Microsoft announces eyeglasses of eyeglasses type capable of synthesizing full-color hologram by changing focus on a pixel-by-pixel basis

The hologram of the stereoscopic image technology often appearing in the movie world is being developed as a near future image device which turns into a display. A technology that can output holography by passing through a lensed terminal with eyeglasses released by Microsoft Research Institute "Holographic Near-Eye Displays", You can output full color hologram with high resolution and you can see the hologram clearly naked even for those who need vision correction such as myopia, hyperopia and astigmatism.

The type of hologram display "Holographic Near-Eye Displays" of glasses type is described in the following movie.

This glasses type terminal is "Holographic Near-Eye Displays". The eyeglasses outputted by the 3D printer have a laser generating device in the crane on both sides, and holography can be projected on the display.


The principle itself of the hologram itself is similar to the conventional technique, and it is said that it is possible to synthesize a plurality of Sub-holograms having different depth information and make it stereoscopic.


However, Holographic Near - Eye Displays has a wide field of view, and it can be changed from conventional hologram terminals in that focus can be changed on a pixel basis.


High resolution holography can output full color at maximum 260 Hz. In addition, the field of view in the horizontal direction is secured at 70 degrees.


Laser information is being processed at high speed rendering using GPU.


High-performance GPU rendering enables real-time holographic output. You can check the movie by moving the 3D model nullly.


Holographic Near - Eye Displays can change the focus in pixels. Even for people with myopia or hyperopia, by adjusting the focal length, you can correct your eyesight with Holographic Near - Eye Displays alone without correcting with eyeglasses.


It is also possible to focus on the portion where the crosshair cursor is aligned and to naturally blur other parts according to the depth.


The image on the bottom is an image image when a person with normal eyesight views the left, even small letters can be read clearly. On the other hand, the image on the right is an image in the case of astigmatism, characters are blurred in the horizontal direction and the vertical direction.


Holographic Near - Eye Displays can correct astigmatism. The left is normal view, the right is the one that reproduced the view of astigmatism ... ...


In the software processing of Holographic Near-Eye Displays, you can modify the turbulence of the astigmatic image at the same level as the normal visual acuity as the rightmost image.


In addition, Holographic Near-Eye DisplaysaberrationIt is also possible to modify. Distortion has occurred in the horizontal and vertical lines due to aberration in the image on the left, but using Microsoft's technology can eliminate distortion of the output image due to aberration on the right.


Holographic Near-Eye Displays reproduced the dragon's holography on the desk.


I output a character on a fictitious wall. "I" of the enlarged letter alphabet means that there is only 1 pixel between "·" and "|".


As you can see in the movie, Holographic Near - Eye Displays allows you to freely change the focus by dot unit by rendering with GPU.


Furthermore, a horizontal field of view of 80 degrees is secured by one eye on general lenses of the eyeglasses, and hologram can be generated within the range where human beings can handle information well.


Holographic Near - Eye Displays has succeeded in holographic output that overcomes the disadvantages of noise, low contrast, low resolution, and monochrome, which are common in conventional holography, by performing high - speed rendering using NVIDIA 's GeForce GTX 980Ti.HoloLensUnlike a huge headset, it is a Holographic Near-Eye Displays that has succeeded in miniaturizing to a glasses type, but at the moment holography synthesis requires a high-speed GPU using an external PC, so to the last It is said to be in the experimental stage. If the performance of the mobile terminal improves in the future, it will be a technology that can expect the future that you can use AR · MR (Mixed Reality) contents using holography simply by wearing glasses.
