Voluntary facial activations regulate physiological arousal and subjective experiences during virtual social stimulation
Vanhala T., Surakka V., Courgeon M., Martin J. ACM Transactions on Applied Perception 9(1): 1-21, 2012. Type: Article
In recent years, computer simulations have been used to desensitize people suffering from a variety of phobias or generalized social anxiety. This paper describes experiments to assess the effectiveness of using voluntary facial gestures during...

Evaluating 2D and 3D visualizations of spatiotemporal information
Kjellin A., Pettersson L., Seipel S., Lind M. ACM Transactions on Applied Perception 7(3): 1-23, 2010. Type: Article
Kjellin et al. examine how several test subjects interpret and predict the eventual outcomes of three visualization experiments. They created 2D and 3D maps of a fictitious landscape, using tracks to show the progress of vehicles. The object was...

Pointing in pictorial space: quantifying the perceived relative depth structure in mono and stereo images of natural scenes
Wijntjes M., Pont S. ACM Transactions on Applied Perception 7(4): 1-8, 2010. Type: Article
Stereopsis is the process of creating a three-dimensional (3D) illusion based on two slightly different projections of a scene. Each projection is projected onto one eye. This effect, exploited in photographic images since the 19th century and,...

Visually significant edges
Aydin T., Čadík M., Myszkowski K., Seidel H. ACM Transactions on Applied Perception 7(4): 1-15, 2010. Type: Article
Although edge detection has been the subject of extensive work for many years, it is still not difficult to find or manufacture images where the edge picture produced by current methods is visually unsatisfying. Human observers have a...

Investigating the role of body shape on the perception of emotion
McDonnell R., Jörg S., McHugh J., Newell F., O’Sullivan C. ACM Transactions on Applied Perception 6(3): 1-11, 2009. Type: Article
Virtual characters are used extensively in movies and games, but the effect of both motion and body shape on the portrayal of basic human emotions remains poorly understood. Some suggest that the more anthropomorphic a virtual character is, the...

Spatial learning and navigation using a virtual verbal display
Giudice N., Bakdash J., Legge G., Roy R. ACM Transactions on Applied Perception 7(1): 1-22, 2010. Type: Article
The virtual learning environment has been an effective tool for the learning process; it continues to gain importance, with gradual improvements in technology, tools, and methods with a special focus on information technology. User behavior, user ...

Using virtual environments to assess time-to-contact judgments from pedestrian viewpoints
Seward A., Ashmead D., Bodenheimer B. ACM Transactions on Applied Perception 4(3): 18-es, 2007. Type: Article
Based on the time-to-contact (TTC) estimation of approaching vehicles, a pedestrian makes the street-crossing decisions. People estimate TTC through a very complicated process, and most parts of this judgment process are still unknown to...

Obstacle avoidance during walking in real and virtual environments
Fink P., Foo P., Warren W. ACM Transactions on Applied Perception 4(1): 2-es, 2007. Type: Article
In the quest for quantitative and qualitative parameters that would characterize the differences (or similarities) in human actions in the real and virtual world, Fink, Foo, and Warren present a study of human performance in obstacle avoidance....

An application of eyegaze tracking for designing radiologists’ workstations: insights for comparative visual search tasks
Atkins M., Moise A., Rohling R. ACM Transactions on Applied Perception 3(2): 136-151, 2006. Type: Article
Radiologists must examine patient images quickly and accurately. The user interface for radiologists’ workstations can either help or hinder the effectiveness of this diagnostic tool. Atkins, Moise, and Rohling describe a study that...

A study of level-of-detail in haptic rendering
Payandeh S., Dill J., Zhang J. ACM Transactions on Applied Perception 2(1): 15-34, 2005. Type: Article
Haptic feedback is becoming more and more common in the visual simulation of various critical tasks. To this end, the physical properties of the underlying material need to be measured or evaluated, and used to simulate the forces applied to the...
