Description
Summary:Made available in DSpace on 2015-04-14T14:50:14Z (GMT). No. of bitstreams: 1 459531.pdf: 3667250 bytes, checksum: bb55b361fd8ade0691af28d700b6b8f9 (MD5) Previous issue date: 2012-11-28 === One of the difficulties faced by unmanned vehicles operators is to understand the situation of the vehicle in the local where it is and the relationship of the events that occur there with the vehicle and with the mission that is being executed. This may happen due to the type of control station used and the resources available both in the station as in the vehicle. In this context, this paper investigates how the technologies of Virtual Reality, Augmented Reality and Immersive Telepresence, when used simultaneously, are able to increase the situational awareness of unmanned vehicle operator and the navigation efficiency. For this reason, this paper proposes a control and navigation system to unmanned ground vehicle whose main feature is the simultaneous use of resources related to Virtual Reality, Augmented Reality and Immersive Telepresence. Besides the system, as a way to facilitate the evaluation of this system, were implemented also an unmanned ground vehicle simulator and a tool for visualization and analysis the data generated during the use of the simulator. Regarding of the navigation efficiency, this system was evaluated from the data that describe the vehicle behavior. Concerning the situational awareness, this system was evaluated using the SAGAT method. The results obtained indicate that an immersive instrument is useful when the tasks executed by the vehicle depend on the detailed observation of the local where the vehicle is. However, tasks associated with the pure and simple navigation can be executed with good performance even without the immersive instrument. === Uma das dificuldades enfrentadas pelos operadores de ve?culos n?o tripulados ? entender a situa??o do ve?culo no local onde ele se encontra e a rela??o dos eventos que l? ocorrem com o ve?culo e com a miss?o sendo realizada. Isto pode acontecer devido ao tipo de esta??o de controle utilizada e aos recursos dispon?veis tanto na esta??o quanto no ve?culo. Neste contexto, este trabalho investiga o quanto as tecnologias de Realidade Virtual, Realidade Aumentada e Telepresen?a Imersiva, quando empregadas de forma simult?nea, s?o capazes de aumentar a consci?ncia situacional do operador de um ve?culo n?o tripulado e a efici?ncia da navega??o. Para isso, este trabalho prop?e um sistema de controle e navega??o aplic?vel a ve?culos terrestres n?o tripulados cuja principal caracter?stica ? o emprego simult?neo de recursos ligados a Realidade Virtual, Realidade Aumentada e Telepresen?a Imersiva. Como forma de viabilizar a avalia??o deste sistema, foram implementados tamb?m um simulador de ve?culo terrestre n?o tripulado e uma ferramenta de visualiza??o e an?lise dos dados gerados durante o uso do simulador. No que diz respeito ? efici?ncia de navega??o, este sistema foi avaliado a partir dos dados que descrevem o comportamento do ve?culo. Quanto ? consci?ncia situacional, este sistema foi avaliado atrav?s do m?todo SAGAT. Os resultados obtidos indicam que um aparato imersivo ? ?til quando as tarefas realizadas atrav?s do ve?culo dependem da observa??o detalhada do local onde o ve?culo se encontra. Entretanto, tarefas associadas ? navega??o pura e simples podem ser realizadas com bom desempenho mesmo sem o aparato imersivo.
