What is a USB Touchpad?
Hi
A USB touchpad adds a laptop-like pointing device to a desktop keyboard to avoid having to use a mouse. For many people who have become used to the touchpads built into their mobile computers, returning to a desktop computer with a conventional mouse can be uncomfortable and inconvenient. A USB touchpad requires virtually no pressure to point-and-click and arms can stay relaxed at the sides when the device is secured to the keyboard.
A USB touchpad looks like a standard touchpad with an attached cable that plugs into the USB port. The touchpad itself is a slightly rectangular pad with a touch-sensitive surface. The lightest swipe of a fingertip controls cursor movement, and taps emulate clicks. Scrolling is accomplished by sliding a fingertip up or down the vertical edge of the pad, or along the bottom edge for horizontal scrolling
