Abstract: A touch-control system includes at least two image capturing units and an electronic device. The image capturing units are configured to capture a plurality of hand images of a user. The electronic device is coupled to the image capturing units, and configured to recognize a target object from the hand images, and detect motions of the target object in an operating space. The electronic device includes a display unit, and the operating space includes a virtual touch-control plane. When the target object touches a virtual touch-control point on the virtual touch-control plane, the electronic device generates a touch-control signal and performs an associated touch-control operation at a position corresponding to the virtual touch-control points on the display unit.

Abstract: A keyboard device includes an operation surface. One long side of the operation surface is referred to as a proximal side, which nears a user operating the keyboard device; and the other long side is referred to as a distal side. A key unit is positioned on the proximal side, wherein the key unit includes a plurality of keys. A camera module is positioned on the distal side. An angle between a border of a field of view of the light sensor and the operation surface is set at a particular angle thus user's hand lays outside the field of view of the light sensor when the user is manipulating the key unit.
