- Real-time blink detection as an indicator of computer vision syndrome in real-life settings: an exploratory studyPublication . Lapa, Inês; Ferreira, Simão; Mateus, Catarina; Rocha, Nuno; Rodrigues, MatildeWith the increase in the number of people using digital devices, complaints about eye and vision problems have been increasing, making the problem of computer vision syndrome (CVS) more serious. Accompanying the increase in CVS in occupational settings, new and unobstructive solutions to assess the risk of this syndrome are of paramount importance. This study aims, through an exploratory approach, to determine if blinking data, collected using a computer webcam, can be used as a reliable indicator for predicting CVS on a real-time basis, considering real-life settings. A total of 13 students participated in the data collection. A software that collected and recorded users’ physiological data through the computer’s camera was installed on the participants’ computers. The CVS-Q was applied to determine the subjects with CVS and its severity. The results showed a decrease in the blinking rate to about 9 to 17 per minute, and for each additional blink the CVS score lowered by 1.26. These data suggest that the decrease in blinking rate was directly associated with CVS. These results are important for allowing the development of a CVS real-time detection algorithm and a related recommendation system that provides interventions to promote health, well-being, and improved performance.
- Adaptação cultural e confiabilidade da versão portuguesa do Computer Vision Syndrome Questionnaire (CVS-Q)Publication . Rodrigues, Matilde; Mateus, CatarinaA Síndrome Visual de Computador (SVC) é caracterizada por um conjunto de sintomas visuais associados à utilização prolongada do computador. Instrumentos que permitam avaliar a SVC de uma forma simples e rápida são de particular importância, contudo não se verificou a existência de uma escala em português. A Computer Vision Syndrome Questionnaire (CVS-Q) é uma escala desenvolvida por Seguí et al.,e que avalia a frequência e a intensidade de 16 sintomas relacionados com a SVC.
- Effectiveness of an ergonomic intervention to reduce musculoskeletal discomfortPublication . Cardoso, Bárbara; Mateus, Catarina; Rodrigues, MatildeMusculoskeletal discomfort is common among office workers, being related to individual, workplace and behaviors risk factors. Ergonomic interventions are of particular importance to reduce musculoskeletal discomfort. However, only few have studied the impact of an ergonomic intervention on these symptoms reduction. This study aims to design and implement an intervention program to reduce musculoskeletal symptoms in office workers. A total of 84 employees from a charity and social assistance institution were involved in the study. The intervention included training actions to all employees, delivery of informative pamphlet and modifications in workplaces. To assess the intervention effectiveness, a questionnaire with a scale to assess musculoskeletal discomfort was applied in three moments: Pre-intervention; Post intervention Moment 1 and Post-intervention Moment 2. The areas described with greater musculoskeletal discomfort in the three moments were the neck, lower back, upper back and right shoulder. Between Pre-intervention and Post intervention Moment 1, there was a tendency to reduce musculoskeletal discomfort at the end of the day in all regions analyzed. It was also found a stagnation of discomfort in some regions of the body, comparing the Moment 1 and Moment 2 Post-intervention. Significant improvements in upper back and neck at the end of the workday were observed. This study suggests that an ergonomic intervention program has advantages for the employees' health, promoting the reduction of musculoskeletal symptoms
- Gamificação no Ensino Superior: experiências e potencialidades de jogos sérios e escape rooms no ensino em SaúdePublication . Araújo, André; Noites, Andreia; Salgado, Ana; Sequeiros, Miguel; Fonseca, Rosa; Pinto, Marta; Lopes, Ana; Simões-Silva, Vitor; Capitão, Susana; Mateus, Catarina; Rodrigues, MatildeNa área da Saúde as competências de raciocínio clínico, pensamento crítico e comunicação estão entre as mais valorizadas para a resolução de problemas e processos de tomada de decisão. Num mundo marcado pelo aumento da tecnologia, da comunicação à distância e pela desmaterialização de processos, o Ensino Superior depara-se com novos desafios. A gamificação é um dos processos pedagógicos que tem demonstrado elevado potencial em diversas áreas de conhecimento, nomeadamente na Saúde. Na ESS|P.Porto, instituição plural onde diversas especialidades de ciências e tecnologias da saúde crescem se cruzam há mais de 40 anos, diversas experiências têm vindo a ser partilhadas e expandidas no âmbito da atividade do Centro de Simulações da ESS-P.Porto (ESSim). Entre elas, destacam-se no âmbito da gamificação os jogos sérios e os escape rooms, que têm tido evoluções nos últimos anos.
