Quality assessment of images presented on a high frame rate OLED display

High frame rate displays can render motion more smoothly. We evaluated the quality of motion rendered on a state-of-the-art OLED display with a natural frame rate of 240Hz. In addition, we also tested the visibility of flicker on various display modes implemented in the display. [more]

Characterizing color breakup in color-sequential displays

Many displays including DLP projectors present red, green, and blue colors sequentially in time. Even with a very high frame rate (e.g. 180Hz), such displays can have color artifacts. We characterized when and how color artifacts occur and how we can minimize them. [more]

Visual discomfort in stereoscopic 3D displays: vergence-accommodation conflict

Vergence cue and focal cue agree in natural environments, but not in stereoscopic 3D displays: vergence cue varies depending on the binocular disparity in contents while focal cue is fixed at screen distance. We evaluated how the inconsistency between vergence and focal cues affects viewer discomfort. [more]

Measuring resolution of stereoscopic 3D displays

Temporal interlacing (or active type) stereoscopic 3D displays show one eye's view at a time, while spatial interlacing (or passive type) stereoscopic 3D displays show both eyes' views on every other row. In this project, we measured the effective resolution of these two methods from the perspective of human viewers. [more]

Color interlacing 3D with improved depth perception

This novel stereo 3D presentation protocol shows G from the left view and R and B from the right view during subframe 1 and R and B from the left view and G from the right view during subframe 2. The proposed protocol can be implemented by using a set of narrow-band filters, and more significantly improves depth perception. [more]

Spatio-temporal hybrid stereoscopic 3D displays

Some stereo 3D presentation methods have their own shortcomings. Temporal interlacing manifests distortion in perceived depth while spatial interlacing has lower effective resolution. We propose a spatio-temporal hybrid presentation method that eliminates the drawbacks of both methods. [more]

Integral floating: an immersive multi-view 3D displays

An integral floating system consists of an integral imaging (light field) display, which forms a 3D image, and a large convex lens, which broadcasts it to the viewer. I optimized the spatial arrangement of the system components to maximize its viewing angle. [more]
