Geometric Eye Gaze Tracking

چکیده
This paper presents a novel eye gaze estimation method based on calculating the gaze vector in a geometric approach. There have been many publications in the topic of eye gaze estimation, but most are related to using dedicated infra red equipment and corneal glints. The presented approach, on the other hand, assumes that only an RGB input image of the user’s face is available. Furthermore, it requires no calibration but only simple one-frame initialization. In comparison to other systems presented in literature, our method has better accuracy. The presented method relies on determining the 3D location of the face and eyes in the initialization frame, tracking these locations in each consecutive frame and using this knowledge to estimating the gaze vector and point where the user is looking. The algorithm runs in real time on mobile devices.

Error Correction in Geometric Method of 3d Gaze Measurement Using Singular Value Decomposition
Utilizing gaze tracker as a tool for human-computer interaction or visual perception understanding has become increasingly popular. Gaze tracking is to compute the position of user’s gaze. Most researcher conduct gaze tracking studies on two-dimensional (2D) plane, such that X and Y position of the user gaze at the monitor is known. However, as the usage of stereoscopic display increases, the i...
متن کاملTowards eye gaze aware analysis and synthesis of audiovisual speech
Eye gaze plays many important roles in audiovisual speech, especially in face-to-face interactions. Eyelid shapes are known to correlate with gaze direction. This correlation is perceived and should be restored when animating 3D talking heads. This paper presents a data-based construction method that models the user’s eyelid geometric deformations caused by gazing and blinking during conversati...
متن کاملEvaluation of Attention Bias in Morphine and Methamphetamine Abusers towards Emotional Scenes during Early Abstinence: An Eye-Tracking Study
Introduction: We hypothesized that inappropriate attention during the period of abstinence in individuals with substance use disorder can result in an inadequate perception of emotion and unsuitable reaction to emotional scenes. The main aim of this research was to evaluate the attentional bias towards emotional images in former substance abusers and compare it to healthy adults. Methods:...
متن کاملA Novel Gaze Tracking Method Based on the Generation of Virtual Calibration Points
Most conventional gaze-tracking systems require that users look at many points during the initial calibration stage, which is inconvenient for them. To avoid this requirement, we propose a new gaze-tracking method with four important characteristics. First, our gaze-tracking system uses a large screen located at a distance from the user, who wears a lightweight device. Second, our system requir...
متن کاملGeometric Generative Gaze Estimation (GE) for Remote RGB-D Cameras
We propose a head pose invariant gaze estimation model for distant RGB-D cameras. It relies on a geometric understanding of the 3D gaze action and generation of eye images. By introducing a semantic segmentation of the eye region within a generative process, the model (i) avoids the critical feature tracking of geometrical approaches requiring high resolution images; (ii) decouples the person d...
