Desenvolvimento de mini-mapa interativo e interfaces naturais de usuário para navegação em aplicações de realidade virtual com terrenos de grande escala

Abstract

The use of virtual reality can provide users with experiences that would not be possible in conventional three-dimensional applications. The ability to interact, move, and observe while immersed in the application introduces new paradigms in human-computer interaction. This work aims to incorporate virtual reality features into large-scale virtual environments. This includes the addition of technologies such as motion tracking and interactive interfaces, providing an immersive experience where users can explore and interact with 3D digital environments. To enable user navigation across extensive terrains, a mini-map has been implemented to assist in visualizing the entire 3D scene, as well as allowing teleportation to any selected location. To enhance user interaction with the system, various forms of radial menus have been proposed and tested, aiming to enable natural interactions and introduce new ways of interacting with the application. The components produced during the research were incorporated into the SIS-ASTROS simulator, allowing the visualization of activities present in the simulation from a first-person perspective. The technique of using a mini-map for teleportation proved advantageous in navigating extensive terrains, saving time compared to conventional movements to scattered points of interest on the map. Furthermore, the radial menu, which allows the selection of different functionalities by rotating the wrist, enriched the virtual reality experience, providing new ways of humancomputer interaction.
