IBM has released a mass card stunt app that allows crowds to display messages by coordinating their mobile devices.
Coordinating a successful card stunt can be the highlight of a sporting event for those involved. But doing so requires a high degree of coordination and is very difficult on a mass scale. IBM's new 'Card Stunt' app is a social platform that allows attendees of an event to link their mobile devices to display a cohesive message. With the touch of a button, event organizers are able to deliver these mass messages.
The app uses a phone's camera to detect motion and senses where other devices are located. Once the message is calibrated, members are able to leave the group and the sign will maintain legibility.
With this method, little preparation is required. Event-goers will receive notifications of when to flash their phones to be a part of the overall message.
