BACKGROUND
Field
The disclosure relates to a method and mobile communication terminal for performing a specific function when a mobile communication terminal is activated, and more particularly to a method and mobile communication terminal for performing various functions according to the number of presses or a press time of a button for switching from an inactive state to an active state.
Description of the Related Art
Recently, various terminals, for example, such as smart phones, mobile phones, personal digital assistants (PDAs), and web pads, having not only communication functions but also various other functions have come into wide use. These terminals have rapidly been generalized because not only can an environment identical or similar to a desktop computer be implemented anytime and anywhere on the above-described terminals, but they also include a telephone function.
At present, in order to operate a corresponding function among various functions included in a terminal such as those described above, a certain operation should be performed in a state in which the terminal is in an active state, that is, in a state in which a display is turned on. In addition, in order to add a certain function, an interface or button for performing the function should be added to the terminal. For example, it is possible to transmit a rescue signal indicating an emergency or urgent situation by pressing an emergency button only when the emergency button for the urgent situation is separately added.
On the other hand, users of the terminals described above perform operations of habitually taking out and activating the terminals on the move or in a standby state while carrying the terminals.

TERMS
The term “mobile communication terminal” used herein refers to a digital device that includes a memory means and a microprocessor with computing capability as in a mobile phone, a navigation system, a web pad, a PDA, a workstation, a personal computer (for example, a notebook computer or the like) as a digital device including wired/wireless communication functions or other functions. Although an example of the mobile communication terminal (for example, a mobile phone) will be described in part of this specification, the present invention is not limited thereto.
The term “inactive state” used herein refers to a state in which the mobile communication terminal is communicable but a display screen is turned off. Even when the display screen is turned off, a predetermined function (for example, a music play function or the like) is operable. As described above, the term “inactive state” used herein refers to a concept encompassing states in which the display screen is turned off, regardless of whether or not the mobile communication terminal performs a predetermined operation. However, a state in which the mobile communication terminal is completely turned off is excluded.
The term “active state” used herein refers to a state in which the display screen of the mobile communication terminal is turned on. Switching from the “inactive state” to the “active state” refers to switching of the display screen from the OFF state to the ON state, regardless of information displayed on the display screen in the ON state. For example, the mobile communication terminal can be determined to be in the “active state” even when only a lock screen is displayed.
Mobile Communication Terminal
FIG. 1 is a diagram illustrating an external appearance of the mobile communication terminal according to an embodiment of the present invention.
Referring to FIG. 1, the mobile communication terminal 100 according to this embodiment can include a display unit 110 and an activation button 120. The mobile communication terminal 100 can further include a camera 130.
Although the display unit 110 is provided on the front side of a frame constituting the mobile communication terminal 100, the activation button 120 is provided on a lower part of the display unit 110, and the camera 130 is provided on an upper part of the display unit 110 as illustrated in FIG. 1, other forms may be configured. For example, the display unit 110 need not necessarily be formed on the entire surface of the mobile communication terminal 100. That is, the display unit 110 is only required to be formed on at least part of the mobile communication terminal 100, and the activation button 120 is only required to be formed on a part different from that of the display unit 110. In addition, the camera 130 can be formed on the other side on which the display unit 110 is not provided in the mobile communication terminal 100.
The display unit 110 displays various information regarding operation states of the mobile communication terminal 100, and also displays an interface for a user's input if the mobile communication terminal 100 drives a touch screen. In general, if a state in which the user's operation on the mobile communication terminal 100 is absent continues for a predetermined period of time, the mobile communication terminal 100 is in the inactive state. The user's operation refers to an input through the interface displayed on the display unit 110, an operation through the button 120, or an operation through a function key (for example, a volume control key or the like). A condition in which the inactive state is reached can be set by the user. For example, the condition can be set using a setting menu through the interface displayed on the display unit 110. On the other hand, the state can be switched to the inactive state by pressing another button (for example, an ON/OFF button) provided on the mobile communication terminal 100. For example, the mobile communication terminal 100 can be completely turned off if the ON/OFF button is pressed for a long time when the mobile communication terminal 100 is in the active state, but the mobile communication terminal 100 can be in the inactive state as a communicable state in which a phone call can be received if the ON/OFF button is pressed for a short time.
The activation button 120 is means for switching the mobile communication terminal 100 from the inactive state to the active state. That is, if the user presses the activation button 120 when the mobile communication terminal 100 is in the inactive state, switching to the active state is performed. FIG. 1 illustrates a state in which a lock screen is displayed on the display unit 110 after pressing the activation button 120 when the mobile communication terminal 100 is in the inactive state. However, the activation button 120 can function as means for another operation (for example, means for moving to a standby screen while a certain operation state is displayed on the display unit 110 or means for displaying a list of programs currently being operated).
