A method for acquiring handwriting information

Abstract

The invention provides a method for obtaining handwriting information. In the method, a five-dimensional force / moment sensor module, an embedded microprocessor module and a true-color display module which are arranged in a handwriting device are utilized. The method comprises the following steps of: firstly initializing the five-dimensional force / moment sensor module, wherein the initialization comprises power supplying, zero-point modifying and interface drive requirement and temperature compensating; acquiring numerical values output by the five-dimensional force / moment sensor, thus obtaining five-dimensional force handwriting force data; performing decoupling operation on the five-dimensional force handwriting force data, thus obtaining real-time three-dimensional handwriting vector information numerical values and two-dimensional handwriting moment vector information numerical values; and performing corresponding formula calculation, thus obtaining real-time two-dimensional handwriting coordinate information and obtaining complete handwriting information. The method can be used for solving the problems that the handwriting information cannot be completely obtained in the existing handwriting information obtaining method, therefore, the security of signature information is improved, and the method provides a new guarantee means for ensuring the information security of important document signing in e-government or contract signing in e-business, and the like.

Description

technical field [0001] The invention relates to the fields of computer information and automation electronics, in particular to a method for acquiring handwritten handwriting information, which can be applied to occasions where digital signature verification is required in the field of information security. Background technique [0002] With the continuous development of computer technology, office automation and paperless office have become the main work forms in e-commerce and e-government. Through office automation and paperless office, people can conveniently use computers to process various documents and office work without using physical paper, thereby reducing the consumption rate of paper. [0003] However, from the perspective of information confidentiality, in order to ensure the security of important office documents, especially the issuance of legally binding documents, such as the signing of large trade contracts, it is still unreliable to rely solely on compute...

Problems solved by technology

[0009] In the prior art, the identification of handwriting information is only based on two-dimensional static coordinate information, or relying on third-party equipment to assist in identifying handwriting information, such as using handwriting similarity, handwriting fusion of physiological characteristics of mixed fingerprints or palmprints, etc., and This will undoubtedly increase the complexity of handwriting recognition, especially, increase the complexity of handwriting information acquisition, often bring instability to system applications
