NetEase Youdao, China's largest online education brand in terms of number of users, unveiled a series of products on Tuesday, as part of its accelerated push into the online education sector for children in K12, or kindergarten to 12th grade.

The online education subsidiary of tech giant NetEase Inc launched its latest e-dictionary pen on Tuesday, which allows students to find out meanings of words through scanning.

With an average accuracy rate of 95.5 percent, the upgraded product will enable users to search 60 words per minute, which, according to the firm, is five times faster than that of e-dictionary.

Zhou Feng, CEO of NetEase Youdao, said with the new products, the firm aims to leverage technologies including artificial intelligence to step up the commercialization of advanced technologies in the education industry.

NetEase, as China's second-largest gaming publisher, merged earlier this year with its education unit in Hangzhou into NetEase Youdao. The unit in Hangzhou used to cover business including online career education, online coding courses and massive open online courses.

On Tuesday, NetEase Youdao also unveiled another four online learning tools for children and teenagers, focused on mathematics, English, reading and coding.
