Research On The Law Of Chinese Handwriting Identification On Touchs Creen--taking Signature Handwriting As An Example

The appearance of handwriting on the touch screen poses new challenges for handwriting identification.This article discusses touch screen signature handwriting from traditional signature handwriting,combs the concept of touch screen signature,and analyzes the related concepts of touch screen signature,distinguishing touch screen signature and digital handwriting signature,touch screen signature and electronic signature handwriting,touch screen signature and digital Related concepts such as signatures.After sorting out the concepts,this paper conducts an empirical study on the characteristics of static handwriting in the handwriting of the touch screen signature,and summarizes the changes in the signature authentication of the touch screen.Compared with the traditional handwriting tools to test the formation of handwriting,the formation mechanism and writing conditions of touch screen handwriting have changed significantly.This change has resulted in a significant change in handwriting characteristics.In this paper,10 adults are randomly selected as the object of sample extraction.First,each writer is required to write his signature 10 times on the paper with a black marker,apple pencil 10 times on the ipad,and fingers on the ipad Write 10 times,write your own signature on the Huawei tablet 10 times with these four ways to sign,repeat five times,each person has a total of 200 signatures,and there are 500 signature handwriting samples in each way;Then,the collected sample handwriting is divided into three groups,A,B,and C.Group A represents the signature written on paper by the black marker and the signature written on the iPad by the stylus.Group B represents the finger on the excellent screen(ipad)The signature written on the second-level screen(Huawei)is compared with the signature written on the second-level screen(Huawei).Group C represents the signature written on the iPad by the stylus and the signature written on the iPad by the finger;The three sets of data were observed,compared and analyzed from the aspects of writing style features,layout features,writing features,structural features,stroke order features,and pen movement features.The handwriting feature change rate was calculated,and the three groups of handwriting samples were compared horizontally;finally Summarizes the characteristics of the touch screen signature handwriting changes.In the analysis of the data of these experimental samples,the focus is on summarizing the common handwriting between the handwriting on the touch screen and the traditional handwriting,the handwriting on the different touch screens,and the handwriting on the same touch screen between the fingers and stylus of different writing tools Analysis of points and differences,as well as the magnitude and possible causes of the difference.It is expected to provide theoretical reference and practical reference for the identification of touch screen signature handwriting.This article is divided into four parts:Part Ⅰ:an overview.It mainly introduces the necessity and problems of handwriting to touch screen handwriting,the identification of touch screen handwriting and the basic theory of identification.Part Ⅱ:experimental design and statistical method.Mainly introduce the experimental object,experimental preparation and statistical methods.Part Ⅲ:statistical analysis of data results.According to the observation and analysis of each group of experimental sample handwriting,the signature handwriting of the same person’s different writing methods is compared,the statistical analysis is carried out,the stable characteristic,the relative stability characteristic and the change rate of the characteristic are summarized,and the horizontal comparative analysis is carried out from the aspects of writing style characteristic,layout characteristic,writing method characteristic,structure characteristic,stroke sequence characteristic,moving pen characteristic and so on.Part Ⅳ:the value analysis of the signature handwriting features of electronic handwritten board.enrich and perfect the theoretical basis of handwriting identification.
