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 ... -
Mood state detection in handwritten tasks using PCA–mFCBF and automated machine learning
(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 ... -
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 ... -
On the analysis of speech and disfluencies for automatic detection of Mild Cognitive Impairment
(Neural Computing and Applications. 2020;32:15761–15769, 2018-05-08)Alzheimer’s disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the so-called Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this ... -
Quantitative analysis of relationship between hypokinetic dysarthria and the freezing of gait in Parkinson’s disease
(Cognitive Computation. 2018;10(6):1006-1018, 2018)Hypokinetic dysarthria (HD) and freezing of gait (FOG) are both axial symptoms that occur in patients with Parkinson’s disease (PD). It is assumed they have some common pathophysiological mechanisms and ... -
Reliability and validity of the Polar V800 sports watch for estimating vertical jump height
(Journal of Sports Science and Medicine. 2021;(20):149-157, 2021)This study aimed to assess the reliability and validity of the Polar V800 to measure vertical jump height. Twenty-two physically active healthy men (age: 22.89 ± 4.23 years; body mass: 70.74 ± 8.04 kg; ...
