I'm a student currently learning about Interaction Design, on Exchange from Canada in Germany. A group that I am working with is developing an iPhone application aimed at helping cancer patients organize a wide variety of tasks and self-care needs that come with the disease. I have worked on projects with the iPhone before, as an intern and developer. I don't have any experience though mocking up the application on the iPhone, without going through the process of actually building it.
Ideally, we would love to have an interactive mock-up of the application on the iPhone for our final presentation. We're fairly sure that this is infeasible though, as we don't think that actually building it would be the best use of our time. Flash doesn't seem like an option, unless perhaps we create a video using flash, and then have an actor "interact" with the application?
I have been reading this list for a while, and it seems like there are a lot of incredible people connected to it, with amazing experiences to share. Any suggestions that you may have to offer would be greatly appreciated.
