Push it Real: Perceiving Causality in Virtual Interactions

This paper studies factors that affect perception of causality in virtual human interactions (for example, the impression that the action of one individual causes an appropriate reaction in another) and investigates force perception and the perceptual impact of temporal, physical, and angular distortions during interactions.

Render Me Real? Investigating the Effect of Render Style on the Perception of Animated Virtual Humans

There have been mixed reactions from audiences to lifelike characters used in movies and games, with some saying that the increased realism highlights subtle imperfections. This paper investigates some of the consequences of choosing realistic or stylized rendering styles in order to provide guidelines for creating plausible virtual characters.

Highlight Microdisparity for Improved Gloss Depiction

A method for depiction of specularities in stereoscopic 3D, which provides a compromise between fully physical highlights (potentially problematic) and flat (simple but less realistic).

Binocular Tone Mapping

This paper proposes a binocular tone-mapping framework to generate a LDR image pair that preserves more visual richness and can be visualized with standard stereo display devices. To avoid the visual discomfort due to the difference of two views, the paper proposes a novel metric based on ophthalmological findings.

Surface Flows for Image-Based Shading Design

This paper shows how to produce convincing shadings by relying on image deformations instead of complex simulation of light transport. The method performs a differential analysis of reflected radiance and then uses the findings to introduce image operators that approximate surface flows while providing the direct creation of appearance.
