When a new touchscreen smartphone comes out, one of the first things we want to find out is how good a touchscreen it has. Well we can read all the reviews we want, watch all the hands-on videos we can and search Google for answers we won’t find. But now there is a definitive way to sort out the good touch screens from the bad ones.
Moto Development Labs has devised a simple way to analyse the accuracy of a capacitive touchscreen using nothing more than a simple drawing program. They demonstrated how they compared the different touchscreen’s of the iPhone, HTC Droid Eris, Motorola Droid, and Nexus One. The results easily show us the differences between the touchscreen’s on each of the smartphones.
So what do these criss-cross patterns mean? Well to achieve them, all you have to do is open up a simple drawing app on your smartphone, then you draw a series of diagonal lines slowly from one side of the screen to the other until your left with a criss-cross pattern on your screen.
The straighter the lines, the more accurate the touchscreen, if the lines are wavy or jagged, well lets just say the touchscreen isn’t what it should be.
The first phone they tested was the iPhone, and as we can see the lines are relatively straight apart from at the edges where the screen seems to lose some of its accuracy. The worst of the bunch is the Motorola Droid which looks more like a jigsaw puzzle compared to the iPhone. These jagged lines show that the Droids touchscreen could cause you to miss a letter on an on-screen keyboard, luckily for the Droid it has a physical keyboard.
The Nexus One and HTC Droid Eris fared pretty well but not quite as good as the iPhone. They were more accurate however at the edges of their screens compared to the iPhone.
