Optical
Optical mice use the same basic principle as opto-mechanical mice,
but they use different methods. Optical mice look the same as other mice,
but do not use a "ball". The optical mouse functions by measuring the patterns
of laser beams reflected from a mouse pad. In theory, the mouse calculates
the changes using horizontal and vertical sensors. One major drawback of
the optical mouse is its requirement for a special mouse pad. This means
the days of your favorite cartoon character would be short-ended on an
optical mouse pad. The optical mouse pad contains a grid-work of lines
that reflect the laser in different ways to simulate motion.
