Summary:Examples are disclosed herein that relate to eye tracking based on two-dimensional image data. One example provides, on a computing device, a method of tracking an eye. The method includes receiving image data from an image sensor, detecting a face of the user in the image data, locating the eye in a region of the face in the image data to obtain an eye image, normalizing one or more of a scale and an illumination of the eye image, fitting an ellipse to an iris of the eye in the eye image, and outputting a determination of an eye gaze direction based upon the ellipse fitted. 在此公开了涉及基于二维图像数据的眼睛跟踪的各示例。个示例提供了在计算设备上的种跟踪眼睛的方法。所述方法包括从图像传感器接收图像数据、检测图像数据中的用户的脸部、定位在图像数据中的脸部区域中的眼睛以获得眼睛图像，规范化眼睛图像的比例和照明中的个或多个、将个椭圆形拟合于眼睛图像中的眼睛的虹膜、并基于所拟合的椭圆形输出眼睛注视方向的确定。
