How to scroll up and down using the trackpad wps

In this way, use the touchpad wps to scroll up and down, directly press and hold the touchpad to drag the scroll bar on the right side of the web page or file, and drag it up and down. Touchpad is a widely used input device in notebook computers. Which controls the action of the pointer by sensing the movement of the user's finger. The touchpad can be regarded as a substitute for the mouse. Touchpads can also be found on other portable devices, such as personal digital assistants and some portable audio-visual devices.

Introduction to touchpad

The touch panel is composed of printed circuit boards in rows, and the printed circuit boards and the plastic film on the surface are bonded with strong double-sided tape. Its inductive detection principle is capacitive induction. The special integrated circuit board under the surface of the touchpad will continuously measure and report this trajectory, thus detecting the movement and position of the finger.

Touchpad is an input device that moves the cursor on a smooth touchpad through the sliding operation of fingers. Can make it easy for beginners to get started. Because the thickness of the touchpad is very thin. So it can be designed on an ultra-thin notebook computer or keyboard. It is not a mechanical design.

Maintenance is very simple. Its working principle is that when the user's finger approaches the touchpad, the capacitance will change, and the control IC of the touchpad will detect the capacitance change and convert it into coordinates. The touchpad is sensitive to the heat of fingers through capacitive induction.
