Question

what is the difference between mechanical mouse and optical mouse​

Answer 1

$\huge\mathbb\fcolorbox{purple}{lavenderblush}{❥ศռรฬєг࿐}$

A mouse that uses light to detect movement. Introduced in the late 1990s, optical mice superseded mechanical mice because their sealed bottom surfaces do not absorb dust and dirt. They work by emitting light from an LED or laser, and a CMOS sensor detects the light reflections as the mouse is moved.

$\huge\{\fbox{\colorbox{yellow}{ANSWER}}}$

1. $\huge\bf\red{✨The mechanical mouse.}$

- The movement of the mouse is questioned by light barries. (Folie 3)

- As you can see, in the inner of the mechanical mouse there is a movable control ball, that follows the movements of the mouse.

- The part-movement is felt over two skriking surface in the horizontal axis and the vertical axis.

- The disks posses´s light and darkness sectors.

- With the help of two phototransistors per disk, it is possible to determine the revolution direction of the ball.

- Mostly, a small controller, is used. It gets a piece of information from four signals how fast and into which direction the mouse will move.

- The chip is also responsible for the serial transfer of the data.

- Lets leave that there and let´s take another example. (Part 2)

2. $\huge\bf\pink{✨The optical mouse}$

- With a pure optical mouse, the striking surface is left out and is felt the base with two sensors for each direction directly. (Folie 4)

- On the base an itself repetitive pattern is found.

- Now to the movement.

- According to the direction of the movement, the sensors have different types of pulse.

- Sensors of different colour sensitivity are usually used for the horizontal axis and the vertical axis.

- The evaluation and transfer of the signals take place in the same way with the mechanical mouse over a built in microcontroller.

- The advantage of such an optical mouse is that, it is very reliable because of its lacking mechanics

- The disadvantage is that it works only together with a particular base.

- The last point shows the trackball mouse.

- The trackball is essentially nothing else, than a mouse lying on the back.

- The sampling system is the same, as with a mechanical mouse.

- That means the trackball is frequently applied in portable computers.

- To sum up I would like to point out one or two interesting details.

- one of them

- Mechanical mice are very suspectible to dust.

- (That is a big disadvantage)

- the second is

- Optical mice are dust free and need never be cleaned

$\huge\{\fbox{\colorbox{yellow}{Conclusion}}}$

- At the end , I would like to say my favourite mice are the optical mice.

- They don´t need any care and they are better compared with the mechanical mice.