According to an embodiment of the present invention, if the user presses the activation button 120 when the mobile communication terminal 100 is in the inactive state, the mobile communication terminal 100 performs a predetermined operation in addition to switching to the active state. For example, image information is displayed on a lock screen of the display unit 110 when the predetermined operation is being performed. The image information is displayed on a lock screen of the display unit when the predetermined operation is being performed. The lock screen is configured to be displayed when the mobile communication terminal 100 changes from the inactive state to the active state. The display unit 110 can provide an unlock means on a part of the display unit 110 when the predetermined operation is being performed.
When the mobile communication terminal 100 is in the inactive state, the user can set an operation to be performed by pressing the activation button 120. For example, an operation of the mobile communication terminal 100 connected to the activation button 120 can be set using a setting menu through the interface displayed on the display unit 110. In addition, according to an embodiment of the present invention, an operation which differs according to the number of presses or a press time of the activation button 120 can be performed when the mobile communication terminal 100 is in the inactive state. For example, a first operation can be set to be performed if the activation button 120 is pressed once, and a second operation can be set to be performed if the activation button 120 is continuously pressed three times. In addition, as another example, the first operation can be set to be performed if the activation button 120 is pressed once for a short time, and the second operation can be set to be performed if the activation button 120 is pressed once for a long time. The mobile communication terminal 120 can include a predetermined clock circuit or timer to calculate the cumulative number of continuous presses of the activation button 120 and measure a period of time for which the activation button 120 is pressed. For example, the number of presses is determined to be two if the activation button 120 is re-pressed within a threshold time after one press. If the activation button 120 is pressed for the threshold time or more, a long press of the activation button 120 can be determined. Operations capable of being performed by pressing the activation button 120 in the inactive state will be described later.
According to an embodiment of the present invention, a sub-display unit 121 can be provided on the activation button 120. Information regarding an operation to be performed by pressing the activation button 120 can be displayed on the sub-display unit 121. Various types such as a shape, a character, a graphic, and color can be displayed. When the display type is the shape, a circle, a triangle, a rectangle, a hexagon, or the like can be displayed. For example, the circle can be displayed on the sub-display unit 121 when the first operation is set to be performed by pressing the activation button 120, and the triangle can be displayed on the sub-display unit 121 when the second operation is set to be performed by pressing the activation button 120, and vice versa. A display type of the sub-display unit 121 and a correspondence relationship between operations and displays can also be set by the user. For example, the user can select the first operation as the operation to be performed by pressing the activation button 120 from a setting menu and select the triangle as the display type of the sub-display unit 121 of the activation button 120. Accordingly, the user can recognize that the first operation is performed when the user has pressed the activation button 120 because the triangle is displayed on the sub-display unit 121 even when the mobile communication terminal 100 is in the inactive state.
Although the sub-display unit 121 can be implemented by a general display such as liquid crystal, a liquid crystal display (LCD), or a light emitting diode (LED), the present invention is not limited thereto.
An operation of controlling driving of the display unit 110 and the sub-display unit 121 can be performed in the same processor and the same method or in different processors and different methods.
Hereinafter, various embodiments for operations of the mobile communication terminal 100 capable of being performed by pressing the activation button 120 will be described.
Operations Through Activation Button
Operations to be described below can be performed by pressing the activation button 120 when the mobile communication terminal 100 is in the inactive state, and set by the user. The operations described below are only examples. Of course, other operations can be performed by pressing the activation button 120.
1. Camera Activation Function
When the mobile communication terminal 100 is in the inactive state, the camera 130 provided in the mobile communication terminal 100 can be activated by pressing the activation button 120, and a screen currently imaged by the camera 130 can be displayed on the display unit 110.
FIG. 2 is a diagram illustrating an example in which the camera 130 is activated after the activation button 120 is pressed and an imaged scene is displayed on the display unit 110.
2. Health Sensing and Health Information Transmission Functions
When the mobile communication terminal 100 is in the inactive state, the health sensing function can be driven, so that sensed health information can be transmitted to a medical authority such as a doctor or a protector.
FIGS. 3A and 3B are block diagrams of the mobile communication terminal 100 illustrating the above-described functions. FIGS. 3A and 3B illustrate functional block diagrams illustrating the above-described functions of the mobile communication terminal 100.
