Hereinafter, a related operation of the display unit 151 and the touch pad 135 will be described with reference to FIGS. 3A and 3B.

3A and 3B are front views of a portable terminal for explaining an operation state of a terminal related to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

At least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement for inputting such information, thereby being implemented as a keypad. Such a keypad may be called a so-called " soft key ".

FIG. 3A shows a touch input to a soft key through a front surface of a terminal body.

The display unit 151 may operate as an entire area or may be divided into a plurality of areas and operated. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. In the input window 151b, a soft key 151c in which a number for inputting a telephone number or the like is displayed is output. When the soft key 151c is touched, a number corresponding to the touched soft key is displayed on the output window 151a. When the first operation unit 131 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

FIG. 3B shows the input of a touch applied to the soft key through the rear surface of the terminal body. FIG. 3A shows a case where the terminal body is vertically arranged, and FIG. 3B shows a case where the terminal body is arranged horizontally.

When the soft keys 135c are touched through the touch pad 135, characters, numbers, symbols, etc. corresponding to the touched soft keys are displayed on the output window 135a. As described above, the touch input through the touch pad 135 is advantageous in that it is possible to prevent the soft key 135c from being covered by the finger when touching, compared with the touch input through the display unit 151. [ In the case where the display unit 151 and the touch pad 135 are formed to be transparent, the fingers located on the rear side of the terminal body can be visually confirmed, thereby enabling a more accurate touch input.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This will be useful for editing the image displayed on the display unit 151. [

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be, for example, activation or deactivation of the display unit 151 or the touch pad 135, and the like.

The proximity sensor 141 described with reference to Fig. 1 will be described in more detail with reference to Fig.

4 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

As shown in FIG. 4, when a pointer such as a user's finger, a pen, or the like approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen senses the proximity sensor and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to the distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

In FIG. 4, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance of d ₁ or more and less than distance d ₂ , it is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is positioned apart from the touch screen by a distance d ₃ or more, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity depth and proximity position of the pointer, and perform various operation control according to the various input signals.

5 is a conceptual diagram for explaining a control method for a touch operation in a form in which a pair of display units 155 and 156 are overlapped.

The terminal shown in this figure is a folder type terminal connected to a main body so that a folder portion is foldable. The first display unit 155 mounted on the folder unit may be of a light transmitting type or a transparent type such as TOLED or the second display unit 156 mounted on the main body may be a form that does not transmit light like an LCD. The first and second display units 155 and 156 may be configured as a touch screen capable of touch input, respectively.

For example, when a touch (a contact touch or a proximity-touch) to the first display unit or the TOLED 155 is detected, the control unit 180 determines whether the touch At least one of the images displayed in the TOLED 155 may be selected or run.

Hereinafter, with respect to the manner in which the information displayed on the other display unit or the LCD 156 is controlled when touching the TOLED 155 exposed to the outside in an overlapped form, a touch, a long touch, a long touch and drag ), And so on.

In the overlapped state (the mobile terminal is in a closed state), the TOLED 155 is arranged to overlap the lower side of the LCD 156. In this state, if a touch such as a long touch (for example, a touch that lasts for 2 seconds to 3 seconds) is detected in a manner different from the touch for controlling the image displayed on the TOLED 155 in advance, ) Causes at least one image of the image list displayed on the LCD 156 to be selected according to the sensed touch input. The result according to the execution of the selected image is displayed on the TOLED 155.

The long touch may also be used to selectively move a desired one of the entities displayed on the LCD 156 to the TOLED 155 (without performing any action thereto). That is, when a user selects one area of the TOLED 155 corresponding to a specific entity of the LCD 156 In the case of a long touch, the control unit 180 moves the corresponding object to the TOLED 155 to be displayed. The entity displayed on the TOLED 155 may also be displayed on the LCD 156 by a predetermined touch input to the TOLED 155, for example, flicking, swirling, and the like. In this figure, the menu No. 2 displayed on the LCD 156 is displayed on the TOLED 155.

If another input, for example, a drag, is detected in addition to the long touch, the control unit 180 is a function related to the image selected by the long touch. For example, a preview screen for the image is displayed on the TOLED 155, As shown in FIG. In this drawing, a case where a preview (male photograph) is performed on the menu No. 2 (image file) is illustrated.

