockwise. For example, the gesture input may include a fifth gesture input (G5) generated by the two input objects (f1, f2) moving away from each other, and a sixth gesture input (G6) generated by the two input objects (f1, f2) moving closer to each other.

[0227] According to one embodiment, a third gesture input (G3) may be generated by both input objects (f1, f2) moving counterclockwise on an input portion (350) included in a wearable device (210). For example, the third gesture input (G3) may be generated by moving the user's left thumb and the user's left index finger counterclockwise from a specific point on the input portion (350) of the wearable device (210).

[0228] According to one embodiment, a fourth gesture input (G4) may be generated by both input objects (f1, f2) moving clockwise on an input portion (350) included in a wearable device (210). For example, the fourth gesture input (G4) may be generated by moving the user's left thumb and the user's left index finger clockwise from a specific point on the input portion (350) of the wearable device (210).

[0229] According to one embodiment, the fifth gesture input (G5) may be generated by two input objects (f1, f2) located at adjacent positions on the input portion (350) included in the wearable device (210) moving away from each other. For example, the fifth gesture input (G5) may be generated by the user's left thumb and the user's left index finger moving in opposite directions away from each other while located adjacently on the input portion (350) of the wearable device (210).

[0230] According to one embodiment, the sixth gesture input (G6) may be generated by moving two input objects (f1, f2) located on an input portion (350) included in the wearable device (210) so that they come closer to each other. For example, the sixth gesture input (G6) may be generated by moving the user's left thumb and the user's left index finger in opposite directions so that they come closer to each other on the input portion (350) of the wearable device (210).

[0231] Referring to FIG. 10g and FIG. 10h, a wearable device (210) can obtain gesture input by three input objects (f1, f2, f3). For example, the three input objects (f1, f2, f3) may include a first input object (f1), a second input object (f2), and a third input object (f3). For example, the gesture input may include a seventh gesture input generated by all three input objects (f1, f2, f3) moving counterclockwise, and an eighth gesture input generated by all three input objects (f1, f2, f3) moving clockwise.

[0232] According to one embodiment, the seventh gesture input (G7) may be generated by all three input objects (f1, f2, f3) moving counterclockwise on the input portion (350) included in the wearable device (210). For example, the seventh gesture input (G3) may be generated by the user's left thumb, the user's left index finger, and the user's left middle finger moving counterclockwise from a specific point on the input portion (350) of the wearable device (210) while separated by a predetermined distance.

[0233] According to one embodiment, the eighth gesture input (G8) may be generated by all three input objects (f1, f2, f3) moving clockwise on an input portion (350) included in the wearable device (210). For example, the eighth gesture input (G3) may be generated by the user's left thumb, the user's left index finger, and the user's left middle finger moving clockwise from a specific point on the input portion (350) of the wearable device (210) while separated by a predetermined distance.

[0234] FIG. 11 illustrates a wearable device (300) (e.g., wearable device (210) of FIG. 2) in which surface pattern elements (360; 360L, 360R) (e.g., surface pattern elements (360) of FIG. 7) are symmetrically arranged, according to one embodiment of the present disclosure.

[0235] Referring to FIG. 11, surface pattern elements (360) included in the wearable device (300) can be arranged symmetrically with respect to a virtual auxiliary line (L). For example, the surface pattern elements (360) can be arranged symmetrically left and right with respect to an auxiliary line (L) passing through a reference point (P) and the center (C) of an opening formed in the wearable device (300).

[0236] According to one embodiment, the surface pattern element (360) may include a first surface pattern element (360L) positioned on the left side of the wearable device (300) and a second surface pattern element (360R) positioned on the right side of the wearable device (300). The first surface pattern element (360L) and the second surface pattern element (360R) may be positioned symmetrically with respect to a reference line (L).

[0237] According to one embodiment, the wearable device (300) can identify the wearing direction based on a first surface pattern element (360L) and a second surface pattern element (360R). For example, the wearable device (300) can guide the user to wear it so that the reference point (P) aligns with the center of the finger facing the user's palm. For example, the wearable device (300) can receive an initial gesture input from the user based on symmetrically arranged surface pattern elements (360) and identify whether the wearable device (300) is worn in the forward direction based on the received gesture input. In FIGS. 12, 13a, 13b, and 13c to be described later, information for identifying the direction in which the wearable device (300) is worn and guiding the user to wear the wearable device (300) in the forward direction will be explained.

