Description

wearable device {WEARABLE DEVICE}

Embodiments relate to wearable devices.

In various electronic products, a touch window for inputting an image displayed on a display device by a method of contacting an input device such as a finger or a stylus is applied.

Recently, a touch window has been applied not only to a device that a user directly holds and uses, such as a terminal, but also a wearable device such as a smart watch or smart glasses, which is easily carried by a user wearing it directly on the body.

In the case of such a wearable device, it is easy to carry, and thus, it is in the spotlight as a next-generation device that can replace a general mobile phone in the future.

However, a general touch panel is currently applied to sensors for a user interface applied to a wearable device.

However, while the wearable device is worn on a part of the user's body, such as a user's body, neck, head, and wrist, when a touch panel for sensing a touch position is applied as it is, the advantages of wearables may be diminished.

Accordingly, sensors capable of providing an interface suitable for a user are required for a wearable device, out of the structure of an existing touch window that simply detects a touch position.

An embodiment is to provide a wearable device capable of providing a new interface based on a gesture input.

A wearable device according to an embodiment includes a memory for storing data for executing a function of the wearable device having a band shape; a sensing unit sensing a user gesture input as a change in capacitance; and a control unit that processes the data according to the sensed change in capacitance to execute a function of the wearable device.

Since the sensing unit of the wearable device of the embodiment may recognize the user's gesture input as a change in capacitance, a user interface optimized for the wearable device may be enabled based on the gesture recognition.

Furthermore, the sensing unit of the wearable device according to the embodiment may be a hybrid sensor capable of recognizing a user's touch.

Specifically, the sensing unit of the wearable device includes a gesture sensor, and the gesture sensor may precisely detect a change according to a user's movement.

Such a gesture sensor includes a sensor electrode, and by detecting a change in capacitance that occurs between the sensor electrode and the body when the user touches or falls off the wearable sensor in the area corresponding to the gesture sensor, the user's gesture can be accurately detected. there is.

In addition, according to an embodiment, the wearable device may include a gesture sensor for recognizing a user gesture and a touch sensor for detecting a user's touch location at the same time, and the gesture sensor and the touch sensor are capacitive to the user's gesture and the user's touch. change can be detected. That is, since the band-type sensor can measure a touch input and a gesture input as a change in capacitance, and one processor can process this change in capacitance, a single processor simultaneously detects a user gesture and a touch can do.

In an embodiment, the wearable device may be operated based on a user gesture as well as a touch, thereby further improving user convenience.

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

Referring to FIG. 1 , the band-type sensor may have a band shape. In addition, both ends of the band-type sensor may be in contact with or partially overlapped to form a band.

Also, in the band-type sensor, effective areas AA1 and AA2 and non-effective areas UA may be defined. In addition, the effective area may include a first effective area AA1 and a second effective 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. In this case, the ineffective area UA may be disposed between the first effective area AA1 and the second effective area AA2 to form a band shape.

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

In addition, an area other than the first effective area AA1 and the second effective area AA2 may be defined as the non-effective area UA.

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

For example, the touch sensor may be disposed toward the outer surface OS side of the first effective area AA1. In detail, the band-type sensor may detect a touch input to the outer surface OS of the first effective area AA1 that the user can see when both ends of the band-type sensor are in contact with or overlapped to form a band.

2 to 10 , the band-type 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-type sensor. That is, the substrate 100 may have a band shape. Accordingly, the substrate 100 is disposed in the first effective area AA1 , the second effective area AA2 , and the non-effective area UA disposed between both sides of the first effective area AA1 and the second effective area AA2 . can be placed.

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

The substrate 100 includes 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 a single substrate 100 . In addition, the substrate 100 may reduce the unit cost by omitting a portion of the unnecessary ineffective area UA. Alternatively, as shown in FIG. 4 , the substrate 100 according to another embodiment may include at least one substrate 100 . For example, the substrate 100 may include the second substrate 120 disposed in the second effective area AA2 . Also, the substrate 100 may include the first substrate 110 disposed in the 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 disposed to be spaced apart.

When the substrate 100 is the first substrate 110 or the second substrate 120 , the band-type sensor may be disposed in only a partial region of the wearable device (eg, FIG. 18 ). For example, when the substrate 100 is the first substrate 110 , the touch sensor may be disposed in an area corresponding to the display unit of 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.

In this case, the band-type sensor may include only a 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, the first effective area AA1 and the other area of the substrate 100 may be formed of different materials.

