Memento Player: Shared Multi-Perspective Playback of Volumetrically-Captured Moments in Augmented Reality

Capturing and reliving memories allow us to record, understand and share our past experiences. Currently, the most common approach to revisiting past moments is viewing photos and videos. These 2D media capture past events that reflect a recorder’s first-person perspective. The development of technology for accurately capturing 3D content presents an opportunity for new types of memory reliving, allowing greater immersion without perspective limitations. In this work, we adopt 2D and 3D moment-recording techniques and build a moment-reliving experience in AR that combines both display methods. Specifically, we use AR glasses to record 2D point-of-view (POV) videos, and volumetric capture to reconstruct 3D moments in AR. We allow seamless switching between AR and POV videos to enable immersive moment reliving and viewing of high-resolution details. Users can also navigate to a specific point in time using playback controls. Control is synchronized between multiple users for shared viewing.