[0238] FIG. 12 illustrates an exemplary user interface that guides a method of wearing a wearable device (e.g., the wearable device (210) of FIG. 2) according to one embodiment of the present disclosure.

[0239] The embodiment of FIG. 12 can be optionally combined with the embodiments of FIG. 1 to FIG. 11.

[0240] Referring to FIG. 12, an external terminal (220) (e.g., the external terminal (220) of FIG. 2) may display a user interface on a display that guides how to wear the wearable device (210). For example, the external terminal (220) may receive information about how to wear the wearable device (210) from the wearable device (210) in response to identifying that it is connected to the wearable device (210). For example, the external terminal (220) may receive information about how to wear the wearable device (210) from a server (e.g., the server (240) of FIG. 2).

[0241] According to one embodiment, a first user interface (1210) displayed on the display of an external terminal (220) may include information regarding the wearing direction of the wearable device (210). For example, it may include information guiding the wearer to be worn with a reference point (e.g., reference point (P) in FIG. 11) placed on the surface of the wearable device (210) facing the palm. For example, when the wearable device (210) is worn in the forward direction, it may generate a control command signal corresponding to the user's intended gesture input. For example, when the wearable device (210) is worn in the reverse direction, it may generate a control command signal different from the control command signal corresponding to the user's intended gesture input.

[0242] According to one embodiment, the first user interface (1210) displayed on the display of the external terminal (220) may include information regarding the wearing position of the wearable device (210). For example, it may include information regarding the appropriate position of the user's finger on which the wearable device (210) is worn. Because the wearable device (210) is worn on the appropriate position of the user's finger, the biosignal sensing unit (e.g., the biosignal sensing unit (343) of FIG. 3c) included in the wearable device (210) can appropriately sense the user's biosignal information.

[0243] According to one embodiment, a second user interface (1220) displayed on the display of an external terminal (220) may include information included in the first user interface (1210) in a diagrammatic form. For example, the second user interface (1220) may include information diagrammatically representing the wearing direction and / or wearing position of the wearable device (210).

[0244] FIGS. 13a, FIGS. 13b, and FIGS. 13c illustrate, exemplarily, a user interface for guiding a method of wearing a wearable device (e.g., the wearable device (210) of FIG. 2) and a user interface for identifying the wearing direction of the wearable device (210) according to one embodiment of the present disclosure.

[0245] The embodiments of FIGS. 13a to 13c can be optionally combined with the embodiment of FIG. 12.

[0246] Referring to FIGS. 13a through 13c, user interfaces displayed on the display of an external terminal (220) (e.g., the external terminal (220) of FIG. 2) may include information for guiding how to wear the wearable device (210) and information for identifying whether it is worn in the correct orientation.

[0247] Referring to FIG. 13a, the external terminal (220) can display first information (1311) indicating that the user interface guides the wearing method of the wearable device (210) on the display.

[0248] According to one embodiment, the external terminal (220) may display the first information (1311) in a schematic form as second information (1313) on a display. For example, the second information (1313) may be information instructing the wearable device (210) to be worn such that the biosignal detection unit (e.g., the biosignal detection unit (343) of FIG. 3c) is positioned on the inner side of the user's finger.

[0249] According to one embodiment, the external terminal (220) may display a third information (1315) containing details of the second information (1313) on a display. For example, the third information (1315) may be information instructing the wearable device (210) to be worn such that the biosignal detection unit (343) is positioned on the inner side of the user's finger.

[0250] Referring to FIGS. 13b and 13c, the external terminal (220) may display a user interface requesting a gesture input (e.g., a sample gesture input) from the user in order to identify the direction in which the wearable device (210) is worn.

