Abstract(s)
O e-commerce tem feito cada vez mais parte da preferência dos portugueses no que
toca à realização das suas compras, tendo-se refletido também num aumento das
desigualdades no acesso à web. As pessoas com deficiência, nomeadamente visual,
enfrentam ainda muitas dificuldades no acesso ao comércio eletrónico. Ainda que haja
implementação das diretrizes de acessibilidade existentes e legisladas, o problema reside
tendencialmente em falhas de usabilidade. Este facto verifica-se pela falta de inclusão de
utilizadores com deficiência visual, não só durante a fase de testes (de usabilidade), como
também durante o processo de desenvolvimento destes projetos.
Esta dissertação visa apresentar um conjunto de diretrizes de usabilidade a ter em
conta na criação de plataformas de comércio online inclusivas.
Neste sentido, a investigação que irá decorrer ao longo deste trabalho permitirá
apurar barreiras no acesso ao comércio online e, através da análise e discussão dos
problemas, elaborar um conjunto de diretrizes que visam aumentar a usabilidade a
pessoas com deficiência visual em plataformas e-commerce, quer sejam mobile ou web.
Para suportar os resultados obtidos, será desenvolvida prototipagem no sentido de
orientar visualmente as diretrizes reunidas, cujo processo passará pela prototipagem de
baixa, média e alta fidelidade. Adicionalmente, será elaborado um livro digital que
compile as principais conclusões, as diretrizes e a sua componente visual. Este elemento
permitirá a comunicação clara dos princípios que pretendem ser divulgados, quer a
designers, quer a empresas que pretendam aumentar o seu foco no conceito da
usabilidade e da acessibilidade. Será também possível consciencializar os leitores sobre
deficiência visual e criar mais oportunidade de discussão sobre inclusividade.
E-commerce has highly become a preference of Portuguese society when it comes to making their purchases, which it also reflects on an increase of difficulties using the web. People with disabilities, mostly visually impaired, still face many barriers accessing e-commerce. Although the implementation of legislated accessibility guidelines, the problem tends to reside in usability flaws. This fact is verified by the lack of inclusion of visually impaired users, not only during (usability) tests, but also during the development process of these projects. This dissertation foremost seeks to present a set of usability guidelines to consider when creating inclusive e-commerce platforms. Therefore, the investigation that will occur throughout this work will allow us to identify barriers and, through the analysis and discussion of the problems, to develop a set of guidelines that seeks the increase of usability to visually impaired users in ecommerce platforms, whether mobile or web. To support the results, a prototype will be developed to visually attend the guidelines, whose process will pass through low, medium, and high-fidelity prototyping. Additionally, an e-book will be prepared and it compiles the main conclusions, the guidelines, and its visual component. This element will allow us to share these principles with designers and companies that want to increase their focus on usability and accessibility. It will also be possible to be more aware of visual impairment and create more opportunities to discuss inclusivity.
