`ACTIVATING DISPLAY AND PERFORMING
`USER AUTHENTICATION IN MOBILE
`TERMINAL WITH ONE-TIME USER INPUT
`
`INCORPORATION BY REFERENCE TO ANY
`PRIORITY APPLICATIONS
`
`Any and all applications for which a foreign or domestic
`priority claim is identified in the Application Data Sheet as
`filed with the present application are hereby incorporated by
`reference under 37 CFR 1.57.
`
`BACKGROUND
`
`Field
`The disclosure relates to a method and mobile commu-
`
`nication terminal for performing a specific function when a
`mobile communication terminal is activated, and more par-
`ticularly 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 com-
`puter be implemented anytime and anywhere on the above-
`described terminals, but they also include a telephone func-
`tion.
`
`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 perform-
`ing 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.
`
`SUMMARY
`
`According to an embodiment, there is provided a mobile
`communication terminal comprising: a display unit includ-
`ing a touch screen capable of receiving user’s input through
`the touch screen for controlling the mobile communication
`terminal; a memory unit; a communication unit; and an
`activation sensing unit, wherein the activation sensing unit
`detects a change from an inactive state of the mobile
`communication terminal to an active state of the mobile
`communication terminal, wherein the inactive state is
`defined that the display unit being turned off while the
`mobile communication terminal being communicable and
`the active state is defined that the display unit being turned
`on while the mobile communication terminal being com-
`municable, wherein the mobile communication terminal
`performs a predetermined operation by an application of the
`
`2
`
`mobile communication terminal when the activation sensing
`unit detects the change from the inactive state to the active
`state.
`
`According to an another embodiment, there is provided a
`method for performing a specific function when a mobile
`communication terminal is activated, the method compris-
`ing: sensing a change from an inactive state of the mobile
`communication terminal to an active state of the mobile
`communication terminal, wherein the inactive state is
`defined that a display unit being turned off while the mobile
`communication terminal being communicable, wherein the
`active state is defined that a display unit being turned on
`while the mobile communication terminal being communi-
`cable; and performing a predetermined operation by an
`application of the mobile communication terminal when the
`mobile communication terminal changes from the inactive
`state to the active state.

`
`Hereinafter, embodiments of the present invention will be
`explained in detail with reference to the accompanying 5
`drawing so that those skilled in the art can easily practice the
`invention.
`
`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 worksta-
`tion, a personal computer (for example, a notebook com-
`puter 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
`
`10
`
`15
`
`20
`
`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 25
`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 commu-
`nication terminal performs a predetermined operation. How-
`ever, a state in which the mobile communication terminal is 30
`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 35
`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 deter-
`mined 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 embodi-
`ment of the present invention.
`Referring to FIG. 1, the mobile communication terminal 45
`100 according to this embodiment can include a display unit
`110 and an activation button 120. The mobile communica-
`tion 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 50
`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 55
`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 activa-
`tion button 120 is only required to be formed on a part
`different from that of the display unit 110. In addition, the 60
`camera 130 can be formed on the other side on which the
`
`display unit 110 is not provided in the mobile communica-
`tion terminal 100.
`
`The display unit 110 displays various information regard-
`ing 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.
`
`65
`
`4
`
`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 per-
`formed. FIG. 1 illustrates a state in which a lock screen is
`
`displayed on the display unit 110 after pressing the activa-
`tion 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 predeter-
`mined 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 con-
`nected 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 num-
`ber 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
`

`
`5
`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 activa-
`tion 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 per-
`formed by pressing the activation button 120 can be dis-
`played 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 opera-
`tions 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. Accord-
`ingly,
`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 per-
`formed 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 com-
`munication 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 com-
`munication 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
`
`5
`
`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-de-
`scribed 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 activa-
`tion 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 infor-
`mation 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 ele-
`ment 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. Awell-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 prede-
`termined 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 detec-
`tion function and the health sensing function based on
`information regarding the detected eyeball, can be per-
`formed 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 appli-
`cation 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 per-
`formed for secur
