In a calibration process for an eye-tracking application, a calibration mark is displayed on an instrument, and the user is instructed to keep the gaze focused on the calibration mark. Next, a dynamic image is displayed on the instrument, and the user is instructed to move his head or the instrument as indicated by the dynamic image while keeping the gaze focused on the calibration mark. The ocular information of the user is recorded during the head movement or the instrument movement for calibrating the eye-tracking application.

Method of calibrating eye-tracking application and related optical system

An eye-tracking module includes a power management module, a sensing module and a processor. The power management module is configured to supply power according to a power control signal for operating the eye-tracking module in a corresponding mode, and provide a power status signal associated its power supplying status. The sensing module includes at least one image sensor configured to capture an eye image of a user at a sampling rate. The processor is configured to acquire eye characteristics of the user, the eye-movement information of the user, or vision information including user gaze coordinates according to the eye image. The processor is also configured to adjust the sampling rate, adjust its output frequency and/or switch the operational mode of the eye-tracking module according to the power status signal.
