The field of immersive technologies and 3D mapping is rapidly evolving, with a focus on enhancing user experience and improving the accuracy of 3D reconstructions. Researchers are exploring the integration of haptic feedback, virtual reality, and multisensory feedback to create more immersive and interactive environments. Additionally, there is a growing interest in developing efficient and compact 3D mapping systems that can facilitate high-fidelity map sharing and large-scale augmented reality applications. Notable advancements include the development of federated visual positioning systems, real-time 3D Gaussian splatting, and tele-immersive systems with 3D point clouds and vibrotactile feedback. Noteworthy papers include: SubSense, which proposes a novel VR-Haptic framework for immersive control in subsea telerobotics. GS-Share, which introduces a photorealistic map-sharing system with a compact representation. OpenFLAME, which presents a federated visual positioning system for large-scale augmented reality applications. RTGS, which achieves real-time 3D Gaussian splatting SLAM via multi-level redundancy reduction. Capture and Interact, which enables rapid 3D object acquisition and rendering with Gaussian Splatting in Unity. The Stage Comes to You, which presents a low-latency tele-immersive entertainment system with 3D point clouds and vibrotactile feedback.
