VR: Virtual Reality learning materials of the future
A few days ago, I had the opportunity to try out one of the glasses that a shop had shown at a trade show. Interestingly, the glasses were made out of paper and were inexpensive. when trying to wear glasses I was very excited about the pictures I saw. The image was so real as if I was in the scene. So I started to feel interested and studied more until I learned that in 2014 Google developed a ton of cardboard cameras that look like binoculars and called Google Cardboard when they brought the phone. It is mounted on the front of the camera and looks through the viewfinder. Will see the image in three-dimensional virtual reality after that, various companies have developed several models and models in the form of glasses to wear under the name VR Glasses
The working principle of VR glasses is similar to that of a 3D vision machine. (stereoscope), which is used as a geographic device to view three-dimensional terrain.
Combining the working principle of a 3D camera with powerful, high-resolution display capabilities will get a realistic three-dimensional display device that has the following working principles.
Let’s start with creating a still image or animation in dual 2D. The easiest way is Visualization of sensory perception in the brain by allowing the eye of the eyeglass wearer to see different images at the same dimension and creating a slight disparity between the image seen with the left eye and the right eye through a lens that enlarges the image. and then adjust the picture to be more clear that is seeing two different images but seeing the same picture with a natural look The viewing distance must be set appropriately apart. not to be seen as a blur to prevent eye fatigue.
with advances in technology Creating a 3D image is no longer a hassle. In the new smartphones, there are many application developers to help you take 3D photos. There are also applications that display 3D stills and animations, such as google’s Cardboard Camera using 3D demos, or Mobius Networks’ VR Cinema, which can display 3D images in an instant. for a more realistic vision
There are also additional integrations for other sensory systems, such as providing realistic sound effects through speakers or headphones. Make VR glasses wearers feel like they are in real life for the benefit of a wide range of applications, whether it is education, military, medical, virtual reality games. including providing new ideas for use in the future
Google is now launching Expeditions, an educational VR project. The aim is to give children the opportunity to explore the world through Google Cardboard, which is also compatible with other VR glasses. Testing began in September 2015 in the United States, Canada, Denmark and Singapore. Google Cardboard is used in conjunction with a smartphone. to test the media used to support teaching in the future Interested parties can go to learn more at Google for Education as the Expeditions program.
For education in Thailand, we also have a lot of knowledge that we cannot take students to study in real places or events. This may be a dangerous place located far away. or not present, such as the habitat of dinosaurs Stars in the universe, volcanic eruptions, etc. VR glasses will be a new learning medium that will bring students to experience those events as if they were in real events. This will allow learners to learn and understand more deeply than just looking at pictures in textbooks or looking at two-dimensional images. This article is a part of NSTDA Magazine.
