- You've probably used a mouse today. But do you know how it works?
Check out www.pcbway.com/ for all kinds of PCBs, easy ordering, and quick delivery. Take a look at their PCB Assembly, for an inexpensive population of the components on your PCBs.
In this video, we explore the different parts of a computer mouse and we'll focus on the optical navigation system. Specifically, we'll look at how exactly computer mice can track their movement on a mouse pad. Finally, we take a look at the difference between gaming mice and normal mice, and we explore DPI or dots per inch and how different mice have different amounts of DPI.

Mind. Blown. The amount of research and engineering that went in to developing a device that people don’t think twice about is truly astounding.
And it only costs you a few bucks as well
ua-cam.com/video/wHbDFo8GoK0/v-deo.html💯🔥🔥
Humans range from extremely smart to extremely stupid.
@@DM-rc4yu Ok
so many things are this way
if civilization were to collapse almost none of this could be replicated
The amount of time spent on making this animation is just immeasurable than the attention this channel gets..
I know right, it is such a crime that they have so little views :/ We need to share the hell out of them!!!
I TOTALLY agree with you!
@@rajisg ៏
@@rajisg Well, before i read your comment, i already shared it with some people who are electrical engineers who build stuff like this and even they were impressed
From modeling to Render atleast 3-4 week's worth of work
I was honestly expecting a surface level video, glossing over much of the technical details. I was instead blown away by the detailed explanations without getting overly technical and stunning, highly relevant animations. What a treat to watch! Keep up the good work!
same! Perfect video!!!!
Yeah these videos are surprisingly good. I wonder if the narrator is a person or AI.
@@Rockyzach88 I mean I think it probably is a person because if they invest that much into the animations they prob afford animations but yeah it sounds like an AI
The attention to detail, top-grade image rendering of the animation, and the core message are just amazing. My perception of the mouse is forever changed.
imagine converting your mouse into a webcam.🤣🤣🤣
I will never see a mouse the same again . Respect to all those brilliant minds and thank you Branch education for creating such an amazing video.
L
More importantly it's all affordable.
@@brodriguez11000 yeah
@adhithya you are a genius now 😹👍
metoo
I miss the days when you could take the ball out of the mouse to prank your friends. Great video once again!
Those were the good times!
You still can. I use trackball mice everyday at work to avoid injuries.🤓
We used to take those our from the mice in out computer labs and play catch with it. Good times
Hello Jared, love your content 👍🏼😁
cover the sensor with post-it
The technology itself is nothing really crazy, but when you take into account cost (down to 5 bucks) and reliability (thousands of hours with zero maintenance)... that is really unbelievable! What an accomplishment!
it would cost very much if not for mass manufacturing
yeah, creating abstract bicubic interpolations from scanning a surface using light rays in length of micrometers 17,000 times a second to capture a movement of your hand precisely beyond human capabilities is not anything crazy.
@@dabartos4713 and they only covered one technology
@@dabartos4713 yeah man, I was thinking the same. I'm having a hard time staring at my mouse and trying to process this information
@@dabartos4713 From a technology perspective it's the most basic thing, my microwave is way smarter and complex than a mouse. On the other hand a computer processor, having billions and billions of transistors, each having the ability to be turned on and off individually to perform millions of operations per second, all this happening on a scale of nanometers at temperatures in excess of 80C with a working lifetime of decades with an extremely high reliability, now that is crazy, not to mention how each processor takes months of extremely precise work in environments where a spec of dust could destroy the whole thing.
I have this as MX3S as my mouse and I use it almost 15 hours daily!
I will never look at tit the same way again!
Thank you so much & much props to Branch Education for this incredibly meticulous & in-depth video!

