    Explaining COVID-19 contagion in Portuguese municipalities using spatial autocorrelation models
    2021-04 - Mourao, Paulo; Bento, Ricardo Jorge e Silva
    This paper investigates the pattern of COVID-19 contagion in Portuguese municipalities from March 23rd to April 5th (the exponential phase). We have recurred to spatial autocorrelation models to discuss how the conglomeration of highly infectious spaces has also contributed to infecting neighbouring municipalities. We have used several indicators for the contagion of COVID-19 from the number of infectious individuals to rates of infectious. As explicative variables, additionally to spatial proximity, we also considered population density, the share of the elderly population as well as the length of municipal perimeter/border. Our results show that highly dense municipalities tended to contaminate close areas. Lengthier perimeters also showed a positive effect on the contagious indicators for a given municipality.

    AccessWeb Barometer - A Web Accessibility Evaluation and Analysis Platform
    2015 - Ramiro, Gonçalves; José, Martins; Jorge, Pereira; Carlos, Peixoto; Tânia, Rocha; Branco, Frederico
    The constant evolution of all Web related technologies, and the considerable adoption of these technologies in our society’s everyday life, has brought to the discussion table the ability of these Web technologies and Web contents to become accessible to all, including those with some sort of disability. During the past years, a research project has been executed in order to, not only give the Web accessibility topic more visibility within our society, but also to achieve indicators on the levels of accessibility presented by privately held company websites. Considering the growing need to rapidly achieve Web accessibility indicators, whose complexity has significantly increased, the research team inherent to the referred project developed a software platform, entitled “AccessWeb Barometer”, that has the ability to perform Web accessibility evaluations to multiple websites in simultaneous. It also has the ability to analyze and publish the results inherent to those evaluations, and to allow its users to create their own analysis and dashboards. In this paper, we present the AccessWeb Barometer software platform architecture, its overall characterization and validation, and also the possibilities of what a platform like this can bring to Web content developers and to organizations worldwide.

    USABILITY EVALUATION OF THE TOUCH SCREEN AND MOUSE AS INPUT DEVICES BY PEOPLE WITH INTELLECTUAL DISABILITIES
    2015 - Tânia, Rocha; Diana, Carvalho; Ramiro, Gonçalves; José, Martins; Frederico, Branco; Maximino, Bessa
    With this study we aim to assess if the touch screen input device can be a more usable option for digital interaction by people with intellectual disabilities, when compared to a traditional mouse input. In previous studies, we observed that many users with intellectual disabilities struggle to interact with digital content when using traditional input devices, such as the keyboard or mouse. This can lead to a decrease in their motivation to access digital content. Therefore, it is important to evaluate other options, such as touch screens, in order to present a more usable option of interaction for this specific group. For that, we present a case study where the participants were invited to perform primitive selection tasks in a colouring activity, using a painting Web application. The results showed that this group presented a better performance and made less errors when interacting with the touch screen, rather than when compared with the traditional mouse input. We also registered an increase regarding their motivation and satisfaction, when using the touch screen as the input device.