In addition, the substrate 100 may be formed to be transparent. In the case of the first effective area AA1 of the substrate 100 , in order to display a display, it may be formed to be transparent. In the case of the non-effective area UA of the substrate 100 , since display display is unnecessary, it may be formed opaque, but is not limited thereto.

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

In addition, the substrate 100 may be rigid or flexible.

In detail, the first effective area AA1 of the substrate 100 may be rigid or flexible.

The second effective area AA2 and the non-effective area UA of the substrate 100 may be flexible.

Alternatively, when the substrate 100 of the second effective area AA2 and the non-effective area UA is rigid, it may be curved to maintain a band shape.

For example, at least a portion of the substrate 100 may be curved while having a curved surface. In detail, the second effective area AA2 and the ineffective area UA of the substrate 100 may have a curved surface and may have a curved band shape. Alternatively, the substrate 100 may be bent or curved while having a partially curved surface, or may have a surface including a random curvature and be curved or bent.

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

Sapphire is a material that can be applied to the cover substrate 110 because of its excellent electrical properties such as dielectric constant, which can dramatically increase the touch response speed, can easily implement spatial touch such as hovering, and has high surface strength. Here, hovering refers to a technique for recognizing coordinates even at a distance slightly away from the display.

In addition, the substrate 100 may include a photoisotropic film. For example, the substrate 100 may include Cyclic Olefin Copolymer (COC), Cyclic Olefin Polymer (COP), photoisotropic polycarbonate (PC), or photoisotropic polymethyl methacrylate (PMMA).

Meanwhile, a gesture sensor may be disposed on the second effective area AA2 of the substrate 100 . That is, the user's gesture may be detected in the second effective area AA2 . In detail, when a user wears a band-type sensor and takes a certain gesture, it may be recognized as a gesture sensor disposed in the second effective area AA2 .

For example, when the user makes a gesture, a signal may be generated in the gesture sensor disposed in the second effective area AA2, and the user's gesture may be recognized through the signal.

In detail, the gesture sensor may use an electrical signal (EMG) generated in the skeletal muscle as a signal change according to the user's gesture. However, when using the EMG signal, there is a disadvantage that 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 this disadvantage, a change in capacitance according to a user's gesture may be used as a gesture recognition signal. For example, the user's gesture may be recognized by detecting a change in capacitance generated between the user and the sensor electrode of the gesture sensor.

This method of sensing the change in capacitance can recognize a change according to the distance between the user and the sensor electrode, so that the user's gesture can be detected even if the user is separated by a predetermined distance or more. Therefore, even when a band member surrounding the gesture sensor is disposed, gesture recognition is possible, the gesture sensor can be safely protected, and design restrictions can be avoided.

In addition, it is possible to precisely detect a change in capacitance according to the distance between the user and the sensor electrode, so that the user's gesture can also be accurately recognized.

In addition, 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 may detect a position of a touch of a user's input device (eg, a finger, etc.).

For example, when an input device such as a finger is in contact with the first effective area AA1 , a change in capacitance occurs between the input device and the sensing electrode 400 of the touch sensor, and a portion in which the change occurs is touched. position can be detected.

In an embodiment, the touch position may be sensed in the first effective area AA1 where the display is displayed, but the present invention is not limited thereto.

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

In detail, a gesture sensor may be disposed inside each or one area of the first effective area AA1 or the second effective area AA2 of the substrate 100 , and a touch sensor may be disposed outside the substrate 100 . In this case, since the gesture sensor and the touch sensor can detect the user gesture and the user's touch as a change in capacitance, and the change in capacitance can be processed by one processor, a single processor simultaneously detects the user's gesture and touch can do. Through this, there is an advantage that the unit cost of the band-type sensor can be lowered.

Meanwhile, as shown in FIG. 10 , in the band-type sensor of another embodiment, only the gesture sensor may be formed on the substrate. In addition, such a band-type sensor may be applied to a smart watch (see FIG. 21 ) or a smart band (see FIG. 22 ). In this case, 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 may be used as an exercise assistance device or a health diagnosis device. Returning to the embodiment, when the gesture sensor and the touch sensor are disposed at the same time, in order to prevent the gesture sensor and the touch sensor from interfering, an invalid area ( ) between the first effective area AA1 and the second effective area AA2 UA) can be deployed. In detail, in the substrate 100 , the first dummy part 101 is disposed in the non-effective area UA between the first effective area AA1 in which the touch sensor is disposed and the second effective area AA2 in which the gesture sensor is disposed. can be In more detail, the first dummy part 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 part 101 is disposed to be spaced apart from the effective area UA in the horizontal direction, but may be disposed to be spaced apart from each other in three dimensions.

