Interface
Interface used for wired connection in mice that have this capability (see "Connection type").
The most popular nowadays is the connection through the
classic USB port. Mice for the newer
USB-C connector, for a number of reasons, are produced quite a bit, despite the advanced capabilities of this interface. And
PS/2, on the contrary, is gradually giving way to newer and more advanced standards. Here is a more detailed description of each of these options:
— USB. Connect to a traditional, full-size USB port (called USB A). Such connectors are extremely widespread: they are practically mandatory for modern PCs and laptops, and are also used as standard for working with peripherals in smart TVs, media centers and other types of electronics. That is why the vast majority of wired mice use this connector.
— USB-C. The newest (for 2020) type of USB connector; is significantly smaller than the USB A described above, as well as a convenient double-sided design. Such connectors are increasingly used in modern PCs and laptops, but very few mice are made for them; this is due to several reasons. Firstly, advanced versions of USB are often implemented through the USB-C connector, with high speed and high power supply; for mice, these characteristics are not needed, but they can be useful for more demanding devices. Secondly, the USB-C hardware socket can b
...e used for interfaces other than USB (primarily Thunderbolt v3 and v4). Thirdly, it is simply easier to get into the full-size USB A connector with a plug — especially when trying to blindly find the connector on the back of the system unit. In light of all this, only a few laptop mice are produced under USB-C (see "In the direction").
— PS/2. A specialized connector with a characteristic round shape, used exclusively for keyboards and mice; colloquially known as "pee in half". PS/2 inputs are found exclusively in desktop PCs — they are too bulky for laptops. In general, this interface is considered obsolete and less used, but it can still be found in modern computers. At the same time, PS/2 has a very practical advantage: connecting a mouse to such a socket allows you to leave an additional USB connector free, which, in turn, can be useful for other peripherals. However, mice with only such a plug nowadays are almost never found — devices that can also connect to USB have become more common (see below).
— USB or PS/2. This option most often means that the mouse itself is equipped with a USB plug, and an adapter for PS/2 is supplied with it. Thus, the device turns out to be as versatile as possible in connection; at the same time, adapters are very inexpensive, their price is almost invisible compared to the cost of the mice themselves (even inexpensive ones). Therefore, most modern manipulators with the ability to work through PS/2 belong to this category.Range
The range of the wireless connection provided in the mouse (see "Connection Type").
Almost all modern wireless models work confidently at a distance of at least 2 – 3 metres. So you need to pay attention to this parameter mainly when you plan to use the mouse at a greater distance from the computer — for example, when working with a projector at a presentation. At the same time, when evaluating the range, note that it is indicated for perfect conditions: the absence of interference and obstacles in the signal path, the full charge of the battery in the mouse, etc. In fact, the communication range may be somewhat less, so when choosing, it is worth taking a certain stock. Nevertheless, according to the claimed range, it is quite possible to evaluate the practical capabilities of different models and compare them with each other.
Type
The direction the mouse is facing. Specified only for models with additional specialization or design features — namely, for
laptop,
gaming and
vertical mice. Here are their main features:
— Laptop. Mice well suited for use with laptops. Most of these models have compact dimensions — the length of the case in them is less than 110 mm, and often less than 100 mm. This makes it easy to transport along with the laptop. And larger devices are considered laptops if such specialization is somehow indicated by the manufacturer. In addition, this category includes most models with a Bluetooth connection (see "Connection type") — such a module is found in almost any modern laptop. And wired laptop mice can be equipped with a wire winding system that allows you to adjust the length of the cable for different situations and twist it compactly for transportation.
— Game. Mice designed primarily for use in computer games and intended for gamers — including professional e-sportsmen (although the price category and capabilities of different models, of course, may vary). Such devices are often made in a characteristic "aggressive" design, with unusual patterns, logos, coloured backlighting (in some models — with effects), etc. On the functional side, gaming mice are distinguished primarily by increased sensor accuracy, as well as the presence of various specialized feat
...ures — such as additional buttons with the ability to “attach” certain game actions or even a sequence of actions to them, a triple-click (“queue”) button, a sniper button, DPI switching (see below), weight adjustment, etc. Note that narrow the specialization of such models can be different: there are both universal gaming mice and devices optimized for a specific genre (shooters, RPGs, etc.) or even a specific game.
— Ergonomic (vertical). Mice of a specific design: the surface on which the hand is placed during work is not located horizontally in such models, but with an inclination to the right (in left-handed models — to the left). As a result, the body height is noticeably greater than that of traditional models — hence the name "vertical". And the user's hand actually covers such a case from two sides: on one side (on an inclined surface) there is a palm, on the other (in a special recess) — a thumb. This position of the hand is considered more natural and comfortable than the classic horizontal position, it reduces the load on the joints and ligaments, thus reducing fatigue and the likelihood of carpal tunnel syndrome and other disorders. Vertical models are well suited for those who have to work at the computer for a long time — except that it may take some time to get used to the unusual shape after a traditional mouse.Sensor resolution
Resolution of the sensor responsible for tracking mouse movements on the work surface. Specified in DPI — dots per inch.
