Cube-type 3D display "gCubik" that allows you to view stereoscopic images from anywhere from 360 degrees

National Institute of Information and Communications Technology(Abbreviation: "NICT") has developed a cube-type 3D display "gCubik" that can reproduce stereoscopic images observable with the naked eye in a 10 cm square box. Improvements have been made so that stereoscopic images can be displayed on all sides of the box, observable from any direction of 360 degrees, display surface adopting touch panel, sensors and speakers that can measure posture and acceleration are also installed Therefore, it is said that it is possible to operate stereoscopic images with feeling like actually touching, interactive interactions and so on.

By the way it is the image of the ball that is reflected in the cube in the image above.

Details are as below.
Completed cube-type 3D display that can be observed from any direction of 360 degrees - Stereoscopic images in a box will be in your hand ~ | NICT National Institute of Information and Communications Technology

At NICT, we are pursuing research and development on various communication technologies that can acquire and reproduce high realistic sensation, and in addition to developing technologies for displays that can observe stereoscopic images with the naked eye without requiring special glasses, We are working on suggesting scenarios for dissemination of stereoscopic displays in the near future through examination of scenes using screens. This time cube type autostereoscopic display "gCubik" was born as part of it and is a completely new concept of 3D designed as a tool to support communication between people and people at a close distance to reach It is said to be a display.

This time, we displayed stereoscopic images that can be observed with the naked eye on all six sides of the cube-shaped gCubik and succeeded for the first time to realize the proposed concept of "there is a stereoscopic image in the box". Compared to previous systems, the brightness is tripled and the resolution is 1.4 times better, making it easier to see, making it as compact as possible by various ideas such as not arranging the control board etc. as much as possible on the 3D display part. It seems that it has become possible to actually have a stereoscopic image of about 10 cm square in size (weight 950 g).

In the box is a picture of a duck


In the future, we are planning to put into practical use such as interaction method unique to the concept "stereoscopic image that can be held", development of application that uses multiple gCubik in cooperation, further wirelessization, further miniaturization, image quality improvement We are going to do our work.

I hope I can do something like this in the future.


In NICTA floating touch display that allows you to move aerial images that are visible but do not exist with your fingertipsWe are also developing.


Examples of aerial images


Example of operation with fingertip


As a mechanism, while floating the screen of a liquid crystal display (LCD) placed under the element by the optical element developed in NICT arranged on the plane as an image in the air, the glassless infrared touch panel detects the fingertip position to touch the aerial image It is said that there is.

With this, it is possible to display the aerial image completely stopped in the air as if it were actually there even for the up, down, left and right viewpoint movement, and it is possible to touch the aerial image by touching it with the finger It seems to have become.

Incidentally, although there is still a problem that the size of the optical element is small and there is a limitation on the size of the displayable aerial image, this is not a matter of principle and it is a manufacturing technology problem, By advancing the development of technology, it is possible to aim for realization of human life-size video display three years later.
