Connection
The type of connection used by the mouse.
All types of mouse connection can be divided into
wired and
wireless. There are also
combined models that allow both methods; however, for a number of reasons, they have not received much distribution.
Wired mice can vary in connector type; however, the universal standard nowadays is USB, other options are much less common (see "Cable" for them). Anyway, such mice are much cheaper than wireless counterparts, moreover, they do not require batteries / accumulators and have an almost unlimited lifespan. On the other hand, the wire restricts mobility and can be inconvenient when connecting, especially if the computer is located far away or in a hard-to-reach place.
Wireless devices, in turn, can connect via
radio,
Bluetooth, or
Wi-Fi ; in some models, two options are combined — at the user's choice, (usually radio and Bluetooth). Regardless of the interface used, all such models are more convenient than wired ones due, in fact, to the absence of a cable; and their range is at least a few metres, so a wireless mouse can also work as a kind of remote control. At the same time, a wireless connection is more expensive than a wired connection, and besides, it requires autonomous power supply — as a result, the per
...iod of continuous operation of the mouse is limited.
As for the different types of wireless connection, here are their features:
— Radio. To connect over the air, usually, a wireless adapter is used, which is connected to the USB port of the computer. This method is convenient in that it can be used with any computer, including systems that do not have built-in Bluetooth or Wi-Fi modules. The disadvantages of this option include the fact that the adapter requires a free connector; as a result, with a small number of USB ports, difficulties can arise. However, this moment, if necessary, can be easily corrected by connecting a USB hub; so it is this connection method that is most popular among modern wireless mice.
— Bluetooth. The main advantage of this connection method is that many modern devices — laptops, most monoblock computers, smart TVs, etc. — have built-in Bluetooth modules. Thus, you can connect the mouse to such equipment directly, without occupying hardware connectors. And for PCs not equipped with internal Bluetooth modules, appropriate adapters are available (which may even be included with the mouse). In addition, some advanced models with such a connection are able to remember several Bluetooth devices at the same time and switch between them literally “with the touch of a button”. The Bluetooth communication range is at least 10 m with line of sight.
— Wi-Fi. A rather specific option, which is extremely rare — in certain models of laptop mice (see "In the direction"). In many respects it is similar to Bluetooth — in particular, it is designed mainly to work with built-in modules and allows you to use a mouse without occupying hardware connectors. At the same time, the range of communication via Wi-Fi is much greater. On the other hand, this advantage is not of fundamental importance, and on the technical side, the creation of Wi-Fi mice is associated with certain difficulties. That is why this type of connection has not received distribution.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.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.
Lighting effects
The mouse has additional lighting effects. For more information about the backlight itself, see above, and its effects can be different — ranging from a smooth change in brightness and/or colour to colour and light signals, as well as
backlight synchronization(for models with synchronization, this paragraph indicates the supported synchronization technology).
The last function is worth dwelling on separately. Synchronization itself allows you to "match" the mouse backlight with the backlight of other system components — the case, graphics card, keyboard, monitor, etc. Thanks to this matching, you can create various unusual effects: synchronous colour and brightness changes, "colour waves", "running lights" etc. However, for such work, all components of the system must support the same synchronization technology — and such a technology, usually, each manufacturer has its own. So before buying it's ok to check compatibility. However, some mice are able to work with several options at once — for example, iCUE from Corsair and MLS (Mystic Light Sync) from MSI.
Cable
Additional features of the cable that the mouse is equipped with.
These features may include a winding system,
a detachable wire, and a braided
wire(however, most modern mice still have a cable
without a braid). Here is a more detailed description of all these features.
— Retractable. Wire equipped with a special coil for winding. This feature greatly simplifies transportation: during off-hours, the wire is as compact as possible and does not get tangled, and when used, it can be unwound to the desired length (usually the coil allows this possibility). All this is especially important for laptop mice (see "In direction") — in fact, most models with a wire reel fall into this category.
— Removable. Wire that can be detached from the mouse. Almost all mice with two connection options have this feature — wired and wireless: when working in a wireless format, the cable can be removed so that it does not interfere. However, there are also purely wired devices with such a cable — mostly laptop devices, where the wire is removed for ease of transportation. Also note that most often a universal connector like microUSB is used to connect the cable, so if necessary, the wire can be replaced with another one — for example, a longer one.
— In a braid. The presence of an additional braid on the mouse cable. This feature makes the wire more d
...urable, reliable and resistant to bending. On the other hand, braid tends to accumulate dirt and fray when worn; because of this, the wire sheath loses its presentation faster than in mice without a braid. Yes, and such a wire is more expensive than a regular smooth one.Weight
The total weight of the mouse. For models with a wired connection, usually, it is indicated without cable, and for devices with weight adjustment (see above) — without weights.
This parameter is important primarily for professional gaming applications, although it is often relevant for ordinary users. Theoretically, less weight promotes speed and reduces fatigue. At the same time, in fact, much depends on the personal habits and preferences of the user: a mouse that is too light may “not be felt in the hands” and not give familiar feedback. Therefore, although most mice have a lower weight limit of
60 – 80 g, however, even among professional gaming models there are much more massive devices —
120 – 140 g or
more. The lightest variety of "rodents" is laptop (see "In the direction"), among them devices come across and
less than 60 g.
Also note that the weight to some extent depends on the size and “tricked out” of the device, but there is no unambiguous dependence here: models similar in size and functionality can differ markedly in weight.
Weight adjustment
The ability
to adjust the weight of the mouse.
This feature is relevant primarily for
gaming modelsused by professional gamers and advanced enthusiasts: for maximum accuracy of movements, it is necessary that the mouse has not only an optimal shape, but also weight. The change in weight is carried out by installing and removing special weights supplied in the kit. At the same time, in some models, by rearranging the weights in different slots, you can change not only the weight, but also the balance of the mouse, achieving the most accurate adjustment to personal preferences.
