This paper proposes a novel concept of light whose propagating speed is very slow so that human can perceive the propagation of light. We call it hyper slow light (HSL) and construct virtual reality (VR) systems in which participants can understand the concept through interaction with HSL. To represent HSL, we extend the model of spatio-temporal video to propagating spatio-temporal video in which each video frame is moving in the temporal dimension. We propose two HSL browsing models whose light sources are a projector and a physical scene, respectively. Based on the models, we propose three prototype browsing systems. Through a user test, we confirmed that all the participants could understand the concept of HSL well by experiencing the prototype systems. The participants found that a system which emitted recorded video as HSL from a projector was the most suitable for representing HSL, and perceived the existence of HSL the most strongly from it.
