Cable length
The length of the cable that is equipped with a mouse with the possibility of a wired connection (see "Type of connection").
When choosing this parameter, you should first of all take into account the distance from the manipulator to the connection port: a cable that is too short may simply not reach the connector, and a cable that is too long may get tangled at hand and create inconvenience. As for specific values, the most modest wire length in modern mice is
1 m or less ; such devices are intended mainly for laptops. Most desktop manipulators come with cables that
are 1.1-1.5m or
1.6-2m long, with some models running
longer than 2m.
Sensor
The model of the sensor installed in the mouse. This information is indicated mainly for models equipped with high-end sensors, which are significantly superior in their capabilities to simpler solutions. Such characteristics are important primarily for gaming mice, so most of the devices for which the sensor model is specified belong to this category.
Knowing the name, you can find detailed data on the sensor and evaluate its capabilities. Note that one of the most popular brands nowadays, under which advanced sensors are produced, is
PixArt ; on the market are often found, in particular, sensors
PixArt 3212,
PixArt 3325,
PixArt 3327,
PixArt 3335,
PixArt 3360,
PixArt 3389,
PixArt 3395. The second common brand is
Avago (recently owned by the same PixArt); the most popular model of this brand is
Avago 3050, the simplest and most affordable representative of gaming sensors.
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 similar genres where it is important to have a wide range of actions at your fingertips.Inertial wheel
A wheel with an accelerated scrolling mode that allows you to scroll through a large “sheet” of pages in text documents, spreadsheets or on Internet resources in just one movement.
The inertial wheel is a hallmark of a number of Logitech mouse models.
DPI level indicator
An indicator showing the current resolution of the mouse sensor.
The DPI value indicator is found only in models that allow you to switch the sensor resolution and are equipped with the appropriate buttons (see above). The indicator allows you to easily monitor the set DPI settings. Note that it does not necessarily show specific numbers — conventions can be used, for example, different backlight colours.
Built-in memory
The presence in the mouse of its own
built-in memory.
The main and, in fact, the only way to use such memory is to store various advanced settings (for example, the functions of programmable keys, or even entire user profiles for various games or other tasks). This feature is relevant mainly for gamers, so almost all models with this feature are gaming.
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.