Fun fact : You can take your smartphone camera and point it at the bottom of your mouse and actually see the infrared light.
Dude I don't know who the heck you are, or where you came about, but your way of teaching, explaining, is amazing! Literally, please do not stop making content. The way you say it too!!!! Gosh. You have my support!
Didn't expect that the mouse I'm using has such high computing power. Thank you!
The quality of the 3D graphics in the video is also very enjoyable.
it doesn't actually taking that much processing power to do a comparison, especially on hardware based logic. It doesn't have to really "decide"
Fast Fourier Transform is O(N Log N). so only several 10 thousands of operations, which could be completed in a few loops on actual hardware implementation.
@@howardlam6181 No idea how you derive the number of operations from the O Notation. It easily could be less than 10.000 ops or a million
@@climatechangedoesntbargain9140 because its hardware optimized FFT. Most combinations of operations are combined and run in parallel. And it's only several thousands of pixels so it's easy to come up with that number.
Your mouse can probably run Skyrim
These videos fulfill my childish wish of knowing how everything works.
My parents could not always explain in such detail
Do you really understand how something works after one video? It is definitely helpful, just not enough to get intuition.
We'll never know how everything works, simply because our lives have limited amount of time.
Why am I saying this... I have no idea...
@@opst1704 without going to the philosophical level, I think I now have a general idea about how computer mice work, at least the stuff with the algorithm etc. 😉
At least it satisfied the aforementioned curiosity 😂
amazing
@@opst1704 of course not one video but this video does satisfy one of the wonders what a child's mind could think of.
rugs are better lol
The mouse knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the mouse from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the mouse is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the mouse must also know where it was.
Thank you. I was looking for this comment!
Great video! You understand how people understand. Science communication is so so so hard, but you've laid everything out in a really concise and precise way!
How can someone explain such a complex thing in just few minutes hatsoff to your talent dude I still can’t believe I am watching this free
Like, duh. You can google it by youtself and find out more in an hour. UA-cam is dumbing people down and makes them lazy
@@MrBratkenSolov Why did you click on this video?
@@MrBratkenSolov this is a very high level video, googling this stuff will lead you to lower level resources which you probably won't understand
@@MrBratkenSolov there's a thing called time saving
@@jayto3909 His right about one thing it makes people more lazy
"Prehistoric mice use a ball" 😂 wasn't expecting that. Lol
me too!! he finished me right there
bro we're prehistoric D:
In times when history did not exist, mice uses a ball to track their paths . .
Low blow ☹️
I have a couple mouse balls lol. I think I have every type of mouse. I got a high end gaming mouse, middle end mouse with a laser, then I have a mouse with a red LED light and a ball mouse. Also to note some newer mouses use balls still because they are cheap and make it a modern look. The mouse my mom uses for work is mostly a comfort mouse that also uses a ball pretty cool
Wow, compliments to this video. I love the in-depth breakdown that goes into the science, math, and engineering. It was also fun to see the MX Master 3 mouse that I use for my desktop in 3D for the video. Lastly, I'm old enough to have used pre-historic mice in my lifetime. How times have changed.
seen this channel ages ago, loved it sm, forgot ti subscribe, found again and love it!! crazy well done and spoken
For those interested, the little SoC (with the red dot) near the imager chip is a --muRata MBN52832-- Nordic Semiconductor NRF52832 which contains a 32bit Arm Cortex M4F with built in FPU processor with 64k of RAM and 512k flash storage. Here's an interesting tidbit, the Cortex M4F has enough processing power to run Doom, so technically if you were to add a couple megabytes of ram and a display to this mouse it could run and control Doom by itself.
thats insane
Can you post this again in English please.🥸😏
@@HalfWarrior last sentence is in English.
Shows how insanely far we have come with computer technology
mind blown
The attention to detail on the 3D rendering is impressive. It's so good you'd think he was going to sell you a mouse. Great voice too, and great pacing.
Do you know which software is that?
@@uusfiyeyh blender it is. They have given the details of the software used in this video in the description.
@@sergiovalenterodriguezmorq537 it's Blender and it's great and it's free, if you want to learn it go make a donut with Blender Guru's tutorial, he's awesome.
People who have done image processing themselves understand how utterly mind boggling that processing speed is and it's even more impressive when you realize that your mouse is able to continuously do all this for an entire year on just a single battery.
Just so you know not all modern USB Mice use batteries
Many still DO use a USB Cable that plugs directly into the USB Port on a Laptop
For example wired devices respond up to 100 times faster compared to its wireless counterpart
@@stephensnell5707the lowest latency mice available are all wireless models.
Excellent video. I’m an old electrical engineer but just never thought much about how optical mice worked. Nice bit of explanation. Getting a vertical mouse for Christmas, in preparation for a new desktop build early in the new year. Hope the vertical style will better suit these older, stiffer hands. The hard part will be to move the mouse without thinking about your fine graphics and lucid explanations.
It's beautiful to see this channel growing rapidly.
The animation quality and detail is just astounding and the explanation are always technical but not too difficult to understand.
It's just perfect
It's not growing as it should, compare to other stupid channels tbh . Been years since they started. I find it underrated.
The PCB animation is so high quality it looks life-like at times - amazing!
My Little Pony :3.
I've been designing computer mice for a living for 20 years but I still learned things and enjoyed the video. Thank you Branch Education for making such excellent videos.
That's amazing! How do you get into such a carrier? Would you mind sharing your experience and general tips? You don't hear about such carrier paths often! Cheers and take care.
Stop lying We work together at McDonald's.
I highly doubt you’d learn anything from this video, if you’ve been in this industry for 20 years. Please, tell me what information you received, that you didn’t have previous?
@@jamesbizs He could design shape of the shell. People in a company aren't experts in every area.
@@jamesbizs Is this an insult or compliment
One of the best educational animations I have ever seen! Hats off!
I was using mice back in the ball days and it's so awesome to see that we've replaced the ball with what is essentially a camera (no one misses cleaning out the ball and the rollers!). I knew pretty much how it worked, but this video filled in so many blanks, and knowing the insane data processing speeds of thousands of 'pictures' every second is truly mind blowing. How do modern mice work? They're constantly scanning the table and thinking about the imperfections, tens of thousands of times a second. Incredible!
"It would take over an hour to cover all these technologies in depth." Please by all means! An hour of this content is worth watching. Amazing, everyone should know this stuff.
it's really incredible how deep the rabbit hole goes. Theres always one more layer of complexity underneath. No one ever really knows how everything 100% works end to end.
That's the beauty of society. There is virtually no field where only 1 person can construct it all. From medical to space rockets to music tech to automobiles to computers. You do your part, your job and someone else moves the chain along. That's the essence in everything.

