Description

Virtual Reality Video Device for Educational Video Monitor}

The present invention relates to a virtual reality imaging device for an image monitor capable of observing a stereoscopic (3D) image or a virtual reality (VR) image by attaching to an existing 2D image monitor having a screen size of 8 "or more diagonally.

As elementary, middle, and high school textbooks are digitized, video monitors such as tablet PCs with a size of 8˝-20˝, based on a diagonal of 10 ”screen size, are being distributed to students instead of printed textbooks.

    These video monitors recently provide applications that can watch stereoscopic and virtual reality images for augmented reality images based on 2D images.

 However, stereoscopic images and virtual reality images cannot be observed with existing HMD or VR devices on large screens larger than 8 ".

That is, the stereoscopic image is combined with the left-eye image and the right-eye image into a single image using the left-eye magnification lens and the right-eye magnification lens, respectively, so that the left-eye image is observed by the user's left eye and the right-eye image is observed by the user's right eye. This makes it possible to experience a stereoscopic image due to the difference, but the screen size beyond 8 ”is outside this range.

In other words, the space spacing between the left and right of the person is 65 mm, and therefore the center optical axis spacing of the left, right lens and left and right stereoscopic pictures should be 65 mm. Therefore, the size of the image is 65 mm horizontal left and right based on an aspect ratio of 16: 9. It should be within 130mmx 73mm, which is twice the size of

That is, the horizontal size of the left and right stereoscopic screens cannot exceed 130 mm. For this reason, conventional virtual reality images and stereoscopic images are mainly 5,5 "smartphones (screen size, horizontal 130 mm x vertical 63 mm = diagonal 142 mm, area 8,190 mm2). I used a lot

 However, the size of educational video monitors used in schools is usually 10 ”video monitors (image size of width: length 4: 3 ratio 200mmX150mm vertical 250mm diagonal 30,000mm2).

The 16: 9 screen size is 218mm horizontal x 136mm vertical, and the diagonal is 260mm_ and the area is 29,648mm2.

 That is, the 10 "screen area is about 3,66 times larger than the 5,5" screen.

Therefore, on the screen of the image monitor that is 10 "or larger, the stereoscopic screen or the virtual reality screen 101 is partially displayed at an irregular position on the screen, such as the center, bottom, or corner of the screen, as shown in FIG.

Therefore, it is impossible to use it with existing HMDs or virtual reality devices that do not match the left and right spatial spacing of the user in an educational video monitor of 8 "or more that has a size of 65mmx2 = 130mm or more.

U.S. Patent Registration No. 9,804,402

 The present invention to solve the above problems

This is a further improvement of the US PAT NO 9,804,402 filed and registered by the applicant, to view stereoscopic and virtual reality images on tablet PCs, computer image monitors, etc. of 8 "or larger 20", which are larger screens than existing 5,5 "smartphones. In providing a means to do it.

The present invention is based on a 3D image and a 3D image, a video monitor with a screen size of 8 "or more that provides a virtual reality image.

It is provided in combination with one side of the image monitor, but with a lens plate provided with left and right lenses at the same interval as the human eye.

 And the fixing plate for coupling the lens plate to the image monitor

When used in the fixture and the horizontal support having the same length as the focal length of the left and right lenses

The lens plate and the horizontal support are moved upward and downward, but are composed of an adjustment device that adjusts the vertical position of the lens plate with a vertical support and an internal vertical support.

Also, the left and right moving devices are configured to move left and right on the lens plate, the horizontal support, and the upper and lower positioning devices.

 In addition, a hinge device and a right angle holder are configured for each of the above components as necessary.

The present invention as described above is to deploy a lens plate on the front of the image monitor having a screen size of 8 "or more that exceeds 65mm, which is a person's pupil spacing, but moves the lens plate up and down by the horizontal moving means.

 The lens plate is configured to move left and right by the left and right moving means.

That is, even if virtual reality images and stereoscopic images are provided at any position of the top, bottom, left, and right corners of the front side of the image monitor, the lens plate moves up, down, left, and right by the horizontal and vertical supports to move to the image position.

In addition, since the length of the lens plate is equal to the length of the horizontal support such as the focal length of the left and right lenses, the length to the image monitor is matched, and the focus is automatically adjusted without the need to adjust the lens focal length separately.

Therefore, the present invention provides educational effects by providing dinosaur images or providing virtual reality images as stereoscopic left, right eye public photos, or stereoscopic videos on any part of the image monitor while educating dinosaurs in digital textbooks. Can increase

In addition, the effect of additionally configuring the hinge device for each element of the horizontal support, vertical support, and fixation is convenient for viewing the stereoscopic and virtual reality images when using the present invention and for convenient storage in a thin film structure when tilting the present invention backward. There is

  In addition, a right angle holder provided for each component such as a horizontal support, a vertical support, and a fixed support is used while holding or moving the present invention while being mounted on an image monitor, or when moving, rotating up, down, left, or right, focusing on the left and right lenses. It has the effect of keeping it stable

 That is, the present invention is to simply attach and detach the existing 8 ”or more 2D image monitor to study the 2D-based textbook process, and then, if necessary, use the left and right lens plates to perform stereoscopic image or stereoscopic virtual reality education.

Therefore, in the present invention, 2D, augmented reality, stereoscopic images, and stereoscopic-based virtual reality education can be frequently selected and trained on a large image monitor of 8 "or more, and is easy to carry, store, and use.
