First Claim
Patent Images
1. A control method of an electronic device, comprising:
- detecting a gesture through a sensor module by comparing the detected gesture to a predetermined gesture;
activating a camera of the electronic device, when the detected gesture corresponds to the predetermined gesture;
photographing a plurality of images of a user during a predetermined time period using the camera;
determining whether the user has been staring at the electronic device during the predetermined time period based on the plurality of images, wherein determining whether the user has been staring at the electronic device comprises;
identifying at least one of the user'"'"'s face contours or the user'"'"'s pupils from the plurality of images, anddetermining that the user has been staring at the electronic device during the predetermined time period if at least one of a change detected in the user'"'"'s face contours or a change detected in the user'"'"'s pupils is less than a predetermined threshold for the predetermined time period; and
performing a predetermined function, when it is determined that the user has been staring at the electronic device during the predetermined time period, wherein performing the predetermined function comprises;
connecting the electronic device to a second electronic device through communication,determining whether an application is being executed in the second electronic device,displaying information corresponding to the application being executed in the second electronic device, when determining that the application is being executed in the second electronic device, anddisplaying an idle mode, when determining that the application is not being executed in the second electronic device.

Abstract
Provided herein is a control method of an electronic device. A gesture is detecting and a plurality of images of a user are photographed, if the gesture substantially corresponds to a predetermined gesture. A predetermined function is performed, if the change detected in the images is less than a predetermined threshold during a predetermined time period.

7. An electronic device comprising:
-
a camera module; a sensor module; communication unit; a display unit; and a processor configured to; detect a gesture through the sensor module by comparing the detected gesture to a predetermined gesture; activate the camera module, when the detected gesture corresponds to the predetermined gesture; control the activated camera module to photograph a plurality of images of a user during a predetermined time period; determine whether the user has been staring at the electronic device during the predetermined time period based on the plurality of images, wherein determine whether the user has been staring at the electronic device comprises; identify at least one of the user'"'"'s face contours or the user'"'"'s pupils from the plurality of images, and determine that the user has been staring at the electronic device during the predetermined time period if at least one of a change detected in the user'"'"'s face contours or a change detected in the user'"'"'s pupils is less than a predetermined threshold for the predetermined time period; and perform a predetermined function, when it is determined that the user has been staring at the electronic device during the predetermined time period, wherein perform the predetermined function comprises; connect the electronic device to a second electronic device through the communication unit, determine whether an application is being executed in the second electronic device, display information in the display unit corresponding to the application being executed in the second electronic device, when determined that the application is being executed in the second electronic device, and display an idle mode in the display unit, when determined that the application is not being executed in the second electronic device. - View Dependent Claims (8, 9, 10, 11, 12)

13. A non-transitory and physical computer-readable medium storing instructions therein which upon execution instructs at least one processor configured to:
-
detect a gesture through a sensor module by comparing the detected gesture to a predetermined gesture; activate a camera of an electronic device, when the detected gesture corresponds to the predetermined gesture; photograph a plurality of images of a user during a predetermined time period using the camera; determine whether the user has been staring at the electronic device during the predetermined time period based on the plurality of images, wherein determine whether the user has been staring at the electronic device comprises; identify at least one of the user'"'"'s face contours or the user'"'"'s pupils from the plurality of images, and determine that the user has been staring at the electronic device during the predetermined time period if at least one of a change detected in the user'"'"'s face contours or a change detected in the user'"'"'s pupils is less than a predetermined threshold for the predetermined time period; and perform a predetermined function, when it is determined that the user has been staring at the electronic device during the predetermined time period, wherein perform the predetermined function comprises; connect the electronic device to a second electronic device through communication, determine whether an application is being executed in the second electronic device, display information corresponding to the application being executed in the second electronic device, when determined that the application is being executed in the second electronic device, and display an idle mode, when determined that the application is not being executed in the second electronic device.
