PixMob
PixMob is a wireless lighting technology that controls wearable LED devices. By transforming the wearable objects into pixels, the crowd becomes a display. The light effects produced by the LED devices can be controlled to match a light show, pulsate in sync with the music, react to the body movement, etc.
PixMob was developed by a Montreal-based company named Eski Inc. in 2010. The technology comes in different versions that provide different ways to wirelessly control any of the objects. The latest version, PixMob VIDEO, debuted during the Super Bowl XLVIII Halftime Show.〔Zach Sokol (March 21, 2014) ( PixMob: Turning Crowds Into Light Canvases ) The Creators Project〕〔Jackson Gallagher (February 5, 2014)( How 82,529 Hats Became a Video Screen For Super Bowl XLVIII ) Live Design Online〕〔Liz Stinson (February 5, 2014)( How 80,000 People Became a Human Video Screen at the Super Bowl ) Wired〕
== Technology ==
PixMob technology uses infrared to light up RGB LEDs that are embedded in different objects such as balls or wristbands.〔 These wearable objects are given to an audience, transforming each individual into a pixel during the show.〔 To light up each pixel (i.e. each LED), commands are sent from computers to transmitters that emit invisible light (infrared).〔 The infrared signal is picked up by infrared receivers in each object and goes through a tiny 8-bit microprocessor to light up the LEDs. The type of transmitter involved differs depending of the version of the technology chosen. Wash fixtures or lekos, typically seen in the live entertainment industry, are usually used. For the PixMob video technology, VT transmitters beam video instructions onto the audience, almost like a matrix creating a virtual map. With this technology, the infrared receiver decodes the signal differently depending on each pixel/person’s location. This enables the creation of animated video effects and transforms the audience into a display screen.〔 Despite the low-resolution result due to a low number of pixels, quite detailed video effects can be achieved on a large canvas, using bright colors and bold movements.〔
