Hereinafter, embodiments of the present invention will be described.

Embodiments disclosed in this document can be implemented in the electronic device 100 described with reference to Fig.

In the present invention, the display module 151 is assumed to be the touch screen 151 for convenience of explanation. As described above, the touch screen 151 can perform both the information display function and the information input function. However, it should be clearly understood that the present invention is not limited thereto. Also, the touch mentioned in this document can include both touch and proximity touch. In addition, the tapping referred to in this document refers to a touch gesture such as a click of a mouse on a general computer, which is an operation in which the touch screen 151 is lightly pressed and released once.

Hereinafter, a control method of the electronic device 100 according to an embodiment of the present invention and an operation of the electronic device 100 performing the method will be described in detail with reference to the necessary drawings.

2 is a flowchart illustrating a control method of the electronic device 100 according to an embodiment of the present invention. 3 to 8 are views for explaining a control method of the electronic device 100 according to an embodiment of the present invention.

Referring to FIG. 2, when the controller 180 is requested to enter a lock screen state (S101), the controller 180 enters a lock screen state. In addition, as the user enters the lock screen state, the first object having the liquid attribute and dynamically changing is displayed on the touch screen 151 (S102). The lock screen function is a function for preventing a malfunction of the electronic device 100 due to an unintended touch input on the touch screen 151. The control unit 180 enters a lock screen state when a lock screen state entry is requested through the user input unit 130 or when there is no control input received over a predetermined time.

The first object can be dynamically changed in the display area in conjunction with the lock screen state. Also, the first object may be subject to dynamic movement or changes in its surface or interior. For example, when the first object is touched while the first object is displayed on the touch screen 51, the controller 180 may display a wavelength on the first object.

FIG. 3 shows an example of entry into the lock screen state.

3, the control unit 180 displays the first object 3a having the liquid attribute on the touch screen 151 when the lock screen state is requested to be entered. Also, the display area of the first object 3a is gradually increased (S201). When the first object 3a is displayed on the entire area of the screen of the electronic device 100, the lock screen state is entered (S202). The display area of the first object 3a gradually increases and the first object 3a of the electronic device 100 is changed to cover the entire screen in the lock screen state.

In addition, the first object may have a transparent property such as water. If the first object has a transparent property, the user can view the execution screen that was displayed before the first object is displayed through the first object.

FIG. 4 illustrates an example of displaying a lock screen state when the first object has transparency.

Referring to FIG. 4, the controller 180 receives a lock screen state entry request while displaying the menu screen 4a (S301). Upon entering the lock screen state, the control unit 180 displays the first object 3a having the liquid attribute on the touch screen 151 (S302). Meanwhile, since the first object 3a has transparency, even if the first object 3a is displayed on the entire screen, the user can view the previously displayed menu screen 4a through the first object 3a .

As described above, when the first object 3a has transparency, it is possible for the user to confirm the information about the work performed before entering the lock screen state even if the user does not release the lock screen state.

Referring again to FIG. 2, when the touch screen 151 is touched (S103) in the lock screen state, the controller 180 displays dynamic movement on the surface of the first object based on the touched point (S104).

For example, the control unit 180 may display a wavelength dynamically moving to the first object based on a point to be touched. Also, for example, the controller 180 may display a wave that dynamically moves to the first object based on the drag path as the touch screen 151 is dragged.

FIG. 5 shows an example of a case where the touch screen 151 is touched in a lock screen state.

Referring to FIG. 5, when the controller 180 enters the lock screen state, the controller 180 displays the first object 3a having the liquid property on the entire screen. When the specific point 5a of the touch screen 151 is touched while the first object of the liquid property is displayed, the controller 180 stores the wavelength 5b spreading around the touched point 5a as the first object 3a ).

2, when a specific event such as message reception or e-mail reception occurs in the lock screen state (S105), the control unit 180 displays the second object corresponding to the generated event on the touch screen 151 (S106). Here, the controller 180 may control the second object such that the second object is gradually moved from the outside of the screen to the inside of the screen. In this case, the controller 180 may display a dynamic wavelength on the first object based on the movement path of the second object. For example, the control unit 180 controls the first object so that the second object moves as if floating over the first object having the liquid attribute, and the wavelength is displayed along the path along which the second object moves.

FIG. 6 illustrates an example of displaying a second object. In Fig. 6, the case where the second object is a glass bottle will be described as an example.

6, when a message is received through the wireless communication unit 110 in a lock screen state, the controller 180 displays a second object 6a indicating that a message has been received on the touch screen 151 (S401, S402). The control unit 180 controls the second object 6a to gradually move from the outside of the screen to the inside of the screen. The controller 180 displays a wave on the surface of the first object 3a about the second object 6a as the second object 6a moves into the screen, Is expressed as floating over the first object (3a) of the attribute.

