The Swissbau in Basel is the most significant meeting point for the building and real estate industry in Switzerland and one of the biggest trade fair in Europe. For the booth of Nussbaum, the manufacturer of mountings and systems for home automation, gardens and special applications, we wrote an interactive application, with which the visitor was able to, on the spot calculate, the drop in pressure in different situations. Likewise we produced an animation for the illustration of Nussbaum’s drinking water installation. The technical equipment was supplemented with four displays with Bright Sign Player, which allow a flexible content playout and two so called «Touch Overlays» with mini mac processors to capacitate normal displays for touch content.
