When used, data stored in the storage unit 1 is read out to the reading unit 2 and is explained later by the data synthesis unit 3. Is combined with the data from the determination unit 10. Of the combined data, the video data is input to the video forming device 4 (LCD or the like) to be converted into a video, and is projected onto the user's eyes by the display device 5. Of the synthesized data, the audio data enters the audio forming device 6 and becomes audio, and is output from the speaker 7.

  This head mounted display includes a receiving unit 8, and the receiving unit 8 wirelessly receives information output from the external device 9. The term “wireless” includes not only radio waves but also other normally used signal propagation means such as infrared rays. When the determination unit 10 receives the signal from the reception unit 8 and matches the signal set in advance, the determination unit 10 calls the corresponding data from the notification information stored in the notification information storage unit 11, and the data synthesis unit 3. And is combined with the data from the reading unit 2. As a result, in addition to the video information and audio information stored in the storage unit 1, notification information (video, audio) extracted from the notification information storage unit 11 is output to the display device 5 and the speaker 7. Become.

  At this time, as a method of synthesizing the information from the storage unit 1 and the notification information storage unit 11, information in which both are superimposed may be formed, and the information from the notification information storage unit 11 is output. Information from the storage unit 1 may not be output.

  The information extracted from the notification information storage means 11 may be displayed only for a predetermined time, or it may be displayed until a signal that is erased by the user's operation is input. May be. Further, when the user operates to delete, the notification may be performed again after a predetermined time has elapsed. In FIG. 1, video and audio signals are used as notification signals, but only video signals may be used without using audio signals. Conversely, the video signal may not be used as the notification signal, but only the audio signal may be used.

  As the receiving unit 8, a receiver that receives information from an external device 9 that generates radio waves or infrared rays is generally used, but this receives an external landscape image as an external signal ( An imaging device for imaging) may be used. The imaging device may be provided with a small one on the back side of the surface facing the eye of the display unit 21 in FIG. When the video imaged by the imaging device matches a prestored pattern, the determination unit 10 calls the corresponding data from the notification information stored in the notification information storage unit 11 and sends it to the data synthesis unit 3. The data from the reading unit 2 is combined.

  Similarly, a voice recognition device such as a microphone that collects external voice as an external signal can be used as the receiving unit 8. 10, when the voice detected by the voice recognition device matches the pattern stored in advance, the corresponding data is called from the notification information stored in the notification information storage means 11 and sent to the data synthesis unit 3. The data is combined with the data from the reading unit 2.

  Further, instead of the receiving unit 8, an acceleration or vibration detection device that the head mounted display receives due to an external influence of the user can be used. When the signal detected by the acceleration or vibration detection device matches a prestored pattern, the determination unit 10 calls the corresponding data from the notification information stored in the notification information storage unit 11 and sends the data to the data synthesis unit 3. The data is sent out and combined with the data from the reading unit 2.

  Further, as the receiving unit 8, two or more of these receivers, imaging devices, voice recognition devices, acceleration or vibration detection devices are used, and these are switched in the setting so that the above functions are performed. May be. In addition to the video stored in the storage unit, the head mounted display may be capable of displaying a television broadcast video, for example.

  Hereinafter, application examples of the head mounted display which is an example of the embodiment of the present invention will be described. FIG. 2 shows an example in which a user who is observing an image of a head-mounted display on a train informs that the next stop is Nishioi Station. There is a stop station information server 12 in the train vehicle. When it is transmitted that the next stop station is Nishi Oi Station at an appropriate notification timing, it is transmitted from the transmitter 13 as a radio wave.

  It is received by the receiving unit 8 of the head mounted display 14 used by the user, and the next stop station is displayed on the display screen and the headphones of the head mounted display 14 through the process described above. It is announced by display and utterance that it is Nishioi Station.

  At this time, only when the user's exit station is notified, the determination unit 10 may perform control so as to notify the next stop station, and whenever the stop station is notified, You may make it announce all the notification stations. In addition, the head mounted display does not notify immediately when it is received by the receiving unit 8, but does not notify until an appropriate time has elapsed from the expected stop time transmitted from the stop station information server 12, You may make it announce when it becomes the time.

  FIG. 3 shows an example in which a microphone built in a headphone detects contents broadcast from a broadcasting device installed in a station or in a vehicle. When there is a broadcast pattern in the detected information that the next stop is Nishi-Oi Station, the following information is displayed on the display screen of the head mounted display 14 and the headphones through the process described above. It is notified by display and utterance that the stop station is Nishioi Station.

  If the receiving unit 8 has an imaging device, it captures information on the next stop station displayed in the vehicle, and outputs the next stop station to the display screen of the head mounted display 14 and the headphones based on the captured information. To do.

  Further, when an acceleration sensor or a vibration sensor is used as the receiving unit 8, the number of train stops is counted by these sensors, the next stop station is detected by the number of times, and the display screen and head of the head mounted display 14 are detected. Output to the horn.

  In either case, the video display and the output from the headphones may be stopped when a predetermined time has elapsed, or may be stopped by a user operation. Further, the video display method may be changed with the passage of time. For example, the luminance of the video is increased or the size is increased with the passage of time. Similarly, the audio output may be increased with the passage of time.

  Moreover, if the display is as follows, it becomes easier for the user to draw attention, and it is easier for the user to recognize the notification reliably. The display method is such that the character or graphic information displaying the notification content is superimposed on the already displayed information and moved largely within the display area of the head mounted display 14, or the information already displayed. The contrast and brightness are repeatedly changed after being superimposed on the. In addition, the above-described video change may be given by replacing the already displayed information. In the case of performing such image processing, in the example of the present embodiment, the information generated from the determination unit 10 input to the data combining unit 3 is combined by the data combining unit 3 so that the display position changes with the display time. By controlling the image data and sending the image synthesized by the data synthesizing unit 3 to the video forming device 4, the notice information can be displayed while drawing the user's attention.
