The Swiss Transport Museum’s latest exhibition uses Panasonic Visual Solutions to create an immersive experience for visitors.

The exhibition, which opened in June 2014, takes visitors on a 25 minute long journey where they learn about the origins, manufacture and transport of chocolate. Visitors first enter a lift in the form of a shipping container which takes them on a virtual trip from the port of Hamburg to West Africa – one of the world’s largest cocoa producing areas.

After they exit the shipping container, visitors board one of ten wagons that navigate through the Chocolate Adventure. Along the journey, the wagons stop in different themed rooms and in front of life-like projections of chocolate industry experts, where large-scale projections provide a visual insight into what the expert is telling the audience.

A highlight of the journey is the intermezzo, during which all ten vehicles leave their stations to glide through the exhibition in a collective choreography. Accompanied by large-scale projections and sounds, the museum creates an experience that immerses the visitors in cocoa.


Ten Panasonic PT-DZ680 projectors are used in the exhibition, nine of which are fitted with the Panasonic ET-DL030 ultra short throw lens, which can reduce the projection distance required by 60% compared to conventional short throw projectors.

This ultra short throw capability was a large factor in deciding the best solution for the museum. The projections, the movement of the wagons, moving backdrops, themed rooms and sound are all part of a complex choreography that creates an immersive experience.

Valentin Spiess, CEO of iart company who made the conceptual design of the Swiss Chocolate Adventure said, “We were looking to create an immersive experience that is both entertaining and informative.

“We used short throw lenses for two main reasons: First, because they allowed us to realise large-scale projections in narrow spaces which would otherwise not have been possible. Second, because we could hide the projectors in the ceiling and out of sight from visitors.

“We also needed projectors with a low noise level, because they are installed directly above the audience. The Panasonic projectors definitely had the advantage. The whole solution was very appealing, there are other wide angle projectors on the market but their quality isn’t as good, either in terms of resolution, brightness or sharpness,” Valentin Spiess continued.

Panasonic’s Visual Solutions are also used in other exhibitions at the Swiss Museum of Transport. The i-factory exhibit offers an interactive experience which teaches visitors about the basic techniques that underlie information technology.

The central elements to the i-factory are four multi-user and multi-touch media tables. These are created by ceiling mounted projectors which projects onto the table via the use of a mirror.

“We needed a projector with low noise, a high WUXGA resolution and excellent sharpness for this application because the tables function as a touchscreen, with camera tracking from below,” said Markus Ottinger, Head of IT at the Museum of Transport. “In addition we needed the projectors to be reliable and robust because it runs 365 days a year.”

The Media Factory is another exhibition at the museum which offers visitors the opportunity to create their own TV shows. A combination of Panasonic’s Broadcast and Visual solutions are installed at the exhibition where visitors can experiment with the operating methods of television and broadcasting studios.