[0251] According to one embodiment, in order to identify whether the wearable device (210) is worn in the correct direction on the user's finger, an external terminal (220) may display a user interface requesting a gesture input from the user on a display. For example, the external terminal (220) may display information requesting a first gesture input (e.g., the first gesture input (G1) of FIG. 10a) or a second gesture input (e.g., the second gesture input (G2) of FIG. 10b) from the wearable device (210) on a display. For example, the first gesture input and / or the second gesture input may be sample gestures for identifying the wearing direction of the wearable device (210).

[0252] Referring to FIG. 13b, the external terminal (220) can display first information (1321) indicating that the user interface requests a first gesture input (G1) to the wearable device (210) on the display.

[0253] According to one embodiment, the external terminal (220) may display the first information (1321) in a diagrammatic form as second information (1323) on a display. For example, the second information (1323) may be information that instructs the input part of the wearable device (210) (e.g., the input part (350) of FIG. 3c) to generate a first gesture signal (G1) for swiping an input object (e.g., the input object (f) of FIG. 7) in a counterclockwise direction (or downward direction).

[0254] According to one embodiment, the external terminal (220) may display third information (1325) indicating that the wearable device (210) is detecting the wearing direction on the display.

[0255] Referring to FIG. 13c, the external terminal (220) can display first information (1331) indicating that the user interface requests a second gesture input (G2) to the wearable device (210) on the display.

[0256] According to one embodiment, the external terminal (220) may display the first information (1331) in a diagrammatic form as a second information (1333) on a display. For example, the second information (1333) may be information that instructs the input portion (350) of the wearable device (210) to generate a second gesture signal (G2) for swiping an input object (e.g., input object (f) of FIG. 7) in a clockwise direction (or upward direction).

[0257] According to one embodiment, the external terminal (220) may display third information (1335) indicating that the wearable device (210) is detecting the wearing direction on the display.

[0258] Referring to FIGS. 12, FIGS. 13a, FIGS. 13b, and FIGS. 13c, a wearable device (210) detects that it is being worn, receives input of a user's gesture (e.g., a sample gesture) while being worn, and can identify the received gesture input. For example, the wearable device (210) can compare the requested gesture input with the identified gesture input and identify whether it is being worn in the forward direction.

[0259] According to one embodiment, if the wearable device (210) determines that the requested gesture input and the identified gesture input are different, it may display a user interface requesting the wearable device (210) to be re-worn to an external terminal (220).

[0260] According to one embodiment, if the wearable device (210) determines that the requested gesture input and the identified gesture input are the same, the wearable device (210) can determine that it is worn in a forward direction.

[0261] According to one embodiment, when a gesture input occurs, the wearable device (210) may identify the type of gesture input based on a vibration signal and / or a frequency signal, and generate a control command signal corresponding to the identified type of gesture input. The wearable device (210) may generate a control command signal to control an external terminal (220) and / or an external device (e.g., the external device (230) of FIG. 2) and transmit the generated control command signal to the external terminal (220) and / or the external device (230). In FIG. 14a and below, an embodiment in which the external terminal (220) or the external device (230) is controlled through a control command signal generated from the wearable device (210) will be described.

[0262] FIGS. 14a and FIGS. 14b illustrate, in an exemplary manner, an operation in which a wearable device (210) (e.g., the wearable device (210) of FIG. 2) controls an external terminal (220) (e.g., the external terminal (220) of FIG. 2) through gesture input, according to one embodiment of the present disclosure.

[0263] FIGS. 14a and FIGS. 14b illustrate an example of a user interface in which a wearable device (210) receives a gesture input (e.g., a first gesture input (G1) or a second gesture input (G2) of FIG. 10a), generates a control command signal in response to the gesture input (G1, G2), and transmits it to an external terminal (220), thereby allowing the external terminal (220) to perform a control operation in response to the control command signal.

[0264] Referring to FIGS. 14a and 14b, the wearable device (210) can generate a control command signal in response to receiving a gesture input. For example, the wearable device (210) can identify the received gesture input based on a vibration signal and a frequency signal. The wearable device (210) can generate a control command signal in response to the type of the identified gesture input.

[0265] According to one embodiment, the wearable device (210) can identify that it has received a first gesture input (G1) and generate a first control command signal. For example, the first control command signal may be a control command signal that moves the screen displayed on the display of the external terminal (220) downward.

