Different brands of smart watch devices provide different methods for lighting the screen. For example, Samsung's Gear watch, when the user raises the arm, the screen is lit; the MOTO360 watch is in the off-screen state, and the user taps the dial of the watch to light up the screen. These methods of lighting the screen do not give users a very good experience, and to a certain extent also affect the standby time of smart watches. For example, Samsung Gear watches, when users move their arms, they do not want to light up the screen to view information, but smart watches The acceleration sensor inside the watch will light up the screen when it detects that the user’s arm is moving. At this time, it is redundant to light up the screen. After the display of the smart watch is lit, the standby time will be shortened.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the embodiment of the present invention, after determining that the user's arm is in a moving state, it is judged whether there is an eyeball focused on the display screen of the smart watch. If an eyeball is focused on the display screen and the focusing time is greater than or equal to the set time threshold, the For the display screen of the smart watch, if no eyeballs are focused on the display screen of the smart watch or the focus time is less than the set time threshold, the display screen of the smart watch will not be lit, so that the smart watch screen can be better solved. The problem of being wrongly lit.

The realization of the present invention is described in detail below in conjunction with specific embodiment:

Embodiment one

Figure 1 shows the implementation process of the method for lighting the screen provided by Embodiment 1 of the present invention, which is described in detail as follows:

In step S101, it is determined whether the user's arm is in a motion state.

In the embodiment of the present invention, the state of the user's arm is tracked through the acceleration sensor installed on the smart watch. The smart watch can obtain the real-time data collected by the acceleration sensor, and calculate the absolute value of the contrast difference between the real-time data and the sample data in the X, Y, and Z axes. The sample data is when the user's arm is in a static state. For the data collected by the acceleration sensor, if one of the absolute values of the contrast differences between the real-time data and the sample data in the X, Y, and Z axes is greater than or equal to the set threshold M, then it can be determined that the user’s arm in motion.

Specifically, the acceleration sensor will collect the data of the user's arm in the three-dimensional direction, which is generally represented by the X axis, the Y axis, and the Z axis. The data in the Z axis direction is greater than 0. When the user's arm is at rest, the data collected by the acceleration sensor is used as sample data and stored in the memory.

When the user's arm is in motion, the acceleration sensor will collect corresponding data. In the three axis directions of X, Y, and Z, compare the collected real-time data (the collected data may be greater than 0 or less than 0) with the sample data stored in the memory. Specifically, three values of Xabs, Yabs, and Zabs can be used to represent the absolute value of the difference between the real-time data collected by the acceleration sensor in the directions of the X, Y, and Z axes and the sample data stored in the memory. When one of the values of Xabs, Yabs, and Zabs is greater than or equal to the set threshold M, it means that the user's arm is in motion at this time, and step S102 can be executed to immediately wake up the camera through the application. If the data of Xabs, Yabs, and Zabs are all less than the set threshold M, it can be determined that the user's arm is in a static state and the camera will not be woken up.

In step S102, it is judged whether there is an eyeball focused on the display screen of the smart watch, if yes, execute step S103, if not, execute step S105.

In the embodiment of the present invention, the environment of the smart watch is scanned by a camera installed on the smart watch, and it is determined according to the scanning result whether eyeballs are focused on the display screen of the smart watch.

Specifically, when it is determined in step S101 that the user's arm is in a motion state, the camera can be woken up by the application, and the environment of the smart watch can be scanned through the camera, and the processor of the smart watch can determine whether there is an eyeball focused on it according to the scanning result of the camera. on the display of the smart watch.

In step S103, it is judged whether the focusing time of the eyeballs on the display screen is greater than or equal to a preset time threshold, if yes, execute step S104, otherwise execute step S105.

In the embodiment of the present invention, when the camera detects that the eyeball is focused on the display screen of the smart watch, the processor of the smart watch compares the focusing time of the eyeball with a preset time threshold, and when the focusing time is greater than or equal to the preset time threshold When the time threshold is reached, execute step S104 to turn on the display screen of the smart watch; otherwise execute step S105 to not turn on the screen of the smart watch.

Specifically, the preset time threshold may be 500 milliseconds.

In step S104, the display screen of the smart watch is turned on.

In the embodiment of the present invention, if step S103 determines whether the focusing time of the eyeballs on the display screen is greater than or equal to a preset time threshold, the screen of the smart watch is turned on.

In step S105, the display screen of the smart watch is not turned on.

In the embodiment of the present invention, if step S103 determines whether the focusing time of the eyeballs on the display screen is greater than or equal to the preset time threshold, if the result of the determination is that the focusing time of the eyeballs on the display screen is less than the preset time threshold, then do not click Brighten the screen of the smart watch.

In addition, if it is determined in step S102 that no eyeballs are focused on the display screen of the smart watch, the screen of the smart watch is not turned on.

In this embodiment, after determining that the user's arm is in a moving state, it is determined whether there is an eyeball focused on the display screen of the smart watch, and if the eyeball is focused on the display screen and the focusing time is greater than or equal to the set time threshold, the smart watch is turned on If there is no eyeball focusing on the display screen of the smart watch or the focus time is less than the set time threshold, the display screen of the smart watch will not be lit, so as to better solve the problem that the screen of the smart watch is accidentally clicked The problem of brightening, the screen will not be frequently mistakenly turned on, which reduces the power consumption of smart watches to a certain extent, improves the battery life of smart watches, and users also have a good experience during use. The smart watch provided by the prior art overcomes the problem that the screen of the smart watch is turned on when the arm movement is detected, and the screen may be turned on by mistake, thereby affecting the standby time and shortening the problem.

It should be understood that in the embodiment of the present invention, the sequence numbers of the above-mentioned processes do not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, rather than the implementation process of the embodiment of the present invention. constitute any limitation.
