An input device that adjusts its operation mode according to operation directions includes a movement sensing module, an operation direction control unit, a micro-control unit, and a transmission module. The movement sensing module for sensing a plurality of reflection images relative to a light source that is reflected by a reflection surface. Furthermore the movement sensing module obtains a movement displacement amount and a movement direction of the input device according to pattern variations between the reflection images. The operation direction control unit provides an operation direction of the movement sensing module. The micro-control unit converts the movement direction sensed by the movement sensing module according to the operation direction of the movement sensing module. The transmission module transmits the movement displacement amount and the converted movement direction of the input device to a host terminal so as to control a cursor displayed on the host terminal.
