Applied Sciences Group: High Performance Touch
Modern touch devices allow one to interact with virtual objects. However, there is a substantial delay between when a finger moves and the display responds. …

It’s all because of that pesky Dalvik VM, Google will get it down eventually.
Can’t believe I’m saying this, but KUDOS to Microsoft!!!
also if you play fruit ninja or infinity blade 3 or anything that involves swiping your finger across the scree.
Did anybody see that the things on the test pad are projected and not on the display. They shoud show 1ms latency on a real display not on a touchpad like bamboo
If only Microsoft can implement this in their new Windows phone. That would be phenomenal.
Yes it does. I believe the 920 and S4 numbers are actually about the same. Android is known for touchscreen latency (have an android myself, and it is quite noticeable when compared to an iphone). Look up Touchmarks Agawi and take a look at the numbers.
Disabling vsync gave me a significant improvement..
Also, S4 is running a really good touch panel
вот фигню же рекламят, давно уже такой отклик а не инновация!
The delay is more noticable on my L920 than on my S4. It has nothing to do with the OS.
It’s extremely rare that mobile displays can be overclocked.
Limitations are not only the panel itself but also memory bandwidth available especially with high-res equipment.
There was one exception with a Super AMOLED display but it was required to modify the kernel driver in a custom kernel. Also it was introducing issues as not all the LDI commands were passed correctly.
However the 120Hz displays are seen more and more frequently, and almost all 60Hz screens can be overclocked
Google, recruit this man!
Android has this thing called “Vsync” , which makes the issue even worse.
They’ve done some optimizations to VSync since 4.1, reducing the touch and overall latency, but it’s still there.
It’s present on all touchscreen OSes really.
It is engrained lag. The animations are redundant and make it seem like everything is slower.
All phones must be 1ms.Its just awesome 😀
Although no completely related, this demonstrates streaming applications or games over the cloud would fail due to even more latency introduced from the internet.

That would of course mean an average of 8 1/3 ms, as you don’t need to wait a full cycle, but only until the next refresh.
Great video and perfect demonstration!
It’s interesting to point that with current displays, it is impossible to reach a latency lower than 16.7ms as this is the duration of a frame on a 60Hz screen.
Consequently we need much higher FPS displays, especially on mobile or any other touch system.
I hope samsung watches this. I certainly woudn’t trade functionality (Android) to screen latency (iphone), but it would be nice to have that one last thing too.
To be honest, the lag is acceptable for 5″> devices, you don’t have much space to move your fingers around unless you’re a died hard Fruit Ninja fan. As Microsoft mention, they want to improve this on the TABLET size devices, so we shouldn’t take the debate on smartphones.
I admit that Apple’s hardware is the best around, other OEM is lacking what I call a united standard, Samsung has their way, HTC has the philosophy, Sony has … etc…
You win this fight Apple, because Android doesn’t care.
Where are the Android fans now?? 😀
This doesn’t account for the slow animations on the iPhone 5S operating system…try unlocking it and opening an app, it won’t let you till the animation is finished… this is the same all over the OS
