Touch-Consistent Perspective for Direct Interaction under Motion Parallax

A 3D display is a key component to present virtual space in an intuitive way to users. A motion parallax-based 3D display can be easily combined with multi-touch surfaces, and it is expected to bring a natural experience of viewing and controlling 3D space. However, since virtual objects are rendered in accordance with the head position of the user, their projected positions are not fixed on the display surface. We propose a novel formulation of head-coupled perspective that adaptively changes the position of the projection image plane to maintain touch consistency of direct interaction.
