Abstract

A device and method of managing power are provided. The device includes a user input unit configured to receive a user input from a user, an output unit configured to output information based on the user input, and a controller configured to, when the user input is not received, determine whether or not an out-focus status in which the user does not use the device has started, determine, when it is determined that the out-focus status has started, a period in which the out-focus status is to be maintained based on information about a probability of the out-focus status according to a context of the device, and stop, when the period in which the out-focus status is to be maintained is equal to or greater than a reference time period, an application executed in the device.

Claims

1. A device comprising:

a user input unit configured to receive a user input from a user;

an output unit configured to output information, based on the user input; and

a controller configured to;

determine, when the user input is not received, whether an out-focus status in which the user does not use the device has started,

determine, when it is determined that the out-focus status has started, a period in which the out-focus status is to be maintained based on information about a probability of the out-focus status according to a context of the device, and

stop, when the period in which the out-focus status is to be maintained is equal to or greater than a reference time period, an application executed in the device.

2. The device of claim 1, wherein the out-focus status in which the user does not use the device indicates at least one of a status in which the output unit does not output the information or a status in which the user does not receive the information output from the output unit.

3. The device of claim 1, wherein the context of the device comprises at least one of a time, a location of the device, a status of the device, or an environment surrounding the location of the device.

4. The device of claim 1,

wherein, after the application is stopped, the user input unit is further configured to receive the user input from the user, and

wherein, when the user input is received from the user, the controller is further configured to resume the stopped application.

5. The device of claim 1,

wherein the output unit comprises a display unit configured to display the information,

wherein, when the user input is not received for a preset time period, the controller is further configured to inactivate the display unit, and

wherein, when the display unit is inactivated, the controller is further configured to determine that the out-focus status has started.

6. The device of claim 1, further comprising:

a communicator configured to receive a call connection request from a server,

wherein, when the call connection request is received, the output unit is further configured to output information indicating reception of the call connection request, and

wherein, when a user input for confirming the call connection request in response to the output information is not received, the controller is further configured to determine that the out-focus status has started.

7. The device of claim 6, wherein the controller is further configured to:

determine the period in which the out-focus status is to be maintained, based on a value of a probability of the out-focus status corresponding to a time period after the out-focus status has started,

wherein the value of the probability is obtained from among information about probabilities of the out-focus status according to time.

8. The device of claim 1,

wherein the controller is further configured to determine reliability of the period in which the out-focus status is to be maintained based on information about the probability of the out-focus status according to the context of the device, and

wherein, when the reliability of the period in which the out-focus status is to be maintained is equal to or greater than a reference, the controller is further configured to stop the application executed in the device.

9. The device of claim 8,

wherein the information about the probability of the out-focus status according to the context of the device comprises information about probabilities of the out-focus status according to locations of the device,

wherein the controller is further configured to determine the reliability of the period in which the out-focus status is to be maintained based on a probability value corresponding to a location of the device when the out-focus status has started, and

wherein the probability value is obtained from among the information about the probabilities of the out-focus status according to the locations of the device.

10. The device of claim 8,

wherein the information about the probability of the out-focus status according to the context of the device comprises information about probabilities of the out-focus status according to statuses of the device,

wherein the controller is further configured to determine the reliability of the period in which the out-focus status is to be maintained based on a probability value corresponding to a status of the device when the out-focus status has started, and

wherein the probability value is obtained from among the information about the probabilities of the out-focus status according to the statuses of the device.

11. The device of claim 1, further comprising:

a communicator configured to exchange data about the application with the server, even if the user input is not received,

wherein, when the period in which the out-focus status is to be maintained is equal to or greater than the reference time period, the controller is further configured to control the communicator to stop exchanging the data.

12. The device of claim 1, wherein, even if information about an event is received from a server, the controller is further configured not to request the communicator to output information indicating reception of the event when the period in which the out-focus status is to be maintained is equal to or greater than the reference time period.

13. The device of claim 1, further comprising:

a communicator configured to receive updated data with respect to the application from a server even if the user input is not received,

wherein, when the period in which the out-focus status is to be maintained is equal to or greater than the reference time period, the controller is further configured to control the communicator not to receive the updated data from the server.

14. A method of managing power comprising:

determining, when a user input is not received from a user, whether an out-focus status in which the user does not use a device has started;

determining, when it is determined that the out-focus status has started, a period in which the out-focus status is to be maintained based on information about a probability of the out-focus status according to a context of the device; and

stopping, when the period in which the out-focus status is to be maintained is equal to or greater than a reference time period, an application executed in the device.

15. The method of claim 14, wherein the out-focus status in which the user does not use the device, indicates at least one of a status in which an output unit of the device does not output information or a status in which the user does not receive the information output from the output unit of the device.

16. The method of claim 14, wherein the context of the device comprises at least one of a time, a location of the device, a status of the device, or an environment surrounding the location of the device.

17. The method of claim 14, further comprising:

after the application is stopped, receiving the user input from the user; and

when the user input is received from the user, resuming the stopped application.

18. The method of claim 14, wherein the determining of the out-focus status comprises:

when the user input is not received for a preset time period, inactivating a screen of the device; and

when the screen is inactivated, determining that the out-focus status has started.

19. The method of claim 14, further comprising:

when a call connection request is received from a server, outputting information indicating reception of the call connection request,

wherein, when a user input for confirming the call connection request in response to the output information is not received, the determining of the out-focus status comprises determining that the out-focus status has started.

20. A non-transitory computer-readable recording medium having recorded thereon a program for executing the method according to claim 14.
