Simplifying the Cross-ratios Method of Point-of-gaze Estimation
Point-of-gaze estimation systems estimate the point within the visual field that is imaged on the highest acuity region of the retina known as the fovea. A new method has been introduced that estimates point-of-gaze by exploiting the invariance property of cross-ratios in projective transformations [1]. The projective transformation is formed by two perspective projections. The first projection...
متن کاملImplementation of EOG-based Gaze Estimation in HMD with Head-tracker
Head-mounted displays (HMDs) are effective devices for creating immersive virtual environments. Intuitive movement field-of view (FOV) is possible in virtual reality (VR) space with a HMD equipped with a head-tracker. However, gaze targets are not accurately detectable by the measurement of head movements alone. An eye-tracker is needed to determine gaze positions; however, such trackers curren...
متن کاملAn Incremental Learning Method for Unconstrained Gaze Estimation
This paper presents an online learning algorithm for appearancebased gaze estimation that allows free head movement in a casual desktop environment. Our method avoids the lengthy calibration stage using an incremental learning approach. Our system keeps running as a background process on the desktop PC and continuously updates the estimation parameters by taking user’s operations on the PC moni...
متن کاملRobust Eye Gaze Estimation
Eye gaze detection under challenging lighting conditions is a non-trivial task. Pixel intensity and the shades around the eye region may change depending on the time of day, location, or due to artificial lighting. This paper introduces a lighting-adaptive solution for robust eye gaze detection. First, we propose a binarization and cropping technique to limit our region of interest. Then we dev...
متن کاملGeometry Issues of Gaze Estimation
Video-oculography (VOG) is a non-intrusive method used to estimate gaze. The method is based on a remote camera(s) that provides images of the eyes that are processed by a computer to estimate the point at which the subject is gazing in the area of interest. Normally, infrared (IR) light-emitting diodes (LEDs) are used in the system, as this light is not visible to humans. The objective of the ...
