Abstract

The present technology enables a user wearing a head-mounted display having a display section provided in front of the eyes of the user to directly check a state in front of the user. A head-mounted display includes: a display section; a casing supporting the display section in front of eyes of a user; and an optical system supported by the casing, the optical system allowing the user to view an image of an object disposed in a rear of the display section as viewed from the user.

Claims

1. A head-mounted display comprising:

a display section;

a casing supporting the display section in front of eyes of a user; and

an optical system supported by the casing, the optical system allowing the user to view an image of an object disposed in a rear of the display section as viewed from the user.

2. The head-mounted display according to claim 1,

wherein a hole is formed in the casing, and

the optical system includes a mirror that can open and close the hole.

3. The head-mounted display according to claim 2, further comprising

a video output control section controlling output of video by the display section,

wherein the video output control section limits the output of the video by the display section when the hole is opened.

4. The head-mounted display according to claim 2, further comprising

a position control section controlling a position of the mirror such that the position of the mirror becomes a position of closing the hole or a position of opening the hole, according to whether or not a predetermined condition holds.

5. The head-mounted display according to claim 4,

wherein the predetermined condition is a condition related to a position or attitude of the head-mounted display, a condition related to brightness of video displayed on the display section, or a condition related to magnitude of a detected sound.

6. A display control method of a head-mounted display,

the head-mounted display including

a display section,

a casing supporting the display section in front of eyes of a user, the casing having a hole formed in the casing, and

an optical system including a mirror that can open and close the hole, the optical system being supported by the casing, and the optical system allowing the user to view an image of an object disposed in a rear of the display section as viewed from the user,

the display control method comprising:

limiting output of video by the display section when the hole is opened.

7. A position control method of a head-mounted display,

the head-mounted display including

a display section,

a casing supporting the display section in front of eyes of a user, the casing having a hole formed in the casing, and

an optical system including a mirror that can open and close the hole, the optical system being supported by the casing, and the optical system allowing the user to view an image of an object disposed in a rear of the display section as viewed from the user,

the position control method comprising:

controlling a position of the mirror such that the position of the mirror becomes a position of closing the hole or a position of opening the hole, according to whether or not a predetermined condition holds.
