An Empirical Investigation of the Determinants of Attention to Attributes in Choice Experiments

Recent results showed that taking into account attention to attributes in random utility models leads to better fitting models. In this paper, we study a proposition to model attention to attributes instead of monitoring it. We test this model considering ...

Investigating the use of Visual Focus of Attention for Audio-Visual Speaker Diarisation

Hervé Bourlard, Jean-Marc Odobez, Silèye Oumar Ba

Audio-visual speaker diarisation is the task of estimating ``who spoke when'' using audio and visual cues. In this paper we propose the combination of an audio diarisation system with psychology inspired visual features, reporting experiments on multiparty ...

Using Visual Attention to Evaluate Collaborative Control Architectures for Human Robot Interaction

Tom Edward Carlson

Collaborative control architectures assist human users in performing tasks, without undermining their capabilities or curtailing the natural development of their skills. In this study, we evaluate our collaborative control architecture by investigating the ...

Control of Attention to Mental States and Multiple Critics

Arash Arami

Attentional modulation is needed when a decision maker is faced with too much information to process. In this paper we discuss the use of attention in control applications where usually higher order system dynamics are involved as typical benchmarks consid ...

Fast Hand Gesture Recognition based on Saliency Maps: An Application to Interactive Robotic Marionette Playing

Mostafa Ajallooeian

In this paper, we propose a fast algorithm for gesture recognition based on the saliency maps of visual attention. A tuned saliency-based model of visual attention is used to find potential hand regions in video frames. To obtain the overall movement of th ...

Modulation of Attentional Capture by Display Probabilities in Visual Search

Michael Herzog, Bilge Sayim

Attentional capture is often thought to be automatic and not modulable. For example, visual search experiments showed that salient distractor singletons strongly capture attention even when they had to be ignored by the observers. Recently, however, it was ...

Non-retinotopic feature integration decreases response-locked brain activity as revealed by electrical neuroimaging

Michael Herzog, Olaf Blanke, Gijs Plomp, Thomas Otto, Manuel Mercier

When presented with dynamic scenes, the brain integrates visual elements across space and time. Such non-retinotopic processing has been intensively studied from a psychophysical point of view, but little is known about the underlying neural processes. Her ...

Simulating gaze attention behaviors for crowds

Daniel Thalmann, Helena Stephanie Grillon Le Gallennec

Crowd animation is a topic of high interest which offers many challenges. One of the most important is the trade-off between rich, realistic behaviors, and computational costs. To this end, much effort has been put into creating variety in character repres ...

Spatial grouping determines temporal integration

Michael Herzog, Frank Scharnowski

To make sense out of a continuously changing visual world, people need to integrate features across space and time. Despite more than a century of research, the mechanisms of features integration are still a matter of debate. To examine how temporal and sp ...

Temporal integration in visual word recognition

Joachim Jean-Marie Forget

When two displays are presented in close temporal succession at the same location, how does the brain assign them to one versus two conscious percepts? We investigate this issue using a novel reading paradigm in which the odd and even letters of a string a ...
