I find differentiating prototypes from wireframes (Well, as long as we’re in a medium where that makes sense) quite difficult. As I described in my previous blog, a wireframe should be flexible, with few set boundaries and solely used as a tool to communicate precisely what you want – what’re the boundaries then between a high-fi wireframe which is nearly functional and a prototype? Who knows. Not me.
There are things out there which have tried to bridge the gap, dreamweaver, Macaw, and a few others… but nothing yet has made the experience simple and intuitive, while keeping the same power as a text editor. Maybe that’s the issue – they’re at odds with each other. But I don’t think they have to be.
