Uncanny Valley and Animation Research

 

I examined how viewers perceive real and animated facial and vocal expressions.

Modeling and Animating Eye Blinks

Animated blinks generated from the human data model with fully closing eyelids are consistently perceived as more natural than those created using the various types of blink dynamics proposed in animation textbooks.

Voice Synchronization in Film

When temporal synchronization is noticeably absent, there is a decrease in the perceived performance quality and the perceived emotional intensity of a performance.

Viewing Patterns for Animated Faces

Viewers look slightly longer at faces of animated characters that they find unpleasant.

Posed and Spontaneous Smile Dynamics

Both space and time linearizations impact the perceived genuineness of posed and spontaneous smiles.

A Perceptual Control Space for Garment Simulation

We created a perceptual control space for simulation of cloth that provides intuitive, art-directable control over the simulation behavior based on a learned mapping from common discriptors for cloth to the parameters of the simulation.
