These video monitors provide 2D image-based augmented reality images, and recently, applications for viewing stereoscopic images and virtual reality images are additionally provided.

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

That is, the stereoscopic image combines the stereoscopic left-eye image and the right-eye image into one image using a magnifying lens for the left and a magnifying lens for the right eye, respectively. You can experience a stereoscopic image with the difference, but the screen size of 8” or more is out of this range.

That is, the distance between the left and right pupils of a person is 65mm, and therefore the center optical axis spacing of the left and right lenses and the left and right stereoscopic pictures should also be 65mm. It must be within the size of 130mm x 73mm in length, which is twice the size of

That is, the horizontal size of the stereoscopic screen for the left and right eyes cannot exceed 130mm. For this reason, conventional virtual reality images and stereoscopic images are mainly used with 5,5“ smartphones (screen size, width 130mmxlength 63mm = diagonal 142mm, area 8,190mm2). used a lot

However, the size of the educational video monitor used in schools is usually a 10” video monitor (video size of 4:3 horizontal: vertical ratio 200mmX vertical 150mm diagonal 250mm area 30,000mm2)

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

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

Therefore, on the screen of the video monitor that is 10″ or larger, as shown in FIG. 1, the stereoscopic screen or virtual reality screen 101 is partially displayed at an irregular position on the screen such as the center, bottom, or corner of the screen.

Therefore, it is impossible to use an educational video monitor of 8″ or larger with a screen width of 65mmx2=130mm or more with an existing HMD or virtual reality device that does not match the user's left and right pupil spacing.
