I have the following use case:
Given a set of points in a space, I would like to use a smartphone to detect and locate the closest point (Possibly accurate to the at least a meter range)
I am not familiar with this field myself, so I would like to know if you have some input on how to get started with the research.
For example, in your opinion:
- What would be the best technology to use? Bluetooth, GPS, NFC
- What's the cheapest option to use for the devices? And what would be the overall best option regardless of price?
Thanks in advance for any input, please let me know if I need to clarify something or add more information.
