How does Multitouch work?

Make this guy famous! Your teaching skills are amazing!

[@ITX635]

4 years later he was famous now

[@seetaramparwal7503]

Great video I understand how difficult it is to make such high quality videos ( the animations and the editing ) I think this is a very underrated science channel on KZbin . Wish you all the best for your very bright future

[@vikiteodor3353]

This channel will have a high peek in views some day

[@ZachHixsonTutorials]

Great video! I like how we are finally getting into the "branching," part of these videos, and I think that's a really good unifying theme and works well. One criticism is that the main "tree," is a little dense and hard to read. I think if it was 2D or organized differently it would be really cool to be able to track our progress as we go through the series. A neat trick to try might be to make the current branch glow, and have the rest get darker as the light travels through the branches.

[@CptChesko]

Crystal clear explanation and visuals, and a fascinating subject-thank you for satiating my curiosity!

[@BangMaster96]

Thank You for this wonderful video. I'm learning so much about how things work, it makes me realize how much i take everyday technology for granted. Thanks to all the Engineers who make our modern world possible.

[@jo7391]

Love it! Short and sweet

[@frykes]

I've been trying to learn how capacitive multi-touch works for a few weeks now. I'm glad I stumbled across your video, you did a great job explaining the concept and your visuals are fantastic. Keep up the great work!

[@martinmpaz]

Years waiting for this explanation. Thanks!

[@darkminds5391]

Pls do continue your work. Good job😍✌️

[@barrygorden8338]

The graphics are beautiful and add a heightened level of clarity to the explanation.

[@forrestberg591]

It would be interesting to see a comparison with the pros and cons to capacitive vs resistive touch screens

[@BranchEducation]

Thanks for the good idea!

[@chrisbrophy472]

Always great videos

This lesson is so amazing. Thank you so much for the explanation, God bless you man!

[@He-Is-One-and-Only]

Great job man......huge thanks.

[@arvindhganesan]

At 2:09, shouldn't the direction of electric fieldlines be in the opposite direction, i.e., emerging from the positive charge and into the negative charge? Since it produces negative electric field, it was have inward flux right? Great explanation though, highly appreciate the clarity in the concept!!

[@canvey555]

Thank you very much for your video there is such clarity and position to help understand the explanation

[@kevinzebrowski6766]

Thank you so much!

Hi. Did I heard a Sound, generated in the Software Reason? Anyway. This is one of the best Video Presentation Structures I have ever seen... [Exaggerations about my exaggerations are... ;) ] Thank You very much and please do more "Branches".

[@sagarsutar7187]

I appreciate you for education video

[@obada.]

I don't often comment as long, but this channel really needs to spread out, these animations seem difficult to produce and the final result is WOW, I don't get why this video is 28k views only, it deserves a lot more, isn't this heavily underrated channel better to watch than those other BS channels I don't want to mention?

[@myrodin1210]

Im learning!!!! How dare you. I need more now!!!

[@abdelhakouinharoune7504]

awesome accurate content , love the theme. keep up the great work man !

[@null-calx]

loved your job if you could explain proximity sensor, battery charging and discharging, vibrations, memory, r.a.m. and backlight control

[@Pradeep___Kumar]

Sir plz Make a video on SoC how it works and what are inside

[@ujjawalmauryaum]

nice video

[@mcsin]

You and lean engineering should work together or make a new channel together. I think it would help many people to understand more about technology.

[@BranchEducation]

yup! We will do collaboration soon. Should be fun!

[@infinity2kx]

Nice, do one on how and why brain waves activated by hormones can actually affect external reality including larger scale constructs such as pheromones which may alter variables in the general experience pool.

[@BranchEducation]

Sorry, I don't know much or anything about this.

[@infinity2kx]

@@BranchEducation I guess do one on E.E.G. technology and nervous system controled tech then? that's a beginning. I appreciate these a lot.

[@gokaytaspnar1355]

Nice

[@Daniel-ru3dq]

Hi Teddy. What makes a capacitive touchscreen more responsive in comparison to a resistive touchscreen?

[@BranchEducation]

Most of it depends on the number of rows vs columns. Resistive touchscreens have really good applications where pressure needs to be sensed accurately. I'm sure engineers can design resistive sensory inputs for different applications. For example, I wonder whether engineerings will apply resistive sensing arrays onto the limbs of robots.

[@garthwhitelum1971]

Moooooree videos please.

[@RohanKrSingh-yh8bn]

Nice channel....

[@Techlifeandmore]

I have an iPad, HomePod, Apple TV, and Apple Watch. Of course, I’ve got an iPhone to. But, how does the touchscreen work in the Homepod, Apple TV remote Trackpad, Apple Watch, and iPad?

[@ItsDisliked]

nice

[@stonefreak5763]

For something at the Size of a table, could you make a System out of multiple Touchscreens, so you can have the Delay of let's say a Tablet, but still the Size of a Table?

[@Daniel-ru3dq]

Among current touchscreens is there a limit to the maximum number of touch points that can be detected?

[@BranchEducation]

Yeah- from the many white papers I read, they quoted around 10, but in the patents, they mentioned closer to 20 (citations are in the episode notes). That goes to show the difference between mass production applications and lab results. I didn't get into the software utilization of 10 distinct touches, but I bet software writers have a hard time using more than 4 points effectively and consistently.

[@earumamaadu]

If the electric field is projected above the glass then why doesn't the touch work when I put my finger really close without touching? But touch still works on top of another protective glass layer

[@BranchEducation]

I don't specifically know.

[@HACKINGMADEFUN]

Learn engineering sent me

[@thangavelv2305]

Do more videos broo......

[@BranchEducation]

working on it.

[@hazemdweik6321]

I'm new here, I liked and subbed, can you show us how hardware works? If no, no probpem

[@BranchEducation]

Yeah! We will get to the rest of the hardware elements throughout the videos.

[@linuxgaminginfullhd60fps10]

I always had problems with those touchscreens. I guess my fingers aren't conductive enough. It was much easier for me to use those old resistivity touch screens, which could easily recognize nails and sharp objects. Oh, also these capacitance based touch screens are terrible if it rains or if some water ends up on the screen.

[@BharathinfinityHegde]

2:18 How is the change in positive charge measured?

[@eggyrepublic]

Since a change in charge causes a change in voltage and voltage can be converted into a digital signal through an ADC, we can measure the change in voltage of each row. His point was that theoretically it's best if we can measure each individual square, but since that would be very difficult and cumbersome to do, we instead measure the entire row. Doing this causes the problem that we cannot tell which square have what voltage, all we know is the total voltage. Therefore, the "scanning" is done such that only one column in each row can be activated at a time.

[@chrisli5215]

Nice work! Appreciate it! But I dont quite understand the readout principle. Does the ADC measure the votage of the whole column every timestep? Btw is it similar to how the CCD read out the charges?

[@BranchEducation]

An entire column is read out by a set of 80 or so ADCs in a similar format to CCDs.

[@chrisli5215]

@@BranchEducation Got it. Thank you very much. Keep up the outstanding work!
