In the embodiment of the application, a hand-raising gesture rule is preset in wearable equipment, after the wearable equipment acquires acceleration data and angular velocity data in a screen-off state, the wearable equipment judges whether the hand-raising gesture rule is met according to the acceleration data and the angular velocity data, wherein the hand-raising gesture rule comprises a preset acceleration change trend and a preset angular velocity change trend corresponding to a hand-raising gesture, and the wearable equipment determines the acceleration change trend according to the acceleration data; determining the change trend of the angular speed according to the angular speed; when the acceleration variation trend accords with a preset acceleration variation trend and the angular speed variation trend accords with a preset angular speed variation trend, determining that the motion data accords with the hand-lifting gesture rule; and when the acceleration variation trend does not accord with the preset acceleration variation trend and/or the angular velocity variation trend does not accord with the preset angular velocity variation trend, determining that the motion data does not accord with the hand-lifting gesture rule.

It should be noted that the wearable device may set an acceleration threshold and an angular velocity threshold, and only when the acceleration data acquired by the acceleration sensor is greater than the acceleration threshold and the angular velocity data acquired by the angular velocity sensor is greater than the angular velocity threshold, the wearable device starts to determine the acceleration change trend within a period of time according to the acceleration data within a period of time, and determines the angular velocity change trend within a period of time according to the angular velocity data within a period of time. The set acceleration threshold and the angular velocity threshold can shield the wearable device from small-degree movement, such as movement of the wearable device caused by a swing arm of a user, so that the screen lightening times caused by the unintentional hand raising action are reduced, and the power consumption of hand raising detection is further reduced.

In the embodiment of the application, when the wearable device detects that human eyes watch the screen, the screen is lightened, and the screen is controlled to be switched from the screen-off state to the screen-on state.
Further, in the case that it is detected that the human eye is not watching the screen, the screen is controlled to be in a screen-off state.
Further, display contents, such as display time, display application icons, and the like, may be set in advance and displayed on the screen after the screen is controlled to be bright.
Illustratively, as shown in fig. 2, the smart watch is worn on the user's wrist, and the current time 12:26 is displayed on the smart watch when the user raises his hand and the user looks at the smart watch dial.
For example, for a smart watch, the process of implementing screen control is specifically shown in fig. 3, and includes:
1. when detecting that the arm of the user swings, detecting whether the user lifts the hand or not through an acceleration sensor and a gyroscope;
