2. The optical-mechanical or optomechanical mouse consists of a ball that rolls one of two wheels inside the mouse. Each wheel contains a circle of holes or notches, allowing an LED light to shine through and be detected by a sensor. As the wheel spins these lights represent an X or Y axis for the mouse pointer on your screen. This mouse is more accurate than a mechanical mouse that uses only wheels and rollers, however, is not as good as an optical mouse. Intro 12/31/2018 2

4. •Basic construction of optomechanical mouse is same as that of the mechanical mouse. •Only different is in the sensing circuit i.e a combination of LED and photo detector is used to sense the distance travelled by the mouse. •In this mouse, there are two rollers as similar to the mechanical mouse. Each roller is connected to a wheel . There are small opening on the rim of each wheel. •As the wheel rotates a pair of LED and photo detectors detect the number of opening passed between them .

5. Features The laser of the optical mouse may bounce off certain colors and shapes on a mouse pad. There are no disadvantages to a optical mouse. The optical mouse just works better and smoother than the ball mouse, and you never have to worry about the ball getting dirty or hanging. I would suggest getting an optical mouse and throwing the ball mouse away. 12/31/2018 5
