Wireless Keyboard With Built In Mouse

Practically every keyboard that was manufactured in the past ten years or so has utilized the USB connection. USB stands for Universal Serial Bus. The Universal Serial Bus is the descriptive standard of a universal connection between peripheral devices and a host computer. The system was invented to replace ports needing serial or parallel connections. Practically everything that can be plugged into a computer uses the USB standard connection. One of the more useful peripherals is a USB keyboard with built in mouse.

The first obvious feature of this device is the elimination of a separate mouse. That reduces some of the clutter of a busy desk. There are several varieties of a USB keyboard with built in mouse. The first type of pointing device built in to the keyboard is a trackball. The user manipulates the ball with his thumb, fingers, or the palm of his hand. There are a series of sensors under the socket that traps the ball in the keyboard. As the fingers move rotate the ball, the cursor tracks across the monitor. The one real advantage of the trackball is that the user is in touch directly with the ball, which does away with the mouse pad or the desktop.

The second type of pointing device utilized with a USB keyboard with built in mouse is the touchpad. The touchpad is a tactile sensor that has a specialized panel to pickup capacitive and conductance sensing. The human body holds an electric charge. The touchpad panel is designed to pickup or ’sense’ the movement of a human finger across its surface. The touchpad converts that sensor data into direct movement of the cursor displayed on the monitor. When the finger strokes in a certain direction, the cursor duplicates that movement. When the finger taps the touchpad, the sensors convert that into switching signals to highlight a word, or give a command. The touchpad is one of more clever and useful innovations for personal computing.
