The locations of the eye pupil centers are used in a wide range of computer vision applications. Although there are successful commercial eye gaze tracking systems, their practical employment is limited due to required specialized hardware and extra restrictions on the users. On the other hand, the precision and robustness of the off the shelf camera based systems are not at desirable levels. W...

In this paper, we present a novel approach, called the “one-circle” algorithm, for measuring the eye gaze using a monocular image that zooms in on only one eye of a person. Observing that the iris contour is a circle, we estimate the normal direction of this iris circle, considered as the eye gaze, from its elliptical image. From basic projective geometry, an ellipse can be backprojected into s...

Eye gaze tracking (EGT) is a common problem with many applications in various fields. While recent methods have achieved improvements in accuracy and usability, current techniques still share several limitations. A major issue is the need for external calibration between the gaze camera system and the scene, which commonly restricts to static planar surfaces and leads to parallax errors. To ove...

Morphable face models are a powerful tool in computer vision and graphics, but have previously failed to model the eye accurately due to complexities in its material and motion. We present a new multi-part model of the eye that includes a morphable model of the facial eye region, as well as an anatomy-based eyeball model. It is the first morphable model that accurately captures eye region shape...

Close behavioural coupling of visual orientation may provide a range of adaptive benefits to social species. In order to investigate the natural properties of gaze-following between pedestrians, we displayed an attractive stimulus in a frequently trafficked corridor within which a hidden camera was placed to detect directed gaze from passers-by. The presence of visual cues towards the stimulus ...

Analysis of human spatial cognition when navigating within physical or virtual environments can be bolstered by collecting eye movements with the help of an eye tracker. In physical reality, a head-mounted tracker can be worn during navigation with recorded gaze data often mapped to the screen coordinates of a forward-facing camera. In virtual reality, gaze data can be recorded with a so-called...

In many practical situations, a desirable user interface to a computer system should have a model of where a person is looking at and what he/she is paying attention to. This is particularly important if a system is providing multi-modal communication cues, speech, gesture, lipreading , etc., 2, 3, 8] and the system must identify, whether the cues are aimed at it, or at someone else in the room...

The ability to perform quantitative and automated neurological assessment could enhance diagnosis treatment in the pre-hospital setting, such as during telemedicine or emergency medical services (EMS) encounters. Such a tool be developed by adapting clinically significant information symmetry of eye movement conjugate movement. Here we describe digital camera-based tracking method “NeuroGaze” c...

In first encounters people quickly form impressions of each other’s personality and interpersonal attitude. We conducted a study to investigate how this transfers to first encounters between humans and virtual agents. In the study, subjects’ avatars approached greeting agents in a virtual museum rendered in both first and third person perspective. Each agent exclusively exhibited nonverbal imme...
