Claim 5:
6. A gesture recognition method for recognizing a gesture of a user and performing interface control associated with the recognized gesture, the method comprising:
sequentially capturing, by an image capturer, distance image data taken by an imaging apparatus in which a user has been imaged, and outputting the input image data and the distance data on a display screen;
detecting, from the distance image data displayed on the display screen by a closest point detector, a closest point from the imaging apparatus;
calculating, by a gesture measurer, 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;
determining, by a gesture recognizer, whether the input is ON or OFF, in accordance with the input switching border; and
performing, by an interface controller, the interface control associated with the gesture when it is determined that the input has been turned on, wherein
detecting, by the gesture measurer, start point of the gesture of the user as the origin and an OFF side of input, and
determining, by the gesture recognizer, 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.
