Computer mouse with a ball. The best optical LED computer mice. Facts about the inventor
Today I want to tell you, my dear readers, how I chose a computer mouse for my beloved wife. I hope my train of thought will be interesting to you, and everything that I learned about these “rodents” during my research is useful.
So, computer mouse- what they are, how they differ and which one is better to choose. As always - in detail and in human language...
I'll start with the interface, or more simply put, the way to connect the mouse to the computer...
Wired or wireless mouse?
Here it is very important to decide for what purpose the mouse is chosen and how it will be used. If you like to play computer games (drive cars, shoot, run in the jungle...) and will do this every day, buy a wired mouse.
During dynamic scenes in a wireless controller, the cursor may slow down (radio signal reflections, various interferences...), which will make you very nervous. And in games you need to work the mouse very intensively, which will greatly affect the energy consumption of batteries or accumulators - you will get tired of changing (buying) or charging them.
If you are not interested in games and prefer quiet surfing on the Internet or just working in office applications, then your choice is definitely a wireless computer mouse! This interface is much more convenient, mobile and comfortable than a wired one. The very feeling of “non-attachment” is worth it. You can also use it as a remote control when watching a movie or photos (lying on the sofa). Say no to unnecessary wires in the workplace.
Let's summarize the first result. A wired mouse is faster and more trouble-free in games, and also does not require maintenance (replacing batteries or charging batteries) and further investments (buying batteries or accumulators). A wireless mouse is convenient for its portability and practicality.
In terms of price, these two interfaces are practically the same today - you can find a wireless or wired mouse for $10, or even for $200.
In turn, wireless mice are divided by connection type - radio frequency, infrared, induction, Bluetooth and Wi-Fi. The most optimal in terms of price, practicality and quality is radio frequency.
My wife doesn’t play Crisis or Stalker; we have an excellent charger and two sets of batteries at home, so I chose a wireless interface for her future mouse.
Optical or laser?
These two technologies are very often confused or even combined, but in vain. An optical mouse is a manipulator equipped with a very small video camera that takes approximately a thousand photographs per second, they are processed by the processor and sent to the computer. This mouse uses a light diode that produces a beam of light in the visible range. These mice are also called LED mice.
Optical mice work worse on glossy or mirrored surfaces, and they are also less sensitive to movement, but more on that below. The optical sensor technology is older and less expensive.
A laser mouse is designed similarly, the only difference being the use of a semiconductor laser instead of a diode. When working with a laser mouse, there is no visible glow from the sensor, it has no visible backlight...
Laser mice have a higher sensor resolution and, accordingly, more accurate cursor movement (players, this is your choice). In the case of using a wireless mouse, laser mice are more energy efficient (they work noticeably longer without replacing batteries).
Computer mouse resolution
The higher the resolution, the more sensitive the mouse is to movement. Less movement on the table means more movement on the screen. The maximum resolution of an optical mouse today is 1800 dpi, and for a laser mouse the maximum resolution is 5700 dpi.
Why do you need high mouse resolution? For computer games. High DPI makes it possible to aim with high accuracy, turn faster and make precise jumps. Draw your conclusions, gamers.
At the same time, in order for a computer mouse not to cause delays and difficulties in control, 800 dpi is enough (this is exactly the indicator for ball mice). In most modern mice this parameter can be switched.
Mouse resolution is often confused with the mouse sensitivity setting in the operating system toolbar. In the mouse settings through the control panel, you artificially change the scale of the surface under the sensor, and the mouse resolution is a real, physical value.
Mouse shape and design
Once upon a time I read about the special shape and coating of the handles of weapons, which are given upon request to bandits who have taken hostages. So, they are made uncomfortable, causing inconvenience, due to which the reaction of criminals slows down to two seconds!
What I mean is that you should not neglect the design of the mouse, the build quality and the materials used to cover it. It is very advisable to touch the mouse before purchasing - you will immediately feel your mouse, I assure you.
