Abstract

According to an illustrative embodiment, a head-mounted display is provided. The head-mounted display includes a casing; and a reference portion provided on the casing for observing an eye of a wearer of the head-mounted display such that a relative position between the casing and the eye of the wearer is adjustable.

Claims

1. A head-mounted display, comprising:

a casing; and

a reference portion provided on the casing for observing an eye of a wearer of the head-mounted display such that a relative position between the casing and the eye of the wearer is adjustable.

2. The head mounted display as recited in claim 1, wherein the reference portion is a window.

3. The head mounted display as recited in claim 2, wherein the eye is visible through the window.

4. The head-mounted display as recited in claim 1, further comprising a mark on the reference portion.

5. The head-mounted display as recited in claim 4, further comprising a left display surface and a right display surface, and wherein the mark indicates a height position of centers for the left display surface and the right display surface.

6. The head-mounted display as recited in claim 5, wherein each of the left display surface and the right display surface is rectangular, and the mark indicates a height position of the intersections of the diagonals for each of the left display surface and the right display surface.

7. The head-mounted display as recited in claim 1, wherein the reference portion is operable to switch between a light-transmitting state and a light-blocking state.

8. The head-mounted display as recited in claim 1, further comprising a movable member movable between a first position and a second position, the first position being a position in which the reference portion is covered, and the second position being a position in which the reference portion is uncovered.

9. The head-mounted display as recited in claim 8, wherein the first position is a position in which an opening portion of the head-mounted display is uncovered such that the wearer can see through the opening portion.

10. The head-mounted display as recited in claim 8, further comprising a mark on the reference portion.

11. The head-mounted display as recited in claim 8, wherein the movable member is manually driven.

12. The head-mounted display as recited in claim 8, wherein the movable member is motor driven.

13. A head-mounted display, comprising:

a casing;

a mounting portion that detachably couples to the casing, the mounting portion including a reference portion for observing an eye of a wearer of the mounting portion; and

a coupler for detachably coupling the casing to the mounting portion,

wherein a relative position between the coupler and the eye of the wearer of the mounting portion is adjustable by observing the eye through the reference portion.

14. The head mounted display as recited in claim 13, wherein the reference portion is a window.

15. The head mounted display as recited in claim 14, wherein the eye is visible through the window.

16. The head-mounted display as recited in claim 13, wherein when the casing is coupled to the mounting portion a side surface of the casing covers the reference portion so as to block light from entering the reference portion.

17. The head-mounted display as recited in claim 13, further comprising a mark on the reference portion.

18. A medical system, comprising:

a head-mounted display, wherein the head-mounted display comprises a casing; and

a reference portion provided on the casing for observing an eye of a wearer of the head-mounted display such that a relative position between the casing and the eye of the wearer is adjustable.

19. The medical system as recited in claim 18, wherein the reference portion is a window.

20. A medical system, comprising:

a head-mounted display, wherein the head mounted display comprises a casing;

a mounting portion that detachably couples to the casing, the mounting portion including a reference portion for observing an eye of a wearer of the mounting portion; and

a coupler for detachably coupling the casing to the mounting portion, wherein a relative position between the coupler and the eye of the wearer of the mounting portion is adjustable by observing the eye through the reference portion.
