Due to the nature of our application, we wanted to emphasize testing the usability of our user interactions. As such, we focused primarily on trying to figure out the user's intuition for performing various interactions. Our goal is to have common actions be highly intuitive, so this prototype is our chance to test if they are intuitive enough. Our prototype is therefore low fidelity in breadth; the side panels are not very accurately represented since they should not be used in the tasks at all.
Unfortunately, one problem of the paper prototype is that it is not a computer. The user may not apply the same intuition as he would if he were using a computer application with the same mechanics. Therefore, we were not too picky with the details of running the prototype. If the user seems to be performing the right interaction, we let it pass. We did not expect users to be very accurate with their finger pointers.