Additional criteria for choosing a computer mouse
Often, high-quality, branded mice can be adjusted in weight by selecting weights inside the case - some people like light mice, while others like heavy ones. I personally like the latter.
More recently, a new type of computer mouse has appeared - touch...
Their working surface is touch-sensitive and completely smooth (no wheel or buttons). Such mice understand certain gestures with which you can scroll through photos in the graphics viewer or surf in the browser (back and forth across pages). You can also assign any action in the system or program to a specific gesture.
Annotation: A mouse is one of the required components of the basic configuration of any desktop computer. A touchpad (touchpad) can act as a kind of mouse substitute in laptops. With its help, you control the cursor by moving your finger along the surface of this device. But a laptop touchpad cannot compete with a computer mouse in ease of use. Using a mouse, you can control a special pointer (cursor) displayed on the screen of a personal computer (PC). There are several types of modern mice, differing both in the method of connection to the computer (wired and wireless) and in the principle of operation (optical and laser).
Optical computer mice have a light emitter and a light receiver, thanks to which the movement of the manipulator along the surface is recorded. In other words, optical mice use a tiny camera and a light source (LED). A beam of light is reflected from the surface on which the mouse is moving and analyzed. Optical mice are the most popular among casual PC users today, but they have problems when working with highly reflective (white, glass or metal) surfaces (Figure 4.1).

Mice can be wired or wireless. A wired mouse, like a keyboard, is connected to a PS/2 or USB connector. USB connection provides higher transmission speed data compared to using PS/2, which should be considered when purchasing a gaming computer mouse. The wireless mouse transmitter also plugs into one of these connectors, after which you can work with the mouse without experiencing the discomfort of a wire that takes up space on the table and can constantly cling to something. This wireless mouse is powered by a built-in battery or by AA batteries.
Laser mouse
This mouse will be more expensive than an optical mouse (about $100) because it uses a laser beam instead of an LED. This mouse works significantly more accurately and smoothly than optical ones, and on any surface. The laser allows you to increase the accuracy of the mouse to 2000 dpi. The mouse is good for computer game fans and designers. As an illustration of what has been said in Fig. Figure 4.2 shows the Logitech V450 Nano wireless mouse. The red arrow in the figure shows its receiver, which is plugged into the USB port of the PC. The mouse operates at a frequency of 2.4 GHz, its battery ensures operation of the mouse for a year.

How to choose the right computer mouse?
So, mice are different. But which mouse should you buy? Buy a mouse in accordance with its intended use, i.e. the work you will do on your PC. The size and shape of the mouse should fit the size of the palm of your hand, as these characteristics are responsible for comfort and rational distribution of the load on the hand. Among the well-known and popular manufacturers of computer mice are Logitech and Genius. Next, we will look at the main parameters that you should consider when buying a mouse.
Permission
Optical mice are considered standard today and are suitable for most of your everyday tasks. Buying a laser mouse will interest you if you are looking for a manipulator with special characteristics. Sensitivity The (resolution) of a mouse is determined by its sensor characteristics, which are measured in dots per square inch (dpi). A standard mouse has a resolution of 400–600 dpi and a polling rate of 100 Hz - these parameters of the manipulator meet the needs of most PC users. You will need a computer mouse with a resolution of over 1000 dpi to work with graphics and engineering applications (for example, Adobe Photoshop or AutoCAD). High resolution provides greater accuracy of cursor positioning.
New term
Under resolution mice understand the number of measurements the mouse makes over the distance traveled. It is expressed as the number of measurements per unit length of 1 inch (2.54 cm).
Response time
Response time a computer mouse characterizes the polling frequency and processing time of the light signal, which is of great importance for computer games. The response time for gaming mice should be more than 1000 Hz. However, keep in mind that the higher this setting, the faster the mouse responds and the more difficult it becomes to control.
Advice
Since it is necessary to maintain a balance between mouse speed and cursor positioning accuracy for a given monitor screen resolution, today a mouse resolution of 800 dpi when working on a monitor with a resolution of 1280x1024 can be called a reasonable compromise. Raising the resolution above 800–1000 dpi does not make sense, since the mouse will be inconvenient to use.
