From retinotopic processing to nonretinotopic representation

Marc Michael Lauffs

Encoding of visual information in the brain is retinotopic: Neighboring points in the visual field are mapped onto neighboring photoreceptors in the retina, and these neighborhood relations are maintained in the early stages of cortical processing. However ...

Light-driven model for identifying indicators of non-visual health potential in the built environment

María Lovísa Ámundadóttir

This thesis introduces a new approach to characterize and evaluate ocular light exposure based on the discovery of novel blue light-sensitive photoreceptors in the human eye. These photoreceptors are the primary mediators of 'non-visual' responses impactin ...

Method and apparatus for head worn display with multiple exit pupils

Christophe Moser, Eric Tremblay

A method for displaying an image viewable by an eye, the image being projected from a portable head worn display, comprises steps of: emitting a plurality of light beams of wavelengths that differ amongst the light beams; directing the plurality of light b ...

Visuomotor Coordination in Reach-To-Grasp Tasks: From Humans to Humanoids and Vice Versa

Luka Lukic

Understanding the principles involved in visually-based coordinated motor control is one of the most fundamental and most intriguing research problems across a number of areas, including psychology, neuroscience, computer vision and robotics. Not very much ...

Motor-Primed Visual Attention for Humanoid Robots

Aude Billard, Luka Lukic, José Santos-Victor

We present a novel, biologically inspired, approach to an efficient allocation of visual resources for humanoid robots in a form of a motor-primed visual attentional landscape. The attentional landscape is a more general, dynamic and a more complex concept ...

Pupil responses derived from outer and inner retinal photo reception are normal in patients with hereditary optic neuropathy

Mirjam Münch, Lorette Leon

We compared the pupil responses originating from outer versus inner retinal photoreception between patients with isolated hereditary optic neuropathy (HON, n = 8) and healthy controls (n = 8). Three different testing protocols were used. For the first two ...

Ultra-Eye: UHD and HD images eye tracking dataset

Touradj Ebrahimi, Philippe Hanhart, Hiromi Nemoto

Due to the recent advances in ultra high definition (UHD) displays, UHD TV may replace HD TV in a near future. However, little is known about the effect of UHD content on human visual perception, specifically, on human visual attention, viewing strategies, ...

Attention Driven Foveated Video Quality Assessment

Touradj Ebrahimi

Contrast sensitivity of the human visual system to visual stimuli can be significantly affected by several mechanisms, e. g., vision foveation and attention. Existing studies on foveation based video quality assessment only take into account static foveati ...

EyeC3D: 3D video eye tracking dataset

Touradj Ebrahimi, Philippe Hanhart

Despite efforts of the scientific community in recent years, little is known about the mechanisms of the human visual system that control visual attention when watching 3D content. To help understanding these mechanisms and develop more accurate visual att ...

A polymer-based interface restores light sensitivity in blind rats

Diego Ghezzi

Progressive degeneration of photoreceptors is one of the major causes of adult blindness in “industrialized” countries; as an example, Retinitis pigmentosa defines a set of monogenic hereditary retinal diseases, with a prevalence of 1:4000 worldwide, cause ...
