Demonstrating real-time slow-motion experience through parallel video presentation

Real-time and slow-motion are basically incompatible properties in the technologies of recording and playback. We propose a framework to realize the coexistence of both using parallel video presentation based on the integrative capacity and the temporal nature of cognition. In this framework, camera input is divided into short time durations, distributed into layered timelines, and then stretched out. And then, all layers are composited and presented in a display simultaneously. In our demonstration, users can experience their surroundings through see-through goggles or digital mirrors in which this framework is embedded. Under certain conditions, the perception of the layers is integrated into the cognitive process, resulting in the coexistence of real-time and slow-motion. This research suggests a new field of “Temporal Editing to Humans.”