Additional functionality
Computer mouse options can be expanded with additional keys and modifications to the scroll wheel. The wheel can simply scroll the document up or down, or it can also be push-button, i.e., it can also serve as an additional button. An additional button in graphics programs can, for example, change the image viewing scale, which is convenient when working with graphics. Mice for computer games are equipped with a special computer program that allows you to change their capabilities. For example, you can change their sensitivity, and replacing the scroll wheel with a trackball allows you to position the cursor more accurately. This computer mouse is perfect for working with computer graphics. As you already understand, computer game lovers place the highest demands on mice. In addition to the requirements already noted above, they are even selected by weight. Although there are piece products that are more sophisticated. For example, if you do not want anyone other than you to use the computer, then you can purchase a mouse with a built-in sensor that reads your fingerprint.
Techniques for controlling the cursor with a mouse
Below we will look at the basic techniques for using the mouse in the Windows 7 operating system.
Exercise 4.1. Mouse hangs
Hover your mouse over the button Start located on Taskbars, and hold the mouse for a while. The Start text pop-up appears (
Friends, according to statistics, most people believe that all computer mice are the same, but this is not true! You have no idea how important it is in our computer business choose the right mouse, even if you spend only a couple of hours a day at the computer.
A computer mouse is, in fact, an extension of the user’s hand, its interface for convenient computer control. When working with a computer, the user should ideally forget about the mouse and fully concentrate on what is happening on the monitor screen, and if the mouse does not suit a given person according to various parameters stated by me later in the article, the person simply will not be able to concentrate as much as possible on his task and, most importantly, he will not even immediately He will understand what is bothering him. Moreover, due to working with an unsuitable mouse, you may develop paresthesia of the hand - numbness and periodic severe pain in the hand resulting from prolonged work or even simply being in an uncomfortable and unusual position for the hand.
Sometimes watch your colleagues; if, while working at the computer, one of them periodically massages his right hand or occasionally shakes his right hand, then come up and advise him to change the mouse. But of course, a lot still depends on the computer desk and keyboard, we will also talk about this in our articles.
Friends, you need to choose everything correctly: a computer chair, a table, a monitor, a mouse, a keyboard and everything else, even the case of the system unit needs to be chosen correctly so as not to constantly crawl under the table to connect USB flash drives.
Professionals do not buy a mouse on the principle of “come and take the first one you come across,” since choosing the wrong mouse can cause physical discomfort while working with a computer.
Low mouse sensitivity (measured in dpi) will make your work in graphic editors uncomfortable, and a low polling frequency (response) will “let you down” in computer games, excessively loud key clicks can begin to irritate over time, by the way, the same applies to the keyboard .
How to choose a computer mouse?
Let's look below at what types of computer mice there are, and also give some tips on how to choose the ideal computer mouse for yourself.
Computer mouse - history and today's realities
But first, some historical facts. The computer mouse was invented by Douglas Engelbart in 1963 as a device for NASA's space project. The first mouse consisted of two perpendicular wheels and a body. Only 10 years later the mouse was introduced into the design of a personal computer and became more widespread.
And its departure from the scene is not yet planned - neither touchpads, nor touch screens, nor any other devices for entering commands to computer devices are yet capable of offering greater ease of use, greater accuracy of commands that even the most ordinary computer mouse has.
There is a huge variety of computer mice on the market today. How are they different from each other?
1. Mouse sensor type
Optical and laser– these are two types of computer mice, differing in the type of sensor, which can be seen on the shelves of retail outlets with computer products and on the Internet.
About 10 years ago you could still find a ball mouse; users with decent experience working with PCs probably remember it.
I can’t forget it thanks to the huge disadvantage of this mouse - it’s a ball located at the bottom of the mouse body. Thanks to this ball, the mouse could move smoothly across the surface, but this ball constantly became dirty. It needed to be cleaned at least once a week so that the mouse could be used comfortably and would not slow down while moving it. The ball mouse was heavy, and could not move on any hard surface, so you always had to buy a special mat along with the ball mouse. Nowadays, a ball mouse can only be purchased as part of the assembly kit of some old PC as an add-on.
