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.

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 may be determined according to the current state of the mobile terminal 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.

[ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal 100 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.

2 is a flowchart illustrating a control method of the mobile terminal 100 according to an embodiment of the present invention.

Referring to FIG. 2, the controller 180 enters a remote control mode to select an object to be controlled (S210). The remote control mode in the present invention is a mode in which at least one of searching for another electronic device capable of forming a wireless communication link and searching the electronic device is selected as a control object, a function selection related to a selected control object, And the like, can be performed based on the multi-touch pattern.

The control unit 180 can enter the remote control mode when a predetermined input is received. The user can enter the remote control mode only when receiving the predetermined input, thereby preventing the user from entering the remote control mode differently from the intention of the user. At this time, the control unit 180 may enter the remote control mode of the display unit 151, which is in the activated state, and may switch all or a part of the display unit 151 to the inactive state. In addition, the controller 180 may output a predetermined visual effect, auditory effect, tactile effect, or the like so that the user can recognize that the user enters the remote control mode.

Next, the control unit 180 selects at least one of the other electronic devices having a wireless communication link with the wireless communication unit 110 as an object to be controlled (S220). If there are a plurality of other electronic devices having a wireless communication link, the control unit 180 may select at least one of the electronic devices to be controlled according to a predetermined input. At this time, the predetermined input to select the control object may be various types of input such as touch input, voice input, and the like. For example, the control unit 180 can select a control object corresponding to a relative difference between touch information of the first touch, touch information of the second touch, or touch information between the first touch and the second touch.

At this time, the control unit 180 can release the wireless communication link with other electronic devices other than the selected control target. On the other hand, when there is only one other electronic device in which the wireless communication link is formed, the control unit 180 can select the electronic device as a control target without receiving a separate input.

Next, the control unit 180 receives a multi-touch input including a first touch and a second touch different from the first touch through the display unit 151 (S230). In the present invention, multi-touch refers to a touch operation that occurs simultaneously in at least two positions of the display unit 151. The multi-touch includes a first touch and a second touch, and the first touch and the second touch may have the same or different intensities, respectively. Also, the first touch and the second touch may have one or two or more touch positions, respectively. For example, the first touch may be the detection of the user, and the second touch may be received by the user's interruption. Alternatively, the first touch may be the user's left hand, and the second touch may be received by the user's right hand. However, the present invention is not limited thereto, and the first touch or the second touch may be received by a tool such as a stylus pen and not the user's body.

The display unit 151 is provided with a touch sensor, and the touch sensor can detect a touch position, an area, a pressure, and the like on the display unit 151. For example, a resistive-type (or pressure-sensitive) touch sensor can sense a pressure with a touched position through a change in resistance value according to a touch. As another example, the electrostatic touch sensor can sense the area together with the touched position by changing the capacitance value according to the touch. Hereinafter, the pressure or area according to the touch will be referred to as " intensity " of the touch.

Next, the controller 180 selects a function corresponding to the strength of the first touch among the functions related to the selected control object (S240). Specifically, the controller may select different functions according to the intensity of the first touch. If a touch sensor included in the display unit 151 can sense the intensity from level 0 to level 10, a rule for selecting another function each time the level is increased by one level is detected by the controller 180 or the memory 170). For example, when the control target is the TV, the volume control function of the TV is selected when the intensity of the first touch corresponds to the level 1, and the volume control function of the TV is selected when the intensity of the first touch is equal to the level 2 . Even if the first touch has the same intensity, the function to be selected corresponding to the controlled object may be changed as well.

Next, the control unit 180 may transmit the control signal corresponding to the selected function and the touch information of the second touch through the wireless communication unit 110 to the control object through step S240 (S250). Here, the touch information may be at least one of pressure, area, holding time, position, number of positions, direction, distance, or tap count. For example, when the power control function of the TV is selected according to the intensity of the first touch, the controller 180 turns off the power of the TV when receiving the second touch sliding to the left and receives the second touch sliding to the right A control signal for turning on the power of the TV can be generated and transmitted to the TV. The TV receiving the control signal performs an operation of turning the power on / off according to the control signal.

Information on which control object to select according to the touch information of each of the first touch and the second touch and to which degree of the function of the control object to be controlled may be stored in advance in the memory 170, The information may be changed based on user input.

3 is a view for explaining an example in which the mobile terminal 100 related to the present invention receives a multi-touch and enters a remote control mode.

The control unit 180 can enter the remote control mode upon receipt of a predetermined input. At this time, the predetermined input is a first touch (T1) and a second touch (T2) that last for more than a predetermined time at two or more different positions on the display unit 151 as shown in . If either the first touch T1 or the second touch T2 is released before reaching the preset time, the controller 180 may block the entry into the remote control mode. So that the mobile terminal 100 does not perform an operation different from the intention of the user by allowing the multi-touch to enter the remote control mode only when the multi-touch matches the predefined pattern.

