Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a U.S. National Stage application under 35 U.S.C. §371 of an International application filed on Sep. 15, 2014 and assigned application number PCT/KR2014/008581, which claimed the benefit of a Korean patent application filed on Sep. 13, 2013 in the Korean Intellectual Property Office and assigned Serial number 10-2013-0110451, the entire disclosure of each of which is hereby incorporated by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to a device and method for displaying application-related information and executing the application on a lock screen. 
     BACKGROUND 
     With the rapid development of communication technologies, the number of functions of a portable device is increasing, and accordingly, various user interfaces (UIs) and various functions using such UIs are being developed. 
     In particular, a portable device with a touch screen has a lock/unlock function to limit unnecessary input errors in a standby state or to prevent other people from using the portable device, wherein the lock/unlock function is based on various methods. Generally, the portable device can perform the lock function when the lock function was set in advance by a user. 
     The portable device in which the lock function was set activates the lock function when no user input is received for a predetermined time. That is, when a user makes no input for a predetermined time while using a specific function of the portable device, the portable device deactivates the screen or function to enter a lock state. In the lock state, the screen of the portable device is turned off or a predetermined image is displayed. 
     Meanwhile, along with an increase in diversity of user demands, a need for more efficiently using the screen space of the portable device is increasing. Accordingly, in order to raise the effective value of the lock screen of the portable device while satisfying such various user demands, in addition to limiting touch input errors and restricting access, a method for combining various services of the portable device with additional functions is needed. Also, user convenience needs to be a high priority in implementing the method. 
     The portable device activates the lock function whenever a user input waiting time elapses. Generally, the portable device releases a lock mode, for example, a touch screen hold state, according to a pre-defined method. After the lock mode is released, a home screen or a recently used application is displayed. Therefore, if the user wants to use a specific function when the portable device is in a locked state or in a deactivated state, the user needs to release the lock mode using a predetermined lock release method, and then perform a procedure for entering a menu for executing the function, which causes the user&#39;s burden or inconvenience. For this reason, a method for easily releasing locking while performing user authentication is needed. 
     Also, the portable device needs to raise visibility for information transfer by expressing information in various ways while providing the user with a new and pleasant interface, instead of focusing on limiting any unnecessary touch input and displaying a screen for receiving a lock release comman. 
     The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

       FIG. 1  is a block configuration diagram of a portable device according to an embodiment of the present disclosure. 
     Referring to  FIG. 1 , a portable device  100  may connect to an external electronic device (not shown) using at least one of a communication module  120 , a connector  165 , and an earphone connecting jack  167 . The external electronic device may include an earphone, an external speaker, a universal serial bus (USB) memory, a battery charger, a cradle/dock, a digital multimedia broadcasting (DMB) antenna, a mobile payment system, healthcare equipment (a blood glucose meter, etc.), a game, a vehicle navigation system, and the like, which can be removably connected to the portable device  100  through a line. Also, the portable device  100  may include a Bluetooth communication apparatus, a near field communication (NFC) apparatus, a Wi-Fi direct communication apparatus, a wireless access point (WAP), and the like, which can be connected to the external electronic device in a wireless fashion. Also, the portable device  100  may be connected to another portable device or electronic device (for example, a mobile phone, a smart phone, a tablet personal computer (PC), a desktop PC, and a server) in a wired/wireless fashion. 
     Referring to  FIG. 1 , the portable device  100  may include at least one touch screen  190  and at least one touch screen controller  195 . In the following description, a display unit and a display controller are assumed to be the touch screen  190  and the touch screen controller  195 , respectively. Also, the portable device  100  may include a controller  110 , a communication module  120 , a camera module  150 , an input/output module  160 , a sensor module  170 , a storage unit  175 , and a power supply unit  180 . 
     The controller  110  may include a central processing unit (CPU)  111 , a read only memory (ROM)  112  that stores control programs for controlling the portable device  100 , and a random access memory (RAM)  113  that stores signals or data received from the outside or is used as a memory area for tasks being performed by the portable device  100 . The CPU  111  may include a single core, a dual core, a triple core, or a quad core. The CPU  111 , ROM  112 , and RAM  113  may be connected to each other through internal buses. 
     Also, the controller  110  may control the communication module  120 , the camera module  150 , the input/output module  160 , the sensor module  170 , the storage unit  175 , the power supply unit  180 , the touch screen  190 , and the touch screen controller  195 . 
