- Accessibility in Software Engineering: Pursuing the Mainstream from a ClassroomPublication . Silva, João; Gonçalves, Ramiro; Martins, José; Branco, Frederico; Pereira, AntónioThough equal access to all digital devices, content and applications should be ensured by default in the Digital Age, reality has yet to match this ideal, despite the numerous efforts to raise awareness of the problem. For the visually impaired, the existence of e-accessibility issues represents a barrier that, in the majority of situations, cannot be overcome. Nevertheless, this group of individuals still insists on using digital devices, to carry out tasks from their daily lives, such as reading and writing e-mails, reading news and weather websites, and using social networks. This assumption has been validated through a survey completed by 29 blind or partially sighted individuals. Considering that the lack of depth of knowledge in developers constitutes one of the most significant constraints to the development of accessibility software and digital content, the proposal for “slide 0” to be included as an educational resource, when developers are learning how to engineer software, is discussed later in the paper. This contribution, if precisely focused on the various types of software projects, would represent a novel addition to the existing scientific literature, but also a comprehensive aid to the inclusion of e-accessibility when lecturing experts on software engineering.
- Accessibility Not on Demand - An Impaired SituationPublication . Silva, João de Sousa e; Gonçalves, Ramiro; Pereira, AntónioDigital accessibility is recognized as a fundamental tool for an egalitarian society. Nevertheless, software accessibility is an under addressed topic in the discipline of software engineering and the academy in general. As a result, its development and implementation is compromised. This problem is depicted here with the help of some experiments that shows the poor attention which is dedicated to this topic. Some hypotheses that try to explain this problem are formulated, and some possible solutions are debated. As a conclusion, some insights are given and a new possible researched avenue is presented.
- Accessible software development: a conceptual model proposalPublication . Silva, João Sousa e; Gonçalves, Ramiro; Branco, Frederico; Au‑Yong‑Oliveira, Manuel; Martins, José; Pereira, AntónioEqual access to all software and digital content should be a reality in the Digital Era. This argument is something defended both by existing regulations, norms and standards, and also business organizations and governments. Despite this acknowledgement, the reality is still far from the desired equality. For certain groups of disabled or impaired citizens, such as the visually impaired, the existence of e-accessibility compliance represents an opportunity to integrate, in a more simple and straightforward manner, their societies. Despite the existing poor results on e-accessibility compliance, the mentioned citizens insist on using digital devices in their daily lives. Even though, in the last decade, multiple standards and regulations have been published towards indicating how to develop accessible digital user interfaces, there are still two major issues surrounding its implementation: the complexity and disparity of the documents containing the abovementioned norms, and also the lack of e-accessibility know-how by software experts. With this in mind, a proposal for an accessible software development model that encompasses e-accessibility incorporation as one of the development process activities has been presented. This model might represent a very interesting support tool for software development organizations and a novel resource for learning and training institutions to be able to improve their computer science and informatics students’ skills on e-accessibility.
- Agile Accessibility Assessment: Development and Evaluation of Native SoftwarePublication . de Sousa e Silva, João; Pereira, António; Ferreira, Rui Bragança; Gonçalves, RamiroThe information and communication technologies (ICT) have the potential to improve the quality of life of individual with functional particularities, potentiating their activity in society, as well supplying the conditions for a prolonged active life, counter acting the natural age related lost of faculties. As such, the software component – of ICT – is lacking a good and attentive construction to these functioning details which, often, are of difficult assessment. Adding to these constrains, the existing information is, not exclusively but especially, focused on Web contents. Attending to these matters, a checklist of proposals has been elaborated, and presented in this paper, that tries to cover these flaws, allowing for an evaluation of the accessibility of Integrated Development Environments (IDE), their capacity of generating accessible software – native software and not Web contents -, and even the accessibility of the final product – the native software. Conceived through the reutilization and inspired on the general knowledge created by the Web Accessibility Initiative (WAI), the drafts of this checklist are easily understandable and applicable. With the objective of facilitating the work of information systems technician who may already have concerns regarding these topics, it further has the important potential of encouraging agents to initiate themselves into the cares that this are requires.

