This document outlines a course on glasses-free 3D displays. It begins with an introduction to the history and physiology of depth perception, including monocular cues like motion parallax and accommodation, as well as binocular cues like retinal disparity and convergence. It then covers constructing glasses-free 3D displays using multi-view rendering and interlacing techniques. The course also addresses designing content for these displays and emerging technologies in the field. It provides examples of early 3D viewing devices and stereoscopic photographs throughout history to illustrate the concepts.

14. Physiology of Depth Perception Another Monocular Cue Accommodation Binocular Cues Convergence Stereopsis This is the cue added by 3D displays covered in this course The brain determines depth by observing the scene disparity between two viewpoints Can simulate this depth cue by multiplexing a different synthetic image to each eye These effects are due to physical functions of the eye, and not interpretation of the scene

15. Conflicting Cues The HVS can ignore conflicting or missing depth cues Understand depth in 2D (monocular) video Perceive shape in “noise” magiceye.com Ponzo Illusion: © Walt Anthony 2006

16. Missing Binocular Cues Ponzo Illusion We perceive depth without binocular cues Depth perception changes perception of line length
