I’m a huge fan of the works of SuperUber. To create the mood in a party to celebrate the launch of Audi TT in São Paulo, Brazil, they developed two multimedia projects, Super Bar and Interactive Shadows. They had the help of Muti Randolph, which created the images and cenography to the party. The Super Bar uses a camera with a sensor to create a very long touchscreen interface. When someone puts a glass our touches the bar, the point is connected with lines to other points. The lines create connections between the objects and hands over the bar.
The other installation, Interactive Shadows (Sombras Interativas) was located at the entrance of the party, and was meant to be an introduction to what was to come. The people could interact with the images projected, in a way that the profile of the person acted as a mask, revealing the hidden footage. These interactive projections are a revolution, allowing the guest to interact with the projections using movements of his body.
Check out the video:
Both projects use a camera with a sensor that films the silhouette and movement that are interpreted by the computer using proprietary software. The result is then shown back to the person, as a projected image.
