Touchscreen Accuracy Issues Plague Droid Devices

If you’ve ever had a debate with a friend who swears by their Verizon Droid, here’s some ammo for your next discussion. A recent analysis highlighted on AppleInsider this morning reveals that the iPhone’s touchscreen outperforms that of several Android devices, including the Motorola Droid, HTC Droid Eris, and Google Nexus One, in terms of accuracy. This is crucial for tasks like tapping links on websites, where the iPhone reportedly offers a higher success rate.

The study, conducted by MOTO Development Group (which is not affiliated with Motorola), utilized a straightforward method to assess touchscreen precision.

Testers opened a drawing application on each phone and drew diagonal lines across the screen using varying degrees of pressure. The result? iPhones consistently displayed straight lines, whereas Android phones exhibited wavy, zig-zag lines under the same conditions. According to MOTO:

“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.”

This finding has been corroborated by several user comments on the MOTO website. We’re curious to hear from TUAW readers as well.
