Efficient Eye Typing with 9-direction Gaze Estimation

, 2017
Vision based text entry systems aim to help disabled people achieve text communication using eye movement. Most previous methods have employed an existing eye tracker to predict gaze direction and design an input method based upon that.

A Differential Approach for Gaze Estimation

, 2019
Non-invasive gaze estimation methods usually regress gaze directions directly from a single face or eye image. However, due to important variabilities in eye shapes and inner eye structures amongst individuals, universal models obtain limited accuracies ...

A framework for realistic 3D tele-immersion [PDF]

, 2013
Meeting, socializing and conversing online with a group of people using teleconferencing systems is still quite differ- ent from the experience of meeting face to face. We are abruptly aware that we are online and that the people we are engaging with are

Improving Few-Shot User-Specific Gaze Adaptation via Gaze Redirection Synthesis

, 2019
As an indicator of human attention gaze is a subtle behavioral cue which can be exploited in many applications. However, inferring 3D gaze direction is challenging even for deep neural networks given the lack of large amount of data (groundtruthing gaze ...

AVEID: Automatic Video System for Measuring Engagement In Dementia [PDF]

, 2017
Engagement in dementia is typically measured using behavior observational scales (BOS) that are tedious and involve intensive manual labor to annotate, and are therefore not easily scalable.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Optimizing Within-Domain Gaze Estimation: Insights From a Novel Appearance-Based 2D Model

IEEE Access
Appearance-based gaze estimation has emerged as a promising alternative to traditional model-based methods, effectively addressing their limitations in terms of flexibility, cost, and adaptability to unconstrained environments. In this study, the Digital

Evaluating Engagement in Digital Narratives from Facial Data [PDF]

, 2017
Engagement researchers indicate that the engagement level of people in a narrative has an influence on people's subsequent story-related attitudes and beliefs, which helps psychologists understand people's social behaviours and personal experience.

A Head Pose-free Approach for Appearance-based Gaze Estimation [PDF]

Procedings of the British Machine Vision Conference 2011, 2011
T o infer human gaze from eye appearance, various methods have been proposed. However, most of them assume a fixed head pose because allowing free head motion adds 6 degrees of freedom to the problem and requires a prohibitively large number of training samples.

Schooling Trajectories and the Development of Brain Dynamics: A Comparative Study of Montessori and Traditional Education

Advanced Science, EarlyView.
We investigate whether Montessori and traditional schooling systems shape the developmental trajectory of large‐scale brain dynamics in different ways. We quantify the arrow of time (“non‐reversibility”) in neural activity during resting state and movie‐watching, revealing distinct maturational patterns.
