`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`1. Field
`The disclosure relates to a method, a system, and a mobile
`communication terminal for performing a specific function
`when a mobile communication terminal is activated, and
`more particularly to a method, a system, and a mobile com(cid:173)
`munication 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.
`2. 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 30
`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 35
`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 40
`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 sepa(cid:173)
`rately added.
`On the other hand, users of the terminals described above 45
`perform operations of habitually taking out and activating the
`terminals on the move or in a standby state while carrying the
`terminals.
`
`Exemplary embodiments are described in further detail
`below with reference to the accompanying drawings. It
`should be understood that various aspects of the drawings
`may have been exaggerated for clarity:

`tion will be explained in detail with reference to the accom(cid:173)
`panying drawing so that those skilled in the art can easily
`practice the invention.
`[Exemplary Embodiments of Present Invention]
`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 commu(cid:173)
`nication 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 ter- 35
`minal 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 40
`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.
`Configuration of Mobile Communication Terminal
`FIG. 1 is a diagram illustrating an external appearance of
`the mobile communication terminal according to an exem(cid:173)
`plary embodiment of the present invention.
`Referring to FIG. 1, the mobile communication terminal
`100 according to this exemplary 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 65
`only required to be formed on a part different from that of the
`display unit 110. In addition, the camera 130 can be formed
`
`4
`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 regard(cid:173)
`ing operation states of the mobile communication terminal
`5 100, and also displays an interface for a user's input if the
`mo bile 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 prede(cid:173)
`termined period of time, the mobile communication terminal
`10 100 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
`15 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.
`20 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
`25 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
`30 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 inac-
`tive 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 exemplary 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 instead of switching to the active
`45 state. 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
`50 the interface displayed on the display unit 110. In addition,
`according to an exemplary embodiment of the present inven(cid:173)
`tion, 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
`55 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
`60 be performed if the activation button 120 is pressed once for
`a short time, and the second operation can be set to be per(cid:173)
`formed 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 cumula(cid:173)
`tive 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 deter-
`
`IPR2019-00611 Page 00008
`
`

`

`US 8,831,557 B2
`
`5
`mined 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 5
`120 in the inactive state will be described later.
`According to an exemplary 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 10
`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 15
`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 corre- 20
`spondence 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 25
`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 communica(cid:173)
`tion 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 dis(cid:173)
`play (LCD), or a light emitting diode (LED), the present
`invention is not limited thereto.
`An operation of controlling driving of the display unit 110 35
`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 exemplary embodiments for opera(cid:173)
`tions 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 commu(cid:173)
`nication 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(cid:173)
`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 60
`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 com(cid:173)
`munication terminal 100 illustrating the above-described

`grams 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 sens(cid:173)
`ing 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 cur(cid:173)
`rently 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
`30 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 characteris-
`tics 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
`40 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-
`45 tion function and the health sensing function based on infor(cid:173)
`mation regarding the detected eyeball, can be performed by
`installing a predetermined application. That is, the applica(cid:173)
`tion includes an eyeball detection algorithm and a health
`sensing algorithm, so that the operations as described above
`50 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
`mo bile communication terminal 100. In addition, although an
`example of only health sensing through eyeball detection has
`55 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 appli-
`cation 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
`65 terminal 100. However, according to the above-described
`exemplary embodiment of the present invention, the health
`sensing function is operated only by pressing the activation
