Smartphones tested for accuracy with robot precision: iPhone wins

Comparing the performance of the touchscreen interface on today's smartphones is a notoriously tricky business.  Any challenge that involves tapping the screen to check how accurate it is will struggle to maintain its independence due to the human error introduced by wavering fingers.


That's why the engineers at Moto used a robot to trace perfectly straight lines across a series of popular touchscreen handsets to see how they performed.  The results showed the iPhone has the most accurate touchscreen  out of the six challengers.  Motorola's Milestone (aka Droid) did particularly badly, but as you can see in the results below, just about all of the handsets struggled in the corners, something that many users have found frustrating.
