How does a laptop s touchpad work?

Hehe, if your hands are too cold, you can't use them.

It is estimated that it is the principle of thermal induction.

I agree that it is the principle of pressure.

I think it's surface waves (surface sound waves), but of course the nails are hard, and the wavelengths produced when they come into contact are different. Only respond to a certain range, otherwise it will not be good to respond when something touches.

The principle of pressure sensitivity. related to the contact area. It's not too light.

1. Click Actions. Clicking with one finger is equivalent to using the left mouse button; Clicking with two fingers is equivalent to using the right mouse button.

Touchpads can also be found on other portable devices, such as PDAs and some portable audiovisual devices. Due to design limitations, touchpads are usually no larger than 20 square centimeters. Among them, the Apple MacBook Pro is equipped with the most excellent multi-touch trackpad, which can be used for gestures such as screen zoom, as well as for handwriting input.

The touchpad is free of mechanical wear, the control accuracy is also good, and most importantly, it is very convenient to operate, it is easy for beginners to get started, and some mobile PCs even extend the function of the touch template to a handwriting tablet, which can be used for handwriting Chinese character input. However, the disadvantage is that if the user's fingers are wet or dirty, it is not so easy to control.
