According to a report cited on AppleInsider this morning, the touchscreen accuracy of the iPhone is much better than that of three Android phones: the Motorola Droid pushed by Verizon, the HTC Droid Eris, and the new Google Nexus One. Why is that important? Well, when you're trying to tap a link on a website, for example, chances are very good that you're going to be successful on the iPhone and not on the Android phones.
The tests, performed by MOTO Development Group (no relation to Motorola), measured touchscreen accuracy with a simple test. On each device, a drawing app was launched and a tester drew straight diagonal lines in both directions across the screens with a finger. iPhones showed straight lines in situations with both light and medium finger pressure, while the Android phones showed zig-zag wavy lines across the screen. MOTO stated:
Several user comments on the MOTO site validate the findings. Have any TUAW readers been able to compare touchscreen accuracy on an iPhone and an Android device? Leave a comment below."On inferior touchscreens, it's 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. This is important because quick keyboard use and light flicks on the screen really push the limits of the touch panel's ability to sense."
