Different types of computer mouses

Computer mice some in a number of varieties. You can find a computer mouse for just about any use. To figure out what kind of mouse would work best with your PC, you need to know your mouse options:

3. Mechanical Mouse
It contains a metal or rubber ball on its under side. When
the ball is rolled in any direction, sensors inside the mouse detect
this motion and move the on-screen mouse pointer in the same
direction

5. 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, 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.

mouse.
1.moving the mouse turns the ball.
2.X and Y rollers grip the ball and
transfer movement
3.Optical encoding disks include
light holes.
4.Infrared LEDs shine through the
disks.
5.Sensors gather light pulses to
convert to X and Y vectors.

7. An optical computer mouse uses a light source, typically
an LED, and a light detector, such as an array of photodiodes, to
detect movement relative to a surface.
It is an alternative to the mechanical mouse, which uses
moving parts to sense motion.

9. Laser Mouse
A laser mouse is a type of optical mouse that uses laser light to detect
mouse movement. Like all optical mouse, the laser mouse has no moving
parts inside. Laser is more accurate than the standard optical mouse design,
providing for up to 20x greater sensitivity and precision. This improved
sensitivity and precision can be key for gaming applications and graphical or
engineering design applications, where pinpoint accuracy is important.
Laser mouse have a higher dpi, which means that they can track more dots
per inch, which in turn means that they're more sensitive.

11. Optical Mouse
•Less expensive
•LED lights used in tracking
movement
•Lower resolution (3000 dpi)
•Preferred surfaces include mouse
pads, non-glossy surfaces
Laser Mouse
•More expensive
•Laser diode used in tracking
movement
•Higher resolution (6000 dpi)
•No preferred surfaces or mouse
pad required