The physical meaning of DPI as a whole is as follows. The sensor of a modern mouse works on the same principle as the camera matrix, and consists of pixels. And DPI is the number of pixels that fall on 1 inch of the underlying surface (length or width), "visible" by the sensor.
It is believed that more DPI means a more advanced sensor and mouse in general; nowadays, models for
3500 – 5000 DPI,
12000 DPI,
16000 DPI even
more are not uncommon. In a way, it is — high resolution contributes to accuracy. However, the only thing that is directly determined by this indicator is the speed at which the cursor moves across the screen: the higher the resolution of the sensor, the greater the number of pixels that the cursor will move when the mouse itself moves a certain distance. At the same time, it is worth recalling that too high a speed is even more undesirable than too low. So the real need for high DPI (
1000 and above) arises mainly when working on large screens (4K resolution and more); for more modest displays (HD and Full HD), smaller values are often enough.
Max. acceleration
The greatest acceleration during movement, at which the mouse maintains normal performance; if this indicator is exceeded, the cursor may “break down” (moving to an unexpected place due to incorrect processing of data from the sensor).
The faster the mouse moves, the greater the acceleration acting on it. Accordingly, this parameter determines the sensitivity to sudden movements, the extent to which this model is able to normally perceive and process such movements. High values of maximum acceleration (
40 G,
50 G) are important first of all in dynamic games, especially for professional e-sportsmen and advanced enthusiasts. If the mouse is bought for relatively simple tasks (working with documents, surfing the web, etc.), you can ignore this indicator.
Max. speed
The ips (inches per second) parameter is the linear speed of mouse movement, expressed in inches per second, at which the manipulator's sensor is able to read the surface. In top models, the maximum mouse movement speed often reaches 400-600 ips, but devices with ips in the region of 200 are more common.
Number of buttons
The number of buttons provided in the design of the mouse. However, the term "buttons" can also refer to specific hardware solutions — for example, a solid touch area used in many Apple mice counts as two buttons, because. it is divided into two working areas. But the clickable wheels, as well as the power button, are not taken into account in this calculation.
The minimum number of buttons for modern mice and other similar manipulators is
two : this is the number that is necessary for comfortable work in most modern operating systems. If there are more than two keys, this means that there are additional buttons responsible for specific actions. So, even relatively inexpensive devices can be equipped with
3 – 4 buttons ; in addition to the 2 main buttons, they can have, for example, 2 side thumb keys, or 1 double/triple click button (see below). Solutions for
5 – 6 buttons are extremely popular nowadays; among them are many gaming mice, where the mentioned thumb buttons are supplemented with a double / triple click, a sniper button and/or a DPI switch (see also below about these functions). And in the most multifunctional models,
7 – 8 buttons and even
more can be installed. In some cases, this number exceeds a dozen and a half; such mice are usually gaming devices designed for RPGs and other simil
...ar genres where it is important to have a wide range of actions at your fingertips.Side buttons
The presence of the mouse side buttons — under the user's thumb.
The traditional, most popular option is two buttons, which by default are responsible for the “Back” and “Forward” commands in the browser, system file explorer, etc. There are more of these buttons in gaming mice; some of these models even have an interchangeable side panel that allows you to install a different number of side keys, as desired.
Anyway,
the side mouse buttons provide additional convenience and expand the list of features available from the device. At the same time, the buttons are always at hand, in fact, in instant access. This is especially handy in games: some frequently used actions can be tied to the side keys, such as reloading or a special attack. However, even in everyday use, it is much easier to press a button on the mouse than to move the cursor to the Back or Forward icon every time in the same browser.
Lighting
The presence of
illumination in the design of the mouse.
This illumination can be provided by the same LED that illuminates the surface below the sensor, or by separate light sources. It can have a different colour, and the most advanced systems —
RGB backlighting — allow you to adjust the shade to your liking. Anyway, the backlight gives the mouse an unusual and stylish appearance, besides, it can also have special effects (see below). However, this function has not only an aesthetic, but also quite a practical meaning: for example, a colour change can be used as a DPI level indicator (see above) or as a low battery signal. On the other hand, the backlight affects the cost of the device, and the real need for it is not so often — moreover, in many cases (for example, in the office) an extra “illumination” is completely useless. Therefore, most modern mice still do
not have a backlight.
