Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic perspective view of a band-shaped sensor according to an embodiment.

Referring to FIG. 1, the band-shaped sensor may have a band shape. Both ends of the band-type sensor may be in contact with each other or a part of them may be overlapped to form a band shape.

In the band-type sensor, the valid areas AA1 and AA2 and the non-valid area UA can be defined. The valid area may include a first valid area AA1 and a second valid area AA2.

in details. In the band-type sensor, the first effective area AA1 and the second effective area AA2 may be spaced apart from each other. At this time, a non-effective area UA is disposed between the first effective area AA1 and the second effective area AA2 to form a band shape.

Also, when the band-type sensor is in the shape of a band, the inner surface IS of the first effective area AA1 and the inner surface IS of the second effective area AA2 can face each other.

The remaining area excluding the first valid area AA1 and the second valid area AA2 may be defined as the ineffective area UA.

A display may be displayed in the first valid area AA1. In the first effective area AA1, a touch sensor capable of sensing a touch may be disposed. For example, a display is displayed in the first valid area AA1, and a touch interface capable of controlling the wearable device by a touch according to the display display can be provided.

For example, the touch sensor may be disposed toward the outer side (OS) side of the first effective area AA1. In detail, when the band-type sensor is in contact with or overlapped with both ends of the band-type sensor, it is possible to sense a touch input to the outer side OS of the first effective area AA1 that the user can see.

The second effective area AA2 may be a gesture sensor capable of sensing a user's gesture. For example, when a user wears a band-type sensor, at least a portion of the second effective area AA2 may contact the user's wear area to sense the user's gesture.

The gesture sensor may be disposed toward the inner surface IS of the second effective area AA2. In detail, when the user wears the band-type sensor, the gesture sensor can sense the user's gesture on the inner surface (IS) contacting the wearer's part.

Hereinafter, a specific configuration of the band-type sensor will be described with reference to Figs. 2 to 17. Fig.

FIG. 5 is a plan view of the band-type sensor according to the embodiment, FIG. 6 is a rear view of the band-type sensor according to the embodiment, and FIG. 7 is a cross-sectional view taken along the line X-X 'in FIG.

2 to 10, the band-shaped sensor according to the embodiment may include a substrate 100, a touch sensor, and a gesture sensor.

First, as shown in FIG. 2, the substrate 100 may have a shape corresponding to the shape of the band-shaped sensor. That is, the substrate 100 may have a band shape. Therefore, the substrate 100 has a first effective area AA1, a second effective area AA2, and a non-effective area UA disposed between both sides of the first effective area AA1 and the second effective area AA2. .

The integrated substrate 100 may be disposed in the first effective area AA1 and the second effective area AA2 to implement a touch sensor and a gesture sensor on the single substrate 100. [ Alternatively, as shown in Fig. 3, the substrate 100 of another embodiment corresponds to the shape of the band-shaped sensor, but a part thereof may be omitted. For example, the substrate 100 may include a first effective area AA1, a second effective area AA2, and a non-effective area UA disposed between one side of the first effective area AA2 and the first effective area AA1. ).

The substrate 100 may include both the first effective area AA1 and the second effective area AA2 so that the touch sensor and the gesture sensor may be disposed on the single substrate 100. [ In addition, the substrate 100 may reduce the unit cost by omitting a part of the unnecessary ineffective area UA. Alternatively, as shown in FIG. 4, the substrate 100 of another embodiment may include at least one substrate 100. For example, the substrate 100 may include a second substrate 120 disposed in a second effective area AA2. In addition, the substrate 100 may include a first substrate 110 disposed in a first effective area AA1.

When the substrate 100 includes both the first substrate 110 and the second substrate 120, the first substrate 110 and the second substrate 120 may be spaced apart from each other.

In the case where the substrate 100 is the first substrate 110 or the second substrate 120, the band-like sensor may be disposed in only a part of the wearable device (e.g., Fig. 18). For example, when the substrate 100 is the first substrate 110, the touch sensor may be disposed in a region corresponding to the display unit in the wearable device. When the substrate 100 is the second substrate 120, the gesture sensor may be disposed in a region corresponding to the band portion of the wearable device.

At this time, the band-type sensor may include only the gesture sensor.

