Exploring the Extent in the Visual Field of the Honeycomb and Extinction Illusions

Michael Herzog, Aline Françoise Cretenoud

There are situations in which what is perceived in central vision is different to what is perceived in the periphery, even though the stimulus display is uniform. Here, we studied two cases, known as the Extinction illusion and the Honeycomb illusion, invo ...

Visual Distortions in 360-degree videos (Dataset)

Pascal Frossard, Francesca De Simone, Roberto Gerson De Albuquerque Azevedo

Here we catalog, visually demonstrate, and discuss the main causes of commonly encountered visual distortions into current 360-degree video processing pipelines. The main goal of the samples in this dataset is to demonstrate the visual distortions discusse ...

About specific and general factors for visual illusions

Michael Herzog, Gregory Francis, Lukasz Grzeczkowski, Aline Françoise Cretenoud

Contrary to studies of audition and cognition, we previously did not find evidence for a general common factor for vision but for many very specific ones. For example, we found strong correlations between 19 versions of the Ebbinghaus illusion, which diffe ...

Perception of visual illusions is intact in schizophrenia

Michael Herzog, Maya Roinishvili, Lukasz Grzeczkowski, Albulena Jashari-Shaqiri

There seems to be no common factor for visual perception because performance levels in many visual tasks correlate only weakly with each other. Similar results were found with visual illusions. However, one may expect common visual factors for individuals ...

Is the perception of illusions abnormal in schizophrenia?

Michael Herzog, Maya Roinishvili, Lukasz Grzeczkowski, Albulena Jashari-Shaqiri

There seems to be no common factor for visual perception, i.e., performance in visual tasks correlates only weakly with each other. Similar results were found with visual illusions. One may expect common visual factors for individuals suffering from pathol ...

The individual structure of visual space

Michael Herzog, Gregory Francis, Lukasz Grzeczkowski, Albulena Jashari-Shaqiri, Aline Françoise Cretenoud

Common factors are ubiquitous. First, we show that, however in vision, correlations of performance in similar paradigms are low even though test-retest reliability is high. Second, one might expect that correlations increase with increasing age because of ...

Modulation of vection latencies in the full-body illusion

Olaf Blanke, Bruno Herbelin, Giulio Rognini, Alessandro Nesti

Current neuroscientific models of bodily self-consciousness (BSC) argue that inaccurate integration of sensory signals leads to altered states of BSC. Indeed, using virtual reality technology, observers viewing a fake or virtual body while being exposed to ...

Optoelectronic and/or electrochemical learning device

Michael Graetzel, Hoi Nok Tsao

The present invention concerns photoelectronic and/or optoelectronic learning device and/or memory device. In an embodiment, the device is a dye- sensitized solar cell. The short circuit photocurrent density (Jsc) of the device, and wherein a degree of a J ...

The Architectonic Experience of Body and Space in Augmented Interiors

Olaf Blanke, Andrea Serino, Isabella Maria Pasqualini, Maria Laura Blefari

The environment shapes our experience of space in constant interaction with the body. Architectonic interiors amplify the perception of space through the bodily senses; an effect also known as embodiment. The interaction of the bodily senses with the space ...

How many factors are there in vision?

Michael Herzog, Gregory Francis, Lukasz Grzeczkowski, Aline Françoise Cretenoud

Common factors are ubiquitous in cognition, audition, and somato-sensation. Surprisingly, there seems to be no common factor in vision, i.e., visual tasks correlate very weakly with each other. Here, we show that there are likely many very specific factors ...
