Abstract: A keyboard able to recognize fingertip touches and touches in gestures such as fingertip sliding, in addition to simple presses on keycaps, includes a plurality of keycaps, a touch layer, a function trigger layer, a touch controller, and a function controller. Each keycap has an operation surface for receiving the pressings and touches. The touch layer generates touch sensing signals according to the touches, the function component generates key signals according to the pressings. The touch controller obtains touch information from the touch sensing signals. The function controller triggers desired key functions according to the key signals received. A method for making such keyboard is also disclosed.

Abstract: An electronic device includes a detachable base and a monitor housing detachably mounted on the detachable base. The detachable base includes a main body, at least one sensor, a keyboard, and a driving circuit. The driving circuit is electrically coupled to the keyboard and the at least one sensor. When the at least one sensor detects the monitor housing placed on the detachable base, the at least one sensor sends a driving signal to the driving circuit, and the driving circuit triggers an input function of the keyboard.

Abstract: A method to communicate the effects of physical touches made to a touch screen includes acquiring touch information from a touch screen of a first device which is touched and controlling a touch screen of a second device to simulate effects of the touch applied to first device. The method utilizes piezoelectric elements, pressure sensors, temperature sensors, and temperature adjusting devices installed in the touch screens of both devices. A tactile interaction device is also provided.
