  • iPhone Beats Droid Touch Accuracy in Test


    As users become increasingly used to touchscreens on their phones, the accuracy of the screen's sensing ability begins to become more and more a factor in ease of use and overall satisfaction. A recent test by Moto Development Labs (apparently no connection to Motorola) seems to give the edge to the iPhone's touchscreen: it beat out the Motorola Droid, the HTC Droid Eris and the Google Nexus One (manufactured by HTC) in touch accuracy.

    Moto Labs used a fairly simple method: drawing a diagonal pattern of straight lines very slowly across the screen of each test phone. If the sensing is accurate, the resulting drawing should be made up of straight, unbroken lines, rather than wavy lines. Most of the tests showed the iPhone drawing clear, orderly lines across most of the screen area, though distorting to curves and losing sensitivity at the edges of the screen. The Nexus One and DROID Eris gave good results, though worse than the iPhone overall, ending up with mostly straight lines and maintaining sensitivity out to the edges. The Motorola DROID gave the poorest results, with all tests showing wavy or stair-stepped lines.

    The design and consulting firm, with offices in San Francisco and Hong Kong, imputed the results to some combination of coarse sensor grid, sample rate and/or software:

    On inferior touchscreens, itís basically impossible to draw straight lines. Instead, the lines look jagged or zig-zag, no matter how slowly you go, because the sensor size is too big, the touch-sampling rate is too low, and/or the algorithms that convert gestures into images are too non-linear to faithfully represent user inputs.
    The recommendation? Donít skimp on materials, Moto Labs says, allow lots of time for algorithm development so that the software works well with and error-checks the specific implementation of hardware on the device, and closely integrate the hardware, software, and user interaction development as early as possible in the development process, rather than treating them as separate tasks.

      iDon't draw chain link fences. Droid does.

      No wonder the iPhone is more superior than the others.

      its like when you go to the supermarket and sign on the touch sensitive screen after using a credit card and your signature comes out looking like a 2 year old child wrote it. inferior technology android is. nuf said.

      A nice responsive touch screen is great and all but it's not that much better, Nexus Oneís AMOLED is far more superior to iPhoneís LCD screen; the screen is bigger, the resolution is higher, not to mention the screen ratio 3.5>>>>>3:2

      That's a stupid test. I hope Apple will put out an iPhone next year, that will blow the droid away.

But i also, agree with you that other hardware such as memory and processor are a definite plus and are needed. But i still need a nice responsive touch screen to go along with it.
      You're missing the point here buddy. They're not testing how responsive it is, they're testing its ability to draw lines.

      Guessing it would beat the iPhone the same way the iPhone beat the droid
      Wonder no more. Just look at the fourth phone in the pic in the original post.

      I don't know what you guys experience; however, when I use my Ipod touch in comparison to my HTC Magic, I can't notice anything that would be in any way similar to those graphs, just all straight lines.

      I can't replicate it, so I am left to assume that the "test" is a slander.

      The pics look outrageous tbh, making the different devices look entirely unusable.

      P.S. Nice to know that the iPhone can draw straight lines..... not.
      Ive never dropped a call, havent been in a place where i dont have service. Sure, ive been in spots where i only get 1-2 but those are in hilled areas.

      The iphone is one of the fastest loading phones out there. I think it was tech crunch that did a test between the droid, nexus one, and iphone to load their website when all three had full 3g coverage and the iphone kicked their ***.

      I'm not missing the point at all. The lines that you see are co-related to the responsiveness of the touch screen. Based on the article the straighter the lines the more accuracy you will have when touching the screen.

      It would be interesting to see just how many iPhone 2G/3G/3Gs owners have had "consistent" trouble with their service (dropped calls, no 3G, poor 2G, poor reception, slow internet speeds while on, etc..) and those who have not.

      AT&T and Apple thought it was a big enough issue that they created the "Mark The Spot" app. Maybe a poll on this website would vet this issue out among its members.

      I sit corrected. I was just thinking of responsiveness in the aspect of opening/closing/switching applications and features. Credit given where credit is due.

      i hate how the iphone swerves off at the edges, i tried this and it was horrible, but i guess its still better than having swiggly lines through the whole thing
