A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface.
Logitech LS1 laser mouse, with a sleek glossy finish and stylish color accent, adds a little elegance to just about any workspace. The high-performance laser sensor delivers smoother cursor control on virtually any surface, and the smooth shape and soft side grips offer enhanced comfort for either hand.
The trackball mouse is a perfect fit for computer users with a disability. The versatility of the trackball mouse allows those with limited movement an alternative to the typical off-the-shelf mouse. Users do not slide the mouse around a mouse pad; they only use their fingers to roll the ball to move the mouse pointer.
Your keyboard and mouse work by sending wireless signals to a USB receiver that came with your setup. This might be a small hub that plugs into a USB port with a wire, a small dongle similar in size and shape to a thumb drive, or a very tiny unit that is barely visible once you slide it into a USB port.
