Pattern codes for perceived gaze direction revealed by functional MRI
Perceiving the direction of another's attention is a critical component of normal social behaviour. Seminal electrophysiology studies demonstrated that single cells in macaque superior temporal sulcus (STS) are tuned to specific directions of social cues, including gaze direction, head view, and …

Are you looking at me? About the perception of direct gaze and gaze direction
… innovative learnings on the area of direct gaze (i.e., the range of gazes within which an observer feels looked at). It discusses valid methods to assess the area of direct gaze, the nature of its shape, and whether it is comparable to other social gestures. Previous work focused on the …

The role of social cues in the involuntary attribution of intentionality.
… head has rotated are influenced by the perceived gaze direction of that agent. Participants observed a video-clip of a face rotating 60⁰ towards them starting from the left or right profile view. The gaze direction of the face was either congruent with, ahead of, or lagging behind the angle of …

Recognition of Emotions From Facial Expression and Situational Cues in Children with Autism
… with computer-generated direct and averted eye-gaze at 100% and 50% emotion strength. Of particular interest were whether eye-gaze direction and emotion strength affect children's interpretation of facially expressed emotions and whether these factors influence perception in a different way for …

Novel eye feature extraction and tracking for non-visual eye-movement applications
… corners) that are combined to calculate the 2D gaze direction and to classify each eye-movement to one of eight classes from the EAC model. The applicability of the eyetracker is demonstrated through a pilot study that serves as a real-world application case study. The performance of the …

Evaluation Toolkit for Adaptable Automatic Gaze Estimation
… involves presenting stimuli and observing the direction and duration of their gaze [5]. Experiments of this type currently require human annotation, or special hardware like infrared eye tracking to annotate video data of the infants’ faces. The MIT Early Childhood Cognition Lab developed the …

Word learning strategies in early childhood : mutual exclusivity across language backgrounds
… (Chapter 4) and between mutual exclusivity, gaze direction and speaker language background (Chapter 5) on referent selection. Challenging prior assumptions, these experiments provided compelling evidence that bilingual and monolingual children use mutual exclusivity to the same extent and do …

Learning through looking and listening
… information about each other. In particular, gaze and speech are rich sources of information about other peoples' thoughts. This thesis investigates these modes. In the first part of the thesis, we describe our work on predicting human gaze. We introduce a series of methods to follow gaze for …

Improving coarticulation performance of 3D avatar and gaze estimation using RGB webcam
… patient portal messages using 3D avatar and gaze estimation using a single RGB camera. The first application aims to help patients, especially those with poor health and low medical literacy, to understand messages delivered by patient portal systems by enhancing the messages with a 3D …

Sociable machines : expressive social exchange between humans and robots
… and delivers social signals to people through gaze direction, facial expression, body posture, and vocalizations. We present the implementation of Kismet's social competencies and evaluate each with respect to: 1) the ability of naive subjects to read and interpret the robot's social cues, 2) …

Studying Eye Gaze of Children with Autism Spectrum Disorders in Interaction with a Social Robot
… control, emotional facial expressions, and eye gaze attention. In this thesis, we focus on studying the feasibility and effectiveness of using a social robot, called NAO, at modeling and improving the social responses and behaviors of children with autism. In our investigation, we designed and …

Evaluating the Feasibility of Integrating Webcam-Based Eye Tracking into Hazard Perception Assessments
… into the integration of webcam-based gaze estimation within a hazard perception testing framework. A prototype system was developed using MediaPipe to estimate gaze direction during video-based hazard perception tasks, enabling the capture of low-resolution attentional signals using …

Inter-Brain Synchronization in Collaborative Virtual Reality
… finger task to investigate the influence of gaze direction on inter-brain synchrony and to examine its connection with the perceived social presence in VEs. Experiment 4 used a collaboration task (finding a box with the right letter-number combination) and different avatars to study the …

HeadLock : wide-range head pose estimation for low resolution video
… recordings. Head pose, as an approximation of gaze direction, is a key indicator of human behavior and interaction. Extracting head pose information from video recordings is a labor intensive endeavor that severely limits the feasibility of using large video corpora to perform tasks that …

Exploring the Design, Use and Impact of Companion Pet Robots and Automata for Older Adults and People with Dementia
… simulation, lap-sized frame, interactivity and gaze direction and costing <£250. An effective infection control procedure was developed proven for bacterial infection of robot pets (with varying shell types), in care home settings. Ethical concerns on robot use, as reported in literature, were …

Spontaneous Facial Behavior Computing in Human Machine Interaction with Applications in Autism Treatment
… analyze and compute facial behaviors (i.e. eye gaze and head orientation) of individuals in real-world HRI system. Due to the fact that children with Autism Spectrum Disorder (ASD) show interest toward technology, we designed and conducted a set of robot-based games to study and foster the …

Ultra-Fast and Multi-Dimensional Face Processing in a New Face Area
… before, as well as facial expressions and gaze in MD. We found that MD populations form a face-selective cluster with a degree of selectivity comparable to that of areas in the core face-processing network. MD encodes facial identity, expression, and head orientation robustly and …
