This design realizes a vision detection system, which can detect human visual acuity through gesture recognition technology. The system includes several modules: acquisition, data storage and conversion, gesture recognition and output control. And the camera, memory, display and speaker are connected externally. The visual icon "E" is displayed on the display screen, and then people use gestures to indicate the direction of "E". After the camera captures the image, the system recognizes and judges the direction of gesture, and then compares the correct direction to detect the visual acuity of people. Because the system eliminates manual detection, it is convenient, accurate and it saves manpower. The system realizes dynamic gesture interaction, being interesting and easy to be popularized.

Distance training is one of the important means of K12 teachers’ distance training. In the implementation of teachers’ distance training, there are some problems that the learning content is not very consistent with teachers demand, the instructional interaction is not real-time synchronous and the quality of distance training is still to be improved. Mobile phone live broadcast is a new remote real-time synchronous technology. It has the characteristics of very convenient, real-time synchronous and it can enhance the interaction. It can effectively improve the quality of distance training. In this paper, based on the analysis of relative research experiences, a strategy of k12 teachers’ distance training based on mobile phone live broadcast is designed, and then it is revised and perfected through action research; finally a six-dimensional strategy is formed, which includes task driven, resource-based learning, teaching guidance of solving technology problems, incentive mechanism promoting learning, mobile live interactive and evaluation and feedback. Meanwhile, the good application result is examined in teaching practice.

Throughout the history of world science and technology development, human society has experienced three industrial revolutions, marked by the emergence of steam engines, electrical appliances, and computers. Now, the world is undergoing the fourth industrial revolution. What is different from the past is that it is no longer marked by the invention and use of a certain technology, but covers multiple fields and is integrated and transcended, that is "artificial intelligence". This theme presents a diversified state in the research field. The main research contents are the influence of artificial intelligence subject rights and artificial intelligence on domestic and foreign politics. The main research methods are empirical research, normative research, comparative analysis and case analysis. In the future, it must be a tendency that more and more scholars prefer to doing quantitative research. In response to this field, researchers generally believe that the impact of artificial intelligence on today's society and the future society should be viewed dialectically, so as to prevent the shortcomings in advance and enable artificial intelligence to better serve the society.

The academic database market is dominated by a few publishers, and it is difficult for new publishers to develop new markets, which leads to monopoly in the academic database market. This paper describes four issues of academic database monopoly, which are the irrationality of database pricing, the abuse of database permissions, the concentration of operators and the restriction on users, and proposes to deal with database monopoly through open access, library association and legislative protection.

As the capacity of USB flash disk continues to increase, more and more laboratory managers no longer use the traditional CD to install the operating system, but use USB flash disk with Win PE to install, backup and restore the operating system. Win PE systems commonly used in the market include bigbaicai, laomaotao, IT sky and so on. Although these Win PE systems are simple and easy to use, they all have problems such as tampering with IE home page and stealing extra software, even some Win PE systems automatically load trojans and other programs after the system is installed. These problems seriously affect the security and stability of computer system. This article produces the Windows 10 PE system based on Microsoft's official Windows ADK.
