iPhones score highest touch responsiveness, more than twice as responsive as Android and Windows Phone devices

iPhones score highest touch responsiveness, more than twice as responsive as Android and Windows Phone devices
Have you ever thought just how responsive to touch your device really is? This is after all a key factor in determining how fast it feels, and now researchers from Agawi came up with a benchmark test that measures response times down to the millisecond. The test is called TouchMarks and relies on an Arduino board, a few 240fps slow motion cameras and as many as 50 repetitions to make sure the test is correct.

The end results are very revealing and they show that currently the iPhone has the fastest response times of any device out there. Faster than any and all Android and Windows Phone devices, and the difference is noticeable.

To understand these results (right below), you’d need to understand touch responsiveness, or the delay between you touch the screen and it reacts. Earlier research has shown that the current average of 100ms comes with a delay that the user can perceive - try writing something with a stylus and you’d see your writing trail your finger with a noticeable delay. At 50ms it’s still noticeable, but not so much. At 10ms, the delay is still visible, but much less. At 1ms it’s gone - the human eye perceives it as if it’s not there.

So while we’re still way off that 1ms ideal, it seems that on mobile phones, the Apple iPhone 5 is the fastest one scoring 55ms response times, more than half that of say the Samsung Galaxy S4. Even the iPhone 4 is faster than all Android and Windows Phones, and the test does not yet have the iPhone 5s results. So with no further ado, here are the touch response times for various devices:

To better understand the methodology of the TouchMarks test, here is an explanation of how it is conducted:

"Agawi's Touchscope was built in-house to get multiple samples of touchscreen response times very quickly, the Touchscope measures App Response Time (ART) by capturing the time delta between activation of the Force Sensitive Resistor on the glove and the Light Sensitive Resistor positioned over the device. The Touchscope is based on the Arduino platform and uses easily available electronic components so it's easy for any electronics hobbyist to replicate. The specs and code will be released soon."

All in all, it’s great to see more tests, and more measurements that would help us better understand why a device feels as fast as it does. Hopefully, phone makers on the Android and Windows Phone camp will quickly realize the importance of this and how it is intimately linked to the quality of the user experience. And to better understand response times, and the goals for their improvement, take a look at the video below.

Wow! So that's how you technically define "lag"? Very Informative article PA!

Android users will still find a way to say 'no it still lags' and will site some article which only shows other Android users opinion on how they think Apple lags.

This test can't rehabilitate iOS 7 lag since this test is about screen responsiveness to touch and it has nothing to do with iOS 7 as OS lag.

I think it does actually. I am a die-hard android person but I played with an ipad recently and I noticed the touchscreen is very responsive but I thought it was due to the fact that I always use screen protectors on my own devices. Swiping was really smooth on the ipad and if you have been using iphone for long, I can imagine the first impression of an android phone lagging.
This responsiveness is one thing iphone users define as lag.

Review this comparative bettween Nokia Lumia 920 and Nokia Lumia 928

iPhone 5S is no match for Lumia 920... obviously this resarch does not count

chill bro! lag is due to other stuff also

Oh God! That was purely unintentional. I was not supporting anybody. I just found the article (and the embedded video) informative.. I'm not, in any ways, responsible for the war that is about to break out. *Peace* :D

I wonder who paid for this study beacause Human Brain "can process" data received by the eyes between 150 and 300 ms.
All the phones listed are under 140 ms ....

There is no way human brain can process data every 1ms

Where do you get that 150ms to 300ms number? Movies need about 25 frames per second to be smooth. Games need even more, about 30fps to 60 fps. Even at 25 frames per seconds, that's 1 frame every 40ms. 150ms is way too slow.

yeah. Just try to watch a movie with 3 frames per seconds and tell me how you feel.

Why don't you ask google ? it is very simple. If you can read text in french language, read this

Le temps mis le cerveau pour traiter l'information fournie par l'oeil se situe entre 150 ms et 300 ms.

150ms will translate into less than 7 frames per second. and 300ms translates into 3 frames per second. Those figures are way too slow for anything.

It doesn't matter what you find in google, just use your common sense. Are you telling me your eyes and your brain cannot process more than 3 frames per second? I am sure my brain can.

I'm telling you scientists in the world agree that human brain can process data from 150 to 300 ms.
It is very simple.
I'm talking about Scientists.

And I am telling you those numbers are wrong, at least in this context. 300ms is way too slow for watching any kind of movement on a screen.

You've convinced me, even if jelly Bean is at 60FPS, the S4 screen won't be able to render it properly.
It's responsivness should be at around 16.66 ms to handle the FPS.

Scientists once believed the world was flat.

Or, that the Earth is the center of (then known) universe as in the Sun revolved around the earth.

Here is one truism about science and scientific methodology, a scientific theory exists until a better comes along.

maybe you mistake that time with the human reaction time (time you need to click a button after a signal, which is around 100-400ms). otherwise your claim is comlete utter bullsh*t

Iphone 5 screen resolution: 640 x 1136 pixels
Galaxy S4 screen resolution: Full HD

For the Iphone 5 and Galaxy S4, the responsivness cannot be noticed by human brain, there are both too fast for the brain.

This study is just for Marketing

The theory is that, because iOS apps are programmed in Objective-C (which is closer to metal than what Windows Phone and Android apps are coded in) might be the reason why.

Why not they compare lumia 920.

the best screen on WP is on Lumia 920, this is just lag in research
