3-D Head Tracking via Invariant Keypoint Learning

Keypoint matching is a standard tool to solve the correspondence problem in vision applications. However, in 3-D face tracking, this approach is often deficient because the human face complexities, together with its rich viewpoint, nonrigid expression, and ...

Investigating the midline effect for visual focus of attention recognition

Jean-Marc Odobez, Samira Sheikhi

This paper addresses the recognition of people’s visual focus of attention (VFOA), the discrete version of gaze indicating who is looking at whom or what. In absence of high def- inition images, we rely on people’s head pose to recognize the VFOA. To the c ...

Accelerated autofocusing of off-axis holograms using critical sampling

Christian Depeursinge, Muhammed Fatih Toy, Jérôme Parent, Marcel Egli, Stéphane Richard

In this Letter we propose a fast off-axis hologram autofocusing (AF) approach that is based on the redundant data elimination by the critical resampling of the contained complex field. Implementation of the proposed methodology enables the real-time AF wit ...

A Wearable Gaze Tracking System for Children in Unconstrained Environments

Aude Billard, Basilio Noris, Jean-Baptiste Keller

We present here a head-mounted gaze tracking system for the study of visual behavior in unconstrained environments. The system is designed both for adults and for infants as young as 1 year of age. The system uses two CCD cameras to record a very wide fiel ...

A 99 Dollar Head-Mounted Eye Tracker

Pierre Dillenbourg, Frédéric Kaplan, Andrea Mazzei, Youri Marko

Head-mounted eye-trackers are powerful research tools to study attention processes in various contexts. Most existing commercial solutions are still very expensive, limiting the current use of this technology. We present a hardware design to build, at low ...

Making Mobile Augmented Reality A Reality

Jeffrey Huang, Hendrik Ole Knoche, Laurent Bindschaedler

Recent advances in mobile device technology have freed augmented reality (AR) applications from the constraints of desktops, laptops and head-mounted displays. But they are met with a lack of guidelines on the design and user interactions of mobile device- ...

Measuring Gaze of Children with Autism Spectrum Disorders in Naturalistic Interactions

Aude Billard, Basilio Noris

In this paper, we report on a study on gaze behavior by children with Autism Spectrum Disorder (ASD) during a dyadic interaction in a naturalistic environment. Twelve children with ASD were contrasted to twelve typically developing (TD) children, in a semi ...

Producing and Reading Annotations on Paper Documents: a geometrical framework for eye-tracking studies

Pierre Dillenbourg, Frédéric Kaplan, Andrea Mazzei

The printed textbook remains the primary medium for studying in educational systems. Learners use personal annotation strategies while reading. These practices play an important role in supporting working memory, enhancing recall and influencing attentiona ...
