The mice have evolved considerably over the last decade, from those using mainly a ball to track movement, current laser mice and optical sensor that work, according to their quality, fairly well on almost any surface.
This guide aims to show a number of possibilities that I consider very good in the field of mice. I try to cover various sectors of the market, from those who want to spend little but receive a good product, to those who do not care about the price of the mouse in order to obtain the one with the best features, which will generally be mice oriented to play.
Types Of Mice
Currently mice use only two types of sensors: laser and optical . In the background both types are the same (optical) but each has its own advantages and disadvantages, but it cannot be said that one is better than the other. The optical sensors use a red LED to illuminate the area generally on which must register the movement. The laser sensors , which are also optical sensors, laser lighting use infrared to detect where the mouse moves.
The movement of the mouse on the screen is based on capturing images of the surface (they are CMOS-type sensors, like those in cameras), comparing them to count the number of pixels that the mouse has moved. It is reflected by the characteristic of pixels per inch – PPP , in English DPI, and more precisely it is called CPI, counts per inch or count per inch, CPP – of the sensor, which is the resolution of the images taken. In practice, DPI indicates the number of pixels on a screen that the cursor will move when moving the mouse one inch over a surface.
Increasing the DPI of a mouse means that by moving it one inch it will be able to travel much more distance on the screen, if the conversion were 1: 1. A mouse with a 2000 DPI sensor is sufficient to move a 1920 x 1080 pixel screen from side to side in one inch (2.5 cm). Therefore, more DPI does not imply higher quality or better . It might be useful in setups with two or three 4K monitors where the mouse would have to move 6000 or 10,000 pixels to get from one end of the desktop to the other with only slight movement of the hand, but on a 1080p desktop a sensor is of little use. 16,000 PPP.
Nor can it be said that an optical sensor is better than a laser one , or vice versa. In addition to sensor DPI, quality depends on the manufacturer’s specific implementation of your mouse. The analogy in this case is the cameras of a phone, where two can use the same high-quality sensor, but one uses color filters of different types and firmware, which in practice can give different results in terms of camera. quality of the photos taken.
Laser sensors more accurately capture surface roughness, and that when processed implies noise that is added to the image processing, and may have erratic behavior on soft or fabric surfaces. In contrast, optical sensors with LED lighting capture less information from the surface and when it comes to counting movement they are better for those soft surfaces, but bad for other types of surfaces such as glass.
The acceleration referred to in many mice is intended to vary the speed of cursor movement. Positive acceleration allows the mouse to move more precisely when moving slowly, and the sensor to interpret a greater number of pixels traveled when moving quickly. If a mouse is set to a high DPI, the throttle would have to be adjusted down accordingly or it would be difficult to perform precision clicks.
In some operating systems, and specifically OS X, acceleration is done at the software level to provide greater precision with slow mouse movements. In Windows, it is left to the mouse programs and games to make these kinds of decisions —and to the users— , according to their needs.
Increasing or decreasing the speed of a mouse in operating systems involves making a linear relationship of increasing or decreasing the number of pixels that the mouse reads when scrolling. In general it is better to leave the work of deciding the acceleration to the software and operating system. Some peripheral programs also allow you to modify the sensitivity — mouse movement based on DPI, acceleration, and surface — on the x and y axes separately, or to create speed milestones with different DPI values to better suit each user.
The sensors of the mice can see their acceleration and precision in the pixel count modified depending on the surface on which it moves. The mouse electronics itself makes unintended corrections to mouse movement, allowing straight lines to be drawn in mouse movement.
The sampling rate or simply sampling ( polling ) is the rate at which samples are taken from the mouse location to send them to the PC, expressed in frequency (hertz). Since frequency is the inverse of the time it takes for something to repeat itself (period), a sampling of 1000 Hz means that samples are taken every 1 ms. The higher the sampling rate, the more reliable the mouse position calculation, while the lower the less reliable.
Changing the sampling to 125, 250, 500 and 1000 Hz are common settings, and each mouse and program will interpret these changes in different ways. Some will make more predictions about mouse movement, and others will just provide the information as is to the operating system. In general, it is standard to use 1000 Hz sampling in commercially available mice.
Button or key mechanisms
As with keyboard keys, mouse buttons also use various mechanisms to perform clicks. Depending on whether their quality is better or worse, they will have a longer or shorter useful life. There are several companies like Razer that also provide in some models mechanisms that are pressed practically without force – like the red Cherry MX mechanisms of the keyboards – which can be an advantage in certain types of games, and a disadvantage in others.
Generalist mice are usually aimed at an audience that does not necessarily want a mouse to play games, so they may be more interested simply in that it detects movement well, is wireless, or that it can be connected via Bluetooth. You can also look at their design, but in general these mice, with few exceptions, are not specifically designed for gaming.
As with any other technology product, the best products can be those that provide the best features at any price, those that provide you with the best value for money, or simply those that are cheaper and do their job without any problems.
In that last section you will find the following mice, many times sold for specific use for gaming since they may include colored LEDs, but in general what prevails in these is that they are cheap. Not everyone has 150 euros to spend on the best mice regardless of the price.
Sharkoon Skiller SGM2
The Skiller SGM2 is an inexpensive mouse, with a 6400 DPI sensor, sufficient for the vast majority of users, with configurable RGB lighting and two additional buttons on the left side. It has a right-handed design, measuring 132mm × 69mm × 42mm and weighing 106g.
Good mice that connect via Bluetooth and that can be used without problems with laptops and other devices that have this type of connection. They are oriented towards portability, so they are also usually smaller than normal so that they can be easily stored.
Corsair Harpoon RGB Wireless
This small mouse, 116.8 mm × 68.6 mm × 40.6 mm, is designed for use with laptops and to be able to take it anywhere without problems. That is why it uses Bluetooth connectivity to work, although it also has a USB adapter to work in the 2.4 GHz band with devices that do not have Bluetooth. Includes a 10,000 DPI sensor. It has two additional buttons on the left side. Its autonomy is around 60 hours without lighting using Bluetooth.