     Also, the controller  110  may control object-related operation on a lock screen that is configured with a plurality of executable graphic objects or graphic items and information related to the objects on the touch screen  190 . 
     In detail, the controller  110  may sense a user input for activation, such as operation of pressing a home button or operation of making a user gesture, when the portable device  100  is in a deactivated state, that is, in an off-screen state. Then, the controller  110  may display a lock screen configured with an area in which a plurality of executable objects are arranged and an information display area having a restricted viewing range with respect to each object. If a user input is detected on the information display area when the lock screen is displayed, the controller  110  may change and display information according to the user input, and if a user input is detected on the area in which the objects are arranged, the controller  110  may execute an application linked to an object to which the user input is applied. According to the present disclosure, there is provided a lock screen on which one or more applications are arranged so that other people as well as the owner of the portable device  100  can use some of functions of the applications. 
     In the current embodiment, the lock screen may be a screen that is displayed before the lock function is released in a screen-off state. The lock screen may be different from a lock release screen for receiving a lock release command according to one of various locking methods, such as a pattern input method, a personal identification number (PIN) input method, a password input method, etc. The lock screen according to the present disclosure is also called a glance view screen. On the glace view screen, a plurality of executable objects and outline information related to the objects may be displayed. Information related to objects may be classified according to level. For example, information related to objects may be classified into a primary level and a secondary level. For example, information of the primary level may be information that is irrelevant to leakage of personal information, and information of the secondary level may be information with content related to personal information. 
     Accordingly, in an embodiment of the present disclosure, when a user does not want leakage of personal information stored in the portable device  100  or unauthorized use of the portable device  100  by other people, the user can set a range of information that is displayed on the lock screen such that only information of the primary level is displayed on the lock screen. Also, according to an embodiment of the present disclosure, when a command for executing one of the plurality of executable objects is received, a lock release screen requesting a user to input a lock release command may be displayed in order to prevent unauthorized use of the portable device  100  by other people. That is, by performing user authentication before an application related to the selected object is executed, it is possible to allow a user to easily access desired information on the lock screen, while preventing other people except for the owner of the portable device  100  from accessing personal information of the application. 
     Also, the controller  110  may detect a user input when a plurality of objects or items are displayed on the touch screen  190 , wherein the user input may be a touch input of touching an object with touchable user input means such as an input unit or the user&#39;s finger, a gesture input of making the touchable user input means approach the object, or a gesture input of locating the touchable user input means close to the object. Then, the controller  110  may identify the object corresponding to a location at which the user input is made on the touch screen  190 . The user input made on the touch screen  190  may be one of a direct touch input of directly touching the object, and a hovering input which is an indirect touch input of approaching the object within a predetermined distance to the object without directly touching the object. For example, if a user locates the user input means close to the touch screen  190 , an object located near the user input means may be selected. Herein, the user input may be a switch/button input through the button  161  or the keypad  166 , a voice input through the microphone  162 , etc., as well as a user input through the touch screen  190 . 
     The object or item (or a function item) may be at least one of an application, a menu, document, a widget, a picture, video, E-mail, a short message service (SMS) message, and a multimedia messaging service (MMS) message, which have been or can be displayed on the touch screen  190  of the portable device  100 , and the object or item can be created, selected, executed, deleted, canceled, stored, or changed by the user input device. The object or item may be a button, an icon (or a shortcut icon), a thumbnail image, or a folder that stores at least one object in a portable device. Also, the object or item may be displayed in the form of an image, text, etc. The shortcut item is an image that is displayed on the touch screen  190  of the portable device  100  to quickly execute a call, a contact list, a menu, etc., which are basically provided by each application or by the portable device  100 , and if a command or selection for executing the shortcut item is received, the corresponding application is executed. 
     As such, the plurality of executable objects that are displayed on the lock screen according to the embodiment of the present disclosure may include at least one among shortcut icons for executing applications, widgets, icons representing documents with specific file formats, pictures, and folders. 
     For example, the user may himself/herself draw an image, text, etc. to create a unique object or item. The user may set such a personalized object or item as the unique object or item to be linked to a desired application so that only himself/herself can know what application the object or item is linked to. Accordingly, a hidden method of preventing other people from knowing purposes of a personalized object displayed on the lock screen can be implemented to thereby provide a personalized lock screen. 
     Also, the controller  110  may detect a user input event such as a hovering event of making user input means such as a finger approach the touch screen  190  or of locating the user input means close to the touch screen  190 . 
