The present disclosure relates to a method and an apparatus for minimizing interruptions during the execution of an application in a portable terminal.
FIG. 1 illustrates a high level structural block diagram of a portable terminal according to one embodiment of the present disclosure. The portable terminal includes a control unit 100, a communication unit 110, a display unit 120, an input unit 130, and a storage unit 140. The control unit 110 also includes an interrupt controlling unit 102.
The control unit 100 controls and processes an overall operation of the portable terminal, and controls and processes a function for executing an app supported by the portable terminal, according to user's control. In particular, according to the present disclosure, with the interrupt controlling unit 102, the control unit 100 controls and processes functions for displaying, when an event occurs during the execution of an app, information related to the event occurrence on a screen and controlling whether to interrupt the app based on user's control. The event can include call reception, message reception, and alarm generation. The event may refer to any event that may affect an app execution operation, because it is necessary to provide event-related information to the user through video signal or audio signal.
That is, the interrupt controlling unit 102 detects the occurrence of an event during the execution of an app. When an event occurs during the execution of an app, the interrupt controlling unit 102 controls and processes functions for displaying information representing the event occurrence on the display unit 120. Herein, the interrupt controlling unit 102 causes the app execution to be continued, while displaying the information representing the event occurrence on the screen. In certain embodiments, when detecting the reception of a call from a caller A while playing a video, the interrupt controlling unit 102 displays information indicating the reception of the call from caller A in a specified portion of the screen while continuing to play the video. In certain embodiments, the specified portion of the screen, in which the information representing the event occurrence is displayed, may be a top, bottom, left or right portion of the screen in order not to disturb the app execution.
Also, the interrupt controlling unit 102 detects a user's input through the input unit 130 and determines whether to interrupt the app by the event. That is, the interrupt controlling unit 102 controls and processes functions for comparing a user input with specified input modes. According to the comparison result, the interrupt controlling unit 102 will either interrupt the current app and execute another app which is related to the event, or display additional information related to the event while continuing the app execution, or disregard the event occurrence and continuing the app execution. In certain embodiments, when information representing the reception of a text message from a caller while playing a video is displayed in a specified portion and then the user touches and holds the information displayed in the specified portion of the screen for a specified time or more, the interrupt controlling unit 102 controls a function for interrupting the video play, executes a message managing app, and switches the screen for displaying the received message. Alternatively, when the user touches and left-drags the information displayed in the specified portion, the interrupt controlling unit 102 can display additional information related to the received message, that is, the content of the received message. Also, when the user touches and right-drags the information displayed in the specified portion of the screen, the interrupt controlling unit 102 can disregard the message reception and continue to play the video.
The communication unit 110 communicates with another node under the control of the control unit 100. The communication unit 110 controls and processes a function for converting radio frequency (RF) signal received through an antenna into baseband signal and providing the baseband signal to the control unit 100, and converting a baseband signal received from the control unit 100 into RF signal and transmitting the RF signal to another node through the antenna.
The display unit 120 displays a variety of status information, numerals, characters, and images that are generated during an operation of the portable terminal. In particular, the display unit 120 may display video signals on a screen with the execution of an app in the portable terminal and may display event-related information in a specified portion of the screen when an event occurs.
The input unit 130 can include one or more function keys or touch sensors. The input unit 130 provides the control unit 100 with data corresponding to a key pressed by the user or data corresponding to a position touched by the user. In certain embodiments, according to the present disclosure, when an event occurs during the execution of an app, the input unit 130 receives data for determining whether to interrupt the app from the user and provides the data to the control unit 100.
The storage unit 140 stores a variety of program and status information necessary during an operation of the portable terminal. In certain embodiments, the storage unit 140 stores various apps that are executable in the portable terminal. Also, when an event occurs in relation to an app that is being executed, the storage unit 140 stores information on a function that is to be performed based on user input. In certain embodiments, when a user drags in the left direction, the storage unit 140 stores information indicating the performance of a function for displaying additional information related to the event while maintaining the app execution state. When a user drags in the right direction, the storage unit 140 stores information indicating the performance of a function for disregarding the event while continuing the app execution state. When a user continues to touch at the same point for a specified time or more, the storage unit 140 stores information indicating the performance of a function for interrupting the app execution, executing an app corresponding to the event and switching the screen. In addition to the above input modes, the input mode can include a double touch, a curved touch, and a vertically-dragged touch.