The entire substrate 100 may be formed of a single material. Alternatively, the substrate 100 may be formed of a different material for each region. For example, in the substrate 100, the first effective area AA1 and the other area may be formed of different materials.

Further, the substrate 100 may be formed to be transparent. In the case of the first effective area AA1 in the substrate 100, it may be formed to be transparent so as to display a display. In the case of the ineffective area UA in the substrate 100, since display display is unnecessary, it may be formed opaque, but it is not limited thereto.

Alternatively, in the case of the integrated substrate 100, all of them may be formed to be transparent.

The substrate 100 may be rigid or flexible.

In detail, in the case of the first effective area AA1 in the substrate 100, it can be rigid or flexible.

In the case of the second effective area AA2 and the non-effective area UA in the substrate 100, it can be flexible.

Alternatively, when the substrate 100 of the second effective area AA2 and the non-effective area UA are rigid, they can be curved so as to maintain the band shape.

For example, the substrate 100 may be curved with at least some areas having curved surfaces. In detail, the second effective area AA2 and the non-effective area UA of the substrate 100 may have a curved and bent shape. Alternatively, the substrate 100 may have a curved, partially curved, or randomly curved surface and may be curved or bent.

Such a substrate 100 may comprise glass or plastic. In detail, the substrate 100 may include chemically reinforced / semi-tempered glass such as soda lime glass or aluminosilicate glass, or may include polyimide (PI), polyethylene terephthalate (PET) Propylene glycol (PPG) polycarbonate (PC), or the like, or may include sapphire.

Sapphire is a material that can be applied to cover substrate 110 because it has excellent electric characteristics such as dielectric constant and can greatly increase the speed of touch response and can easily realize a space touch such as hovering and has high surface strength. Here, hovering means a technique of recognizing coordinates even at a small distance from the display.

Further, the substrate 100 may include an optically isotropic film. For example, the substrate 100 may include a cyclic olefin copolymer (COC), a cyclic olefin polymer (COP), a polycarbonate (PC), a light polymethyl methacrylate (PMMA), or the like.

On the other hand, a gesture sensor may be disposed on the second effective area AA2 of the substrate 100. [ That is, the gesture of the user can be detected in the second valid area AA2. In detail, when the user wears the band-type sensor and takes a constant gesture, it can be recognized as a gesture sensor disposed in the second effective area AA2.

For example, when the user takes a gesture, a signal is generated in the gesture sensor disposed in the second effective area AA2, and the gesture of the user can be recognized through the signal.

In detail, the gesture sensor can use an electric signal (EMG) generated in the skeletal muscle due to the signal change according to the gesture of the user. However, when the EMG signal is used, the sensor electrode for recognizing the EMG must be exposed to the outside of the wearable sensor.

In the embodiment, in order to compensate for the above disadvantages, a change in capacitance due to the user's gesture can be used as a gesture recognition signal. For example, it is possible to recognize a user's gesture by sensing a change in capacitance occurring between the user and the sensor electrode of the gesture sensor.

In the method of sensing the change in capacitance, the change can be recognized according to the distance between the user and the sensor electrode, and the user's gesture can be detected even if the user is separated from the user by a certain distance. Therefore, even if the band member surrounding the gesture sensor is disposed, the gesture recognition is possible, so that the gesture sensor can be safely protected, and the design restriction can be avoided.

In addition, the capacitance change can be precisely detected according to the distance between the user and the sensor electrode, and the gesture of the user can be accurately recognized.

A touch sensor may be disposed on the first effective area AA1 of the substrate 100. [ In detail, a touch sensor may be disposed on the outer surface of the first effective area AA1. That is, when the touch sensor is disposed on one surface of the substrate 100, the gesture sensor may be disposed on the other surface of the substrate 100. Such a touch sensor can sense the position of a touch of a user's input device (e.g., a finger, etc.).

For example, when an input device such as a finger touches the first effective area AA1, a capacitance change occurs between the input device and the sensing electrode 400 of the touch sensor, Position.

In an embodiment, the touch location may be sensed in the first valid area AA1 where the display is displayed, but is not limited thereto.

That is, on the substrate 100 of the band-shaped sensor according to the embodiment, a gesture sensor for recognizing the user's gesture and a touch sensor for sensing the touch position of the user may be disposed.