     If a user input event occurs with respect to a predetermined item or according to a predetermined method, the controller  110  may perform predetermined program operation corresponding to the user input event. According to an embodiment, if a request for displaying a lock screen on which a plurality of executable objects are arranged is received, the controller  110  may display content related to a recently occurred event on the lock screen. If the recently occurred event is a missed call, information about the missed call may be displayed on the lock screen, together with a call application related to the missed call. 
     At this time, according to the user&#39;s setting, outline information that is irrelevant to leakage of personal information, for example, a part of a phone number of the other party who made the missed call, may be displayed on the lock screen. If the user takes a gesture of turning the current page to the next page with the input means when the information about the missed call is displayed, the information may be changed to another information. Meanwhile, if the user selects the information about the missed call, the call application may be directly executed to call the other party who made the missed call. As such, according to the present disclosure, the user can easily check an executable object and related information through the lock screen so as to directly execute a desired application. 
     The communication module  120  may include at least one of a mobile communication module, a wireless local area network (WLAN) module, and a short-range communication module. 
     The mobile communication module may enable the portable device  100  to connect to an external device through mobile communication using at least one or a plurality of antennas (not shown), under the control of the controller  110 . The mobile communication module may transmit/receive radio signals for a voice call, a video call, an SMS message, or an MMS message to/from a mobile phone (not shown), a smart phone (not shown), a tablet PC (not shown), or another electronic device (not shown) when the corresponding phone number is input to the portable device  100 . 
     The WLAN module may be connected to the Internet through a WAP, under the control of the controller  110 . The WLAN module  131  may support the IEEE802.11x standard. 
     The short-range communication module may perform short-range communication between the portable device  100  and an external electronic device in a wireless fashion under the control of the controller  110 . The short-range communication may include Bluetooth, infrared data association (IrDA), Wi-Fidirect communication, NFC, and the like. 
     The camera module  150  may include at least one of first and second cameras  151  and  152  for photographing still images or moving images under the control of the controller  110 . The first camera  151  may be disposed in the front side of the portable device  100 , and the second camera  152  may be disposed in the rear side of the portable device  100 . The camera module  150  may function to photograph a user input such as a user gesture for activating the portable device  100 . For example, if the user input means approaches the portable device  100  so that a proximity event is detected, the camera module  150  may be activated to acquire an image. The image may be used to recognize the user gesture, so that predetermined program operation (for example, execution of a predetermined object displayed on the lock screen) may be performed in correspondence to the recognized user gesture. 
     The input/output module  160  may include at least one among at least one button  161 , at least one microphone  162 , at least one speaker  163 , at least one vibration motor  164 , a connector  165 , the keypad  166 , and the earphone connecting jack  167 . However, the input/output module  160  is not limited to the above-mentioned devices, and a cursor control, such as a mouse, a trackball, a joystick, or cursor direction keys, may be provided to control the movement of a cursor on the touch screen  190 . 
     The button  161  may be formed on the front, side, or rear surface of the housing (or case) of the portable device  100 , and may include at least one among a power/lock button, a volume button, a menu button, a home button, a back button, and a search button. For example, if the home button is pressed in a deactivated state in which the screen is off, a user input for activating the screen may be detected so that the lock screen may be displayed. 
     The microphone  162  may receive a voice or sound under the control of the controller  110  to generate an electrical signal. For example, the microphone  162  may receive a user voice for displaying the lock screen. 
     The speaker  163  may output sound corresponding to various signals or data (for example, radio data, broadcasting data, digital audio data, digital video data, etc.) to the outside of the portable device  100 , under the control of the controller  110 . The speaker  163  may output sound (for example, button manipulation sound corresponding to a call, ring back tone, the other party&#39;s voice, etc.) corresponding to a function that is performed by the portable device  100 . There may be provided one or more speakers  163  at one or more appropriate locations on the housing of the portable device  100 . According to an embodiment, the speaker  163  may function to aurally inform information displayed on the lock screen. Accordingly, if a user input for activating the portable device  100  is detected, the off screen may be converted to the lock screen, and then information displayed on the lock screen may be output as sound. 
