I'm interested in digital magazines on tablet devices, especially on the iPad.
With magazines that already exist in print, i've noticed at least two different concepts for digital editions of said magazines, the lazy approach, simple reproductions, often only a PDF inside an app, or magazines that are tailored to the iPad screen and may also contain interactive elements.
As part of a bachelor thesis, i would like to evaluate a number of different magazines, but the only existing guidelines i have found are from the NN Group (the 2011 evaluation of the usability of the iPad and its apps) and are not very detailed.
They are very useful for basic stuff, making sure that navigation inside the magazine is always as expected, but imho they are lacking other things, like any mention of resizeable fonts in the magazine-specific case study.
Now i'd guess i have to create my own guidelines, so detailed that they could be passed to someone without any knowledge of usability and still help him to design or evaluate.
So, does anyone know of any really detailed guidelines for design and evaluation of digital magazines on a tablet?