In detail, a gesture sensor may be disposed on the inner side of each of the first effective area AA1 and the second effective area AA2 of the substrate 100, and a touch sensor may be disposed on the outer side. In this case, the gesture sensor and the touch sensor can detect the user gesture and the user touch by the change of the capacitance, and the change of the capacitance can be processed by one processor, so that one processor simultaneously detects the user gesture and touch can do. This has the advantage of lowering the unit price of the band-type sensor.

On the other hand, as shown in FIG. 10, the band-type sensor of another embodiment may form only a gesture sensor on a substrate. Such a band-like sensor can be applied to a smart watch (see FIG. 21) or a smart band (see FIG. 22). At this time, since the smart band does not have a display, a touch sensor may not be required (or a separate touch screen may be provided), and such a smart band can be used as an exercise assisting apparatus or a health examination apparatus. Returning to the embodiment, in order to prevent the gesture sensor and the touch sensor from interfering with each other when the gesture sensor and the touch sensor are arranged at the same time, a non-effective area (for example, UA) may be disposed. In detail, the substrate 100 has a first dummy portion 101 disposed in a non-effective region UA between a first effective region AA1 in which a touch sensor is disposed and a second effective region AA2 in which a gesture sensor is disposed . More specifically, the first dummy portion 101 may be disposed between one end of the first effective area AA1 and one end of the second effective area AA2.

In FIG. 5, the first dummy portion 101 is disposed so as to be spaced apart in the horizontal direction from the ineffective area UA and the effective area, but may be disposed so as to be spaced apart in three dimensions.

That is, when the substrate 100 separately includes the first substrate 110 and the second substrate 120, the first dummy portion corresponds to a space where the first substrate 110 and the second substrate 120 are spaced apart from each other .

The second dummy portions 103 and 105 may be disposed at the other end of the first effective area AA1 and / or at the other end of the second effective area AA2.

On the second dummy part (103, 105), the fastening part can be disposed on the wearable device.

Also, the second dummy portions 103 and 105 may overlap with each other, and the diameter of the band-shaped sensor when the band-shaped sensor is formed may be adjusted.

For example, the second dummy portions 103, 105 disposed at the other end of the first effective area AA1 and the second dummy portions 103, 105 disposed at the other end of the second effective area AA2, And both ends of the substrate 100 are connected to the fastening part, so that the substrate 100 can have a strip shape.

And these fastening portions may be configured to be detachable / attachable.

On the other hand, as described above, the substrate 100 of the embodiment may be provided with a gesture sensor.

5 to 7, the gesture sensor according to the embodiment may include a sensor electrode 200 and a sensor wiring electrode 300. [

First, the sensor electrode 200 may be disposed on one side of the substrate 100. In detail, the sensor electrode 200 may be disposed on the second effective area AA2 of the substrate 100. [ In more detail, the sensor electrode 200 may be disposed on the inner surface of the second effective area AA2 of the substrate 100. [ That is, when the substrate 100 is in a strip shape, the sensor electrode 200 is disposed on the inner surface of the second effective area AA2 of the substrate 100 facing the inner surface of the first effective area AA1 of the substrate 100 .

In an embodiment, the sensor electrode 200 may include at least one electrode pattern.

For example, it may be a structure in which a plurality of electrode patterns 201, 202, 203, 204, 205, and 206 are arranged. In detail, the sensor electrodes 200 have a bar pattern, and may be repeatedly arranged left and right by a predetermined distance so as not to contact each other on the same side of the substrate 100. In more detail, the electrode patterns 201, 202, 203, 204, 205, and 206 may be arranged such that the plurality of bar patterns are spaced at regular intervals and arranged in the lateral direction.

In FIGS. 5 to 6, the electrode patterns 201, 202, 203, 204, 205, and 206 are bar-shaped, but the embodiment is not limited thereto. That is, the sensor electrode 200 may have various shapes that can detect whether the band-shaped sensor is in contact with a part of the user's body when the sensor is worn by the user.

The plurality of electrode patterns 201, 202, 203, 204, 205, and 206 arranged in this way are arranged in such a manner that a distance between a user's wearing area and electrode patterns 201, 202, 203, 204, 205, The user can accurately detect the input of the gesture.