I never expected to find explanation video with such an insane production value for this (seemingly) simple question.
Prehistoric mice used a stick 😄
Phenomenal video. Just wow! I'm a "prehistoric" geek and knew exactly how optical mice work, but I've never seen this level of quality in an explanation before. Good content.
Being a computer engineer myself I wasn't really aware of the complex engineering and effort it took to build a small optical mouse....Your video is a gem 💎
are you sure you're not a software engineer.
just kidding, this profession is so extensive that one cannot know everything.
your not an engineer not a proper one at least
@@mohamedelhaddade6371 Agreed with your second point 😁
A computer engineer shouldn't be expected to know these stuffs either.
DSP
Cross Correlation
Control System
Image Processing
etc are all core subjects of Electronics Engineering.
People trolling you might not have any idea about it.
BTW in Mother Russia a 5 year old kid design these. Come to Russia.
@@KejriwalBhakt Oh thnx for being so kind enough and it's not an issue bcz I don't pay attentions to trolls ❤️❤️❤️
This video answers a question I've had for over 20 years. Thank you for your incredibly clear and simple-to-follow explanations!
Thay did thay best , use better mouse pad 🏁
I don´t want to know how much effort your Videos took. It is just so good for understanding complecated technologies like that!
The animation nails it. Goes perfectly with the great explanation.
I just got recommended this video and gotta say this is insane!! The structure, how you go from level to next level of detail, the clear and accurate writing, the clear and comfortable voice.... This is great, thank you!
Just awesome!
The simplest thing is always the most complecated one.
Thanks...
This video was one of the best informative videos I've ever encountered in my life. I'm truly in awe at the level of detail that the narrator went through.
Can you please cover all other components?
Man, the voice. It feels like GOD is trying to explain everything too me. And I'm so desperately listening all of it again and again.
I have a mice infestation in my home and this definitely helped out. Mice tend to move fast and they take lots of pictures. Thanks.
You might want to consider replacing your floor with glass tiling, that way older mice can't get a good grip and run away from you.
Man, in the days before wireless, they were much easier to catch
Have you tried removing their balls?