Optical mouse- the most common today, not least due to its affordable price.
Compact wired optical mouse Oklick 404 USB, has a rubberized scroll wheel and buttons with indentations for fingers. The mouse compares favorably with others due to its ergonomic shape. Rubberized side surfaces securely hold the mouse in your hand during normal work and games.
In most cases, an optical mouse does not need a mouse pad; problems with movement may occur only on metal or glass surfaces. The operating principle of an optical mouse is determined by a tiny camera built inside. This camera, when moving across the table surface, takes thousands of pictures every second, thanks to which the user sees a moving cursor on the monitor screen. The optical mouse is lightweight and requires virtually no cleaning.
Laser mouse It works using a semiconductor laser, which determines its movements to display the cursor on the monitor screen. The laser mouse works on any surface, even on your hand or knee. Another advantage is that a laser mouse is more accurate and faster than an optical mouse. But, naturally, it costs more than optical.
Laser gaming mouse A4Tech XL-747H. Very ergonomic and comfortable, fits nicely and securely in the hand. I use it personally, I looked for it for a long time without any spiders, but I didn’t find it, I had to come to terms with it. Like the previous one, it has buttons with indentations for fingers and rubberized side surfaces.
Why did I buy this mouse? Because it is ideal for large hands, if you have a small hand, select the mouse according to your size. Also pay attention to the two side buttons, they may also be useful to you; there is also a double-click button on the front side.
This mouse has very high sensitivity or resolution which is very important!
Mouse sensitivity directly depends on the resolution of the sensor, measured in dots per inch (dpi). If the mouse has a resolution of 1000 dpi, then it is very convenient to work with it in graphic editors, such programs as Photoshop. This mouse has a resolution of 3600 dpi.
The mouse polling frequency is important in games, you need at least 1000 Hz, our mouse has exactly this resolution.

Notice how it sits in my hand. The hand rests completely on the mouse. The index and middle fingers end where the mouse ends. The arrows indicate two side buttons.
There is a very convenient double-click button that your index finger can easily reach.
But what will happen if I use a small mouse for myself. You see, my hand has acquired an unnatural position. I have to keep my index and middle fingers constantly tense, so my hand gets tired quickly.
If I rest my hand completely on the mouse, it immediately becomes clear that the mouse is clearly not the right size for me.
2. Buttons and mouse wheel
Two mouse buttons and a wheel for vertical scrolling are a standard that should be present in any model, even the most inexpensive one. Some mouse models have a third button (usually next to the wheel) - it produces a double click. It’s a kind of innovation for the lazy, but personally I use it often.
A little more expensive than regular mice are more functional computer mice with additional buttons - for example, the Windows button, buttons for opening mail, favorites, search, etc. For the convenience of web surfing and working with large documents, the mouse can be equipped with a special wheel, which by inertia can rotate for up to 7 seconds, so that you can quickly scroll through dozens of pages of documents or extremely long web pages.
Special gaming mice are equipped with additional side buttons, to which gamers can assign individual actions in the game. Gaming mice can also have a second wheel, usually for horizontal scrolling.
3. Mouse connection interface
PS/2- This is a standard computer port specifically designed for connecting a mouse. It is better to connect the mouse through this port to older computers that do not detect USB ports before Windows loads. Otherwise, problems may occur during system reinstallation.
USB– you can safely connect a mouse through this computer port if your computer in BIOS mode detects connected USB devices.
You won’t find a special selection of mice connected via the PS/2 port at points of sale of computer equipment. The reason for this is that store owners try to purchase goods designed for the largest possible consumer audience. So, laptops do not have a PS/2 port, but via USB the mouse can be connected to a PC, a laptop, and even a tablet or smartphone (via a mini-USB adapter).
Both PS/2 and USB– these are wired connections of the mouse to the computer.
