ItemAccessible software development: a conceptual model proposal( 2019) Ramiro Gonçalves ; José Luís Martins ; Au Yong Oliveira,M ; Pereira,A ; Sousa e Silva,JSE ; Frederico Branco ; 5754 ; 6516 ; 6499Equal 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.
ItemAssessing the success behind the use of education management information systems in higher education( 2019) José Luís Martins ; Cruz Jesus,F ; Naranjo Zolotov,M ; Oliveira,T ; Au Yong Oliveira,M ; Ramiro Gonçalves ; Frederico Branco ; 6516 ; 5754 ; 6499
ItemCollaborative immersive authoring tool for real-time creation of multisensory VR experiences( 2019) Hugo Rafael Mendes ; Maximino Bessa ; José Luís Martins ; Miguel Correia Melo ; 6516 ; 5408 ; 5095 ; 7622With the appearance of innovative virtual reality (VR) technologies, the need to create immersive content arose. Although there are already some non-immersive solutions to address immersive audio-visual content, there are no solutions that allow the creation of immersive multisensory content. This work proposes a novel architecture for a collaborative immersive tool that allows the creation of multisensory VR experiences in real-time, thus promoting the expeditious development, adoption, and use of immersive systems and enabling the building of custom-solutions that can be used in an intuitive manner to support organizations’ business initiatives. To validate the presented proposal, two approaches for the authoring tools (Desktop interface and Immersive interface) were subjected to a set of tests and evaluations consisting of a usability study that demonstrated not only the participants’ acceptance of the authoring tool but also the importance of using immersive interfaces for the creation of such VR experiences. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
ItemEvaluation of e-commerce websites accessibility and usability: an e-commerce platform analysis with the inclusion of blind users( 2018) Ramiro Gonçalves ; Rocha,T ; José Luís Martins ; Frederico Branco ; Au Yong Oliveira,M ; 6516 ; 6499 ; 5754Considering the importance associated with e-commerce website accessibility and usability, a study on one of the most relevant Portuguese e-commerce websites has been performed using both automatic and manual assessment procedures. In an initial stage, we evaluated the chosen website with a Web accessibility and usability automatic tool called SortSite; after that, we performed a manual evaluation to verify each previously detected error and present possible solutions to overcome those faults. In a third phase, three usability specialists have been used to perform a heuristic evaluation of the chosen website. Finally, user tests with blind people were carried out in order to fully assess the compliance with accessibility and usability guidelines and standards. The results showed that the platform had a good score regarding the automatic evaluation; however, when the heuristic and manual evaluations were performed, some accessibility and usability problems were discovered. Moreover, the user test results showed bad marks regarding efficiency, effectiveness, and satisfaction by the group of participants. As a conclusion, we highlight user interaction problems and propose seven recommendations focused on enhancing accessibility and usability of not only the evaluated e-commerce website, but also of other similar ones. © 2017 Springer-Verlag GmbH Germany
