Abstract

A portable electrical input device capable of docking an electrical communication device is provided. The input device includes a docking base, image sensors, and a communication interface. The sensing regions of the image sensors define an operation region. An operation pattern is selectively configured in the operation region. The operation region is formed on an operation sheet or projected by an illuminating device. When an object operates in the operation region, the processor connected with the image sensors calculates a position information of the object according the sensed object image. The calculated position information is sent out through the communication interface.
