OK, someone help! How do you know whether a Bluetooth beacon is to the north or south of your phone?
Ask me to describe the influence of technology on urban culture and I can riff all day. But ask me to figure out something that sounds even vaguely like a grade 8 math problem and I freeze up.
So I’m asking for your thoughts. Here’s the use case:
- I have a beacon that I put on my dog’s collar. It’s Bluetooth LE although maybe it has an accelerometer as well.
- My phone has an app that detects the beacon.
- Now, since my phone also has a compass and can detect my strides and distance travelled, you’d think there’d be some way to figure out based on a rough probability that my dog, who usually travels ahead of me, is to the north (or south).
But how would you tackle this challenge? Without adding other devices for triangulation – and knowing we have the beacon on the dog, the GPS, compass, stride and direction detection on the phone – can we, in theory, figure out a way to make a high probability guess as to whether my dog is to the north or south of me? Is there any way to know with certainty?