Meanwhile, the display unit 151 at the time when the multi-touch is received before entering the remote control mode may be in an inactive state in which no light, information or object is displayed as shown in FIG. 3A, But may be an active state in which an operation screen related to a predetermined application program is displayed. Of course, even when the display unit 151 is in the inactive state, the controller 180 may have a layer structure with the display unit 151 or may receive the touch input through a touch sensor formed integrally.

In addition, when the display unit 151 receives a predetermined input while the display unit 151 is in an active state, the control unit 180 may enter the remote control mode and may switch all or a part of the display unit 151 to the inactive state. This is because the mobile terminal 100 related to the present invention can remotely control the control target by using only the multitouch without the user viewing the display unit 151. [ In addition, the control unit 180 may search for another electronic device that can establish a wireless communication link with the wireless communication unit 110 while entering the remote control mode. Another electronic device according to the present invention is a device that receives a predetermined control signal from the mobile terminal 100 by forming a wireless communication link with the wireless communication unit 110 of the mobile terminal 100 or transmits predetermined data to the mobile terminal 100 Means an electronic device capable of transmitting.

In addition, when the controller 180 enters the remote control mode, the controller 180 may inform the user that the remote control mode is entered. This guidance may include, for example, the sound output unit 152 as shown in FIG. 3 (b) (For example, enter the remote control mode) through the haptic module 153, or output in a tactile format through the haptic module 153 as shown in FIG. 3 (c). Alternatively, the control unit 180 may display at least one object (A, B, C, B) indicating a list of control objects formed with the wireless communication link with the wireless communication unit 110, Can be displayed on one side. In addition, the controller 180 can maintain the remote control mode until another command is received even if the multi-touch is released after entering the remote control mode.

4 is a diagram for explaining another example in which the mobile terminal 100 related to the present invention receives a multi-touch and enters a remote control mode.

3, the controller 180 enters the remote control mode when the locus of the first touch T1 and the second touch T2 corresponds to a predefined second pattern .

More specifically, the controller 180 determines whether the positions of the first touch T1 and the second touch T2, which are spaced apart from each other by a predetermined distance as shown in FIG. 4A, When the multi-touch is received, the remote control mode can be entered. 4A and 4B illustrate a multi-touch in which the first touch T1 and the second touch T2 are brought close to each other along the vertical direction. However, in the present invention, The position of the multi-touch or the first touch T1, in which the first touch T1 and the second touch T2 are further apart from each other along the vertical direction, It is apparent to those skilled in the art that a multi-touch of various patterns such as multi-touch approaching the position of the first touch T1 may be predefined as a second pattern for allowing the multi-touch to enter the remote control mode.

4 (c) to (e), when the remote control mode is entered, the controller 180 may inform the user that the remote control mode is entered, (d), and a detailed description thereof will be omitted.

5A and 5B illustrate an example in which the mobile terminal 100 related to the present invention selects a controlled object after entering the remote control mode. At this time, it is assumed that the searched other electronic device is a TV and a vacuum cleaner. 5A and 5B illustrate different sizes of the circles corresponding to the intensities of the first touch T1 and the second touch T2. That is, the larger the size of the circle means that at least one of the intensity of the touch, that is, the pressure or the area, is larger than when the size of the circle is smaller.

The control unit 180 can select any one of a plurality of control objects that can be controlled remotely according to the difference in intensity between the first touch T1 and the second touch T2 included in the multi-touch.

Specifically, the controller 180 compares the first touch T1 and the second touch T2 having different intensities as shown in (a) of FIG. 5A to compare the first touch T1 and the second touch T2, The control target selection mode can be entered. Here, the control target selection mode means a mode in which any one of a plurality of electronic devices forming a wireless communication link with the wireless communication unit 110 is selected as a control target based on multi-touch.

For example, when the intensity of the second touch T2 is greater than the first touch T1 by a predetermined threshold value or more and is released for a predetermined time or longer and then released, An indicator for informing the user that any one of a plurality of electronic devices forming the wireless communication link (e.g., TV) is selected, or a voice can be output.

If the state of the second touch T2 is greater than the first touch T1 by a predetermined threshold value or more for a predetermined period of time or longer and then released as shown in (c) of FIG. 5, It is possible to output, in a voice format or the like, information for notifying that another (e.g., a vacuum cleaner) of a plurality of electronic devices forming the wireless communication link is selected as the control target, as shown in (d)

Referring to FIG. 5B, the controller 180 selects one of the plurality of electronic devices having the wireless communication link to be controlled according to the step in which the intensity difference between the first touch T1 and the second touch T2 belongs .

