We divide proximity technologies into complimentary categories - those for absolute and those for relative location interactions.
- Absolute location defines your geo position and is expressed in terms like latitude and longitude.
- Relative location defines your position relative to real-world objects and is expressed in terms like distance from x.
We've provided a few charts to simplify the comparison of leading proximity technologies in terms of absolute and relative locations. Here's how we compare location services:

So how does this relate to real-life interactions?
