Force feedback, electronic signature handwriting, dynamic features, forged signatures
This paper investigates the dynamic characteristics related to the writing duration, pressure, and velocity of handwriting using a haptic device with force feedback for electronic signature and data acquisition. A spring–damper mechanics model is used to describe the forces exerted during the writing process, while a writable virtual paper plane is constructed to increase the genuineness of the writing process. The data of genuine and forged signature handwritings by volunteers were collected under natural writing conditions in a seated position, and the similarities and differences of dynamic characteristics between the stability of dynamic characteristics of electronic signature handwriting of the same person, and the forged and genuine electronic signature handwriting were also analysed. It was found that the dynamic characteristics of the electronic signature handwriting of the same person with tactile perception are quite stable, but they differ significantly between the forged and genuine signature handwriting. The study shows that using electronic devices with force feedback for electronic signature is more secure and reliable.
