Summary: We present Vortex, an architecture for live-streaming 3D virtual reality video. Vortex uses two fast line sensors combined with wide-angle lenses, spinning at up to 300 rpm, to directly capture stereoscopic 360-degree virtual reality video in the widely-used omni-directional stereo (ODS) format.

Summary: A method to reproduce realistic depth-dependent blur. The human eye has chromatic aberration, which produces depth-dependent chromatic effects. We calculate rendered images that, when processed by the viewer's in-focus eye, will produce the correct chromatic effects on the viewer's retina for the simulated 3d scene.

Summary: Virtual reality applications prefer real walking to provide highly immersive presence than other locomotive methods. In this paper, we present a novel divide-and-conquer method, called smooth assembly mapping (SAM), to compute real walking mappings with low isometric distortion for large-scale virtual scenes.

Summary: We present a fully perceptual-based head related transfer function (3d audio spatialization) fitting method for individual users using an adaptive variational autoencoder. The user only needs to answer pairwise comparisons of test signals presented by the system. This reduces the efforts necessary to obtain individualized HRTFs.
