Abstract:
A pointing stick device comprising:a substrate; a rectangular-shaped hollow structure installed on the substrate and 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 having at least one claw, the claw structure being used to impart a pressure onto the rectangular-shaped hollow structure and curve the rectangular-shaped hollow structure, wherein the claw structure is located above the rectangular-shaped hollow structure and a pole is fixed to an upper side of the claw structure; wherein 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; and wherein when the pole is pushed, the claw of the claw structure imparts the pressure on the rectangular-shaped hollow structure to cause the strain gauge to produce the corresponding pointing signals.
