Microsoft has created the first stylus with no perceived lag: the new Surface Pen


Microsoft claims to have created the “fastest pen in the world,” but what does that even mean?

It's quite simple actually: after years of research, Microsoft has finally been able to make a stylus that works with almost no visual delay, a paramount change in the experience. This is the new Microsoft Surface Pen, and it's got other super-powers as well: a whopping 4,096 pressure levels and the ability to recognize tilt, so that you can use it to shade things, just like with a regular pensil.



Diving deeper in the tech details, the break-through achievement with the new Surface Pen is that it works at only 21 milliseconds of latency. 

This number alone is hard to understand, but you understand it better when you see the below video by Microsoft Research. It shows a typical device that works with a latency of around 100 milliseconds, and compares this to a futuristic, 1-millisecond input. We are not quite at those levels, but the Surface Pen is getting the stylus much closer to that magical territory.


Compare to the previous Surface Pen, this new edition is over two times more accurate, with four times more pressure sensitivity.

“We did a huge step with the pen, a massive step,” Surface co-inventor Stevie Bathiche said for The Verge. “I’m so pumped about this.”


Another part of the Surface Pen experience magic is the PixelSense Accelerator, a piece of custom silicon that enhances colors and interaction for the 12.3" PixelSense display on the Surface Pro.

The Surface Pen is available in Platinum, Burgundy, Cobalt Blue and Black. The Pen will be backwards compatible with earlier Surface devices, but certain aspects like Tilt might not work.

Which one is best when it comes to functionally Apple Pencil or S Pen or Surface Pen?

it's not the stylus.. it's the OS..

Lol, Microsoft is hilarious, still not up to par with Apple Pencil. Usual Mafiasoft marketing......

Lol @ "not up to par", it's beyond the pencil, it's got a tail eraser, 4 built in shortcuts, magnetic storage, and all year battery life...

The Surface Pen has more functionality than the Apple pencil with all its buttons etc and that you don't need to charge it up every 5 minutes, but the one thing that the Apple pencil does well, is...be a pencil. It does one thing and it does it well.

Technically the Apple pencil is really good. It's very accurate. What it lacks is functionality and feel. The Surface 4 pen has the changeable tips which make it much more pleasant to use, which the Apple pencil has that annoying plastic on glass feel while you're writing. You also get annoying taps of the plastic on glass which you don't get on the Surface. The pencil lacks the eraser and select buttons which although you can use on-screen substitutions, this makes the process more cumbersome. I'm interested to see how the tracking accuracy and slow diagonal lines turn out on the Surface. On the Surface 4 they weren't great.

£979 for the i5/128gb version. Ouch. Then you need to add on the extra for the keyboard and pen. You're looking at £1200 all in. I got the Surface pro 4 with keyboard for about £950. Quite a difference, probably due to the crap pound. There's no way I could deal with a mere 4gb now either. Just load up PA on Chrome and all your memory has been gobbled up. Glad to see that they've improved the pen, I hated the pen on the 4. Not sure why they have to copy Apple by removing the clip. They'll be removing the buttons next.

No more pen clip? That's a ridiculous and backwards move. It should at least come with some pen cap with a clip like a normal pen...

Microsoft knows a hell of a lot more about this than apple . . . . . . . . . . . . IBEGINNER HAS ONLY BEEN A MEMBER SINCE 4 HOURS AGO LMFAO .... TROLL

The pen is now also sold separately in order to bring the price down to exactly that of the iPad XL ($799 although with quadruple the storage, 32GB vs 138GB). Wonder how much the pen will cost stand-alone... Eitherway, no Thunderbolt 3, no sale.

Previous Surface Pro devices were $799 and included the pen.

probably the LTE antenna cost and decent speakers

And they had 64GB storage and no biometric authentication. The base Pro 4 was $899: https://en.m.wikipedia.org/wiki/Surface_Pro_4

PA, it's pencil, not pensil. :)

>> Diving deeper in the tech details, the break-through achievement with the new Surface Pen is that it works at only 21 milliseconds of latency. iPad Pro with Apple Pencil works on 240Hz. 240 Hz = 4.1666 ms. So claim : "NEVER HAS THERE BEEN A DIGITAL PEN LIKE THIS ONE" not completly true..

No, The ipad pro doesn't have 240Hz display and your magical 4.1666ms response time. Stop making things up out of thin air and your lying claims.

Unless CrappIe is lying, what he claims is 100% backed by what's on their website: https://www.apple.com/ca/apple-pencil/ "When iPad Pro senses Apple Pencil, the subsystem scans its signal at an astounding 240 times per second, giving it twice the data points it normally collects with your finger."

Latency and input per second are two different things

10. MrElectrifyer

Posts: 3960; Member since: Oct 21, 2014

Really? I think they're merely the inverse of one another. Hz = input/s. Latency = s/Input. So, 240 inputs/s = 240 Hz => Latency = 1/240 = 4.166 ms/Input. What's wrong with that thought? Do share...

And when does the Processing take place in your Theory ? :D

Imagine a long train going through a tunnel, at a speed of one car per second. Imagine that you can see both ends of the train. Now, there is a red car entering the tunnel. Since the speed of the train is one car per second, does it mean that you will see the red car going out of the tunnel in 1 second ? Nope. Because it takes some time for the car to go through the tunnel. - Tunnel = processing of the touch data by the CPU and GPU, - Speed = frequency of the touch panel, - The car going into the tunnel is when you touch the display, - The car going out of the tunnel is when the line appears on your display. Do you understand it now ? Even if the frequency is very high, the time it takes to process the data (latency) can be much longer (or shorter, if the tunnel is shorter than a car).

That makes sense and also explains why the pencil has higher latency in some apps than others. Thanks for sharing, lesson learned.

Doesn't mean the display can be updated just because the input has been measured. Get a grip if you're ignorant.

https://www.youtube.com/watch?v=GprJAYr4lu8 thsi shows how the Processing in Apps affects the Latency and that is something completly different than your Input per Second numbers from Apple.

Nope, a working frequency of 240 Hz doesn't mean that the latency is 4 ms. It means that the position of the time of the stylus is measured every 4 ms. There is absolutely no link between the latency and the frequency. A smartphone display's touch panel works at a high frequency and yet the latency can be higher than 50 ms...
