- Figure follow: A step by step liberating devicePublication . Cavaleiro Rodrigues, José; Dias, Tiago; Silva, CatarinaFigure Follow (FF) is an award-winning project, envisioned to facilitate the learning of “Compulsory Figures”, an individual discipline of Artistic Roller Skating. This idea has now become a prototype under development, which uses sensors to detect the athletes position over figure lines, and provides, in real time, information concerning the general performance of the athlete and a corresponding score, both sent to a mobile app. FF aims to help class teaching and personal training, creating a more playful way to progress and maintain young athletes motivation. The technological development process of this product is a perfect context to put to the test some sociological ideas about the relation between technologies and society, particularly in a time of accelerated, permanent and transformative innovation. Even if we are just confronted with one more gamification of a learning device, it is an opportunity to discuss the liberating effects of digital communication techs on society and personal lives.
- A portable lab for the practical study of modern computer engineeringPublication . Dias, Tiago; Sampaio, Pedro; Miguens Matutino, PedroThis demo paper presents the μLIC educational platform. μLIC makes available to the students of Digital Systems and Computer Architecture courses a quite simple, intuitive and portable hardware platform for the realization of their laboratory exercises. μLI C can also be used in other related courses, such as Embedded Systems or Hardware/Software Co-Design, which allows reducing the time needed to study the manuals of diverse development boards and tools and to concentrate the education towards the core contents of the courses. In addition, the low cost, diminished size, and portable nature of the μLIC boards enables students to carry a personal unit with them all the time to implement the class exercises also outside the classrooms, as well as hobby projects. In the demo, three typical lab assignments of Digital Systems, Computer Architecture, and Hardware/Software Co-Design courses are used to showcase the μLIC educational platform: a traffic light controller, a 4-bit Arithmetic and Logic Unit (ALU) and a mini Space Invaders inspired game, respectively.
- Extending the Synoptics of Things (SoT) Framework to Manage ISoS Technology LandscapesPublication . Serras, Bruno; Gonçalves, Carlos; Dias, Tiago; F. G. Osório, A. LuísManaging and monitoring the software and hardware artifacts of an industrial organization are fundamental efforts that can often be challenging endeavors to achieve, especially when such technological landscapes are composed of multiple heterogeneous systems. Usually, Internet of Things (IoT) devices are provided by different suppliers and may use different protocols and interfaces. Thus, the integration of these devices results in complex development and maintenance cycles. The Synoptics of Things (SoT) framework can address these problems, in conjunction with the Informatics System of Systems (ISoS) platform by promoting an open market competitive tech nology landscape for organizations. The purpose of the research presented in this paper was to extend the SoT framework in order to manage and monitor the different elements of an ISoS enabled organization, namely the ISystems (Informatics Systems), CES (Cooperation Enabled Services), and Services. We argue that the SoT framework can be essential in a supervisory control and data acquisition (SCADA) system in today’s modern web, by adopting the concept of Web Components as a standard to enable the development of custom and reusable components. We present and discuss such issues in the context of the HORUS system, an informatic system responsible for payment enforcement in fueling stations. In this system, several devices must work in coordination, such as video cameras and video recorders, which are fundamental for the retrieving of license plate images and, therefore, be continually monitored to ensure the correct functioning of the HORUS system.
- Open-source power outlet system for IoT-based smart homesPublication . Dias, Tiago; Sampaio, Pedro; Cardoso, Diogo; Prates, Cláudio; Jesus, Ricardo; Costa, TiagoThis paper presents an open-source wireless Smart Power Outlet (SPO) system to improve the control and monitoring of household appliances in IoT-based smart homes. The system supports not only the most typical SPO functionalities, such as remote on/off control or real-time monitoring of the current consumption, but also other important functionalities, like programming of the power supply time schedule, automatic interruption of vampire currents, or prevention of electrocutions. Moreover, the devised system architecture allows to connect multiple SPOs, even with different capabilities, in an IEEE 802.15.4 Sub-1 GHz Personal Area Network (PAN). This network is managed by a Controller that also acts as a border router, providing remote access to the SPOs. A prof-of-concept prototype of the system has been implemented and tested. The considered SPO and Controller were based on Simple-Link Sub-1 GHz CC1310 wireless microcontrollers running the Contiki OS. The obtained results demonstrate the basic functionalities offered by the proposed open-source SPO and suggest that it can be used to make the next generation of homes smarter at lower costs.
- Synoptics of Things (SoT): an open framework for the supervision of IoT devicesPublication . Serras, Bruno; Gonçalves, Carlos; Dias, Tiago; F. G. Osório, A. LuísIn the industry, there is a need to manage and monitor systems and their associated devices. This process can be quite complex when the technological landscape is composed of several heterogeneous systems. In such scenarios, both the systems and their devices can be from different suppliers, each one with its own interfaces, often proprietary and non standardized. Moreover, several different administrators can be responsible for the supervision of a system, which greatly complicates the process of supervising multiple systems. Yet, overviewing a technological landscape can be facilitated by the concept of Synoptics, as a fundamental part of a supervisory control and data acquisition system. As modern applications become more and more web based, it makes sense to use web browsers to implement the concept of Synoptics. In this paper, we present the Synoptics of Things (SoT) framework to extend the Synoptics concept to the web domain. The proposed SoT framework explores the concept of Web Components as a standard to enable the development of custom and reusable components for modern web browsers. Such components, or Widgets-IoT, as we call them, can function as an abstraction of both IoT devices and informatics systems, facilitating the interaction with the supervising operators. Accordingly, we present and discuss the use of the SoT framework in an Informatics System of Systems reference implementation to monitor and control the involved systems and the various executive services that compose them.
- Teaching hardware/software co-design using a project-based learning strategyPublication . Miguens Matutino, Pedro; Dias, Tiago; Sampaio, PedroThis paper presents a project-based learning strategy for teaching hardware/software co-design in modern Computer Engineering undergraduate courses. This kind of approach is considered by several recent pedagogical studies as the ideal strategy to support great learning achievements and to increase the proficiency of the students both in the design of digital systems and programming. The proposed strategy, targeting the first-year students, focuses on deepening the knowledge of combinatorial logic, sequential circuits, and state machines, alongside the hierarchical development of software, including for peripheral management.
- Figure follow: A step by step liberating devicePublication . Cavaleiro Rodrigues, José; Dias, Tiago; Silva, CatarinaThe use of ICT has proven to have great results enhancing performance and motivation among sport athletes, and we are exploring the same potential in Compulsory Figures of Artistic Roller Skating. In this poster we present the idea, the technology under development and the impact we expect to obtain when feeding the athletes with information about what their bodies can do, and what they need to learn to become better in Compulsory Figures practice.
