In order to meet the increasingly expanding character learning requirements of people, various translation learning machines such as a point reading machine, a point reading pen, a scanning pen, a tablet learning computer, a learning type mobile phone and the like are increasingly popular in the market. However, each of the above products has disadvantages.

The point reading machine is large in size and inconvenient to carry, and when the position of books is not placed accurately, the point reading machine is easy to misread.

The point-reading pen can only be applied to a special audio book printed with the invisible two-dimensional code, and a two-dimensional code and a compound data file corresponding to sound are required to be manufactured in advance. More importantly, the sound books must be carefully designed in advance, the area to be sounded and the corresponding sound are defined, and once the sound books are designed and printed, the sound books cannot be modified. When there is a mistake in the sound book, the publisher can only modify the book when the book is to be reprinted. This creates significant development costs and a huge backlog of money for both the manufacturer and the distributor.

Because the scanning pen must splice a string of tens or even hundreds of images, extract the middle line characters and straighten into a horizontal line, in the process, the phenomena of misspelling, miscutting, character skew and the like are inevitable, and further, the characters identified by OCR can not be avoided to be wrong. Moreover, the scanning pen has high requirements for users and environments, and if the scanning technique of the user is not standard or the paper image effect is not good, the error is increased.

For a tablet computer and a learning mobile phone, when a user reads a paper book and encounters a new word, the user must manually input each letter on the tablet computer or the mobile phone with the characters on the book before the user can obtain a paraphrase, and the efficiency of the operation process is low, so that the learning effect is influenced.