Referring again to FIG. 2, the controller 180 displays information related to the event on the touch screen 151 (S108) while the second object notifying the occurrence of the event is touched (S107). For example, when a message is received in the lock screen state, the control unit 180 displays a second object on the touch screen 151 indicating that the message has been received. Also, when the second object is touched, it displays the received message or sender information of the received message on the touch screen 151. [

FIG. 7 illustrates an example of displaying information related to an event occurring in a lock screen state.

7, when a message is received through the wireless communication unit 110 in the lock screen state, the control unit 180 displays a glass bottle, which is the second object 6a indicating that the message is received, on the touch screen 151 . When the second object 6a displayed on the touch screen 151 is touched (S501), the control unit 180 extracts the message 6b from the glass bottle that is the second object 6a (S502). Further, the message 6b taken out from the glass bottle 6a is unfolded and displayed on the touch screen 151 (S503). Accordingly, it is possible for the user to confirm the received message or e-mail without releasing the lock screen state.

Referring again to FIG. 2, the control unit 180 receives a release request for the lock screen state. The control unit 180 may receive a release request for the lock screen state based on the movement of the electronic device 100 that receives a specific key through the user input unit 130 or is obtained through the sensing unit 140. [ The motion of the electronic device 100 can be obtained through the sensing unit 140. [ The sensing unit 140 may include at least one sensor such as a gyroscope, a magnetic sensor, and an accelerometer. The sensing unit 140 can acquire the rotation speed or the angular velocity of the rotation of the electronic device 100 on the axis line, that is, the rotation speed of the electronic device 100, using the gyro sensor. Also, the sensing unit 150 can acquire the gravitational acceleration according to the movement of the electronic device 100 through the acceleration sensor. Also, the sensing unit 150 can acquire the orientation of the electronic device 100 like a compass through the geomagnetic sensor. Accordingly, the sensing unit 130 senses the acceleration of the electronic device 100 based on at least one of the angular velocity acquired through the gyro sensor, the gravitational acceleration acquired through the acceleration sensor, and the orientation of the electronic device 100 acquired through the geomagnetic sensor. It is possible to precisely acquire the motion.

Upon receiving a release request for the lock screen status (S109), the controller 180 determines whether the user authentication is required (S110). If user authentication is required to release the lock screen state, the controller 180 performs a user authentication process (S111). If the user authentication is successful (S112), the control unit 180 cancels the lock screen state. In addition, as the lock screen state is released, the first object is controlled so that the twenty-first object gradually disappears (S113). If the user authentication is not required, the control unit 180 ends the lock screen state without user authentication when the lock screen state is requested to be released.

FIG. 8 shows an example of releasing the lock screen state through user authentication.

Referring to FIG. 8, the controller 180 displays a transparent first object 3a on the touch screen 151 with the liquid attribute as it enters the lock screen state while displaying the menu screen 4a (S601 ). When the release of the lock screen state is requested, the controller 180 performs the user authentication process using the face recognition. The control unit 180 notifies the user that the current user authentication process is being performed by displaying the image photographed by the camera 121 on the touch screen 121 during the user authentication process in operation S602. In the user authentication process, the control unit 180 reads the first face recognition information used for user authentication from the memory 160 to release the lock screen state. Also, the controller 180 acquires the second face recognition information through image recognition of the image photographed through the camera 121. The control unit 180 determines whether the user authentication is successful by comparing the acquired second face recognition information with the first face recognition information read from the memory 160. [ If the user authentication is successful, the controller 180 controls the first object 3a so that the first object 3a gradually disappears from the screen (S603). Also, if the first object 3a disappears from the screen, the lock screen state is canceled (S604).

Referring to FIG. 8, the controller 180 controls the first object 3a such that the first object 3a having the liquid attribute moves in a specific direction, thereby reducing the display area and finally disappearing from the screen. Here, the direction in which the first object 3a moves may be a predetermined direction as the lock screen state is released. In addition, the direction in which the first object 3a moves may be determined based on the movement of the electronic device 100 acquired through the sensing unit 140 as the lock screen state is released. In the latter case, the control unit 180 acquires the motion of the electronic device 100 through the sensing unit 140, and recognizes the posture of the electronic device 100 based on the obtained motion. Then, the direction in which the first object 3a moves is determined based on the attitude of the electronic device 100.

According to an embodiment of the present invention, the electronic device 100 provides a user-friendly and emotional interface in the process of entering and releasing the lock screen state.