Bluetooth and radio interface are the most common wireless interfaces for connecting a mouse to computer and mobile devices.
Bluetooth – almost all laptops, tablets and smartphones are equipped with this module today. It is through the Bluetooth module that the battery-powered mouse connects to various computer and mobile devices. The advantage of this type of wireless connection is its versatility. But there is also a huge drawback - when a laptop, tablet or smartphone is running autonomously, the Bluetooth mouse will quickly exhaust its battery life. As for the PC, it is obvious that for the sake of this interface there is no point in specially equipping the assembly with a Bluetooth module if it is not needed otherwise.
It is much easier for a PC to purchase a wireless mouse with a radio interface, and such mice are slightly cheaper than Bluetooth mice.
The radio interface provides for connecting a mouse and a computer using a small receiver that is built into the USB port of a computer or laptop. The mouse already contains a radio receiver inside itself. There should be no problems connecting a radio mouse - as a rule, Windows automatically selects and installs drivers for the radio receiver.
How to choose the ideal computer mouse for yourself?
Of course, the choice of a computer mouse should be determined by its intended purpose - that is, matched to the tasks that you mainly perform on the computer. The second criterion for choosing a mouse is the specific computer device (PC, laptop, tablet).
When choosing a mouse, place your hand on it and make a few movements. You should not feel any discomfort, the mouse should lie comfortably in your hand. Press the buttons to appreciate the sound of the mouse click; it should not irritate you. Feel the surface of the mouse - if its surface is not rough, it will most likely slip out of your hands.
For home and office computer use - working with programs, web surfing, playing multimedia content - you will only need a regular optical mouse. In this case, the emphasis should be on its ergonomics. No more. If you want to speed up the process of working with mail or searching for information, you can pay for additional functional buttons.
For working with a laptop or tablet, a small wireless mouse, preferably a laser one, is more suitable. This will ensure comfortable work with a portable device on any surface, in any “mobile” pose.
For computer games, the most ideal option is a large laser mouse. Such a tool will allow you to perform this or that trick with maximum efficiency - a jump, somersault, shot, etc. - at the most crucial moment. Since during computer games the mouse is exposed to a large number of mechanical influences (and this is not counting the nerves that give way during a loss), it is better to choose a model with a special durable coating. Do you need the above-mentioned additional buttons on the side panel of a gaming mouse? You must decide this question taking into account the specifics of the games you play. If you need them, you should definitely test the ease of working with them.
And, finally, clarify the specifics of the mouse connection interface. Find out from the seller how long the battery life of your laptop or tablet will be taken away from connecting a wireless mouse, so that you can turn it off in time if you do not have the opportunity to recharge your laptop or tablet.
If your computer does not detect USB ports before loading the operating system, when buying a USB mouse, make sure that even the most shabby, nevertheless working mouse with a PS/2 connector is lying in the house in the right place. It may be useful for resuscitating or reinstalling Windows.
Hello, dear readers of the blog site. There are a huge number of computer mice or mice, as they are called differently. According to their functional purpose, they can be divided into classes: some are intended for games, others for regular work, and others for drawing in graphic editors. In this article I will try to talk about the types and design of computer mice.
But first, I propose to go back a few decades, just at the time when this complex device was invented. The first computer mouse appeared back in 1968, and it was invented by an American scientist named Douglas Engelbart. The mouse was developed by the American Space Research Agency (NASA), which gave a patent for the invention to Douglas, but at one point lost all interest in the development. Why - read on.
The world's first mouse was a heavy wooden box with a wire, which, in addition to its weight, was also extremely inconvenient to use. For obvious reasons, they decided to call it “mouse”, and a little later they artificially came up with a decoding of this abbreviation. Yeah, now mouse is nothing more than a "Manually Operated User Signal Encoder", that is, a device with which the user can manually encode a signal.
