Hands down, forms are probably one of the most annoying topics when it comes to user interfaces. For users as well as for designers it seems to be an odyssey, brimming with bad experiences. In the last couple of months, I have been working in a lot of projects involving interfaces for mobile devices in all shapes and colors. For me, it was very interesting to observe in user testing how my designs as well as the designs of colleagues, although all of them seemed to be very informed and sometimes clever solutions, finally were torn apart by users.

As designing mobile interfaces is still pretty much virgin soil for a lot of people and as there are not a lot of useful guidelines, I started to write down all the common problems, that I observed. Embedded into a little bit of prose, the guys from Smashing just recently featured those notes. The original article can be found on Smashing Magazine.
