Description

  The present invention relates to VR glasses, and more particularly, to VR glasses that allow a user to visually recognize a virtual reality three-dimensional space image by stereoscopically viewing a parallax image displayed on a display of a mobile terminal through a lens. And suitable.

  In recent years, the use of virtual reality (VR) technology that makes a virtual world created in a computer experience as if it were real is spreading. A goggle type HMD (head mounted display) is widely used as a device for displaying a three-dimensional space image by VR. A general VR head-mounted display includes a display for displaying a parallax image for creating a virtual three-dimensional space, and a lens for stereoscopically displaying the displayed parallax image for the user.

  On the other hand, what is called VR goggles that can realize a VR experience with a smartphone is also provided. The VR goggles are configured to include a holding unit for holding a smartphone and a lens for stereoscopically viewing a parallax image displayed on the display of the smartphone. The holding unit and the lens are provided at positions where a parallax image displayed on the display of the smartphone attached to the holding unit is appropriately projected onto the lens.

  VR goggles are much cheaper than VR head-mounted displays because they only have a lens attached to the goggles. The VR goggles can be folded and are convenient to carry. Therefore, it is used by many users. In particular, VR goggles constructed using a lightweight and inexpensive material such as cardboard are known.

  By the way, the size of the smartphone possessed by the user who uses the VR goggles varies. Therefore, the relative positional relationship between the display of the smartphone and the lens provided in the VR goggles changes depending on the size of the smartphone attached to the holding unit of the VR goggles. For example, if a smartphone with a smaller or larger size is attached to a holding part that is formed assuming a smartphone of a predetermined size, the relative positional relationship between the smartphone's display and the lens is the originally expected ideal Will shift from the correct position. In this case, the parallax image displayed on the display of the smartphone is not appropriately projected onto the lens, and there arises a problem that the three-dimensional space image of VR cannot be appropriately stereoscopically viewed by the user through the lens.

  On the other hand, VR goggles have been conventionally known in which the height of a holding unit for holding a smartphone can be adjusted up and down (see, for example, Patent Document 1). In the 3D image glasses described in Patent Document 1, as shown in FIG. 7, by attaching the smartphone to a holding unit whose height can be adjusted up and down, the relative positional relationship between the display of the smartphone and the lens is in an appropriate state. It becomes possible to set to.

  However, in the VR goggles described in Patent Document 1, a holding portion is provided at the middle position of the left and right lenses, and the central portion of the smartphone is attached to the holding portion. Therefore, the central part of the display is closed by the holding part, and the area of the closed part cannot display an image. Further, with the structure described in Patent Document 1, the image projection space between the display and the lens is completely divided into left and right with the holding unit as a boundary. Therefore, the parallax image displayed on the display in the region on the right side of the holding unit is not projected on the lens in the region on the left side of the holding unit, and is similarly displayed on the display in the region on the left side of the holding unit. The parallax image is not projected onto the lens in the region on the right side of the holding unit.

  Due to the VR structure of the VR goggles as described above, the parallax image to be displayed on the display must be created in a special manner in accordance with the VR goggles characteristics. The parallax image created in such a special manner has a problem that it cannot be used except for the VR goggles described in Patent Document 1 and has poor versatility.

  The present invention has been made to solve such a problem, and a partial area of a display included in a mobile terminal held by VR goggles is shielded by a holding unit, or between a display and a lens. An object of the present invention is to make it possible to adjust the height of the holding unit for holding the portable terminal up and down without the image projection space being divided by the holding unit.

  In order to solve the above-described problems, in the present invention, the left and right vine portions are connected to the left and right ends of the main body portion holding the left and right lenses via a connector, and the side opposite to the main body portion of the vine portion is provided. Are provided with a terminal holding unit. Moreover, in this invention, it is set as the structure which hold | maintains the coupling tool which connects a main-body part and a temple part in the aspect which can be rotated in the left-right direction and can be moved to an up-down direction.

  According to the present invention configured as described above, since the mobile terminal is held by the left and right vine portions outside the left and right lenses, a partial area of the display of the mobile terminal is shielded by the terminal holding portion. There is no end. According to the present invention, since the terminal holding unit does not exist in the image projection space between the display of the mobile terminal and the left and right lenses, the image projection space is not divided by the terminal holding unit. . And since the temple part is hold | maintained by the coupling tool for connecting a main-body part and a temple part in the aspect which can be rotated in the left-right direction and can move to an up-down direction, the terminal holding part provided in the temple part Can be adjusted up and down. Thereby, according to the size of a portable terminal, it becomes possible to set appropriately the relative position of the display with respect to a lens.
