Although AR already exists, it has a lot of space for improvement. AR can seamlessly integrate real-world information with virtual world information. It is a kind of physical information that is difficult to experience in a certain time and space of the real world, such as visual information, sound, taste, and touch. Through computer and other science and technology, simulation and then superimposition, the virtual information is applied to the real world, perceived by human senses, to achieve a sensory experience beyond reality. The real environment and virtual objects are superimposed in real time on the same picture or space. The AR not only displays the information of the real world, but also displays the virtual information at the same time, and the two kinds of information complement each other and superimpose. In visual augmented reality, users can use the helmet display to combine the real world with computer graphics to see the real world around it. AR includes new technolog

What I want to contribute to Wiki is to provide more knowledge about web design. Because it's something I'm more interested in and related to my major. Learning to do web design requires knowing how to use HTML, CSS, and JavaScript. Wiki mentions HTML but doesn't mention CSS or JavaScript, so I want to add some knowledge about it. CSS controls the display style of web page pictures, tables, text, etc. in front of us, such as color, border, size and so on. At present, the latest version of CSS is CSS3, which is a style design language that can truly achieve the separation of web page presentation and content. Compared with the performance of traditional HTML, CSS can precisely control the position and layout of objects in the web page at the pixel level, support almost all font size styles, have the ability to edit web objects and model styles, and can carry out the preliminary interactive design. It is the best performance design language based on text display at presen

As we know today, software piracy and file sharing existed before the advent of the Internet, mainly through message boards and private sites. File sharing means that the system allows multiple users to use one or some files together but finding files is tedious and downloading them is slower. It is more common to use a friend's software or music repair as a physical copy. P2P file sharing has changed all this, and people can directly access other people's shared data. P2P is a completely different model, and everyone becomes a server. It has no central server, so everyone who uses the network acts as their own server. P2P makes it a two-way street, rather than simply taking files. In modern P2P networks, when more users download files, it is faster. Instead of getting the entire file from one user, you get smaller files from hundreds or thousands of other users. Even if they only bring you a little bandwidth, composite connections mean that you can get the maximum speed. The

Privacy is a way to protect oneself from the actions of others or organizations. Privacy carries the connotation of domination and restricted access. Individuals should be allowed to control the people who may have certain kinds of information and the context in which it appears. Information as privacy does not mean that it will never appear in the public's vision but refers to the traditional understanding that individuals can control whether their information is open to others and the extent and extent of its openness. Privacy is a secret that is unwilling or inconvenient to inform others, including the privacy of private information from other people's illegal collection, penetration, and the public, private life. With the emergence of new communication channels brought about by emerging media, personal privacy is easy to be found by others. For example, basic personal information, including name, sex, age, education, marital status, family members ID card number and other
