• Abstract: The purpose of this study is to explore the changes of signature handwriting characteristics of electronic writing instruments and writing carriers under different writing conditions, and to explore the relationship between the characteristics of electronic handwriting and paper handwriting, so as to provide a scientific basis for the identification of signature handwriting. Using a capacitive touch screen and stylus, the electronic signature handwriting of 30 volunteers was used as the research object, and 6 consecutive writing sessions were collected respectively. Slow, normal, and fast writing; Electronic signature handwriting for seated and standing writing. The handwriting characteristics of signatures on traditional paper carriers were compared with those of the traditional paper carriers, and the variation rules of handwriting features, layout features, and pen movement characteristics were analyzed. The results showed that the handwriting characteristics of electronic signatures will be affected by the proficiency of use, and the characteristics of electronic signatures written in unfamiliar situations are significantly different from those of paper signatures. When the writing speed changes, the changes of electronic signatures in terms of general characteristics and pen movement characteristics are similar to those of paper signatures, but they are different in layout characteristics. When the writing posture changes, the general characteristics and layout characteristics are similar to those of paper signatures, but the characteristics of pen movement are different. 本研究旨在探究电子书写工具和书写载体在不同书写条件下签名笔迹特征变化的规律，探寻电子笔迹与纸质笔迹特征之间的联系，为签名笔迹的鉴定提供科学依据。使用电容式手触屏和手写笔，以30名志愿者的电子签名笔迹为研究对象，分别采集6次连续书写，慢速、常速和快速书写，以及坐姿和站姿书写的电子签名笔迹，并与传统纸质载体上的签名笔迹特征进行比对，分析笔迹概貌特征、布局特征、运笔特征的变化规律。结果显示，电子签名笔迹特征受使用熟练程度的影响，在不熟悉的情况下所书写的电子签名与纸质签名特征变化差别明显；书写速度改变时，电子签名在概貌特征和运笔特征方面变化与纸质签名接近，但在布局特征上却体现不同；而书写姿势变化时，概貌特征和布局特征方面与纸质签名相近，但运笔特征又有所不同。