- Síndrome Visual do Computador em trabalhadores de escritório: um estudo de casoPublication . Alves, Mónica; Pina, Ana; Mateus, Catarina; Rodrigues, MatildeThis study aims to characterize the Computer Vision Syndrome (CVS) among the office employees of a social solidarity institution. A total of 102 workers, aged between 20 and 63 years, were included. The CVS-Q questionnaire was used to identify workers with CVS. In addition, personal and work aspects were characterized, namely gender, age, pre-existing eye diseases, number of years and hours/day of work with computer. The results showed that of the total number of workers evaluated, 60.6% had CVS. A higher prevalence of CVS was observed among female. However, no relationship was observed between the remaining variables under study and the CVS. The results of this study emphasize the importance of an intervention program at CVS level, in order to promote behaviors among workers that reduce its prevalence.
- Ergonomic intervention program for office workers: a case study about its effect in computer vision syndrome and musculoskeletal discomfortPublication . Cardoso, Bárbara; Mateus, Catarina; Magalhães, Rúben; Rodrigues, MatildeThis study aims to develop and implement an ergonomic intervention program at the workplace of knowledge workers, and to evaluate its impact on the reduction of Computer Vision Syndrome (CVS) and musculoskeletal symptoms. 84 workers were part of the study (mean age 43.2 ± 9.7 years). The intervention included training, delivery of a packaging of artificial tears, and adjustments in workstations. It was conducted intensively along 6 weeks. Data was collected on-site, with questionnaires administered pre-intervention, 2 months after, and 4 months after. Participants exhibited behavioural changes, especially in workplace adjustments and visual rest. By the intervention’s end, over 90% had correctly adjusted screens and adopted appropriate postures, while 42.7% adhered to the 20x20x20 rule. CVS severity and prevalence decreased, but not significantly across the three time points. Significant improvements were observed in upper back and neck musculoskeletal symptoms at the end of workdays. Findings suggest that an ergonomic intervention program can benefit employees by reducing visual and musculoskeletal symptoms.
- Advancing the understanding of pupil size variation in occupational safety and health: A systematic review and evaluation of open-source methodologiesPublication . Ferreira, Filipa; Ferreira, Simão; Mateus, Catarina; Rocha, Nuno; Coelho, Luís; Rodrigues, MatildePupil size can be used as an important biomarker for occupational risks. In recent years, there has been an increase in the development of open-source tools dedicated to obtaining and measuring pupil diameter. However, it remains undetermined determined whether these tools are suitable for use in occupational settings. This study explores the significance of pupil size variation as a biomarker for occupational risks and evaluates existing open-source methods for potential use in both research and occupational settings, with the goal of to prevent occupational accidents and improve the health and performance of workers. To this end, a two-phase systematic literature review was conducted in the Web of Science™, ScienceDirect®, and Scopus® databases. For the relevance of monitoring pupil size variation in occupational settings, 15 articles were included. The articles were divided into three groups: mental workload, occupational stress, and mental fatigue. In most cases, pupil dilation increased with workload enhancement and with higher levels of stress. Regarding fatigue, it was noted that an increase in this condition corresponded with a decrease in pupil size. With respect to the open-source methodologies, 16 articles were identified, which were categorized into two groups: algorithms and software. Convolutional neural networks (CNN)1 have exhibited superior performance among the various algorithmic approaches studied. Building on this insight, and considering the evaluations of software options, MEYE emerges as the premier open-source system for deployment in occupational settings due to its compatibility with a standard computer webcam. This feature positions MEYE as a particularly practical tool for workers in stable environments, like those of developers and administrators.
