4 is a flowchart illustrating a method of controlling an operation of a portable terminal according to an exemplary embodiment of the present invention. 4, when the touch input or the key input is not present for a predetermined time, or when the user inputs a command, the control unit 180 controls the touch lock touch lock state (S200). When the touch lock state is set, the effect sound corresponding to the setting of the touch lock state can be output or a tactile effect can be generated.

In a case where a communication event such as reception of a response to a transmitted message or a mail, reception of a notification message from a social network service site occurs (S205) while the touch lock state is set, And outputs a notification signal indicating the occurrence (S215). At this time, the notification signal can be output as an acoustic signal, an optical signal, or the like. Depending on the use environment, notification information indicating the occurrence of a communication event may be displayed on the display unit 151. [

After outputting the notification signal, the control unit 180 determines whether the state is the state held by the user (S220). Here, the state held by the user means a state in which the user holds the portable terminal 100. Whether or not the user has grasped the portable terminal 100 can be determined according to a change in a detection signal output from a touch sensor, a temperature sensor, a pressure sensor, and a motion sensor provided in the main body. Depending on the setting state, a case where the user's hand, face or the like touches the main body may be regarded as a state held by the user.

If it is determined in step S220 that the user has grasped the state, the controller 180 cancels the touch lock state (S220) and controls the operation mode to enter the operation mode related to the communication event (S225). Examples of the operation mode related to the communication event include an acknowledgment of the received message or e-mail contents, confirmation of the contents of the notification message, a mode for transmitting a message to the other party related to the message or e-mail, it means.

Even when the touch lock state is canceled, the effect sound corresponding to the cancellation of the touch lock state can be output or a tactile effect can be generated.

In this manner, when the user grasps the portable terminal 100, the user can immediately enter the related operation mode at the same time as the touch lock state is canceled.

5 is a flowchart illustrating a method of controlling an operation of a portable terminal according to another embodiment of the present invention.

5, when a function such as moving picture playback, multimedia file playback, DMB viewing, or other broadcast viewing is selected (S300), the controller 180 executes the selected function and executes the selected function On the display unit 151 (S305). At this time, examples of the displayed operation screen include a screen on which a moving picture is reproduced, a broadcast screen, and the like.

In a state where the operation screen is displayed, the control unit 180 determines whether the state is the state held by the user (S310). As described above, the state held by the user means that the user holds the portable terminal 100.

If it is determined in step S310 that the user has grasped the selected function, the selected function continues to be executed until the end of the selected function (S315). However, if it is not detected that the user is gripped, the controller 180 stops execution of the selected function (S320) and sets the touch lock state (S325).

When the touch lock state is set again, the control unit 180 releases the touch lock state (S335) and executes the suspended function again (S340).

According to this process, the touch lock state can be set or the set touch lock state can be released depending on whether or not the user grasps the state.

In the above-described embodiment, the touch lock state is set or released according to whether or not the user grasps the state. Alternatively, the touch lock state can be set or released by various methods.

For example, eye-tracking may be used. Eye Tracking is a technology for tracking the user's eyes by recognizing the user's eyes by analyzing the images input through the camera, and can grasp the user's gaze position in real time using eye tracking. When the user turns his or her gaze on the screen while the moving picture is being played back using such a line-of-sight tracking, the moving picture is stopped and the touch-lock state is set. When the user turns his or her eyes to the screen again, Can be configured to be performed.

Also, the time at which the touch lock state is set may be automatically adjusted according to the frequency of using the portable terminal. For example, when there is no user input for 30 seconds, a state in which the touch lock state is set, and a situation in which the touch lock state is released within one minute after the touch lock state is set may be repeated a number of times. In this case, it is determined that the frequency of use of the user is increased, so that the time at which the touch lock state is temporarily set is doubled, and the time at which the touch lock is again set when the frequency of use of the user becomes the original state is set to the original time You can use the return method. By using this method, the time at which the touch lock is set can be appropriately adjusted according to the frequency of use by the user.

6 (a) shows a screen 400 in which the touch lock state is set and the screen is turned off (OFF) because there is no user input for a predetermined time. When the touch lock state is set, no operation is performed on the touch input through the display unit 151, and the touch lock state can be canceled by inputting the touch lock release key.

6B, after the touch lock is set up, a communication event such as a response message is received or a notification message is received from the social network service site, and thus, the user holds the portable terminal 100 in his / State, that is, the state that the user has grasped. In this manner, when the user grasps the state, the set touch lock state is automatically canceled, the operation mode is switched to an operation mode capable of creating a message to be transmitted to the other party of the generated communication event, and the screen 410 corresponding to the switched operation mode is displayed. Is displayed.

Similarly, in FIG. 7A, when the user grasps the screen 420 on which the touch lock is set, as shown in FIG. 7B, enters an operation mode in which a response message can be confirmed, A screen 430 corresponding to the entered operation mode is displayed.

As described above, when the user enters a state in which the specific communication event has occurred, the set touch lock is automatically canceled. Further, according to the function or the communication event that occurred before the touch lock state was set, it is possible to immediately enter the related operation mode at the same time as releasing the touch lock.

For example, if a user leaves a message on a social network service site using the mobile terminal 100 and then leaves a response to the user in a state of being switched to a touch lock state, And transmits a notify message to the terminal 100. At this time, when the user grasps the portable terminal 100 for confirmation, the touch lock is automatically released, and the user can automatically switch to the operation mode in which the message can be transmitted to the social network service site or the other party. In addition, after the transmission of SMS (Short Message Service), MMS (Multimedia Messaging Service), e-mail, etc., the touch lock state is set, and after receiving a response message, the user holds the portable terminal 100 in his hand , The user can automatically release the touch lock state and switch to the message confirmation mode.

8 (a) shows a screen 440 in which the portable terminal 100 is put down during the moving picture playback and the touch lock state is set. When the user picks up the portable terminal 100 again in this state, the touch lock state is automatically released as shown in FIG. 8B, and a screen 450 ) Is displayed,

In this way, when the user holds the portable terminal 100 and the portable terminal 100 is put down while the specific function is being performed, the execution of the specific function is suspended and the touch lock state is set. Once picked up, you can redo the function that was stopped at the same time you release the touch lock state.
