Olaf Schlieper, Innovation Manager and Accessible Tourism lead at the German National Tourist Board (DZT — Deutsche Zentrale für Tourismus), presented the organization's mixed reality app showcasing Germany's 55 UNESCO World Heritage Sites for Meta Quest and Pico VR headsets. The presentation marks a significant milestone in destination marketing, shifting from passive screen-based inspiration to fully immersive, interactive spatial experiences under the motto 'Walk the place before you go.'
The DZT's journey into extended reality began in 2018, progressing through several platforms: the Oculus Go with 360-degree panoramic content, the Microsoft HoloLens for showcasing castles and palaces, a Metaverse nature experience on Meta Quest 2, and now the UNESCO mixed reality walkthrough app. The platform also integrates an AI-powered digital travel companion named Emma.
The app's interface centers on two key interactive objects: a table for browsing or alphabetically searching all 55 UNESCO sites, and a door that transports users into the selected heritage site. Once inside, users can walk around in six degrees of freedom, interact with the environment, take quizzes, view 2D photo galleries, and read or listen to audio descriptions of each site. Social features allow up to six users simultaneously to take guided group tours together remotely.
Accessibility was a core design pillar — not merely a compliance requirement. The app automatically adjusts to the user's height, accommodating children, wheelchair users, and tall individuals. It offers adjustable text sizes, text-to-audio reading, color blindness modes, no sudden flashlights or strong emotional effects for those with sensory sensitivities, and head-control navigation for users with limited hand mobility (such as electric wheelchair users who can only operate a joystick). The project recently won the German Digital Responsibility Award, one of Germany's highest honors for digital accessibility.
Distribution spans the DZT's 22 international offices, UNESCO World Heritage Sites in Germany themselves, universities and third-party organizations, and free downloads on Meta App Store, Pico (mainland China) and Pico International. A major new channel announced at the presentation: the DZT will become the first national tourist board to feature in an in-flight VR entertainment program, partnering with Lufthansa on long-haul flights. Given that 5–9 billion people fly globally per year, this represents enormous addressable reach, and testing on long-distance flights confirmed strong passenger enthusiasm.
Engagement metrics stand out sharply compared to traditional digital channels. At events, users spend 5–15 minutes in the experience on average. At home, average session length reaches 30 minutes — a figure Schlieper described as 'a dream' when compared to TikTok campaigns 'where you fight for seconds of awareness.' The planned operational lifespan of the app is approximately four years, making the economic investment highly favorable. Schlieper positioned the project not only as a marketing tool but as a knowledge-sharing asset and a technical foundation for the next generation of lightweight smart glasses entering the market.
Um, we've talked a lot about AI this morning, right? With a lot of different perspectives. We talked about infrastructure, we talked about the tech fragmentation, distribution, MCP service and all these things. But now let's shift from theory to experience and uh we invited someone that will talk to us about what if you could walk through a destination before you ever bought the plane actually like you can experience it beforehand. What if inspiration wasn't just visual but really immersive? Lik...
