This is really easy to do.
At a hackathon in 2012 our team in just a few hours built tech that would detect who you were standing next to or walking past, all while your phone is in your pocket - we were trying to build a tool that would replace exchanging business cards at conferences.
- granduh 8y agoCan you go into more detail with how that worked?
- netsharc 8y agoNot OP, but I'm guessing signal strength measurements, so if 2 devices report similar values they must be close to each other. And then just add the gyroscope info.
- chrononaut 8y agoThat's an interesting suggestion. I'm curious if the body position as it relates to the closest antenna and the phone, particularly if the RF energy has to pass through the owner's body, would add too much noise when compared to the person if they're standing facing the closest antenna.
- dangoldin 8y agoHave you heard of Bump? They were doing something similar until they were acquired by Google: https://www.theverge.com/2013/9/16/4736860/bump-acquired-by-google https://www.theverge.com/2013/9/16/4736860/bump-acquired-by-...
- trjordan 8y agoThey're basically the Google Photos team, now. Have you seen the ads about face recognition and auto-sharing? They've been working on the problem of photo sharing ever since they figured out that people didn't want to share contact info with Bump, they wanted to share photos.
- dangoldin 8y agoDidn't know that but makes a ton sense. Also surprisingly how Instagram became Instagram when they realized all it was being used for photo sharing. People love their photos.
