Claim 0:
1. A gesture recognition apparatus recognizing a gesture of a user and performing interface control associated with the recognized gesture, the gesture recognition apparatus comprising:
a processor which, by executing instructions, function as:
an image capturer that sequentially captures distance image data taken by an imaging apparatus in which a user has been imaged, and outputs the input image data and the distance data on a display screen;
a closest point detector that detects, from the distance image data displayed on the display screen, a closest point from the imaging apparatus;
a gesture measurer that calculates an input switching border, which is currently displayed with the distance image data, a tracking area associated with recognizable gestures, a gesture guideline, and an origin of the gesture, for switching ON and OFF of interface input, based on a trajectory of the closest point that is the gesture of the user detected from a plurality of distance image data items;
a gesture recognizer that determines whether the input is ON or OFF, in accordance with the input switching border; and
an interface controller that performs the interface control associated with the gesture when it is determined that the input has been turned on, wherein
the gesture measurer detects start point of the gesture of the user as the origin and an OFF side of input, and
the gesture recognizer determines ON or OFF of input by determining whether the detected closest point resides in a space that includes the origin relative to the input switching border.
