The high-tech products development institute under Kim Chol Ju University of Education has developed a mobile three-dimensional image virtual display and a general meteorological information measuring device which are helpful to education.
Generally, three-dimensional TV, 3D goggles, 3D program and material and technical means which can display images in a three-dimensional way are needed to show images in a three-dimensional way.
But the 3D image virtual display can show three-dimensional images virtually without 3D TV, giving lifelike representation of them to students.
“Research into using the 3D image virtual display based on the principle of light reflection in education has been encouraged and the display widely introduced into educational practice worldwide. At present, various means including four-face virtual display are introduced and generalized,” said Jong Se Yong, director of the institute.
But as the four-face virtual display is an immovable object, it is inconvenient to use in any place.
So, the institute made a mobile three-dimensional image virtual display which can be used in any lecture room and show not only 3D images but also ordinary multimedia presentations.
To produce marked 3D effects, researchers darkened the brightness of the surroundings by focusing on providing a stark contrast to images and used opaque material for side glass.
As the image that people see through the reflection glass is the reverse, an image reverse program is used to turn the 3D image round so that they can see the correct image.
The institute also designed and made the ultrasonic meteorological information measuring device for educational purposes which can be claimed to be an advanced technology in measuring meteorological information volume including wind speed and its direction.
“Unlike the previous wind direction and speed measuring devices, the new device can correctly measure the wind speed and direction by precisely calculating the time required for the transmission of supersonic waves that change minutely according to the wind speed with the help of one-chip computer,” said Kim Hyang Song, section chief of the institute.
According to her, this device is easy to make, has high accuracy and quick measuring speed and is not affected by any external environment and conditions.
The mobile three-dimensional image virtual display and general meteorological information measuring device were registered as national inventions in 2019.
