I am working with a client who wants us to build a web and mobile application that will be able to track user locations on a map as the customer moves around the building (through different exhibit halls, etc) for the purpose of assisting in way finding - and I am trying to find the best way to achieve this.
I know I won't be able to use the mobile phone GPS to get as precise as we'd want to get. What's the best solution to be able to do this? We need to be able to track users as they move between floors, in and out of rooms, etc.
We do not have access to the devices, as we're hoping that customers will bring their own mobile phones.
