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.