The control unit 180 displays a selection cursor (or a selection bar) of the LCD 156 in the state that the preview screen is being output, while dragging toward another image is further performed on the TOLED 155 while maintaining the long touch And displays the image selected by the selection cursor on a preview screen (female photograph). Thereafter, when the touch (long touch and drag) ends, the controller 180 displays the first image selected by the long touch.

When the slide (the operation of the proximity touch corresponding to the drag) is detected together with the long proximity touch (the proximity touch continuing for at least 2 seconds to 3 seconds) to the TOLED 155 .

When a touch operation other than those described above is detected, the controller 180 can operate in the same manner as a general touch control method.

The control method for the touch operation in the overlapped form can be applied to a terminal having a single display. In addition, the present invention can be applied to a terminal different from a folder type having a dual display.

FIGS. 6A and 6B are views referred to the description of the proximity touch recognition area and the tactile effect generating area.

6A shows objects such as icons and menu items in a circular form for convenience of explanation. The area of the object displayed on the display unit 151 can be divided into a first area A in the center and a second area B surrounding the center area as shown in FIG. 6A. The first region A and the second region B can be configured to generate tactile effects having different intensities or patterns. For example, when the second region B is touched, a first vibration is output, and when the first region A is touched, a second vibration larger than the first vibration is output.

In the case where the proximity touch recognition area and the haptic area are simultaneously set in the area where the object is displayed, the haptic area where the tactile effect is generated and the proximity touch area where the proximity signal is detected Can be set differently. That is, the haptic area may be set narrower than the proximity touch recognition area, or the haptic area may be set wider than the proximity touch recognition area. For example, in (a) of FIG. 6A, the area including the first area A and the second area B may be a proximity touch recognition area, and the first area A may be set as a haptic area.

(N > 4) as shown in Fig. 6 (a), as shown in Fig. 6 (b) It is also possible to divide into two areas. Each divided region can be configured to generate a tactile effect with different intensities or patterns. Even when the area in which one object is displayed is divided into three or more areas, the haptic area and the proximity touch recognition area can be set differently according to the use environment.

The size of the proximity touch recognition area may be changed depending on the proximity depth to the display unit 151. [ That is, as shown in (a) of FIG. 6, the corresponding proximity touch recognition area may be gradually reduced to 'C', 'B', and 'A' according to the proximity depth to the display unit 151, Or the contiguous touch recognition area corresponding to the proximity depth to the display unit 151 may be gradually increased. In this case as well, the haptic area can be set to a constant size regardless of the proximity depth to the display unit 151, such as the 'H' area shown in FIG. 6B (b).

 In the case of dividing the area in which the object is displayed for the setting of the haptic area or the proximity touch recognition area, in addition to the concentric segmentation as shown in Fig. 6A, segmentation in the horizontal direction or vertical direction, radial segmentation, And various methods such as partitioning can be used.

Hereinafter, embodiments related to the chat control process in the terminal 100 configured as above will be described with reference to the accompanying drawings. It goes without saying that the embodiments described below can be used alone or in combination with each other.

The following embodiments can be more easily implemented when the display module 151 is configured as a touch screen.

<First Example >

The first embodiment of the present invention is characterized in that a video call or a voice call is selected when a user of a calling terminal sends a call to a receiving terminal by simultaneously transmitting a video call and a voice call from the calling terminal to the receiving terminal So that it is not necessary.

Hereinafter, with reference to FIG. 7 and FIG. 8, the operation process of the calling terminal according to the first embodiment of the present invention will be described in detail.

7 is a flowchart illustrating a procedure of providing a call of a calling terminal according to a first embodiment of the present invention.

FIG. 8 is a screen state diagram illustrating a procedure of setting a preferred call by the user of the calling terminal according to the present invention.

7 and 8, the controller 180 of the originating terminal selects the contact information of the recipient terminal to which the call is to be transmitted through the [S71], the input unit 130, or the touch screen 151 in the standby state [S72], a message for simultaneously transmitting the video call and the voice call is generated with the selected contact information [S73].

At this time, the contact information may include a name of a calling user, a mobile phone number, a home telephone number, a fax number, an e-mail address, and a homepage address.

In addition, the controller 180 may select the contact information from the phone book provided in the memory 160, and may receive input from the user.

In addition, the message is a call connection setup message (SETUP), and the controller 180 transmits a parameter for requesting the video call connection to the first bearer capability (BC ') of the call connection setup message Value, and sets a parameter value for requesting the voice call connection to the second BC.

