[Chihiro Chihiro] As a small language learning software that includes more than 30 small languages, it combines listening, speaking, reading and writing to achieve the goal of completing all learning processes by downloading only one APP. The research significance of this APP is to solve the difficulty that specific groups want to learn small languages, but there is no suitable app in the market. At the same time, it is also committed to solving the problem that some groups want to learn different small languages and a large number of small languages, but need to download multiple apps at the same time. With an app, you can obtain learning resources in a variety of small languages and broaden your learning channels. The general idea of this APP is to provide convenience for users and create an APP with its own unique style. From the user's point of view is the fundamental method, on this basis, as wide as possible divergent thinking, consider user needs, to meet user needs. And make an app with your own design style. The research content is more than 30 small languages around the world. These small languages come from more than 200 countries and regions in the world, and have formed a set of language systems with local characteristics in the long history. The research content of this APP is to compile and classify these minor languages, and summarize a set of learning methods for each minor language. For example, English needs to learn from letters to learn phonetic symbols, while Japanese learns glyphs first. Each small language learning method needs a long time to summarize and explore, in order to meet the requirements of users to use electronic devices instead of looking for teachers offline. At the same time, the software will provide a variety of interesting services and links, enhance user interaction and experience, so that the user's learning is not boring. This needs to figure out and speculate on the user's psychological activities and value choices. From the user's point of view, predict what kind of thinking and reaction the user will have when opening a certain module, and reduce the user's boredom and resistance to the greatest extent. This is the scientific embodiment of this app in the user's psychology. It first provides users with correct and useful knowledge, increases the user's knowledge reserve, is conducive to the promotion of the cultural level of the whole people, and promotes the construction of a cultural society. At the same time, it can conform to the user's psychology and reduce the user's negative emotions. It is conducive to creating a positive learning atmosphere and a quiet social environment in the society. In addition, this software is characterized by school-enterprise cooperation with colleges and universities, and has teaching materials and open courses for major colleges and universities. With the social function of language learning, you can set up self-study rooms by adding friends to check each other's learning progress, share learning materials and achieve the effect of mutual supervision. The research method of this app is generally practical and pays attention to details. Practice, as the fundamental method of this app construction, has played a decisive role in the overall construction process. First of all, it is necessary to form an overall idea of app according to the internal structure of the brain. Secondly, it is necessary to judge whether each step is reasonable through specific practice, so as to make logical modifications. Secondly, in terms of layout design and page editing, it is necessary to judge whether the design style, each picture and each row of text conform to the specifications, are beautiful, and most importantly, whether they conform to the needs of users, adjustments and modifications are thus made. In terms of details, we should try our best to strive for perfection, pursue the beauty of every page and every plate, and do not make rough design. The theoretical basis of this app is the initial conditions of more than 30 minor languages from more than 200 countries in the world, as well as the increasing status of these minor languages in modern society and the increasingly extensive learning needs. The needs of these users make a society that can meet the needs of users, provide convenience for users, and develop these minor languages to more corners, The need to better preserve and continue the minor languages. The main technology is to use the common xd technology in the society for page design, ps technology for the production of each page and material, and the final realization of code programming technology. Only with these technologies can an app be changed from a design idea to a real object that users can download on their mobile phones.
