A unified information-theoretic framework for viewpoint selection and mesh saliency
Miquel Feixas, Mateu Sbert, Francisco González
Article No.: 1
Viewpoint selection is an emerging area in computer graphics with applications in fields such as scene exploration, image-based modeling, and volume visualization. In particular, best view selection algorithms are used to obtain the minimum number...
A psychophysical investigation of global illumination algorithms used in augmented reality
Timothy J. Hattenberger, Mark D. Fairchild, Garrett M. Johnson, Carl Salvaggio
Article No.: 2
The overarching goal of this research was to compare different rendering solutions in order to understand why some yield better results specifically when applied to rendering synthetic objects into real photographs. A psychophysical experiment was...
Negative efficacy of fixed gain error reducing shared control for training in virtual environments
Yanfang Li, Volkan Patoglu, Marcia K. O'Malley
Article No.: 3
Virtual reality with haptic feedback provides a safe and versatile practice medium for many manual control tasks. Haptic guidance has been shown to improve performance of manual control tasks in virtual environments; however, the efficacy of...
The spatial resolution of crossmodal attention: Implications for the design of multimodal interfaces
Rob Gray, Rayka Mohebbi, Hong Z. Tan
Article No.: 4
Previous research on crossmodal attentional orienting has reported speeded reaction times (RT) when the stimuli from the different modalities are in the same spatial location and slowed RTs when the stimuli are presented in very different...
We examined human perception of head-referenced image motion during concurrent head movement. The visual stimulus was a checkerboard image in a head mounted display that moved from side-to-side. Observers rated the magnitude of the checkerboard...
Classifying pretended and evoked facial expressions of positive and negative affective states using infrared measurement of skin temperature
Masood Mehmood Khan, Robert D. Ward, Michael Ingleby
Article No.: 6
Earlier researchers were able to extract the transient facial thermal features from thermal infrared images (TIRIs) to make binary distinctions between the expressions of affective states. However, effective human-computer interaction would...
