For the 100th anniversary of the Czechoslovak Republic, in cooperation with Czech Centers, we created the very first exhibition where one could actually say that there was nothing there, except for a few VR headsets and some 28 special AR pictograms (targets) printed on white walls. Using VR and AR technology, the exhibition presented Czech inventors and their great innovations. As visitors pointed the cameras of their mobile devices towards the targets on the walls, our AR app instantly revealed the basic outline of the great inventions in schematic 2D and 3D animations. In the virtual reality section, visitors were immersed into differently stylized environments where some past inventors told their stories about how and under what circumstances they came up with their discoveries.