[0266] According to one embodiment, the wearable device (210) can generate a second control command signal by identifying that it has received a second gesture input (G2). For example, the second control command signal may be a control command signal that moves the screen displayed on the display of the external terminal (220) upward.

[0267] However, the first control command signal and the second control command signal may be expressed in various forms corresponding to a mapping table previously stored in the external terminal (220), not limited to those depicted in FIG. 14a and FIG. 14b. For example, the first control command signal and the second control command signal may be control command signals for changing a selected object among the objects (or icons) displayed on the display. For example, the first control command signal and the second control command signal may be control command signals for moving the selected object in a horizontal direction corresponding to the direction in which the objects are arranged, or control command signals for moving it in a vertical direction.

[0268] FIGS. 15, 16, and 17 illustrate, in an exemplary manner, an operation in which a wearable device (210) (e.g., the wearable device (210) of FIG. 2) controls an external terminal (220) (e.g., the external terminal (220) of FIG. 2) and / or an external device (230) (e.g., the external device (230) of FIG. 2) through a gesture input, according to one embodiment of the present disclosure.

[0269] FIG. 15 illustrates, in an exemplary manner, an operation in which a wearable device (210) generates a control command signal to change the playback timing of a video being played on an external device (230) through a gesture input (e.g., the third gesture input (G3) of FIG. 10c or the fourth gesture input (G4) of FIG. 10d).

[0270] FIG. 16 illustrates, in an exemplary manner, an operation in which a wearable device (210) generates a control command signal to change the volume of a video being played on an external device (230) through a gesture input (e.g., the fifth gesture input (G5) of FIG. 10e or the sixth gesture input (G6) of FIG. 10f).

[0271] FIG. 17 illustrates, in an exemplary manner, an operation in which a wearable device (210) generates a control command signal to turn on or off the power of an external device (230) through a gesture input (e.g., the eighth gesture input (G8) of FIG. 10h).

[0272] Not limited to those illustrated in FIGS. 15 to 17, an external terminal (220) or an external device (230) may perform a control operation corresponding to a control command signal based on a pre-stored mapping table.

[0273] Referring to FIG. 15, the wearable device (210) can generate a control command signal to change the playback timing of a video being played on an external device (230) through a gesture input (e.g., the third gesture input (G3) of FIG. 10c or the fourth gesture input (G4) of FIG. 10d).

[0274] Referring to FIG. 15 (a), the wearable device (210) can identify that it has received a third gesture input (G3) and generate a third control command signal. For example, the third control command signal may be a fast forward control command signal that moves the viewpoint of an image displayed on the display of an external device (230) forward.

[0275] Referring to FIG. 15(b), the wearable device (210) can identify that it has received a fourth gesture input (G4) and generate a fourth control command signal. For example, the fourth control command signal may be a control command signal that rewinds the viewpoint of an image displayed on the display of an external device (230).

[0276] Referring to FIG. 16, the wearable device (210) can generate a control command signal to change the volume of a video being played on an external device (230) through a gesture input (e.g., the fifth gesture input (G5) of FIG. 10e or the sixth gesture input (G6) of FIG. 10f).

[0277] Referring to FIG. 16(b), the wearable device (210) can identify that it has received a fifth gesture input (G5) and generate a fifth control command signal. For example, the fifth control command signal may be a control command signal that reduces the volume of an image displayed on the display of an external device (230).

[0278] Referring to FIG. 16 (a), the wearable device (210) can identify that it has received a sixth gesture input (G6) and generate a sixth control command signal. For example, the sixth control command signal may be a control command signal that increases the volume of an image displayed on the display of an external device (230).

[0279] Referring to FIG. 17, the wearable device (210) can generate a control command signal to turn on or off the power of an external device (230) through a gesture input (e.g., the eighth gesture input (G8) of FIG. 10h).

[0280] According to one embodiment, the wearable device (210) may generate a seventh control command signal by identifying that it has received an eighth gesture input (G8). For example, the seventh control command signal may be a control command signal to turn on or off the power of an external device (230).

