Definitions

  • the present invention relates to a video and audio reproduction apparatus, and more particularly to a video and audio reproduction apparatus using a head mounted display.
  • AR Augmented Reality
  • AR is a technology that combines the real world and virtual reality, and since it is a content that can be used outdoors as, for example, portable game software, it is better than VR. It is expected to be a big market.
  • AR is also called Mixed Reality, and it is created by real images taken with a camera and computer graphics by placing an environment recognition camera and a space recognition camera in the head mount display housing.
  • a holographic optical technology is also put to practical use, which combines an image with a video image in real time and displays the image on a microdisplay again.
  • the image display device is a light shield type used for VR and a transmission type used for AR You can understand the outline of HMD.
  • VR is mainly used indoors from the viewpoint of safety.
  • AR uses a transmissive display and is safe, but it is unsuitable for viewing dynamic images of 360 degrees because of limited viewing angle.
  • VR is required to have a high immersive feeling of FOV over 100 degrees
  • AR is used for PC applications such as character recognition even if FOV is about 50 degrees and the field of view is narrow, in order to combine virtual reality in the real world High resolution is required because there are many cases.
  • the video and audio reproduction apparatus of the present invention is A reproduction circuit unit capable of reproducing virtual reality content and augmented reality content; A control circuit unit that selects one of the virtual reality content and the augmented reality content and causes the reproduction circuit unit to reproduce the selected content; A first display unit for displaying an image of virtual reality content; A second display unit for displaying an image of augmented reality content; And a head mount mechanism capable of attaching and detaching the first display unit and the second display unit.
  • an audiovisual reproduction apparatus including: A reproduction circuit unit capable of reproducing virtual reality content and augmented reality content; A control circuit unit that selects one of the virtual reality content and the augmented reality content and causes the reproduction circuit unit to reproduce the selected content; A first display unit for displaying an image of virtual reality content; A second display unit for displaying an image of augmented reality content; And a head mount mechanism capable of attaching and detaching the first display unit and the second display unit.
  • the first display unit displaying the image of the virtual reality content and the second display unit displaying the image of the augmented reality content are exchanged according to the content to be reproduced. It is possible to view and listen to both VR and AR content on one device.
  • the detection means automatically detects which of the first display unit and the second display unit is attached to the head mount mechanism, and according to the attached display unit, A screen for selecting VR content and AR content can be displayed. This saves the user the trouble of selecting which one of the VR content and the AR content to be reproduced.
  • the head mounting mechanism can be reduced in weight by providing the control circuit unit in the sound reproducing apparatus. As a result, it is possible to provide a video and audio reproduction apparatus with less fatigue even in long-term viewing.
  • the video and audio reproduction apparatus further includes, in the third configuration:
  • the sound reproduction apparatus includes an input device for inputting an operation instruction to the control circuit unit.
  • the video and audio reproduction apparatus further includes:
  • the sound reproducing apparatus further includes a position transmitting unit that transmits a position signal indicating the current position of the sound reproducing apparatus.
  • the video and audio reproduction apparatus further includes a position detection unit that detects a position signal transmitted from the position transmission unit.
  • the control circuit unit causes the first display unit or the second display unit to display the position of the sound reproduction device based on the position signal detected by the position detection unit.
  • a video and audio reproduction apparatus is the same as the fifth configuration.
  • the position transmitting unit is configured to transmit a beacon signal as the position signal.
  • the video and audio reproduction device further includes: The distance to the sound reproduction device detected by the position detection unit provided on the left side of the video and audio reproduction device, and the sound reproduction device detected by the position detection unit provided on the right side of the video and audio reproduction device
  • the control circuit detects the position of the sound reproducing device using the difference between
  • a video and audio reproduction apparatus is any one of the sixth to eighth configurations:
  • the control circuit unit causes the first display unit or the second display unit to display the distance to the position transmitting unit, which is a source of the position signal, as text.
  • An image and sound reproducing apparatus is any one of the first to tenth configurations: It further comprises a first microphone capable of detecting an external noise signal, and a second microphone capable of detecting an external audio signal.
  • FIG. 1 shows the concept of the HMD of this embodiment.
  • the VR unit 11 and the AR unit 12 are replaceable, and are joined by the AR / VR common unit 10 and unit engaging portions 14a and 14b.
  • the VR unit 11 and the AR unit 12 mainly include an optical module, and the AR / VR common unit 10 includes a signal processing circuit, a battery, an attitude detection sensor, and the like.
  • the unit engaging portions 14a and 14b are electrically coupled by a connector.
  • the input device is not limited to the controller touch panel unit 124 of the earphone unit 13.
  • a microphone or an infrared sensor may be used as the input device.
