Used for several years in the field of show and entertainment, holograms are now penetrating the educational world.
In that moment augmented reality is popular in education. This is a process that allows you to add multimedia elements (images, sounds, animations, visual effects, etc.) to real content. For its part, virtual reality also allows, for example, to rotate an image and zoom with great precision.
Developments in virtual and augmented reality have also made it possible to innovate on the holographic level. A hologram is the result of a photographic process that allows a three-dimensional image to be projected onto virtually any surface.
HoloLens: concretely visualize the concepts studied
Developed by Microsoft and currently used around the world, HoloLens is a kind of helmet allowing you to "see" holograms created from your computer. In education, its potential is particularly noted in the field of biology and medical sciences.
The holograms created by HoloLens can allow, among other things, to visualize a human body in 3D. Pupils who learn biology and anatomy can thus concretely visualize the concepts they are studying. Far from being trivial, the possibilities of augmented reality and holograms in the field of science are so great that, in several countries, these technologies are finding their place in medical schools. In the United Kingdom, we even think of replace traditional dissections with hologram simulations.
Some technology experts believe that the holographic technology could soon revolutionize the world of images.
A "homemade" hologram with a tablet!
In 2015, the Pixels team of the newspaper Le Monde successfully recreated a simple experience to learn about holograms. All it takes is a mobile tablet, a shiny transparent plastic sheet, internet access and a little geometry to achieve this. A great experience to do in class, detailed in the article. Although it is not exactly a hologram (it would then require lasers), the principle remains interesting!