Without exception, all computer mice include a number of components: a case, a printed circuit board with contacts, microphones (buttons), a scroll wheel(s) - all of them are present in one form or another in any modern mouse. But you are probably tormented by the question - what then distinguishes them from each other (besides the fact that there are gaming, non-gaming, office, etc.), why they came up with so many different types, look for yourself:
- Mechanical
- Optical
- Laser
- Trackball mice
- Induction
- Gyroscopic
The fact is that each of the above types of computer mice appeared at different times and uses different laws of physics. Accordingly, each of them has its own disadvantages and advantages, which will certainly be discussed further in the text. It should be noted that only the first three types will be considered in more detail, the rest - not in so much detail, due to the fact that they are less popular.
Mechanical mice are traditional ball models, relatively large in size, requiring constant cleaning of the ball to work effectively. Dirt and small particles may become trapped between the rotating ball and the housing and will need to be cleaned. It won't work without the mat. About 15 years ago it was the only one in the world. I will write about it in the past tense, because it is already a rarity.
At the bottom of the mechanical mouse there was a hole that was covered by a rotating plastic ring. There was a heavy ball underneath it. This ball was made of metal and covered with rubber. Under the ball there were two plastic rollers and a roller, which pressed the ball against the rollers. When the mouse moved, the ball rotated the roller. Up or down - one roller rotated, right or left - the other. Since gravity played a crucial role in such models, such a device did not work in zero gravity, so NASA abandoned it.
If the movement was complex, both rollers rotated. At the end of each plastic roller an impeller was installed, like on a mill, only many times smaller. On one side of the impeller there was a light source (LED), on the other there was a photocell. When you move the mouse, the impeller rotates, the photocell reads the number of light pulses that hit it, and then transmits this information to the computer.
Since the impeller had many blades, the movement of the pointer on the screen was perceived as smooth. Optical-mechanical mice (they are simply “mechanical”) suffered from great inconvenience; the fact is that they periodically had to be disassembled and cleaned. During operation, the ball dragged all sorts of debris inside the case; often the rubber surface of the ball became so dirty that the movement rollers simply slipped and the mouse malfunctioned.
For the same reason, such a mouse simply needed a mouse pad to work correctly, otherwise the ball would slip and get dirty faster.
Optical and laser mice
There is no need to disassemble or clean anything in optical mice., since they do not have a rotating ball, they work on a different principle. An optical mouse uses an LED sensor. Such a mouse works like a small camera that scans the surface of the table and “photographs” it; the camera manages to take about a thousand such photos per second, and some models even more.
The data from these images is processed by a special microprocessor on the mouse itself and sends a signal to the computer. The advantages are obvious - such a mouse does not need a mouse pad, it is light in weight and can scan almost any surface. Almost? Yes, everything except glass and mirror surfaces, as well as velvet (velvet absorbs light very strongly).
A laser mouse is very similar to an optical mouse, but its operating principle differs in that Laser is used instead of LED. This is a more advanced model of an optical mouse; it requires much less energy to operate, and the accuracy of reading data from the working surface is much higher than that of an optical mouse. So it can even work on glass and mirror surfaces.
In fact, a laser mouse is a type of optical mouse, since in both cases an LED is used, it’s just that in the second case it emits invisible spectrum.
So, the operating principle of an optical mouse differs from that of a ball mouse. .
The process begins with a laser or optical (in the case of an optical mouse) diode. The diode emits invisible light, the lens focuses it to a point equal in thickness to a human hair, the beam is reflected from the surface, then the sensor catches this light. The sensor is so precise that it can detect even small surface irregularities.
The secret is that namely the unevenness allow the mouse to notice even the slightest movements. The pictures taken by the camera are compared, the microprocessor compares each subsequent picture with the previous one. If the mouse moves, the difference between the pictures will be noted.
By analyzing these differences, the mouse determines the direction and speed of any movement. If the difference between the pictures is significant, the cursor moves quickly. But even when stationary, the mouse continues to take pictures.
Trackball mice
Trackball mouse is a device that uses a convex ball - "Trackball". The trackball device is very similar to the device of a mechanical mouse, only the ball in it is located on top or on the side. The ball can be rotated, but the device itself remains in place. The ball causes a pair of rollers to rotate. New trackballs use optical motion sensors.