     For example, if the lock screen has been set to inform weather information, an image and weather information representing a weather condition, such as rainy, cloudy, sunny, and snowy, may be displayed on the lock screen, while outputting a predetermined sound effect corresponding to the weather condition. If the lock screen has been set to display stock information, the upper limit prices, the lower limit prices, etc. may be output as a sound effect. Also, if the lock screen has been set to display sports information, information about wins, ties, and losses of a team which the user cheers for may be output as different sound effects. Also, if the lock screen has been set to display traffic information, information about traffic situations of frequently used roads may be output as a sound effect. As such, according to an embodiment of the present disclosure, by providing various aural effects according to the kind of information displayed on the lock screen, it is possible to provide the user with an intuitive and sensitive UX. 
     The vibration motor  164  may convert an electrical signal into mechanical vibration under the control of the controller  110 . For example, if a voice or video call is made by another device (not shown) when the portable device  100  is in a vibration mode, the vibration motor  164  may operate. There may be provided one or more vibration motors  164  in the housing of the portable device  100 . The vibration motor  164  may operate in correspondence to a user input through the touch screen  190 . According to an embodiment of the present disclosure, various visual effects varying according to the kind of information displayed on the lock screen may be provided with aural effects through the speaker  163 , and also may be provided with tactile effects by differentiating vibration levels through the vibration motor  164 . 
     The connector  165  may be used as an interface for connecting the portable device  100  to an external electronic device or a power source (not shown). The controller  110  may transmit data stored in the storage unit  175  of the portable device  100  to an external electronic device or receive data from the external electronic device through a wired cable connected to the connector  165 .

The storage unit  175  may store applications and control programs for controlling the portable device  100  or the controller  110 . 
     The term “storage unit” indicates an arbitrary data storage device, such as the storage unit  175 , the ROM  112  and RAM  113  in the controller  110 , a memory card (for example, a secure digital (SD) card or a memory stick) installed in the portable device  100 , and the like. The storage unit  175  may include a non-volatile memory, a volatile memory, a hard disk drive (HDD), and a solid state drive (SSD). 
     Also, the storage unit  175  may store applications with various functions, such as navigation, a video call, games, a time-based alarm application, etc., images for providing a user with graphical user interfaces (GUIs) associated with the applications, user information, document, databases or data related to a method of processing touch inputs, background images (a menu screen, a lock screen, etc.) or operation programs required to drive the portable device  100 , images photographed by the camera module  150 , etc. 
     Also, the storage unit  175  may store a plurality of objects that can be used to configure a lock screen, and information that is displayed with respect to the objects. Also, the storage unit  175  may store data created to apply 3 dimensional (3D) graphics effects to the lock screen. The information that is displayed with respect to the objects may be largely classified into primary level information that is irrelevant to leakage of personal information and secondary level information related to personal information. 
     Herein, the primary level information may be information subjected to a process of abstracting or simplifying information to show only a part of the information such that only the owner of the portable device  100  can recognize the information. For example, the primary level information may be a part of a picture in the case of a gallery application, the last digits of a phone number in the case of an address book application, or a message including no information about a sender in the case of a social networking service (SNS) application. In this case, second level information corresponding to the primary level information may be the entire of the picture, all digits of the phone number, or a message including the information about the sender. 
     Like the information classified into the primary and secondary levels, information for executing only a part of the functions of the applications of the objects displayed on the lock screen on the lock screen may be stored. For example, in the case of a calendar application, an empty calendar may be displayed on the lock screen, and if a calendar application execution command is received after the lock screen is released, a screen on which schedule information for details according to date is displayed may be displayed. Also, in the case of a camera application, the storage unit  175  may store data required for outputting a lock screen allowing only photographing. Also, in the case of a memo application, the storage unit  175  may store data required for outputting a lock screen displaying an empty memo instead of a real memo in order to allow a user to draw a new memo. 
     The storage unit  175  is machine (for example, a computer)-readable media, and the term “machine-readable media” can be defined as media of providing data to a machine so that the machine can perform a specific function. The storage unit  175  may include non-volatile media and volatile media. The media should be a tangible device so that commands transferred by the media can be detected by a physical device for reading the commands through a machin. 
     The machine-readable media may include at least one among a floppy disk, a flexible disk, a hard disk, a magnetic tape, a compact disc ROM (CD-ROM), an optical disk, a punch card, a paper tape, a RAM, a programmable ROM (PROM), an erasable PROM (EPROM), and a FLASH-EPROM, however, the machine-readable media is not limited to the above-mentioned devices. 
     The power supply unit  180  may supply power to one or more batteries installed in the housing of the portable device  100  under the control of the controller  110 . The one or more batteries may supply power to the portable device  100 . Also, the power supply unit  180  may supply power received from an external power source to the portable device  100  through a wired cable connected to the connector  165 . Also, the power supply unit  180  may supply power received wirelessly from an external power source to the portable device  100  through wireless charging technology. 
