Feel Effects: Enriching Storytelling with Haptic Feedback
Ali Israr, Siyan Zhao, Kaitlyn Schwalje, Roberta Klatzky, Jill Lehman
Article No.: 11
DOI: 10.1145/2641570

Despite a long history of use in communication, haptic feedback is a relatively new addition to the toolbox of special effects. Unlike artists who use sound or vision, haptic designers cannot simply access libraries of effects that map cleanly to...

Spatial and Temporal Linearities in Posed and Spontaneous Smiles
Laura C. Trutoiu, Elizabeth J. Carter, Nancy Pollard, Jeffrey F. Cohn, Jessica K. Hodgins
Article No.: 12
DOI: 10.1145/2641569

Creating facial animations that convey an animator’s intent is a difficult task because animation techniques are necessarily an approximation of the subtle motion of the face. Some animation techniques may result in linearization of the...

Can I Recognize My Body's Weight? The Influence of Shape and Texture on the Perception of Self
Ivelina V. Piryankova, Jeanine K. Stefanucci, Javier Romero, Stephan De La Rosa, Michael J. Black, Betty J. Mohler
Article No.: 13
DOI: 10.1145/2641568

The goal of this research was to investigate women's sensitivity to changes in their perceived weight by altering the body mass index (BMI) of the participants' personalized avatars displayed on a large-screen immersive display. We created the...

Gaze-to-Object Mapping during Visual Search in 3D Virtual Environments
Matthias Bernhard, Efstathios Stavrakis, Michael Hecher, Michael Wimmer
Article No.: 14
DOI: 10.1145/2644812

Stimuli obtained from highly dynamic 3D virtual environments and synchronous eye-tracking data are commonly used by algorithms that strive to correlate gaze to scene objects, a process referred to as gaze-to-object mapping (GTOM). We...

Stereo Day-for-Night: Retargeting Disparity for Scotopic Vision
Petr Kellnhofer, Tobias Ritschel, Peter Vangorp, Karol Myszkowski, Hans-Peter Seidel
Article No.: 15
DOI: 10.1145/2644813

Several approaches attempt to reproduce the appearance of a scotopic low-light night scene on a photopic display (“day-for-night”) by introducing color desaturation, loss of acuity, and the Purkinje shift toward blue colors. We argue...
