Who is this for?
This proximity chat system is especially useful for organizers of large-scale events who want to give visitors a playful, technology-driven way to interact based on how physically close they are to one another. It's also a strong reference for companies looking to have their own proof-of-concept built around wireless positioning, IoT networking, or real-time data processing. And it's worth a look for anyone curious how physical proximity between people can be translated into a digital experience without relying on GPS or fixed wiring.
What makes it special?
What makes this project stand out is the combination of high accuracy and scalability. Using Ultra-Wideband technology, the system measures the distance between participants down to a fraction of a decimeter and translates that physical proximity directly into digital interaction. Multiple portable units communicate with a central Raspberry Pi hub, which processes all distance data in real time and visualizes it through a clear web interface. Because the setup has already been deployed during large-scale SLVN Events, it has proven itself in a busy, real-world environment rather than just on a test bench.
