The predecessor of the Erbi input method is the "Yin-Yang Bipolar Phonetic Code Input System". It is a phonetic input method invented by Mr. Chen Jinsong in 1992 and obtained a national patent in 1996. Gao Jinglian acquired the patent in 1998, renamed the "Yin-Yang Code" as the "Erbi Input Method" in 1999, and established Guangdong Erbi Software Co., Ltd. in Guangzhou in January 2000. Erbi Company optimized the original Yin and Yang codes and launched the Erbi input method software to the outside world for the first time in early 2000. Since then, the Erbi input method has officially appeared in the public eye.
In May 2000, the research group "Research on the Social Benefits of Chinese Character 'Two-stroke Input Method'" chaired by Li Yining, a member of the Standing Committee of the National People's Congress, a famous economist, and a professor at Peking University, and participated by many experts and scholars, conducted a formal study. Report.
In July 2000, it was chaired by Professor Tao Xiping, Chairman of the National Federation of UNESCO Associations, with members of the National People’s Congress Zhu Xiangyuan, Chen Junliang, Mao Daru, Professor Shao Weizhong of Peking University, and members of the National Language Working Committee A jury composed of nine experts including Li Xingjian provided review opinions on the topic of "Research on Social Benefits of Chinese Character 'Two-stroke Input Method'". The evaluation committee agreed with the report of the research team and also recommended that the National Ministry of Education organize experts to comprehensively evaluate the two-stroke input method.
In September 2000, the Basic Education Textbook Development Center of the Ministry of Education established a project to conduct research on the teaching of the "Two-stroke Input Method". In November of that year, the Ministry of Education conducted a preliminary evaluation of the "Two-stroke Input Method". In December 2000, the "Two-stroke Input Method", which was modified and standardized by experts from Beijing Normal University, passed the re-evaluation by the Ministry of Education. The re-evaluation believes that the modified "Two-stroke Input Method" can be used in the teaching field of primary and secondary schools. The "Erbi Input Method" has become the only input method that has passed the review of the Basic Education Curriculum and Textbook Development Center of the Ministry of Education and been approved to be included in the basic textbooks of primary and secondary schools.
In April 2002, Erbi input method software was the only one to pass the national standard certification. On May 15, 2002, Erbi Input Method passed the CESI national certification for Chinese information technology products. This certification was technically supported by the Information Processing Product Standard Compliance Testing Center (CTC) test report. The Erbi input method became the first Chinese character keyboard input system to pass national certification at home and abroad.
Although the Erbi input method has received a lot of praise and honors, because Guangdong Erbi Software Co., Ltd. sold the Erbi input method software at a high price, and the intelligent ABC input method and Wubi input method were already widely used at that time. It is a free product, and only few people are willing to try Erbi. In the end, Guangdong Erbi Software Co., Ltd., which mainly engaged in Erbi input method software, was on the verge of bankruptcy. On July 22, 2004, the related patents of Erbi were sold to Zhuhai Yingchuang Technology Development Co., Ltd. However, Zhuhai Yingchuang Technology Company, which later held the second patent, did not commercially promote the second patent, nor did it conduct subsequent development and maintenance. As of January 1, 2013, the two-stroke input method invention patent has reached the 20th anniversary since the application date. After the expiration of the patent validity period, the two-stroke input method encoding technology has become the public wealth of society, and any unit or individual can use it free of charge. to use.
On the other hand, the Erbi input method has attracted many Erbi enthusiasts with its excellent features. Some enthusiasts have further improved and optimized the Erbi input method, and at the same time made improvements to the Erbi input method software. maintain. Most Erbi input method software can be obtained and used for free on the Internet. The coding ideas of the two-stroke input method have also been used for reference by many other new input methods, especially the positioning idea of ??two-stroke connected two strokes, which is reflected in many new shape code input methods. For example, some enthusiasts are fond of the five-stroke input method. For revision and optimization, the two-stroke connected positioning method is used, which greatly enhances the regularity and memorability of the root layout of this type of input method.
