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.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. 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). Whether to perform different controls or to perform the same control according to the type of the touch object can be determined according to the operating state of the electronic device 100 or an application program being executed.

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.

When the battery 191 is detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

The electronic device 100 may be provided with an accessory that protects the appearance or supports or expands the function of the electronic device 100. One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the electronic device 100.

[ Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

However, the electronic device 100 according to the present invention may include various types of display devices capable of transmitting and receiving contents as well as the form of a mobile terminal shown in the figure. Hereinafter, for convenience of explanation, the control method of the present invention will be described with the electronic apparatus of the mobile terminal type.

3 is a flowchart illustrating a method of controlling an electronic device according to an embodiment of the present invention.

The memory 170 stores the content (S510). There are no restrictions on the content of the content, such as documents, images, movies, and music files. For example, if an image is acquired by the camera 121, the acquired image becomes the content. The content may be temporarily stored in the memory 170.

The control unit controls the wireless communication unit 110 to establish wireless connection with a plurality of external devices (S520). For example, the control unit wirelessly connects to an external device located within a predetermined distance using a communication method such as WiFi, Bluetooth (BT), or the like. For example, the wireless communication unit can perform data transmission from one device to a plurality of devices by a WFDS function.

When the controller is wirelessly connected to a plurality of external devices, the controller classifies the plurality of external devices into a sub-device and a sink device (S530). The control unit measures the number of the plurality of external devices wirelessly and designates a plurality of sub-devices to forward data through a communication method used for wireless connection, and designates a sink device that receives data from each sub-device .

Here, the sub-device corresponds to an external device that receives content from the electronic device and transmits the content to a plurality of sink devices. The sub-device among the plurality of external devices can be designated as two or more devices. Accordingly, the control unit of the electronic device only transmits the content to be transmitted to the plurality of sub-devices, and the sub-device selectively transmits the entire contents to the sink device.

The control unit may perform a step of analyzing information on a wireless connection state and a distance between the sub-device and the sink device to designate the sub-device and the sink device. For example, the sink device wirelessly connected to each of the sub devices may correspond to a case where the sink devices are disposed at a distance from other sub devices. That is, one sub-device and a plurality of sink devices that wirelessly communicate with each other constitute one group. The control unit may form a plurality of groups including the sub-device and the plurality of sink devices.

The control unit transmits the content and the information of the sink device to the sub-device (S540). The control unit transmits all contents to be transmitted to a plurality of external devices. The information of the sink device may correspond to information of a sink device forming a group with the sub device. For example, the information of the sink device may include unique information for distinguishing the sink device from other external devices, information about data to be received by the sink device, and the like.

That is, the control unit of the electronic device according to the present invention selects a sub-device among a plurality of devices connected when a content is transmitted to a plurality of external devices, and controls the sub-device to transmit the content. Accordingly, since a content is transmitted only to a sub-device among a plurality of external devices, a large amount of contents can be transmitted at a time. Therefore, it is possible to transmit the contents without using a separate communication service.

Hereinafter, the control step of transmitting content will be described in more detail with reference to FIGS. 4A to 4E. FIG. 4A is a flowchart illustrating a method of controlling a transmission system for transmitting the content to a sink device according to an embodiment of the present invention. FIG. 4B is a conceptual diagram of a content transmission system for explaining the control method of FIG. 4A according to an embodiment, and FIG. 4C is a conceptual diagram for explaining a control step of switching an external device to a standby state based on a standby request signal. FIG. 4D is a conceptual diagram for explaining a control step of transmitting content transmission information and information related to a sink device from an electronic device to a sub device. FIG. 4E illustrates a control step of transmitting content based on content request information of the sink device FIG.

4A and 4B, the electronic device 100 is wirelessly connected to a plurality of external devices (S530). For example, the electronic device 100 is wirelessly connected to the first to sixth external devices 201, 202, 203, 204, 205, 206. The control unit of the electronic device 100 transmits a wait request signal RS to the plurality of external devices 201, 202, 203, 204, 205, and 206 (S521).

