A method of tracking a gaze of an eye includes tracking the gaze of the eye in a first tracking mode. Glint data of at least one glint of the eye is obtained during at least a portion of tracking the gaze of the eye in the first tracking mode. The glint data is in a time domain and includes a time s...

Abstract | A method of tracking a gaze of an eye includes tracking the gaze of the eye in a first tracking mode. Glint data of at least one glint of the eye is obtained during at least a portion of tracking the gaze of the eye in the first tracking mode. The glint data is in a time domain and includes a time series of a spatial descriptor associated with the at least one glint. The glint data is transformed into a frequency domain to generate a glint frequency spectrum. A stability of the at least one glint is determined based on the glint frequency spectrum. If the at least one glint is determined to be unstable, tracking of the gaze of the eye is switched from the first tracking mode to a second tracking mode that is different from the first tracking mode. |