     Also, the portable device  100  may include at least one touch screen  190  that provides a user with GUIs corresponding to various services (for example, a call, data transmission, and photographing. 
     The touch screen  190  may output an analog signal corresponding to at least one user input inputted to a GUI to the touch screen controller  195 . The touch screen  190  may receive at least one user input through a user&#39;s body part (for example, a finger including a thumb) or the input unit (for example, a stylus pen or an electronic pen). Also, the touch screen  190  may sense a touch-and-drag operation. In this case, the touch screen  190  may transfer an analog signal corresponding to a touch trajectory according to the touch-and-drag operation to the touch screen controller  195 . 
     In this specification, the “touch” is not limited to a contact of a finger or the input unit to the touch screen  190 , and may include non-contact recognition (for example, when a user input device is located within a recognition distance (for example, 1 cm) in which the user input device can be detected without a direct contact to the touch screen  190 ). The recognition distance in which the touch screen  190  can recognize the user input device depends on the performance or structure of the portable device  100 . Particularly, in order for the touch screen  190  to distinguish a direct-touch event generated by a direct-contact with a user input device from an indirect-touch event (that is, a hovering event), the touch screen  190  may be configured to output different values (for example, analog values including voltage values and current values) according to the direct-touch event and the hovering event. 
     The touch screen  190  may be a resistive touch screen, a capacitive touch screen, an infrared touch screen, an acoustic wave touch screen, or their combination. 
     The touch screen controller  195  may convert an analog signal received from the touch screen  190  into a digital signal, and transfer the digital signal to the controller  110 . The controller  110  may control the touch screen  190  using the digital signal received from the touch screen controller  195 . For example, the controller  110  may select or execute a shortcut icon or an object displayed on the touch screen  190  in response to a direct-touch event or a hovering event. Also, the touch screen controller  195  may be integrated into the controller  110 . 
     The touch screen controller  195  may detect a value (for example, a current value) output through the touch screen  190  to determine an hovering interval or distance as well as a user&#39;s input location, convert the determined distance value into a digital signal (for example, a z coordinate), and then provide the digital signal to the controller  110 . Also, the controller  110  may detect various user inputs that are received through the camera module  150 , the input/output module  160 , and the sensor module  170 , as well as the touch screen  190 . The user inputs may include various kinds of information that is input to the portable device  100 , such as a user&#39;s gesture, voice, movement of pupil, bio signals, and the like. The controller  110  may control the portable device  100  to perform a predetermined operation or function corresponding to the detected user input. 
       FIG. 2  is a flowchart illustrating an embodiment of a method of providing a lock screen in the portable device  100  according to an embodiment of the present disclosure. Hereinafter, a process of changing a display screen of the portable device  100  will be described in regard of examples shown in  FIGS. 3A to 3D and 4A to 4D , however, the method of providing the lock screen is not limited to these examples. 
     Referring to  FIG. 2 , the controller  110  may determine whether a user input for activating the portable device  100  is detected, in a screen-off state, in operation  300 . 
       FIGS. 3A to 3D  are views for describing a method of changing a display screen of a portable device according to an embodiment of the present disclosure. 
       FIG. 3A  shows an off screen of the portable device  100  that is in a power-on state. In the off-screen state, other user inputs except for a predetermined user input for activating the portable device  100  may be ignored. 
     Referring to  FIG. 3A , a case of making a palm approach a proximity sensor  170   b  in order to activate the portable device  100  is shown, however, a user may input a predetermined command for activating the portable device  100  using any other methods. For example, the user may press one (for example, the home button  161   a ) of the buttons  161  of the input/output module  160 , make a gesture/motion input through the camera module  150  (for example, the first camera  151 ), make a predetermined pattern input (for example, double tap, operation of pinching two fingers together or spreading two fingers apart on the touch screen  190 , operation of drawing a circle on the touch screen  190  with a finger, etc.) on the touch screen  190 , utter a voice command through the microphone  162 , or input a predetermined command for activating the portable device  100  in a wireless fashion through the communication module  120 . 
     If a user input for activating the portable device  100  is detected by one of the above-mentioned methods, the controller  110  may display a lock screen as shown in  FIG. 3B , wherein the lock screen is configured with an area in which a plurality of executable objects are arranged and an information display area in which restricted information related to the objects is displayed, in operation  305 .  FIG. 3B  briefly shows the lock screen, and the lock screen will be described in more detail, later. 