Referring to FIG. 3A, the mobile communication terminal 100 can include an activation sensing unit 310, a health sensing unit 320, and a health information transmission unit 330.
When the mobile communication terminal 100 is in the inactive state, the activation sensing unit 310 senses whether or not the user has pressed the activation button 120.
The health sensing unit 320 is operated when the activation sensing unit 310 has sensed that the activation button 120 has been pressed, and senses a health state of the user in various methods.
FIG. 3B is a block diagram illustrating an example of the health sensing unit 320. Referring to FIG. 3B, the health sensing unit 320 can include a camera activation element 321, an eyeball detection element 322, and a health information acquisition element 323.
The camera activation element 321 activates the camera 130 provided in the mobile communication terminal 100. According to the activation of the camera 130, a video currently captured by the camera 130 is displayed on the display unit 110. If an eye or face of the user is imaged by the camera 130, the eyeball detection element 322 performs a function of recognizing and extracting an eyeball of the user. A general eyeball detection algorithm can be used for eyeball detection. The health information acquisition element 323 acquires various health information through the eyeball detected through the eyeball detection element 322. It is possible to recognize a stress index, a diabetes index, or retinal diseases of the user through a color or health state of the eyeball. A well-known algorithm in the related art can be used as an algorithm for detecting health information from characteristics of the detected eyeball.
The health information acquired as described above can be transmitted by the health information transmission unit 330 to the mobile communication terminal of a protector, a medical authority such as a doctor or the like, or a predetermined server. Information regarding the protector (for example, a phone number or an e-mail address) can be stored in advance. The acquired health information can be displayed on the display unit 110 so that the user can check the acquired health information.
The above-described operations, that is, the eyeball detection function and the health sensing function based on information regarding the detected eyeball, can be performed by installing a predetermined application. That is, the application includes an eyeball detection algorithm and a health sensing algorithm, so that the operations as described above can be performed by installing the application in the mobile communication terminal 100. The user can download this application and install the downloaded application in the mobile communication terminal 100. In addition, although an example of only health sensing through eyeball detection has been described above, it is possible to install an application, for example, for health sensing through face detection, and connect the application to the activation button 120. The user can use the functions as described above by setting the application to be operated immediately when the activation button 120 is pressed through the setting menu in the inactive state of the mobile communication terminal 100.
In general, aged persons may not use the health sensing function due to a difficult operation even when the health sensing function is provided in the mobile communication terminal 100. However, according to the above-described embodiment of the present invention, the health sensing function is operated only by pressing the activation button 120 without a special operation. Accordingly, it is possible to easily check health information and transmit the health information to a protector or a doctor.
3. User Identification Function
When the mobile communication terminal 100 is in the inactive state, a user authentication process can be performed for security by pressing the activation button 120.
FIGS. 4A and 4B illustrate block diagrams of the mobile communication terminal 100 illustrating the above-described functions. Referring to FIG. 4A, the mobile communication terminal 100 can include an activation sensing unit 410 and a user identification unit 420.
When the mobile communication terminal 100 is in the inactive state, the activation sensing unit 410 senses whether or not the user has pressed the activation button 120.
If the activation sensing unit 410 senses that the activation button 120 has been pressed, the user identification unit 420 operates the user identification function in various methods.
FIG. 4B is a block diagram illustrating an example of the user identification unit 420. Referring to FIG. 4B, the user identification unit 420 can include a camera activation element 421, an iris detection element 422, and a user identification element 423.
The camera activation element 421 activates the camera 130 provided in the mobile communication terminal 100. According to the activation of the camera 130, a video currently captured by the camera 130 is displayed on the display unit 110. If an eye or face of the user is imaged by the camera 130, the iris detection element 422 performs a function of recognizing and extracting an iris from an eyeball of the user. A general iris detection algorithm can be used for iris recognition. The user identification element 423 performs a function of comparing the iris detected by the iris detection element 422 to pre-stored iris information of the user, and authenticating the current user as a true user if the two match. For this, the user identification element 423 can use iris information of the user pre-stored in a database (not illustrated). The iris information of the user can be stored by registering information regarding the iris detected by the iris detection element 422 using a video of the true user first captured by the camera 130. Predetermined identification information (for example, an identifier (ID), a password, a social security number, or the like) should be input to change the registered iris information of the true user. If the user identification element 423 authenticates the current user as the true user, the lock state of the mobile communication terminal 100 is released and all functions are available. If the current user is not authenticated as the true user, the lock state continues along with a display of an alarm message.