A theorybuilding research shows a framework with 12 key design factors to consider, which managers might use to develop projects and researchers may adopt for further investigation in the area of Contact Center design. This work intends to provide a valuable link between the research community and practitioners in industry.
- GUI generation based on language extensions: a model to generate GUI, based on source code with custom attributesPublication . Monteiro, Marco; Oliveira, Paula; Gonçalves, RamiroDue to data-driven application nature and its increasing complexity, developing its user interface can be a repetitive and time-consuming activity. Consequently, developers tend to focus more on the user interface aspects and less on business related code. In this paper, we’re presenting an alternative approach to graphical user interface development for data-driven applications, that allows developers to refocus on the source code and concentrate their efforts on application core logic. The key concept behind our approach is the generation of concrete graphical user interface from a source code based model, which includes the original source code metadata and non-intrusive declarative language extensions that describes the user interface structure. Concrete user interface implementation will be delegated to specialized software packages, developed by external entities, that provides complete graphical user interfaces services to the application. When applying our approach, we’re expecting faster graphical user interface development.
- IntelligentCart: Architecture of an Innovative System for the Acquisition of Products in Grocery StoresPublication . Santos, Diana S.S.; Pereira, António; Gonçalves, RamiroLarge grocery stores are nowadays used by millions of people for the acquisition of an enlarging number of products. Product acquisition represents a complex process that comprises time spent in corridors, product location and checkout queues. On the other hand, it is becoming increasingly difficult for retailers to keep their clients loyal and to predict their needs due to the influence of competition and the lack of tools that discriminate consumption patterns. In this article it is presented the proposal of an architecture and solution of an innovative system for the acquisition of products in grocery stores (IntelligentCart). The IntelligentCart explores emerging mobile technologies and automatic identification technologies (such as RFID) as a way to improve the quality of services provided by retailers and to augment the consumer value thus allowing to save time and money.
- Intrusion detection systems in Internet of Things: A literature reviewPublication . Simões Santos, Leonel Filipe; Rabadão, Carlos; Gonçalves, RamiroThe Internet of Things (IoT) is a new model that integrates physical objects and Internet and became one of the principal technological evolutions of computing. It is estimated that a trillion of physical objects will be connected to the Internet until 2022. The low accessibility and the lack of interoperability of many of these devices in a vast heterogenous landscape will make it very hard to design specific security measures and apply specific security mechanism. Moreover, IoT networks still exposed and vulnerable to attacks aimed to disrupt the network. Therefore, additional security tools specific to IoT are needed. Intrusion Detection System (IDS) could fulfill this purpose. In this paper, we present a literature review on the IDS in IoT topic, mainly focusing on the current state of research by examining the literature, identifying current trends and presenting open issues and future directions.
- Making Software Accessible, but not Assistive: A Proposal for a First Insight for StudentsPublication . Silva, João de Sousa e; Gonçalves, Ramiro; Martins, José; Pereira, AntónioThe academy can and should have a major role in the promotion of software accessibility. To try to clarify a number of empirical arguments and certainties regarding the usage of accessible, but not assistive, software, the answers to a survey given to 15 blind or low vision people are depicted. To demonstrate how under addressed this topic is by the academy an experiment was made, and its results are portrayed. The novel contribution that this paper offers is the relation between relevant accessibility documentation to its appropriate type of user interface, which is intended to encourage the introduction of the topic of software accessibility implementation. Also, a proposal for a first slide, regarding accessibility implementation in software meant to be shown to software engineering students, who should produce accessible software in their future, is presented. As a conclusion, some insights are given and new possible research avenues are depicted.
- Management framework for used cooking oil collectionPublication . Sousa, André; Faria, José; Gonçalves, Ramiro; Pereira, António; Barroso, JoãoThe production of waste pollutants has increased in recent decades at an impressive rate. These pollutants pose a threat to life on our planet, so it is increasingly important to process them correctly. Fortunately, today it is possible to obtain profit through the reuse and recycling of most of these residues, in particular, of vegetable oil, which is especially interesting due to the potential of transforming it into biodiesel. However, this process does present some constraints, mainly related to the operating costs associated with its collection. This paper proposes a new platform that aims to simplify the bureaucracy of the process and optimize the collection routes, thus maximizing the potential profit to be obtained from this business.
