Touchscreen Showdown: iPhone vs Nexus One vs Droid vs Eris
Almost immediately after the launch of the iPhone, competitors were trying to dethrone Apple with their own touchscreen handhelds. These days, if it doesn’t have a touchscreen, it’s yesterday’s news, and touching the screen to interact with your phone is now commonplace. However, all touchscreens are not created equal, as a study published by MOTO labs (no relation to Motorola) confirms. The results show clear differences between the iPhone and others, exposing the copycats for what they are.
They tested the sensitivity of the touchscreens for some of the most popular touchscreen phones on the market by drawing straight diagonal lines across the screens from edge to edge to show how accurately it can track it’s movement. They tested first by using the corner edge of the fingertip with less surface area using light pressure. Then they tried it again, using the tip of the finger (slightly more surface area) with medium pressure. The results were clearly different for every device, as you can see below:
As you can see, the iPhone was able to track the finger at both positions and pressures the best of the four devices, proving it to be the most accurately sensitive, although sensitivity does decrease near the edges. I’m sure you’re wondering why this matters, since I’m guessing drawing perfectly straight diagonal lines isn’t the most important thing you use your iPhone for. The point is that because it’s more accurate, it’s easier to do things on the screen that require precision, like clicking on tiny web links in Safari without zooming in.
