Remote collaboration has always posed challenges, especially when it comes to working on physical objects. However, a new system called SharedNeRF is changing the game by allowing users to manipulate a 3D view of the scene in real time. This innovative approach opens up new possibilities for complex tasks like debugging hardware and assembling objects, making remote collaboration more effective and efficient.
SharedNeRF is a remote conferencing tool developed by Mose Sakashita, a doctoral student in the field of information science. This system combines two graphics rendering techniques to provide a unique experience for remote users. By leveraging photorealistic rendering and view-dependent rendering, SharedNeRF allows users to immerse themselves in the physical space of their collaborators in real time. This approach represents a paradigm shift in remote collaboration, enabling users to work on tasks that were previously challenging to convey through traditional video-based systems.
The core of SharedNeRF lies in its use of a neural radiance field (NeRF) for rendering scenes in 3D. NeRF employs artificial intelligence to construct detailed and realistic depictions of scenes, complete with reflections, transparent objects, and accurate textures. The local collaborator records the scene using a head-mounted camera, which feeds into the NeRF model to render the scene for the remote user. Additionally, point cloud rendering is used to provide real-time updates of dynamic elements in the scene, such as moving hands. By merging these two rendering techniques, SharedNeRF offers users a comprehensive view of the scene from various angles in high quality.
Seven volunteers participated in a test of SharedNeRF by collaborating on a flower-arranging project. The results showed that the system outperformed standard video conferencing tools and point cloud rendering alone. The volunteers appreciated the ability to independently change viewpoints, zoom in and out on the arrangement, and observe real-time movements in the scene. This feedback indicates that SharedNeRF enhances users’ control over what they see and helps them focus on the details of the task at hand.
While currently designed for one-on-one collaboration, SharedNeRF has the potential to be expanded to accommodate multiple users. Future work will focus on improving image quality and exploring immersive experiences through virtual reality or augmented reality techniques. The researchers behind SharedNeRF are committed to enhancing the system’s capabilities to provide a seamless and engaging remote collaboration experience for users.
SharedNeRF represents a groundbreaking approach to remote collaboration, leveraging advanced graphics rendering techniques to bridge the gap between physical space and virtual interaction. By enabling users to manipulate a 3D view of the scene in real time, SharedNeRF opens up new possibilities for collaborative tasks that were previously challenging to accomplish remotely. As technology continues to evolve, systems like SharedNeRF pave the way for more effective and immersive remote collaboration experiences.