The process of generating the message of the controller 180 will be described later in detail with reference to FIG. 8, and a process of selecting the contact information of the calling user and setting a preferred call to the selected contact information will be described in detail.

8 (b), the controller 180 displays the contact information list on the screen of the input unit 130 or the touch screen 151, as shown in FIG. 8 (a) The contact information 11 to be used to send a call is selected from the user through the touch panel 11 and a menu 12 for setting his or her preferred communication method is selected in the selected contact information 11, As shown in the figure, first and second windows 13a and 14b for selecting a preferred communication method among video communication and voice communication are displayed.

At this time, if the first window 13a for selecting a video call is selected from the user, the control unit 180 determines whether the user's preferred call method is displayed in the contact information 11 as shown in (d) Displays a first identifier (13b) indicating a communication method, and sets the preferred communication method to a video communication method in the contact information (11).

When the second window 14a for selecting a voice call is selected from the user, the control unit 180 determines whether the user's preferred call system is voice (voice) in the contact information 11 as shown in (e) A second identifier (14b) indicating that the user is in a communication mode, and sets the preferred communication mode to a voice communication mode in the contact information (11).

In addition, the controller 180 checks the number of video call connection times and the number of voice call connection times for the contact information 11 during a predetermined period, and sets a call having a high connection count to the preferred call method during the video call and voice call It is possible.

Hereinafter, with reference to Tables 1 to 3, a process of generating the message of step S73 and setting the preferred call mode of FIG. 8 to the message will be described in detail.

Table 1 shows an example of a structure of a call connection setup message for a conventional general voice call transmission.

Referring to Table 1, "bc repeat _ _ _ incl ind = 0 (0x0)" is an identifier indicating that the BC exists a single dog in the call connection set-up message or a plurality of presence. That is, since Table 1 shows a call connection setup message for transmitting only a conventional voice call, there is one BC for transmitting the voice call. Therefore, "0" is set to " bc_repeat_ind_incl & quot ;.

In addition, "bearer cap _ _1_ incl = 1" and "bearer cap _1 _" is the identifier indicating that the current second parameter value for the voice call connection in a 1 BC are invoked. And, "bearer cap _1 _" are the following syntax are various parameters for the voice call connection.

And, finally, "bearer _ cap _2_ incl = 0 " is the identifier indicating that the 2 BC there is not present the parameters values.

Referring to Table 2, "bc repeat _ _ _ incl ind = 0 (0x0)" is an identifier indicating that the BC exists a single dog in the call connection set-up message or a plurality of presence. That is, since there is a call connection setup message for transmitting only a conventional video call in Table 2, one BC exists for the video call transmission. Therefore, "0" is set to " bc_repeat_ind_incl & quot ;.

In addition, "bearer cap _ _1_ incl = 1" and "bearer cap _1 _" is the identifier indicating that the parameter value for the current video call connection in a 1 BC are invoked. And, "bearer cap _1 _" are the following syntax are various parameters for the video call connection.

And, finally, "bearer _ cap _2_ incl = 0 " is the identifier indicating that the 2 BC there is not present the parameters values.

Table 3 shows an example of a structure of a call connection setup message for simultaneously transmitting a video call and a voice call according to the present invention.

facility_incl = 0 (0x0)

Referring to Table 3, "bc repeat _ _ _ incl ind = 1 (0x0)" is an identifier indicating that the BC exists a single dog in the call connection set-up message or a plurality of presence. That is, since a call connection setup message for simultaneously transmitting a video call and a voice call is provided in Table 3, a first BC for transmitting the video call and a second BC for transmitting a voice call exist. Therefore, in the "repeat bc _ _ _ incl ind" to "1" is set.

In addition, "bearer cap _ _1_ incl = 1" and "bearer cap _1 _" is the identifier indicating that the parameter value for the current video call connection in a 1 BC are invoked. And the phrases "bearer_cap_1" are various parameter values for the video call connection.

And, an identifier that indicates the last time that "bearer _ cap _2_ incl = 1 " is the parameter values are set for voice call connection to claim 2 BC.

In this case, if the user's preferred communication method is a video communication method, the control unit 180 assigns priority to the first BC and sets parameter values for video call connection in the first BC And sets parameter values for voice call connection in the second BC.

