We all have been using mouse, computer one not a rat. Basically in older days, we used to have a ball beneath it which helps tracking the motion of the mouse. But nowadays everything has advanced and we started using a different technology, which is more accurate and easy to use too. Optical Mice have a light(usually red in color) and a camera which clicks thousands of photos per second and send to computer,then computer analyses them and the cursor on screen starts moving. Laser Mice also have the same working just they use infrared light, instead on a red LED.
So, let’s keep moving and learn about some of the basic terms regarding mouse. These aren’t important to normal users but a hell lot to gamers, designers and few other whom I don’t know.
Wait! Wait! Don’t you leave
Grab the knowledge buddy
We are going to talk about DPI and Pooling Rates below:
1)DPI(Dots Per Inch):
DPI can be related to the sensitivity of the mouse. Like for example, you have two mouse one with higher DPI and other with lower DPI. If we imagine that we did the same movement to both the mouse, the cursor will move more in the case of higher one. Higher DPI mouse is more sensitive to the movements than the lower one.
A too high DPI will cause a lot of issues to use, you do a flick and the cursor sails from one part to another part of the screen, which you never wanted, similarly, a too low is also not what we want. It will be like we need to make the mouse crawl all over the mouse pad to make it to the other end of the screen.
Thinking from a Gamer’s perspective, DPI is a lot important and you will also understand that soon. Assume you are playing First-person shooter game like CS:GO(Counter Strike: Global Offensive) and you have a Sniper Rifle with you. In the zoomed in state, in order to do hit the target, a higher DPI will help you as it will be more sensitive to movements so you will be able to aim more precisely. If you are with a normal gun, you never want to go far away from the target by just a slight movement of the mouse. So a lower DPI is preferred here. Nowadays, gaming mouse has a switch to adjust DPI, that’s for highly professional gamers.
Similarly, a designer who want to do minute changes needs a sensitive mouse for doing the same.
Remember, DPI is not some software stuff but it is in hardware and changing DPI makes the mouse more or less sensitive to your movements.
That’s all for DPI, let’s move to Pooling Rates now:
Polling Rate is the number of the time the mouse sends the signals to computer reporting its position. In simple words, if the mouse has a polling rate of 100 Hz, that means it sends its position to computer 100 times a second.
A higher polling rate will decrease the time between the movement of the mouse and the movement of the cursor on screen but it will end up consuming more resources. Similar to DPI, even some high-end mouse have the feature of changing polling rates. I don’t think it will be ever useful to me.
That’s all for today