The plurality of electrode patterns 201, 202, 203, 204, 205, and 206 of the sensor electrode 200 may be arranged to be symmetrical with respect to the reference line of the second effective area AA2. When the number of electrode patterns 201, 202, 203, 204, 205 and 206 is an even number, the number of left electrode patterns 201, 202 and 203 and the number of right electrode patterns 204, 205, and 206 may be the same, and may be arranged to be symmetrical with respect to the reference line. Alternatively, when the number of the plurality of electrode patterns is an odd number, a plurality of electrode patterns may be arranged so that the electrode patterns are arranged on the reference line, and are symmetrical with respect to the reference lines.

The sensor electrode 200 senses a change in capacitance due to contact with a user's wearing area and a distance, and can detect a user's gesture input.

For example, referring to FIGS. 23 to 28, when a wearer wears a wearable device 1000 including a band-type sensor on the wrist 10, and when the user holds the fist and spreads it, It can be seen that the contact area and distance between the device 1000 and the wearer's wear 10 change.

In detail, when the user holds the fist, the wearable part has a certain shape and changes in the process of bending, so that the contact area and / or contact position of the wearable part 1000 with the wearable device 1000 may vary.

The sensor electrode 200 can detect a change in the contact position and / or contact area as a change in capacitance. In detail, the sensor electrode 200 changes the capacitance generated between the sensor electrode 200 and the wearable area 10 when the wearable area 10 touches or falls on the band of the wearable device in the area corresponding to the gesture sensor Can be detected.

23 to 25, when the user's fist is held, part of the wrist 10 may fall as the muscles of the wrist 10 contract. For example, the third to fifth electrode patterns 203, 204, and 205 may be separated from the wrist. Therefore, the capacitances coupled with the wrist 10 in the third to fifth electrode patterns 203, 204, and 205 can be detected to be small.

On the other hand, referring to Figs. 26 to 28, when the user bends the fist, as the muscles of the wrist 10 are inflated, the gesture sensor and the wrist are all in contact with each other. Therefore, the capacitances coupled with the wrists in the first to sixth electrode patterns 201, 202, 203, 204, 205, and 206 can be largely detected. That is, the sensor electrode 200 can recognize the user's gesture by measuring the contact area and the position with the user as described above.

In the foregoing description, the gesture sensor is capable of recognizing various other gestures, although it has described the operation of gripping the fist with the gesture. For example, at least one of a motion of punching a thumb, a motion of bending the index finger, a motion of avoiding pause, a motion of taking a finger ring, and a motion of holding a finger after the user holds a fist can be recognized as a gesture. Depending on the gesture, the muscles of the wrist may undergo a change in the area where the left or right side protrudes. The gesture sensor can sense the user's gesture through these wrist muscle changes.

Accordingly, when a user wears a band-type sensor and takes a gesture, various gestures that can vary the distance between the wearer's bands and the band can be recognized. This distance variation can be seen through the user's muscle changes.

The user can easily input a signal to the band-shaped sensor through the finger movement, thereby providing an interface optimized for the wearable device.

The sensor electrode 200 can detect a change in capacitance due to contact with a wearer's part and a distance using a self-capacitance method or a mutual-capacitance method.

Since the change in capacitance can be recognized within a certain distance between the wearing area and the sensor electrode 200, the sensor electrode 200 may be disposed within the band of the wearable device.

For example, the sensor electrode 200 can sense a user's gesture through a self-capacitance method. For example, a reference signal can cross the sensor electrode 200 through a uniform resistance design within the sensor electrode 200. That is, a reference signal based on a uniform resistance can be traversed across each of the sensor electrodes 200. In addition, a voltage change occurs due to a change in capacitance formed between the wearing portion and the sensor electrode 200 when the gesture is input, and the contact position, distance, and area can be calculated by calculating the voltage change with time. That is, a time difference occurs in response to a time change depending on a voltage change, and the gesture can be sensed by comparing the modified signal with a reference signal. Such a self-capacitance method has good sensing sensitivity and further allows proximity sensing, so that even if the distance between the wearable part and the sensor electrode 200 is large, the user's gesture can be accurately detected.