Then, when the receiver receives the message, it can recognize that the caller's preferred communication method is the video call set in the first BC.

8 (e), if the user's preferred communication method is a voice communication method, the controller 180 sets parameter values for voice call connection within the first BC, Lt; / RTI &gt;

Then, when the receiver receives the message, it can recognize that the caller's preferred call method is a voice call set in the first BC.

The control unit 180 controls the wireless communication unit 110 to transmit the message generated in the process of Table 3 to the receiving terminal corresponding to the selected contact information 11 [S74].

The operation of the originating terminal has been described in detail in the first embodiment of the present invention.

Hereinafter, the operation of the receiving terminal according to the second embodiment of the present invention will be described in detail.

<2nd Example >

The second embodiment of the present invention is for allowing a receiving terminal to make a decision as to whether to make a video call or a voice call with the calling terminal.

Hereinafter, the operation of the receiving terminal according to the second embodiment of the present invention will be described in detail with reference to FIG.

9 is a flowchart illustrating a procedure of providing a call of a receiving terminal according to a first embodiment of the present invention.

9, when the call connection setup message is received from the originating terminal through the wireless communication unit 110 in the standby state [S91], the control unit 180 of the reception-side terminal 100 transmits the call Check whether the video call and voice call are both included in the connection setting message [S93].

That is, the control unit 180 first parses the "bc_repeat_ind_incl" identifier in the call connection setup message.

That is, the "bc _ repeat _ ind _ incl" to "1" if it is set, if that is the first BC and the 2 BC in the received call connection set up message, both present and wherein the first BC and And parses the parameter values set in the second BC.

That is, the controller 180 may be a "bearer _ cap _1_ incl" (claim 1 BC) parameter values and the "bearer _ cap _2_ incl" by parsing the parameter value set in (operation 2 BC), the first 1 BC set in , And recognizes that the voice call is included in the second BC.

As described above, if both the video call and the voice call are included in the call connection setup message (S94), the control unit 180 displays the first information 21 indicating the reception of the video call on the screen of the display module, And displays the second information 22 informing that the voice call is received (S95).

If the first and second information 21 and 22 are selected, the control unit 180 connects the selected call and performs a call operation for the connected call (S97).

Hereinafter, the process of displaying the reception of the video call and the voice call will be described in detail with reference to FIG.

FIG. 10 is a screen state diagram illustrating a process of displaying a video call and a voice call reception according to the present invention.

10 (a), when the video call is included in the first BC in the received message and the voice call is included in the second BC, the controller 180 determines that the call included in the first BC The first information 21 indicating the reception of the video call is displayed prior to the second information 22 informing of the fact that the voice call is received by the caller so that the user of the receiving- The information 21 can be selected.

10 (b), the controller 180 controls the display size, the display color, and the font size of the first information 21 indicating the reception of the video call, The first information 21 can be selected by the user of the receiving terminal.

10 (c), the control unit 180 displays an identifier 23 for indicating that the video call method is the call method preferred by the caller in the first information 21, So that the user of the receiving terminal can select the first information 21.

The control unit 180 may also use the motion detection sensor 142, the brightness detection sensor 143, the distance detection sensor 144, and the thermal detection sensor 145 shown in FIGS. 11 to 14 The video call and the voice call can be selected, and the video call and the voice call can be switched.

11 is a flowchart of a second embodiment of a video call and voice call conversion process using a motion detection sensor according to the present invention.

Referring to FIG. 11, the controller 180 displays the first and second information 21 and 22 in step S95 of FIG. 9 in step S111, If motion is detected in step S112, it is determined that the first information 21 is selected, the video call is connected (S113), and a call operation for the connected video call is performed (S114).

In this case, the first movement may be a movement corresponding to an operation for making a video call while the user holds the terminal body, or may be a preset movement by a user.

If the second motion is sensed through the motion sensor 142, the control unit 180 determines that the second information 22 is selected, connects a voice call (S116) , And can perform a call operation for the connected voice call (S117).

In this case, the second movement may be a movement corresponding to an operation for making a voice call while the user holds the terminal body, or may be a preset movement by the user.

If the first motion is detected through the motion detection sensor 142 during the video call in step S114, the control unit 180 may switch the video call to the voice call in step S119.

If the second motion is detected through the motion detection sensor 142 during the voice call in step S117, the control unit 180 may switch the voice call to the video call in step S121.

