Affine Geometry, Visual Sensation, and Preference for Symmetry of Things in a Thing
Birgitta Dresp-Langley
Evolution and geometry generate complexity in similar ways. Evolution drives natural selection while geometry may capture the logic of this selection and express it visually, in te…
Colour for behavioural success
Birgitta Dresp-Langley, Adam Reeves
Colour information not only helps sustain the survival of animal species by guiding sexual selection and foraging behaviour, but also is an important factor in the cultural and tec…
Principles of perceptual grouping: implications for image-guided surgery
Birgitta Dresp-Langley
Gestalt theory has provided perceptual science with a conceptual framework which has inspired researchers ever since, taking the field of perceptual organization into the 21st cent…
Wayfinding through an unfamiliar environment
Yasmine Boumenir, Fanny Georges, Jeremy Valentin +2
Strategies for finding one's way through an unfamiliar environment may be helped by computer generated 2D maps, 3D virtual environments, or other navigation aids. The relative effe…
Why the brain knows more than we do: non-conscious representations and their role in the construction of conscious experience
Birgitta Dresp-Langley
Scientific studies have shown that non-conscious stimuli and representations influence information processing during conscious experience. In the light of such evidence, questions…
Neural computation of surface border ownership and relative surface depth from ambiguous contrast inputs
Birgitta Dresp-Langley, Stephen Grossberg
The segregation of image parts into foreground and background is an important aspect of the neural computation of 3D scene perception. To achieve such segregation, the brain needs…
Visual spatial learning of complex object morphologies through interaction with virtual and real-world data
Chiara Silvestri, Rene Motro, Bernard Maurin +1
Conceptual design relies on extensive manipulation of morphological properties of real or virtual objects.This study investigates the nature of the perceptual information that coul…
Seeing virtual while acting real: Visual display and strategy effects on the time and precision of eye-hand coordination
A. U. Batmaz, M. de Mathelin, Birgitta Dresp-Langley
Effects of computer generated 2D and 3D views on the time and precision of bare-handed or tool-mediated eye-hand coordination were investigated in a pick-and-place-task with comple…
Effects of 2D and 3D image views on hand movement trajectories in the surgeons peripersonal space in a computer controlled simulator environment
AU Batmaz, M de Mathelin, Birgitta Dresp-Langley
In image-guided surgical tasks, the precision and timing of hand movements depend on the effectiveness of visual cues relative to specific target areas in the surgeons peri-persona…
Getting nowhere fast: trade-off between speed and precision in training to execute image-guided hand-tool movements
AU Batmaz, M de Mathelin, Birgitta Dresp-Langley
Background: The speed and precision with which objects are moved by hand or hand-tool interaction under image guidance depend on a specific type of visual and spatial sensorimotor…
Detection of Structural Change in Geographic Regions of Interest by Self Organized Mapping: Las Vegas City and Lake Mead across the Years
John M. Wandeto, Henry O. Nyongesa, Birgitta Dresp-Langley
Time-series of satellite images may reveal important data about changes in environmental conditions and natural or urban landscape structures that are of potential interest to citi…
