Abstract: A system for fan interaction is disclosed including, in some embodiments, a fan-interaction module stored in a memory of a mobile device; a touchscreen display interface; and one or more sensors selected from a touchscreen sensor, an accelerometer, a gyroscope, and a global positioning system receiver. The fan-interaction module can be configured to: 1) provide a notification to a fan that an entity the fan supports is to perform or an event the fan supports is to occur; 2) log an interaction of the fan with the device regarding the entity ready to perform or the event ready to occur; 3) calculate an amount of kinetic energy associated with the interaction; and 4) provide the amount of kinetic energy to a server for combination with a combined amount of calculated kinetic energy for up to all fans of the entity ready to perform or the event ready to occur.
