Abstract

Provided is a head-mounted display in which it is easy to photograph eyes of a user that wears the head-mounted display. The HMD that is worn by the user includes a display unit disposed in front of the eyes of the user, an optical system disposed between the display unit and eyes of the user, and an imaging unit disposed between the display unit and the optical system, the imaging unit imaging the display unit in which an image of the eyes of the user is reflected.

Claims

1. A head-mounted display worn by a user, comprising:

a display unit disposed in front of eyes of the user;

an optical system disposed between the display unit and the eyes of the user; and

an imaging unit disposed between the display unit and the optical system, the imaging unit imaging the display unit in which an image of the eyes of the user is reflected.

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

a light-irradiation unit that irradiates light onto the eyes of the user,

wherein the imaging unit images an image of the eyes of the user reflected in the display unit by reflecting the light irradiated by the light-irradiation unit by the eyes of the user.

3. The head-mounted display according to claim 2, wherein the light-irradiation unit is disposed between the optical system and the eyes of the user and directly irradiates light onto the eyes of the user.

4. The head-mounted display according to claim 2, wherein the light-irradiation unit is disposed between the display unit and the optical system and irradiates, onto the eyes of the user, reflected light in which light irradiated onto the display unit is reflected.

5. The head-mounted display according to claim 2, wherein the light-irradiation unit irradiates infrared light, and the imaging unit is an infrared camera capable of imaging the infrared light.

6. The head-mounted display according to claim 1, further comprising:

a line-of-sight detection unit that detects a line-of-sight direction of the user on the basis of an image including the image of the eyes of the user imaged by the imaging unit.
