Advanced parametrization of graphomotor difficulties in school-aged children
(IEEE Acces. 2020 Jun 17;8:112883-112897, 2020-06-17)School-aged children spend 31–60% of their time at school performing handwriting, which is a complex perceptual-motor skill composed of a coordinated combination of fine graphomotor movements. As up to ... -
Analysis of gender differences in online handwriting signals for enhancing e-health and e-security applications
(Cognitive Computations. 2023;15:208-219, 2023)Handwriting is a complex perceptual–motor skill that is mastered around the age of 8. Although its computerized analysis has been utilized in many biometric and digital health applications, the possible ... -
Analysis of various fractional order derivatives approaches in assessment of graphomotor difficulties
(IEEE Access. 2020 Dec 4; 8:218234-218244, 2020-12-04)Graphomotor disabilities (GD) are present in up to 30% of school-aged children and are associated with several symptoms in the field of kinematics. Although the basic kinematic features such as velocity, ... -
Exploiting spectral and cepstral handwriting features on diagnosing Parkinson’s disease
(IEEE Access. 2021 Oct 22;(9):141599-141610, 2021-10-22)Parkinson’s disease (PD) is the second most frequent neurodegenerative disease associated with several motor symptoms, including alterations in handwriting, also known as PD dysgraphia. Several computerized ... -
Handwriting biometrics: applications and future trends in e-security and e-health
(Cognitive Computation. 2020;12;940–953, 2020)Online handwritten analysis presents many applications in e-security, signature biometrics being the most popular but not the only one. Handwriting analysis also has an important set of applications in ... -
Identification and monitoring of Parkinson’s disease dysgraphia based on fractional-order derivatives of online handwriting
(Applied Sciences. 2018;8(12):2566, 2018-12-11)Parkinson’s disease dysgraphia affects the majority of Parkinson’s disease (PD) patients and is the result of handwriting abnormalities mainly caused by motor dysfunctions. Several effective approaches ... -
On handwriting pressure normalization for interoperability of different acquisition stylus
(IEEE Access. 2021 Jan 21;9:18443-18453, 2021-01-21)In this paper, we present a pressure characterization and normalization procedure for online handwritten acquisition. Normalization process has been tested in biometric recognition experiments (identification ... -
Online handwriting, signature and touch dynamics: tasks and potential applications in the field of security and health
(Cognitive Computation. 2021 Oct 1;13:1406-1421, 2021-10-01)Advantageous property of behavioural signals (e.g. handwriting), in contrast to morphological ones (e.g. iris, fingerprint, hand geometry), is the possibility to ask a user to perform many different ...
