8K Time into Space is a user interface for a video exploration system with an 8K display. 8K is an ultra high-definition video system and it can present a huge amount of visual content on one display. In our system, video thumbnails with shifted playback time in chronological order are spaced out like tiles. The time range of a scene that a viewer wants to check can be adjusted with a touch interface, and resolution of the thumbnails is changed depending of the range. 8K Time into Space aims to provide responsive and intuitive experiences for video consumption.
