A neural network based real-time gaze tracker
نویسندگان
چکیده
A real-time gaze-tracking system that estimates the user's eye gaze and computes the window of focused view on a computer monitor has been developed. This arti®cial neural network based system can be trained and customized for an individual. Unlike existing systems in which skin color features and/or other mountable equipment are needed, this system is based on a simple non-intrusive camera mounted on the monitor. Gaze point is accurately estimated within a 1 in. on a 19-in. monitor with a CCD camera having a 640 480 image resolution. The system performance is independent of user's forward and backward as well as upward and downward movements. The gaze-tracking system implementation and the factors affecting its performance are discussed and analyzed in detail. The features and implementation methods that make this system real-time are also explained. # 2002 Elsevier Science Ltd. All rights reserved.

Tracking Eyes and Monitoring Eye Gaze
In this paper, we present a non-intrusive eye tracker which can detect and track a user's eyes in real time as soon as the face appears in the view of the camera without special lighting or any marks on the user's face. We also discuss the problem of gaze monitoring. We employ neural networks to estimate a user's eye gaze using the images of user's both eyes as input to the neural networks. We ...
متن کاملTowards Tracking Interaction Between People
During face-to-face communication people make use of both verbal and visual behaviors. In this paper we address the problem of tracking visual cues between people. We propose a hybrid approach to tracking who is looking at whom during a discussion or meeting situation. A neural network and a model based gaze tracker are combined to track gaze directions of participants in a meeting. The neural ...
متن کاملA Time Delay Neural Network model for simulating eye gaze data
Human eye movement modelling is a new, challenging, and promising research topic in computer vision. Human eye movement modelling aims at simulating the scan path in which a human being views an image, scene, or video. The successful modelling of human eye movements potentially benefits a wide range of applications such as image retrieval, image annotation, medical image diagnosis, and human vi...
متن کاملA Novel Approach to Real-time Non-intrusive Gaze Finding
We investigate a holistic approach to real-time gaze tracking by means of a well-defined neural network modelling strategy combined with robust image processing algorithms. Based on captured greyscale eye images, the system effectively learns the gaze direction of a human user by modelling implicitly corresponding eye appearance – the relative positions of the pupil, cornea, and light reflectio...
متن کاملA Novel Neural Eye Gaze Tracker
A gaze tracking system, based on a novel neural approach, is proposed. The work is part of a wider research project concerning the development of human computer interfaces (HCI) addressed to disabled people, that could overcome the drawbacks of most of the existing methods for gaze tracking that require either intrusive devices or expensive equipment. This work, instead, aims at developing a lo...