The sensor electrode 200 may include a conductive material to allow electricity to flow therethrough. The sensor electrode 200 may be disposed in the band portion when the band-like sensor is disposed in the wearable device, so that it may be opaque.

Therefore, the sensor electrode 200 of the embodiment can be formed to include a metal having high conductivity. For example, the sensor electrode 200 may include at least one metal selected from the group consisting of Cr, Ni, Cu, Al, Ag, Mo, can do.

However, if the gesture sensor is manufactured together with the touch sensor, it may be formed of the same material as the electrode constituting the touch sensor for convenience of the process. Since the electrode forming the touch sensor needs to be transparent, the sensor electrode 200 may include a transparent conductive material.

For example, the sensor electrode 200 may include at least one selected from the group consisting of indium tin oxide, indium zinc oxide, copper oxide, tin oxide, zinc oxide, And may include a metal oxide such as titanium oxide.

Alternatively, the sensor electrode 200 may comprise a nanowire, a photosensitive nanowire film, a carbon nanotube (CNT), a graphene, or a conductive polymer.

8, the sensor electrode 200 may include a mesh shape. In detail, the sensor electrode 200 includes a plurality of sub-electrodes, and the sub-electrodes may be disposed in a mesh shape. In detail, the sensor electrode 200 may include a mesh line LA and a mesh opening OA between the mesh lines LA by a plurality of sub-electrodes crossing each other in a mesh shape.

The line width of the mesh line LA may be about 0.1 mu m to about 10 mu m. The mesh line portion having a line width of the mesh line LA of less than about 0.1 mu m may be impossible in the manufacturing process or may short-circuit the mesh line. If the line width of the mesh line LA is more than about 10 mu m, the electrode pattern may be visually recognized from the outside, . Preferably, the line width of the mesh line LA may be from about 0.5 [mu] m to about 7 [mu] m. More preferably, the line width of the mesh wire may be between about 1 [mu] m and about 3.5 [mu] m.

Further, the mesh openings may be formed in various shapes. For example, the mesh opening OA may have various shapes such as a square, a diamond, a pentagon, a hexagonal polygonal shape, or a circular shape. Further, the mesh opening may be formed in a regular shape or a random shape.

Since the sensor electrode 200 has a mesh shape, the pattern of the sensor electrode 200 can be made invisible on the effective region. That is, even if the sensor electrode 200 is formed of metal, the pattern can be made invisible.

[

Hereinafter, embodiments related to a control method of the wearable device 1000 including the band-shaped sensor 1410 of the above-described embodiments will be described with reference to the accompanying drawings.

30 is a flowchart for explaining a mode change according to whether the wearable device 1000 is worn according to the embodiment.

Referring to FIG. 30, the wearable device 1000 can detect whether or not the user wears the wearable device 1000. (S101, S105)

Specifically, the gesture sensor of the wearable device 1000 can detect whether or not the wearable device 1000 is worn by the user by detecting whether the user and the band 1005 are in contact with each other. For example, the gesture sensor may determine whether or not the wearer wears the wearer's wearer through contact with the band 1005 in which the gesture sensor is disposed, and a change in capacitance occurring between the sensor electrode and the wearer's wearer's touch sensor.

The gesture sensor may transmit the wear detection result to the control unit 1800 of the wearable device 1000 and the control unit 1800 may set the mode of the wearable device 1000 according to whether the wearable device 1000 is worn.

When the control unit 1800 recognizes that the wearable device 1000 is not worn by the gesture sensor, it can control the wearable device 1000 to the first mode. (S103)

For example, in the first mode, the controller 1800 controls the display 1510 to display a black screen. At this time, the black screen is a screen off state, which means that power is not supplied to the screen.

In addition, the touch sensor provided on the display unit 1510 may be supplied with power to enable touch recognition. In this way, power is not supplied to the screen at the time of non-use, and power consumption can be reduced.

In addition, not only the black screen is displayed at the time of non-use, but all components are activated, but at least components such as a control unit 1800, a sensing unit 1400, an input unit 1200, a wireless communication unit 1100, Only the part 1500 and the like can be activated.

