# RealityReplay: Detecting and Replaying Temporal Changes In Situ using Mixed Reality ## Overview **Authors:** Hyunsung Cho, Matthew Komar, David Lindlbauer **Publication Date:** 1 January 2023 **Link:** **Keywords:** AR / VR / XR, Context-Aware Computing, time-traveling, egocentric, semantic segmentation, Mixed-Reality (MR), RealityReplay, In-situations Visualization, short-term memory, 360-degree Camera, head-mounted display (HMD), augmented awareness **Type:** Peer-Reviewed Journals/White Papers ## Summary Humans easily miss events in their surroundings due to limited short-term memory and field of view. This happens, for example, while watching an instructor's machine repair demonstration or conversing during a sports game. We present RealityReplay, a novel Mixed Reality (MR) approach that tracks and visualizes these significant events using in-situ MR visualizations without modifying the physical space. It requires only a head-mounted MR display and a 360-degree camera. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
