Pointing Stick is a pointing device mainly used in laptops. Different laptop manufacturers often refer to their Pointing Stick products
differently, with ThinkPad referring to them as "Track Point" and Dell referring to them as "Track Stick". When external force is applied to
the pointing rod,it immediately causes slight deformation of the ceramic plate at the bottom of the pointing rod and the resistance of
the ceramic plate changes accordingly, resulting in different electrical signals. By analyzing these different electrical signals, the circuit
can determine the different direction and speed of mouse Pointing Stick movement.With one index finger,you can control the cursor to
move freely on a two-dimensional screen based on direction and force. Pointing Sticks were once favored by typists because they were
one of the few pointing devices that could manipulate the mouse without moving the finger away from the reference key . Unlike
modern touchpads, the small red hat allows for uninterrupted long-distance mouse movement without the need for multiple
operations, saving work time and improving work efficiency . Pointing sticks make portable laptops truly portable , not incomplete .
It saves a mouse by improving cursor operation efficiency and improving typing and input speed like editing documents.
