Feasibility of 3D body tracking from monocular 2D video feeds in musculoskeleta...
Clemente, Carolina; Chambel, Gonçalo; Silva, Diogo C. F.; Montes, António Mesquita; Pinto, Joana F.; Silva, Hugo Plácido da; Mesquita Montes, AntónioMusculoskeletal conditions affect millions of people globally; however, conventional treatments pose challenges concerning price, accessibility, and convenience. Many telerehabilitation solutions offer an engaging alternative but rely on complex hardware for body tracking. This work explores the feasibility of a model for 3D Human Pose Estimation (HPE) from monocular 2D videos (MediaPipe Pose) in a physiotherap...
e-CoVig: a novel mHealth system for remote monitoring of symptoms in COVID-19
Raposo, Afonso; Marques, Luis; Correia, Rafael; Melo, Francisco; Valente, João; Pereira, Telmo; Rosario, Luis; Froes, Filipe; Sanches, JoãoIn 2019, a new virus, SARS-CoV-2, responsible for the COVID-19 disease, was discovered. Asymptomatic and mildly symptomatic patients were forced to quarantine and closely monitor their symptoms and vital signs, most of the time at home. This paper describes e-CoVig, a novel mHealth application, developed as an alternative to the current monitoring paradigm, where the patients are followed up by direct phone con...
Applications and Issues for physiological computing systems: an introduction to...
Fairclough, Stephen; Silva, Hugo Plácido da; Gamboa, Hugo; Gilleade, Kiel; Bermúdez i Badia, SergiThe prospect of connecting the brain and body to a technological device can elicit a broad range of responses from potential users. Early adopters are thrilled by the possibility of a device that can interface directly to the human nervous system. For the vast majority, interest is tempered by caution, as nascent varieties of physiological computing systems raise as many questions as answers about how we will i...
Off-the-person electrocardiography: performance assessment and clinical correla...
Silva, Hugo Plácido da; Carreiras, Carlos; Lourenço, André Ribeiro; Fred, Ana; Neves, Rui César das; Ferreira, RuiPrevious work by our group introduced a novel concept and sensor design for “off-the-person” ECG, for which evidence on how it compares against standard clinical-grade equipment has been largely missing. Our objectives with this work are to characterise the off-the-person approach in light of the current ECG systems landscape, and assess how the signals acquired using this simplified setup compare with clinical...
A web-based platform for biosignal visualization and annotation
Lourenço, André Ribeiro; Silva, Hugo Plácido da; Carreiras, Carlos; Alves, Ana Priscila; Fred, Ana Luísa NobreWith the advent of wearable sensing and mobile technologies, biosignals have seen an increasingly growing number of application areas, leading to the collection of large volumes of data. One of the difficulties in dealing with these data sets, and in the development of automated machine learning systems which use them as input, is the lack of reliable ground truth information. In this paper we present a new web...
Check your biosignals here: a new dataset for off-person ECG biometrics
Silva, Hugo Plácido da; Lourenço, André Ribeiro; Fred, Ana Luísa Nobre; Raposo, Nuno; Aires-de-Sousa, MartaThe Check Your Biosignals Here initiative (CYBHi) was developed as a way of creating a dataset and consistently repeatable acquisition framework, to further extend research in electrocardiographic (ECG) biometrics. In particular, our work targets the novel trend towards off-the-person data acquisition, which opens a broad new set of challenges and opportunities both for research and industry. While datasets wit...
Experimental Study And Evaluation Of Paper-Based Inkjet Electrodes For ECG Sign...
Alves, Ana Patrícia; Martins, João; Silva, Hugo Plácido da; Lourenço, André Ribeiro; Fred, Ana Luísa Nobre; Ferreira, HugoApplications involving biosignals, such as Electrocardiography (ECG), are becoming more pervasive with the extension towards non-intrusive scenarios helping targeting ambulatory healthcare monitoring, emotion assessment, among many others. In this study we introduce a new type of silver/silver chloride (Ag/AgCl) electrodes based on a paper substrate and produced using an inkjet printing technique. This type of ...
BITalino: a novel hardware framework for physiological computing
Silva, Hugo Plácido da; Guerreiro, J.; Lourenço, André Ribeiro; Fred, Ana Luísa Nobre; Martins, RaúlPhysical computing has spun a true global revolution in the way in which the digital interfaces with the real world. From bicycle jackets with turn signal lights to twitter-controlled christmas trees, the Do-it-Yourself (DiY) hardware movement has been driving endless innovations and stimulating an age of creative engineering. This ongoing (r)evolution has been led by popular electronics platforms such as the A...
BIT: Biosignal Igniter Toolkit
Silva, Hugo Plácido da; Lourenço, André Ribeiro; Fred, Ana; Martins, RaúlThe study of biosignals has had a transforming role in multiple aspects of our society, which go well beyond the health sciences domains to which they were traditionally associated with. While biomedical engineering is a classical discipline where the topic is amply covered, today biosignals are a matter of interest for students, researchers and hobbyists in areas including computer science, informatics, electr...
ECG Biometrics: A Template Selection Approach
Lourenço, André Ribeiro; Carreiras, Carlos; Silva, Hugo Plácido da; Fred, Ana Luísa NobreElectrocardiography (ECG) biometrics is emerging as a viable biometric trait. Recent developments at the sensor level have shown the feasibility of performing signal acquisition at the fingers and hand palms, using one-lead sensor technology and dry electrodes. These new locations lead to ECG signals with lower signal to noise ratio and more prone to noise artifacts; the heart rate variability is another of the...
