In the viewing direction detecting step S1, the direction of the eyeball 51 or the pupil 52 is detected, so that the viewing direction and the viewing area of the eye 50 can be determined according to the direction of the eyeball 51 or the pupil 52.

In the step of controlling the display operation S3, after detecting the viewing direction of the eye 50, the processor 11 controls the display area 130 corresponding to the viewing direction of the eye 50 to operate, so that the operation of the display module 13 can be controlled by the viewing direction of the eye 50, so as to operate the corresponding display area 130 when the enhancement is needed.

Referring to fig. 2 and fig. 6, the display module 13 has a plurality of display regions 130, and the display regions 130 respectively correspond to different viewing directions of the eyes 50; a first direction as viewed by the display area 130a corresponding to the eye 50; the display area 130b corresponds to the second direction of viewing by the eye 50; display area 130c corresponds to the eye 50 viewing a third direction, and so on.

Referring to fig. 6 and 7, when the eye 50 views a first direction, such as looking forward, one display region 130a of the display module 13 is active, and the other display regions, such as the display region 130b and the display region 130c, are inactive, so that the eye 50 sees an image in the first direction, and the eye 50 sees the first image 61 displayed in the first direction.
