BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a goggle type display device will be described below. The following embodiments are preferable examples, and the goggle type display device of the present invention is not limited to the following embodiments.

FIG. 1 is a schematic view of the goggle type display device of this embodiment. Reference numeral 1 is a goggle type display device main body. A camera (eg:
A small CCD camera 2 is mounted, and the goggle type display device main body 1 is equipped with sensors 3, 4 and 5 which are means for detecting changes in the surrounding conditions. The sensor 3 is mounted on the front part of the goggle type display device body 1, and the sensors 4 and 5 are mounted on the ear hooks 1b and 1a extending from the goggle type display device body 1, respectively. Further, at both ends of the goggle type display device main body 1, vibrators 6 and 7 serving as means for notifying a result of detecting a change in the surrounding situation are mounted. Reference numeral 8 denotes a changeover switch, which is a switch capable of switching between notification / non-notification and switching between the image of the viewing source and the image of the camera 2. Although not shown, the goggle type display device body 1 has a built-in display for the user to view an image and a lens for enlarging and projecting the image displayed on the display to the user's eyes. ing. This allows the user to see as a large screen several meters away.

If the user of the goggle type display device wears the goggle type display device and enters a use situation, it becomes difficult to notice a change in the surrounding situation. The change in the surrounding situation is, for example, the approach of a person or the sound of the surroundings. By using, for example, a pyroelectric sensor as the sensors 3, 4 and 5 which are means for detecting changes in the surrounding conditions, it is possible to detect the approach of a person from the outside. In FIG. 1, the sensor 3 is in the front, the sensor 4 is in the left side, and the sensor 5 is in the right side. Although not shown, if a sensor such as a spectacles strap is provided and is attached so as to be connected to the ear hook 1a, rearward detection is also possible and it is possible to detect a situation change in the range of 360 °. Become.

Further, as a means for detecting changes in the surrounding conditions, it is possible to detect changes in the surrounding sounds by mounting a microphone in the parts where the sensors 3, 4, 5 are mounted. Therefore, it is possible to detect a sound that a person goes in and out, a sound of a telephone, and the like. Further, both the pyroelectric sensor and the microphone may be installed in combination.

When the approach of a person or the sound of the surroundings is detected by the means for detecting the change in the surroundings, the vibrators 6 and 7 provided in the goggle type display device main body 1 as the notification means for the user are operated, The vibration notifies the user of the detection result.

Further, as a notification means for the user, the video image being viewed is switched to the video image of the camera 2 to notify it.
Display (not shown) when surrounding conditions change
It is possible to visually check the surrounding change state by switching the image of (1) to the image of the camera 2 without removing the goggle type display device.

FIG. 2 is a configuration chart of the embodiment of the present invention shown in FIG. The operation of the embodiment of the present invention will be described below with reference to FIG. The goggle type display device is usually connected to a video deck or the like, and a viewing source such as an image reproduced on the video deck or the like is displayed on a screen (display) in the goggle type display device. The user wears the goggle type display device and views the image projected on the screen on a large screen. In some cases, you may also want to watch with headphones attached. When the power of the goggle type display device is turned on, the sensors 3, 4 and 5 mounted on the body of the goggle type display device and the camera 2 also mounted on the body of the goggle type display device are turned on, and the viewing source Appreciation of the video from is started. For example, sensors 3, 4,
Reference numeral 5 denotes a pyroelectric sensor, which detects the situation when a person approaches from the outside during viewing. The detection result can be informed / non-informed by operating the informing / non-informing switching section 8a of the changeover switch 8. As the notifying means, there is a means for notifying by vibrating the vibrators 6 and 7 and switching the image of the viewing source to the image of the camera 2.

The notification / non-notification switching unit 8a can separately select the notification by the image of the camera 2 and the notification by the vibrators 6 and 7. Therefore, if only the notification by the image of the camera 2 is selected, the sensor 3,
When 4 and 5 detect the approach of a person, what is displayed by the camera 2 is displayed on the screen of the goggle type display device main body 1 to notify it. Further, if only the notification by the vibrators 6 and 7 is selected, the notification is made only by the vibrations of the vibrators 6 and 7. Further, it is possible to select the notification of both the image of the camera 2 and the vibrators 6 and 7. The notification means can be selected according to the usage situation of the user.

When neither notification by the image of the camera 2 nor notification by the vibrators 6 and 7 is selected, even if the sensors 3, 4 and 5 detect the approach of a person, they are not notified. A normal image is displayed on the goggle type display device body 1 without vibrating. The user can freely select and use the above-mentioned switching according to the use situation.

Further, the changeover switch 8 is provided with a screen changeover unit 8b, and even if the sensors 3, 4 and 5 do not detect a change in the surroundings, the user operates the screen changeover unit 8a to operate the camera. It is also possible to project 2 images.

[0019]

When the goggle type display device is used, even if a change occurs in the surrounding situation, the change is not noticed. However, by mounting the detecting means and the notifying means, when the surrounding situation changes. I came to understand.

When using the goggle type display device,
From the beginning, when a person or the like is in the surroundings, the sensor detects and informs it, but by having a switch between informing and non-informing, it can be used according to the usage situation.

By mounting a camera on the goggle type display device, it is possible to see the surroundings without removing the main body when the surroundings change. I can take immediate action again.

Even if the user goes to sleep with the goggle type display mounted, the vibration is used to notify when a change occurs in the surrounding conditions, so that it can be dealt with.

When a change occurs in the surroundings, the camera image and vibration are used to notify the user, so that corrective action can be taken.
