Lattice book interaction method

Abstract

The embodiment of the invention discloses a lattice book interaction method, which belongs to the technical field of intelligent pens, and comprises the following steps that: before writing, a user clicks an envelope page by using an intelligent pen, a first dot matrix code is laid on a part and the whole page of the envelope page, and the intelligent pen analyzes binary information, namely envelope code information, carried by the intelligent pen through lens imaging and sends the binary information to an intelligent terminal; the intelligent terminal matches the envelope code information with a background database to obtain note information corresponding to the envelope code; the intelligent pen writes on the inner page of the dot matrix book, a second lattice code is laid on the inner page of the dot matrix book, and in the inner page writing process of the intelligent pen, sends coordinate information of recognized writing points to the intelligent terminal; and the intelligent terminal draws the writing point in the note information page corresponding to the envelope code according to the page number and the coordinate information of the writing point. Through the method of the invention, effective identification can be carried out based on different writing pages of the intelligent pen.

Description

technical field [0001] The invention relates to the technical field of smart pens, in particular to a dot matrix interaction method. Background technique [0002] Writing is a wonderful experience. Writing on paper always has a charm. Even in the information age, people are always eager to save handwritten notes. Especially in terms of smart education, when black technologies such as electromagnetic writing recognition, infrared dot matrix recognition, and ultrasonic recognition are integrated into writing, there will be a variety of smart writing pens. [0003] In the prior art, dot-matrix notebooks can be divided into Chinese texts, composition texts, mathematics books, English books, diaries, etc. according to subject types or uses, and dot-matrix notebooks of the same type are printed with the same code points. Notebooks are consumables, and the same type of notebooks may be used by the same user several times. Therefore, users cannot distinguish between them when using...
