The day that Thomas Edison invented the movie camera, nobody really knew how to make a good movie.
All the camera techniques and tools till then were designed specifically for still photography and didn’t help with moving images.
Those first filmmakers needed to invent brand new tools and techniques that were much better suited to making movies — methods such as storyboarding, editing and later sound recording.
I think web design has gone through a similar transition.
We spent the first 15 years building static designs on pages with fixed dimensions.
The explosion of mobile in the last five years has changed everything, and the idea of presenting static, fixed-size mock-ups to our clients and colleagues is making less sense every day. We can’t pitch a movie with a poster – we need new tools.
##Rise of the Prototyper
The last two years could be seen as the rise the prototype tool. While there has been prototyping software around since the mid-2000’s, the field has boomed with the growth of mobile.
Today I’m going to walk you through one of these tools that takes a slightly different approach – it’s called ‘Appseed’.
##What’s Appseed?
Appseed is a prototyping tool aimed primarily at people designing for mobile. Perhaps the first thing you need to know about Appseed is that you can’t install it on your computer. You can’t even access it via your browser. Appseed runs entirely on your IOS phone or tablet.
The idea is that you’re laying out the interface and the planning the interactions directly on the device you are targeting.
