FIG. 2 is a functional block diagram of the wearable device control system of FIG. 1 of the present invention.

The wearable device control system 30 operates in the wearable device 3, which includes, in addition to the wearable device control system 30, a storage 340, a processor 350, and a sensor 360 connected through a data line or a signal line. The wearable device control system 30 includes an acquisition module 300, an analysis module 310, a generation module 320, and a control module 330. The stylized code of modules 300-330 is stored in memory 340, which executes the programmed code to implement the functions provided by wearable device control system 30. The sensor 360 is configured to monitor the eye 1 of the user wearing the wearable device 3, so that the user can control the wearable device 3 through the eye 1, for example, starting, closing, and switching the wearable device. 3 operations such as running software. The sensor 360 can be, but is not limited to, an infrared sensor, a micro camera, or a combination of the two.

The acquisition module 300 is configured to acquire the information of the eye 1 through the sensor 360 within a preset time (within 1 second).

When the sensor 360 is an infrared sensor, the information of the eye 1 is the signal intensity of the infrared light reflected from the eye. Specifically, the infrared sensor sends infrared rays to the eye 1 every time, and collects infrared rays reflected from the eye 1. If the signal intensity of the infrared rays reflected from the eye 1 is greater than or equal to a preset value, it indicates that the eye 1 has no closed eyes. That is to say, when the eyes are not closed, the infrared rays emitted by the infrared sensor reach the eyeball. Since the eyeball is a smooth surface, the signal intensity of the infrared rays emitted from the eyeball is greater than or equal to a preset value. If the signal intensity of the infrared light reflected from the eye 1 is lower than the preset value, it indicates that the eye 1 is closed, that is, when the eye is closed, the infrared ray emitted by the infrared sensor reaches the eyelid, since the surface of the eyelid is rough, from the eyelid The reflected signal intensity of the infrared rays is lower than the preset value. The number of times the eye 1 blinks within a preset time can be obtained by the signal intensity of the infrared light reflected from the eye.

When the sensor 360 is a miniature camera, the information of the eye 1 is a picture of the eye 1. Specifically, the miniature camera takes a picture of the eye 1 within a preset time, and determines whether the eyeball is included in the captured image through a picture analysis algorithm. If the captured image includes an eyeball, it indicates that the eye 1 has no closed eyes. If the eyeball is not included in the picture taken, it means that the eye 1 is closed. Through the picture of the eye 1, the number of times the eye 1 blinks in the preset time can be obtained.

The analysis module 310 is configured to analyze the number of times the eye 1 blinks in a preset time according to the information of the eye.

Specifically, if the information of the eye 1 is the signal intensity of the infrared light reflected from the eye, when the signal intensity of the infrared rays reflected from the eye 1 is different twice, it indicates that the eye blinks once and can be obtained by the above method. The number of times eye 1 blinks within a preset time.

If the information of the eye 1 is the picture of the eye 1, when the picture of two consecutive eyes 1 has an eyeball of one eye and the eye of the other eye has no eyeball, it indicates that the eye 1 blinks once, through The above method can obtain the number of times the eye 1 blinks in a preset time.

The generating module 320 is configured to generate a corresponding control instruction according to the number of blinks. For example, when the number of blinks is two, a start command is generated, which is used to start the wearable device 3, and when the number of blinks is three, a close command is generated, which is used to close the current running in the wearable device 3. The software generates a switching instruction when the number of blinks is four times, and the switching instruction is used to switch a webpage in a browser or play a video file of a certain video software.

The control module 330 is configured to control the wearable device 3 according to the control instruction. For example, if the control command is a start command, the wearable device 3 is activated. If the control command is a close command, the software currently running by the wearable device 3 is turned off. If the control command is a switching instruction, the webpage in the browser is switched or the video file of a certain video software is played.

When the sensor 360 is an infrared sensor, the information of the eye 1 is the signal intensity of the infrared light reflected from the eye. Specifically, the infrared sensor sends infrared rays to the eye 1 every time, and collects infrared rays reflected from the eye 1. If the signal intensity of the infrared rays reflected from the eye 1 is greater than or equal to a preset value, it indicates that the eye 1 has no closed eyes. That is to say, when the eyes are not closed, the infrared rays emitted by the infrared sensor reach the eyeball. Since the eyeball is a smooth surface, the signal intensity of the infrared rays emitted from the eyeball is greater than a preset value. If the signal intensity of the infrared light reflected from the eye 1 is lower than the preset value, it indicates that the eye 1 is closed, that is, when the eye is closed, the infrared ray emitted by the infrared sensor reaches the eyelid, since the surface of the eyelid is rough, from the eyelid The reflected signal intensity of the infrared rays is lower than the preset value. The number of times the eye 1 blinks within a preset time can be obtained by the intensity of the infrared light reflected from the eye each time.

When the sensor 360 is a miniature camera, the information of the eye 1 is a picture of the eye 1. Specifically, the miniature camera takes a picture of the eye 1 within a preset time, and determines whether the eyeball is included in the captured image through a picture analysis algorithm. If the captured image includes an eyeball, it indicates that the eye 1 has no closed eyes. If the eyeball is not included in the picture taken, it means that the eye 1 is closed. Through the picture of the eye 1, the number of times the eye 1 blinks in the preset time can be obtained.

In step S20, the analysis module 310 analyzes the number of times the eye 1 blinks in a preset time according to the information of the eye.

Specifically, if the information of the eye 1 is the signal intensity of the infrared light reflected from the eye, when the signal intensity of the infrared rays reflected from the eye 1 is different twice, it indicates that the eye blinks once and can be obtained by the above method. The number of times eye 1 blinks within a preset time.

If the information of the eye 1 is the picture of the eye 1, when the picture of two consecutive eyes 1 has an eyeball of one eye and the eye of the other eye has no eyeball, it indicates that the eye 1 blinks once, through The above method can obtain the number of times the eye 1 blinks in a preset time.

In step S30, the generation module 320 generates a corresponding control instruction according to the number of blinks. For example, when the number of blinks is two, a start command is generated, which is used to start the wearable device 3, and when the number of blinks is three, a close command is generated, which is used to close the current running in the wearable device 3. The software generates a switching instruction when the number of blinks is four times, and the switching instruction is used to switch a webpage in a browser or play a video file of a certain video software.

In step S40, the control module 330 controls the wearable device 3 according to the control command. For example, if the control command is a start command, the wearable device 3 is activated. If the control command is a close command, the software currently running by the wearable device 3 is turned off. If the control command is a switching instruction, the webpage in the browser is switched or the video file of a certain video software is played.
