Abstract

A wearable display and an adjusting method thereof are provided. The adjusting method comprises the following steps. A background image is provided. A central mark is displayed and overlapped with the background image. A first sight line passes through the central mark. A blind spot mark is displayed and overlapped with the background image. A second sight line passes through the blind spot mark. An included angle between the first sight line and the second sight line is substantially 14 to 16 degrees.

Claims

1. An adjusting method of a wearable display, for adjusting an orientation of the wearable display, the adjusting method comprising:

providing a background image,

displaying a central mark on a display unit of the wearable display, wherein the central mark is overlapped with the background image, and a first sight line passes through the central mark; and

displaying a blind spot mark on the display unit, wherein the blind spot mark is overlapped with the background image, a second sight line passed through the blind spot mark, and an included angle between the first sight line and the second sight line is 14 to 16 degrees.

2. The adjusting method of the wearable display according to claim 1, wherein the included angle is 15 degrees.

3. The adjusting method of the wearable display according to claim 1, wherein the central mark and the blind spot mark are displayed in front of the same eye.

4. The adjusting method of the wearable display according to claim 1, further comprising:

automatically rotating the wearable display.

5. The adjusting method of the wearable display according to claim 4, further comprising:

stopping the rotation of the wearable display according to a controlling signal.

6. The adjusting method of the wearable display according to claim 1, further comprising:

automatically rotating the blind spot mark.

7. The adjusting method of the wearable display according to claim 6, further comprising:

stopping the rotation of the blind spot mark according to a controlling signal.

8. The adjusting method of the wearable display according to claim 6, wherein the central mark is cross shaped and the blind spot mark is circular shaped.

9. The adjusting method of the wearable display according to claim 1, wherein the blind spot mark is composed of a plurality of patterns.

10. The adjusting method of the wearable display according to claim 1, wherein the central mark is composed of a plurality of patterns.

11. A wearable display, comprising:

a display unit; and

a processing unit, used for controlling the display unit to show a central mark and a blind spot mark overlapped with a background, wherein a first sight line passes through the central mark, a second sight line passes through the blind spot mark, and an included angle between the first sight line and the second sight line is 14 to 16 degrees.

12. The wearable display according to claim 11, wherein the included angle is 15 degrees.

13. The wearable display according to claim 11, wherein the central mark and the blind spot mark are displayed in front of the same eye.

14. The wearable display according to claim 11, further comprising:

a rotating unit, used for automatically rotating the wearable display.

15. The wearable display according to claim 14, wherein the rotating unit stops the rotation of the wearable display according to a controlling signal.

16. The wearable display according to claim 11, wherein the processing unit further automatically rotates the blind spot mark.

17. The wearable display according to claim 16, wherein the processing unit further stops the rotation of the blind spot mark according a controlling signal.

18. The wearable display according to claim 11, wherein the central mark is cross shaped and the blind spot mark is circular shaped.

19. The wearable display according to claim 11, wherein the blind spot mark is composed of a plurality of patterns.

20. The wearable display according to claim 11, wherein the central mark is composed of a plurality of patterns.

21. An adjusting method of a wearable display, for adjusting an orientation of the wearable display, the adjusting method comprising:

providing a background image;

displaying a central mark on a display unit of the wearable display, wherein the central mark is overlapped with the background image; and

displaying a blind spot mark on the display unit, wherein the blind spot mark is overlapped with the background image, a distance between the central mark and the blind spot mark measured on the display unit is 3 to 5 centimeters.

22. The adjusting method of the wearable display according to claim 21, wherein the distance between the central mark and the blind spot mark measured on the display unit is 4 centimeters.

23. A wearable display, comprising:

a display unit; and

a processing unit, used for controlling the display unit to show a central mark and a blind spot mark overlapped with a background image, wherein a distance between the central mark and the blind spot mark measured on the display unit is 3 to 5 centimeters.
