Predictability, efference copies, and non-retinotopic motion

Perception is usually non-retinotopic. For example, a reflector on the wheel of a bicycle is perceived to rotate on a circular orbit, while its retinotopic motion is cycloidal. To investigate non-retinotopic motion perception, we used the Ternus-Pikler dis ...

You're Doing It Wrong! Studying Unexpected Behaviors in Child-Robot Interaction

Pierre Dillenbourg, Francesco Mondada, Séverin Lemaignan, Julia Fink

We present a study on the impact of unexpected robot behaviors on the perception of a robot by children and their subsequent engagement in a playful interaction based on a novel ”domino” task. We propose an original analysis methodology which blends behavi ...

Population receptive field estimates of human auditory cortex

Melissa Saenz

Here we describe a method for measuring tonotopic maps and estimating bandwidth for voxels in human primary auditory cortex (PAC) using a modification of the population Receptive Field (pRF) model, developed for retinotopic mapping in visual cortex by Dumo ...

Obligatory averaging in mean size perception

Aire Raidvee

The perception of ensemble characteristics is often regarded as an antidote to an established bottleneck in focused attention and working memory, both of which appear to be limited in capacity to a few objects only. In order to test the associative law of ...

Exploiting Long-Term Connectivity and Visual Motion in CRF-based Multi-Person Tracking

Jean-Marc Odobez, Alexandre Heili

We present a conditional random field approach to tracking-by-detection in which we model pairwise factors linking pairs of detections and their hidden labels, as well as higher order potentials defined in terms of label costs. To the contrary of previous ...

Subjective evaluation of an active crosstalk reduction system for mobile autostereoscopic displays

Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek, Alexandre Chappuis

The Quality of Experience (QoE) provided by autostereoscopic 3D displays strongly depends on the user position. For an optimal image quality, the observer should be located at one of the relevant positions, called sweet spots, where artifacts reducing the ...

The time of perception and the perception of time are not identical

Michael Herzog

Often it is assumed that the time of perception is identical or tightly linked to the perception of time. For example, we can clearly perceive a 20 ms delay of two squares presented one after the other at nearby locations (leading to the percept of apparen ...

Visual crowding illustrates the inadequacy of local vs. global and feedforward vs. feedback distinctions in modeling visual perception

Michael Herzog, Gregory Francis, Aaron Michael Clarke

Experimentalists tend to classify models of visual perception as being either local or global, and involving either feedforward or feedback processing. We argue that these distinctions are not as helpful as they might appear, and we illustrate these issues ...

Tracing path-guided apparent motion in human primary visual cortex V1

Michael Herzog, Michel Akselrod

Vision is a constructive process. For example, a square, flashed at two distinct locations one after the other, appears to move smoothly between the two locations rather than as two separate flashes (apparent motion). Apparent motion is usually perceived a ...
