Consulting house MOTO Development Group has performed an analysis of smartphone touchscreen sensitivity, putting the iPhone up against three Android-powered rivals: the HTC Droid Eris, the Motorola Droid, and the newly released Google Nexus One. The test used a drawing app to attempt to draw straight lines in a diamond pattern across each screen using both light and medium finger pressure.
As the report notes, “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.” The iPhone was the winner of the overall performance test, creating fairly straight lines compared to its competitors, but lagged behind the other offerings in edge performance, with noticeable curving of the lines as they reached the edges of the screen.
