Example one
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for outputting video content according to an embodiment of the present invention. The electronic equipment is provided with a display screen, and the display screen comprises an LCD screen and an ink screen. As shown in fig. 1, the method may include the following steps.
101. When a video playing instruction input by a user is received, the electronic equipment plays a video through the LCD screen.
In the embodiment of the present invention, the electronic device may be a family education machine, a learning tablet, or the like, and the embodiment of the present invention is not limited. Among other things, the electronic device may support network technologies including, but not limited to: global system for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), wideband Code Division Multiple Access (W-CDMA), CDMA2000, IMT Single Carrier (IMT Single Carrier), enhanced data rate GSM Evolution (enhanced data Rates for GSM Evolution, EDGE), Long-Term Evolution (Long-Term Evolution, LTE), advanced Long-Term Evolution (LTE), Time-Division Long-Term Evolution (Time-Division LTE, TD-LTE), High-Performance Radio Local Area Network (High-Performance Radio Local Area Network, High-Performance lan), High-Performance wide Area Network (High wan), Local multi-point SDMA (Local multi-point Multiple Access, LMDS), Worldwide Interoperability for Microwave (WiMAX), bluetooth (orthogonal frequency Division multiplexing), and High-capacity space Division multiplexing (ZigBee-HC) Universal Mobile Telecommunications System (UMTS), universal mobile telecommunications system time division duplex (UMTS-TDD), evolved high speed packet access (HSPA +), time division synchronous code division multiple access (TD-SCDMA), evolution data optimized (EV-DO), Digital Enhanced Cordless Telecommunications (DECT), and others.
In the embodiment of the invention, the display screen arranged on the electronic equipment can comprise an LCD screen and an ink screen. The electronic equipment can play videos through the LCD screen due to the fact that the interaction capacity of the LCD screen is strong; because the ink screen can simulate the effect of a book through the electronic paper display technology, the effect of protecting the eyesight of a user is realized, and therefore, the electronic equipment can output the learning text related to the current playing content of the video through the ink screen.
In the embodiment of the invention, it can be understood that the long-time watching of the video can cause eye fatigue of the user, and the continuous watching of the video at the moment not only reduces the learning efficiency of the user, but also influences the eyesight of the user. Therefore, as an alternative implementation, the electronic device may perform the following operations:
controlling a camera module of the electronic equipment to shoot so as to obtain a user image;
judging whether the user is in an eye fatigue state or not according to the user image;
if yes, the LCD screen and the ink screen are closed, and sleep-aid music is played to help the user to enter the sleep state.
By implementing the optional implementation mode, whether the user is in an eye fatigue state or not is judged in the process of watching the video by the user, if so, the LCD screen and the ink screen are closed, the LCD screen and the ink screen are in a standby state, and the sleep-aid music is played to help the user to enter a sleep state, so that the power consumption of the electronic equipment can be reduced, and the user can be in a work and leisure combination.
Specifically, as an optional implementation manner, the manner in which the electronic device determines whether the user is in the eye fatigue state according to the user image may be:
judging whether the expression characteristics of the user in the user image are matched with preset yawning expression characteristics or not; if yes, determining that the user is in an eye fatigue state; if not, determining that the user is not in the eyestrain state.
By implementing the optional implementation mode, a method for judging whether the user is in the eyestrain state is provided, and whether the user is in the eyestrain state can be judged according to whether the user yawns.
Specifically, as another optional implementation manner, the manner in which the electronic device determines whether the user is in the eye fatigue state according to the user image may be:
recognizing the head action characteristics of a user by combining multiple frames of continuous user images shot by a camera module of the electronic equipment;
judging whether the head action characteristics are matched with preset nodding characteristics or not;
if the head action characteristics are matched with the preset nodding characteristics, further judging whether the eyes of the user are in an eye closing state; if yes, determining that the user is in an eye fatigue state; if not, it is determined that the user is not in an eyestrain state.
And if the head action characteristic does not match with the preset nodding characteristic, determining that the user is not in the eyestrain state.
Implementing the alternative embodiment, another method for judging whether the user is in the eyestrain state is provided, the user usually makes a trouble when being in the eyestrain state, and if the user is judged to be nodding and closing the eyes according to the user image, the user is shown to make a trouble at the moment, so that the user is judged to be in the eyestrain state.
In the embodiment of the invention, high-energy short-wave Blue light (Blue Laser) may exist in the light output by the LCD screen, and the high-energy short-wave Blue light may cause irreversible damage to the retina and the optic nerve of a user, so that the vision of the user is damaged. If the eyes of the user are too close to the LCD screen during the process of watching the video played by the LCD screen, the visual impairment of the user can be aggravated.
Therefore, as an alternative implementation, the LCD screen may be provided with a distance sensing module, and during the process of playing the video through the LCD screen, the electronic device may further perform the following steps:
monitoring a target distance between eyes of a user and an LCD screen in real time through a distance sensing module;
judging whether the target distance is smaller than a preset distance or not;
and if the distance is less than the preset distance, the LCD screen is closed, and eye protection information is output on the ink screen to prompt the user to pay attention to the eye protection.
By implementing the optional implementation mode, the distance between the eyes of the user and the LCD screen is judged, when the eyes of the user are too short-sighted away from the LCD screen, the LCD screen is closed in time and the user is reminded of paying attention to protect the eyes, and the harm to the eyes of the user caused by watching videos in a close range can be reduced.
102. The electronic equipment controls a camera module of the electronic equipment to shoot so as to obtain a facial image of a user.
In the embodiment of the invention, the electronic equipment can be provided with the camera module, and correspondingly, the electronic equipment can shoot the user through the camera module so as to obtain the facial image of the user.
103. And when the facial expression features in the facial image are matched with the preset query expression features, the electronic equipment acquires the current playing content of the LCD screen.
In the embodiment of the present invention, it can be understood that if a user does not understand the currently played content of the video or does not understand the currently played content of the video during the process of watching the video, a question will be generated, and accordingly, the facial expression of the user will change accordingly, for example, a question expression feature will be generated during the question.
104. The electronic device searches for a learning text matching the currently playing content.
In the embodiment of the present invention, the learning text is text data related to the currently played content of the video, such as a word definition, and the embodiment of the present invention is not limited.
