Gaze Estimation with Graphics
Gaze estimation systems determine where someone is looking. Gaze is used for a wide range of applications including market research, usability studies, and gaze-based interfaces. Traditional equipment uses special hardware. To bring gaze estimation mainstream, researchers are exploring approaches …

Evaluation Toolkit for Adaptable Automatic Gaze Estimation
… 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 project Lookit, which allows …

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 …

TabletGaze: Dataset and Algorithm for Unconstrained Appearance-based Gaze Estimation in Mobile Tablets
In this thesis, we study gaze estimation on tablets. Our key design goal is uncalibrated gaze estimation using the front-facing camera during natural use of tablets, where the posture and method of holding the tablet is not constrained. We collected the first large unconstrained gaze dataset of …

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 …

Visual Objects and Environments: Capture, Extraction, and Representation
… formulated as a probabilistic alpha channel estimation problem. The closed-form solution proposed enables detailed and possibly diffused object boundaries to be found, so that visual objects embedded in digital images can be extracted. We also describe an interactive tool that allows this …

Embedded Eye-Gaze Tracking On Mobile Devices
… communications through robust and non-intrusive gaze tracking techniques is increasingly important as we look toward improving Human-Computer Interaction (HCI). Traditionally, devices which are able to determine a user's gaze are large, expensive and often restrictive. This work investigates the …

Exploration of smooth pursuit eye movements for gaze calibration in games
… new ways of interaction for gameplay. However, gaze has been found challenging to use in dynamic interfaces involving motion. Moving targets are hard to select with state of the art gaze input methods and gaze estimation requires calibration in order to be accurate when offering a successful …

3D face processing for animation and biometrics
… avatar animation, expression recognition and eye gaze estimation. The algorithms contribute to a complete framework for image and video analysis and synthesis based on 3D face models. From the experiments on the self-collected and public database, we argue that feature based 3D face processing is …

Multimodal Eye-Tracking and Predictive Gaze Modelling for Assistive Human–Computer Interaction in Augmentative and Alternative Communication Systems
… speech recognition (ASR), speech synthesis, and gaze prediction to improve communication efficiency and user autonomy. To resolve the accuracy and latency trade-off, the framework implements a Bi-directional Long Short-Term Memory (LSTM) gaze prediction model. By training on the eye-tracking …

Tracking of Eye Movement Features for Individualized Assessment of Neurocognitive State Using Mobile Devices
… we used a deep convolutional neural network for gaze estimation and model-based methods to measure saccade latency and error rates. With the frequent measurements of these features, we then designed an individualized longitudinal model using a Gaussian process that learns individual …

Implicit gaze interaction for information visualization
… rendered visualization objects by collecting the gaze data and calculating the object group’s interest scores across selected visual features. With the interest model, We offer an implicit gaze interaction system that provides subtle interaction supports to improve group-of-interest objects …
