Modeling locomotor control: The advantages of mobile gaze
Richard M. Wilkie, John P. Wann, Robert S. Allison
Article No.: 9
DOI: 10.1145/1870076.1870077

In 1958, JJ Gibson put forward proposals on the visual control of locomotion. Research in the last 50 years has served to clarify the sources of visual and nonvisual information that contribute to successful steering, but has yet to determine how...

Perceptual effects of scene context and viewpoint for virtual pedestrian crowds
Cathy Ennis, Christopher Peters, Carol O'Sullivan
Article No.: 10
DOI: 10.1145/1870076.1870078

In this article, we evaluate the effects of position, orientation, and camera viewpoint on the plausibility of pedestrian formations. In a set of three perceptual studies, we investigated how humans perceive characteristics of virtual crowds in...

Perception-motivated interpolation of image sequences
Timo Stich, Christian Linz, Christian Wallraven, Douglas Cunningham, Marcus Magnor
Article No.: 11
DOI: 10.1145/1870076.1870079

We present a method for image interpolation that is able to create high-quality, perceptually convincing transitions between recorded images. By implementing concepts derived from human vision, the problem of a physically correct image...

Do predictions of visual perception aid design?
Ruth Rosenholtz, Amal Dorai, Rosalind Freeman
Article No.: 12
DOI: 10.1145/1870076.1870080

Understanding and exploiting the abilities of the human visual system is an important part of the design of usable user interfaces and information visualizations. Designers traditionally learn qualitative rules of thumb for how to enable quick,...

Object selection in gaze controlled systems: What you don't look at is what you get
Anke Huckauf, Mario H. Urbina
Article No.: 13
DOI: 10.1145/1870076.1870081

Controlling computers using eye movements can provide a fast and efficient alternative to the computer mouse. However, implementing object selection in gaze-controlled systems is still a challenge. Dwell times or fixations on a certain object...

An other-race effect for face recognition algorithms
P. Jonathon Phillips, Fang Jiang, Abhijit Narvekar, Julianne Ayyad, Alice J. O'Toole
Article No.: 14
DOI: 10.1145/1870076.1870082

Psychological research indicates that humans recognize faces of their own race more accurately than faces of other races. This “other-race effect” occurs for algorithms tested in a recent international competition for state-of-the-art...

Human-inspired search for redundancy in automatic sign language recognition
Gineke A. Ten Holt, Andrea J. Van Doorn, Marcel J. T. Reinders, Emile A. Hendriks, Huib De Ridder
Article No.: 15
DOI: 10.1145/1870076.1870083

Human perception of sign language can serve as inspiration for the improvement of automatic recognition systems. Experiments with human signers show that sign language signs contain redundancy over time. In this article, experiments are conducted...
