In the Prefabricated House World Wuppertal, the interconnected, energy-positive houses were designed to be emotionally experienced. The installation in the entrance area attracts visitors, makes the topic accessible, and increases dwell time and interaction as measurable goals.

The 5-meter-long projection surface presents the four elements abstractly and reacts to movement. As a result, four seamlessly connected panels are ready to attract visitors and encourage conscious play.

Two D-Imager sensors create point clouds, a Java middleware synchronizes both views, and ThreeJS renders the shapes in WebGL. This creates feedback that transforms random passing into conscious manipulation and establishes a sensual connection to the topic of energy.

The greatest impact came from the combination of a large format, visible moments of randomness, and very finely controllable reactions. This created an inviting low-threshold experience that quickly transitioned into intentional play and emotionally anchored the topic of energy.
