Easy and Flexible Calibration Approach for Deflectometry-Based VR-Eye Tracking Systems (CTh5C.1)
Presenter: Jiazhang Wang, Northwestern University

We present an easy and flexible calibration approach for small field of view Deflectometry systems to be used in VR headsets. Our method replaces all required calibration targets and mirrors with a small (phone) screen to perform intrinsic and extrinsic camera calibration as well as geometric calibration of the whole setup.

Time-Multiplexed Methods for Head-Mounted Light Field Displays (CTh5C.2)
Presenter: Hong Hua, University of Arizona

Conventional integral-imaging based light field displays are often subject to the tradeoffs among spatial resolution, view density, and depth of field. In this paper, I will review several time-multiplexed methods we recently explored for creating high-performance head-mounted light field displays (LF-HMD).

Disparity Reconstruction From Light Field's Multidirectional EPIs With Kalman Filter (CTh5C.3)
Presenter: Chang Liu, Beijing Information Science and Technology University

We modeled the generation of multidirectional Epipolar Plane Images (EPIs) as a linear dynamical system. Then we proposed a framework of disparity reconstruction from the multidirectional EPIs with Kalman filter to achieve anti-occlusion and anti-noise.

(Withdrawn) Perceptually Guided Next-Generation Displays (CTh5C.4)
Presenter: Kaan Aksit, University College London

We spend a tremendous amount of time in front of our screens. This talk will explore a path towards next-generation displays. The key to this research is designing display hardware that fits our visual perception.
