Social, Local, Mobile.
I'm really excited about iBeacon. It opens up tons of different business opportunities in AEC, BIM, 3D, CAD , GIS, Retail, Social, Games, and more! Suddenly we can connect to our enviroment, we can know when we are near "beacons".
Allows people to do new things, and do things better. To me - this is particularly exciting for workplaces, find/connecting with your colleagues.
I'm curious to see what @Hover is thinking about - they claim "smart sensors for the workplace", this is what iBeacon gives you so im curious to what their envisaged workflows are.