[0281] Not limited to what is illustrated, the wearable device (210) may generate a seventh control command by identifying that it receives a seventh gesture input (G7). For example, the wearable device (210) may generate a seventh control command by receiving gesture input through three input objects. For example, the wearable device (210) may generate a seventh control command signal by rotating the three input objects counterclockwise or clockwise.

[0282] According to one embodiment, the external terminal (220) and / or external device (230) may have operations performed according to each control command signal mapped in the form of a database. For example, the control operation according to each control command signal (e.g., first control command signal to seventh control command signal) may be set by taking into account the characteristics of the function activated by the control command signal.

[0283] For example, a control command signal mapped to each gesture input can be determined by the frequency of use of the action performed by the control command signal. For instance, if the frequency of use of the action performed by the control command signal is high, the input gesture by a single input object can be configured to be mapped to the control command signal.

[0284] For example, the control command signal mapped to each gesture input can be determined by considering the severity of potential malfunctions caused by the control command signal. For instance, if a function activated by the control command signal malfunctions and causes a serious error, the control command signal may be configured to be mapped to input gestures by multiple input objects.

[0285] For example, the control command signal mapped to each gesture input can be determined by considering the possibility that the user may recognize a malfunction when the control command signal occurs. For instance, if a malfunction in a function activated by the control command signal is easily recognized by the user, the control command signal may be configured to be mapped to an input gesture by a single input object.

[0286] A wearable device (210; 300) (e.g., electronic device (101) of FIG. 1) according to one embodiment of the present disclosure can identify a gesture input using an acceleration sensor (e.g., acceleration sensor (441) of FIG. 4) and generate a different control command signal in response to the identified gesture input.

[0287] A wearable device (210; 300) according to one embodiment of the present disclosure can identify a gesture input based on a vibration signal received by a surface pattern element (360) formed on the outer surface of a body (301).

[0288] A wearable device (210; 300) according to one embodiment of the present disclosure can identify gesture input using only an accelerometer (441) without a separate sensor.

[0289] A wearable device (210; 300) according to one embodiment of the present disclosure can provide an aesthetic appearance of the wearable device (210; 300) by a surface pattern element (360) formed by a protrusion (370) and / or a groove (380).

[0290] The effects obtainable from the present disclosure are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which the present disclosure belongs from the description below.

The above instructions, when executed individually or collectively by the at least one processor (411), may cause the wearable device (210; 300) to acquire a vibration signal generated by the gesture input (520; 610), respond to the fact that the intensity of the vibration signal is higher than a first threshold level (620), convert the vibration signal into a frequency signal (530; 630), identify the gesture input based on the converted frequency signal (550), and generate a control signal based on the location of occurrence of the identified gesture input or the direction of movement of the gesture input (560; 680, 690). The outer frame (310) may include a surface pattern element (360) comprising a plurality of protrusions (370) protruding from the outer surface of the body (301).

The plurality of protrusions (370-1; 370-1a, 370-1b, 370-1c, 370-1d, 370-1e) may be arranged such that the spacing between adjacent protrusions increases along the outer surface of the body (301).

[0293] In a wearable device (210) according to one embodiment of the present disclosure, the surface pattern element (360-2) may include a plurality of protrusions (370-2; 370-2a, 370-2b) having different heights. The height of adjacent protrusions among the plurality of protrusions (370-2; 370-2a, 370-2b) may be arranged to increase along the outer surface of the body.

[0294] In a wearable device (210) according to one embodiment of the present disclosure, the plurality of protrusions (370-4; 370-4a, 370-4b) included in the surface pattern element (360-4) may include a first inclined surface (371-4a, 371-4b) and a second inclined surface (373-4a, 373-4b) facing the first inclined surface (371-4a; 371-4b). The first inclination angle formed by the first inclined surface (371-4a, 371-4b) with the surface of the body (301) may be different from the second inclination angle formed by the second inclined surface (373-4a, 373-4b) with the surface of the body (301).

[0295] In a wearable device (210) according to one embodiment of the present disclosure, the surface pattern element (360) may include one or more grooves (380; 380-3a, 380-3b) formed by being recessed from the outer surface of the body (301).