The above-described operations, that is, the iris detection function, the user identification function, and the user authentication function, can be performed by installing a predetermined application. That is, the application includes the iris detection algorithm and the authentication algorithm based on an iris comparison, so that the operations as described above can be performed by installing the application in the mobile communication terminal 100. The user can download this application and install the downloaded application in the mobile communication terminal 100. The user can use the functions as described above by setting the application to be operated immediately when the activation button 120 is pressed through the setting menu in the inactive state of the mobile communication terminal 100.
Accordingly, it is possible to efficiently reduce security risks by setting the user authentication process to be performed through a separate setting, that is, by pressing the activation button 120, when the mobile communication terminal 100 is used in a region vulnerable to the security risks.
Although an example of an authentication method through iris recognition has been described above, other authentication methods, for example, an authentication key matching method, a password matching method, a face recognition method, a fingerprint recognition method, and the like, can be used. That is, one or more authentication methods can be performed by pressing the activation button 120.
4. Location Information Transmission Function
When the mobile communication terminal 100 is in the inactive state, collected location information can be transmitted to a protector or a protection authority (a police station or a fire station) by pressing the activation button 120.
FIG. 5 illustrates a block diagram of the mobile communication terminal 100 illustrating the above-described function. Referring to FIG. 5, the mobile communication terminal 100 can include an activation sensing unit 510, a location information collection unit 520, and a location information transmission unit 530.
When the mobile communication terminal 100 is in the inactive state, the activation sensing unit 510 senses whether or not the user has pressed the activation button 120.
When the activation sensing unit 510 senses that the activation button 120 has been pressed, the location information collection unit 520 collects a current location using a global positioning system (GPS) sensor or other location sensors.
The location information transmission unit 530 performs a function of transmitting location information collected by the location information collection unit 520 to a protector or a protection authority. In an urgent situation, a message indicating the urgent situation can be transmitted along with the location information. The location information and the urgent message can be optionally transmitted. On the other hand, this operation may differ according to the number of presses or a press time of the activation button 120. For example, it is possible to set an operation of transmitting the urgent message to a police station along with the location information when the activation button 120 is pressed for a short time, and set an operation of transmitting only the location information to the protector when the activation button 120 is pressed for a long time. In addition, as another example, it is possible to set an operation of transmitting the location information to the police station along with the urgent message when the activation button 120 is pressed once and set an operation of transmitting the location information to a fire station along with the urgent message when the activation button 120 is pressed three times.
The above-described operations can be performed by installing a predetermined application. That is, the application includes an algorithm for collecting location information and transmitting the collected located information along with an urgent message, so that the operations as described above can be performed by installing the application in the mobile communication terminal 100. The user can download this application and install the downloaded application in the mobile communication terminal 100. The user can use the functions as described above by setting the application to be operated immediately when the activation button 120 is pressed through the setting menu in the inactive state of the mobile communication terminal 100.
Accordingly, it is possible to efficiently escape a dangerous situation because the user can report the dangerous situation to a protector or a protection authority along with his/her location information with only a simple operation.
5. File Transmission Function
When the mobile communication terminal 100 is in the inactive state, a function of uploading content (for example, contact information, a photo, a moving image, or an application) included in the mobile communication terminal 100 to another mobile communication terminal 100 or a media space (for example, a personal media space such as Twitter, Facebook, or a blog or a community media space such as a café or club community) can be operated.
6. Mode Change During Drive
When the mobile communication terminal 100 is in the inactive state, the mobile communication terminal 100 can be switched to a hands-free function or some communication functions (a voice communication function, a short message service (SMS) function, and an Internet function) of the mobile communication terminal 100 can be interrupted by pressing the activation button 120.
Accordingly, it is possible to significantly reduce traffic accident risks by switching the mode of the mobile communication terminal 100 or interrupting the communication function with only a simple operation of pressing the activation button 120 during driving.
7. Advertisement Display Operation
When the mobile communication terminal 100 is in the inactive state, the activation button 120 is pressed so that an advertisement can be displayed on at least a part of the display unit 110. The advertisement display can be implemented by displaying an advertisement provided from an external server in real time, and driven by an advertisement-related application previously installed within the mobile communication terminal 100.
This application for enabling the advertisement to be displayed may be received in advance from an advertisement distribution server, an advertiser server, or a server for providing a service according to an embodiment of the present invention, that is, a service for driving a predetermined application according to a button input that switches the mobile communication terminal 100 from the inactive state to the active state.
An advertisement display method can be implemented by a method of randomly displaying advertisements of advertisers joining this service, a customized advertisement display method based on user information, and an advertisement display method based on a current location.
