Abstract(s)
As unidades de mergulhadores da Marinha conduzem ações, em níveis admissíveis de ameaça, para a recolha de dados críticos em cenários de operações de natureza anfíbia. Para execução dessas missões, os mergulhadores têm necessidade de efetuar o reconhecimento de costa recolhendo dados dos locais de desembarque das forças anfíbias ou efetuando a limpeza desses locais e dos canais de acesso, de minas e outros obstáculos.
Atualmente, as operações de reconhecimento já envolvem coleta de dados efetuada de forma manual e automática, bem como o registo e a transmissão dos dados. Contudo, esse processo tem-se revelado ineficiente e propenso à ocorrência de erros, principalmente na fase de recolha dos dados.
A presente dissertação visou a conceção, desenho e implementação de uma solução suscetível de ir ao encontro das necessidades operacionais dos mergulhadores da Marinha. Para o efeito, foi realizado um estudo prévio dos requisitos funcionais e não funcionais das operações anfíbias. O estudo em causa deu ênfase especial ao design da aplicação, particularmente ao design de interação e ao design centrado no utilizador, tendo por referência os mais recentes desenvolvimentos no domínio da experiência de utilização.
A solução a desenvolver passou por diferentes fases de desenho, que incluíram a construção de protótipos de baixa, média e alta fidelidade, para os quais foram efetuados testes de usabilidade. Findo esse processo, procedeu-se ao desenvolvimento da aplicação de forma a ser disponibilizada em dispositivos móveis. Testes finais da aplicação móvel desenvolvida revelaram ganhos assinaláveis nas métricas de usabilidade, nomeadamente na eficiência e satisfação de uso, quando comparada a operação da anterior solução.
The Navy's diver units conduct actions at admissible threat levels that enable the efficient and effective collection of data relating to the area of operations by performing amphibious operations. In order to carry out their missions, the scuba divers units need to recognize the coast, in order to collect information about the landing places of the amphibious forces, the cleaning of landing places and their respective access channels, mines and others obstacles. Nowadays, these kind of reconnaissance operations already involve data collections, made manual and automatically, as well as the registration and transmission of these data. However, these process has been revealed as inefficient and mistakes are easily made, specially in the data collection phase. The present research aims to create, design and implement a solution for the operational needs of the scuba divers units. With this in mind, a preliminary study was carried about the functional and non-functional requirements of the amphibious operations. That study gave special importance to the design of the app, particularly the design of interaction and the user-centered design, having, as a basis, the most recent developments in the utilization experiments. in order to overcome the lack of a simple, automatic and intuitive form of registration, a solution was developed which consisted in the creation of an application, which has the function of assisting divers on the ground. The solution had several phases, including the construction of protypes of low, medium and high fidelity, to which, tests of utilization were made. When the process was over, an app for mobile devices was developed. Final tests of this mobile app, revealed remarkable gains and results in the utilization metrics, specially when compared to the previous solution.
