A keyboard having a touch input device includes a keyboard body and a touch input device. The touch input device is disposed on the keyboard body and is used in a digital input mode. The touch input device has a touch pad and a pattern layer. The pattern layer is bonded to a surface of the touch pad, and has a plurality of key indication areas. Each key indication area is corresponding to a key used in the digital input mode, for being recognized and selected by a user. In addition, through a switching module disposed on the keyboard, the digital input mode can be switched to a cursor control mode, a gesture control mode, or a handwriting input mode, thereby achieving a wide range of applications.

A pointing device includes: a magneto-electric transducer for detecting a variation in magnetic field of a magnetic element carried on an operator due to movement of the operator relative to an original position and for generating a voltage signal based on a detection result made thereby; a sampling unit for sampling the voltage signal to generate a sampling voltage; and a processing unit operable to generate a control signal corresponding to the movement of the operator upon detecting one of that the sampling voltage is not within a voltage range and that the sampling voltage is within the voltage range while a displacement of the operator from the original position is greater than a predetermined distance. A method of enabling a pointing device to generate a control signal is also disclosed.
