  • Sistema de notificação e extensão da plataforma WISE-MUSE
    Publication . Santos, João Paulo Brito Faria; Peralta, Laura Margarita Rodríguez
    A integração de sensores em estruturas, máquinas e ambientes, juntamente com uma eficiente recolha e envio de informação, trazem elevados benefícios para as sociedades actuais. Nesse sentido, com a crescente importância que as redes sem fios (WSN) assumem no contexto da qualidade de vida dos indivíduos, principalmente ao nível das comunicações, é fundamental procedermos à exploração das suas diversas potencialidades nos mais variados âmbitos. Deste modo, as WSN podem ser aplicadas em diversas áreas: saúde, monitorização ambiental, segurança de edifícios, indústria, monitorização de tráfego, monitorização de terramotos ou outras catástrofes naturais. Assim surge o projecto WISE-MUSE (Environmental Monitoring based on Wireless Sensor Networks for conservation of artwork and historical archives), que visa a implementação de um conjunto de soluções que permitem a monitorização contínua e automática de parâmetros ambientais (luminosidade, humidade, temperatura e CO2) através de WSN em museus. Este projecto de Mestrado em Engenharia Informática situa-se no âmbito deste projecto WISE-MUSE e tem como intuito: (i) a extensão da plataforma de monitorização de modo a recolher os dados das portas de emergência; (ii) a implementação de um sistema de notificações e alarmes via SMS e E-mail; e (iii) o desenvolvimento da plataforma Web WISE-MUSE, que permita a visualização remota dos dados dos sensores e das portas de uma forma integrada e em tempo real.

  • Touch ‘n’ sketch: pen and fingers on a multi-touch sketch application for tablet PC’s
    Publication . Vieira, Hugo David Jesus; Leeuwen, Josef Petrus van; Nóbrega, Leonel Domingos Telo
    In many creative and technical areas, professionals make use of paper sketches for developing and expressing concepts and models. Paper offers an almost constraint free environment where they have as much freedom to express themselves as they need. However, paper does have some disadvantages, such as size and not being able to manipulate the content (other than remove it or scratch it), which can be overcome by creating systems that can offer the same freedom people have from paper but none of the disadvantages and limitations. Only in recent years has the technology become massively available that allows doing precisely that, with the development in touch‐sensitive screens that also have the ability to interact with a stylus. In this project a prototype was created with the objective of finding a set of the most useful and usable interactions, which are composed of combinations of multi‐touch and pen. The project selected Computer Aided Software Engineering (CASE) tools as its application domain, because it addresses a solid and well‐defined discipline with still sufficient room for new developments. This was the result from the area research conducted to find an application domain, which involved analyzing sketching tools from several possible areas and domains. User studies were conducted using Model Driven Inquiry (MDI) to have a better understanding of the human sketch creation activities and concepts devised. Then the prototype was implemented, through which it was possible to execute user evaluations of the interaction concepts created. Results validated most interactions, in the face of limited testing only being possible at the time. Users had more problems using the pen, however handwriting and ink recognition were very effective, and users quickly learned the manipulations and gestures from the Natural User Interface (NUI).
