Imagine that when the visually impaired person is overwhelmed by the crowd, he simply strokes the side of the glasses with his hand, collects external information through the two cameras on the glasses, and automatically calculates the spatial distribution of the obstacle. And identifying the object, and then converting the result into an audio signal, which is transmitted to the user through the conductive earphone to help the visually impaired to recognize the surrounding environment. This "Angel Eye" developed for the visually impaired is developed by Shanghai Haoguan Electronic Technology Co., Ltd. (hereinafter referred to as "Zhaoguan Electronics"). “肇观†means “opening the vision†and hopes to “give†all the smart devices: drones, unmanned vehicles, robots, VR, AR, etc., thus opening a new era of artificial intelligence. Feng Xinpeng, the founder of Yanguan Electronics, graduated from Southampton University with a master's degree in microelectronics. He worked for SMIC for two and a half years and then worked for AMD for more than ten years. More than ten years of technical accumulation, as well as the enthusiasm for artificial intelligence, let Feng Xinpeng resolutely decided to "go to the sea" and founded the company. Feng Xinpeng said, "Selecting this time to start a business means that the time is ripe, whether it is industrial technology or personal preparation." In the face of the artificial wave of technology, he hopes to use technology to help more people. Relevant data show that there are currently 13 million visually impaired people in China. However, due to the imperfect infrastructure of the current visually impaired people in China, there are many unsafe factors in the travel of visually impaired people. The "Angel Eye" may improve this problem. Wearing an "Angel Eye" is like taking 40 virtual canes "There is no sound in front of me, I can go forward boldly. When I hear the prompt, the prompt is getting more and more urgent. It shows that I am getting closer and closer to the obstacle. At this time I am going around, there is no sound in front. There are obstacles, and very Near. I heard the sound of the door, so I can find the door handle." The reporter saw that the staff brought the blindfold to simulate the blind travel, wearing artificial intelligence glasses, avoiding obstacles, identifying objects, positioning, and navigation, and the whole process was completed. In addition, " Angel Eye " can also read text, such as identifying the denomination of money, looking at the various complexities such as the house number. The reporter went to the convenience store and experimented with the blindfolded money to buy things. But I feel how the sound is a bit light. Researcher introduction: Because this earphone is bone conduction, it is not in-ear type on the market, so the sound will be slightly lighter. In order to block the only "ear" that does not allow blind people to obtain outside information, the glasses innovatively use bone conduction voice broadcast. Vitamin A is a fat-soluble vitamin, an organic compound whose chemical formula is C20H30O. It is stable to heat, acid, and alkali, and is easily oxidized. Ultraviolet rays can promote its oxidative damage. Vitamin A includes A1 and A2, and A1 is retinol. Vitamin A2 is 3-dehydroretinol, and its physiological activity is 40% of that of vitamin A1.

Vitamin A has a variety of physiological functions such as promoting growth, reproduction, maintaining normal secretion of bones, epithelial tissue, vision and mucosal epithelium, and vitamin A and its analogs have the effect of preventing precancerous lesions. Deficiency manifests as growth retardation, impaired dark adaptation and night blindness. Dry eye disease occurs due to dryness, desquamation, hyperkeratosis, and decreased secretion of lacrimal glands of epidermal and mucosal epithelial cells. In severe cases, corneal softening, perforation and blindness occur. Respiratory epithelial cells become keratinized and lose their cilia, making them less resistant to infection. The recommended intake of vitamin A (RNI) for adults in my country is 800 μg retinol activity equivalent per day for men and 700 μg retinol activity equivalent per day for women. [2] Foods rich in vitamin A include liver, egg yolk, and milk powder of poultry and livestock. Carotene can be converted into vitamin A in the mucosa of the small intestine, red-yellow and dark green vegetables. Fruits contain more carotene.
