@@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
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!
@@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
I'm getting emotional from seeing that I can watch such - educative - well explained - beautifully animated - efficient content without having to pay a single penny. This is insane and I want to thank you for your hard work.
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.
@@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.
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.
@@TheMsr47gaming Where are you going after you die? What happens next? Have you ever thought about that? Repent today and give your life to Jesus Christ to obtain eternal salvation. Tomorrow may be too late my brethen😢. Hebrews 9:27 says "And as it is appointed unto man once to die, but after that the judgement
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 😂
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!
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.
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
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.
@@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.
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!
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 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 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
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.
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?
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 mose 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.
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!
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!
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.
"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.
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.
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!
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.
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!
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.
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 💎
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.
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.
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.
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! 😁
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
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'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
Just amazing, it's seems like a simple mouse 🖱️but all the engineering and science behind it, just wow. I can't believe I'm watching this much helpful content for free. Love you guys for this much information in a very short time
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.
The most Hardworking and underrated Person on RU-vid. He deseve more than he is getting. I also have a question that why the people who provide knowledge are most of them Underrated but The quality of people here are priceless. I think this is Heaven
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.
I got lost at the last part of the DPI, but I really APPRECIATE THE EFFORT THAT THIS VIDEO HAD! I'm not even an English native speaker, and this reached me on my feeds! So I think more people will get to see this! Very good video
That blew my freaking mind. That was so masterfully explained...I learned so much dense information with such ease. Somebody get this person to rewrite our education system.
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.
I swear I'm in love with this channel. Absolutely amazing videos. Such niche topics explained so simply yet so in detail with quality and comprehensive animations, leaving little to no questions to ask and covering other related sub-categories that make up that topic, fullfilling people's curiousity about how things work. Gratitudes.
Hah, saw this on the youtube home page 43 seconds after you posted it! Looking forward to watching it! (edit after watching) Indeed, quite interesting!
This is the second video i have watched created by Branch Education. I am utterly astonished by the quality and pure information provided. lets just say this will be far from my last video watched! I am eager to spend upcoming free time completing every video Branch Education has to offer! I cant wait!
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.
@@alexandrosfotiou6580 Microsoft also has good scrolling mice. I previously had Microsoft Explorer Touch mouse which was great, I loved that fast touch scrolling. But the mouse itself was less ergonomic and less functional than Logitech
We really take computer and its accesories for granted. Wonder every time when I come across such great presentations. Although not everybody will understand the cross correlation stuff but will get the gist of the techology right under their palms.
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
i always wondered how the red light in the mouse works but forgot to search it on google. now this video is recommended on my RU-vid and i do appreciate that
Never knew the thing just used a camera and such a brute force style algorithm. You have those IR RPM counters, and I always thought it was something more along those lines even though I don't really know how those work either. This is cool stuff, and great animations. Thank you!
This video was so good I subscribed immediately. I'm not kidding when I say it was one of the highest quality videos I've seen in awhile and thank you form making it. I never knew I wanted to know how my mouse worked.
Incredible video as always! But unfortunately there's some outdated info! Your description about how high DPI works on high end mice nowadays is quite different. Interpolation used to be the method before they released PMW3310 and PMW3366, back when mice used to have less DPI settings (sometimes just 2 for example), they used to have an "native" option and the rest was interpolated. However nowadays for most mice, they have native settings in steps, for an overall range of native DPI divided by 50 DPI for example. They measure and compare pixel brightness to accomplish that, it's possible because nowadays the level of ripple/jittering is very low on high end sensors. Even "smoothing" filtering might not be needed anymore. Also. Talking about laser sensor, if you're talking about something like the Philips Twin Eye sensors, they work VERY different then described here. However. High DPI is mostly an marketing big number instead of being something useful. You need just enough resolution to move consistently and precise in your desktop, which might be at MAXIMUM something like 2000 DPI, we lack enough dexterity to take advantage of such high values like 25000. There are a lot of other things more important for gaming mice... Like: IPS (Inchs Per Second) - Maximum speed that you can move your mouse before it malfunctions, also, max acceleration. LOD (Lift of Distance) - The height where it tracks the surface. Generally, you want to be quite low but at a height where it tracks every movement at a high precision of DPI (low deviation). High Polling Rate - You talked about that, but nowadays there are sensors capable of 8000 Hz out of the box. Also, high surface compatibility. Generally, you want a sensor that can track well at every type of surface without suffering with bad SRAV (Speed Related Accuracy Variance), sometimes called "positive acceleration". When you move your mouse for the same distance at different speed and get more output that it should. Used to happen with laser ICS sensors like the A9800 with less smooth surfaces. Also... You can get something like the Razer Pro Click (or Pro Click Mini) and it does work like an "gaming mice" just as good, they even work at 1000 Hz Polling Rate. There's not an "rigid" rule, you need to see the specs in every case. There's a lot of "Gaming Mice" from bad brands that aren't better then any office mouse spec wise. They just "look" different.
you are off on the dpi thing. That depens on how fast you set your mouse cursor in games/windows using a higher dpi setting with a slower setting in windows DPI > 2000 become usable especially for people using their mice mostly with their wrists not their whole arms like it is common today. DPI beyond 10k make no sense to me though and is solely for marketing purposes.
@@spinnenente it's pointless to use any option on windows settings besides the standard 6/11. Personally, I don't believe no one can have enough dexterity to justify something higher then 2000... But it might be useful at least for 4000 for some players in situations where you don't need pinpoint accuracy. But for the most part... It's just a gimmick. It might be useful for other applications, like robotics.
After watching what small chips with relatively low computing power cand do, I just cannot wait for quantum computers and the amount of futuristic gadgets we would be able to make with such immense computing powers.
very nice explanation & visualizations! Wouldn't it be more efficient for the DSP to first do the crosscorrelation and next do the bicubic interpolation on the result?
