Abstract

A wrist-worn device control method is disclosed. The method includes: collecting first motion data of a wrist-worn device, where the first motion data includes angular velocity information and acceleration information of the wrist-worn device; and identifying, based on the first motion data of the wrist-worn device, that the wrist-worn device changes from a first posture to a second posture, and playing, by the wrist-worn device, media information, where the media information is at least one of a speech message, a text message, or incoming call information that are received by the wrist-worn device, and information displayed by the wrist-worn device, and the second posture is a posture in which a hand of a user wearing the wrist-worn device is close to an ear of the user. Therefore, a message can be played without occupying two hands of the user, interaction is convenient, and user experience is good.

6 . The method according to claim 5 , wherein a watch face of the wrist-worn device faces a human face or the ear.

7 . The method according to claim 1 , wherein the second posture is the posture in which the hand of the user wearing the wrist-worn device is close to the ear of the user, wherein the wrist-worn device is close to an ear on a same side of the hand of the user wearing the wrist-worn device, and a forearm of the hand of the user wearing the wrist-worn device points downward, or a forearm of the hand of the user wearing the wrist-worn device is parallel to a horizontal plane.

8 . The method according to claim 1 , wherein when the wrist-worn device is in the first posture, the wrist-worn device determines, based on at least one of a motion status of the wrist-worn device or environmental illumination data of the wrist-worn device, to display a target identifier, so as to indicate the user to listen to the media information by ear.

9 . The method according to claim 1 , wherein when identifying, based on the first motion data of the wrist-worn device, that the wrist-worn device changes from the first posture to the second posture, the wrist-worn device shields a touch control function, a knob function, or a button function.

10 . The method according to claim 1 , wherein when the media information is the incoming call information received by the wrist-worn device, the method further comprises:
