Audio-Visual Object Classification For Human-Robot Collaboration

Human-robot collaboration requires the contactless estimation of the physical properties of containers manipulated by a person, for example while pouring content in a cup or moving a food box. Acoustic and visual signals can be used to estimate the physica ...

Comic Based Learning for Students with Visual Impairments

Visual impairment can affect a student's ability to learn since their concept development when interacting with educational material is being limited. Learning activities based on images and visually rich content are mainstream learning methods, where faci ...

How do visual skills relate to action video game performance?

Michael Herzog, Aline Françoise Cretenoud, Oh-Hyeon Choung, Arthur Barakat

It has been claimed that video gamers possess increased perceptual and cognitive skills compared to non-video gamers. Here, we examined to which extent gaming performance in CS:GO (Counter-Strike: Global Offensive) correlates with visual performance.We tes ...

Photovoltaic stimulation of retinal microcircuit for vision restoration

Naïg Aurelia Ludmilla Chenais

Sight restoration through retinal prostheses was still a mere dream a century ago. Current challenges are even greater: providing a quantitatively and qualitatively useful artificial vision to late blind patients. Existing approaches all face engineering a ...

Individual differences in the perception of visual illusions are stable across eyes, time, and measurement methods

Michael Herzog, Aline Françoise Cretenoud, Lukasz Grzeczkowski

Vision scientists have tried to classify illusions for more than a century. For example, some studies suggested that there is a unique common factor for all visual illusions. Other studies proposed that there are several subclasses of illusions, such as il ...

OCT-angiography assessing quiescent and active choroidal neovascularization in retinitis pigmentosa associated with PRPH2 pathogenic variant

Imen Habibi

Purpose: To report multimodal imaging findings including optical coherence tomography angiography (OCT-A) of a patient presenting with a quiescent choroidal neovascularization (CNV) in one eye and an active CNV in the fellow eye, complicating retinitis pig ...

About common factors in vision

Michael Herzog, Aline Françoise Cretenoud, Simona Adele Garobbio, Maya Roinishvili, Lukasz Grzeczkowski, Ophélie Gladys Favrod, Janir Nuno Ramos Antunes Da Cruz, Dario Alejandro Gordillo Lopez

Often, we intuitively assume that there are common factors in life. For example, we test people with a visual acuity test to determine whether they are allowed to drive a car or not- with the implicit assumption that the acuity test is representative of vi ...

A machine-learning algorithm correctly classifies cortical evoked potentials from both visual stimulation and electrical stimulation of the optic nerve

Diego Ghezzi, Eleonora Borda, Vivien Gaillet, Elodie Geneviève Zollinger

Objective. Optic nerve's intraneural stimulation is an emerging neuroprosthetic approach to provide artificial vision to totally blind patients. An open question is the possibility to evoke individual non-overlapping phosphenes via selective intraneural op ...

Enhancing visual motion discrimination by desynchronizing bifocal oscillatory activity

Friedhelm Christoph Hummel, Estelle Emeline Raffin, Roberto Felipe Salamanca Giron, Sarah Bernardina Zandvliet, Martin Seeber

Visual motion discrimination involves reciprocal interactions in the alpha band between the primary visual cortex (V1) and mediotemporal areas (V5/MT). We investigated whether modulating alpha phase synchronization using individualized multisite transcrani ...

Serial dependence does not originate from low-level visual processing

Michael Herzog, David Pascucci, Gizay Ceylan

Perception depends not only on the current sensory input but also on the preceding history of stimuli. In serial dependence (SD), for example, the orientation of a Gabor patch is mistakenly reported as more similar to previous trials than it actually is. T ...
