Abstract: A method for eye tracking in a head-mountable device (HMD) includes determining at least one object within a three-dimensional (3D) extended reality (XR) environment as an eye tracking calibration point and determining a 3D location of the eye tracking calibration point within the XR environment. The method also includes detecting a gaze point of a user of the HMD and comparing the detected gaze point to an area of the XR environment that includes the 3D location of the eye tracking calibration point. The method further includes, in response to determining that the user is looking at the eye tracking calibration point based on the detected gaze point being within the area, calibrating, using a processor, the HMD to correct a difference between the eye tracking calibration point and the detected gaze point. In addition, the method includes, in response to determining that the user is not looking at the eye tracking calibration point based on the detected gaze point being outside of the area, maintaining an existing calibration of the HMD.

Abstract: A method, an electronic device and a non-transitory computer readable medium for are provided. The method includes capturing a first eye and a second eye. The method also includes identifying a first position of the first eye and a second position the second eye. Additionally, the method includes staggering the capture of the first eye and the second eye, wherein the first eye is captured prior to capturing the second eye. The method also includes identifying the first gaze direction with respect to a display. The method further includes mapping the second gaze direction of the second eye based on the identified first gaze direction, prior to capturing the second eye.
