Abstract
A pointing stick device has a substrate, a rectangular-shaped hollow structure installed on the substrate having a central axis substantially vertical to the substrate, at least one strain gauge installed on the rectangular-shaped hollow structure, and a claw structure. The claw structure has at least one claw, and is used to impart a pressure onto the rectangular-shaped hollow structure and curve the rectangular-shaped hollow structure. When the claw of the claw structure imparts pressure on the rectangular-shaped hollow structure, the strain gauge distorts, following the curve of the rectangular-shaped hollow structure, to produce corresponding pointing signals.
