Just a few days ago the force trackpad had made its way to the 15 inch Retina MacBook
Pro it now joins the 13 inch Retina MacBook Pro as well as the 2015 MacBook but what's
so different about this force trackpad and what makes it special among all of the other
trackpads that are available so basically the old trackpad in the previous MacBook Pro
and MacBook Air is it had this hinge and when you click on the from of it the hinge just
basically moved up and down and it just basically... like literally the trackpad went down and
up when you clicked on it clicks were detected by a microswitch and that's as simple as it
is now with the new *Rooster* trackpad on the 15-inch Retina MacBook Pro as well as
the 13-inch and the new MacBook the are basically no hinges and the trackpad doesn't actually
move up and down instead there are these tiny little springs that don't really allow it
to move at all but what these springs do is measure the pressure and they don't actually
move and they are completely silent but instead what these springs do is they send feedback
to the taptic engine which is basically just four sets of electro magnets that when electricity
is added to them they just pulse and that's basically what give it the click sensation
when you press down on the trackpad it doesn't actually move anywhere but it feels like it
is clicking because it basically detects that there is pressure on that area and then these
electro magnets just pulse electricity is just sent through them in short pulses that
kind of give the feeling that it is being clicked and Apple basically refined it to
just feel like it is a click and it actually works really, really well I mean the first
time that I tried out this laptop for myself I actually forgot about this whole force touch
thing and the fact that it doesn't actually move I was actually convinced that it was
moving and I was like telling my dad that it was moving but it actually wasn't and when
I got back (home) I was like pretty embarrassed because it actually honestly felt like it
was moving but anyway that is kind of getting off topic anyway so this is how the trackpad
allows for things such as force touch because basically when you just push down further
it just sends out these pulses again so it feels like you are pressing down even harder
so when you press down just a little bit then it just sends one pulse, it just buzzes once
and then when you press down again it sends another one so it feels like it is going down
lower and that's basically just how it works and it literally feels like it is clicking
and then clicking down again it is something that it's really hard to explain you just
have to try it out for yourself but anyway that's the real jist of it that's basically
how it works and it is really, really clever how they did it and it is something that I'd
really like to try again for myself now that I actually know that this is how it works
and it's not actually moving up and down so if you have this laptop at home and you didn't
actually know about this feature be sure to tell me in the comments and if this is something
that you'd really want to try for yourself or you have tried it but you don't own this
laptop be sure to tell me down there too if you liked this video be sure to give it a
like and subscribe if you want to see more stuff like this and yeah that's basically
it thank you for watching and I'll see you in the next video BYE