The user information can be pre-stored in a corresponding application and pre-transmitted to a server that provides an advertising service. On the other hand, location information collection necessary for the advertisement display method based on the current location can be used in conjunction with 4. Location Information Function described above. That is, current location information is collected simultaneously with the activation of the mobile communication terminal 100 and transmitted to an advertising-service providing server. Based on the current location information, advertisements related to the current location are distributed to the mobile communication terminal 100.
8. Other Application Operations
If a predetermined operation is performed in addition to switching to a simple active state by pressing the activation button 120 when the mobile communication terminal 100 is in the inactive state, this belongs to the scope of the present invention.
For example, an entertainment operation (for example, an operation of a music or video player, execution of a game application, or news reception) can be performed by pressing the activation button 120.
Operation Standby of Application
According to an embodiment of the present invention, the above-described predetermined applications are driven when the mobile communication terminal 100 is switched from the inactive state to the active state.
For this, when the mobile communication terminal 100 is in the inactive state, the applications should be maintained in an operation standby state. When the mobile communication terminal 100 is switched from the active state to the inactive state, the above-described applications can be in the operation standby state. That is, a selected application to be driven when the mobile communication terminal 100 is switched to the active state can be in the operation standby state when the mobile communication terminal 100 is switched to the inactive state.
However, a predetermined application operable when the mobile communication terminal 100 is switched from the inactive state to the active state regardless of the operation standby state or an operation disable state of the application belongs to the present invention.
Service Providing Server
Hereinafter, the service providing server according to an embodiment will be described.
FIG. 6 is a diagram illustrating a configuration of a service providing system (server) for enabling a specific function to be operated when the mobile communication terminal is activated according to an embodiment of the present invention.
Referring to FIG. 6, the service providing server 200 can include an application providing unit 210, an activation sensing unit 220, an application driving unit 230, a communication unit 240, and a control unit 250. According to an embodiment of the present invention, the application providing unit 210, the activation sensing unit 220, the application driving unit 230, the communication unit 240, and the control unit 250 of the service providing server 200 can be program modules or hardware communicable with an external apparatus. The program modules or hardware can be included in the service providing server 200 or another apparatus communicable with the service providing server 200 in the form of an operation system, an application program module, and other program modules, and physically stored in various known storage apparatuses. On the other hand, these program modules or hardware include a routine, a sub routine, a program, an object, a component, and a data structure, each of which executes a specific task to be described later or specific abstract data, but the present invention is not limited thereto.
The application providing unit 210 enables the predetermined application described above to be transmitted to the mobile communication terminal 100. The user can receive a desired application by accessing the service providing server 200 through the mobile communication terminal 100, and install the received application within the mobile communication terminal 100. The application can include a control function of controlling a predetermined operation to be performed when the mobile communication terminal 100 is activated, and can independently perform the predetermined operation. For example, the application transmitted from the application providing unit 210 can be an application for enabling an advertisement to be displayed on the display unit 110 when the mobile communication terminal 100 is switched from the inactive state to the active state.
The activation sensing unit 220 according to an embodiment can sense the switching of the mobile communication terminal 100 from the inactive state to the active state. The user can transmit a signal indicating the activation of the mobile communication terminal 100 to the service providing server 200 by pressing the activation button of the mobile communication terminal 100.
The application driving unit 230 according to an embodiment enables a predetermined operation to be performed in the mobile communication terminal 100 when the activation of the mobile communication terminal 100 is sensed. That is, the application driving unit 230 drives a predetermined application within the mobile communication terminal 100 and enables a related screen to be displayed on the display unit 110. For example, if the activation of the mobile communication terminal 100 is sensed, an advertisement-related application can be executed. The application driving unit 230 can perform an additional operation related to driving of a corresponding application. For example, an application for enabling an advertisement to be displayed is driven to receive current location information and control advertisement information related to a corresponding location to be displayed on the display unit 110 of the mobile communication terminal 100. In addition, it is possible to collect user information (for example, a sex, an age, a region of residence, a matter of interest, and the like) and control advertisement information customized for a corresponding user to be displayed. Necessary advertisement information (for example, advertisement information to be transmitted to the mobile communication terminal 100 based on location information or user information) can be transmitted from an advertiser server or an advertisement distribution server. As described above, the application driving unit 230 can drive a predetermined application simultaneously with the activation within the mobile communication terminal 100 and perform an additional operation for optimally driving the application.
The communication unit 240 according to an embodiment makes information communication between the service providing server 200, the mobile communication terminal 100, and another apparatus possible.
