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 solely 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,wherein the event determination unit is configured to determine the rolling of the wrist as a pointer activation or deactivation event, and is configured to determine the rolling of the wrist as click events during pointer deactivation,wherein the inertial sensor unit is disposed on single wrist, andwherein the event determination unit;

    is configured to determine the rolling of the wrist as a pointer activation event when the rolling of the wrist is generated in one direction in a pointer stopping state and determine the rolling of the wrist as a pointer stopping event when the rolling of the wrist is generated in another direction at a pointer activation state, andis configured to determine the rolling of the wrist as a left click event when the rolling of the wrist is generated to the left and then, is generated and recovered to the right within a set time and determine the rolling of the wrist as a right click event when the rolling of the wrist is generated to the right and then, is generated and recovered to the left within the set time.