12 is a flowchart of a second embodiment of a video call and voice call conversion process using the brightness sensor according to the present invention.

12, the controller 180 displays the first and second information 21 and 22 of step S95 of FIG. 9 (S131) and controls the brightness sensor 143 The light brightness is measured [S132].

If the brightness measured through the brightness sensor 143 is less than the reference value (S133), the controller 180 regards the second information 22 as being selected, connects the voice call (S134) And can perform a call operation for the connected voice call (S135).

At this time, the reference value may be a brightness value in a state in which the environment surrounding the terminal is shortened and video communication is impossible.

That is, if the brightness of the surroundings of the terminal is less than the reference value, since the environment around the terminal is shortened, the video call can not be performed, and thus the controller 180 directly provides the voice call to the user.

On the other hand, if the brightness measured through the brightness sensor 143 exceeds the reference value, the control unit 180 determines that the first information 21 is selected because the brightness around the current terminal is suitable for the video call. , A video call is connected (S136), and a call operation for the connected video call is performed (S137).

If the brightness around the terminal re-measured by the brightness sensor 143 during the voice communication in step S135 is greater than the reference value (S138), the controller 180 determines that the brightness around the current terminal is appropriate for the video call Because of the brightness, the voice call can be switched to the video call [S139].

If the brightness of the surroundings of the terminal re-measured through the brightness sensor 143 during the video call in step S137 is less than the reference value (S140), the controller 180 determines that the brightness around the current terminal Since the call is impossible, the video call can be switched to the voice call [S141].

13 is a flowchart of a second embodiment of a video call and voice call conversion process using the distance sensor according to the present invention.

Referring to FIG. 13, the controller 180 displays the first and second information 21 and 22 of step S95 of FIG. 9 (S151) Measure the distance [S152].

If the distance measured through the distance sensor 144 is less than the reference value (S153), the control unit 180 regards the second information 22 as being selected, connects the voice call (S154) And can perform a call operation for the connected voice call [S155].

At this time, the reference value is a distance value suitable for the video call between the user and the user.

That is, if the distance between the terminal body and the user is less than the reference value, the user grasps the terminal body and touches his / her ear to the sound output module 152, or the distance between the user and the terminal is very close, It is impossible to provide a voice call to the user.

If the distance measured by the distance sensor 144 exceeds the reference value, the controller 180 determines that the first information 21 is selected because the distance between the terminal and the user is a distance suitable for the video call The video call is connected (S156), and the call operation for the connected video call is performed (S157).

If the distance re-measured through the distance sensor 144 during the voice communication in step S155 exceeds the reference value (S158), the controller 180 determines that the distance between the current terminal and the user is a distance The voice call can be switched to the video call (S159).

If the distance re-measured through the distance sensor 144 during the video call in step S157 is less than the reference value [S160], the controller 180 determines that the distance between the current terminal and the user is not a video call It is possible to convert the video call into a voice call (S161).

FIG. 14 is a flowchart of a second embodiment of a process for switching a video call and a voice call using the heat sensing sensor according to the present invention.

14, the controller 180 displays the first and second information 21 and 22 of step S95 of FIG. 9 in step S171, Is measured [S172].

If the temperature measured through the heat sensor 145 is not equal to the reference value (S173), the control unit 180 regards the first information 21 as being selected, connects the video call (S174) , And can perform a call operation for the connected video call (S175).

At this time, the reference value is a temperature value corresponding to the body temperature of the user.

That is, if the measured temperature is not equal to the reference value, the user does not hold the terminal main body at present and the voice call is not possible in a state where the terminal main body is not gripped.

If the temperature measured through the heat sensor 145 is equal to the reference value, the control unit 180 regards the second information 22 as being selected because the current user has gripped the terminal main body, (S176), and performs a call operation for the connected voice call (S177).

If the temperature re-measured through the heat sensor 145 during the video call in step S175 is equal to the reference value (S178), the control unit 180 determines that the current user has gripped the terminal main body, The call can be switched to a voice call [S179].

If the temperature re-measured through the heat sensing sensor 145 during the voice communication in step S177 is not equal to the reference value (S180), the control unit 180 determines that the current user does not hold the terminal body The user can switch the voice call to the video call because the video call is suitable when the user does not hold the terminal body [S181].
