Research on the Specificity of the Handwriting Tablet in Electronic Handwriting
Different from paper-based handwriting,electronic handwriting is susceptible to interference from the handwriting tablet,making it necessary to distinguish whether its characteristics are due to hu-man writing habits or specificity of the writing tablet.In the experiment,three kinds of handwriting char-acteristics including initial stroke,final stroke and stroke marks were selected as the research objects,which are of high identification value but easily influenced by writing tools and media.Three representa-tive writing tablets with distinct parameters were used as the experimental devices and the strokes were u-tilized as the observation perspective to conduct qualitative and quantitative analysis of the characteristics of electronic handwriting.The results showed that the characteristics of initial strokes,final strokes,and stroke marks on different writing tablets exhibited special forms,and specific feature types presented by the tendencies significantly varied,which together constituted the specific reflection of handwriting tablet and confirmed the writing tablet would interfere with the reflection of writing actions.Therefore,in the i-dentification of electronic handwriting,it is essential to avoid considering the specificity of the writing tab-let as human writing habits,but rather to view them as non-essential difference.Eliminating the interfer-ence of specificity of the handwriting tablet in electronic handwriting is conductive to improve the accura-cy of handwriting identification.
