As part of a hackathon team participating in the London Beacon Valley Hackathon in 2015, we were tasked to create a practical idea using Bluetooth beacon technology.
In just 24 hours, a working and demonstrable concept for an auditory guidance system where mobile phones can lead users through an airport using beacons as way-points was created and demonstrated successfully, leading the team to win first prize.
