Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

2 is a perspective view showing an example of a watch-type mobile terminal 300 according to another embodiment of the present invention.

2, a watch-type mobile terminal 300 includes a main body 301 having a display unit 351 and a band 302 connected to the main body 301 and configured to be worn on the wrist. In general, the mobile terminal 300 may include features of the mobile terminal 100 of Figures 1A-1C or similar features.

The main body 301 includes a case that forms an appearance. As shown, the case may include a first case 301a and a second case 301b that provide an internal space for accommodating various electronic components. However, the present invention is not limited to this, and one case may be configured to provide the internal space, so that a mobile terminal 300 of a unibody may be realized.

The watch-type mobile terminal 300 is configured to allow wireless communication, and the main body 301 may be provided with an antenna for the wireless communication. On the other hand, the antenna can expand its performance by using a case. For example, a case comprising a conductive material may be configured to electrically connect with the antenna to extend the ground or radiating area.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Figure 3 is a block diagram of a wireless communication module of the electronic device of Figure 2;

As shown, the wireless communication module 310 of the electronic device 300 according to an embodiment of the present invention may include a plurality of modules. For example, the wireless communication module 310 may include first and second wireless communication modules 312, 314.

The first and second wireless communication modules 312 and 314 may be communication modules using different communication methods. For example, the first wireless communication module 312 may be a WiFi communication module and the second wireless communication module 314 may be a Bluetooth communication module.

The control unit 380 of the electronic device 300 can simultaneously activate any one or a plurality of the first and second wireless communication modules 312 and 314. [ For example, when only one of the first wireless communication module 312 and the second wireless communication module 314 is selectively activated or the first wireless communication module 312 is activated, the second wireless communication module 314 ) Can be activated.

Activation may mean that communication with another device through the corresponding communication module is established or can be performed. The control unit of the electronic device 300 according to an embodiment of the present invention can activate the first and second wireless communication modules 312 at an optimal time.

Figures 4 and 5 are flow charts illustrating the operation of the electronic device of Figure 2;

4, the controller of the electronic device 300 according to an embodiment of the present invention performs a step S10 of forming a first communication channel using the first wireless communication module 312 .

The electronic device 300 may be a wearable device. For example, it may be at least one of an electronic device in the form of a wristwatch worn on the user's wrist, an electronic device in the form of a pair of glasses worn on the user's face, and / or a clothes- it means.

The electronic device 300 can exchange data with other electronic devices used by the user. For example, the user can use the electronic device 300, which is an additional wearable device, with the mobile terminal 100 held. The mobile terminal 100 and the electronic device 300 can operate by exchanging data. For example, a user's bio-signal can be sensed by the electronic device 300 closely attached to the user's body and transmitted to the mobile terminal 100, or the content can be acquired through the mobile terminal 100.

The first wireless communication module 312 may be one of the wireless communication modules provided in the electronic device 300. The first wireless communication module 312 may be a Bluetooth communication module. The Bluetooth communication module uses a relatively low current and can exchange data. However, the Bluetooth communication module can transmit data at a relatively low speed.

In the case of the electronic device 300, it may have a smaller battery capacity than the mobile terminal 100. Therefore, effective battery usage can be an important issue.

The controller of the electronic device 300 may form a first communication channel using the first wireless communication module 312, which is a Bluetooth communication module. In the case of using the first communication channel, instantaneous use of the battery may not be large compared with other communication methods.

The control unit of the electronic device 300 may perform step S20 of acquiring information of contents from another device through the first communication channel.

The information of the content may be information about the content to be acquired. For example, the information of the content may include at least one of the size of the content and the kind of the content. For example, the information of the content may be a header of the content. That is, it may be an information area containing information on contents.

And determining whether to form a second communication channel using the second wireless communication module based on the information of the content (S30).

The control unit of the electronic device 300 can determine the characteristics of the content based on the acquired information of the content. For example, it means that it is possible to determine how much the capacity of the content to be downloaded is, and what kind of content to be downloaded.

The control unit of the electronic device 300 may form a second communication channel using the second wireless communication module 314 according to the determined characteristics of the content. The second wireless communication module 314 may be a WiFi communication module.

The WiFi communication module can exchange data at a relatively high speed. That is, it means that data communication can be performed at a higher speed than the Bluetooth communication method. However, if you use WiFi communication mode, battery consumption may increase relatively instantaneously.