The method described above in relation with FIG. 1 under of the present invention may be provided as one or more instructions in one or more software modules stored in the respective portable terminals.
FIG. 2 depicts a flowchart illustrating an operation process of a portable terminal according to one embodiment of the present disclosure.
In step 201, the portable terminal executes an app based on user's control. In certain embodiments, the portable terminal executes a video player app based on user's control.
In step 203, the portable terminal determines whether an event occurs during the app execution. When an event does not occur during the app execution, the portable terminal returns to step 201 and maintains the app execution state.
Alternatively, when an event occurs during the app execution, the portable terminal proceeds to step 205. In step 205, the portable terminal displays information representing the event occurrence on a screen while continuing the app execution operation. In certain embodiments, when detecting message reception while playing a video, the portable terminal displays information indicating the reception of a message from another user on the screen while continuing to play the video. Herein, in order not to interrupt the app execution, the portable terminal may display the information representing the event occurrence in a specified portion of the screen. In certain embodiments, when the app plays a video containing a caption, the portable terminal can display the information representing the event occurrence on a screen portion that does not overlap with a caption area.
In step 207, the portable terminal determines whether user input has been received. When user input has not been received for a specified time, the portable terminal proceeds to step 221. In step 221, the portable terminal removes the displayed information while continuing the app execution operation. Thereafter, the portable terminal returns to step 201. That is, when the portable terminal informs the user of the event occurrence during the app execution but a user input has not received for a specified time, the portable terminal continues the app execution in step 201 without executing an app related to the event, by determining that the user desires to disregard the event.
Alternatively, when a user input has received, the portable terminal proceeds to step 209. In step 209, the portable terminal compares the user input with the specified inputs and determines which function is to be performed.
When it is determined in step 209 that the user input a command corresponding to Display Additional Information among specified input modes, the portable terminal proceeds to step 211. In step 211, the portable terminal detects additional information related to the event and displays the additional information in a specified portion of the screen while maintaining the app execution. The additional information related to the event is detailed information of the event. In certain embodiments, when the event is message reception, the additional information can be the content of a received message. If the event is alarm generation, the additional information can be a detailed schedule corresponding to a generated alarm. Thereafter, the portable terminal returns to step 207. Herein, the input command corresponding to Display Additional Information can be a touch and drag from right to left. In this embodiment, the portable terminal may gradually move the displayed additional information from the right to the left of the screen in accordance with a drag operation of the user, thereby providing the effect that the additional information flows from the right to the left of the screen.
In another embodiment, when it is determined in step 209 that the user has input a command corresponding to Branch among the specified input commands, the portable terminal proceeds to step 213. In step 213, the portable terminal interrupts the app execution, executes an event-related app and switches the screen for the event related app. Herein, the input command corresponding to Branch can be a touch performed on the screen for a specified time or more. In certain embodiments, in the state where a message has been received during video play and information indicating the message reception is displayed on the screen, when the user touches a display portion of the information for a specified time or more, the portable terminal interrupts the video play, executes a message managing app and switches to a screen for displaying, a received message.
In step 217, the portable terminal determines whether the event-related app has ended. When the event-related app ends, the portable terminal proceeds to step 219. In step 219, the portable terminal re-executes the interrupted app. Thereafter, the portable terminal returns to step 203.
In another embodiment, when it is determined in step 209 that the user has input a command corresponding to Disregard among the specified input commands, the portable terminal proceeds to step 215. In step 215, the portable terminal removes the information displayed on the screen in step 205 while continuing to execute the app. Thereafter, the portable terminal returns to step 201. Herein, the command corresponding to Disregard can be a touch dragged from left to right. In this embodiment, the portable terminal can gradually move the displayed information from the left to the right of the screen in accordance with a drag operation of the user, thereby providing the effect that the displayed information gradually disappears to the right of the screen.
As described above, when an event occurs during the execution of an app, the present invention provides information on the event to the user while maintaining the app execution state, thus allowing the user to select whether to interrupt the app and then branch (or switch) to another app which is related to the event, or to disregard the event occurrence and maintaining the app execution.