That is, when the substrate 100 includes the first substrate 110 and the second substrate 120 separately, the first dummy portion corresponds to a space in which the first substrate 110 and the second substrate 120 are spaced apart. can

In addition, the second dummy parts 103 and 105 may be disposed at the other end of the first effective area AA1 and/or the other end of the second effective area AA2 .

In addition, a fastening part may be disposed on the second dummy part 103 and 105 in the wearable device.

In addition, the second dummy parts 103 and 105 may overlap each other, and through this, the diameter of the band-shaped sensor when the band-shaped sensor is adjusted can be adjusted.

For example, the second dummy parts 103 and 105 disposed at the other end of the first effective area AA1 and the second dummy parts 103 and 105 disposed at the other end of the second effective area AA2 are respectively fastened to each other. By disposing an additional portion and connecting both ends of the substrate 100 with the fastening portion, the substrate 100 may have a band shape.

And this fastening part may be configured to be detachable/attached.

Meanwhile, as described above, a gesture sensor may be disposed on the substrate 100 of the embodiment.

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

First, the sensor electrode 200 may be disposed on one surface 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 has 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 . can be

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

For example, the plurality of electrode patterns 201 , 202 , 203 , 204 , 205 , and 206 may be arranged in a structure. In detail, the sensor electrodes 200 may have a bar pattern, and may be spaced apart from each other by a predetermined interval so as not to contact each other on the same surface of the substrate 100 , and may be repeatedly arranged left and right. In more detail, the electrode patterns 201 , 202 , 203 , 204 , 205 , and 206 are vertically elongated bar patterns, and the plurality of bar patterns may be arranged so as to be horizontally spaced apart from each other at equal intervals.

5 to 6 , the electrode patterns 201 , 202 , 203 , 204 , 205 , and 206 are illustrated as having a bar shape, but the embodiment is not limited thereto. That is, when the band-type sensor is worn by the user, the sensor electrode 200 may have various shapes capable of detecting whether it is in contact with a part of the user's body.

The plurality of electrode patterns 201 , 202 , 203 , 204 , 205 and 206 arranged in this way change the distance between the user's wearing part and the electrode patterns 201 , 202 , 203 , 204 , 205 , 206 when a predetermined gesture is input. By measuring the change in capacitance according to the , it is possible to accurately detect the user's gesture input.

In addition, 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 . In detail, when the number of the plurality of electrode patterns 201, 202, 203, 204, 205, and 206 is even, the number of the left electrode patterns 201, 202, 203 and the right electrode pattern 204, The number of 205 and 206 may be the same, and may be arranged so as to be left and right symmetrical in the reference line. Alternatively, when the number of the plurality of electrode patterns is an odd number, the electrode patterns may be disposed on the reference line, and the plurality of electrode patterns may be disposed to be symmetrical with respect to the reference line.

The sensor electrode 200 may detect a user's gesture input by detecting a change in capacitance according to the degree of contact and distance from the user's wearing part.

For example, referring to FIGS. 23 to 28 , when the user wears the wearable device 1000 including the band-type sensor on the wrist 10 , and opens and closes the fist, the wearable device according to the change of the body It can be seen that the contact area and distance between the device 1000 and the wearing part 10 of the user change.

In more detail, in the process of clenching and opening a fist, the worn portion has a certain shape and is changed, and accordingly, an area and/or contact position between the worn portion 10 and the wearable device 1000 may change.

The sensor electrode 200 may detect a change in a contact position and/or a contact area as a change in capacitance. In detail, the sensor electrode 200 detects a change in capacitance that occurs between the sensor electrode 200 and the worn portion 10 when the worn portion 10 comes into contact with or falls off the band of the wearable device in the region corresponding to the gesture sensor. can detect

23 to 25 , when the user's fist is clenched, as some muscles of the wrist 10 contract, the gesture sensor and a part of the wrist 10 may be separated. For example, the third to fifth electrode patterns 203 , 204 , and 205 may move away from the wrist. Accordingly, a small capacitance coupled to the wrist 10 in the third to fifth electrode patterns 203 , 204 , and 205 may be sensed.

On the other hand, referring to FIGS. 26 to 28 , when the user makes a fist, as the muscle of the wrist 10 expands, the gesture sensor and the wrist may all contact each other. Therefore, the capacitance coupled to the wrist in the first to sixth electrode patterns 201 , 202 , 203 , 204 , 205 and 206 may be significantly sensed. That is, the sensor electrode 200 may recognize the user's gesture by measuring the contact area and position with the user as described above.

