Abstract

In a head-mounted display for blocking out an outside world from a user's vision when worn by the user to present a video, an outside world measurement section measures outside world information. A notification information detection section detects whether or not the information measured by the outside world measurement section contains any notification information to be notified to the user. A notification section notifies the user when the notification information detection section detects notification information.

First claim

The invention claimed is:

1. A head-mounted display for blocking out an outside world from a user's vision when worn by the user to present a video, the head-mounted display comprising:
an outside world measurement section adapted to measure outside world information;
a notification information detection section adapted to detect whether or not the information measured by the outside world measurement section contains any notification information to be notified to the user, including that the notification information detection section detects still objects as notification information; and
a notification section adapted to notify the user when the notification information detection section detects notification information by way of displaying a video of the still object to the user in the head-mounted display.

2. The head-mounted display of claim 1 , wherein
the outside world measurement section is a stereo camera with at least two cameras.

3. The head-mounted display of claim 2 , wherein when the notification information detection section detects a still object, the notification to the user by the notification section is triggered by the fact that the distance between the head-mounted display and the still object becomes shorter than a given reference distance.

4. The head-mounted display of claim 3 , further comprising:
a position measurement section adapted to detect a position of the head-mounted display,
wherein the notification section acquires the distance between the position of the head-mounted display and the still object based on the position of the head-mounted display detected by the position measurement section.

5. The head-mounted display of claim 1 , wherein:
the outside world measurement section is adapted to measure respective distances between the head-mounted display and the still objects; and
the user sets a reference position within the outside world from which the outside world measurement section is adapted to measure respective distances between the head-mounted display and the still objects.

6. An information processing method carried out by a processor of a head-mounted display for blocking out an outside world from a user's vision when worn by the user to present a video, the method comprising:
measuring outside world information;
detecting whether or not the measured information contains any notification information to be notified to the user, including detection of still objects as notification information; and
notifying the user when notification information is detected by way of displaying a video of the still object to the user in the head-mounted display.

7. A non-transitory, computer readable storage medium containing a computer program, which when executed by a processor of a head-mounted display for blocking out an outside world from a user's vision when worn by the user to present a video, causes the head mounted display to carry out actions, comprising:
by an outside world measurement section, measuring outside world information;
by a notification information detection section, detecting whether or not the measured information contains any notification information to be notified to the user, including that the notification information detection section detects still objects as notification information; and
by a notification section, notifying the user when notification information is detected by way of displaying a video of the still object to the user in the head-mounted display.
