    Abstract: Disclosure is related to a cursor control apparatus and a method for controlling the cursor. The cursor control apparatus essentially includes a light-emitting unit for emitting lights, a housing having a light passage thereon, a light-sensing unit and a control unit. The lights are emitted to outside the apparatus via the light passage. The light-sensing unit then receives the reflected lights from a surface via the passage, especially the lights reach a plurality of sensing cells arranged in an array. The control unit is used to control the energy of the emitting lights, and control the light-sensing unit to receive the lights. After that, the energy received by every sensing cell in an interval can be computed and find the spatial interference difference of energy. The difference is made to determine a moving direction, for example the cursor's movement with the movement of user's finger around the light passage.

In particular, the coherent light may be preferably used in order to enhance the interference effect. In an exemplary embodiment, the method includes firstly the sensor pixels in the sensor chip receiving the reflected light, and calculating the energy. Next, within a time slot, the energy state of each sensor pixel can be calculated. A moving vector may be determined from a difference between the binary energy states of the adjacent sensor pixels.