The control unit of the electronic device 300 can form the second communication channel when the capacity of the content to be downloaded exceeds a certain range. That is, when the capacity is large, it means that the contents data can be downloaded in the shortest time at a high speed. In the case of using the second communication channel, the instantaneous battery usage can be increased. However, if the total time to use the communication channel is small, the overall battery usage may be smaller than when the first communication channel is used.

The control unit can determine the total battery usage when downloading the content data using the first communication channel and downloading the content data using the second communication channel based on the information of the content. That is, it means that it is possible to determine whether to use the first communication channel having a small instantaneous battery usage but a long usage time or whether to use the second communication channel having a short usage time but a large instantaneous Vetiler usage.

The control unit may perform step S40 of acquiring data of the content using the determined communication channel. In addition, the control unit may perform a process of activating the first communication channel when the data acquisition of the content is completed. For example, if the second communication channel is used, it means that the second communication channel can be deactivated and the first communication channel can be activated again.

FIG. 5 shows an example of the step S30 of determining the formation of the second communication channel. That is, a case where the determination is made based on the capacity of the content data among several factors that can determine the formation of the second communication channel is specifically shown.

The step S30 of determining the formation of the second communication channel may include obtaining the size information of the content to be acquired (S32).

The size of the content is compared with the reference value (S34). If the content size is larger than the reference value, the second communication module 314 is used to form the second communication channel (S36) And maintains the channel (S38).

The reference value may be a content data amount capable of optimizing battery use. For example, if the capacity of the content data is larger than the reference value, it means that it is possible to reduce the total battery usage by fast downloading in a short time.

6 is a diagram showing a content configuration.

As shown, the content C according to an embodiment of the present invention can be composed of a header and a body. The header may be the information of the content (C), and the body may be the data of the content (C).

The header may include information on the content (C). For example, the header may include a location of the content, a kind of the content, a creation date and time of the content, and the like. Further, the header may include information on the size of the content. For example, it may be 'Content-Length' information included in the header.

The control unit can activate or deactivate a specific wireless communication module based on information on the content size included in the header of the content (C).

7 is a signal flow graph illustrating the relationship between another device 100 and an electronic device according to an embodiment of the present invention.

As shown, another device 100 and an electronic device 300 according to an embodiment of the present invention can exchange a constant signal.

The other device 100 may be storing content. (S5)

The electronic device 300 turns on the Bluetooth module (S15) and forms a Bluetooth communication channel with another device (S7).

The electronic device 300 can request the content from another device 100 (S22) and acquire the content information through the service module (S31).

The service module may be a module created on the framework of the electronic device 300. The service module will be described more specifically in the corresponding section.

The electronic device 300 can determine whether the size of the content is larger than the reference value based on the content size information included in the content information (S34).

When the size of the content is larger than the reference value, the Bluetooth module can be turned off and the WiFi module can be turned on (S37)

Using the activated WiFi module, step S39 of forming a WiFi communication channel can be performed. In addition, when the Bluetooth module is turned off, the Bluetooth communication channel can be released.

The step of acquiring the data of the content (S42) may proceed.

The content data can be obtained through a newly formed WiFi module. For example, the header of the content is acquired through the established Bluetooth communication channel, but the body of the content can be acquired through the newly formed WiFi module.

If the size of the content is not larger than the reference value, the content data can be acquired through the previously established Bluetooth communication channel.

It is determined whether WiFi is ON (S52), WiFi is turned OFF, Bluetooth is ON (S54), and Bluetooth communication channel is formed (S56).

Bluetooth communication may have lower current consumption than WiFi communication. Thus, once transmission to large content has been completed, WiFi can be deactivated and Bluetooth enabled to keep the current consumption low.

8 to 10 are diagrams illustrating operations of an electronic device according to various embodiments of the present invention.

As shown in Fig. 8, the electronic device 300 according to the embodiment of the present invention can receive contents from another device 100. Fig. For example, it means that the watch or eyeglass electronic device 300 can receive the content from the user's mobile terminal. This can be easily understood in consideration of the characteristics of the wearable electronic device 300, which is relatively smaller than the user's mobile terminal and has a small storage capacity.

The electronic device 300 may be logically and / or physically formed with an App layer, a Framework layer, and a Kernel layer.

In the App layer, various applications (APPS) may be operating. The application (APP) may request specific content for operation. The specific content may be stored in the mobile terminal 100. [ In such a case, the application APPS may transmit a corresponding request to the kernel layer (S100).

