To meet these two very distinct objectives, we designed two tailor-made holographic solutions, each using a different technology and perfectly integrated into its environment: At Invalides, we deployed a holographic pyramid with a diameter of 1 meter. This solution allowed a hybrid staging between the real product and an explanatory 3D animation. The guests were thus able to understand the inner workings of the intensifying tube with a level of clarity that is rarely achieved in this field. The interaction between real and virtual reinforced the “wow” effect while facilitating the understanding of the product. On the Eurosatory stand, we opted for a 65 cm Full HD holographic propeller, protected by a custom plexiglass bubble. This configuration offered a striking result, perfectly visible even in a dense and competitive environment. The protection allowed optimal safety, without perceptible mechanical noise, while respecting the aesthetic codes of the stand and ensuring a smooth integration into the overall layout.