If it is determined that the wearable device 1000 is worn by the user, the control unit 1800 of the wearable device 1000 can control the wearable device 1000 in the second mode. (S107)

In the second mode, the control unit 1800 can execute the overall function in the wearable device 1000. [

For example, a predetermined screen may be displayed on the display unit 1510 in the second mode. The predetermined screen may include, for example, an analog clock screen, a digital clock screen, a home screen including a plurality of icons, and simple notification information. Alternatively, the predetermined screen may be a black screen or a peripheral screen.

The simple notification information may include a number, a character, an image, or an icon indicating a text message notification, an SNS notification, an e-mail notification, and the like. The simple notification information does not display detailed information of each notification, for example, when, from whom, and the like. In order to view detailed information of each notification, simple notification information is displayed and then an additional event (gesture) is performed or an authentication process is performed.

In the analog clock screen, only the hands and dials are represented by white tones, and the background is represented by black tones, so that the power can be turned off. In the digital clock screen, only the clock number is expressed in white tones, and the background is expressed in black tones so that the power can be turned off. In this way, the background that occupies most of the analog clock screen and the digital clock screen is not supplied with power, so the power consumption can be reduced.

Therefore, even when the analog clock screen or the digital clock screen of the embodiment is displayed, there is little power consumption, so that the analog clock screen or the digital clock screen can be always displayed as long as the user wears the watch type device on his wrist.

Meanwhile, the wearable device 1000 can detect whether or not the user holds the wearable device 1000 on his / her wrist without wearing it. (S109)

Specifically, when the wearable device 1000 recognizes that the wearable device 1000 is not used and the touch sensor has a touch input, the wearable device 1000 recognizes the wearable device 1000 as a third mode held in the user's hand .

The controller 1800 of the wearable device 1000 can operate the wearable device 1000 according to the third mode if it is determined that the wearable device 1000 is held in the user's hand.

For example, when the wearable device 1000 is held in the hand, a peripheral screen including simple notification information may be displayed on the display portion 1510 of the wearable device 1000. [ Therefore, the user can confirm simple notification information by holding the wearable device 1000 in his or her hand without taking it on the wrist.

The simple notification information may include a number, a character, an image, or an icon indicating a text message notification, an SNS notification, an e-mail notification, and the like. The simple notification information does not display detailed information of each notification, for example, when, from whom, and the like. In order to view detailed information of each notification, simple notification information is displayed and then an additional event (gesture) is performed or an authentication process is performed.

To summarize, the wearable device 1000 determines the first mode (not used), the second mode (wearing the wrist) and the third mode (handedness) by using the band-shaped sensor 1410, .

For example, in the first mode, a black screen or a surrounding screen may be displayed on the display unit 1510).

For example, in the third mode, a screen for the user interface of the display unit 1510 may be displayed.

For example, in the second mode, an idle screen may be displayed on the display unit 1510 instead of a black screen or a surrounding screen. The idle screen may include an analog clock screen, a digital clock screen, and a home screen including a plurality of icons.

31 is a flowchart for explaining a gesture input setting of the wearable device 1000 according to the embodiment.

Hereinafter, with reference to FIGS. 23 to 28 and FIG. 31, a description will be given of a method by which the wearable device 1000 can more precisely detect the user's gesture using the gesture sensor.

As described above, when the wearer wears the wearable device 1000 including the band-shaped sensor 1410 and takes a gesture, a change occurs in the distance to the wearer's part of the band 1005. [ At this time, the gesture sensor can measure the distance from the user's wearing area at each position of the band 1005 by changing the capacitance. Accordingly, when the user takes a constant gesture, the gesture of the user can be detected by recognizing the change pattern of the distance between the band 1005 and the wearing area.

For example, referring to FIGS. 23 to 28, it can be seen that the contact area and distance between the wearable device 1000 and the wearing area of the wearer changes according to the change of the body when the fist is held and opened. In detail, when a user's fist is held, some of the gesture sensor and wrist may fall as some of the muscles of the wrist contract. For example, the third to fifth electrode patterns 203, 204, and 205 may be separated from the wrist. Therefore, the capacitances coupled to the wrists in the third to fifth electrode patterns 203, 204, and 205 can be detected to be small.

On the other hand, when the user fists, as the muscles of the wrist swell, the gesture sensor and the wrist can all come into contact. Therefore, the capacitances coupled with the wrists in the first to sixth electrode patterns 201, 202, 203, 204, 205, and 206 can be largely detected. That is, the sensor electrode 200 can recognize the user's gesture by measuring the contact area and the position with the user as described above.

