A Comparative Perceptual Study of Soft-Shadow Algorithms
Michael Hecher, Matthias Bernhard, Oliver Mattausch, Daniel Scherzer, Michael Wimmer
Article No.: 5
DOI: 10.1145/2620029

We performed a perceptual user study of algorithms that approximate soft shadows in real time. Although a huge body of soft-shadow algorithms have been proposed, to our knowledge this is the first methodical study for comparing different real-time...

Olfactory Adaptation in Virtual Environments
Belma Ramic-Brkic, Alan Chalmers
Article No.: 6
DOI: 10.1145/2617917

Visual perception is becoming increasingly important in computer graphics. Research on human visual perception has led to the development of perception-driven computer graphics techniques, where knowledge of the human visual system (HVS) and, in...

Human Perception of Visual Realism for Photo and Computer-Generated Face Images
Shaojing Fan, Rangding Wang, Tian-Tsong Ng, Cheston Y.-C. Tan, Jonathan S. Herberg, Bryan L. Koenig
Article No.: 7
DOI: 10.1145/2620030

Computer-generated (CG) face images are common in video games, advertisements, and other media. CG faces vary in their degree of realism, a factor that impacts viewer reactions. Therefore, efficient control of visual realism of face images is...

A New Hypothesis on Facial Beauty Perception
Fangmei Chen, Yong Xu, David Zhang
Article No.: 8
DOI: 10.1145/2622655

In this article, a new hypothesis on facial beauty perception is proposed: the weighted average of two facial geometric features is more attractive than the inferior one between them. Extensive evidences support the new hypothesis. We collected...

Towards the Temporally Perfect Virtual Button: Touch-Feedback Simultaneity and Perceived Quality in Mobile Touchscreen Press Interactions
Topi Kaaresoja, Stephen Brewster, Vuokko Lantz
Article No.: 9
DOI: 10.1145/2611387

Pressing a virtual button is still the major interaction method in touchscreen mobile phones. Although phones are becoming more and more powerful, operating system software is getting more and more complex, causing latency in interaction. We were...

Perceptual Evaluation of Motion Editing for Realistic Throwing Animations
Michele Vicovaro, Ludovic Hoyet, Luigi Burigana, Carol O'sullivan
Article No.: 10
DOI: 10.1145/2617916

Animation budget constraints during the development of a game often call for the use of a limited set of generic motions. Editing operations are thus generally required to animate virtual characters with a sufficient level of variety. Evaluating...
