Pokemon Go and Google Maps can make arrows and characters follow a map, why can't Loomo follow an internal map to guide people too? Other ideas for utilizing a GPS location tracking system came to mind too.
The idea was easy to come up with, but implementing it is definitely the hard part. For us, the challenge was in having no experience with creating android applications and thinking we needed to have some kind of semi-finished or finished product or program to present.
Knowing we could present ideas, throwing together a quick power point presentation with hours left to spare seemed like a pretty legit idea.
