Resumo: Nowadays, additional information can be required to aid with certain tasks as well as to enhance educational and entertainment experiences. A possible solution to support these activities is the use of Augmented Reality (AR), allowing an easier access and a better perception of additional layers of content superimposed onto reality. In this context, Pervasive AR experiences can be used to enrich the real world with virtual content that is visualized continuously as the user moves through the space. However, the creation of such experiences depends on authoring tools that overcome the existing difficulties and facilitate this task. These must be accessible for inexperienced users while also providing experts the full potential of the technology. In this dissertation, two applications were developed: desktop and mobile, both capable of being used for the creation, configuration and visualization of pervasive AR experiences. The system developed makes use of a scan of a physical environment to provide a digital reconstructed representation of that space to the desktop platform and to enable the positional tracking in the mobile platform. While the desktop application presents the user with a non-immersive Virtual Reality (VR) setting and the mobile application provides continuous AR in the physical environment, both scenarios can be used to place virtual content on and ultimately configure an AR experience. The authoring capabilities of both platforms were compared by conducting a user study focused on evaluating their usability. As a result, the positive feedback of the participants shows that these platforms appear to be a valid solution to pursue the goal of having pervasive experiences in large environments, which users can explore, interact with and learn from.

Uma possível solução no suporte destas actividades é o uso de Realidade Aumentada (RA), possibilitando um acesso facilitado e uma melhor percepção de camadas adicionais de conteúdo sobreposto na realidade. Neste contexto, experiências de RA pervasivas podem ser usadas para enriquecer o mundo real com conteúdo virtual que é visualizado continuamente conforme o utilizador se move pelo espaço. No entanto, a criação de tais experiências depende de ferramentas de configuração que superem as dificuldades existentes e facilitem esta tarefa. Estas devem ser acessíveis para utilizadores inexperientes e, ao mesmo tempo, disponibilizar aos experientes todo o potencial da tecnologia. No âmbito desta dissertação, foram desenvolvidas duas aplicações: desktop e mobile, ambas capazes de serem usadas para a criação, configuração e visualização de experiências de RA pervasivas. O sistema desenvolvido faz uso de uma digitalização de um ambiente físico para fornecer uma representação digital reconstruída desse espaço à plataforma desktop e para permitir a localização na plataforma mobile. Enquanto a aplicação desktop apresenta ao utilizador um cenário de Realidade Virtual (RV) não imersivo e a aplicação mobile providencia RA contínua no ambiente físico, ambos os cenários podem ser usados para se colocar conteúdo virtual e por fim configurar uma experiência de RA. As capacidades de configuração de ambas as plataformas foram comparadas conduzindo um estudo focado em avaliar a sua usabilidade. Como resultado, os pareceres positivos dos participantes mostram que estas plataformas evidenciam ser uma solução válida para atingir o objectivo de conseguir experiências pervasivas em grandes ambientes, nos quais os utilizadores podem explorar, interagir e aprender.2022-05-19T11:16:35Z2021-12-03T00:00:00Z2021-12-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/33926engNeves, Pedro Miguel Oliveirainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T12:05:16Zoai:ria.ua.pt:10773/33926Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:05:16.691601Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