The control unit may select an external device for transmitting the wait request signal RS based on a control command of a user applied to the electronic device 100. [ Alternatively, the controller may control the wireless communication unit 110 to transmit the wait request signal RS to all external devices wirelessly connected by the communication method.

Referring to FIG. 4C, the controller transmits the wait request signal RS to the first external device 210 to transmit the content. The display unit of the first external device 201 receiving the wait request signal RS outputs a first notification window 601. The first notification window 601 may include a graphic image for selecting whether to switch the first external device 201 to a standby state based on the wait request signal RS.

The display unit 502 may be displayed on the display unit of the first external device 201 when the first external device 201 is switched to the standby mode based on the wait request signal RS. The electronic device 100 receives a response signal including information indicating that the external device is switched to the standby mode in response to the standby request signal RS. The control unit may specify an external device to which the content is to be transmitted based on the response signal.

The external devices 201, 202, 203, 204, 205, and 206, which have received the wait request signal RS, switch to a standby state. Here, the wait signal means a standby state for receiving contents transmitted from the electronic device 100 and transmission information of the contents. When the external device is switched to the standby state, it is controlled such that the wireless signal received from the electronic device 100 or the sub-device among the wireless signals received from the outside is preferentially received. Prize

The controller of the electronic device 100 transmits the information on the sink device and the content transmission information to each designated sub device among the plurality of external devices in the standby state (S531). In FIG. 4B, the controller designates the first and fourth external devices 201 and 204 as sub devices, and transmits the first external device 201 to the second, third, fifth, and sixth external devices 202, 203, 205, and 206 as sink devices. The first, second, and third external devices are set as one group, and the fourth, fifth, and sixth external devices are set as one group.

4D, the electronic device 100 transmits the second information I2 of the second external device 202 and the second external information 202 of the third external device 203 to the first external device 201 designated as the sub- Of the third information I3. When the first external device 201 receives the second and third information I2 and I3, the first external device 201 outputs the second and third information I2 and I3 on the display unit. For example, the display unit of the first external device 201 may display a unique number identifying the device among the second and third information I2 and I3. However, the present invention is not limited to this, and the positions, representative names, and the like of the second and third external devices may be output on the display unit.

The control unit of the electronic device 100 transmits the transmission information of the content to the first external device 201 together with the information of the second external device 202 and the information of the third external device 203 And controls the wireless communication unit 110. The control unit may transmit the content transmission information (ID) to the fourth external device 204 along with the information of the fifth external device 205 and the information of the sixth external device 206, (110).

Referring to FIG. 4E, the display unit of the first external device 201 may output a notification window informing the transmission of the content transmission information (ID). Here, the content transmission information (ID) may include only partial information of the content. For example, the content transmission information (ID) may include a type and size of the content, and a graphic image representing the content. Each of the plurality of contents corresponds to the content transmission information (ID). The user of the second external device 202 can determine whether to receive the corresponding content through the content transmission information ID.

Referring to FIG. 4E, the display unit of the second external device 202 receiving the content transmission information ID outputs graphic images included in the content transmission information ID, The touch input of the user is received.

The sub-device designated as the first external device 201 receives content request information (RS) from the sink device (S522). That is, the second external device 202 uses the content transmission information (ID) to form information on the content to be received, selected by the user, into the content request information (RS), and transmits the content request information to the sub-device.

The first external device 201 receiving the content request information RS transmits the content selected on the basis of the content request information RS to the second external device 202 as the sink device . The content request information (RS) may include only content information selected by a user.

The electronic device is not involved in performing the functions of the sub device and the sink device while the sub device transmits and receives the content transmission information (ID), the content request information (RD), and the content with the sink device .

That is, the electronic device does not need to transmit the contents to a plurality of external devices at once because it does not need to transmit the contents and the sink device to the sub device and transmit the contents to the sink device It is unnecessary to transmit a large amount of data through the communication network of FIG.

After the content selected from the sink device is transmitted to the sink device, the sub device can store the desired content. Hereinafter, a control step of storing contents in the sub-device will be described in detail.