In the above description, the gesture of clenching and opening a fist has been described, but the gesture sensor may recognize various other gestures. For example, after the user makes a fist, at least one of an action to open a thumb, an action to open the index finger, an action to open the middle finger, an action to open the ring finger, and an action to open the small finger may be recognized as a gesture. And according to this gesture, the muscle of the wrist may change in the part where the left or right side protrudes. The gesture sensor may detect the user's gesture through these changes in the wrist muscle.

Accordingly, when the user wears the band-type sensor and makes a gesture, various gestures in which the distance between the wearing part and the band may change may be recognized. This distance change may appear through the user's muscle change.

A user can easily input a signal to the band-type sensor through finger movement, thereby providing an interface optimized for wearable devices.

The sensor electrode 200 may detect a change in capacitance according to the degree of contact and distance from the user's wearing part using a self-capacitance method and/or a mutual-capacitance method.

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

For example, the sensor electrode 200 may detect a user's gesture through a self-capacitance method. For example, a reference signal may cross the sensor electrode 200 through a uniform resistance design in the sensor electrode 200 . That is, a reference signal due to a uniform resistance may cross each of the sensor electrodes 200 . In addition, when a gesture is input, a voltage change occurs due to a change in capacitance formed between the wearing part and the sensor electrode 200 , and here, by calculating the voltage change over time, the contact position, distance, and area can be calculated. That is, a time difference occurs with respect to a time response according to a voltage change, and the gesture can be detected by comparing a signal transformed by this with a reference signal. Since the self-capacitance method has good sensing sensitivity and also enables proximity sensing, a user's gesture can be accurately detected even if the distance between the wearing part and the sensor electrode 200 is long.

The sensor electrode 200 may include a conductive material to allow electricity to flow. Since the sensor electrode 200 may be disposed on the band portion when the band-type sensor is disposed on the wearable device, it may be opaque.

Accordingly, the sensor electrode 200 of the embodiment may be formed to include a metal having high conductivity. For example, the sensor electrode 200 includes at least one metal of chromium (Cr), nickel (Ni), copper (Cu), aluminum (Al), silver (Ag), molybdenum (Mo), and alloys thereof. can do.

However, when 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 constituting 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 indium tin oxide, indium zinc oxide, copper oxide, tin oxide, zinc oxide, or titanium. It may include a metal oxide such as titanium oxide.

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

Also, as shown in FIG. 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 while crossing each other 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 μm to about 10 μm. The mesh line portion having a line width of less than about 0.1 μm of the mesh wire LA may be impossible in the manufacturing process, or a short circuit of the mesh line may occur, and when it exceeds about 10 μm, the electrode pattern may be visually recognized from the outside and visibility may be reduced. . Preferably, the line width of the mesh line LA may be about 0.5 μm to about 7 μm. More preferably, the line width of the mesh line may be about 1 μm to about 3.5 μm.

In addition, the mesh opening may be formed in various shapes. For example, the mesh opening OA may have various shapes, such as a rectangular shape, a diamond shape, a pentagonal shape, a hexagonal polygonal shape, or a circular shape. In addition, 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 area. That is, even if the sensor electrode 200 is formed of metal, the pattern may be invisible. In addition, resistance can be lowered even when the sensor electrode 200 is applied to a large-sized band-type sensor.

The sensor wiring electrodes 300 electrically connecting the sensor electrodes 200 may be disposed in the ineffective area UA.

A plurality of sensor wiring electrodes 300 may be provided. That is, the sensor wire electrodes 300 may include a first sensor wire electrode 310 connected to one end of the sensor electrode 200 and a second sensor wire electrode 320 connected to the other end of the sensor electrode 200 . there is. Accordingly, the first sensor wiring electrode 310 may be drawn out to the top of the substrate 100 . In addition, the second sensor wiring electrode 320 may be drawn out to the lower end of the substrate 100 .

For example, the first sensor wiring electrode 310 may extend to the first dummy part 101 after being drawn out from the upper end of the substrate 100 . In addition, the printed circuit board 600 may be disposed on the first dummy part 101 adjacent to the first effective area AA1 . In addition, the first sensor wiring electrode 310 may be connected to the printed circuit board 600 .

Alternatively, the printed circuit board 600 may be disposed in the first effective area AA1 , and the first sensor wiring electrode 310 may be connected to the printed circuit board 600 .

