Scoopirit
Yu Matsuura, Naoya Koizumi · 2018
We propose Scoopirit, a system that displays an image standing vertically at an arbitrary three-dimensional position under and on a water surface. Users can scoop the image from an arbitrary horizontal position on water surface with their bare hands. So that it can be installed in public spaces containing water surfaces visited by an unspecified number of people, Scoopirit displays images without adding anything to the water and enables user to interact with the image without wearing a device. Because of the configuration of the system, users can easily understand the relationship between the real space and the image. This study makes three contributions. First, we propose a method to scoop the mid-air image at an arbitrary horizontal position. Second, we design the offset that is useful for measuring the water level of the water surface scooped with an RGB-D camera. Third, we propose a method to design interaction areas.