TCP / IP in the kernel layer can redirect a request to a service module on the Framework layer upon receiving a request from an application (APPS) 120. This is because TCP / (S110). ≪ / RTI >

The service module on the Framework layer can create a local server and / or a new socket based on the received request. The service module may transmit the request to the other device 100 via the Kernel layer and start the acquisition of the content from the other device 100. S130 For example, It can start to become.

The service module that has acquired the content can know the total size of the content based on the information of the content. If the size of the content is larger than the reference value, the service module may request the Device Manager of the App layer to control the communication module (S140). Upon receiving the request, the Device Manager may issue an ON and / or OFF command to the BT Manager and / or the WiFi Manager of the Framework Rear (S150)

The service module can forward the socket to the application (APPS) with a request to the Device Manager or if there is a response from the Device Manager. (S160) The application (APPS) receiving the socket can continue to acquire the content.

The content may be obtained through a communication module different from the time when the content is first requested. That is, if the capacity of the content is larger than the reference value, it means that the Bluetooth communication channel can be changed to the WiFi communication channel. Therefore, it is possible to acquire contents quickly with a low battery consumption.

9, the electronic device 300 according to another embodiment of the present invention can perform Bluetooth and / or Wifi activation / deactivation using an Http client module and / or an HttpURL Connenction module in the Framework layer have.

The content request (S100) of the application (APPS) can be transferred (S110) to the TCP / IP module of the kernel layer through the Http Client module. The TCP / IP module can forward the request to another device 100 (S120).

The other device 100 can deliver the content to the TCP / IP module of the electronic device 300 (S130) and the TCP / IP module can deliver the content to the HttpURL Connenction module (S140).

The HttpURL Connection module can determine the capacity of the entire content through the header, which is the information of the transferred content. If the capacity is larger than the reference value, it is possible to request the Device Manager to change the communication module activation (S150).

The Device Manager can forward the command to the BT Manager and / or the WiFi Manager (S160). When the WiFi wireless communication module is activated by command transmission, the content can be acquired through the WiFi communication module thereafter.

10, in the electronic device 300 according to another embodiment of the present invention, the application APPS may directly request a communication module change. That is, the application APPS that receives the content part (S11) in response to the request (S100) to the other device (100) means that it can request the device manager to change the communication module (S120).

11 and 12 are diagrams illustrating a tethering operation of an electronic device according to an embodiment of the present invention.

As shown in these drawings, the electronic device 300 according to an embodiment of the present invention can perform a tethering operation using an optimized communication module.

Fig. 11 shows the relationship of current consumption according to the data size. That is, when the data capacity of the content to be acquired is small, it may be advantageous in terms of current consumption to acquire data using the Bluetooth communication channel. This is because the Bluetooth communication channel can operate in a lower current environment than the WiFi communication channel.

When the data capacity of the content to be acquired exceeds the reference value CS, it may be advantageous in terms of current consumption to acquire data using the WiFi communication channel. This can be understood in view of the fact that the instantaneous current consumption of the WiFi communication channel is large, but the transmission speed is faster than the Bluetooth communication channel. That is, although the instantaneous current consumption is large, the data transmission can be completed within a short time, which means that the overall current consumption can be small.

Fig. 12 (a) shows consumed current according to the size of the content. The content A and the content B may have a relatively large capacity. For example, content A may be about 30 megabytes, and content B may be about 15 megabytes.

It can be seen that when the contents A and B are acquired using the WiFi communication module, the total consumed current is smaller than that when using the Bluetooth communication module. Total dissipation current is calculated by multiplying current by time. Therefore, even if the current is large, the total consumption current may be small if the time is small. Since the transmission speed when using the WiFi communication module is about 7 times faster than when using the Bluetooth communication module, the current required for downloading the entire contents even though the instantaneous consumption current is large is the case where the WiFi communication module is used Can be smaller.

FIG. 12 (b) shows consumed current when a web browser application is used. As shown in the figure, when idle, WiFi consumes 75 mA and Bluetooth consumes 15 mA. Also, when active, WiFi consumes 284 mA and Bluetooth consumes 239 mA. That is, when using any browser application, it may be advantageous to use Bluetooth in both the idle state and the active state. This can be understood more clearly when considering the use characteristics of a web browser application where the relative state is often in the idle state.

13 to 15 are diagrams illustrating screens for selecting a tethering operation according to an embodiment of the present invention.

As shown in these drawings, for the tethering operation according to an embodiment of the present invention, the user and / or the controller can perform a predetermined presetting process.