Similarly, after the second sensor wiring electrode 320 is drawn out to the lower end of the substrate 100 , it may extend to the first dummy part 101 . In addition, the printed circuit board 600 may be disposed on the first dummy part 101 adjacent to the first effective area AA1 , and the second sensor wiring electrode 320 may be connected to the printed circuit board 600 .

Alternatively, the printed circuit board 600 may be disposed in the first effective area AA1 , and the second sensor wiring electrode 320 may be connected to the printed circuit board 600 .

In an embodiment, as shown in FIG. 7 , the touch sensor and the gesture sensor may be disposed on different surfaces of the substrate 100 .

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

30 is a flowchart illustrating a mode change according to whether the wearable device 1000 is worn or not, according to an embodiment.

Referring to FIG. 30 , the wearable device 1000 may detect whether the user wears the wearable device 1000 . (S101, S105)

Specifically, the gesture sensor of the wearable device 1000 may detect whether the user and the band 1005 are in contact, and may determine whether the wearable device 1000 is worn by the user. For example, the gesture sensor may determine whether to wear the gesture sensor through a change in capacitance generated between a sensor electrode of the gesture sensor and the worn portion when the user's wearing part contacts the band 1005 on which the gesture sensor is disposed.

The gesture sensor may transmit a wearable detection result to the controller 1800 of the wearable device 1000 , and the controller 1800 may set a mode of the wearable device 1000 according to whether the wearable device is worn.

The controller 1800 may control the wearable device 1000 to the first mode when recognizing that it is not worn by the gesture sensor. (S103)

For example, in the first mode, the controller 1800 may control the display unit 1510 to display a black screen. In this case, the black screen is a screen off state and may mean when power is not supplied to the screen.

Separately, power may be supplied to the touch sensor provided on the display unit 1510 to enable touch recognition. As such, power consumption may be reduced because power is not supplied to the screen when not worn.

In addition, when not worn, not only a black screen is displayed, but not all components are activated, but a minimum of components, for example, the control unit 1800, the sensing unit 1400, the input unit 1200, the wireless communication unit 1100, and the output Only part 1500 and the like can be activated.

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

In the second mode, the controller 1800 may execute an overall function in the wearable device 1000 .

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

The simple notification information may include numbers, characters, images, or icons indicating text message notifications, SNS notifications, email notifications, and the like. In the simple notification information, detailed information of each notification, for example, when, from whom, and what content is not displayed. In order to view detailed information of each notification, after simple notification information is displayed, an additional event (gesture) must be performed or an authentication process must be performed.

In the analog watch screen, only hands and dials are expressed in a white gradation, and the background is expressed in a black gradation, so that the power may be turned off. On the digital watch screen, only the clock number is expressed in a white gradation, and the background is expressed in a black gradation, and the power may be turned off. As such, power consumption may be reduced because power is not supplied to the background occupying most of the analog watch screen or digital watch screen.

Therefore, even if the analog watch screen or the digital watch screen of the embodiment is displayed, power consumption is hardly consumed, so that the analog watch screen or the digital watch screen is always displayed without turning off as long as the user wears the watch type device on the wrist.

Meanwhile, the wearable device 1000 may detect whether the user holds the wearable device 1000 on the wrist without wearing it. (S109)

Specifically, if the gesture sensor of the wearable device 1000 recognizes that it is not worn and there is a touch input to the touch sensor at the same time, the control unit 1800 may recognize the wearable device 1000 as the third mode held in the user's hand. .

When it is determined that the wearable device 1000 is held in the user's hand, the controller 1800 of the wearable device 1000 may operate the wearable device 1000 according to the third mode.

For example, when the wearable device 1000 is held in a hand, a surrounding screen including simple notification information may be displayed on the display unit 1510 of the wearable device 1000 . Accordingly, the user can check simple notification information by holding the wearable device 1000 in the hand without wearing it on the wrist.

The simple notification information may include numbers, characters, images, or icons indicating text message notifications, SNS notifications, email notifications, and the like. In the simple notification information, detailed information of each notification, for example, when, from whom, and what content is not displayed. In order to view detailed information of each notification, after simple notification information is displayed, an additional event (gesture) must be performed or an authentication process must be performed.

In summary, the wearable device 1000 determines the first mode (not worn), the second mode (worn on the wrist), and the third mode (holds the hand) using the band-type sensor 1410 , and functions in the determined mode. can run

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, a standby screen may be displayed on the display unit 1510 instead of a black screen or a surrounding screen. The standby screen may include an analog watch screen, a digital watch screen, and a home screen including a plurality of icons.