     Referring to  FIG. 3B , the lock screen may have a display area  200  to enable a user to directly check a plurality of applications and basic information related to the applications without releasing the locked state of the portable device  100 . The display area  200  may be configured to allow a user to select one of a plurality of executable objects or to navigate content or images related to the objects. On the lock screen, information to allow a user to directly check a missed call, a new message, a battery charged state, music being currently played, the time and date, etc., a plurality of objects representing a plurality of executable applications, and information related to the objects may be arranged. 
     The plurality of executable objects arranged on the lock screen may represent a plurality of arbitrary applications. The applications may include, for example, an SNS application, a call application, a message application, a schedule management application, a word processing application, a music application, an Internet application, a map application, a camera application, an E-mail application, a picture application, an image editing application, a search application, a file search application, a video application, and a game application. The number and kinds of the objects arranged on the lock screen may be changed according to the user&#39;s settings. For example, objects (icons) of applications that are to be displayed on a lock screen for quick execution may be set or registered in advance by the user&#39;s selection so that the user can create a user-made lock screen. 
     Particularly, on the display area  200 , primary information which is restrictively displayed with respect to a specific object and which is irrelevant to leakage of personal information may be displayed. The primary information may be, for example, processed personal information, such as an English dictionary, public information (for example, an empty schedule list), a part of a phone number, and a part of a picture. Accordingly, when the user wants to check basic information, such as an absence message, the current time, information related to a recently executed application, etc., while at work, the user can easily check such information without releasing the lock screen. 
     After the lock screen is displayed, it may be determined whether a user input for releasing the lock screen is detected, in operation  310 . If a user input for releasing the lock screen is detected, for example, if a user input for converting the lock screen into a home screen is detected, a home screen may be displayed, in operation  315 . For example, if the home button  161   a  is pressed when the lock screen of  FIG. 3B  is displayed, a home screen as shown in  FIG. 3D  may be displayed on the touch screen  190 . Meanwhile, before the home screen is displayed, a lock release screen as shown in  FIG. 3C  may be displayed in order to prevent an unauthenticated person from using the portable device  100 . If no lock function has been set by the user, the lock release screen for receiving a lock release command, as shown in  FIG. 3C , may be not displayed. In the current embodiment, a case in which a lock release screen for receiving a lock release command corresponding to a predetermined pattern is displayed is shown, however, any other method of authenticating a user without displaying any lock release screen, such as face recognition through the camera module  150 , may be applied. 
     Referring to  FIG. 3C , a pattern type lock release screen is shown. In this case, a movement pattern of a touch input is recognized as a lock release command, and whether to release the lock screen is determined according to the lock release command. If the lock screen is released, the home screen as shown in  FIG. 3D  may be displayed. 
     Referring to  FIG. 3D , an example in which a main home screen is displayed on the touch screen  190  is shown. If the portable device  100  has different home screens of several pages, the main home screen may be the first home screen among the home screens of the pages. The home screen may display shortcut icons for executing frequently used applications, a main menu conversion key, a current time, weather information, etc.  FIG. 3D  shows a case in which a home screen is displayed, however, a recently used application may be loaded to display an execution screen. 
     If no user input for releasing the lock screen is detected in operation  310 , the process may proceed to operation  320  to determine whether a user input waiting time is longer than or equal to a predetermined time. If the user input waiting time is longer than or equal to the predetermined time, the controller  110  may deactivate the portable device  100 , in operation  325 . Accordingly, the screen may be again turned off, and other user inputs except for a user input for activation may be ignored. That is, the current screen, for example, the lock screen or the home screen may be maintained until the user input waiting time reaches the predetermined time. 
     The above description relates to a series of processes that are performed until the home screen is displayed after the portable device  100  is activated. Hereinafter, screens that the portable device  100  displays when an object displayed on the lock screen of  FIG. 3B  and content related to the object are selected will be described with reference to  FIGS. 4A to 4D . 
       FIGS. 4A to 4D  are views for describing a method of changing a display screen of a portable device according to an embodiment of the present disclosure. 
       FIG. 4A  shows the deactivated state of the portable device  100 . In this state, if user interaction, such as making user input means for activation approach the portable device  100  or pressing the home button  161   a , is detected, a lock screen having a display area  400 , as shown in  FIG. 4B , may be displayed. On the display area  400 , information that is restrictively displayed with respect to a predetermined object may be displayed. 
