Airports are hard places to navigate, especially if you speak little-to-no English. We have created a mobile app people can scan their boarding passes with, and will connect to a tracker located on the handlebars of luggage trolleys (which also have a space to put your phone in to see) that will connect to sensors based around the airport. The sensors will find the location of the tracker, and then the tracker will send directions to the app to get to the gate it needs to get to.
