This just very cool in a very nerdy sort of way. I kinda wish it was less gimmicky, on the other hand I assume bump uses the time stamps of the shake and the key down to figure out which two devices are trying to talk. I wonder what the threshold for collision is?
Anyway, very cool and I could actually see a use for this, sending photos of whiteboards to colleagues that don't run Mac/have an iPhone. Would have to compete with email/dropbox for ease of use, but it does seem very simple on the receiving end, just surfing to a web page.
- vailripper 15y agoIt's also using HTML5 browser location to narrow that tap down to a fairly small area. Pretty neat idea.
- marcusf 15y agoYeah, that's true. I thought I wrote that as well but seems I erased it :) From experience, the accuracy on my browser location can be quite low, but I guess if you have (x,y,t) on both devices and a relatively large distance in the vector between bumpers it really doesn't matter.
- stellar678 15y agoI didn't approve the request for browser location, and it still worked flawlessly.
- dfc 15y agoHow do you know what web page you are supposed to "surf to"?
- marcusf 15y agoI was thinking in the case I'm standing next to him and just want to give him the file (I just photographed a whiteboard, for example). There's a ton of different, valid ways to send that file, but this is certainly one.
- bherms 15y agoBump is known for their ingenious methods of relating lots of data to figure out which two phones were being bumped at the same time (there's a really cool answer on Quora about how they do it). I would assume this is their tech team figuring out how to apply the same techniques across two devices (browser/pc -> phone). I bet there is some really cool stuff at play here.

- bherms 14y agoI think that may be the one I read.
- marcusf 15y agoThis is exactly why it feels so sexy. I took some courses in sensor fusion at university, and this is a very cool distributed application. Being able to create reliable "Bump-distance" vectors given all the variance with a distributed clock (though they seem to push the clock to the client in the browser), and with the position given by the browser etc. Very cool.
