In December 2016, Verkehrshaus, the Swiss Transport Museum, the largest and most-visited museum in Switzerland, launched its multi-media museum guide with Xponia’s digital wayfinding featuring indoor and outdoor navigation. We were engaged to provide a multi-media mobile guide needed to accommodate the entire museum, including, not only all exhibitions, but the Filmtheatre, Chocolate Adventure, Planetarium. Access to the online ticket shop, event calendar, service facilities, and a vast range of multi-media content and social features were added and the app became a cutting-edge, before-during-after museum experience. Considering Switzerland´s multi-lingualism, both the app and the CMS are available in 4 languages, i.e. German, French, Italian and English.
