Opis:
Eye-gaze tracking is an aspect of human-computer interaction still growing in popularity,. Tracking human gaze point can help control user interfaces and may help evaluate graphical user interfaces. At the same time professional eye-trackers are very expensive and thus unavailable for most of user interface researchers and small companies. The paper presents very effective, low cost, computer vision based, interactive eye-gaze tracking method. On contrary to other authors results the method achieves very high precision (about 1.5 deg horizontally and 2.5 deg vertically) at 20 fps performance, exploiting a simple HD web camera with reasonable environment restrictions. The paper describes the algorithms used in the eye-gaze tracking method and results of experimental tests, both static absolute point of interest estimation, and dynamic functional gaze controlled cursor steering.

Opis:
Simultaneous perception of audio and visual stimuli often causes concealment or misrepresentation of information actually contained in these stimuli. Such effects are called the "image proximity effect" or the "ventriloquism effect" in the literature. Until recently, most research carried out to understand their nature was based on subjective assessments. The authors of this paper propose a methodology based on both subjective and objectively retrieved data. In this methodology, objective data reflect the screen areas that attract most attention. The data were collected and processed by an eye-gaze tracking system. To support the proposed methodology, two series of experiments were conducted – one with a commercial eye-gaze tracking system Tobii T60, and another with the Cyber-Eye system developed at the Multimedia Systems Department of the Gdańsk University of Technology. In most cases, the visual-auditory stimuli were presented using a 3D video. It was found that the eye-gaze tracking system did objectivize the results of experiments. Moreover, the tests revealed a strong correlation between the localization of a visual stimulus on which a participant’s gaze focused and the value of the "image proximity effect". It was also proved that gaze tracking may be useful in experiments which aim at evaluation of the proximity effect when presented visual stimuli are stereoscopic.

Opis:
Two common channels through which humans communicate are speech and gaze. Eye gaze is an important mode of communication: it allows people tobetter understand each others’ intentions, desires, interests, and so on. The goal of this research is to develop a framework for gaze triggered events that can be executed on a robot and mobile devices and allows to perform experiments. We experimentally evaluate the framework and techniques for extracting gaze direction based on a robot-mounted camera or a mobile-device camera that are implemented in the framework. We investigate the impact of light on the accuracy of gaze estimation, and also how the overall accuracy depends on user eye and head movements. Our research shows that light intensity is important, and the placement of a light source is crucial. All the robot-mounted gaze detection modules we tested were found to be similar with regard to their accuracy. The framework we developed was tested in a human-robot interaction experiment involving a job-interview scenario. The flexible structure of this scenario allowed us to test different components of the framework in varied real-world scenarios, which was very useful for progressing towards our long-term research goal of designing intuitive gaze-based interfaces for human robot communication.

Opis:
Eye-tracking is a technology based on tracking the movement of eyeballs. The results of the study allow a detailed analysis of the path of sight, and provide answers to the questions: what are we looking at, what we focus on and what we ignore despite that the objects are located in our field of view. The eye movement tracking is not a new technology, but it is constantly improved and is gaining importance in many fields of science and consumer market research. Contemporary culture, oriented to image absorption, is a perfect surface for non-standard eye-tracking research.
Eye-tracking to technologia, której działanie polega na śledzeniu ruchu gałek ocznych. Wyniki badania pozwalają na szczegółową analizę ścieżki wzroku, udzielają odpowiedzi na pytania, na co patrzymy, na czym skupiamy największą uwagę, a co ignorujemy i czego nie dostrzegamy, pomimo tego, że znajduje się w polu widzenia. Śledzenie ruchu gałek ocznych nie jest technologią nową, jednak stale udoskonalane, zyskuje coraz większe znaczenie w życiu codziennym, wielu dziedzinach nauki i w badaniach rynku konsumenckiego. Współczesna kultura, zorientowana na absorbcję obrazów, jest szczególnie doskonałą płaszczyzną, na której badania eye-trackingowe znajdują wiele często niestandardowych zastosowań.