5B, when the first touch T1 and the second touch T2 have the same intensities as shown in FIG. 5B, the controller 180 determines whether the second touch T2 When the intensity of the first touch T1 and the second touch T2 correspond to 'level 1', the control unit 180 determines that the difference between the first touch T1 and the second touch T2 is' It can be notified that the TV to be controlled is selected. 5B, when the intensity difference between the first touch T1 and the second touch T2 is 'level 1' as shown in FIG. 5B, the intensity of the second touch T2 further increases, if the difference between the intensities of the first touch T1 and the second touch T2 is increased to 'level 2' as shown in FIG. 5C, the control unit 180 determines that the control object It can be notified that the cleaner has been selected.

On the other hand, in FIGS. 5A and 5B, it is shown that the TV next cleaner is guided as a remotely controllable control object, but this is only an example, and the TV following the cleaner may be guided. The order of control objects to be guided by the control unit 180 may be set differently depending on the distance to the mobile terminal 100, the frequency of remote control, the priority set by the user, and the like. 5A and 5B, the intensity of the second touch T2 is shown to be greater than the intensity of the first touch T1. On the other hand, when the intensity of the first touch T1 is greater than the intensity of the second touch T2, It is to be understood that the control object can be selected in the same manner even if it is larger than the reference value.

6A and 6B illustrate another example in which the mobile terminal 100 related to the present invention selects at least one of the other electronic devices searched for as objects to be controlled. More specifically, FIGS. 6A and 6B illustrate a state in which objects (A, B, C, and B) showing a list of other electronic devices searched as shown in FIG. 3D are displayed on one side of the display unit 151 An operation of selecting one of the control objects according to the intensity difference between the first touch T1 and the second touch T2 is illustrated.

Specifically, when the TV corresponding to the first object A is selected as the object to be controlled and the intensity of the second touch T2 increases as shown in (b) of FIG. 6A, The controller 180 can compare the intensities of the first touch T1 and the second touch T2 with each other. If it is determined that the intensity difference between the first touch T1 and the second touch T2 is equal to or greater than a predetermined threshold value, It is possible to select a cleaner to be controlled corresponding to the second object B. [ It is apparent to those skilled in the art that although not shown, it is possible to sequentially select the objects to be controlled corresponding to the third object C and the fourth object D through the same method. Accordingly, by inputting the intensity of the second touch (T2) larger than the intensity of the first touch (T1), the user sequentially selects the control object in the order from the first object (A) to the fourth object .

On the other hand, when the air conditioner corresponding to the fourth object D is selected as the control object as shown in FIG. 6B, when the intensity of the first touch T1 increases as shown in FIG. 6B, 180 may compare the intensities of the first touch T1 and the second touch T2 with each other. If it is determined that the intensity difference between the first touch T1 and the second touch T2 is equal to or greater than a predetermined threshold value, It is possible to select a cleaner to be controlled corresponding to the third object C. [ It is apparent to those skilled in the art that although not shown, it is possible to sequentially select the objects to be controlled corresponding to the second object B and the first object A through the same method. Accordingly, the user can sequentially select the objects to be controlled in the order from the fourth object D toward the first object A by inputting the intensity of the first touch T 1 larger than the second touch T 2 .

In FIGS. 5 and 6, the remote control type object capable of operating the selected control target function is not displayed on the display unit 151, but the scope of the present invention is not limited thereto. That is, according to the present invention, the user can control the function of the object to be controlled without viewing the display unit 151 by using the multi-touch. However, the control unit 180 controls the operation of the predetermined object The display unit 151 can display the object. For example, the control unit 180 may display on the display unit 151 an object corresponding to each button of the remote controller that can control the function of the selected control object.

FIG. 7 is a diagram for explaining an example in which the mobile terminal 100 related to the present invention selects a function for performing remote control on a control object according to the position of the first touch T1.

The control unit 180 can divide the display unit 151 into at least two areas based on a predetermined virtual line when the selection of the control target to be controlled remotely is completed. Such a false line may not actually be displayed on the display unit 151. In the memory 170, a specific function of the control object corresponding to each of the divided areas can be set in advance. At this time, a plurality of functions related to the control object may be set in each of the divided areas.

Referring to FIGS. 7A and 7B, the first area a1 and the second area a2, which are upper and lower boundaries on the basis of the imaginary line 201, can be identified. If the selected control target is a TV, the first area a1 is previously set to correspond to the volume and channel control function of the TV, and the second area a2 is set to on- And can be set in advance to correspond to the function. Alternatively, when the selected control target is a robot cleaner, the first area a1 is previously set to correspond to the suction force control function of the robot cleaner, and the second area a2 is set to the movement pattern setting function of the robot cleaner It can be set in advance as a corresponding one.

For example, when the user who has selected the TV as the control target wants to change the volume or the channel, the first touch T1 is placed in the first area a1 as shown in FIG. 7A, When the selected user desires to change the moving pattern of the cleaner, the function related to each control object can be easily selected by placing the first touch T 1 in the second area a 2 as shown in FIG. 7B , Thereby enhancing user convenience.
