- Cross-device platform for collaborative and immersive experiences in mixed realityPublication . Lucas, Letícia; Costa, Carla; Jorge, Pedro MendesThis work aims to develop a platform for managing Augmented Reality (AR) and Virtual Reality (VR) devices, enabling multiple users to engage in collaborative and immersive experiences occurring both in the physical and digital world. The proposed solution addresses challenges in synchronization, data transmission, and real-time rendering, so that the multiple participants - either co-located or geographically dispersed - can share a unified, high-fidelity experience. This research intends to advance mixed reality technologies for education, entertainment, and business purposes. To demonstrate this cross-device approach, an application using the MagicLeap2 and MetaQuest3 devices is implemented. This application allows various users to collaboratively interact within the same mixed reality environment. Unity3D is the core framework of this system, and OpenXR is the layer that ensures hardware compatibility.

- Real-time GPS indoor for USV tracking using lookup tablePublication . Vieira, Fábio; Teodoro, Pedro; Jorge, Pedro MendesThis study introduces an approach that utilizes Lookup Tables (LUT) to enable real-time tracking of an Unmanned Surface Vehicle (USV) in an indoor setting, using a fish-eye camera. The proposed method streamlines image processing and achieves O(1) complexity, significantly reducing application run time. The paper also outlines the process of calibrating the fish-eye camera to correct image distortion, computing the homography matrix for re-projection, and obtaining a virtual top view of the camera’s field of view. The paper provides a detailed explanation of the replacement of the undistortion and re-projection steps with the new LUT method. Experimental results demonstrate a significant enhancement in the process’s run time, making it feasible for real-time tracking, regardless of the image size.
