How does Multitouch work?

Have you ever thought of your smartphone's multitouch as similar to your skins ability to sense touch?
We take for granted being able to sense our environment, but designing an electronic device's ability to sense the environment is no trivial task. Learn about how multitouch works in this video!

Make this guy famous! Your teaching skills are amazing!

[seetaramparwal]

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 YouTube .
Wish you all the best for your very bright future

[vikiteodor]

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.

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

[barrygorden]

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

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!

[coolbits]

Another excellent video. The explanation was thorough and focused.

[martinmpaz]

Years waiting for this explanation. Thanks!

[BangMaster]

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.

[batzlat]

Great and simple to understand video of a complex concept!

[darkminds]

Pls do continue your work. Good job😍✌️

[forrestberg]

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

[HytoGuitarstyle]

Dude you deserve more subs. Saw 1 vid I loved how easy to understand with cool and simplistic visuals and illustrations. Thx a lot

[ShomeAvi]

your explanation and animation are top notch..

[masoudhasany]

Great video. Do you have any episode explaining resistive touch screens?

[JoaoVictor-uodn]

Please continue the work. Nice video!!

[vladarskopin]

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

[yasirurooj]

Great video understood a lot about the touch screen

[priscillatablante]

Oh wow, I love learning these things. And I like how its illustrated!
