Using an array of disorganized smartphones, it would be possible if GPS accuracy was good enough to make each smartphone function as a pixel.
If everyone held their smartphone up high with a special app. They can synchronize a video to all the smartphone. If there is enough, then you have a massive video display.-- mofosyne, Aug 19 2013 gps pantograph description Pantographic_20smartphone_20shoes [not_morrison_rm, Aug 19 2013] Audio-synchronized crowdsourced display and sound http://www.hypebot....ert-mobile-app.htmlDan Deacon's concerts feature an app for iOS and Android. [Cedar Park, Aug 20 2013] Gps accuracy is nowhere near good enough but I bet they could figure out a way to distribute video signal to a bunch of phones that know of eachother where they are, so yeah bun.-- zeno, Aug 19 2013 Sounds like another use for the pantographic mobile phone wossername, but this time like a periscope. Given a 10:1 ratio the GPS accuracy should be pretty good, and the mobile phone screen would be bounced between the periscope mirrors. If that makes any sense.-- not_morrison_rm, Aug 19 2013 This could still work without GPS provided that everyone remained in their assigned seat. The incentive would be that if you want to sit on the floor in the center, you have to abide by certain rules.-- Jscotty, Aug 19 2013 [+] To locate everyone without GPS, a "coordinator" phone could capture a few seconds of video of the array at the same time that the displays are individually sequenced through with some kind of calibrating image (all red screen). If you know you sent a particular phone a red screen at a particular time, a video of the gang could be used to resolve the locations.-- the porpoise, Aug 20 2013 A cheaper way to do the "seat" location display, is to place a QR code in front of each seat. Where each website page is for a particular seat, and represents a single pixel.
So therefor no app install needed. :D-- mofosyne, Jan 22 2015 A cheaper way to do the "seat" location display, is to place a QR code in front of each seat. Where each website page is for a particular seat, and represents a single pixel.
