Rhomberg Bau Messe App

A trade fair experience that works when it matters

The Rhomberg Bau Messe App was created to turn a trade fair stand into a digital experience. It is built for visitors who stop, touch, explore, and move on. No instructions needed. No explanations required.

The application runs on a transparent OLED touch display and presents Rhomberg Bau’s services in a clear, visual structure. Content is accessible within seconds. Navigation feels natural. Interaction is immediate.

The app was designed for real trade fair conditions. People standing. Limited time. Changing light. Unstable connectivity. Every screen, transition, and interaction is optimized for speed and clarity.

A backend system allows content to be managed centrally and synchronized ahead of time. This ensures the app remains fully functional even without a stable internet connection. The result is a reliable, confident presentation tool that works exactly when it needs to.

Design and Engineering for Public Touch Experiences

Touch-first UX built for public spaces

The UX and UI concept was developed by die3, who defined the visual language, interaction logic, and narrative structure of the experience. Their concept established how content, motion, and the transparent display work together as a single system.

Webulos translated this concept into a production-ready application optimized for touch interaction. The interface is designed for hands, not cursors. Large interaction zones, clear hierarchy, and immediate feedback allow users to navigate instinctively.

The experience follows a simple structure. One clear entry point. Direct paths to content. Calm transitions. No visual clutter. The transparent OLED display supports the story instead of distracting from it.

All UX decisions were made with the environment in mind. Standing users. Short attention spans. Constant movement around the screen. The result is an experience that feels effortless, even in a busy exhibition hall.

Reliable web technology for offline-first scenarios

The application was built as a performant web app using React. It connects to a backend system that manages content and controls synchronization across devices.

Content is preloaded and cached to ensure smooth operation in environments with limited or unstable connectivity. Updates can be prepared in advance and deployed reliably on site.

The system architecture focuses on stability and maintainability. Clear separation between content, logic, and presentation allows future extensions without rework.

The result is a robust trade fair solution that combines visual impact with technical reliability. It performs under pressure and delivers a consistent experience throughout the event.
