Apple's iPhone reigned supreme, followed from a distance by the Google Nexus One

Touchscreen Tests Humans remain a mite more wobbly than robots MOTO

MOTO labs already won us over by running comparison tests of smartphone touchscreens, but commentators complained about the possible inaccuracies of a human-finger methodology. That prompted MOTO to program its lab robot to redraw the line patterns with a steadier yet lighter finger that truly challenged the sensitivity of each touchscreen.

The MOTO lab folk ran both "medium touch" and "very light touch" tests with the robot finger on each of the four smartphones previously tested with human fingers, and threw in a Blackberry Storm 2 and Palm Pre for good measure.

So who came out on top? Apple's iPhone touchscreen bested the competition by a good margin, but Google's Nexus One and the HTC Droid Eris also turned in solid performances. The Motorola Droid fared the worst and ran into trouble even on the "medium touch" test, while both the Palm and Blackberry devices showed signal loss on the "very light touch" test.

Take a look at MOTO's light-fingered robot in action:

You do realize that the Palm Pre is a smartphone, right?

@semibreve42 Good clarification point, thanks -- I was mentally separating out the first four smartphones used in the human-finger only test. Fixing that.

hmm... they're trying to run a test on different hardware (even between the android devices) over different operating systems using a program that was tailored for which? I thought in the scientific method you're supposed to eliminate variables. If I take a honda motor and plopped it in a toyota chassis I wouldn't expect it to run as well either. This isn't scientific at all... its a biased experiment to favor the iphone. fail.

I don't see how this is a biased experiment, they just ran a test to see which phone has better tracking. To use your analogy, your saying they took different motorcycles and performance tested them on the same track, and because the track wasn't tuned for each different motorcycle the results are somehow biased towards whichever one performed the best. Part of creating a touch screen phone is designing the screen to track movement on top of it. Something this test shows the iphone does better than the other tested phones.

Not only that, but the guy running the test even says that the test they ran, only tests one component of touch screens.

I swear, anti-appleism is becoming just as rampant as apple fanboyism...it's ridiculous.

To me it looked like the Nexus was the most accurate of the four, especially along the edges. The iPhone is inaccurate in the corners and along the edges which is evident in the human image but not in the robot and I suspect that's only because they did not run the robot finger through a corner. And I wonder at what speed they drew the lines. If it was slowly drawn the imperfections seen in the lines with the human finger would actually indicate greater accuracy apart from a quick swipe of a finger which would draw a smoother line. So this conclusion in biased in hoping to declare a winner without more details. The only thing I can really speculate is that the Droid loses.

@jordan harvey... Your example of the motorcycles on the same track doesn't address the issue because the track is external. On this experiment the testing equipment is run within the confines of the different OS environments and hardware. Here's another example: When firefox and chrome develop their browsers for windows and mac there were obvious performance differences until they could * tweak* the software to make it run better on mac. The performance of the computers themselves was not the factor that determined their usability but rather the software that was tailored for it.

What I said, wasn't an apple bash... it was a dispute of an unwarranted apple praise report... which there is, far too much of, and that's what's.. ridiculous.
