Abstract: A remote control system includes an object detection unit, an object determination unit, and a static gesture processing unit. The object detection unit detects an object corresponding to an operator according to a depth image including the operator and a face detection result corresponding to the operator. The object determination unit utilizes a combination of a gesture database, a color image of the object, and a two-dimensional image corresponding to the depth map to determine a gesture formed by the object when the operator moves the object to a predetermined position. The operator moves the object to the predetermined position and pulls the object after the operator moves the object to the predetermined position within a first predetermined period. The static gesture processing unit generates a first control command to control an electronic device according to at least one static gesture determined by the object determination unit.
