Abstract

A head-mounted display includes a left-eye display unit configured to display a left-eye image, a right-eye display unit configured to display a right-eye image, a display control unit configured to control screen display of the left-eye display unit and the right-eye display unit, and an interpupillary distance adjustment mechanism configured to adjust an interpupillary distance between the left-eye display unit and the right-eye display unit. In the head-mounted display, the display control unit allows the left-eye display unit and the right-eye display unit to display a signal pattern for interpupillary distance adjustment when the interpupillary distance is adjusted by the interpupillary distance adjustment mechanism.

Claims

1. A head-mounted display, comprising:

a left-eye display unit configured to display a left-eye image;

a right-eye display unit configured to display a right-eye image;

a display control unit configured to control screen display of the left-eye display unit and the right-eye display unit; and

an interpupillary distance adjustment mechanism configured to adjust an interpupillary distance between the left-eye display unit and the right-eye display unit;

wherein

the display control unit allows the left-eye display unit and the right-eye display unit to display a signal pattern for interpupillary distance adjustment when the interpupillary distance is adjusted by the interpupillary distance adjustment mechanism.

2. The head-mounted display according to claim 1, wherein the signal pattern for the interpupillary distance adjustment has a black and white geometric configuration having a pattern on a center and a periphery of eyesight.

3. The head-mounted display according to claim 1, wherein the signal pattern for the interpupillary distance adjustment is a left-eye pattern and a right-eye pattern having a geometric configuration of which black and white are reversed between the left-eye pattern and the right-eye pattern.

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

an external switch;

wherein

the display control unit starts processing for displaying the signal pattern for the interpupillary distance adjustment in response to user'"'"'s operation with respect to the external switch.

5. The head-mounted display according to claim 1, wherein the display control unit starts processing for displaying the signal pattern for the interpupillary distance adjustment in response to a start of an interpupillary distance adjustment operation by the interpupillary distance adjustment mechanism.
