1. An apparatus for inputting information based on events, comprising: an inertial sensor unit configured to sense a rolling of a wrist and a motion of a hand; an event determination unit configured to determine the events through the rolling of the wrist sensed by the inertial sensor unit; a coordinate calculation unit configured to calculate a moving displacement for the motion of the hand sensed by the inertial sensor unit; and a control unit configured to transmit control commands corresponding to the events and transmit coordinate values for the moving displacement input from the coordinate calculation unit, when the event determination unit determines the rolling of the wrist as the events.
