Did Samsung pay this company to do this test? I'm forever skeptical after cheating specs, and paying for comments.

Testing Finds Inaccurate Touch Sensing on iPhone 5s/5c, But Neglects Perspective Compensation

It is intentional by Apple.
Try to touch some buttons if the UI is upside down... difficult, isnt it?
Guess why
(Apple offsets the touch so that your eye-finger-button line is straight on the target)
That is awesome! I always wondered why I missed buttons when holding my phone upside-down.
but not everyone is left handed.. and not everyone mainly uses their phones in portrait.. so am i missing something? wouldn't you want the touch sensitivity to be completely even throughout the display?
Sorry pal, your device works just the same way. Put the rotational lock on, turn it upside down and try to hit some buttons...
Difficult now? Yes
Youre holding it wrong now and Apple tried to make it easier for you if you just would use it holding it the right way
Every iOS device will fail in this a touch must hit the exact pixel below it-contest.
Apple compensates your line of view and offsets the touch by some pixels to make it easier for your brain and fingers to hit the spot you want to.
You have plenty of excuses for the iPhone when it proves inferior with touch sensing, but when it wins on other tests like speed of browser opening, it's a totally legit test.
Good one.
Good one.
This explains why I keep selecting C instead of V, deleting letters when I select M and get P when I want O.
Had this problem on the 5 and have it on the 5s. Thought it was my sausage fingers, but then realised I never had an issue on the iPhone 4 and 4s.

the touch id sensor hates my fingers that have scars. Which is stange. You would think a large vertical scar would be a distinguishing feature.
i kno. but apple has the patents for the screens made by the other guys who can't replicate the same functionality they give to apple.
...the person I replied to said they INTENTIONALLY made the screen less responsive in other areas.
I find this very interesting. I never understood why using the phone upside down was so hard. Now I know. I typically show people where to go in settings to help them find or change something so I'm facing the person and they're holding the phone and I'm directly in front of them. It's hard to use the phone that way.
Someone mentioned looking at your thumb and the angle it hits. I did this and found something interesting. As a right handed person, holding the phone in my right hand and using the thumb to touch (the most natural position I think) the thumb hits closer to 90º in the area that tested green on their tests. The other areas, the angles change drastically. To the right, my thumb is 45º or so tilted to the right, at the top of the screen, it's about 45º tilted towards the bottom. If there's compensation, which it sounds like there is, you would have to overcompensate twice as much with the phone upside down because you're now dealing with an angle 90º off of the intended angle for the device. Genius Apple. This is why, to a robot at 90º, the Samsungs are perfect. For people, The Samsungs are non responsive. I have never had an issue with my phone (except for when they're upside down or I'm showing someone something) and I know people who have complained about it on other devices. I do understand however that just cause I've never had an issue with it doesn't mean others are. To take a page out of the great Steve Jobs, if you're touch is off on the edge of the device, you're holding it wrong. The software is programmed to compensate for certain angles it seems like. My 2 cents.
Edit: I do have an issue, I just never realized it. When I type a message, I typically hit space twice afterwords and hit delete. (Why I don't just type period? I don't know. It's just what I do.) I have on several occasions hit M instead of Delete though. Which is strange because my first name doesn't start with an M, but it looks like I'm signing the message.
I.E.
I'm on my way. M

I don't know what these guys are measuring, on my
iPhone4S it take about a second or two at the most. My guess, it will be same for S3 and S4 too. Who are these people and what are they actually testing? Sorry pal, your device works just the same way. Put the rotational lock on, turn it upside down and try to hit some buttons...

Apple compensates your line of view and offsets the touch by some pixels to make it easier for your brain and fingers to hit the spot you want to.
I didn't even realise it was happening to be honest. Never noticed any issues with touch so far.
No, they made it easier to use. In the real world, your device is held in front of you below eye level and away from you. The compensation is most noticeable when you have the iPhone on the table slightly away from you. Try pressing a button, but hold your finger there. Now bring your head directly above the screen and you will probably see your finger is a few mm below the actual button. Without the compensation, the button would have never registered a tap because technically the tappable area wasn't that far below.
I've noticed things closer to the home button will have touch targets directly on the tappable area whereas the touch targets near the top of the screen will have their tappable area shifted down to compensate for perspective.
The device determines this compensation by looking at the orientation of the device, and I wouldn't be surprised if Apple uses the gyro to determine tilt of device too.
You're not supposed to notice it
It's reminds me of how the Greeks made the Parthenon with curved lines so when you look at the building, the lines actually look straight due to perspective. Usability and having the device do what you expect without having you to think about it is better than any benchmark.
Right-handed, actually. Hold your phone... if you're right handed, your thumb lands on the left side of the screen, and normally the bottom-left side is straight on with your eye, with increasing angles on the rest of the screen. hence, the bias they've programmed in. This isn't a problem or error or "bad" thing like the study seems to think... this is intentional to make the user experience better.
Exactly. Comparing my iPad mini to my Nexus 4 I notice there is still a gap between iOS accuracy and Andriod touch panel accuracy. The Nexus isn't bad, but just not as good.
----------
So what you are saying is the testing device is holding it wrong.
I agree, I found my iPhone 5s accuracy superior than Galaxy and Nexus for my hands - but I would encourage others to try them side-by-side as well.
My initial expectation is that out-of-the box, the default for most displays, would perform at 90 degrees for *all areas* of the display and that extra effort has to be made to make it behave different.
The title is a misnomer, should be little more like: Testing shows that Apple adds adjustments for perspective touch sensing for displays.
.
This is why Apple products are just so well designed over its android counterparts.
Touch screen on my 5s feels incredibly fast and responsive.

And when did +/- 1.0-mm accuracy for a capacitive touch surface matter to users who have fingers with an average width of 11.7-mm?
This is a totally useless statistic concerning customer experience. Users want intuitive UI and quick responses. Unless they are very niche handheld CAD users, they don't care.
