Multifocal Stereoscopic Projection Mapping

Abstract

Fig. 1. The proposed multifocal stereoscopic projection mapping technique mitigates the vergence-accommodation conflict by placing the virtual image (as an optical term) at the desired distance from an observer using focal-sweep active shutter glasses and a synchronized high-speed projector. (a) Prototype system; (b) experimental setup to show the multifocal appearance of Stanford bunnies onto a flat surface (D) whose virtual images were placed, from near to far, at points at which three physical objects (A-C) were placed; (c-e) captured scene observed through a focal sweep lens. The bunnies, as well as the physical objects, appeared focused from the bottom to the top according to the focus distance of the camera lens at (c) near, (d) middle, and (e) far.
