    • Advanced parametrization of graphomotor difficulties in school-aged children 

      Galaz, Zoltan; Mucha, Ján; Zvončák, Vojtěch; Mekyska, Jiri; Smekal, Zdenek; Zvončáková, Katarína; Ondráčková, Anežka; Urbanek, Tomas; Havigerova, Jana Marie; Bednarova, Jirina; Faundez-Zanuy, Marcos (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 various fractional order derivatives approaches in assessment of graphomotor difficulties 

      Mucha, Ján; Mekyska, Jiri; Galaz, Zoltan; Faundez-Zanuy, Marcos; Zvončák, Vojtěch; Zvončáková, Katarína; Urbanek, Tomas; Havigerova, Jana Marie; Bednarova, Jirina; Smekal, Zdenek (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 

      Nolazco Flores, Juan Arturo; Faundez-Zanuy, Marcos; de la Cueva, Victor; Mekyska, Jiri (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 

      Faundez-Zanuy, Marcos; Fierrez, Julian; Ferrer, Miguel A; Diaz, Moises; Tolosana, Ruben; Plamondon, Réjean (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 

      Mucha, Ján; Mekyska, Jiri; Galaz, Zoltan; Faundez-Zanuy, Marcos; López-de-Ipiña, Karmele; Zvoncak, Vojtech; Kiska, Tomáš; Smekal, Zdenek; Brabenec, Lubos; Rektorova, Irena (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 

      Faundez-Zanuy, Marcos; Brotons-Rufes, Olga; Paul Recarens, Carles; Plamondon, Réjean (IEEE Access. 2021 Jan 21;9:18443-18453, 2021-01-21)
