I'm designing a mobile (phone/tablet) application where one of its primary uses will involve taking surveys. These surveys already exist on paper, and many of the questions make use of a Likert Scale.
In web based applications, a Likert scale question is typically presented as matrix of radio inputs. However, I don't think this presentation is suitable for mobile applications, where screen real estate is limited. Instead, I thought to use drop downs (specifically, Android spinners).
Will this possibly be hard to use? I've thought about alternatively using snapping sliders as well. Any suggestions? (Note that I didn't come up with the questions/answers)
