5 illustrates an example of an operation of an electronic device according to various embodiments of the present disclosure. The operations shown in FIG. 5 may be performed by the electronic device 101 (eg, the processor 120).

Referring to FIG. 5, in operation 501, the processor 120 may monitor a posture of the electronic device 101 using the sensor module 176. For example, the processor 120 uses at least one of the gyro sensor 301, the gravity sensor 302, or the acceleration sensor 303 to rotate the electronic device 101 and the electronic device 101. The change in the attitude of the electronic device 101 can be identified by monitoring the change in the orientation of) or the inclination of the electronic device 101.

The processor 120 may monitor a change in the posture of the electronic device 101 even when the processor 120 is in an active state or an inactive state. For example, while the main processor 121 is in an inactive (eg, sleep) state, the coprocessor 123 (eg, a sensor hub processor) may be in a position of the electronic device 101. The sensor module 176 can be controlled to detect a change. The processor 120 may control the sensor module 176 to detect a change in posture of the electronic device 101 while in the active state of executing any application (eg, a message application).

In some embodiments, the processor 120 may monitor a change in posture of the electronic device 101 only when the electronic device 101 is in a designated state. For example, the processor 120 may display the electronic device 101 while the electronic device 101 displays the home screen, while the electronic device 101 displays the lock screen, and while the screen of the electronic device 101 is turned off (eg, The electronic device 101 in the idle state or always on display (AOD) state, or during execution of a specified application (e.g., a messenger application, a message application, etc.) in the foreground. You can monitor your posture changes. However, the present invention is not limited thereto.

In operation 502, the processor 120 may identify that the posture of the electronic device 101 is changed. For example, the processor 120 identifies that the orientation of the electronic device 101 changes via a sensor module 176 (eg, a gyro sensor 301 (or a gyroscope)). can do.