 FIG. 5A is a flowchart illustrating a control method of storing contents in a sub-device, and FIG. 5B is a conceptual diagram illustrating a control method of FIG. 5A according to an embodiment.

After the sub-device transmits the content to the sink device (S541), the electronic device 100 receives the delivery completion signal (CS) (S551). The transmission completion signal (CS) can be transmitted to the electronic device (100) by each of the sub devices and a plurality of sink devices classified into one group. Alternatively, the sub-device that has completed the transmission of the content to the plurality of sink devices may transmit the delivery completion signal (CS) to the electronic device (100).

5B, the display unit of the first external device 201 designated as the sub-device and the second external device 202 designated as the sink device transmit the completion signal CS to the electronic device 100, It is possible to output notification information indicating that the reception of the content to the sink device is completed.

When the reception completion signal CS is transmitted to the electronic device 100, the sub-device selects the stored content (S552). For example, the display unit of the first external device 201, which is the sub-device, outputs the content transmission information to select the content to be stored in the first external device 201. That is, the display unit of the first external device 201 receives a touch input of a user and outputs a graphic image corresponding to the content.

When the delivery completion signal CS is received, the electronic device 100 transmits a deletion control command DS to the sub-device (S553). The delete signal corresponds to a control command to delete content not selected by the sub-device. That is, when the first external device 201 receives the deletion control command DS, the first external device 201 deletes the content not selected by the user. Accordingly, the first external device 201 can store only selected contents among all contents received from the electronic device.

Meanwhile, although not shown in the drawing, when the transmission of the content selected by the sink device is completed, the first external device designated as the sub-device automatically deletes the content not selected by the user of the first external device . For example, the electronic device 100 may transmit a control command, which is activated when transmission of the content is completed to the sink device, to delete content that is not selected by the first external device, To the sub-device.

In addition, the sub-device may be de-assigned to the sub-device after delivering the content to the sink device. That is, the sub-device can delete the information about the sink device together with the unselected content.

Accordingly, the sub-device provides the contents to the sink device, and the sub-device can selectively store the content desired by itself.

6 is a conceptual diagram for explaining a control method of an electronic apparatus according to a transmission amount of contents. The control unit of the electronic device 100 detects the external device (S500). The electronic device 100 selects an external device to transmit the content (S501).

For example, the electronic device 100 may control the display unit 151 to output a graphic image representing a plurality of detected external devices. An external device to which the content is to be transmitted may be designated based on a touch input applied to the graphic image.

The control unit of the electronic device 100 compares the predicted transmission amount of the content with a predetermined reference amount (S502). Here, the predicted transmission amount may be calculated based on the capacity of the content and the number of external devices to simultaneously transmit the content. Also, the reference amount may be calculated according to a throughput according to a communication method of the electronic device 100 for transmitting the content.

If the estimated transmission amount is smaller than the reference amount, the electronic device 100 performs the step of transmitting the content to the plurality of external devices (S503).

If the expected transmission amount is larger than the reference amount, the plurality of external devices are classified as a sub device and a sink device (S504), and transmission information of the sink device information and the content is transmitted to the sub device (S522) . For example, the electronic device 100 can classify the external devices into a plurality of groups, and assign one sub-device to each group. The group is set so as not to affect the actual transmission amount when the contents are simultaneously transmitted to one group.

That is, the electronic device 100 according to the present invention determines whether or not to designate a sub-device to transmit the content on the basis of the capacity and the communication method of the content to be transmitted.

7 is a conceptual diagram for explaining a control method when an external device is out of the communicable area. The external device that receives the content is disposed in a communicable area with the electronic device 100 or the sub-device that transmits the content. If the distance between the external device and the electronic device 100 or the sub-device is distant, the content can not be transmitted stably.

The display unit of the second external device 202 outputs a second notification window 602 informing of the departure of the communicable area when the sink device leaves the communicable area. Also, the second notification window 602 may receive a selection of whether or not to continue the content reception when the second external device 202 enters the communicable area again. For example, when the second external device 202 receives a control command to suspend the reception of the content by the second notification window 602, the control unit transmits the control command to the electronic device 100 or the sub- . In this case, transmission of the control command can be performed using a method different from the communication method of transmitting the content.

