Abstract

A display method is disclosed. The display method includes the following steps. Capture a facial feature of a user to obtain an image. Process the image to obtain a viewing angle of the user. Scroll page content displayed by a display element according to the viewing angle of the user. A display device is also disclosed.

Claims

1. A display method comprising:

(a) capturing a facial feature of a user to obtain an image;

(b) processing the image to obtain a viewing angle of the user; and

(c) scrolling page content displayed by a display element according to the viewing angle of the user, wherein the step (c) comprises;

(l) obtaining a line number in a page-down region of the page content, wherein the viewing angle of the user is less than a non-scrolling range when sight of the user falls on the page-down region;

(m) counting a read-line number read by the user when the viewing angle of the user is less than the non-scrolling range;

(n) determining if the read-line number is more than the line number; and

(o) making the page content page-down when the read-line number is more than the line number.

2. The display method of claim 1, wherein the step (c) further comprises:

(d) determining if the viewing angle of the user stays in a page-up range for more than a page-up time; and

(e) making the page content page-up when the viewing angle of the user stays in the page-up range for more than the page-up time.

3. The display method of claim 1, wherein the step (c) further comprises:

(f) determining if the viewing angle of the user stays in a page-down range for more than a page-down time; and

(g) making the page content page-down when the viewing angle of the user stays in the page-down range for more than the page-down time.

4. The display method of claim 1, wherein the step (c) further comprises:

(h) determining if the viewing angle of the user is more than a non-scrolling range; and

(i) scrolling forwards the page content when the viewing angle of the user is more than the non-scrolling range.

5. The display method of claim 1, wherein the step (c) further comprises:

(j) determining if the viewing angle of the user is less than a non-scrolling range; and

(k) scrolling backwards the page content when the viewing angle of the user is less than the non-scrolling range.

6. A display device comprising:

a display element for displaying page content;

a camera for capturing a facial feature of a user to obtain an image;

an image-processing element for processing the image to obtain a viewing angle of the user; and

a page-content-scrolling element for scrolling the page content according to the viewing angle of the user, wherein the page-content-scrolling element comprises;

a line-obtaining element for obtaining a line number in a page-down region of the page content, wherein the viewing angle of the user is less than a non-scrolling range when sight of the user falls on the page-down region;

a line-counting element for counting a read-line number read by the user when the viewing angle of the user is less than the non-scrolling range;

a comparing element for comparing the line number and the read-line number; and

a page-down element for making the page content page-down when the read-line number is more than the line number.

7. The display device of claim 6, wherein the page-content-scrolling element further comprises:

an angle-determination element for determining if the viewing angle of the user stays in a page-up range for more than a page-up time; and

a page-up element for making the page content page-up when the viewing angle of the user stays in the page-up range for more than the page-up time.

8. The display device of claim 6, wherein the page-content-scrolling element further comprises:

an angle-determination element for determining if the viewing angle of the user stays in a page-down range for more than a page-down time; and

a page-down element for making the page content page-down when the viewing angle of the user stays in the page-down range for more than the page-down time.

9. The display device of claim 6, wherein the page-content-scrolling element further comprises:

an angle-determination element for determining if the viewing angle of the user is more than a non-scrolling range; and

a scrolling-forwards element for scrolling the page content forwards when the viewing angle of the user is more than the non-scrolling range.

10. The display device of claim 6, wherein the page-content-scrolling element further comprises:

an angle-determination element for determining if the viewing angle of the user is less than a non-scrolling range; and

a scrolling-backwards element for scrolling the page content backwards when the viewing angle of the user is less than the non-scrolling range.
