This was a super efficient storyboard. In it, Amberlee presses find, picks the fantasy genre, and scrolls to find a book. The idea was that the only typing would be entering the name of a book (possibly writing a summary). That way, users who are in a hurry at a book store would only have to press buttons. In class, it was suggested that a dropdown menu or auto complete would have actually been more efficient.
Storyboard 3:
We chose the Mobile design as one of our three final designs.
Efficiency: I sacrificed a bit of efficiency in order to make it more learnable. Despite this, It is very efficient overall, by alternating between three panels, such that no action requires more than three touches.
Learnability: The application makes use of colors and color coding to maximize learnability. It is very simple and has a UI similar to Facebook. Since most high school students are familiar with Facebook, they can easily figure out how to use the application.
Safety: The design is very safe, since it uses large, color-coded icons, such that mistakes are unlikely, and has an easily accessible navigation panel to give access to every section of the application, such that mistakes are easily recoverable. However, it could make more use of clearly distinguishable colors in order to make it more safe. Furthermore, it includes a "Back" button on every page to revert from any page to the previous.
