Extending touch with eye gaze input
… many instances of direct interaction, both the eyes and hands play an integral role in accomplishing the user's interaction goals. The eyes visually select objects, and the hands physically manipulate them. In principle this process includes a two-step selection of the same object: users rst …

Mobile robot teleoperation through eye-gaze (telegaze)
… images displayed on an interaction screen. The eyes of the operator therefore, are fully engaged in monitoring and the hands in controlling. Since the eyes of the operator are engaged in monitoring anyway, inputs from their gaze can be used to aid in controlling. This frees the hands of the …

Embedded Eye-Gaze Tracking On Mobile Devices
The eyes are one of the most expressive non-verbal tools a person has and they are able to communicate a great deal to the outside world about the intentions of that person. Being able to decipher these communications through robust and non-intrusive gaze tracking techniques is increasingly …

Understanding the effectiveness of visual cues through analyzing eye gaze data
Historically eye movement analysis has been viewed to provide a window onto the audience’s mind, as stated in the eye mind hypothesis and it has been found that eye gaze pattern and mental process is closely related. To investigate the effectiveness of visual cues accompanied by audio narration, we …

Eye-Gaze Analyis of Facial Emotion Expression in Adolescents with ASD
… in ASD. The aim of this study was to assess eye gaze patterns during scripted and spontaneous emotion expression tasks, and to assess quality of emotional expression in relation to gaze patterns. Youth with ASD fixated less to the eye region of stimuli showing surprise (F(1,19.88) = 4.76, p = …

Enhancing Security and Privacy in Head-Mounted Augmented Reality Systems Using Eye Gaze
… array of sensors such as cameras, depth sensors, eye gaze trackers, microphones, and inertial sensors. The ability of these devices to collect this information presents both challenges and opportunities to improve existing security and privacy techniques in this domain. Specifically, eye gaze …

The Effects of Eye Gaze Based Control on Operator Performance in Monitoring Multiple Displays
… investigated the utility and efficacy of using eye tracking technology as a method for selecting control of a camera within a multiple display configuration. A task analysis with a Keystroke-Level-Model (KLM) was conducted to acquire an estimated time for switching between cameras. KLM estimates …

Visual orienting to eye gaze in individuals with high and low levels of autistic traits
… spectrum disorders have a tendency to avoid eye contact and show a lack of voluntary and spontaneous gaze following behaviour. Research using gaze cueing paradigms has suggested that although individuals with autism can and do reflexively orient to gaze cues, this is done using atypical …

Studying Eye Gaze of Children with Autism Spectrum Disorders in Interaction with a Social Robot
… motor 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 …

Mechanisms of Empathic Behavior in Children with Callous-Unemotional Traits: Eye Gaze and Emotion Recognition
… related to deficits in visual attention to the eye region of others. Notably, recognition of others' distress necessarily precedes sympathy, and sympathy is a key predictor in prosocial outcomes. Thus, visual attention and emotion recognition may mediate the relationship between CU traits and …

Eye-Gaze Pattern Analysis as a Key to Understanding Co-occurring Social Anxiety within Autism Spectrum Disorder
… in this population. Direct examination of overt eye gaze patterns may help determine if the attentional biases often reported in people with SAD also operate in those with ASD and co-occurring social anxiety. This study sought to assess the influence of social anxiety on gaze patterns in adults …

Eye Gaze Does Not Attenuate Cognitive Load on 14-Month-Olds' Word-Object Associative Learning for Minimal Pairs
… (i.e., no face versus face with shifting gaze) to habituate infants with objects and minimal pair labels. Additionally, infants participated in a joint attention task and parents completed questionnaires related to family demographics and infant health and development, to compare to switch …

Cognitive Vulnerability to Depression: A Longitudinal Study using Eye-gaze Tracking to Study Attentional Biases in Never Depressed, Non-Relapsed, and Relapsed Individuals
Cognitive models of depression propose that attentional biases are an important cognitive vulnerability in those with a history of depression (e.g., Gotlib & Joormann, 2010; Yiend, 2010; Beck & Haigh, 2014). This study prospectively examined attentional biases in never and previously depressed …

The Influence of Text on Coherence of Story Retells, Reading Comprehension, Vocabulary Acquisition, and Eye Gaze: A Computer-Based Story Telling Task with Eye Tracking
… access to the text would affect children’s eye gaze patterns while viewing the story, which had been found during the pilot study. It was hypothesized that the group who had access to their native English text would perform better in measures of comprehension and vocabulary knowledge and …

Design and Development of a Chatbot as an Alternative Web-browser for those with Severe Motor Impairments
… evaluating two complementary solutions: (1) an eye gaze-controlled chatbot for hands-free, conversational access to online information, and (2) a synthetic data generation approach to improve voice-based chatbot systems’ ability to interpret atypical speech. First, an empirical study involving …

Random center- surround approaches for modeling visual saliency
… to detect salient regions and simulate human eye-gaze on images and videos. A majority of the existing approaches are highly parametric in nature. They are specialized to predict either eye-gaze or detect salient regions, but not both simultaneously. Like other computer vision approaches, the …

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 …
