The mobileProtest device allows people to spread information about a cause they support without the commitment of a direct action protest. Organizations register their cause with locations on a map which individuals can sign up to support. As the individual wearing the device goes about their day, messages for nearby causes are broadcast on the device to the public. If enough supporters for a cause are near a location, the devices shift from broadcasting a message to rallying others by alerting nearby supporters of an impromptu protest or flash mob. It involves the global, local, and public communities.
