We made some paper prototypes of our app to see how people would use it and which kinds of troubles they have while using it. We started with making a cardboard Smartphone, Smart TV and tablet. We then took big papers and started drawing every possible screen on there, so we could take the cardboard devices and go over the screens on the paper.
In the beginning it was difficult to figure out which had to be on which screen because none of us made this before. There were still so many aspects which were unknown so we had to fill them in.
Afterwards we made these paper sketches digital by using the app Protosketch. You first take photos of the paper sketches with the app, and then you link each photo to another. Later the app connects them all and you can click on the sketches you made… et voila! You have a digital sketch.
We use all of this work to understand how our concept will work in a visual way. Also we test it with some children, and now we are working on the different features that the prototype will have, like the scanning or the trading of the stickers.