Not everyone may need a device called “Trackball”; in addition, its cost cannot be called low; it seems that the minimum starts from 1,400 rubles.
Induction mice
Induction models use a special mat that works like a graphics tablet. Induction mice have good accuracy and do not need to be oriented correctly. An induction mouse can be wireless or inductively powered, in which case it does not require a battery like a regular wireless mouse.
I have no idea who might need such devices, which are expensive and difficult to find on the open market. And why, who knows? Maybe there are some advantages compared to ordinary "rodents"?
Gyroscopic mice
Well, we have quietly approached the final type of computer mice- gyroscopic mice. Gyroscopic mice use a gyroscope to recognize movement not only on the surface, but also in space. You can take it from the table and control the movements with your hand. The gyroscopic mouse can be used as a pointer on a large screen. However, if you put it on the table, it will work like a regular optical one.
But this type of mouse can really be useful and popular in certain situations. For example, at some presentation it will be very useful.
And finally: For normal operation of the mouse, it is very important that the surface on which it moves is level. Usually, special mats are used for this. An optical mouse is more demanding on the surface; you can use it without a mousepad, but it will glitch on surfaces with potholes or on glass. A laser mouse can work even on your knee or on a mirror.
I think this article helped you better understand the design of a computer mouse, as well as find out what types of computer mice there are.
Types of computer mice. There are all sorts of computer mice. Such diversity can even make your head spin. But just recently there was practically no choice. It would seem, what else can you come up with? But it turns out it is possible. Each company that produces these small and so necessary “animals” finds more and more new designs and functions for them.
Which There are types of computer mice?
There are just not that many species. Here they are:
- Mechanical or ball (almost no longer used);
- Optical;
- Laser;
- Trackball mice.
- Induction;
- Gyroscopic.
Mechanical or ball mice
Mechanical or ball mice can only be found among collectors. Although just seven years ago it was the only species. It was not very comfortable to work with it, but not having any other types, we thought it was a super mouse.
She was a little heavy in weight and didn’t want to work without a mat. And her positioning left much to be desired. This was especially noticeable in graphics programs and games. And I had to clean it very often. What didn't fit under this ball? And if there were still animals living at home, then this process was repeated at least once a week.
I always had tweezers near my computer, because... my furry friends always tried to sleep near the computer, and their fluff clung to the rug, making it shaggy. Now I no longer have such a problem. The ball-shaped “rodent” was replaced by a more modern mouse – an optical one.
Optical LED mouse
Optical LED mouse - it works on a different principle. It uses an LED and a sensor. It already works like a small camera that scans the surface of the table with its LED and photographs it. An optical mouse can take about a thousand such photos per second, and some types even more.
The data from these images is processed by a special microprocessor and sends a signal to the computer. The advantages of such a mouse are obvious. It doesn't require a mat, is very light in weight and can easily scan almost any surface.
Optical laser mouse
Optical laser mouse - very similar to optical, but its operating principle differs in that instead of a camera with an LED, a laser is already used. That’s why it’s called laser.
This is a more advanced model of an optical mouse. It requires much less energy. The accuracy of reading data from the working surface is much higher than that of an optical mouse. It can even work on glass and mirror surfaces.
Trackball mouse
Trackball mouse – a device that uses a convex ball (trackball). The trackball is an inverted ball mouse. The ball is on top or side. It can be rotated with your palm or fingers, and the device itself remains in place. The ball causes a pair of rollers to rotate. New trackballs use optical motion sensors.
Induction mice
Induction mice – use a special mat that works like a graphics tablet.
Gyroscopic mice
Gyroscopic mice – using a gyroscope, it recognizes movement not only on the surface, but also in space. You can take it from the table and control the movement of the brush in the air.
These types of computer mice still exist in our markets.
Nowadays there is a very wide variety of such devices. Some designs deserve special attention. And I will describe them. Follow site updates.
