- EureKiT em braille – jogo inclusivo para deficientes visuaisPublication . Oliveira, Mateus; Pereira, Ana I.; Fernandes, Florbela P.; Pacheco, Maria F.; Alves, Francisco M.A integração das pessoas com deficiência visual no mercado de trabalho e nos outros aspetos da vida em sociedade enfrenta obstáculos físicos e culturais que impedem a sua plena inclusão [1, 2]. O presente trabalho visa a inclusão de deficientes visuais em atividades lúdico-pedagógicas e o seu objetivo é adaptar um jogo de cartas concebido e desenvolvido no Instituto Politécnico de Bragança (IPB), o Eurekit. O Eurekit é jogado por dois ou mais jogadores e está organizado em 4 níveis de dificuldade. O jogo destina-se a pessoas com idade superior a 5 anos, os números e as cores dispostos nas cartas têm o intuito de familiarizar e estimular o raciocínio das crianças ajudando no processo de aprendizagem. O jogo Eurekit adaptado tem o intuito de promover a aprendizagem da mesma maneira que o jogo tradicional o faz, utilizando técnicas recentes para o ensino de invisuais. Os números são inseridos nas cartas em alto relevo e as cores são representadas através de figuras geométricas conhecidas, como triangulo, círculo, quadrado e combinações das geometrias citadas para demais cores

- Estratégias inclusivas para o ensino da matemática: projeto SMILDPublication . Pacheco, Maria F.; Pereira, Ana I.; Fernandes, Florbela P.As dificuldades de aprendizagem – gerais ou relacionadas com áreas cognitivas específicas – são manifestações frequentemente ligadas a fatores de risco, que podem ser de origem física ou sociocultural, que deverão ser abordados por meio de modelos de intervenção adequados e teoricamente fundamentados, com vistas a evitar o fracasso escolar. Os diferentes fatores de risco e seus efeitos são atribuíveis a alguns fatores de grande escala. Segundo inúmeras investigações internacionais (Abels; Hutman, 2015; Boyden; Dercon; Singh, 2015), o contexto sociocultural tem influência direta no desenvolvimento, podendo gerar atrasos significativos no desenvolvimento cognitivo desde os primeiros anos de vida. Na categoria dos alunos definida como de "baixo desempenho", as dificuldades são mais evidentes no campo linguístico, mas também são identificadas deficiências importantes na área da matemática (Geary; Hoard; Bailey, 2012).
- Overview of robotic based system for rehabilitation and healthcarePublication . Chellal, Arezki Abderrahim; Lima, José; Fernandes, Florbela P.; Gonçalves, José; Pacheco, Maria F.; Monteiro, Fernando C.As in many other fields, robots are increasingly being used in the healthcare sector, particularly for hospital logistics support, surgery and rehabilitation. Rehabilitation is a concern for millions of people around the world, and because of this, there has been a constant progress over the last decade in the rehabilitation robotics field, with the use of new technologies aimed at overcoming the different challenges faced in this field. In this sense, this paper reviews the main applications developed in the last ten years of rehabilitation robotics, as well as the different challenges that still need to be addressed in order to achieve the design of a prototype that is easy to use, small, safe, less costly and brings real added value to this field. Much of the efforts of the researchers in this topics is focused on providing as many DOF and ROM as possible, and also on the designing of new robots control algorithms