Accordingly, the electronic device 100 or the sub-device can transmit the content to the second external device when the second external device is located again in the communicable area.

8A is a flowchart for explaining a control method of selecting an external device to transmit content based on face information included in the content, and FIGS. 8B and 8C are flowcharts for explaining a control method of FIG. It is a conceptual diagram.

8A and 8B, the memory 170 stores a face image 601 corresponding to the external device (S610). For example, the memory 170 stores information (e.g., a telephone number used in communication, a unique number of the device, representative information, etc.) that can specify the external device together with the face image 601 do.

The control unit of the electronic device 100 extracts the face data 601 'from the content when the content 600 to be transmitted to the external device is determined (S620). The controller compares the face image 601 with the face data 601 '(S630).

The controller selects an external device of the face image 601 matching the face data 601 '(S640). A plurality of face data may be extracted from the contents. In this case, the control unit searches the memory 170 for an intangible image matching each of the plurality of face data.

The content 600 is transmitted to the selected external device (S650). The control unit transmits the wait request signal RS to the external device based on the information stored together with the face image 601 judged to be substantially the same as the face data 601 '. When each of the external devices is switched to the standby state based on the wait request signal RS, the control unit controls the wireless communication unit 110 to transmit the content 600.

The display unit of the electronic device 100 displays a third notification window 603 for informing the external device to which the content 600 is delivered using the information stored together with the face image when the content 600 is delivered to an external device can do.

In the figure, the external device to extract the facial image included in the content is selected and the external device to transmit the content is selected. However, the external device is not limited thereto and the external device can be selected based on information included in various categories included in the content. For example, when the text included in the content matches the representative name of the contact information, the electronic device can transmit the content to an external device corresponding to the representative name.

According to the present exemplary embodiment, the controller selects an external device to transmit content using information included in the content, so that the controller can share content with an external device that is related to the content.

A control method of selecting an external device to share a plurality of contents will be described with reference to FIG. The display unit 151 of the electronic device 100 outputs a plurality of content images to select the transmitted content. The controller selects content to be transmitted to the external device based on a touch input applied to the plurality of content images.

The control unit controls the display unit 151 to output a setting window 610 for setting a criterion for selecting a shared object in order to select an external device to transmit the content. For example, the setting window 610 may be used to search for an external device located in the vicinity of the electronic device 100, transmit the selected external device to a predetermined device, select a device corresponding to a person included in the content, . ≪ / RTI >

The controller detects the face data of the person from the selected contents and compares the face data with the face data in substantially the same manner as described with reference to FIG. 8B. The display unit 151 outputs a fifth notification window 605 including an external device extracted based on information stored together with the portrait image.

In addition, the control unit may display in the fifth notification window 605 whether or not the extracted content can be transmitted to the external device. For example, the content can not be transmitted when the content is not located in an area capable of transmitting the content, or when the power of the external device is off.

The control unit transmits the selected content to the extracted external device based on the control command of the user. According to the present embodiment, content can be transmitted to an external device extracted based on a selected criterion using the selected content.

FIG. 9 illustrates a control method of inputting an external device to transmit content. The display unit 151 of the electronic device 100 outputs contents. The control unit 180 controls the display unit 151 to receive a predetermined touch input on the display unit and output a virtual keyboard for receiving a touch input to input a text. For example, the predetermined touch input may correspond to a long touch input.

The controller 180 searches the memory 170 for an external device corresponding to the text jelly based on the text input on the content. For example, the text may correspond to a telephone number, a representative name, a unique number, and the like of an external device.

The control unit 180 controls the wireless communication unit 110 to transmit the content to the external device when the external device is searched. Although not shown in the figure, the control unit can receive text corresponding to a plurality of external devices. On the other hand, if it is impossible to transmit the input to the external device, the display unit 151 may output a notification window including information indicating that transmission is impossible.

Accordingly, the user can directly designate an external device through which one content is to be transmitted.

The present invention described above can be implemented 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).
