Presentation
(Differences between mechanical mice and optical mice)
Introduction
- Good morning.
- My name is Thomas and I am a student.
- I would like to talk today about the differences between the mechanical mice and the optical mice. (Folie 1)
- Let me start by saying just a few words about the presentation
Parts
- I have divided my presentation into three parts.
Outline
- Lets start with the movement.
- The control of a programme can essentially be simplified with a mouse. (Folie 2)
- The keyboard usally only serves the data capture.
- As you can see, it is better to use a mouse.
- This is a faster possibility than a keyboard.
- It demonstrates the first example. (Part 1)
1. 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. 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
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.

Frequently asked questions
What is the presentation about?
The presentation is about the differences between mechanical and optical mice.
What are the main parts of the presentation?
The presentation is divided into three parts, covering the movement, mechanical mouse, and optical mouse.
How does a mechanical mouse work?
A mechanical mouse uses a movable control ball to track movement. The movement is detected by light barriers and phototransistors.
How does an optical mouse work?
An optical mouse uses sensors to detect movement on a patterned surface. It uses sensors of different color sensitivity for the horizontal and vertical axes.
What is the advantage of an optical mouse?
Optical mice are more reliable due to their lack of mechanical parts.
What is the disadvantage of an optical mouse?
Optical mice typically require a particular base to work correctly.
What is a trackball mouse?
A trackball mouse is essentially a mouse lying on its back, using a ball for input. The sampling system is the same as a mechanical mouse.
What are the disadvantages of mechanical mice?
Mechanical mice are susceptible to dust.
What are the advantages of optical mice?
Optical mice are dust-free and do not need to be cleaned.
What is the presenter's preferred type of mouse?
The presenter prefers optical mice because they require less maintenance and are considered better than mechanical mice.
