MOTO Development has posted results of a DIY touchscreen analysis for the Apple iPhone, Motorola Droid, HTC Droid Eris, and Google Nexus One.

MOTO evaluated the resolution and accuracy of each touchscreen device. They used a very simple technique that anyone can perform at home. The results are very interesting. The iPhone’s touch sensor showed the most linear tracking with the least amount of stair-stepping. The Droid Eris and Nexus One tied for second with only faint wiggling – but actually performed best at the edge of the screen. Last in the line-up was the Motorola Droid, which demonstrated significant wavy artifacts or “stair-stepping.
