ShadowGrid
The floor that knows exactly where you are
ShadowGrid is an indoor positioning system that uses shadow-detecting floor tiles to map precise locations in retail spaces and malls. By detecting the unique shadow patterns of each person moving through the space, the system enables accurate, camera-free indoor navigation and foot traffic analytics—without any app or hardware required from shoppers.
The Wow Moment
You're in a mall searching for a specific store. Instead of pulling out your phone and staring at a map, the floor tiles beneath your feet subtly illuminate a path ahead of you—the system detected your shadow, knows exactly where you are, and is guiding you forward with light patterns that respond to your movement. It feels like the floor itself is alive and helping you navigate.
