For the 100th anniversary of the Czechoslovak republic, in cooperation with the Czech Centers, we have created the very first exhibition where one can actually say that there is nothing there, except for the VR headsets and special AR ideogram targets printed on the walls. In this case, we again used both VR and AR technology. The exhibition presents Czech inventors and their great innovations. As visitors point the cameras of their mobile devices towards the targets on the walls, our AR app instantly reveals the basic scheme of the great inventions in schematic 2D and 3D animations. In the virtual reality section, visitors are taken to differently stylized environments where past inventors explain how and under what circumstances they came up with their discoveries.
