Abstract: Some embodiments present wearable devices that communicate with other like devices via wireless signals and respond to them based on criteria that the wearer controls. According to some embodiments, the wearable devices are bracelets that allow wearers to identify, primarily by way of multicolored light displays, others based on specific criteria relating to an event or specific need. These criteria are also useful for allowing the bracelets to be controlled by a single coordinator who creates an event for the wearers to opt into (e.g. the arena manager at a sports game, the emcee at a wedding, the coordinator of a meet and greet event, etc.).
