Abstract(s)
A Realidade Aumentada veio alterar a percepção que o ser humano tem do mundo real. A expansão da nossa realidade à Realidade Virtual possibilita a criação de novas experiencias, cuja aplicabilidade é já tida como natural em diversas situações. No entanto, potenciar este tipo de interacção pode ser um processo complexo, quer por limitações tecnológicas, quer pela gestão dos recursos envolvidos. O desenvolvimento de projectos com realidade aumentada para fins comerciais passa assim muitas vezes pela optimização dos recursos utilizados tendo em consideração as limitações das tecnologias envolventes (sistemas de detecção de movimento e voz, detecção de padrões, GPS, análise de imagens, sensores biométricos, etc.).
Com a vulgarização e aceitação das técnicas de Realidade Aumentada em muitas áreas (medicina, educação, lazer, etc.), torna-se também necessário que estas técnicas sejam transversais aos dispositivos que utilizamos diariamente (computadores, tablets, telemóveis etc.). Um dominador comum entre estes dispositivos é a internet uma vez que as aplicações online conseguem abarcar um maior número de pessoas.
O objectivo deste projecto era o de criar uma aplicação web com técnicas de Realidade Aumentada e cujos conteúdos fossem geridos pelos utilizadores. O processo de investigação e desenvolvimento deste trabalho passou assim por uma fase fundamental de prototipagem para seleccionar as tecnologias que melhor se enquadravam no tipo de arquitectura pretendida para a aplicação e nas ferramentas de desenvolvimento utilizadas pela empresa onde o projecto foi desenvolvido.
A aplicação final é composta por um FrontOffice, responsável por mostrar e interpretar as aplicações criadas e possibilitar a integração com outras aplicações, e um BackOffice que possibilita aos utilizadores, sem conhecimentos de programação, criar novas aplicações de realidade aumentada e gerir os conteúdos multimédia utilizados.
A aplicação desenvolvida pode servir de base para outras aplicações e ser reutilizável noutros âmbitos, sempre com o objectivo de reduzir custos de desenvolvimento e de gestão de conteúdos, proporcionando assim a implementação de uma Framework que permite a gestão de conteúdos em diferentes áreas (medicina, educação, lazer, etc.), onde os utilizadores podem criar as suas próprias aplicações, jogos e ferramentas de trabalho. No decorrer do projecto, a aplicação foi validada por especialistas garantindo o cumprimento dos objectivos propostos.
Augmented Reality has changed the way we view and interact with the real world. By expanding our reality with virtual realities allows the creation of new experiences. The applicability of these experiences, often result in a natural way to interact with virtual content, despite the fact that, creating such interaction can be complex, either by management or by the technological limitations of the involved resources. The development of augmented reality projects, for commercial purposes, is often driven to optimize resources by taking into account the limitations of the technologies surrounding the systems (voice and motion detection, pattern detection, GPS, image analysis, biometric sensors, etc.). There are many areas where augmented reality is applied (medicine, education, leisure etc.), with the popularization and reception of these techniques, it is necessary that this applications can be applied in every day devices (computers, tablet computers, mobile phones etc.). A common dominator between these devices is the Internet, therefore, applications that run online can reach a greater number of people. In this perspective, the objective of this thesis project is to create a web application that uses augmented reality techniques whose contents are manageable by users. The application will consist on a FrontOffice and a BackOffice, which can be used by users, without programming knowledge, to create new applications with augmented reality and manage the media used. The FrontOffice will be responsible for display and interpret the created applications and enable integration with other applications in the browser. The process of research and development will go through a prototyping phase to find technologies that fit the type of architecture required for the application and development tools used by the company where the project will be developed. It is the intention to build an application that serves as the basis for other applications and can be reusable in other areas, always with the aim of reducing development costs and subsequent management of content. During the project, the application was verified by experts, thus providing the implementation of a framework that enables content management in different areas (medicine, education, leisure, etc…), where users can create their own applications, games and work tools.