31 is a flowchart illustrating a gesture input setting of the wearable device 1000 according to an exemplary embodiment.

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

As described above, when a user wears the wearable device 1000 including the band-type sensor 1410 and makes a gesture, a change occurs in the distance to the wearable part of the user on the band 1005 . In this case, the gesture sensor may measure the distance from the user's wearing part at each position of the band 1005 as a change in capacitance. Accordingly, when the user takes a certain gesture, the user's gesture can be detected by recognizing a change pattern of the distance between the band 1005 and the wearing part.

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 wearable part of the user change according to changes in the body when the fist is clenched and opened. In detail, when the user's fist is clenched, as some muscles of the wrist contract, the gesture sensor and a part of the wrist may be separated. For example, the third to fifth electrode patterns 203 , 204 , and 205 may move away from the wrist. Accordingly, a small capacitance coupled to the wrist in the third to fifth electrode patterns 203 , 204 , and 205 may be sensed.

On the other hand, when the user makes a fist, as the muscles of the wrist expand, the gesture sensor and the wrist may all come into contact. Therefore, the capacitance coupled to the wrist in the first to sixth electrode patterns 201 , 202 , 203 , 204 , 205 and 206 may be significantly sensed. That is, the sensor electrode 200 may recognize the user's gesture by measuring the contact area and position with the user as described above.

This change in capacitance can be detected as a profile. In other words, the capacitance sensed in the process of clenching and opening a fist has a certain tendency and can be changed.

The process of changing the capacitance according to the predetermined gesture (hereinafter, referred to as “capacitance profile”) is stored in the memory, and the controller 1800 compares the capacitance profile stored in the memory with the change in capacitance input from the gesture sensor to perform the user's gesture input can be recognized.

This capacitive profile may be stored by default in the memory. However, when stored as a default, it may be difficult to accurately recognize the gesture depending on the shape of the user's wearing part or the tightening state of the band 1005 .

Accordingly, the wearable device 1000 may 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 . (S201)

The user may enter the gesture input setting mode through a touch or the like, and in this case, the overall interface according to the gesture may be set together with the gesture input setting.

In the user gesture input setting mode, the display may request a user's specific gesture, and accordingly, the user may input the gesture. (S203)

The gesture sensor may transmit a capacitance profile according to the user's gesture input to the controller 1800 . (S205)

The controller 1800 may store the transmitted capacitance profile in the memory 1700 .

Alternatively, in order to set the capacitance profile according to the correct gesture, the capacitance profile according to the user's gesture input may be collected again. (S209)

Thereafter, the controller 1800 may set a profile according to the gesture input through the re-collected capacitive profile and the first-collected capacitive profile and store it in the memory 1700 . (S211)

In detail, the control unit 1800 checks the degree of matching between the recollected capacitance profile and the initially collected capacitance profile, and when the degree of matching is greater than or equal to a preset value, through the recollected capacitance profile and the initially collected capacitance profile Capacitance profile according to gesture input can be set.

For example, the controller 1800 may set the capacitance profile according to the gesture input as an average value of the initially collected capacitance profile and the re-collected capacitance profile.

In addition, by continuously collecting profile information according to the user's gesture input thereafter, the capacitance profile optimized for the user may be updated.

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

Hereinafter, an example for controlling the wearable device 1000 using the band-type sensor 1410 will be described with reference to FIG. 32 .

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

For example, the wearable device 1000 may stand by in one of the aforementioned first to third modes.

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

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

Next, the controller 1800 may notify the user that the event has occurred through at least one configuration of the output unit. (S305)

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

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

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

Thereafter, the controller 1800 may receive a gesture input through the band-type sensor 1410 . (S311)

For example, when a call is received through the wearable device 1000 , the user may make a clenched fist and blood gesture, recognize the band-type sensor 1410 and transmit it to the controller 1800 .

In addition, the controller 1800 may execute an operation corresponding to such a gesture. (S313)

For example, if the clenched fist and blood gesture is set to match the signal for receiving a call, the controller 1800 recognizes this as a signal that the user receives a call, so that the user can make a call with the other party through the wireless communication unit. can be controlled

Alternatively, if the clenched fist gesture is set to match the call rejection signal, the controller 1800 may reject the call reception through the wireless communication unit.

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

As described above, the band-type sensor 1410 may sense not only a touch input but also a gesture input with one sensor, thereby providing an interface optimized for the wearable device 1000 .
