Proposal of an interactive color painting method for mid-air CG objects reflecting finger movements and colors

In this study, we developed a method with the aim of making virtual objects appear more realistically in the real space. This method allows users to paint colors interactively onto a 3DCG object displayed in three dimensions in mid-air by touching it with their fingers. The color applied to the CG object reflects the color of the touching finger. Because the movements and color of the finger in the real space are directly reflected onto the CG object in the virtual space, it is expected that the boundary between the virtual and real spaces will become blurred, thereby enhancing the sensation that the CG object exists in the real world.
