I want to create wayfinder/pathfinder mobile application. it will route visitors in our buildings. we have 20 buildings and each at least have 4 floor.
We want to develop our own wayfinder ex:http://www.wayfinderkiosk.com/
It should use Lat/Long coordinates to locate the people. and help to find its route.
So where should i start. Does any one have any idea for that. and it is going to be mobile.
I can develop app/site based on these platforms ( Mobile Web/Iphone/Adroid /Symbian/Windows )
But i need a start point. and i need your help.
Thanks
You want to use lat/long inside of a building? Assuming these visitors are going to be using their own unmodified devices, you may have trouble with GPS. Unless you somehow get reliable GPS signal despite being under a four-story building, that's probably not going to work.
An RFID-tagged badge and sensors placed throughout the building seems more likely to work. Put a unique QR-code on each badge that directs the phone's browser to a tracking page for that specific badge.
edit: and now that I re-read your question and see that multiple buildings are involved, the GPS bit could certainly work for routing them from one building to another.