     In  FIG. 4B , a case in which a part of available contact information, such as a last call, a missed call, and a bookmark, is displayed is shown. The part of the contact information may be a part of the other party&#39;s phone number or the other party&#39;s face image. Particularly, the other party&#39;s face image may be, for example, a blurred face contour image so that only the owner of the portable device  100  can identify the other party. 
     If a user input for calling the other party is made on the lock screen, a lock release screen as shown in  FIG. 4C  may be displayed. The user input for calling the other party may be, for example, an input of touching the display area  400 . 
     Thereafter, if a predetermined lock release command is received through the lock release screen as shown in  FIG. 4C , the lock screen may be released, and then a screen according to execution of a call application may be displayed, as shown in  FIG. 4D . On the screen according to the execution of the call application as shown in  FIG. 4D , the other party&#39;s original image and all digits of the other party&#39;s phone number may be displayed, instead of the blurred image and the part of the phone number displayed on the lock screen of  FIG. 4B . 
     According to the present disclosure as described above, by arranging a plurality of executable objects on a lock screen, the user can quickly execute a desired application on the lock screen, like on the home screen. Also, by displaying outline information related to the executable objects, together with the executable objects, the user can easily check object-related content recently updated. 
       FIG. 5  is a flowchart detailedly illustrating an embodiment of a method of providing a lock screen in the portable device  100  according to an embodiment of the present disclosure. 
     Referring to  FIG. 5 , operations  500  and  505  are the same as operations  300  and  305  of  FIG. 2 , and accordingly, a detailed description thereof will be omitted. 
       FIG. 6  is a view for describing a configuration of a lock screen according to an embodiment of the present disclosure. 
     Referring to  FIG. 6 , the lock screen may be largely divided into an area  605  in which a plurality of executable objects are arranged, and a restricted information display area  600  on which restricted information related to the objects is displayed. In  FIG. 6 , a case in which the information display area  600  is in the shape of a circle, and the area  605  in which the objects are arranged is in the shape of a ring, like a doughnut, surrounding the information display area  600  in the shape of the circle is shown. However, the information display area  600  may have any other shape, such as an oval shape, a rectangle shape, and a square shape. Also, the objects may be arranged in the shape of a bar, or in the shape of a matrix consisting of rows and columns such that the objects are spaced apart from each other. Also, the objects may be arranged randomly. 
     Also, on the information display area  600 , primary information, such as a part of text and a part of available images, which are irrelevant to personal information, may be displayed. On the area  605  in which the objects are arranged, one or more objects  625 ,  630 , and  635  that are shortcut icons for executing predetermined applications may be arranged. At least some of the objects may be displayed to include at least one of an image and text. The image may be a character or a symbol for representing or easily identifying an application of the corresponding object, or may be text such as logo. The object may include a title to describe a feature of the object, in the form of text for identifying the object. 
     Also, areas  610 ,  615 , and  620  positioned between the objects in the area  605  in which the objects are arranged may be used to represent the states of data related to the corresponding objects. For example, on the areas  610 ,  615 , and  620  positioned between the objects, the amount of data stored for each application, the number of new data, a memory state, etc. may be represented as the states of data by differentiating colors, brightness levels, etc. 
     In the current embodiment, a user input made on the information display area  600  may be considered as an input for changing information that is displayed on the information display area  600 . Also, a user input made on the object  625 ,  630 , or  635  may be considered as an input for executing an application of the corresponding object. 
     Accordingly, when the lock screen is displayed, the controller  110  may determine whether a user input is detected on the information display area  600 , in operation  510 . If the controller  110  determines that a user input, for example, a touch input or a touch-and-drag input is detected on the information display area  600 , the controller  110  may change information displayed on the information display area  600 , in correspondence to the user input, or may output a control signal corresponding to the user input. Operation that is performed when a user input is detected on the information display area  600  will be described with reference to  FIGS. 7A to 7D and 8 , below. 
       FIGS. 7A to 7C  are views for describing a method of changing a display of object information on a lock screen, according to an embodiment of the present disclosure. 