This change in capacitance can be detected as a profile. In other words, the capacitance that is sensed in the process of holding a fist can vary with a certain tendency.

The control unit 1800 compares the capacitance profile stored in the memory with the capacitance change input from the gesture sensor, and stores the change in the capacitance of the user's gesture (hereinafter referred to as " capacitance change profile " Input can be recognized.

This capacitance profile can be stored in memory by default. However, in the case of being stored as a default, accurate recognition of the gesture may be difficult depending on the shape of the user wearing area or the fastening state of the band 1005.

Accordingly, the wearable device 1000 can more accurately detect the user's gesture input through the gesture input setting process.

First, the control unit 1800 may provide a gesture input setting mode through the display unit 1510. FIG. (S201)

The user can enter the gesture input setting mode through a touch or the like. At this time, in addition to the gesture input setting, the user can also set the overall interface according to the gesture.

In the user gesture input setting mode, the display may require a user ' s constant gesture so that the user can enter a gesture. (S203)

The gesture sensor may transmit the profile of the capacitance according to the gesture input of the user to the control unit 1800. (S205)

The control unit 1800 may store the thus-transmitted capacitance profile in the memory 1700.

Alternatively, to set a capacitance profile according to an accurate gesture, a capacitance profile according to a user's gesture input may be collected again. (S209)

Then, the control unit 1800 sets a profile according to the gesture input through the collected electrostatic capacity profile and the first collected electrostatic capacity profile, and stores the profile in the memory 1700. (S211)

In detail, the control unit 1800 confirms the reacquired electrostatic capacity profile and the degree of coincidence of the first collected electrostatic capacity profile, and when the degree of coincidence is equal to or greater than the preset value, the regenerated electrostatic capacity profile and the initially collected electrostatic capacity profile The capacitance profile according to the gesture input can be set.

For example, the control unit 1800 can set the capacitance profile according to the input of the gesture with the average value of the first collected capacitance profile and the collected collected capacitance profile.

Further, the user can continuously collect profile information according to the gesture input, and the optimized capacitance profile can be updated.

32 is a flowchart for explaining an example of an interface using the band-shaped sensor 1410 in the wearable device 1000 according to the embodiment.

Hereinafter, an example for controlling the wearable device 1000 using the band-shaped sensor 1410 will be described with reference to Fig.

First, the wearable device 1000 can wait for user input in the standby mode. (S301)

For example, the wearable device 1000 may wait in one of the first to third modes described above.

Thereafter, a specific event may occur in the wearable device 1000. (S303)

For example, a signal for a call can be received through the wireless communication unit of the wearable device 1000.

Next, the control unit 1800 can notify the user of the occurrence of the event through at least one configuration of the output unit. (S305)

For example, the display unit 1510 of the output unit may display the event occurrence contents.

In addition, the sound output unit may output an acoustic signal such as a call signal reception sound, a message reception sound, etc. to inform the user of the occurrence of an event. Alternatively, the haptic module of the output may inform the user of the occurrence of an event through various tactile effects, e.g., vibration, that the user may feel.

Also, the light output unit may output a signal for notifying the occurrence of an event using the light of the light source.

Then, the control unit 1800 can receive the gesture input through the band-type sensor 1410. [ (S311)

For example, when the telephone is turned on through the wearable device 1000, the user may grasp the fist, take a bribing gesture, recognize the band-shaped sensor 1410 and transmit it to the control unit 1800.

The control unit 1800 can perform an operation corresponding to the gesture. (S313)

For example, if the fist is set such that the gesture is matched with a signal for receiving a call, the control unit 1800 recognizes the signal as a signal that the user receives a call, and allows the user to make a call through the wireless communication unit Can be controlled.

Alternatively, if the bite gesture is set to match the signal rejecting the call, the control unit 1800 may refuse to receive the call through the wireless communication unit.

Also, the control unit 1800 can receive the touch input through the band-type sensor 1410, and can perform the device control according to the touch input. (S307, S309)

As described above, the band-shaped sensor 1410 can sense not only the touch input but also the re-gesture input by one sensor, thereby providing an interface optimized for the wearable device 1000
