Abstract: An electronic device is provided, including a housing, at least one tap sensing unit and a processing unit. The housing has a touch surface, in which, when the touch surface is tapped more than one time in a predetermined interval, shock waves are generated. The tap sensing unit receives the shock waves to generate a moire signal. The processing unit obtains a shock wave source number of each of the shock waves according to the moire signal, and generates a string code according to a generation order of the shock waves and the shock wave source number of each of the shock waves, such that the processing unit controls the electronic device according to a control command corresponding to the string code.

Abstract: A method for setting and cancelling a gesture operating region in a gesture control device includes steps of capturing at least one image; detecting whether there is a palm in the at least one image; if there is a palm in the at least one image, detecting whether there is a face in the at least one image; if there is a face in the at least one image, setting the gesture operating region according to the palm and the face; and cancelling the gesture operating region when the palm is at rest over a first time period or the palm disappears from the gesture operating region over a second time period.

Abstract: A dual-mode remote control method, adapted to an electronic apparatus having an image sensor, is provided. In the method, the image sensor is used to successively capture a plurality of images. Then, infrared ray (IR) detection and/or gesture detection is determined according to at least one characteristic of the images and performed on the images, so as to obtain an action of at least one target in the images. Finally, a control command corresponding to the action is executed.
