1. A head-mounted display device, comprising:
a sensor, configured to capture an eye image of an eye of a user; and
a controller, coupled to the sensor and configured to:
analyze the eye image to generate an analysis result, wherein the analysis result indicates that whether the eye in the eye image is clear or not; and
in response to the analysis result indicating that the eye in the eye image is not clear, output an issue detected signal,
wherein in response to the issue detected signal being outputted, the controller is configured to:
perform an eye tracking operation based on a first tracking algorithm on the eye image to generate a first tracking result;
perform the eye tracking operation based on a second tracking algorithm on the eye image to generate a second tracking result;
compare the first tracking result with the second tracking result to determine a better tracking result; and
output the better tracking result as a result of the eye tracking operation.
