Description

VR glasses

The present invention relates to glasses for VR, and more particularly to VR glasses for enabling a user to visually recognize a three-dimensional space image of virtual reality by stereoscopically viewing a parallax image displayed on a display of a portable terminal through a lens. Preferred.

In recent years, the use of virtual reality (VR: virtual reality) technology that allows a virtual world created in a computer to experience as if it were a reality 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 typical VR head mounted display is configured to include a display for displaying a parallax image for creating a virtual three-dimensional space, and a lens for causing the displayed parallax image to be stereoscopically viewed by the user's eyes.

On the other hand, there is also provided what is called VR goggles that enables a smartphone to realize a VR experience. The VR goggles are configured to include a holding unit for holding a smartphone, and a lens for causing the parallax image displayed on the display of the smartphone to be stereoscopically viewed by the user's eyes. The holding unit and the lens are provided at positions where the parallax image displayed on the display of the smartphone attached to the holding unit is appropriately projected on the lens.

VR goggles are very cheap compared to VR head mounted displays because they are only lenses attached to the goggles. Also, VR goggles can be folded and convenient to carry. Therefore, it is used by many users. In particular, VR goggles configured using lightweight and inexpensive materials such as cardboard are known.

By the way, the size of the smart phone which the user using VR goggles possesses is various. 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, when a smaller or larger smartphone is attached to a holding unit formed assuming a smartphone of a predetermined size, the relative positional relationship between the display of the smartphone and the lens is the ideal originally expected It will deviate from the normal position. In this case, the parallax image displayed on the display of the smartphone is not properly projected on the lens, and a problem arises in that it is not possible to appropriately stereoscopically view the three-dimensional space image of the VR through the lens.

On the other hand, VR goggles are conventionally known in which holding portions for holding a smartphone can be adjusted in height up and down (see, for example, Patent Document 1). In the glasses for three-dimensional image described in Patent Document 1, as shown in FIG. 7, the relative positional relationship between the display of the smartphone and the lens is appropriate by attaching the smartphone to the holding portion capable of adjusting the height up and down. It becomes possible to set to.

Design registration No. 1559871

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

Due to the peculiarity of the structure of the VR goggles as described above, parallax images to be displayed on the display also have to be created in a special manner in accordance with the peculiarities of the VR goggles. And, there is a problem that the parallax image created in such a special mode can not be used other than the VR goggles described in Patent Document 1, and becomes poor in versatility.

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

In order to solve the problems described above, in the present invention, the left and right temples are connected to the left and right ends of the main body holding the left and right lenses via a connector, and the opposite side to the temple of the main body And the terminal holding unit. Further, in the present invention, the connector for connecting the main body portion and the temple portion is configured to be held in such a manner that the temple portion can be turned in the lateral direction and movable in the vertical direction.

According to the present invention configured as described above, since the portable terminal is held by the left and right temples outside the left and right lenses, a partial area of the display of the portable terminal is shielded by the terminal holding unit There is nothing to lose. Further, according to the present invention, since the terminal holding unit does not exist on the image projection space between the display of the portable terminal and the left and right lenses, the image projection space is not divided by the terminal holding unit. . Then, since the hook portion is held in a horizontally pivotable and vertically movable manner by the connector for connecting the main body portion and the hook portion, the terminal holding portion provided on the hook portion You can adjust the height of the up and down. This makes it possible to appropriately set the relative position of the display to the lens according to the size of the portable terminal.
