Accommodation response for visually equivalent light field 3D display

Visually Equivalent Light Field 3D (VELF3D) is an autostereoscopic flat-panel 3D display. Though it has a very simple structure, it can reproduce not only binocular parallax and convergence but also smooth motion parallax. It displays multiple viewing zones and uses oblong pixels and a parallax barrier to enable adjacent zones to be linearly blended well and provide continuous reproduction of motion parallax. However, the potential for accommodation reproducibility has yet to be clarified. In this paper, we demonstrate accommodation responses of monocular vision induced by changes in displayed depth as determined by an autorefractor / keratometer. We calculate point spread functions and retinal images when an observer is watching a linear blending display, and analyze mechanisms to induce accommodation.
