This paper describes a method to estimate the gaze direction using cornea images captured by a single camera. The purpose is to develop wearable devices capable of obtaining natural user responses, such as interests and behaviors, from eye movements and scene images reflected on the cornea. From an image of the eye, an ellipse is fitted on the colored iris area. A 3D eye model is reconstructed from the ellipse and rotated to simulate projections of the iris area for different eye poses.

Gaze tracking using corneal images captured by a single high-sensitivity camera
TLDR
A method to estimate gaze direction using images of the eye captured by a single high-sensitivity camera, which relies on a model approach to evaluate the gaze direction and does not require a frontal camera to capture scene information, making it more socially acceptable if embedded in a glassesshaped device.

TLDR
A comparison was made between the techniques used to detect the human eye gaze and the results show that the use Nonintrusive methods based on video easier and not expensive when Compared to other techniques especially used the single camera in the modern mobile devices.
A Glimpse of the Future at IBC 2016 3 Selected Content from IBC 2016 WiB – a new system concept for digital terrestrial television ( DTT ) 4
A new system concept for DTT, called “WiB”, is presented, where potentially all frequencies within the Ultra High Frequency (UHF) band are used on all transmitter (TX) sites (i.e. reuse-1). The
Adaptive Bingham Distribution Based Filter for SE (3) Estimation
TLDR
This work equips the Bingham distribution based filter with adaptive filtering ability, which realizes completely autonomous tuning without human interaction, which is significantly laborsaving compared to the state-of-the-art methods as well as capable of maintaining high accuracy.
STARE: Realtime, Wearable, Simultaneous Gaze Tracking and Object Recognition from Eye Images
TLDR
A model-based approach to estimate the gaze direction using red-green-blue (RGB) eye images; a method to recognize objects in the scene reflected on the cornea in real time; and a 3D-printable prototype of a wearable gaze-tracking device are described.
Gaze Tracking and Object Recognition from Eye Images
TLDR
A method to identify the focused object in eye images captured from a single camera in order to enable intuitive eye-based interactions using wearable devices and relies on a 3D eye model reconstruction to evaluate the gaze direction from the eye images.

Estimation of a focused object using a corneal surface image for eye-based interaction
TLDR
This work proposes a novel method for estimating the object that a user is focused upon, where an eye camera captures the reflection on the corneal surface and uses inverse ray tracing and a scale-invariant feature transform to estimate the object where the point-of-regard is located.
Non-calibrated and real-time human view estimation using a mobile corneal imaging camera
TLDR
A mobile human view estimation system using a corneal imaging technique that does not require per-session calibrations and a frontal view (scene) camera, making it suitable for wearable glass systems because it is easier to use and more socially acceptable due to the lack of a frontal scene camera.
Unwrapping the eye for visible-spectrum gaze tracking on wearable devices
TLDR
This paper calibrates a three-dimensional eye model based on the location of the corners of the eye and proposes a robust circle-fitting procedure that finds the iris contour by searching for a circle on the eye surface.
Estimating point-of-regard using corneal surface image
TLDR
A method for conserving the relationship between the scene and eye camera during the execution of an eye-tracking program is proposed, using the texture information of the corneal surface image to estimate the point-of-regard.

Direct Least Square Fitting of Ellipses
TLDR
This work presents a new efficient method for fitting ellipses to scattered data by minimizing the algebraic distance subject to the constraint 4ac-b/sup 2/=1, which incorporates the ellipticity constraint into the normalization factor.
