Want a great PC mouse? Understand these terms

You may think of the mouse as one of the most basic PC peripherals. And some mice may be. Point, click, and you’re done. But modern mice, especially those in the high-end, gaming, and wireless realms, have come a long way. And if you’re looking for a more advanced mouse, you may be surprised by some of the parlance going around.

Below, we’ll provide quick breakdowns of some of the most common terms you’ll see when looking for an advanced mouse. Some of this may be a refresher for you, while other phrases may be irrelevant to your needs. Some terminology may deal with performance differences that only an astute enthusiast would notice. More importantly, some of the specs detailed below will hopefully provide you the kind of information needed to justify spending $50-plus (or even $150-plus) for a mouse.

Optical sensor

High-end mice these days aren’t relying on trackballs anymore. Instead, they’re largely using optical sensors, leveraging a camera, LED, complementary metal oxide semiconductor (CMOS) image sensor (like in a camera), and digital signal processor (DSP) to convert your arm movements into pointer movements. The DSP, as explained by How Stuff Works, “is able to detect patterns in the images and see how those patterns have moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer.” A bit less common in terms of new releases of late (but still advanced) are laser sensors, like Logitech’s Darkfield sensor used in Logitech MX Master 3.

What do these technologies mean for you though? For one, they’re supposed to bring improved tracking performance over trackballs. And while dust may accumulate in the sensor area, they won’t attract nearly as much crud as trackballs, which roll across dirty surfaces and have gaps around their circumference. And with fewer moving parts, you can hope for less rapid wear and tear, too.

An optical or laser sensor also means you don’t need a mousepad for the mouse to work well. Mice makers, like those behind the MX Master 3, sometimes brag about this as if it were an exclusive feature. But even a cheaper optical or laser mouse (this $20 Microsoft mouse we just pulled out of a dusty closet, for example) should work sans mousepad. However, some mice may track better than others in these conditions.

Just because you can use a mouse without a mousepad doesn’t mean you’ll actually want to. Skipping a mousepad can make movements feel and sound scratchy, especially if the mouse lacks feet on its underside to help it glide more smoothly. And working on some surfaces feels better than other. For example, a glass desk can offer less friction than a wooden desk.

Both optical and laser sensors come from various brands and model numbers. Again, we’re seeing more mice opt for optical these days, and some brands, including Logitech and Razer, make their own. PixArt, meanwhile, is the most common third-party brand for optical sensors.

But not all advanced mouse sensors are made equal. If you’re going to invest money in good PC mouse, it’s a good idea to check out the sensor’s performance specs.

DPI or CPI

Dots per inch (DPI) and counts per inch (CPI) are used interchangeably around the mouse world. What’s the difference? Basically, DPI came from the print world and is taken from the display’s perspective, while CPI comes from the mouse sensor’s perspective. Either way, the acronyms are indicative of the mouse’s sensitivity, or how many pixels your pointer will move when you physically move the mouse.

When using a mouse with a low DPI or PCI setting, the cursor will move move very slowly across the screen. A mouse with a high CPI setting will move much more rapidly across the screen with the same movement. Without getting too technical, for every inch a mouse with 1,000 CPI moves, your cursor will (generally) move 1,000 pixels. (That’s according to PC gaming peripherals maker SteelSeries.) Many high-end mice let you specify the mouse’s CPI. Their software may let you use a slider or enter a specific number or numbers. Some mice also have a dedicated button, called a CPI or DPI switch, for toggling across saved CPI or DPI settings. And there are some gaming mice with a sniper button, or a button that instantly drops the mouse’s CPI when held down, in order to hone in on a target, like in a first-person shooter.
