  • 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)
    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 ...
  • Mood state detection in handwritten tasks using PCA–mFCBF and automated machine learning 

    Nolazco Flores, Juan Arturo; Faundez-Zanuy, Marcos; Velázquez-Flores, O. A.; Del-Valle-Soto, Carolina; Cordasco, Gennaro; Esposito, Anna (Sensors. 2022 Feb 21;22(4):1686, 2022 Feb 2)
    In this research, we analyse data obtained from sensors when a user handwrites or draws on a tablet to detect whether the user is in a specific mood state. First, we calculated the features based on the ...
  • 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 ...
  • Emotional state recognition performance improvement on a handwriting and drawing task 

    Nolazco Flores, Juan Arturo; Faundez-Zanuy, Marcos; Velázquez-Flores, O. A.; Cordasco, Gennaro; Esposito, Anna (IEEE Access. 2021 Feb 23;(9):28496-28504, 2021-02-21)
    In this work we combine time, spectral and cepstral features of the signal captured in a tablet to characterize depression, anxiety, and stress emotional state recognition on the EMOTHAW database. EMOTHAW ...
  • Analysis of fine motor skills in essential tremor: combining neuroimaging and handwriting biomarkers for early management 

    López-de-Ipiña, Karmele; Solé-Casals, Jordi; Sánchez-Méndez, José Ignacio; Romero-Garcia, Rafael; Fernandez, Elsa; Requejo, C.; Poologaindran, Anujan; Faundez-Zanuy, Marcos; Marti Masso, Jose Felix; Bergareche, Alberto; Suckling, John (Frontiers in Human Neuroscience. 2021 Jun 8;15:648573, 2021-06-08)
    Essential tremor (ET) is a highly prevalent neurological disorder characterized by actioninduced tremors involving the hand, voice, head, and/or face. Importantly, hand tremor is present in nearly all ...
