iPhone tops several Android phones on touchscreen accuracy
Touchscreens are becoming increasingly common in consumer-level smartphones, but they work more smoothly in some phones than others. MOTO, a company that develops products and services for startups (and has done some work on capacitive touch), recently did some touchscreen analysis on a handful of smartphones and found that the iPhone had some of the best screen/software integration of the bunch.
MOTO noted in its post that good touchscreens require seamless integration between hardware, software, and UI, and that the user will undoubtedly suffer if a manufacturer decides to cut corners in this process. To test this, MOTO performed a line test as a way to see how well these elements were integrated—the goal is to see how smooth and straight the lines are when you draw them slowly with your finger. “On inferior touchscreens, it’s basically impossible to draw straight lines,” the company wrote. “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.”
