There is a selection-operating area, a gesture-operating area, and a key-in area above the keyboard. The image-detection module is embedded in the keyboard for detecting the location of the user's hand. The processing device informs the electronic device to operate in either the selection-operating mode, the gesture-operating mode, or the key-in mode, according to the location of the hand as detected by the image detector. ## Claims ### Claim 1 An input device for an electronic device, comprising: a keyboard, wherein there is a selection operation region, a gesture operation region, and a keyboard input region on top of the keyboard; an image-detection module, embedded in the keyboard, detecting a position of a hand; and a processing device notifying the electronic device to operate in either a selection operation mode, a gesture operation mode, or a keyboard input mode, according to the position of the hand as detected by the image-detection module. ### Claim 2 (depends on 1) The input device of claim 1, wherein: the processing device notifies the electronic device to operate in the gesture operation region so that the electronic device operates according to a gesture of the hand when the hand is in the gesture operation region as detected by the image-detection module; the processing device notifies the electronic device to operate in the selection operation region so that the electronic device operates according to the gesture when the hand is moved into the selection operation region from the gesture operation region as detected by the image-detection module; and the processing device notifies the electronic device to operate in the keyboard input mode so that the electronic device operates according to a input information of the keyboard when the hand is not detected by the image-detection module. ### Claim 3 (depends on 1) The input device of claim 1, wherein the keyboard has an operation surface and there is a virtual plane which is above as well as on the leading edge of the electronic device, and which is substantially vertical to the operation surface, wherein the gesture operation region and the keyboard input region are sequentially located between the virtual surface and the operation surface, and the virtual plane is at a junction of the selection operation region and the gesture operation region. ### Claim 4 (depends on 3) The input device of claim 3, wherein the processing device notifies the electronic device to operate in the keyboard input mode when the hand is located in the keyboard input region. ### Claim 5 (depends on 3) The input device of claim 3, wherein the image-detection module is embedded in the leading edge of the operation surface of the keyboard and tilted at an angle so that the position of the hand may not be detected by the image-detection module when the hand is on the operation surface of the keyboard. ### Claim 6 (depends on 1) The input device of claim 1, wherein the image-detection module has two image detection units which are placed on both sides above the keyboard. ### Claim 7 An electronic device, comprising: a display; a keyboard, wherein there is a selection operation region, a gesture operation region, and a keyboard input region between the top of the keyboard and the display; an image-detection module, located between the keyboard and the display, used to detect a position of a hand; and a processing device operating in either a selection operation mode, a gesture operation mode, or a keyboard input mode, according to the position of the hand as detected by the image-detection module. ### Claim 8 (depends on 7) The electronic device of claim 7, wherein: when the hand is in the gesture operation region as detected by the image-detection module, the processing device operates in the gesture operation mode and controls a screen shown on the display according to a gesture of the hand; when the hand is in the selection operation region as detected by the image-detection module, the processing device operates in the selection operation mode and selects an object on the screen corresponding to the position of the hand, or moves a cursor corresponding to the position of the hand as detected by the image-detection module; and when the hand is not detected by the image-detection module, the processing device operates in the keyboard input mode and a input information of the keyboard is shown on the display. ### Claim 9 (depends on 7) The electronic device of claim 7, wherein the keyboard has an operation surface, and the area between the operation surface and the display is divided into three regions which are in the order of the selection operation region, the gesture operation region, and the keyboard input region, and a junction of the selection operation region and the gesture operation region is the virtual plane. ### Claim 10 (depends on 7) The electronic device of claim 7, wherein the processing device operates in the keyboard input mode when the hand is in the keyboard input region. ### Claim 11 (depends on 7) The electronic device of claim 7, wherein the image-detection module is embedded in a leading edge of an operation surface of the keyboard and tilted at an angle so that the position of the hand may not be detected by the image-detection module when the hand is on the operation surface of the keyboard. ### Claim 12 (depends on 7) The electronic device of claim 7, wherein the image-detection module has two image detection units which are placed on both sides above the keyboard. ### Claim 13 (depends on 7) The electronic device of claim 7, wherein the image-detection module is embedded in the keyboard and near a junction of the keyboard and the display. ### Claim 14 (depends on 7) The electronic device of claim 7, wherein the image-detection module is embedded in the display and near a junction of the keyboard and the display.
