Case Study: NTT DATA enables indoor navigation for visually impaired visitors with Sewio Networks UWB RTLS

Providing Valuable Navigation in Crowded Environments to the Visually Impaired with Ultra-wideband Indoor Positioning

NTT DATA worked with Sewio Networks on a proof of concept to help visually impaired visitors navigate a large 20,000-capacity indoor arena in London. The goal was to make it easier for people with visual difficulties to find allocated seating in a crowded, echoey environment.

Sewio Networks and Locatify used an ultra-wideband indoor positioning setup with an Android navigation app and a haptic feedback device from NTT DATA. The system provided turn-by-turn guidance with 30 cm real-time accuracy, and the case study says the proof of concept showed the technology could deliver reliable navigation in challenging crowded spaces.