Amazing video, the quality of the information, the very well written speech and terrific graphics made the video amazing. Thanks!
As someone who owns the Logitech G502 Hero gaming mouse shown in this video, I had an a-ha moment watching you explain high DPI!! That interpolation that you explained translates into an actual difference in user experience with high DPI vs low DPI.
At higher DPI, even as low as ~2000, I notice a sort of smoothness to the mouse movement that isn't present at 800. The higher you go, the smoother this feeling gets, almost as if your mouse is going down a long water slide with smooth turns and centrifugal forces. High DPI means stronger gravity and smoother but sharper turns. I realize now that that feeling is because the interpolation algorithm is essentially smoothing out the textured surface that the mouse is capturing, which is fascinating to me!
So when pro gamers are said to use 800 DPI, this helps make sense of that. It's the most accurate DPI, where your hand movements are directly translated into movement. An interpolation algorithm can introduce tiny amounts of error there, or the smoother movement can make precise starts and stops of the cursor harder to achieve.
So thank you for this great and super interesting video! I can't wait to watch more.
The great graphics synced with audio explanation is the best way to convey information to people. This video is a gem of educational material in the Internet.
I am sooo glad these examples and breakdowns are from such modern devices! All too often these explanations are from nearly outdated technologies we barely use anymore, just so they don’t have to explain as much. So many props for the awesome and explanatory visuals, the easy to understand writing, and the commitment for quality education for all!
Imagine turning your gaming mouse into a webcam.🤣🤣🤣 Westley. Crusher🤣🤣🤣
this is by far one of the best videos i have ever seen, informative and beautiful
30k?
Take more 100k and yet a thousand more.
Well deserved, dense content and clear deliver, thank you so much for sharing
I am glad you mentioned trackballs. I don’t feel that old but remember using them. A mouse pad was a necessity back then. It still surprises me how well optical mice work on almost any surface. I remember the ball needing to be cleaned once in a while to keep working properly.
My husband has a mouse with a trackball, but the ball is on top of the mouse and moved with your fingers. Interesting variation on the basic design.
Zoomers will never know the pleasure of cleaning the three dirty mouse wheels inside.
@@vertyisprobablydead Done lots of those for people. Those old units could be quite "organic" inside. One was full of chewed bits of fingernails.
I didn't know ballmice needed a mouse pad. Me and my family has been using ours on the plain wooden tabletop back in the Windows XP days and it worked fine.
Occasionally, though, the ball would get stuck and had to be cleaned, ofc.
@@vertyisprobablydead right, because every time new technology comes out, the old tech is immediately purged from the face of this world and only exists as memories in people's brains from then on, duh!
I grew up with compact cassettes, VCR, NES and the Gameboy Pocket, but not in the 90's! 😁
@@LRM12o8 Yes, eventually the third world will be able to afford the new technology long after it stops being trendy, that's a given.
This has got to be the most clear explanation of any technology I've ever seen. It's just detailed enough to capture my attention and I actually learned a lot from this.
No way I finally found you, saw one of ur videos on one of these TikTok channels that steals content and removes watermarks, I thought the video was so cool but couldn't find the source nowhere, so glad I found the channel 😁
awesome work, top quality, congrats!
The amount of work in this video is simply impressive
I noticed that when i hold my mouse so that the sun would shine on the backside of it the curser would move on its own in random directions and now I know why. Thank you for that informative video, I really enjoyed it
The visuals are super helpful, great video!
You're a gold standard for educational video for me! Love your work!!! ❤❤❤
This channel is criminally underrated, great video as always sir!
It's amazing how the simplest things can be very difficult to produce.
This reminds me of a video I once saw, about a car's steering wheel. It's unbelievable the amount of calculations that goes into making a steering wheel work
Yeah! And from that perspective they are really not "simplest", but rather "everyday" things.
Just thought the pointer is moving here and there on the screen but wow what a technology behind a small device. Brilliant creation..
Awesome. It's always cool to read about sich things, and realize that they've been developed for so long time already
I love how you used an MX Master 3 which is one of the most complicated mice.

Fantastic description, thank you. This also explains why I find a blank sheet of paper to be the best 'mouse mat'
What an amazing process for teaching. Love the voice work too!!!
How simple the technology looks compared to the processes that goes into it is all on one side of the scale,.. while the quality of this video is equally matching it on the other.
Animation, explanation, and flow is really well thoughtout and greatly executed.

I'm impressed. Well done video! ❤️ I just subscribed.
The technology that lies under the palm of the hand is amazing
Its amazing how much thoughts and effort engineers have use to make a mouse. A lot of complicated math, physics, computer engineering, etc.

I didn't realise that a computer mouse that is so basic could be so complex. Im truly fascinated. thanks branch edu for shedding light on this.
The mechanical biology of a mouse!! Awesome
These videos blow my mind and always give me a new perspective on technology that we often take for granted
Thank you Mr New Vegas! Jokes aside, thank the algorithm that sent this video my way, sadly a tad too late, was the teacher for a programming class that tackled the use of DSP's and how they function, really loved the video and likely to use it as an example
I own exactly this model and recently tore it apart because I dropped it once too often. So I was surprised to see such detailed and accurate animations!
First I thought that you simply ripped some marketing animations but when the animation went on and on, perfectly depicting the highly technical contents, my jaw just dropped.
I love 3D models explanation videos and i appreciate the effort put in making them
It makes me feel privileged and thankful to live in this modern era, to experience such a complex and marvelous technology which would blown the brains off of the people from past 50 years.
