The Gaze Dialogue Model: Nonverbal Communication in HHI and HRI

Aude Billard, Nuno Ricardo Ferreira Duarte, José Santos-Victor

When humans interact with each other, eye gaze movements have to support motor control as well as communication. On the one hand, we need to fixate the task goal to retrieve visual information required for safe and precise action-execution. On the other ha ...

Transitioning with confidence during contact/non-contact scenarios

Aude Billard, Nadia Barbara Figueroa Fernandez, Seyed Sina Mirrazavi Salehian, Hsiu-Chin Lin

In this work, we propose a dynamical system based strategy for establishing a stable contact with convex shaped surfaces during non-contact/contact scenarios. A contact is called stable if the impact occurs only once and the robot remains in contact with t ...

Facing Employers and Customers: What Do Gaze and Expressions Tell About Soft Skills?

Daniel Gatica-Perez, Skanda Muralidhar, Jean-Marc Odobez, Rémy Alain Siegfried

Eye gaze and facial expressions are central to face-to-face social interactions. These behavioral cues and their connections to first impressions have been widely studied in psychology and computing literature, but limited to a single situation. Utilizing ...

Estimating Fusion Weights of a Multi-Camera Eye Tracking System by Leveraging User Calibration Data

Jean-Philippe Thiran, Nuri Murat Arar

Cross-ratio (CR)-based eye tracking has been attracting much interest due to its simple setup, yet its accuracy is lower than that of the model-based approaches. In order to improve the estimation accuracy, a multi-camera setup can be exploited rather than ...

A gaze-based learning analytics model: in-video visual feedback to improve learner's attention in MOOCs

Pierre Dillenbourg, Patrick Jermann, Kshitij Sharma, Hamed Seiied Alavi

In the context of MOOCs, “With-me-ness” refers to the extent to which the learner succeeds in following the teacher, specifically in terms of looking at the area in the video that the teacher is explaining. In our previous works, we employed eye-tracking m ...

Camera-based estimation of student's attention in class

Mirko Raca

Two essential elements of classroom lecturing are the teacher and the students. This human core can easily be lost in the overwhelming list of technological supplements aimed at improving the teaching/learning experience. We start from the question of whet ...

Gaze Analysis methods for Learning Analytics

Kshitij Sharma

Eye-tracking had been shown to be predictive of expertise, task-based success, task-difficulty, and the strategies involved in problem solving, both in the individual and collaborative settings. In learning analytics, eye-tracking could be used as a powerf ...

How Students Learn using MOOCs: An Eye-tracking Insight

Pierre Dillenbourg, Patrick Jermann, Kshitij Sharma

We present the results of an eye-tracking study on a Massive Open Online Course (MOOC) lecture showing the relation between gaze variables and students’ performance and learning strategy. 40 students watched a MOOC lecture while their eye-movements were be ...

Perception of Social Cues of Danger in Autism Spectrum Disorders

Nouchine Hadjikhani, Loyse Hippolyte, Ophélie Rogier, Torsten Ruest, Britt Russo

Intuitive grasping of the meaning of subtle social cues is particularly affected in autism spectrum disorders (ASD). Despite their relevance in social communication, the effect of averted gaze in fearful faces in conveying a signal of environmental threat ...

It's All in the Eyes: Subcortical and Cortical Activation during Grotesqueness Perception in Autism

Nouchine Hadjikhani, Loyse Hippolyte, Ophélie Rogier, Britt Russo

Atypical face processing plays a key role in social interaction difficulties encountered by individuals with autism. In the current fMRI study, the Thatcher illusion was used to investigate several aspects of face processing in 20 young adults with high-fu ...

The missing social instinct : behavioral and functional brain imaging investigations in autism

Nicole Regula Zürcher Wimmer

Smooth social interactions in everyday life rely on spontaneous understanding of emotions and intentions of others, conveyed by subtle social cues, such as gaze and facial expressions. In individuals with autism, however, who represent close to 1% of the p ...
