1. A gesture input system, comprising:
- a two-dimension (2D) image sensor, obtaining a plurality of images of a user; and
a processing module, determining positions of an object and a face of the user in a first image of the plurality of images, determining an operation area for the user according to the positions of the object and the face in a 2D plane corresponding to the plurality of images, determining a trigger area within the operation area and in the 2D plane, determining a first contact relation between positions of the object in the subsequent images and the trigger area in the 2D plane, and generating a first control command according to the first contact relation,wherein the first contact relation is one of a plurality of predetermined types of first contact relations comprising;
the object moves from the outside of the trigger area to the inside of the trigger area through a side of the trigger area in the 2D plane, and then moves from the inside of the trigger area to the outside of the trigger area through the side of the trigger area in the 2D plane; and
the object moves from the inside of the trigger area to the outside of the trigger area through a side of the trigger area in the 2D plane, and then moves to the inside of the trigger area through the side of the trigger area in the 2D plane.

Abstract
A gesture input system with a two-dimension (2D) image sensor and a processing module is provided. The 2D image sensor obtains a plurality of images of a user. The processing module determines positions of an object and a face of the user in a first image of the plurality of images, and determines an operation area for the user according to the positions of the object and the face. Also, the processing module generates a control command according to the subsequent images to the first image of the user within the operation area.
