Claim:
1. An optical pointing device for detecting a finger's direction of a user, comprising: a cover, comprising a press portion and a side wall, the press portion having a first surface and a second surface opposite the first surface, the side wall extending downward from the periphery of the second surface, and the press portion and the side wall are two separate elements; a light source, projecting a main beam to the press portion of the cover, wherein the main beam then forms a first beam passing through the press portion and a second beam reflected by the second surface; and a sensor, being adapted to receive the second beam reflected by the second surface, and detect the second beam by an algorithm to output a first displacement position; wherein the light source and the sensor are covered by the cover, and the side wall is a flexible side wall, and the side wall is deformable according to a horizontal movement of the press portion.
