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.

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.

Should have rather asked for 100k+ likes,. Truthfully this video deserves huge huge appreciation....

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.

[@FlyingHosenlander]

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?

[@ZZ-vl5nd]

Awesome animations!

[@sjwimmel]

I like that you used my mouse for the demo. I'm not often one to recommend products openly, but this thing works great!

[@Tristoo]

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 is exactly what is used in lidar Remote sensing and navigation! It amazing to see how space tech has influenced consumer electronics.

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.

never thought visualization could reach this level, this literally makes me love these techs

[@atiqueraza9514]

The way they visually represent the complex math is amazing.

I rather not sort the price from Low to High for mouse. They really deserve it.

[@satyamsrivastava782]

Now I have a huge amount of Respect for my mouse. Hats off to the Developers.

One of the best educational animations I have ever seen! Hats off!

Wonderful Day after watching your Videos Impressive Animation ✨✨ Cheers

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.

[@spinnenente]

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.

[@daniloberserk]

@@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.

"Prehistoric mouse used a ball" I have used that particular mouse a couple years back

[@crazyedo9979]

"Prehistoric mice" And I was so proud of my Commodore 1351🦖 ☹️ Anyway. Fantastic video with lots to learn from. Nearly no one imagines the amount of fantastic technology packed in such a small device wich was unrecongnized common in our daily life. An interesting addition to this might be to look for "dark field microscopy" 💯👍

[@leaf16nut]

To think that stupid mouse sitting there is doing all that, within fractions of a fraction of a second, is pretty mind blowing.. Especially considering how cheap a mouse is, truly amazing technology!
