We present a focal surface projection to solve the narrow depth‐of‐field problem in projection mapping applications. We apply a phase‐only spatial light modulator to realize nonuniform focusing distances, whereby the projected contents appear focused on a surface with considerable depth variations. The feasibility of the proposed technique was validated through a physical experiment.
The ideal AR x-ray vision should enable users to clearly observe and grasp not only occludees, but also occluders. We propose a novel selective visualization method of both occludee and oc-cluder layers with dynamic opacity depending on the user's gaze depth. Using the gaze depth as a trigger to select the layers has a essential advantage over using other gestures or spoken commands in the sense of...
This study addresses the problem of geometric consistency between displayed images and real scenes in augmented reality using a video see-through hand-held display or tablet. To solve this problem, we present approximated user-perspective images rendered by homography transformation of camera images. Homography approximation has major advantages not only in terms of computational costs, but also in...
