Touchpad

 =Laura Stapleton   Touch pad                   A touch pad is a computer device that typically mimics the functions of a computer mouse. Instead of having a external mouse the touch pad enables the user to use one or multiple fingers being dragged across relative positions on a sensitive pad! Ill tell you how it works! To scroll down u usually move your finger up or down on the right side of the touch pad. To click u simply tap the touch pad.Then to move the arrow around on the page you simply move your finger on the touch pad to the direction u would like it to go! Its that simple and a lot easier on the wrist, believe it or not! =

The more we find about Technology the more it Grows. We used to use Mouses and we still do but on Laptops have Touchpads.

If something like a finger is placed between the transmitter and receiver some of the field lines are cancelled out.

This system uses a high frequency to transfere a signal so that the mouse pointer will move throughout the monitor of the computer.

A series of pads that signals can be passed through and is seperated by an insulator and is crossing each other at a right angle to form a grid. The signal that is passed through the pads is proportional to the capacitance.When a solid object, such as a finger, is placed onto the touchpad a signal is passed through the touchpad and into the computer to move the mouse pointer.**     <span style="COLOR: #8600ff; FONT-FAMILY: 'Comic Sans MS', cursive"> <span style="COLOR: #000000; FONT-FAMILY: 'Comic Sans MS', cursive">**b.) The touchpad senses a change in capacitance between the pads. The transmitter creates an electric field that sends an eletric shock, like a message, to the monitor. If a finger or a solid object touchs between the transmitter and the receiver, some of the shockes are deleted or shunted away, which decreases the shock that is sent into the monitor to move the mouse pointer.

If you don't know some of the words in this paragraph, then you can look below and I will give most of the definitions. Frequency- an electricity wave Capacitance- being able to collect a charge of electricity**
 * Shunt- delete**

<span style="COLOR: #000000; FONT-FAMILY: 'Comic Sans MS', cursive"> A **touchpad** (also **trackpad**) is a pointing device  consisting of specialized surface that can translate the motion and position of a user's fingers to a relative position on screen. They are a common feature of laptop computers and also used as a substitute for a computer  mouse where   desk space is scarce. Touchpads vary in size and are mainley found on laptops ipods and mp3’s. <span style="FONT-FAMILY: 'Comic Sans MS', cursive"> These are some examples of touchpads
