Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a notebook pointing stick testing device. Background Art

[0002] The laptop is equipped with a pointing stick (commonly known as Little Red Riding Hood). When external force is applied to the pointing stick, the ceramic sheet at the bottom of the pointing stick will immediately deform slightly, and the resistance of the ceramic sheet will change accordingly, thereby generating different electrical signals. The circuit analyzes these different electrical signals to determine the different movement directions and speeds of the mouse pointer. In fact, the pointing stick is a joystick-style operation. Currently, the pointing stick is capacitive. After the pointing stick is assembled together with its circuit board, its performance needs to be tested to ensure that the same pressure can be recognized in all directions of the pointing stick under the same pressure, otherwise the sensitivity of different areas of the pointing stick will be different.