     In  FIG. 7A , a case in which a logo image f for easily identifying an SNS application (for example, Facebook) and an image related to the SNS application are displayed on an information display area of a lock screen is shown.  FIG. 7B  shows a screen appearing when a gesture of touching and dragging the image displayed on the information display area of the lock screen is made. After the touch-and-drag gesture is made, another image as shown in  FIG. 7C  may be displayed. The other image may be preferably an image set to “Open to All” in the SNS application. Likewise, if a user input is detected when text instead of an image is displayed on the information display area, the content of the text may be changed to the content of another text. 
       FIGS. 8 to 13  show configuration examples of lock screens according to various applications, according to various embodiments of the present disclosure. 
     In  FIG. 8 , a case in which an object  800  is displayed as a TV-shaped icon on an area on which objects are arranged, and a remote controller image is displayed on an information display area  805  is shown. Accordingly, a user input made on the information display area  805  may be considered as a control signal corresponding to a remote controller button to be used to control a TV. 
     However, in addition to the above-described configurations, the lock screen may have other various configurations as shown in  FIGS. 9 to 13 . In  FIG. 9 , a case in which a phone-shaped object  900  corresponding to a call application is displayed on an area in which objects are displayed, and outline information related to the call application is displayed on an information display area  905  is shown. In  FIG. 9 , the phone-shaped object  900  may be linked to the call application in order to execute the call application. In  FIG. 10 , a case in which an object  1000  of a title representing chatting of an interactive SNS application is displayed on an area in which objects are displayed, and the content of the chatting is displayed on an information display area  1005  is shown. In  FIG. 11 , a case in which a memo-shaped object  1100  linked to a memo application is displayed on an area in which objects are displayed, and a memo window is displayed on an information display area  1105  is shown. In  FIG. 12 , a case in which a calendar-shaped object  1200  is displayed on an area in which objects are displayed, and a calendar is displayed on an information display area  1205  is shown. In  FIG. 13 , a case in which an object  1300  representing a music application is displayed on an area in which objects are displayed, and music-related buttons and music-related content are displayed on an information display area  1305  is shown. 
     Meanwhile, content that is displayed on the information display area may be changed by a predetermined method which will be described with reference to  FIGS. 14A and 14B to 15 , below. 
       FIGS. 14A and 14B  show examples of screens for describing an interaction method for outputting a lock screen in a screen-off state, according to an embodiment of the present disclosure. 
     For example, referring to  FIG. 14A , if a user input for activation is detected after a deactivation screen  1400  of the portable device  100  is displayed, a lock screen  1410  may be displayed. Then, if another user input for activation is detected after a deactivation screen  1420  is displayed, a lock screen  1430  of new content may be displayed, as shown in  FIG. 14B . As such, whenever user interaction occurs, information that is displayed on a lock screen may change. The information may be frequently changing data, such as, for example, weather, a picture, and stocks. 
       FIG. 15  shows examples of screens for describing an interaction method for outputting a lock screen in a screen-off state, according to an embodiment of the present disclosure. 
     In  FIG. 15 , a case in which information  1510  is displayed to correspond to an area  1500  touched by a user is shown. In this case, the user can see information of his/her desired size. 
     Meanwhile, if no user input is detected on the information display area in operation  510 , or if information displayed on the information display area changes or a control signal is output in operation  515 , the controller  110  may determine whether a command for executing an object located on the area in which the objects are arranged is received, in operation  520 . 
     In order to execute an application related to an object, the user may use, as shown in  FIG. 6 , user input means such as a finger or a stylus pen to touch an object A for a predetermined time and then drag the object A to the location of the next object, object B, in a clockwise direction ( 645 ). Alternatively, the user may perform operation of dragging his/her finger outward from the center of the circle area until the finger gets out of the area in which the objects are arranged ( 640 ). In this case, an application corresponding to an object that is in an activated state may be executed. The object that is in the activated state may be an object displayed in a selectable state when a user input is generated by user input means. In the current embodiment, a touch-and-drag operation has been described as an example of an object execution command, however, other various methods such as touching an object for a predetermined time or more may be applied. 
     If an object execution command as described above is received, it may be determined whether the lock function has been set, in operation  525 . If it is determined that the lock function has been set, a lock release screen may be displayed in operation  530 , and then it may be determined whether a lock release command is received, in operation  535 . If a lock release command is received, an execution screen of an application corresponding to the object may be displayed, together with detail information about the object, in operation  540 . Meanwhile, if it is determined in operation  525  that no lock function has been set, operations  530  and  535  may be omitted. Operations  545  and  550  are the same as operations  320  and  325  of  FIG. 2  as described above, and accordingly, a detailed description thereof will be omitted.
