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.

Abstract
Disclosed are an apparatus and a method for inputting events. An embodiment of the present invention can generate left and right click events in addition to activating and stopping pointers by sensing a rolling of a wrist and calculate and output a coordinate displacement according to the motion of the hand at the time of activating the pointers according to the events. Further, the embodiment of the present invention can be applied to a large-sized display or a contactless spatial input apparatus of an HMD, entertainment such as games, and the like, and can overcome restricted environments by a gesture input scheme under special environment.
