also not related particularly to User Interfaces but you may try using Ideo Method Cards. These are an aid to designers in a variety of projects and they help to prioritize design elements and classify user requirements. the cards are divided into four categories Learn, Look, Ask, Try and each card outlines an exercise the designer may use to get closer to her design goals. some of them are quite fun as well. http://www.ideo.com/methodcards/MethodDeck/index.html
