Emulating Autostereoscopic Lenticular Designs

Abstract

Optimizing performance of autostereoscopic lenticular displays can be achieved by altering specific interdependent design parameters, e.g., width and number of views, screen disparity and lenticular slant, resulting in different crosstalk distributions and amounts of banding and consequently, different percepts. To allow the evaluation of an autostereoscopic lenticular display, before a costly physical sample is produced, an emulator was build. This emulator consisted of a goggle-based striped polarized display, a camera-based head tracker and software for generating L/R stereo pairs in real-time as a function of head-location. This paper addresses the development of the emulator, its validation with respect to an existing physical prototype, and the perceptual evaluation of three emulated fundamental design extremes: 1) a 9-view low-cross-talk system; 2) a 9-view intermediate crosstalk system; and 3) a 17-view high crosstalk system.