As shown in Fig. 13 (a), on the display units 151 and 351, a screen for selecting whether to activate the tethering mode can be displayed.

The display units 151 and 351 may be a display unit of the electronic device 300 and / or a display unit of the other device 100. [ For example, in the case of an electronic device 300 in the form of a wristwatch, since a screen is relatively small, a series of processes is performed through the screen of another device 100 connected to the electronic device 300 in the form of a wristwatch Can proceed. However, if the screen of the electronic device 300 has a sufficient size, it goes without saying that a series of processes can be performed through the screen of the electronic device 300. Hereinafter, they are the same unless otherwise described.

As shown in FIG. 13 (b), the tethering mode may include a case where only WiFi is used, and a case where WiFi and Bluetooth are mutually switched according to a certain condition when only Bluetooth is used. The user and / or the control unit can select any one of them.

As shown in Fig. 14 (a), when the case where WiFi and Bluetooth are switched to each other is selected, the selection for the reference can proceed. For example, it can be automatically switched according to the judgment of the control section, switched according to the size of the content, or switched depending on the application requesting the content.

As shown in (b) of FIG. 14, if the case of switching the tethering according to the size of the contents is selected, the user can select the reference size to be switched to tethering. For example, it means that the size of the selection bar SB can be selected by selecting the selection bar SB with a finger or the like.

As shown in (a) of FIG. 15, if the case where the tethering is switched according to the application requesting the content is selected, a process of selecting an application can be performed. For example, it means that the application using the content is listed, and the user can directly select a specific application. In the case of creating a service module in the Framewoke layer according to an embodiment of the present invention, a specific application to perform tethering can be selected. That is, it means that the service module can deliver a newly created socket to a predetermined specific application.

16 and 17 are diagrams showing the timing of tethering of an electronic device according to an embodiment of the present invention.

As shown in these drawings, the electronic device 300 according to an embodiment of the present invention can perform tethering according to a certain criterion.

There may be a reference value CS for tethering. For example, the reference value CS may be determined by the user's selection and / or the control signal of the control unit.

When the traffic to which the data is transmitted increases according to the request for the content and exceeds the reference value CS, it can be switched to WiFi. For example, it means that Bluetooth can be switched to WiFi at time t1.

If the traffic does not reach the reference value CS, it can be switched back to Bluetooth. For example, it means that WiFi can be switched to Bluetooth at time t2.

When the traffic does not exist for a certain period of time, the communication module can be deactivated. For example, it means that the consumption of the battery can be minimized by deactivating the communication module from the time t4 to the time t5.

The control unit can deactivate the communication module at a time point t4 when a predetermined time has elapsed from the time t3 when the traffic becomes zero. That is, if the possibility of reuse is low, it means that the communication module can be deactivated. The communication module can be activated again at the time when traffic again occurs.

As shown in Fig. 17A, the time point at which WiFi is switched to Bluetooth may be different from the point in time when it does not reach the reference value CS. For example, the traffic may be below the reference value CS at time t3. However, the point of transition from WiFi to Bluetooth may be the time point t4 after the buffer time. The buffer time can serve to prevent frequent tethering transitions.

As shown in FIG. 17 (b), the switching between WiFi and Bluetooth may be determined by factors other than traffic. For example, ON / OFF of the display unit may affect the switching.

At the time t1, the display unit can be turned off. OFF of the display unit may include a case where the display unit is dimmed. That is, this means that the backlight of the display part is turned off and / or the display part is completely turned off because the operation is not inputted for a predetermined time or more. Such a situation may occur because the user no longer operates the electronic device and / or other devices. Therefore, if there is no additional operation by the user, the content may be acquired at a relatively low speed.

The control unit can switch to Bluetooth after a predetermined buffer time at the time t1 when the switch is turned off. Therefore, frequent switching can be prevented in advance.

18 is a diagram showing a tethering operation of an electronic device according to an embodiment of the present invention.

As shown, the electronic device 300 according to an embodiment of the present invention can perform tethering based on various conditions.

As shown in FIG. 18A, the electronic device 300 performs tethering when the other device 300 is within a certain distance R, and stops tethering when the device 300 is outside the predetermined distance R have. Through this operation, it is possible to prevent a case where a large amount of current is used for tethering with another device 300 which is far from the device.

As shown in Fig. 18 (b), the electronic device 300 in the form of a wristwatch can perform tethering depending on whether the user wears it. For example, it means that tethering can be activated if the user wears it, and tethering can be disabled if not worn.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative.
