In this research paper titled “Past Brush: A System for Actively Reliving the Past by Partially Overlaying Historical Videos onto the Real World,” the authors propose a system that allows users to experience the past as if it were happening in the present. By selectively displaying historical videos in specific directions without drawing boundaries in the physical space, the system creates an illusion that the events are unfolding in real-time. This system aims to create a sense of connection between the past and the present, enabling users to remember the historical videos as personal experiences rather than just images. It seems like this research aligns with the concept of a “Camera that Can Manipulate Time.”
