iPhone Wins Smartphone Touchscreen Shootout

- By - Source : Tom's Guide US

With the advent of the touch screen phone, now to the point where many phones are ditching the tactile keypad altogether, the use of responsive and accurate technology is more important than ever.

The iPhone took the capacity touch screen and ran with it. While capacity touch has the downside of not working for users wearing gloves or those who wish to tap with fingernails, the technology is currently best suited for small devices that require accurate and discrete sensing for things such as an onscreen keyboard.

Moto Development Group has taken it upon themselves to test the leading touch screen smart phones today to see which one has the most accurate and consistent sensors. The image below tells nearly the full story:

The test is pretty faulty if you read into it. It makes a lot of assumptions on how the different manufacturers designed their phones to work and also uses a human (!!!!) finger for the tests. They should have used a mechanical apparatus for all of the phones with precise tracks and pressures, along with a program to evaluate the pictures and come up with hard numbers on just how much deviation there was.

mianmian :
Though human finger is not as accurate as machine, it's accurate enough for this test.



That's not the point - the point is the finger isn't precise enough to give consistent results across multiple tests. Whenever running a scientific test, you should never, ever, use a human to directly interact with the test whenever possible. We can't do something the exact same way even twice, let alone the 12 times this test used.

what am I looking for in the images above? straight lines or what? cos to me it looks like the last phone (nexus one I think it says) is pretty much the same in that respect, if not, better.

With more controlled condition, it's possible to obtain more accurate result with numbers. But that requires special instrument that they may not get easily. You do not always need a stopwatch to figure out who runs faster.

I would think that the human finger is exactly what you would want to use for a test of the screens ability to acturately convey input from the human finger. /shrug

Are you blind or just ignorant?Look at the iPhone lines, they are straight just as they should in BOTH tests. In the topmost test not a single line on the other phones are straight. If a finger is so inconsistent they should be able to at least by chance get ONE straight line. They didn't. You have to press harder on their screens to get the result you want which is highly annoying!It Seems to me like you're just making up excuses for putting an inferior screen in the phone. I guess a low price is more important than a good screen to those exposed too long to PCs.



It's nice how you're talking to me as if I'm attacking the iPhone for winning. I'm not the only one who called foul - read the comments on the article. There's a number of other factors in play here other than just the finger...screen resolutions, the program used across the platforms, the algorithms used to interpret finger input with this particular type of test...I'm not saying that one phone is better than the other (I don't own any of these; I've got an HTC Touch Pro with a resistive screen, which I prefer), I'm just saying this test doesn't prove anything at all - it's not even a good way to test a touchscreen. There are numerous other tests one could have used that are more decisive - like link accuracy on a given webpage. That doesn't require a 3rd party program, is standard on all of the phones, and is relevant to actually using the phone itself - they were all designed to perform that function.

In any evaluation of technology, it's always useful to have objective and subjective testing, i.e. tests that can be reproduced every time with clear, non-biased results and tests that attempt to measure the human evaluation of a technology. I think the point about needing subjective results is valid (otherwise, how would the manufacturer know people like it?). But objective results are more useful when comparing measurable statistics, like performance timings, refresh rates, etc.

It's pretty obvious no one in this test cared to gauge things objectively. That may suffice for some, but the basis of the test sure sounds like it requires more objectivity.

In the original article there is much emphasis placed on how the line "bends" near the edge of the screen. I would suggest the next test would take into account the physical edges of the screen, i.e. the actual design / manufacturing of the phone. If you meet a raised margin, the line WILL bend.
Also, what exactly is the utility of the test? And where are other phones for that matter? The Hero and the HD2 are missing and they also have capacitive screens.
My friend, an iPhone owner, bitches about the screen of his device when side by side to an HD2.
And no resolution taken into account? Seriously, my kids could have designed a better testing method. Talk about bias there...

I could make a mechanical test for this with parts from any junkyard or stuff found in your basement. It's really not that hard.

note the exclusion of nokia.... why? why lea\/e out the best phone on the market?

I like how it's completely ignored that the Android phones have TWICE as many pixels than the iPhone when declaring the "winner".

I have an LG Arena. Touchscreen is great but the phone sucks elephant spunk. Worst purchase I ever made. The software is awful and I can't believe I was dumb enough to buy it. So touchscreen tests are reasonably irrelevant if you are trying to work out who makes the best phone. As long as the screen works well enough that is.

In fact I'm going to replicate this test with my LG Arena using my dick. Then when T-Mobile come to swap it tomorrow morning (for another crappy won't work Arena!) they can perform tests on any 'foreign bodies' they find smeared on the screen.

As far as im concerned if its touchscreen I do not want it. Ive had my LG Voyager for the 2 year contract and hated every minute of it, played with an Iphone, hated it...Used a LG Dare, hated it. I can't use a full qwerty keyboard as small as what is used on cell phones without having to look at it. If I can't text with one hand and not have to look at my phone to do it, I don't want it. Give me a flip phone with T9 anyday over touchscreen/qwerty keypad. My next phone will be a cheapo flip phone because of this. All I do is text so typing without looking is a must. I talk maybe 300 minutes a month and have sent and recieved well over 10k+ texts in that same period.

Iphone is the best phone I've used to date. Enough with the negative comments already.

would love to see some results for nokia's N900 and 5800expressmusic.
did some searching... ended up with nothing.

Probably your experience is equal or less than that of the authors of this "study".
no offense, but try to broaden your horizons a bit.

The whole point of a capacitive screen is that it relies on the conductivity and bio-electrics of a living human finger to work properly - I call foul on any 'scientific' test that uses anything different unless they can demonstrate beyond a shadow of a doubt that the actuator they used had absolutely identical electo-mechanical properties asa real, living, finger.

They didn't use an actuator, they asked humans to draw lines with their fingers. They didn't even specify which finger (thumb or index) was used. An actuated simulated finger would need to be shown that it was a reliable replacement (ie draws straight lines on paper) and then it would be a viable test apparatus. This test is also severally limited as it uses 3 devices that are essentially the same, and judge it against 1 other device. Where are the Nokia, Palm, etc phones?!
